Title: Stereoscopic picture displaying apparatus

Description:
RELATED APPLICATION DATA  
       [0001] The present invention claims priority to Japanese Application No. P2000-141030 filed May 12, 2000, which application is incorporated herein by referenced to the extent permitted by law.  
       BACKGROUND OF THE INVENTION  
       [0002] 1. Field of the Invention  
       [0003] The present invention relates to a stereoscopic picture displaying apparatus enabling a person to stereoscopically look at a photographed picture with a pair of shutter spectacles by photographing picture for a right eye and a picture for a left eye.  
       [0004] 2. Description of the Related Art  
       [0005] A conventional stereoscopic picture displaying apparatus that stereoscopically displays a two-dimensional picture displays a picture for a right eye and a picture for a left eye alternately to have a parallax between two pictures on a display, and switches the states of the shutter section for the right eye and the shutter section for the left eye of a pair of shutter spectacles to take a open state and a closing state synchronously with the switching of the pictures displayed alternately on the display. That is, in the shutter spectacles, when the picture for a right eye is displayed on the display, the shutter section for the right eye is made to be the open state and the shutter section for the left eye is made to be the closing state. Moreover, in the shutter spectacles, when the picture for a left eye is displayed on the display, the shutter section for the left eye is made to be the open state and the shutter section for the right eye is made to be the closing state. As described above, the stereoscopic picture displaying apparatus enables an user to stereoscopically look at a picture by synchronizing the turning on and off of the picture displayed on the display and a pair of shutters on the left side and the right side of the shutter spectacles.  
       [0006] By the way, when the above-mentioned stereoscopic picture displaying apparatus is structured by means of a usual personal computer, a keyboard that is character-inputting means and a mouse that is a position-inputting means are provided as an input unit. Consequently, there are a case where a stereoscopic picture is edited with the mouse and a case where characters are input on a stereoscopic picture with the keyboard.  
       [0007] However, for example, if a pointer of the mouse moves on a stereoscopic picture when the stereoscopic picture is displayed on the display, it becomes hard for an user to look at the pointer because the pointer is displayed in flat without any parallax. Moreover, if characters are displayed in flat without any parallax when the character is input on a stereoscopic picture displayed on the display, it becomes hard for an user to look at the characters.  
       [0008] Moreover, when a stereoscopic picture is displayed on a part of a screen on the display, a screen region where there is no stereoscopic picture is displayed in flat. For example, icons and other objects are displayed in the region. Consequently, because the region where the stereoscopic picture is displayed and the region where a flat display mode is performed are simultaneously formed on the same screen, it becomes hard for an user to look at the stereoscopic picture.  
       SUMMARY OF THE INVENTION  
       [0009] Accordingly, an object of the present invention is to provide a stereoscopic picture displaying apparatus that makes it easy for an user to look at a stereoscopic picture displayed on a display.  
       [0010] That is, the object of the present invention is to provide a stereoscopic picture displaying apparatus capable of making it easy for an user to look at pointing means on a stereoscopic picture by displaying the pointing means so that the pointing means has also a parallax in accordance with the parallax of the stereoscopic picture at the position where a pointing means is located when the pointing means is on the stereoscopic picture.  
       [0011] Moreover, another object of the present invention is to provide a stereoscopic picture displaying apparatus capable of making it easy for an user to look at characters displayed on a stereoscopic picture by displaying the characters so that the character has a parallax in accordance with the amount of the parallax of the stereoscopic picture at the position where the characters are displayed when the characters are displayed on the stereoscopic picture.  
       [0012] Moreover, still another object of the present invention is to provide a stereoscopic picture displaying apparatus making it easy for an user to look at a stereoscopic picture by displaying a frame body having a parallax around the stereoscopic picture displayed on display means.

       [0014] In accordance with another aspect of the present invention, the foregoing and other objects and advantages are attained by a stereoscopic picture displaying apparatus that comprises: memory means for storing data of a stereoscopic picture including a picture for a right eye and a picture for a left eye; display means for displaying the picture for a right eye and the picture for a left eye on a basis of the data of the stereoscopic picture stored in the memory means; character-inputting means for inputting a character to be displayed on a screen to the display means; and controlling means for controlling the display means to display the picture for a right eye and the picture for a left eye alternately on the display means so as to have a parallax. Then, the controlling means controls the display means to display a character so as to have a parallax in accordance with an amount of the parallax at a position at which the character is input on the screen when the character is input at a prescribed position on the stereoscopic picture with the character-inputting means. In accordance with a further aspect of the present invention, the foregoing and other objects and advantages are attained by a stereoscopic picture displaying apparatus that comprises: memory means for storing data of a stereoscopic picture including a picture for a right eye and a picture for a left eye; display means for displaying the picture for a right eye and the picture for a left eye on a basis of the data of the stereoscopic picture stored in the memory means; and controlling means for controlling the display means to display the picture for a right eye and the picture for a left eye alternately on the display means so as to have a parallax.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS  
     [0050] Hereinafter, a stereoscopic picture displaying system to which the present invention is applied will be described by reference to the attached drawings.  
     [0051] As shown in FIG. 1, a stereoscopic picture displaying system  1  to which the present invention is applied is composed of a digital camera  2  for photographing a picture, a controlling unit  3  for taking in picture data generated by the digital camera  2  to perform a data processing of the picture data taken for displaying a picture having a parallax on a display  55 , and a pair of shutter spectacles  4  that blinds in turn an eye of an user synchronously with the pictures displayed on the display  55 . Moreover, an adapter  5  for taking in a picture for a right eye and a picture for a left eye is attached to a lens-barrel  2   a , in which an imaging lens, a focusing lens, a zoom lens and other lenses are assembled, of the digital camera  2 . Thereby, a picture for a right eye and a picture for a left eye are taken in by one CCD element used in the digital camera  2 . Then, the data of a picture including a picture for a right eye and a picture for a left eye that are generated by the digital camera  2  are supplied to the controlling unit  3 . The controlling unit  3  picks up, for example, a picture for a right eye and a picture for a left eye on the basis of an input signal from an input unit  57  composed of a keyboard  57   a  as a character-inputting means, a mouse  57   b  as a position-inputting means for operating a pointing position of a pointing means such as a pointer, and other inputting devices. Then, the controlling unit  3  alternately displays the picked up picture for a right eye and the picked up picture for a left eye on the displays  55  such as a cathode-ray tube (CRT), a liquid crystal display panel or the like. Moreover, a controlling unit for spectacles  6  for controlling the turning on and off of the shutter spectacles  4  is provided between the controlling unit  3  and the display  55 . The shutter spectacles  4  have a shutter section for the right eye  4   a  and a shutter section for the left eye  4   b , and the shutter section for the right eye  4   a  and the shutter section for the left eye  4   b  are composed by a liquid crystal shutter. Such shutter spectacles  4  are connected with the control unit for spectacles  6 . The shutter spectacles  4  make open and shut the liquid crystal shutter that composes the shutter section  4   a  and the shutter section  4   b  synchronously with the switching of the picture for a right eye and the picture for a left eye that are alternately displayed on the display  55  by the control of the controlling unit for spectacles  6 . Thereby, the user can stereoscopically look at a picture displayed on the display  55  by opening and shutting the shutter sections  4   a  and  4   b  of the shutter spectacles  4  synchronously with the switching of the picked up picture for a right eye and the picked up picture for a left eye that are alternately displayed on the display  55 .  
     [0052] Hereinafter, the digital camera  2 , the controlling unit  3 , the adapter  5  and the controlling unit for spectacles  6 , all constituting the aforesaid stereoscopic picture displaying system  1 , will be described by reference to the drawings.  
     [0053] The digital camera  2  has a structure similar to an ordinary digital still camera. As shown in FIG. 2, the digital camera  2  comprises a CCD element  12  for performing the photoelectric conversion of an incoming light input from an imaging lens  11  to generate an image signal, a correlated double sampling/automatic gain control (CDS/AGC)  13  for eliminating noises of the image signal from the CCD element  12 , an A/D converter  14  for converting the image signal output from the CDS/AGC  13  into a digital signal, and a signal processing section  15  for performing signal processing corresponding to color coding.  
     [0054] The CCD element  12  as an image sensor is a two-dimensional color image sensor having several million pixels, and the CCD element  12  converts imaged light into an image signal processed by color coding with a color coding filter of primary colors (Red, Green, Blue) or complementary colors (Yellow, Cyan, Magenta), and outputs the processed image signal to the CDS/AGC  13 .  
     [0055] The CDS/AGC  13  performs the correlated double sampling and holding of the image signal supplied from the CCD element  12 , and performs the removal of reset noises and the gain control of the processed image signal to output it to the A/D converter  14 .  
     [0056] The A/D converter  14  converts the image signal from the CDS/AGC  13  into a picture data in a digital system. Then, the A/D converter  14  outputs the picture data that is converted into digital data to the signal processing section  15 .  
     [0057] The signal processing section  15  performs a decoding processing and other processing corresponding to the color coding with the color coding filter of the CCD element  12  of the picture data output from the A/D converter  14  to produce brightness information, color difference information and other information from the picture data.  
     [0058] Furthermore, the digital camera  2  also comprises, as shown in FIG. 2, a compressing section  16  for compressing the picture data processed by the signal processing section  15 , a memory  17  for storing the picture data compressed by the compressing section  16 , an interface for Universal Serial Bus (USB)  18  for transmitting the picture data compressed by the compressing section  16  to the controlling unit  3 , an interface for an IC card  19  for transmitting the picture data to an IC card  8  that uses a flash memory and other semiconductor memories as storage medium, and a controlling section  20  for controlling the whole of the digital camera  2 . The picture data is derived from an output terminal  21 .  
     [0059] The compressing section  16  compresses the picture data processed by the signal processing section  15  in a, for example, Joint Photographic Experts Group (JPEG) form. Then, the compressing section  16  outputs the picture data compressed in the JPEG format to the memory  17 , and the picture data compressed in the JPEG format is stored in the memory  17 .  
     [0060] Moreover, the interface for USB  18  transfers, for example, the picture data compressed in the JPEG format and stored in the memory  17  to the controlling unit  3  by way of the output terminal  21 . Besides, the interface for an IC card  19  transfers, for example, the picture data compressed in the JPEG format and stored in the memory  17  to the IC card  8  used as an external storage unit.  
     [0061] The controlling section  20  controls the whole of the digital camera  2 . To put it concretely, the controlling section  20  performs the driving and the controlling of the focusing lens, the zoom lens and other equipment on the basis of an operation signal from an operation section (not shown). Moreover, the controlling section  20  makes the memory  17  store the picture data compressed in the JPEG format. Furthermore, the controlling section  20  also directly transfers the compressed picture data to the controlling unit  3  through the interface for USB  18 , or makes the IC card  8  store the compressed picture data through the interface for IC card  19  without storing the compressed picture data in the memory  17 .  
     [0062] When an image is photographed with the digital camera  2  and the data of the photographed image is stored in the memory  17  of the digital camera  2 , the incoming light input from the imaging lens  11  is converted into electric current as an image signal by the CCD element  12 , and the generated image signal is converted into a digital signal by the A/D converter  14  through the CDS/AGC  13  to generate a picture data. The generated picture data is processed by the signal processing section  15 , and the processed picture data is compressed in the JPEG format by the compressing section  16 . Then, the compressed picture data is stored in the memory  17 . Moreover, when the picture data in the JPEG format that is stored in the memory  17  is stored in the IC card  8 , the controlling section  20  stores the picture data in the IC card  8  mounted on the digital camera  2  through the interface for IC card  19  on the basis of an operation signal from the operation section. Or, when the picture data is transferred to the controlling unit  3  through the interface for USB  18 , the controlling section  20  transfers the picture data to the controlling unit  3  through the interface for USB  18  a n the output terminal  21  in response to an operation signal from the operation section.  
