## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an image obtaining method, an image pick-up device and an image pick-up information transmitting system, and more particularly to an image obtaining method, an image pick-up device and an image pick-up information transmitting system capable of obtaining under a remote control an image from other communication devices connected by a communication.
Further, the present invention relates to an image transmitter and a print system, and more particularly to an image transmitter and a print system for editing the image inputted by the image transmitter and transmitting an edited print image to a printer.
2. Description of Related Art
An image pick-up system, an electronic camera and a computer system for controlling the electronic camera and a control method for them in which the control parameters of the electronic camera such as an exposure, various kinds of balance controls, etc. can be set by a host computer side connected thereto by a communication path are disclosed in Japanese Patent Application Laid-Open No. 5-219422.
On the other hand, the electronic camera in which an image picked up by the electronic camera is directly transmitted to a printer by a wireless communication to instruct the image to be printed has been hitherto known.
Further, Japanese Patent Application Laid-Open No. 9-261619 discloses a monitor system of a construction site in which the state of a construction work site is shot by a television camera, and its static image is transmitted by the wireless communication network of a portable telephone and a receiving part displays the received static image by a monitor television, records the image by an image recording video recorder and the recorded image is printed out by a printer.
The image pick-up system, the electronic camera and the computer system for controlling the electronic camera and the control method for them disclosed in the Japanese Patent Application Laid-Open No. 5-219422 are adapted to remotely control the electronic camera from the computer connected to the electronic camera, and therefore, the parameters upon picking up an image can be set and an image picking-up operation can be performed by the electronic camera and the picked-up image can be obtained from the electronic camera. However, in order to set various kinds of parameters of the electronic camera and obtain the picked-up image from the electronic camera, it has been necessary to previously provide a dedicated command for the computer.
In the case where the computer to which the electronic camera is connected is an apparatus employed only for controlling the electronic camera, it does not cause any trouble. However, for instance, in the case where the electronic camera is connected to a personal computer, a PDA (personal digital assistant), a portable telephone, etc., these devices to which the electronic camera is connected need to previously have dedicated commands for controlling the electronic camera. Since the control method for the electronic camera is not ordinarily a generalized using method of each device to which the electronic camera is connected, it has been a utilization method unfamiliar to a user and the user has needed to forcedly make a troublesome setting such as the installation of a device driver only for controlling the electronic camera. Especially, in the case each device to which the electronic camera is connected is a small communication device such as a portable telephone or the like, it has been disadvantageously difficult to meet the device in view of the configuration of a hardware due to a condition under which resources for storing the device driver or performing an information processing are limited.
Further, since in the control mode of a computer connected to the conventional electronic camera, an image pick-up mode is completely separated from the transfer mode of an image, a computer side cannot inconveniently instruct an image to be freely picked up.
Still further, in the case where the computer side instructs an image to be obtained, there has been hitherto only a function for obtaining the picked up image which is recorded in the electronic camera, so that the computer side cannot instruct a continuous operation for picking up an image and obtaining the picked up image. Therefore, an operation has been undesirably complicated.
On the other hand, in the case where the conventional electronic camera instructs the recorded image to be transmitted to a printer by a wireless communication and to be printed, the electronic camera only can inconveniently instruct one sheet of the image to be directly printed. Therefore, when a plurality of sheets of the same images are printed, it has been necessary to transmit the required number of sheets of images. Further, when a trimming operation is performed on the image, the image data of an area which is not actually printed has been also transmitted to the printer and the trimming processing has been applied to the area of the image data from the printer side. Therefore, a useless transmitting time has been required.
Furthermore, the monitor system disclosed in the Japanese Patent Application Laid-Open No. 9-261619 also cannot transmit the edited print image from the television camera of a transmitting side or the portable telephone side.

The recording medium 54 is detachable recording means represented by semiconductors such as memory cards and MOs, magnetic recording and optical recording.
The wireless communicating device of the electronic camera 10 employed when the image data is transmitted to and received from other device comprises a transmitting and receiving device 60 for encoding and decoding the image data or the information data of the directories or the like and transmitting or receiving the data on a carrier wave in accordance with a command from the information processing device 44, the antenna 62 for transmitting and receiving the carrier wave and the data and a communication connector 64 for connecting together the mutual devices for transmitting and receiving the information such as the image data through a cable to perform a communication by a wired communication. Through the communicating device configured as described above, the data stored in the image files, the RAM, the ROM and the frame memory 48 can be transmitted to other communication devices or the information can be received from other communication devices to store in each storing device.