     [0063] By the way, as shown in FIG. 1, the adapter  5  to take in a picture for a right eye and a picture for a left eye is attached to the lens-barrel  2   a  of the digital camera  2 . The adapter  5  is for taking the picture for a right eye and the picture for a left eye in a right side area and in a left side area of the areas divided at about the center of the CCD element  12  used in the digital camera  2 . In the adapter  5 , as shown in FIGS. 3 and 4, first mirrors  33   a  and  33   b  are provided on inner walls of inclined walls  32   a  and  32   b  on both of the left side and the right side that are side walls of an outer housing  31 . Moreover, a partition wall  34  forming a triangle pole is fixed at about the center of the outer housing  31 . A side face  34   c  of the partition wall  34  faces to the front surface of the outer housing  31 , and forms an opening section for a right eye  35   a  and an opening section for a left eye  35   b  for taking in the external light together with the outer housing  31 . Moreover, two side faces  34   a  and  34   b , both adjoining the side face  34   c , are fixed so as to be substantially in parallel with the inclined walls  32   a  and  32   b  of the outer housing  31 , respectively, and second flat mirrors  36   a  and  36   b  are provided on the two side faces  34   a  and  34   b , respectively, so as to be opposed to the first flat mirrors  33   a  and  33   b , respectively. Moreover, an opening part  38  for taking the external light that reflected by the first flat mirrors  33   a  and  33   b  and the second flat mirrors  36   a  and  36   b  into the lens-barrel  2   a  of the digital camera  2  is formed on the back surface wall  37  of the outer housing  31 .  
     [0064] The thus structured adapter  5  is fixed to the front end of the lens-barrel  2   a  so that the opening part  38  is opposed to the imaging lens  11  of the digital camera  2 . Then, the external light R taken in through the opening section for the right eye  35   a  and the external light L taken in through the opening section for the left eye  35   b  are reflected by the first flat mirrors  33   a  and  33   b , respectively, and are reflected by the second flat mirrors  36   a  and  36   b , respectively. Then, the reflected external light R and the reflected external light L are taken into the CCD element  12  of the digital camera  2  through the imaging lens  11  opposed to the opening part  38 . Here, as shown in FIG. 4, when angles of a view at points  39   a  and  39   b  are supposed to be ?, a picture having angle of a view of  2 ? is taken into the CCD element  12 . Moreover, because a distance D between the points  39   a  and  39   b  determines a parallax, the distance D is set to be 65 mm to 70 mm in accordance with an average distance of human eyes. Incidentally, the distance D may be adjustable according to the differences among individuals. Consequently, the picture for a right eye and the picture for a left eye that are distant from each other by the pupil distance are taken into the CCD element  12  so that they are located side by side on the surface of the CCD element  12 .  
     [0065] Now, FIG. 5 shows a picture taken into the CCD element  12  when the adapter  5  is fixed to the digital camera  2 . A picture  41  includes a woman standing by a flower planted in a flowerpot and a mountain located as a background. As shown in FIG. 5, in the picture  41 , a picture for a right eye  41   a  is photographed in the substantially right half of the picture  41  and a picture for a left eye  41   b  is photographed in the substantially left half of the picture  41 , both of the halves being divided by a boundary part  42 . When the picture for a right eye  41   a  and the picture for a left eye  41   b  are compared, for example, the flower  43   a  and the mountain  44   a  in the picture for a right eye  41   a  are slightly shifted to the left side in comparison with the flower  43   b  and the mountain  44   b  in the picture for a left eye  41   b . In such a way, the picture for a right eye  41   a  and the picture for a left eye  41   b  are shifted by the parallax on the right and left sides, namely both the pictures are shifted by the distance D. Incidentally, the boundary part  42  is actually formed as a blurred white line.  
     [0066] Consequently, when photographing is performed with the digital camera  2  to which the adapter  5  is attached, the picture  41  composed of the picture for a right eye  41   a  and the picture for a left eye  41   b  is taken into the CCD element  12 , and the picture data including the data of each of the picture  41  as one unit is stored in the memory  17  and the IC card  8 , and further the picture data is transferred to the controlling unit  3  through the interface for USB  18 . By using such adapter  5 , the digital camera  2  can compose the picture  41  for a stereoscopic picture as one file, and then can facilitate the management thereof. Moreover, because it becomes unnecessary to prepare a timing generator to take the synchronization of each camera like in the conventional case where two cameras are used, the simplification of the configuration can be attained. Moreover, the digital camera  2  to which the adapter  5  is attached can simultaneously photograph the right side picture and the left side picture without using two cameras when static images are continuously photographed to be made as a dynamic image. Moreover, because the digital camera  2  to which the adapter  5  is attached is not necessary to adjust optical axes of two cameras, a zooming function using a zoom lens can also be used.  
     [0067] Next, the controlling unit  3  for editing and displaying the picture data generated by the digital camera  2  to which the adapter  5  is attached, namely the picture data of the picture  41  composed of the picture for a right eye  41   a  and the picture for a left eye  41   b , will be described by reference to FIG. 6.  
     [0068] The controlling unit  3  has substantially the same configuration as that of an ordinary personal computer. The controlling unit  3  comprises a hard disk drive (hereinafter, also referred to as HDD)  51  for storing the aforesaid picture data of the picture  41 , an application program for editing the picture data, an application program for stereoscopically displaying the picture  41 , and other data and programs, a random access memory (hereinafter, also referred to as RAM)  52  for accepting temporarily the application program and other data and programs stored in the HDD  51 , an interface for USB  53  for performing the data transmission with the aforesaid digital camera  2 , an interface for an IC card  54  for reading out the data stored in the IC card  8 , the display  55  for displaying a picture, a video random access memory (hereinafter, also referred to as VRAM)  56  for making a picture be displayed on the display  55 , the input unit  57  composed of the keyboard  57   a  and the mouse  57   b  for inputting a command for making an application program be executed, a compressing/expanding section  58  for expanding data of the JPEG format and compressing data in the JPEG format, and a microprocessor unit (hereinafter, also referred to as MPU)  59  for controlling the whole of the controlling unit  3 .  
     [0069] In the HDD  51 , there are stored an operating system (hereinafter, also referred to as OS), an editing program for editing the picture  41  composed of the picture for a right eye  41   a  and the picture for a left eye  41   b , a browsing software for browsing the picture edited by the editing program, the picture data of the picture  41  composed of the picture for a right eye  41   a  and the picture for a left eye  41   b , and other data and programs.  
     [0070] The RAM  52  accepts an application program to be executed and data of a picture to be processed from the HDD  51  and other units. For example, the picking up processing of the picture data of the picture  41  for picking up the picture data of a picture for a right eye and the picture data of a picture for a left eye from the unit picture data of the picture  41  composed of the picture for a right eye  41   a  and the picture for a left eye  41   b  for the displaying of them on the display  55  is executed at the RAM  52 .  
     [0071] The interface for USB  53  receives the picture data compressed in the JPEG format by the digital camera  2  when the interface for USB  53  is connected with the interface for USB  18  of the digital camera  2  with an USB format. Then, the picture data received by the interface for USB  53  is stored in the HDD  51  by the MPU  59 .  
     [0072] The interface for an IC card  54  reads out the picture data, which is stored in the IC card  8 , of a picture photographed by, for example, the digital camera  2  when the IC card  8  is loaded on the drive for the IC card  8  that is formed in the main body of the controlling unit  3 . Then, the picture data read out by the interface for USB  53  is stored in the HDD  51  by the MPU  59 .  
     [0073] The display  55  is constituted of a CRT or a liquid crystal display panel, and the display  55  displays the picture  41  composed of the picture for a right eye  41   a  and the picture for a left eye  41   b  located side by side in the horizontal direction as shown in FIG. 5 before the edit processing is performed. Moreover, the display  55  displays a picked up picture for a right eye and a picked up picture for a left eye alternately with a parallax on the basis of the picked up picture data for a right eye and the picked up picture data for a left eye, both having been processed by the picking up processing of the picture data of the picture for a right eye  41   a  and the picture for a left eye  41   b . Incidentally, the display  55  may be either of one performing its displaying in conformity with the progressive scanning system or one performing its displaying in conformity with the interlace scanning system.  
     [0074] The VRAM  56  for displaying an picture on the display  55  has memory sections  56   a  and  56   b , each having a capacity necessary for storing picked up picture data of one frame. For example, the picked up picture data for a right eye of one frame is stored in the memory section  56   a , and the picked up picture data for a left eye of one frame is stored in the memory section  56   b . Then, the VRAM  56  alternately outputs the picked up picture data for a right eye stored in the memory section  56   a  and the picked up picture data for a left eye stored in the memory section  56   b  to the display  55 .  
     [0075] When the picture data stored in, for example, the IC card  8  and compressed in the JPEG format is read out to the RAM  52 , the compressing/expanding section  58  expands the compressed picture data. Moreover, when edited picture data is preserved, the compressing/expanding section  58  compresses the picture data in the RAM  56  into the JPEG format and stores it in the HDD  51  or in the IC card  8 .  
     [0076] The MPU  59  controls the whole of the controlling unit  3 . For example, the MPU  59  stores picture data that is read out by the interface for USB  53  or by the interface for an IC card  54  into the HDD  51 . Moreover, the MPU  59  reads out an editing program for editing the picture  41  composed of the picture for a right eye  41   a  and the picture for a left eye  41   b , a browsing software for browsing the picture edited by the editing program, and picture data to be processed by these programs to the RAM  52  from the HDD  51 . Then, the MPU  59  performs the picking up processing for picking up the picture data of a picture for a right eye and the picture data of a picture for a left eye for displaying on the display  55  from the unit picture data, and makes the RAM  52  output the processed picked up picture data for a right eye to the memory section  56   a  of the VRAM  56 , and makes the RAM  52  output the processed picked up picture data for a left eye to the memory section  56   b  of the VRAM  56 .  
     [0077] When the picked up pictures composed of the picked up picture for a right eye and the picked up picture for a left eye are displayed on the display  55 , the controlling unit  3  described above operates as follows. That is, the MPU  59  expands the picture data composed of the picture data for a right eye and the picture data for a left eye that is compressed in the JPEG format and read out from the HDD  51  and other memories, and then the MPU  59  reads out the expanded picture data to the RAM  52 . Then, the MPU  59  picks up prescribed regions of the picture for a right eye  41   a  and the picture for a left eye  41   b  shown in FIG. 5 on the basis of a command output from the input unit  7  operated by an user. The MPU  59  then outputs the picked up picture data for a right eye to the memory section  56   a  constituting the VRAM  56 , and outputs the picked up picture data for a left eye to the memory section  56   b  constituting the VRAM  56 . Next, the VRAM  56  alternately outputs the picked up picture data for a right eye from the memory section  56   a  and outputs the picked up picture data for a left eye from the memory section  56   b . Here, each picked up picture data is output to the display  55  adopting the system in which all of the scan lines are sequentially drawn, i.e. the progressive scanning system. The picked up picture for a right eye and the picked up picture for a left eye are alternately displayed on the display  55  to enable an user wearing the shutter spectacles  4  to stereoscopically look at the picture displayed on the display  55 .  