Further, when the information is transmitted to and received from other communication device through the connector 64, the mutual devices for transmitting and receiving the information are connected together through the cable to convert the information into an electric signal or an optical signal and perform a wired communication.
Further, the electronic camera 10 is provided with a D/A converter 66 for displaying the image data on the display 16, a character generator 68 for converting code information commanded from the information processing device 44 into the data of characters or messages to be displayed and a calendar clock 70 for ticking dates or time.
Furthermore, when a command to inquire the directory structure and the file information of the image data in relation to the image pick-up conditions or the transfer of the image data is received from other communication device (such as the image information receiver) by communication, the information processing device 44 transmits the information of the directories in which the names of files classified for each of the parameters indicating the image pick-up conditions or the parameters indicating the properties of the image to the image information receiver. The information of the directories constituting classification information is composed of information including a virtual directory (including a virtual folder) and a virtual image file or the name of a path of a virtual image file or the like. The information may be previously stored in the ROM (a storing device) or may be generated on the basis of the image pick-up conditions provided in the electronic camera 10 or the properties of the image which can be converted.
With reference to FIG. 4, the contents of a display shown in the display 16 when the mode of the electronic camera 10 is set to the setup mode are shown.
In the same figure, when the setup mode 38 is set, a display is made to change date and time, change the image pick-up or shooting mode, change the number of pixels of a recorded image. Set an auto-off time, and adjust the volume of an alarm sound. These settings can be changed by operating the input device 50 provided for the electronic camera 10.
Further, the display of a date and time represents the date and time which the calendar clock 70 is currently ticking, and when a user performs a selection for changing numeric values to change the numeric values, the information of the inputted date and time is transferred to the calendar clock 70 from the information processing device 44 to start ticking the inputted date and time.
For the image pick-up or shooting mode displayed on the display 16, are represented various image pick-up or shooting modes of “FINE”, “NORMAL”, “ECONOMY” whose image data compressibilities are different from one another. In the case of an example in FIG. 4, the “FINE” mode is a setting largest in its quantity of image data and low in its compressibility.
As for the number of pixels of the recorded image, the number of pixels (resolution) of VGA (640×480) and XGA (1024×768) is shown. Accordingly, when a high image quality print is performed, a recording is carried out in advance under the conditions of the large number of pixels and a low compressibility. Further, when the image data is applied to a use for transferring it to other communication device, the quantity of image data is set in accordance with the use when the use is predetermined by performing a recording operation with the small number of pixels and high compressibility and so on.
Further, an auto-off time represents a setting of timeout time, after the lapse of a prescribed time, for automatically entering the power conservation mode (for example, modes for lowering the processing speed of the information processing device 44 and stopping the supply of power to peripheral elements which are not used). When the electronic camera 10 is activated under a state in which the electronic camera 10 enters the power conservation mode, the user operates any of the input device 50 or transmits a command for urging the electronic camera to be activated from other communication device through a communication. A power conservation mode setting device for setting or canceling the power conservation mode may performed by the information processing device 44, or an independent power conservation mode setting device may be provided for an exclusive use.
For setting an alarm sound, the volume of beep sound is set when an alarm is given to the user at the time of activating the electronic camera 10, at the time of completion of a communication process, during an image pick-up or an image shooting operation. These information such as date and time, the image pick-up or shooting mode and the number of pixels of the recorded image are displayed together with the image during reproduction thereof as shown in the display 16 in FIG. 1.
Now, an image pick-up process or a shooting process performed by the electronic camera 10 configured as described above will be described below.
The image of an object to be shot is formed on the photo-receiving face of the image pick-up or shooting device 42. The image of the object to be shot thus formed undergoes a photo-electronic conversion and the converted image is outputted to the image processing device 46. The obtained image data is subjected to an amplification or noise reduction process in the image processing device 46 and the resultant data is stored in the frame memory 48 on a temporary basis. The information processing device 44 transfers the image data stored in the frame memory 48 to the D/A converter 66 one after another to display the image data on the display 16.
When an instruction to pick up or shoot an image is received by pressing the release button 20 provided in the input device 50 or through a communication, a mode for picking up or shooting the image of the object to be shot is started. Then, the information processing device 44 performs an image pick-up or shooting process under a prescribed exposure condition, a flash light emitting condition, a zoom condition and a focus condition as instructed. The image of the object to be shot which is formed on the photoreceiving face of the image pick-up device 42 is subjected to a photo-electronic conversion and the converted image is outputted to the image processing device 46, the image undergoes the amplification or noise reduction process and the resultant image is temporarily stored in the frame memory 48. The information processing device 44 instructs the image data stored in the frame memory 48 to be converted on the basis of a prescribed number of pixels, a compressibility, a sampling method and color information. Then, the information processing device 44 instructs the recording medium interface 56 to sequentially perform a process to record the image data on the recording medium 54 or perform a process to transmit the image data to other devices through the transmitting and receiving device 60.
When the picked up image is manually transmitted to other devices, the mode switching dial 22 is set to the communication mode 32 to press a transmitting button provided on the input device 50. Then, the information processing device 44 performs processes for sequentially reading out the designated image data from the recording medium 54 or the frame memory 48, converting the image data into a prescribed data format and then transmitting the converted image data to an external part through the transmitting and receiving device 60, the antenna 62 or the communication connector 64.
FIG. 5 is an external appearance view of a communication device.
As shown in the same figure, a communication device 80 (the image information receiver) comprises an antenna 82 for performing a wireless communication with a public circuit, a wireless communicating device 84 for performing a wireless communication with other peripheral communication devices such as the electronic camera, a display 88 composed of a color liquid crystal display or the like for displaying the thumbnail image 86 of communication information or a selected image file, designating devices 90, 90 . . . for designating and selecting the file names of telephone numbers, characters, images and sounds and designating devices or addresses to which the data of the file names are outputted, a speaker 92 serving as a telephone receiver and outputting a sound, a microphone 94 for inputting sounds and a communication connector 96 for performing a wired communication with other peripheral communication devices at an image pick-up position.

Further, referring to FIG. 5, on the display 88, are displayed a battery remaining capacity display 122 indicating the remaining capacity of the battery which is a power source of the communication device 80, a received radio intensity display 124 for displaying the intensity of wireless received radio, a run mode display 126 for informing a user of a current display mode (Folder Browse mode) and pointers 130, 130 for scrolling and displaying the names of directories 128, 128 . . . displayed on the basis of the information of the directories transmitted from the image pick-up device, the names of files 129, . . . 129 and the names of directories 128 . . . or the names of files 129 which are present in the upper part and the lower part but are not displayed.
When the user designates the run mode or the names of the directories and the names of the files, the user moves a designating frame to perform a setting by using a cursor key or the like provided on the designating device 90. As shown in FIG. 5, in the Folder Browse mode, is displayed “CAM¥ROOT” that shows the root directory of the electronic camera 10 in which a currently displayed directory name 128 (a display character string represented by D:+a directory name like D: 001 Vacation) and a file name 129 (a display character string represented by F:+a file name like F:Shoot.jpg) are stored.
For instance, when the file name 129 of “F:Shoot.jpg” is selected from this display, the communication device 80 sends a command for requesting the electronic camera 10 to transmit the file of “Shoot.jpg”. Then, the electronic camera 10 performs an image pick-up operation to transmit the obtained image data by picking up or shooting an image to the communication device 80, so that the communication device 80 can obtains the requested image data.
In this case, if a designation for transmitting the obtained image data to other communication device can be simultaneously performed, a convenient system will be realized. For this purpose, a pull model in which the communication device 80 can get the image from the electronic camera 10 is applicable thereto.
The display program of the Folder Browse mode is not an exclusive program for acquiring the image files from the electronic camera 10 but an ordinary generalized file display program (filer program). Therefore, a personal computer or a digital audio player as well as the electronic camera 10 connected to the communication device through the communicating device can also obtain and transmit the files.
FIG. 6 is a block diagram of a communication processing system of the communication device.