     [0078] Now, when the picture for a right eye and the picture for a left eye are displayed on the display  55  adopting the progressive scanning system, as shown in FIGS. 1 and 6, the picked up picture data for a right eye of one frame and the picked up picture data for a left eye of one frame are read out from the memory sections  56   a  and  56   b  of the VRAM  56 , and the picked up picture for a right eye and the picked up picture for a left eye are displayed alternately. It is necessary for the shutter spectacles  4  to switch the shutters of the shutter section for a right eye  4   a  and the shutter section for a left eye  4   b  synchronously with the switching of the display of the picked up picture for a right eye and the picked up picture for a left eye. Accordingly, the controlling unit for spectacles  6  for controlling the shutter spectacles  4  is provided between the display  55  and the VRAM  56 .  
     [0079] The controlling unit for spectacles  6  comprises, as shown in FIG. 7, a detecting section  61  for detecting the vertical synchronizing signal of each picture data when the picked up picture data for a right eye of one frame and the picked up picture data for a left eye of one frame that are stored in the memory sections  56   a  and  56   b  of the VRAM  56 , respectively, are output to the display  55 , and a switch  64  the center contact of which is connected with the detecting section  61  and one of the switching contacts of which is connected with a terminal  62  of the shutter section for the right eye  4   a  of the shutter spectacles  4  and further the other switching contact of which is connected with the terminal  63  of the shutter section for the left eye  4   b  of the shutter spectacles  4 .  
     [0080] As shown in FIG. 8A, when the picked up picture data for a right eye and the picked up picture data for a left eye are alternately output from the VRAM  56  to the display  55 , the detecting section  61  detects the vertical synchronizing signal of each picked up picture data. For example, when the picked up picture data for a right eye is output from the memory section  56   a  of the VRAM  56 , the detecting section  61  detects the vertical synchronizing signal of the picked up picture data. Detecting the vertical synchronizing signal of the picked up picture data for a right eye, the detecting section  61  switches the switch  64  so as to turn off the shutter section for the left eye  4   b  of the shutter spectacles  4  as shown in FIG. 8B so that an user can observe the picked up picture for a left eye that is to be displayed subsequently with the left eye of the user, and so as to turn on the shutter section  4   a  for the right eye as shown in FIG. 8C. When a picked up picture for a left eye is displayed on the display  55 , the shutter section for the left eye  4   b  takes thereby the open state and the shutter section for the right eye  4   a  takes the closing state.  
     [0081] Successively, when the detecting section  61  detects the vertical synchronization signal of the picked up picture data for a left eye that is now displayed, as shown in FIG. 8C, the detecting section  61  switches the switch  64  so as to turn off the shutter section for the right eye  4   a  of the shutter spectacles  4  for enabling the user to observe the picked up picture for a right eye that is to be displayed subsequently with the right eye of the user, and, as shown in FIG. 8B, so as to turn on the shutter section for left eye  4   b . Consequently, when the picked up picture for a right eye is displayed on the display  55 , the shutter section for the right eye  4   a  takes a open state and the shutter section for the left eyes takes a closing state. Hereafter, the switching of the shutters of the shutter section for the right eye  4   a  and the shutter section for the left eye  4   b  of the shutter spectacles  4  is performed synchronously with the timing of the switching of the picked up picture for a right eye and the picked up picture for a left eye, and consequently the user can observe the pictures displayed on the display  55  stereoscopically.  
     [0082] In the case where the display  55  displaying pictures in conformity with the interlace scanning system is used will next be described. In the aforesaid memory  56   a  of the VRAM  56 , the horizontal scan line data of the picked up picture for a right eye are stored by one line, for example, the picked up picture data for a right eye formed by the thinning out of the even line data from the whole of the picked up picture data for a right eye of one frame are stored. Similarly, in the aforesaid memory  56   b  of the VRAM  56 , the horizontal scan line data of the picked up picture for a left eye are stored by one line, for example, the picked up picture data for a left eye formed by the thinning out of the odd line data from the whole of the data of the picked up picture data for a left eye of one frame are stored. Then, the thinned out picked up picture data for a right eye is output from the memory  56   a  to the display  55  as the picture data of one field, and the thinned out picked up picture data for a left eye is output from the memory  56   b  to the display  55  as the picture data of the next field. Consequently, the picture formed by the thinning out of even lines is first displayed on the display  55 , and then the picture formed by the thinning out of odd lines is next displayed on the display  55  as shown in FIG. 9A.  
     [0083] At this time, the controlling unit for spectacles  6  controls the shutter spectacles  4  as follows. That is, as shown in FIG. 9B, when the picked up picture data for a right eye for the first field is output from the memory  56   a , the detecting section  61  detects the vertical synchronizing signal located at the end of the field. Detecting the vertical synchronizing signal of the picked up picture data for a right eye, the detecting section  61  switches the switch  64  so that the shutter section for the left eye  4   b  of the shutter spectacles  4  is turned off for enabling an user to observe the picked up picture for a left eye that is to be displayed subsequently with the left eye of the user as shown in FIG. 9C and the shutter section for the right eye  4   a  is turned on as shown in FIG. 9D. When a picked up picture for a left eye is displayed on the display  55 , the shutter section for the left eye  4   b  consequently takes a state of open and the shutter section for the right eye  4   a  takes a state of closing.  
     [0084] Next, when the detecting section  61  detects the vertical synchronization signal of the picked up picture data for a left eye that is now displayed as shown in FIG. 9B, the detecting section  61  switches the switch  64  so that the shutter section for the right eye  4   a  of the shutter spectacles  4  is turned off for enabling the user to observe the picked up picture for a right eye to be displayed next with the right eye of the user as shown in FIG. 9D and the shutter section for the left eye  4   b  is turned on as shown in FIG. 9C. When a picked up picture for a right eye is displayed on the display  55 , the shutter section for the right eye  4   a  consequently takes the state of open and the shutter section for the left eye  4   b  takes the state of closing. Hereafter, the switching of the shutters of the shutter section for the right eye  4   a  and the shutter section for the left eye  4   b  of the shutter spectacles  4  is thus performed synchronously with the timing of the switching of the picked up picture for a right eye and the picked up picture for a left eye, and consequently an user can observe the pictures displayed on the display  55  stereoscopically.  
     [0085] Incidentally, in the case where the progressive scanning system is adopted, the picked up picture data for a right eye formed by the thinning out of, for example, even lines may be stored in the memory section  56   a  and the picked up picture data for a left eye formed by the thinning out of odd lines may be stored in the memory section  56   b  as described above. In this case, similarly to in the interlace scanning system, a picked up picture for a right eye formed by the thinning out of even lines and a picked up picture formed by the thinning out of odd lines are alternately displayed on the display  55 . Incidentally, when the picked up picture data for a right eye and the picked up picture data for a left eye, horizontal lines of both pictures being thinned out, are output to the VRAM  56 , because a CCD element having several millions of pixels is used as the CCD element  12  of the digital camera  2  as described above, the user does not feel the deterioration of the picture quality of the displayed pictures.  
     [0086] Next, the processing using the aforesaid controlling unit  3  of the picture data of a picture photographed by the aforesaid digital camera  2  with the attached adapter  5 , namely the edit processing of the picture data will be described by reference to FIG. 10.  
     [0087] At first, at step S 1 , when an icon for activating the editing program displayed on the display  55  is clicked with the mouse  57   b  for example, the MPU  59  reads out the editing program from the HDD  51  to the RAM  52  for activating it, and the edit processing advances to step S 2 .  
     [0088] In the step S 2 , the MPU  59  selects a file of the picture data to be edited on the basis of a command from the input unit  57  composed of the keyboard  57   a  and the mouse  57   b , and opens the selected files. Here, the picture data constitutes a file compressed in the JPEG format. To put it concretely, the MPU  59  reads out the corresponding file from the memory  17  of the digital camera  2  to the RAM  52  after expanding the file with the compressing/expanding section  58  when the digital camera  2  and the controlling unit  3  are connected with each other with an USB interface. Moreover, when the IC card  8  is mounted on the drive of the controlling unit  3 , the MPU  59  reads out the corresponding file from the IC card  8  to the RAM  52  after expanding the file by the compressing/expanding section  58 . And when the corresponding file is stored in the HDD  51 , the MPU  59  reads out the file from the HDD  51  to the RAM  58  after expanding it by the compressing/expanding section  58 . And then the edit processing advances to step S 3 .  
     [0089] At the step S 3 , the MPU  59  outputs the read out picture data stored in the RAM  52  temporarily to the display  55  adopting the progressive scanning system or the interlace scanning system through the VRAM  56  to make the display  55  displays a picture based on the picture data. And then, the edit processing advances to step S 4 . At the step S 3 , the picture  41  shown in the aforesaid FIG. 5 is displayed on the display  55 . That is, the picture for a right eye  41   a  and the picture for a left eye  41   b  are displayed as one picture  41  on the display  55  abreast in the horizontal direction. And, the picture for a right eye  41   a  and the picture for a left eye  41   b  are shifted by the parallax on the right side and the left side. Incidentally, the boundary part  42  between the picture for a right eye  41   a  and the picture for a left eye  41   b  is displayed as the rather blurred white line.  
     [0090] At the step S 4 , the MPU  59  displays a division line  71  to divide the picture  41  into the picture for a right eye  41   a  and the picture for a left eye  41   b  in the vertical direction of the display  55  as shown in FIG. 11A. Then, the division line  71  is held by the pointer  72  when the mouse  57   b  is clicked, and is moved to overlap on the boundary part  42  of the picture  41  by an user watching it. The MPU  59  thereby divides the picture  41  into the picture for a right eye  41   a  and the picture for a left eye  41   b . Consequently, the user can discern the picture for a right eye  41   a  and the picture for a left eye  41   b  easily.  
     [0091] At step S 5 , the MPU  59  makes the display  55  display a vertical center line  73   a  for the picture for a right eye  41   a  and a vertical center line  73   b  for the picture for a left eye  41   b  as shown in FIG. 11B for making the horizontal centers of the picture for a right eye  41   a  and the picture for a left eye  41   b  divided at the division line  71  displayed on the display  55  easily looked at. Here, the MPU  59  makes the display  55  display the vertical center line  73   a  for the picture for a right eye  41   a  and the vertical centerline  73   b  for the picture for a left eye  41   b  so that they are at the same distance from the division line  71 . Then, the vertical center line  73   a  for the picture for a right eye  41   a  is held by the pointer  72  when the mouse  57   b  is clicked, and is moved to a horizontal center position that is desired by the user in the horizontal direction by the user watching it. At the same time, the vertical center line  73   b  for the picture for a left eye  41   b  is automatically moved to the same direction as that of the movement of the vertical center line  73   a  for the picture for a right eye  41   a  by the same quantity of movement as that of the center line  73   a . Thus the MPU  59  makes it easy for the user to look at the horizontal center of the picture for a right eye  41   a  and the horizontal center of the picture for a left eye  41   b  so that the set vertical center lines  73   a  and  73   b  can be guideposts for picking up operation of the picture for a right eye  41   a  and the picture for a left eye  41   b  at the nest step.  
     [0092] At step S 6 , the MPU  59  makes the display  55  display a horizontal center line  74  for makes it easy to look at the center in the vertical direction of the picture for a right eye  41   a  and the picture for a left eye  41   b  divided at the division line  71  displayed on the display  55  as shown in FIG. 1C. Here, the MPU  59  makes the display  55  display the horizontal center line  74  over the picture for a right eye  41   a  and the picture for a left eye  41   b  at the center in the vertical direction. Then, the horizontal center line  74  is held by the pointer  72  when the mouse  57   b  is clicked, and is vertically moved to a position that the user desires as the center in the vertical direction by the user while the user watches the horizontal center line  74  with eyes. The MPU  59  thereby makes it easy for the user to look at the vertical center of the picture for a right eye  41   a  and the picture for a left eye  41   b , and further makes center points  75   a  and  75   b  of the picture for a right eye  41   a  and the picture for a left eye  41   b , respectively, easy to determinate with the aforesaid center lines  73   a  and  73   b , respectively, so that the center points  75   a  and  75   b  can be guideposts for picking up operation of the picture for a right eye  41   a  and the picture for a left eye  41   b  at the next step.  
     [0093] Incidentally, the center points  75   a  and  75   b  can also be readjusted. That is, the adjustment of the vertical center lines  73   a  and  73   b  can be performed by the re-displacement of the center line  73   a  for the picture for a right eye  41   a  in the horizontal direction as shown in FIG. 11B, and the adjustment of the horizontal center line  74  can be performed by the displacement of the horizontal center line  74  in the vertical direction as shown in FIG. 1C.  
     [0094] At step S 7 , the MPU  59  executes the picking up processing of a picture that the user desires. To put it concretely, when the user determines a starting point  76  in the picture for a right eye  41   a  with the pointer  72  of the mouse  57   b  by reference to the aforesaid vertical center line  73   a , the horizontal center line  74  and the center point  75   a , and when the user moves the pointer  72  in a diagonal direction, a substantially rectangular picked up line  77   a  is displayed in the picture for a right eye  41   a  as shown in FIG. 1D. At the same time, the MPU  59  makes the display  55  display a picked up line  77   b  having the same shape as the picked up line  77   a  in the picture for a left eye  41   b , too. At this time, the MPU  59  makes the display  55  display the picked up line  77   b  so that the distance between the division line  71  and the line of the picked up line  77   a  on the side of the division line  71  becomes equal to the distance between the side edge of the picture for a left eye  41   b  on the side farther from the division line  71  and the line of the picked up line  77   b  on the side of the side edge.  
     [0095] Thus, the MPU  59  generates the picture data of the picked up picture for a right eye  78   a  and the picture data of the picked up picture for a left eye  78   b  for stereoscopically displaying a picture on the display  55 . By the way, there is a case where the user wants to look at how the picture is displayed on the display  55  stereoscopically before the user stores the picture data of the thus actually picked up picture to the HDD  51 . Accordingly, at step S 8 , the MPU  59  outputs the picture data of the picked up picture for a right eye  78   a  and the picture data of the picked up picture for a left eye  78   b  to the VRAM  56 , and activates a preview mode. Incidentally, the preview mode will be described in detail later. Then, at step S 9 , the MPU  59  stores the picture data of the picture for a right eye  78   a  and the picture data of the picture of the left eye  78   b  in the HDD  51  after compressing them in the compressing/expanding section  58  in the JPEG format. Incidentally, the details of the storing method will also be described later.  
     [0096] In the aforesaid edit processing method of the picture data, a stereoscopic picture suitable for the user&#39;s taste can be displayed on the display  55  by picking up a region in the picture  41  that the use desires. Moreover, when the picture data of the picture  41  is edited, because the vertical center lines  73   a  and  73   b  and the horizontal center line  74  are displayed on the display  55 , the user can easily perform the picking up operation of the picture  41 .  
     [0097] Incidentally, because the editing operation of the picture  41  is performed by the use of the picture for a right eye  41   a , only the picture for a right eye  41   a  for the editing operation may be displayed on the display  55  while the boundary part  42  is set to be automatically recognized by the MPU  59 .  
     [0098] Next, the preview mode at the aforesaid step S 8  will be described by reference to FIG. 12. At step S 11 , the MPU  59  activates the preview mode on the basis of a command from the input unit  57 .  
     [0099] At step S 12 , the MPU  59  makes the display  55  display a selection screen of a display form. Now, there are following forms for the display of a stereoscopic picture: a substantially rectangular frame  79   a  having an aspect ratio of  3  to  4  as shown in FIG. 13A, a substantially rectangular frame  79   b  having an aspect ratio of 9 to 16 as shown in FIG. 13B, and a substantially circular frame  79   c  as shown in FIG. 13C. Then, the MPU  59  selects any one of the frames  79   a - 79   c  shown by FIGS. 13A to  13 C, respectively, on the basis of a command from the input unit  57  generated by the operation of the user, and the preview mode advances to step S 13 .  
     [0100] At the step S 13 , the MPU  59  determines the outputting order of the picture data of the picked up picture for a right eye  78   a  and the picture data of the picked up picture for a left eye  78   b  from the VRAM  56  on the basis of an input signal from the input unit  57  by the operation of the user. To put it concretely, the outputting order indicates which picture of the picked up pictures for the right eye  78   a  and for the left eye  78   b  is first displayed on the display  55 .  
     [0101] At step S 14 , the MPU  59  makes the display  55  display the picked up picture for a right eye  78   a  and the picked up picture for a left eye  78   b  alternately so as to have a parallax. To put it concretely, the MPU  59  outputs the picture data of the picked up picture for a right eye  78   a  to the memory section  56   a  of the VRAM  56 , and outputs the picture date of the picked up picture for a left eye  78   b  to the memory section  56   b  of the VRAM  56 . Then, the VRAM  56  alternately outputs the picture data of the picture for a right eye  78   a  and the picture data of the picture for a left eye  78   b  to the display  55  in conformity with the outputting order determined at the step S 13  so that the display  55  displays the picked up picture for a right eye  78   a  and the picked up picture for a left eye  78   b  alternately.  
     [0102] As a result, the picked up picture for a right eye  78   a  and the picked up picture for a left eye  78   b  are displayed on the display  55  as if they are shifted from each other as shown in FIGS. 14A and 14B. To put it concretely, the picked up picture for a right eye  78   a  and the picked up picture for a left eye  78   b  displayed on the display  55  are displayed so that the amount of shifting becomes zero at the position of the visual point of the user and the amount of the shifting becomes larger from the position of zero to the front direction or the rear direction viewed at the standpoint of the user. Incidentally, the position where the amount of shifting is zero is hereinafter referred to as a cross point  81 . That is, if the position where a person is standing in FIG. 14A is supposed to the cross point  81 , the mountain is displayed so as to shift to a direction because it is located at a rear place to the person&#39;s position, and the flower is displayed so as to shift to another direction because it is located at a front position to the person&#39;s position.  
     [0103] Moreover, as described above, the controlling unit for spectacles  6  performs the switching of the shutters of the shutter section for the right eye  4   a  and the shutter section for the left eye  4   b  in accordance with the outputting order of the picture data at the step S 13 . At the time of the switching, the controlling unit for spectacles  6  detects the vertical synchronization signals of the picture data of the picked up picture for a right eye  78   a  and the picture data of the picked up picture for a left eye  78   b  by the detecting section  61 , and performs the switching of the shutters of the shutter section for the right eye  4   a  and the shutter section for the left eye  4   b  synchronously with the timing of switching of the picked up picture for a right eye  78   a  and the picked up picture for a left eye  78   b  displayed on the display  55 . Thereby, the user can stereoscopically look at the picture displayed on the display  55 . At the following steps, the user performs the preview mode processing in a state that the user wears the shutter spectacles  4 .  
     [0104] At step S 15 , depth adjustment, i.e. the adjustment of the cross point  81 , is performed for making it easiest for the user to look at the stereoscopic picture. That is, the MPU  59  makes the display  55  display adjustment buttons  83 ,  84  to adjust the cross point  81  on the screen  82  shown in FIG. 14A. Now, the adjustment button  83  is for moving the cross point  81  to the front direction on the screen  82 , i.e. for moving it horizontally to one direction, and the adjustment button  84  is for moving the cross point  81  to the rear direction, i.e. for moving it horizontally to another direction. Because these adjustment buttons  83  and  84  are for moving the cross point  81  in the horizontal direction, these adjustment buttons  83  and  84  are displayed on the screen  82  side by side in the horizontal direction for making the operation of them to be easy.  
     [0105] When the user pushes the adjustment button  83  with the input unit  57 , the MPU  59  moves the cross point  81  to the front direction, i.e. to the lower left direction on the screen  82  of FIG. 14A. Then, when the cross point  81  has moved to the position of the flower for example, the positions of the persons in the picked up picture for a right eye  78   a  and the picked up picture for a left eye  78   b  are displayed on the display  55  as if they are shifted to one direction, and the positions of the mountains in the pictures are displayed on the display  55  as if they are more shifted to the same direction. The user wearing the shutter spectacles  4  consequently sees the pictures as if the person is located at the rear of the flower as a reference position and the mountain is located at the further rear of the person. Moreover, when the user pushes the adjustment button  84  with the input unit  57 , the MPU  59  moves the cross point  81  to the rear direction, i.e. to the upper right direction on the screen  82  of FIG. 14A. Then, when the cross point  81  has moved to the position of the mountain for example, the positions of the persons in the picked up picture for a right eye  78   a  and the picked up picture for a left eye  78   b  are displayed on the display  55  as if they are shifted to another direction, and the positions of the flowers in the pictures are displayed on the display  55  as if they are more shifted to the same direction. The user consequently sees the pictures as if the person is located at the front of the mountain as a reference position and the flower is located at the further front of the person. The user can thus adjust the depth of the picture, i.e. the cross point  81 , at the position where it is easiest for the user to look at the stereoscopic picture.  
     [0106] At step S 16 , the adjustment of the picture in the vertical direction is performed for making it easiest for the user to look at the stereoscopic picture. That is, when photographing is performed with the digital camera  2  with the attached adapter  5 , there is a case where the adapter  5  is attached to the digital camera  2  in an inclined state and the photographed picture  41  shown in FIG. 5 is also inclined. It is difficult to see such an inclined picture  41  stereoscopically. Accordingly, at the step S 16 , the MPU  59  makes the display  55  display adjustment buttons  85  and  86  on the screen  82  for adjusting the picked up picture for a right eye  78   a  and the picked up picture for a left eye  78   b  in the vertical direction. When the user pushes the adjustment button  85  with the input device  57 , the MPU  59  shifts the picking up picture for a right eye  78   a  to the upper side, and shifts the picked up picture for a left eye  78   b  to the lower side on the screen  82 . Moreover, when the user pushes the adjustment button  86  with the input device  57 , the MPU  59  shifts the picked up picture for a right eye  78   a  to the lower side, and shifts the picked up picture for a left eye  78   b  to the upper side on the screen  82 . The user can thus adjust the vertical positions of the picked up picture for a right eye  78   a  and the picked up picture for a left eye  78   b  to the positions where it is easiest for the user to look at a stereoscopic picture. Incidentally, because the adjustment buttons  85  and  86  are for making the pictures move in the vertical direction, the adjustment buttons  85  and  86  are displayed on the screen  82  side by side in the vertical direction.  
     [0107] In the aforesaid preview mode, because the depth of the picture, or the cross point  81 , can be adjusted with the adjustment buttons  83  and  84  displayed on the screen  82 , and because the displayed positions of the picked up picture for a right eye  78   a  and the picked up picture for a left eye  78   b  can vertically be adjusted with the adjustment buttons  85  and  86  displayed on the screen  82 , it is possible to store the picked up picture for a right eye  78   a  and the picked up picture for a left eye picture  78   b  into the HDD  51  after the adjustment of their states so that a stereoscopic picture become easiest for the user to look at.  
     [0108] Now, as shown in FIG. 15, there is a case where, for example, the pointer  72  by the mouse  57   b  constituting the input unit  57  is moved on the stereoscopic picture  78  composed of the picked up picture for a right eye  78   a  and the picked up picture for a left eye  78   b  that are alternatively displayed in the aforesaid preview mode. When the pointer  72  is displayed two-dimensionally, i.e. in the display state at the cross point  81  in this case, it becomes hard for an user to look at the pointer  72 . Accordingly, the MPU  59  makes the display  55  shift the displayed pointer  72  in accordance with the parallax at the position of the pointer  72  on the stereoscopic picture, i.e. the amount of the shift between the picked up picture for a right eye  78   a  and the picked up picture for a left eye  78   b . That is, when the cross point  81  is situated at the person and the pointer  72  is situated near to the mountain at a rear position in the stereoscopic picture  78  as shown in FIG. 15, the MPU  59  makes the display  55  display the pointer  72  to be shifted in accordance with the amount of the shift between the picked up picture for a right eye  78   a  and the picked up picture for a left eye  78   b  at this position. Moreover, when the pointer  72  is situated near to the flower at a front position in the stereoscopic picture  78 , the MPU  59  makes the display  55  display the pointer  72  to be shifted in accordance with the amount of the shift between the picked up picture for a right eye  78   a  and the picked up picture for a left eye  78   b  at this position. Moreover, when the pointer  72  is situated at the cross point  81 , the MPU  59  makes the display  55  display the pointer  72  flatwise without shifting it, because there is no shift between the picked up picture for a right eye  78   a  and the picked up picture for a left eye  78   b . Thereby, because the user can stereoscopically look at the pointer  72  that is always displayed in accordance with the parallax of the picture existing as a background when the pointer  72  moves on the stereoscopic picture  78  displayed stereoscopically, it can be prevented that it becomes hard for the user to look at the pointer  72 .  
     [0109] Moreover, as shown in FIG. 15, a character  87  can be input into the picture  41  when the picture  41  is edited. That is, when a position where the character  87  is input in the stereoscopic picture  78  by the pointer  72  by the mouse  57   b  and a character (e.g. “A”) is input with the keyboard  57   a , the MPU  59  makes the display  55  display the character  87  at the designated position in the stereoscopic picture  78 . At this time, the MPU  59  makes the display  55  display the character  87  in accordance with the parallax at the coordinates on the stereoscopic picture  78  where the character  87  is input, i.e. the amount of the shift between the picked up picture for a right eye  78   a  and the picked up picture for a left eye  78   b . That is, when the cross point  81  is situated at the person and the character  87  is displayed near to the mountain located at a rear position in the stereoscopic picture  78 , the MPU  59  makes the display  55  display the character  87  to be shifted in accordance with the amount of the shift between the picked up picture for a right eye  78   a  and the picked up picture for a left eye  78   b  at the position. Moreover, when the character  87  is situated near to the flower at a front position in the stereoscopic picture  78 , the MPU  59  makes the display  55  display the character to be shifted in accordance with the amount of the shift between the picked up picture for a right eye  78   a  and the picked up picture for a left eye  78   b  at the position. Moreover, when the character  87  is displayed at the cross point  81 , the MPU  59  makes the display  55  display character  87  flatwise without shifting it, because there is no shift between the picked up picture for a right eye  78   a  and the picked up picture for a left eye  78   b . Thereby, because the user can stereoscopically look at the character  87  that is always displayed in accordance with the parallax of the picture existing as a background when the character  87  is displayed on the stereoscopic picture  78  displayed stereoscopically, it can be prevented that it becomes hard for the user to look at the character  87 . Moreover, when the amount of the shift of the character  87  is adjusted to the amount of the shift at the most front position in the picture  78 , the character  87  seems for the user to be at the most front position, and thereby the character  87  can be emphasized.  
     [0110] Moreover, when the picked up picture for a right eye  78   a  and the picked up picture for a left eye  78   b  are alternately displayed as shown in FIG. 14A, the surface to be a reference is the screen  82  of the display  55  or the frames  79   a  to  79   c  shown in FIG. 13A to  13 C, respectively. That is, the screen  82  and the frames  79   a  to  79   c  on the screen  82  are displayed in a flatwise display form in which the parallax is not considered. Consequently, because the perimeter of the stereoscopic picture  78  displayed on the screen  82  is displayed flatwise, it becomes hard for the user, who wears the shutter spectacles  4  and are looking at the stereoscopic picture  78  of FIG. 14A, to look at the stereoscopic picture  78  stereoscopically. Accordingly, a frame body  88  having a prescribed width, for example, a casing, is displayed around the stereoscopic picture  78  as shown in FIG. 16. When the amount of the shift of the frame body  88  is set to be the same as that of an object displayed at the most front position, e.g. the flower, it becomes possible to show the stereoscopic picture  78  to the user as if the stereoscopic picture  78  is stereoscopically displayed on the inside of the frame body  88 . Moreover, when the amount of the shift of the frame body  88  is set to be the same as that of an object displayed at the most rear position, e.g. the mountain, it becomes possible to show the stereoscopic picture  78  to the user as if the stereoscopic picture  78  itself is protruded out of the frame body  88 . By the provision of the frame body  88  with the prescribed width around the stereoscopic picture  78  in such a way, it is possible to make it easier for the user to look at the stereoscopic picture.  
     [0111] Next, the management method of the thus edited picture data of the stereoscopic picture  78  composed of the picture data of the picked up picture for a right eye  78   a  and the picture data of the picked up picture for a left eye  78   b , namely the data management method at the step S 9  in the aforesaid FIG. 10, will be described by reference to FIG. 17. When the picture data of the picked up picture for a right eye  78   a  and the picture data of the picked up picture for a left eye  78   b , both picked up pictures being shown in FIG. 14A, are stored, a save button  89  displayed on the screen  82  is first pushed with the mouse  57   b  of the input unit  57  or other devices. When the save button  89  is pushed by the pointer  72 , the MPU  59  stores the picture data of the picked up picture for a right eye  78   a  and the picture data of the picked up picture for a left eye  78   b  on the RAM  52  into the HDD  51  or the IC card  8  through a bus. To put it more concretely, as shown in FIG. 17, the MPU  59  stores a data file of picked up pictures for a right eye  92 , a data file of picked up pictures for a left eye  93  and an information file  94  which consists of the information relating to the files  92  and  93  into a folder  91 .  
     [0112] The data file of picked up pictures for a right eye  92  is a data file of the picture data of the picked up pictures for a right eye  78   a  picked up at the step S 7  in FIG. 10, and the picture data have compressed in the JPEG system by the compressing/expanding section  58 . Moreover, the data file of picked up pictures for a left eye  93  is a data file of the picture data of the picked up pictures for a left eye  78   b , and the picture data have compressed in the JPEG system by the compressing/expanding section  58 .  
     [0113] The coordinates of the cross point  81  when the picked up picture for a right eye  78   a  and the picked up picture for a left eye  78   b  are alternately displayed are stored in the information file  94 . Moreover, as described above, when the picked up picture for a right eye the even lines of which have been thinned out and the picked up picture for a left eye the odd lines of which have been thinned out are displayed on the display  55 , the line information indicating which of the pictures the first line of a picture to be displayed is included in is stored. That is, the information file  94  includes the data necessary to reproduce a stereoscopic picture at the time when the stereoscopic picture is stored.  
     [0114] Because the data file of picked up pictures of a right eye  92 , the data file of picked up pictures of a left eye  93 , and the information file  94  are separately provided in the aforesaid data management method, these data can be re-edited even if these data are compressed and expanded. That is, because the folder  91  includes the data file of cut put pictures for a right eye  92  and the data file of picked up pictures for a left eye  93 , the user can perform the re-editing such as the expansion or compression of the picked up picture for a right eye  78   a  and the picked up picture for a left eye  78   b .  
     [0115] Moreover, the picture data of the picked up pictures for the right eye  78   a  and the picture data of the picked up pictures for the left eye  78   b  can also be stored as shown in FIG. 18. That is, there are stored in the folder  96  a picture data file  97  including the picture data of the picture  41  composed of the picture for a right eye  41   a  and the picture for a left eye  41   b  as shown in FIG. 5 and an information file  98  composed of the information for generating the picked up picture for a right eye  78   a  and the picked up picture for a left eye  78   b  from the picture data file  97 . That is, the picture data file  97  is a file including the picture data compressed in the JPEG format by the compressing/expanding section  58  before the edit processing shown in FIG. 10. Moreover, there are stored in the information file  98  the position data of the division line  71 , the position data of the vertical center lines  73   a  and  73  b, the position data of the horizontal center line  74 , and the position data of the picked up lines  77   a  and  77   b , all of the lines  71 ,  73   a ,  73   b ,  74 ,  77   a  and  77   b  being shown in FIG. 1D. Moreover, the coordinates of the cross point  81  when the picked up picture for a right eye  78   a  and the picked up picture for a left eye  78   b  are alternately displayed are stored in the information file  96 . Moreover, when a picked up picture for a right eye formed by the thinning out of even lines from a picked up picture for a right eye of one frame and a picked up picture for a left eye formed by the thinning out of odd lines from a picked up picture for a left eye of one frame are displayed on the display  55 , the line information indicating which of the pictures the first line of a picture to be displayed is included in is stored. That is, the information file  98  includes the data necessary to reproduce a stereoscopic picture at the time when the stereoscopic picture is stored.  
     [0116] Because the picture data of the picture  41  composed of the picture for a right eye  41   a  and the picture for a left eye  41   b  are preserved in the aforesaid data management method, more editorial operations can be performed in comparison with the storing method shown in FIG. 17 even if the picture data are compressed and expanded. To put it concretely, in the management method, the picture data file  97  and the information data file  98 , both being stored in the folder  96 , are read out from the folder  96 , and the re-editing operation of a picture, for example, the editing operation such as the picked up of a picture as shown in FIG. 10 and FIG. 11, can be performed on the basis of the data in the read out files  97  and  98 .  
     [0117] Moreover, the picture data of the picked up picture for a right eye  78   a  and the picture data of the picked up picture for a left eye  78   b  can also be stored as follows. That is, the storing method is a method for storing synthesized picture data composed of the data on the horizontal scan lines of the picture data of the picked up picture for a right eye  78   a  and the data on the horizontal scan lines of the picture data of the picked up picture for a left eye  78   b , both of the data being alternatively taken into the synthesized picture data. As shown in FIG. 19, there is stored in a folder  101  a synthesized picture data file  102  in which the synthesized picture data formed by the synthesis of the picture data of a picked up picture for a right eye formed by the thinning out of even lines from a picked up picture for a right eye of one frame and the picture data of a picked up picture for a left eye formed by the thinning out of odd lines from a picked up picture for a left eye of one frame.  
     [0118] Because any information file is not provided in such a management method in comparison with the management methods of picture data shown in FIG. 17 and FIG. 18, the re-editing cannot be performed but the data size can be reduced. Incidentally, there may be stored in the folder  101  the data file of picked up pictures for a right eye  92 , the data file of picked up pictures for a left eye  93 , and the information file  94  including the information relating to the these files  92  and  93 , all of the files  92 ,  93  and  94  being shown in FIG. 17, in addition to the synthesized picture data file  102 . Moreover, there may be stored in the folder  101  the picture data file  97  including the picture data of the picture  41  composed of the picture for a right eye  41   a  and the picture for a left eye  41   b  and the information file  98  including the information for generating the picked up picture for a right eye  78   a  and the picked up picture for a left eye  78   b  from the picture data in the picture file  97 , both of the files  97  and  98  being shown in FIG. 18, in addition to the synthesized picture data file  102 .  
     [0119] Although different data management methods have been described by reference to FIG. 17 to FIG. 19 in the above, in the controlling unit  3 , picture data may be stored in the HDD  51  in conformity with any one of the methods shown in FIG. 17 to FIG. 19. Moreover, any one of the methods shown in FIG. 17 to FIG. 19 may be selected so as to store picture data in the HDD  51 . For example, the saving method shown in FIG. 17 is convenient to the suspension of an editing operation and the reediting, and the saving method shown in FIG. 18 is convenient in a case where a picture is sent to another party in a state of being attached to an electronic mail and the party performs the magnification or the reduction of the attached picture because the methods enables the easy magnification and reduction of the picture. Moreover, the saving method shown in FIG. 19 is convenient to preserve a home page or other Internet data.  
     [0120] By the way, a browsing software for reading out the data that is edited with the aforesaid editing program and is preserved in the form shown in FIG. 17 to FIG. 19 in the recording means such as the HDD  51  and for displaying pictures on the basis of the read out data on the display  55  will be described.  
     [0121] First, the activation of the browsing software is described by reference to FIG. 20. At step S 21 , when, for example, an icon for activating the browsing software displayed on the display  55  is clicked with the mouse  57   b , the MPU  59  reads out the program of the browsing software to the RAM  52  from the HDD  51 , and advances to step S 22 .  
     [0122] At the step S 22 , the MPU  59  makes the display  55  display an activation screen  111  shown in FIG. 21 at about the center of the screen  82 . At this time, the controlling unit for spectacles  6  detects a signal of the activation screen  111  and controls of the turning on and off of the shutter section for a right eye  4   a  and the shutter section for a left eye  4   b  of the shutter spectacles  4 . The details of the operation of the controlling unit for spectacles  6  will be described later.  
     [0123] At the step S 24 , the MPU  59  makes the display  55  display the screen of a browsing software  112  on the screen  82  of the display  55 . That is, the VRAM  56  outputs the picture data of a picture for a right eye on the screen of the browsing software  112  to the display  55  from the memory section  56   a , and outputs the picture data of a picture for a left eye on the screen of the browsing software  112  to the display  55  from the memory section  56   b . The picture for a right eye and the picture for a left eye are alternately displayed on the screen of the browsing software  112  on the display  55  so as to have a parallax to each other. An user wearing the shutter spectacles  4  can thereby look at the screen of the browsing software  112  stereoscopically.  
     [0124] At step S 25 , the MPU  59  opens the folders including the picture data to be edited, i.e. the folders  91 ,  96 , and  101  shown in FIG. 17 to FIG. 19, on the basis of a command from the input unit  57  composed of the keyboard  57   a  and the mouse  57   b . Here, because the selected files  91 ,  96  and  101  are compressed in the JPEG format, the MPU  59  expands the files  91 ,  96  and  101  by the compressing/expanding section  58 , and then reads out the data in the files  91 ,  96  and  101  to the RAM  52 . Then, the MPU  59  makes the display  55  display the picked up picture for a right eye  78   a  and the picked up picture for a left eye  78   b  on the screen of the browsing software  112  displayed on the display  55  so as to have a parallax to each other. That is, when a picked up picture for a right eye formed by the thinning out of even lines from a picked up picture for a right eye of one frame and a picked up picture for a left eye formed by the thinning out of odd lines from a picked up picture for a left eye of one frame, the picture data of both the thinned out pictures being stored in the information files  94  and  98 , are displayed on the display  55 , the VRAM  56  outputs the picture data of the picked up picture for a right eye  78   a  from the memory section  56   a  at first, and then outputs the picture data of the picked up picture  78   b  for a left eye  78   b  from the memory section  56   b  on the basis of the line information indicating which of the pictures the first line of a picture to be displayed is included in. By the repetition of the outputting of the VRAM  56  after that, the stereoscopic picture  78  is displayed on the display  55 . Consequently, the picked up picture for a right eye  78   a  and the picked up picture for a left eye  78   b  are further stereoscopically displayed in a frame body  113  displayed stereoscopically when they are seen by an user wearing the shutter spectacles  4 . The screen of the browsing software  112  makes a stereoscopic picture easy for an user to look at by displaying further stereoscopic picture  78  in the stereoscopic frame body  113  in such a way.  
     [0125] Moreover, the termination operation of the browsing software  112  will be described by reference to FIG. 23. At step S 31 , when the termination indication section  114  located at a corner position and indicated by an “x” is clicked by the mouse  57   b , the MPU  59  begins the termination operation of the browsing software  112 . Then, at step S 32 , the MPU  59  makes the display  55  display a termination screen  115  that is substantially the same as the activation screen  111  at about the center of the screen  82  of the display  55  as shown in FIG. 21. At this time, the controlling unit for spectacles  6  detects the signal of the termination screen  115 , and turns off both of the shutter section for a right eye  4   a  and the shutter section for a left eye  4   b  of the shutter spectacles  4 . The details of the operation of the controlling unit for spectacles  6  will be described later. Then, at step S 33 , the MPU  59  completes the termination operation of the browsing software  112 .  
     [0126] By the way, when the browsing software  112  is activated, it is necessary to drive the shutter spectacles  4 . Accordingly, the step S 22  shown in FIG. 20 is provided. That is, the controlling unit for spectacles  6  is set to detect whether the browsing software  112  is activated or not when the activation screen  111  is displayed on the screen  82  of the display  55 . That is, when the browsing software  112  is activated, as shown in FIG. 24A, the VRAM  56  is set to supply a picture signal in the pattern of, for example, white ? black ? white ? black, for displaying the activation screen  111  to the display  55 .  
     [0127] Now, the detecting section  61  of the controlling unit for spectacles  6  shown in FIG. 7 detects the picture signal in the patter of white ? black ? white ? black, and switches the switch  64  so as to turn off the shutter section for a right eye  4   a  of the shutter spectacles  4  and so as to turn on the shutter section for a left eye  4   b  thereof in accordance with the picture data of a picture for a right eye on the screen of the browsing software  112  output from the memory section  56   a  at first at the step S 25  in FIG. 20 so that an user can look at the picture for a right eye with the user&#39;s right eye. When the picture for a right eye is displayed on the display  55 , the shutter section for a right eye  4   a  takes the open state and the shutter section for a left eye  4   b  takes the closing state consequently.  
     [0128] Next, as shown in the aforesaid FIG. 8, when the detecting section  61  detects the vertical synchronizing signal of the data of a picture for a right eye, the detecting section  61  switches the switch  64  so as to turn off the shutter section for left eye  4   b  of the shutter spectacles  4  and so as to turn on the shutter section for a right eye  4   a  so that the user can look at the picture for a left eye to be displayed on the screen of the browsing software  112  next with the user&#39;s left eye. When the picture for a left eye is displayed on the display  55 , the shutter section for a left eye  4   b  takes the open state and the shutter section for a right eye  4   a  takes the closing state consequently. Hereafter, by such switching of the shutters of the shutter section for a right eye  4   a  and the shutter section for a left eye  4   b  of the shutter spectacles  4  is performed synchronously with the switching timing of the picture for a right eye  78   a  and the picture for a left eye  78   b , the user can stereoscopically look at the picture on the screen of the browsing software  112  displayed on the display  55 .  
     [0129] Incidentally, the MPU  59  may control the display  55  to display an icon, a character and other objects in the region on the screen  82  where the screen of the browsing software  112  is not displayed with a parallax when the MPU  59  detects a picture signal in the pattern of white ? black ? white ? black so that the user can look at all the objects displayed on the screen  82  stereoscopically. Consequently, the whole screen  82  becomes a stereoscopically displayed picture, and it is possible to prevent that the region where the stereoscopic picture  78  composed of the picked up picture for a right eye  78   a  and the picked up picture for a left eye  78   b  is not displayed is displayed flickeringly. The picture signal in the pattern of white ? black ? white ? black is used as a synchronizing signal for synchronizing the shutter spectacles  4  and the pictures displayed on the display  55 , and also is used as a detection signal for detecting the opening of the browsing software  112 .  
     [0130] Moreover, it is necessary to stop the driving of the shutter spectacles  4  when the browsing software  112  is terminated, and accordingly the step S 32  shown in FIG. 23 is provided. That is, the controlling unit for spectacles  6  is set to detect whether the browsing software  112  has been terminated or not when the termination screen is displayed on the screen  82  of the display  55 . That is, when the browsing software  112  is terminated, as shown in FIG. 24B, the VRAM  56  is set to supply a picture signal in the pattern of, for example, white ? black ? black ? white for displaying the termination screen  115  to the display  55 .  
     [0131] Here, when the detecting section  61  of the controlling unit for spectacles  6  shown in FIG. 7 detects the picture signal in the pattern of white ? black ? black ? white, turns off both of the shutter section for a right eye  4   a  and the shutter section for a left eye  4   b  of the shutter spectacles  4  so that both of the shutter section  4   a  for a right eye and the shutter section for a left eye  4   b  take the open state because the stereoscopic picture becomes impossible to look at hereafter. That is, by the turning off of the shutter spectacles  4  to make the shutter sections  4   a  and  4   b  take the open state, two-dimensional display is made to be easy to look at when an user does not make the browsing software  112  be activated.  
     [0132] Incidentally, in the aforesaid case where an icon, a character and other objects in the region on the screen  82  where the screen of the browsing software  112  is not displayed are made to be displayed as a picture with a parallax to enable an user to look at the whole screen  82  stereoscopically, the MPU  59  makes the display  55  stop displaying the icon, the character and other objects as a picture with the parallax, and makes the display  55  display the objects having no parallax when the MPU  59  detects the picture signal in the pattern of white ? black ? black ? white. That is, the picture signal in the pattern of the white ? black ? black ? white is used as a detection signal to turn off the shutter spectacles  4 , and is also used as a detection signal to detect the termination of the browsing software  112 .  
     [0133] As described above, on the screen of the browsing software  112 , when the browsing software  112  is activated, the picture signal in the patter of white ? black ? white ? black is output from the VRAM  56  and the picture signal is detected by the controlling unit for spectacles  6 , and thereby the switching control of the liquid crystal shutters of the shutter section for a right eye  4   a  and the shutter section for a left eye  4   b  of the shutter spectacles  4  can be performed synchronously with the picture data of a picture for a right eye and the picture data of a picture for a left eye, both being alternately output to the display  55  and being displayed on the screen of the browsing software  112 . Consequently, it is possible to remove a defect that, for example, when a picture for a right eye is displayed on the display  55 , the shutter section for a right eye  4   a  takes the closing state and the shutter section for a left eye  4   b  takes the open state and consequently the picture for a right eye is looked at only with the left eye. Moreover, on the screen of the browsing software  112 , when the browsing software  112  is terminated, the picture signal in the pattern of white ? black ? black ? white is output from the VRAM  56  and the output picture signal is detected by the controlling unit for spectacles  6 , and then both of the shutter section for a right eye  4   a  and the shutter section for a left eye  4   b  of the shutter spectacles  4  are turned off to make both of the shutter section for a right eye  4   a  and the shutter section for a left eye  4   b  take the open state, and consequently a two-dimensional display can be made to be easy to look at. Moreover, it is possible to prevent from being noticeable to the user by the use of the above-mentioned picture signal for the activation screen  111  and the termination screen  115 . Incidentally, the picture signals at the time of the activation and the termination of the browsing software  112  are not limited to the patterns of white ? black ? white ? black at the activation and white ? black ? black ? white at the termination, any color and combination may be adoptable provided that they are not conspicuous.  
     [0134] By the way, there is a case where a second stereoscopic picture is displayed on the display  55  in a way of being superimposed on the screen of the browsing software  112  displayed stereoscopically as a fist stereoscopic picture. For example, as shown in FIG. 25, it is such cases as a case where a stereoscopic picture having already been picked up is pasted on the screen of the browsing software  112  and a case where a stereoscopic picture  78  displayed on the screen of the browsing software  112  is moved. As shown in FIGS.  9 A- 9 D and FIG. 25, in the case where a picked up picture for a right eye formed by the thinning out of the even lines of the horizontal scan lines of a picked up picture for a right eye of one frame and a picked up picture for a left eye formed by the thinning out of the odd lines of the horizontal scan lines of a picked up picture for a left eye of a frame are alternately displayed, when the stereoscopic picture  78  is pasted or moved on the screen of the browsing software  112 , there happens a case where the horizontal scan lines of a picture for a left eye of the stereoscopic picture  78  are placed on the horizontal scan lines of a picture for a right eye of the screen of the browsing software  112 . That is, a picture for a left eye of the stereoscopic picture  78  is displayed when a picture for a right eye is displayed on the screen of the browsing software  112 , or a picture for a right eye of the stereoscopic picture  78  is displayed when a picture for a left eye is displayed on the screen of the browsing software  112 . In such a case, the user has become impossible to look at the stereoscopic picture  78  stereoscopically. Accordingly, in the case where the horizontal scan lines of the screen of the browsing software  112  and the horizontal scan lines of the stereoscopic picture  78  do not agree with each other when the stereoscopic picture  78  is moved as shown in FIG. 25, the browsing software  112  moves the stereoscopic picture  78  by one horizontal scan line in the vertical direction so that the horizontal scan lines of the screen of the browsing software  112  and the horizontal scan lines of the stereoscopic picture  78  agree with each other.  
     [0135] To put it concretely, as shown in FIG. 26, at step S 41 , for example, the stereoscopic picture  78  located at a first position on the upper left side in FIG. 25 is selected with the mouse  57   b , and a second position on the lower right side in FIG. 25 is designated as the position of the stereoscopic picture  78  to be shifted or to be pasted. Then, at step S 42 , the MPU  59  moves the stereoscopic picture  78  located at the first position to the second position, or pastes the stereoscopic picture  78  at the second position.  
     [0136] Furthermore, at step S 43 , the MPU  59  detects whether the Y-coordinate of the position coordinates A(X, Y) of the stereoscopic picture on the upper most stream in the scanning direction at the second position as the position of the stereoscopic picture  78  to be moved or to be pasted is located on the horizontal scan line of a picture for right eye of the screen of the browsing software  112  or is located on the horizontal scan line of a picture for a left eye of the screen of the browsing software  112 . Then, the MPU  59  terminates the processing thereof when the first horizontal scan line of the stereoscopic picture  78  and the horizontal scan line of the screen of the browsing software  112  agree with each other, and advances its processing to step S 44  when the first horizontal scan line of the stereoscopic picture  78  and the horizontal scan line of the screen of the browsing software  112  do not agree with each other. That is, when the Y-coordinate is located on the horizontal scan line of a picture for a right eye in the screen of the browsing software  112  in the case where the first horizontal scan line of the stereoscopic picture  78  is a horizontal scan line of a picture for a right eye, the MPU  59  terminates the processing thereof on the supposition that the horizontal scan line of the screen of the browsing software  112  and the first horizontal scan line of the stereoscopic picture  78  agree with each other. Moreover, when the Y-coordinate is located on the horizontal scan line of a picture for a left eye in the screen of the browsing software  112  in the case where the first horizontal scan line of the stereoscopic picture  78  is a horizontal scan line of a picture for a right eye, the MPU  59  advances the processing thereof to the step S 44  on the supposition that the horizontal scan line of the screen of the browsing software  112  and the first horizontal scan line of the stereoscopic picture  78  do not agree with each other.  
     [0137] At the step S 44 , the MPU  59  moves the stereoscopic picture  78  by one horizontal scan line upwardly or downwardly. Thereby, the MPU  59  make the first horizontal scan line of the stereoscopic picture  78  and the horizontal scan line of a picture on the screen of the browsing software  112  agree with each other, and enables an user to look at the stereoscopic picture  78  stereoscopically. Then, the MPU  59  terminates the processing thereof.  
     [0138] As described above, because on the screen of the browsing software  112 , when the stereoscopic picture  78  is moved or pasted, the horizontal scan lines of a picture on the screen, which is a frame of the stereoscopic picture  78 , of the browsing software  112  and the horizontal scan lines of the stereoscopic picture  78  always agree with each other, an user can always look at the stereoscopic picture.  
     [0139] Moreover, as shown in FIG. 27, there is a case where the stereoscopic picture  78  as a second stereoscopic picture displayed on the screen of the browsing software  112  as a first stereoscopic picture is expanded or reduced. As shown in FIGS. 9A to  9 D and FIG. 27, in the case where a picked up picture for a right eye formed by the thinning out of even horizontal scan lines of a picked up picture for a right eye of one frame and a picked up picture for a left eye formed by the thinning out of the odd horizontal scan lines of a picked up picture for left eye of one frame are alternately displayed, when the stereoscopic picture  78  is expanded or reduced on the screen of the browsing software  112 , there is a case where the horizontal scan lines of a picture for a left eye of the stereoscopic picture  78  are situated on the horizontal scan lines of a picture for a right eye on the screen of the browsing software  112 . That is, the picture for a left eye of the stereoscopic picture  78  is displayed when the picture for a right eye is displayed on the screen of the browsing software  112 , or the picture for a right eye of the stereoscopic picture  78  is displayed when the picture for a left eye is displayed on the screen of the browsing software  112 . In this case, an user becomes impossible to look at the stereoscopic picture  78  stereoscopically. Accordingly, in the case where the horizontal scan lines of the screen of the browsing software  112  and the horizontal scan lines of the stereoscopic picture  78  do not agree with each other when the stereoscopic picture  78  is expanded or reduced as shown in FIG. 27, the browsing software  112  moves the stereoscopic picture  78  by one horizontal scan line in the vertical direction so that the horizontal scan lines of the screen of the browsing software  112  and the horizontal scan lines of the stereoscopic picture  78  agree with each other.  
     [0140] To put it concretely, as shown in FIG. 28, at step S 51 , a stereoscopic picture  78  is selected with the input unit  57 , and the display magnification of the selected stereoscopic picture  78  is designated. Then, at step S 52 , the MPU  59  makes the display  55  display the stereoscopic picture  78  by expanding or reducing it at the display magnification designated by an user.  
     [0141] Then, at step S 53 , the MPU  59  detects whether the Y 1 -coordinates and Y 2 -coordinates of the position coordinates B 1 (X 1 , Y 1 ) and B 2 (X 2 , Y 2 ) of a picture  121   a  obtained by the expansion of the stereoscopic picture  78  or a picture  121   b  obtained by the reduction of the stereoscopic picture  78  on the upper most stream in the scanning direction is located on the horizontal scan line of a picture for a right eye on the screen of the browsing software  112  or is located on the horizontal scan line of a picture for a left eye on the screen of the browsing software  112 . Then, the MPU  59  terminates the processing thereof when the first horizontal scan line of the picture  121   a  or  121   b  and the horizontal scan line of the screen of the browsing software  112  agree with each other, and advances the processing thereof to step S 54  when the first horizontal scan line of the picture  121   a  or  121   b  and the horizontal scan line of the screen of the browsing software  112  do not agree with each other. That is, when the Y 1 -coordinates and Y 2 coordinates are located on the horizontal scan line of a picture for a right eye on the screen of the browsing software  112  in the case where the first horizontal scan line of the picture  121   a  or  121   b  is a horizontal scan line of a picture for a right eye, the MPU  59  terminates the processing thereof on the supposition that the horizontal scan line of the screen of the browsing software  112  and the first horizontal scan line of the picture  121   a  or  121   b  agree with each other. Moreover, when the Y 1 -coordinate and the Y 2 -coordinate are located on the horizontal scan line of a picture for a left eye on the screen of the browsing software  112  in the case where the first horizontal scan line of the picture  121   a  or  121   b  is a horizontal scan line of a picture for a right eye, the MPU  59  advances the processing thereof to the step S 54  on the supposition that the horizontal scan line of the screen of the browsing software  112  and the first horizontal scan line of the picture  121   a  or  121   b  do not agree with each other.  
     [0142] At the step S 54 , the MPU  59  moves the picture  121   a  or  121   b  by one horizontal scan line upwardly or downwardly. Thereby, the MPU  59  make the first horizontal scan line of the picture  121   a  or  121   b  and the horizontal scan line of a picture on the screen of the browsing software  112  agree with each other. Or, as anther method, the MPU  59  again makes the display  55  display the picture  121   a  or  121   b  by expanding or reducing at the magnification nearest to the display magnification designated by an user so that the first horizontal scan line of the picture  121   a  or  121   b  and the horizontal scan line of the picture on the screen of the browsing software  121  agree with each other. By means of the method described above, the MPU  59  makes the first horizontal scan line of the picture  121   a  or  121   b  and the horizontal scan line of the picture on the screen of the browsing software  112  agree with each other, and enables the user to look at the expanded or reduced picture  121   a  or  121   b  stereoscopically. Then, the MPU  59  terminates the processing thereof.  
     [0143] As described above, because on the screen of the browsing software  112 , when the picture  121   a  or  121   b  is expanded or reduced, the horizontal scan lines of a picture on the screen, which is a frame of the picture  121   a  or  121   b , of the browsing software  112  and the horizontal scan lines of the stereoscopic picture  78  always agree with each other, and thereby the user can always look at the stereoscopic picture.  
     [0144] By the way, the editing program for editing the picture composed of such a picture for a right eye  41   a  and a picture for a left eye  41   b  and the browsing software for looking at the picture edited with the editing program may be memorized to be preserved in a magnetic disk, a magneto-optical disk, an optical disk, a semiconductor memory and other recording media in addition that the editing program and the browsing software are memorized to be preserved in the HDD  51 . In this case, when the recording media are loaded on the driving section  131  as shown in FIG. 6 and an operation for activating the recording media is performed with the input unit  57 , these programs are read out by the MPU  59  from the recording media to the RAM  52  through a bus. Then, the above-mentioned processing is executed by the program read out from the record media.  
     [0145] Moreover, these programs may be installed in the HDD  51  from the driving section  131  through a provision medium for providing the programs to an user such as the magnetic disk, the magneto-optical disc, the optical disk, and the semiconductor memory where the programs are stored. Moreover, in addition to installing these programs in the HDD  51  through such a provision medium, it is also possible to install the programs in the HDD  51  through a transmitting/receiving section  132  by radio or by wire from a download site.  
     [0146] Next, a network system  151  using the thus structured stereoscopic picture system  1  will be described by reference to FIG. 29. The network system  151  is equipped with a server unit  152  for accumulating stereoscopic picture data and a plurality of personal terminal units  153  for downloading stereoscopic picture data by accessing the server unit  152 . Then, the server unit  152  and the plural personal terminal units  153  are connected with each other through the network.  
     [0147] The server unit  152  has a structure that is substantially similar to that of an ordinary computer. The server unit  152  comprises a memory section  161  for storing the stereoscopic picture data and other data and programs, a read-only memory (hereinafter, also referred to as ROM)  162  for storing various programs such as a program for controlling the operation of the whole of the server unit  152 , a RAM  163  for accepting a program stored in the ROM  162  temporarily, a transmitting/receiving section  164  for performing the transmission and the reception of data with the personal terminal units  153 , and a controlling section  165  composed by a MPU for controlling the whole of the server unit  152 .  
     [0148] The program for controlling the operation of the whole of the server unit  152  is read out from the ROM  162  to the RAM  163  temporarily to be executed by the controlling section  165  for controlling the operation of the whole of the server unit  152 . In the server unit  152 , a home page including a stereoscopic picture and other objects is provided in the memory section  161  to enable the personal terminal units  153  to access the home page.  
     [0149] Moreover, the personal terminal units  153  correspond to the aforesaid controlling unit  3  and have a structure similar to that of the controlling unit  3 . That is, as shown in FIG. 29, each of the personal terminal units  153  comprises a HDD  51  for storing perusing and searching software (browsing software  112 ) for displaying a picture  41  stereoscopically, an electronic mail program and other programs, a RAM  52  for accepting temporarily an application program and other programs and data stored in the HDD  51 , a display  55  for displaying the picture  41  and other pictures, a VRAM  56 , an input unit  57 , a compressing/expanding section  58  for expanding data in the JPEG format and for compressing data in the JPEG format, and a MPU  59  for controlling the whole of the personal terminal unit  153 .  
     [0150] Each of the personal terminal units  153  is installed in, for example, a personal user&#39;s house, and is connected with a provider in the Internet  154  through a modulator-demodulator and a telephone line, a terminal adapter and the Integrated Services Digital Network (ISDN) line, a cable television (CATV) line, and other communication lines. For example, when an user peruses a home page provided in the server unit  152 , the user operates the input unit  57  to perform the inputting operation of the uniform resource locator (URL) of a desired home page, and then the browsing software  112 , the transmission control protocol/internet protocol (TCP/IP) and other programs are performed. As a result, the personal terminal unit  153  accesses the server unit  152  through the Internet  154  to download the contents of the accessed home page for displaying the contents on the display  55 . Moreover, the user can transmit an electronic mail to the personal terminal unit  153  of another user through the Internet  154  by the use of the personal terminal unit  153  of the user on the transmission side.  
     [0151] Moreover, a pair of shutter spectacles  4  for looking at a picture displayed on the display  55  stereoscopically is connected with each of the personal units  153  between the VRAM  56  and the display  55  through the controlling unit for spectacles  6  as shown in FIG. 29. Consequently, the user can stereoscopically look at the picture that is displayed in the home page and has a parallax by wearing the shutter spectacles  4 . A case where an user peruses a home page provided in the server unit  152  with a personal terminal unit  153  in the above-mentioned network system  151  will be explained. Data for a stereoscopic picture is stored in the server unit  152  as a picture having a parallax in, for example, a way shown in FIG. 19. As the data for the stereoscopic picture, as shown in FIG. 19, there is accumulated in the server unit  152  the synthesized picture data file  102  in which the synthesized picture data formed by the synthesis of the picture data of a picked up picture for a right eye formed by the thinning out of even lines from a picked up picture for a right eye of one frame and the picture data of a picked up picture for a left eye formed by the thinning out of odd lines from a picked up picture for a left eye of one frame. Because the data size of such a synthesized picture data file  102  is small, the time for downloading the synthesized picture data file  102  from the server unit  152  can be shortened.  
     [0152] On the other hand, in the case where a home page is perused by a personal terminal unit  153  as shown in FIGS. 20 and 21, at first, at step S 61  shown in FIG. 30, an icon for activating the browsing software that is displayed on the display  55  is clicked with the mouse  57   b , and then the MPU  59  reads out the program of the browsing software from the HDD  51  to the RAM  52  for displaying the activation screen  111  shown in FIG. 21 on the screen  82  of the display  55 . Here, as shown in FIG. 24A, the VRAM  56  supplies a picture signal in the pattern of white ? black ? white ? black for displaying the activation screen  111  to the display  55 . The detecting section  61  of the controlling unit for spectacles  6  detects the picture signal in the pattern of white ? black ? white ? black, and detects that the browsing software  112  has been activated. When the activation of the browsing software  112  has been completed, the picture data of a picture for a right eye and the picture data of a picture for a left eye, both of the pictures being displayed on the screen of the browsing software  112 , are alternately output from the VRAM  56 , and then the picture for a right eye and the picture for a left eye are alternately displayed on the display  55  so as to have a parallax.  
     [0153] At the same time when the activation of the browsing software  112  has been completed, at step S 62 , the controlling unit for spectacles  6  controls the shutter spectacles  4  so that the shutter section for a right eye  4   a  of the shutter spectacles  4  takes the open state and the shutter section for a left eye  4   b  takes the closing state when the picture for a right eye is displayed on the screen of the browsing software  112 , and then so that the shutter section for left eye  4   b  of the shutter spectacles  4  takes the open state and the shutter section for a right eye  4   a  takes the closing state when the picture for a left eye is displayed on the screen of the browsing software  112 , and further so that the switching operations are repeated. By the execution of the switching of the shutters of the shutter section for a right eye  4   a  and the shutter section for a left eye  4   b  of the shutter spectacles  4  synchronously with the timing of the switching of the picture for a right eye and the picture for a left eye displayed on the screen of the browsing software  112 , an user can stereoscopically look at a picture displayed on the display  55  by the browsing software  112 .  
     [0154] Then, at step S 63 , when an user performs the input operation of the URL of a desired home page by operating the input unit  57 , the personal terminal unit  153  accesses to the server unit  152  through the Internet  154 , and downloads the contents of the accessed home page to display the contents on the display  55 . Moreover, a stereoscopic picture provided in the home page may also be selected to be downloaded. The picture data of the selected stereoscopic picture is accumulated in the memory section  161  of the server unit  152  in the way shown in FIG. 17. The picture data shown in FIG. 17 is composed of the data file of picked up pictures for a right eye  92 , the data file of picked up pictures for a left eye  93  and the information file  94  which consists of the information relating to the files  92  and  93 . Because there are the data file of picked up pictures for a right eye  92  and the data file of picked up pictures for a left eye  93  in the picture date, it is possible to perform the editing operations of expanding or reducing the picture for a right eye and the picture for a left eye in conformity with the editing program in the personal terminal unit  153 .  
     [0155] In the aforesaid network system  151 , the picture data for a stereoscopic picture is accumulated in the server unit  152  in the way shown in FIG. 17 or FIG. 19, and an user wearing the shutter spectacles  4  looks at a home page displayed on the display  55  on the personal terminal unit  153  side, and thereby the user can stereoscopically look at the picture displayed on the display  55 . For example, when the user purchases goods through the Internet  154 , the user can stereoscopically look at the goods and it becomes possible for the user to perform easily the judgment whether the user should purchase the goods or not.  
     [0156] Moreover, in the network system  151 , electronic mails can also be exchanged among the personal terminal units  153 . For example, there is a case where the picture data photographed with the aforesaid digital camera  2  with the attached adapter  5  and processed by the aforesaid edit processing is attached to an electronic mail to be transmitted to another personal terminal unit  153 . Now, a case where picture data is preserved in the HDD  51  of a personal terminal unit  153  on the transmission side in the way shown in FIG. 17 will be explained. In this case, as described above, there are stored in the folder  91  the data file of picked up pictures for a right eye  92 , the data file of picked up pictures for a left eye  93  and the information file  94  which consists of the information relating to the files  92  and  93 .  
     [0157] At the personal terminal unit  153  on the transmission side, an user operates the input unit  57  to transmit the folder  91  to the address of the server equipment  152  which is the transmission place. The transmitted folder  91  is thereby accumulated in the memory section  161  of the server unit  152 . After that, when the personal terminal unit  153  of an user who is an addressee accesses the address of the server unit  152 , the personal terminal unit  153  of the addressee downloads the folder  91  to accumulate it in the HDD  51 .  
     [0158] In the personal terminal unit  153  on the side of the addressee, when the addressee looks at the picture preserved in the folder  91 , the browsing software  112  is activated by the processing shown in FIG. 20. Then, the user as the addressee opens the received file  91 , and the data file of picked up pictures for a right eye  92  and the data file of picked up pictures for a left eye  93  are read out from the VRAM  56  to be displayed on the display  55  alternately in a way that the picked up picture for a right eye and the picked up picture for a left eye have a parallax on the display  55 . Thereby, the user can look at the picture displayed on the screen of the browsing software  112  stereoscopically in a state that the user wears the shutter spectacles  4 . By the way, because there are the data file of picked up pictures for a right eye  92  and the data file of picked up pictures for a left eye  93  in the folder  91 , the user can perform the re-editing of the picked up picture for a right eye  78   a  and the picked up picture for a left eye  78   b  such as the enlarging or the reducing of them.  
     [0159] Next, a case where picture data are preserved in the HDD  51  in the way shown in FIG. 18 will be described. In this case, as described above, there are preserved in the folder  96  the picture data file  97  including the picture data of the picture  41  composed of the picture for a right eye  41   a  and the picture for a left eye  41   b  as shown in FIG. 5 and the information file  98  composed of the information for generating the picked up picture for a right eye  78   a  and the picked up picture for a left eye  78   b  from the picture data file  97 .  
     [0160] The personal terminal unit  153  on the transmission side transmits the folder  96  to the personal terminal unit  153  of the user who is the addressee through the server unit  152  by the operation of the input device  57  by the user on the transmission side.  
     [0161] In the personal terminal unit  153  on the side of the addressee, when the addressee looks at the picture preserved in the folder  96 , the browsing software  112  is activated by the processing shown in FIG. 20. Then, the user as the addressee opens the received file  97 , and the data file of picked up pictures for a right eye  92  and the data file of picked up pictures for a left eye  93  are read out from the VRAM  56  to be displayed on the display  55  alternately in a way that the picked up picture for a right eye and the picked up picture for a left eye have a parallax on the display  55 . Thereby, the user can look at the picture displayed on the screen of the browsing software  112  stereoscopically in a state that the user wears the shutter spectacles  4 . Now, because there is the picture data file  97  in the folder  96 , the user can perform the re-editing of the picture for a right eye and the picture for a left eye such as the enlarging or the reducing of them as shown in FIG. 10.  
     [0162] Because each personal terminal unit  153  has at least the browsing software  112  in the aforesaid network system  151 , the picture data of a stereoscopic picture can be exchanged by the attachment of the stereoscopic picture to an electronic mail.  
     [0163] Although examples in which picture data are compressed in the JPEG format to be preserved or processed by other processing are described in the above, the compressing system of the present invention may be the motion picture expert group (MPEG) and other systems. Moreover, although examples concerning static images are described in the above, dynamic images are also adoptable. Although the invention has been described in its preferred form with a certain degree of particularity, obviously many changes and variations are possible therein. It is therefore to be understood that the present invention may be practiced than as specifically described herein without departing from scope and the sprit thereof.