With reference to FIG. 6, the transmitting and receiving part of the communication device 80 comprises a public circuit wireless communicating device 98 for performing a wireless communication to transmit and receive audio information or image data through a public circuit, a public circuit transmitting and receiving device 100, a wireless communicating device 84 for performing a wireless communication with other communication devices, a communication connector 96 for connecting a cable when a wired communication is performed, a transmitting and receiving device 102 and a transmitting and receiving buffer 104 for storing data transmitted and received in real time on a temporary basis.
Further, the communication device 80 is provided with a CPU106 for controlling the entire part of the device, a PROM108 in which a program for operating the CPU106, various kinds of constants, telephone numbers, addresses of communication partners, etc. are written, a RAM 110 as storing means which forms a work area when the CPU106 performs processings, and a calendar clock 112 ticking dates and time.
The CPU106 in the communication device 80 and a peripheral circuit including the display 88 and the designating device 90 are connected together by a communicating device such as a bus line or an I/O, etc. and the CPU106 can control each peripheral circuit.
The communicating device of the wireless communicating device 84 and the electronic camera 10 is communicating means using the light of radio waves, ultrasonic waves, infrared rays or the like for the carrier wave. In the case where the radio wave is employed, specifications of “Bluetooth” and wireless LANs (Local Area Networks) to which an attention has been recently paid may be used. In the case where the infrared ray is employed, an interface device based on the specification of IrDA may be used.
Further, a communicating device when a communication is performed by using a wired communicating device may use a serial communicating device such as RS-232, RS-422, USB. etc., or an interface device using a parallel signal may be employed.
FIG. 7 shows configurations of connection of a variety of communication devices in the case where information is transmitted and received by using an image pick-up information transmitting system.
As shown in this figure, the image pick-up information transmitting system 118, 118A comprises the electronic camera 10, 10A and the communication device 80, 80A. The user operates the communication device 80, 80A to select and designate image picked up or shot or stored by the electronic camera 10, 10A and reads out the images. The user further transmits the images to a desired server 120 or other communication devices not shown through the network of the public circuit. The server 120 may perform a service to print the images on sheets of paper based on the transmitted image information and deliver them to the user.
Further, a communication network such as the public circuit and a short-range communication network to communicate with the communication device located in the vicinity of the communication device 80 are simultaneously activated, so that while the communication device 80 receives the image data from the electronic camera 10, it can transmit the image data which is being received to the server 120.
A recording directory structure of the image file in the recording medium 54 of the electronic camera 10 is shown in FIG. 8.
In this figure, the directory structure of the file of the image picked up or shot comprises a root “ROOT”, each directory group 140 showing a section “001 Vacation” indicating an image picked up or shot during the holidays of a user and “002 Birthday” and each image file group 142 of “Dscf0001.jpg”, “Dscf0002.jpg” . . . The above described directory names are generally represented by “nnnXXX . . . X”, numeric characters indicating the directory numbers of 001 to 999 are applied to nnn and arbitrary alphabetical names are applied to XXX . . . X. Further, the file name is generally represented by “Dscfmmmm.jpg”. Dscf designates an identifier for indicating the file of the image picked up or shot by the electronic camera. mmmm designates file numbers from 0001 to 9999. jpg designates an identifier for indicating the image data recorded by a compressing method of JPEG system.
The path of the image file can be expressed by numeric characters of seven digits of nnn-mmmmm by using the above described directory numbers and the file numbers (refer to the display “001-0001” of the display 16 shown in FIG. 1).
FIG. 9 shows an internal structure of the image file.
In this figure, the image file comprises a tag 144 in which information attached to the image such as the image pick-up or shooting conditions is described, a Thumbnail 146 as image data for a heading and a main image 148. In a tag 144, are attached and described shooting dates, whether or not a flash is used, the state of an exposure mode (set on the basis of an aperture priority in an example shown in FIG. 9), a set white balance (set on the basis of daylight in an example shown in FIG. 9), titles, focus information, image pick- up or shooting position information obtained when GPS devices are connected. When the values of these information are not unknown, it is also possible to describe “UNKNOWN”.
The Thumbnail 146 has image data of the main image 148 whose number of pixels (the number of pixels of VGA or XGA) is reduced to about 160×120 as a heading attached thereto and stored therein. In the main image 148, each of the number of pixels with VGA, XGA or the like designated and the information of the image data compressed with a prescribed compressibility are recorded. The Thumbnail 146 is not limited to the form shown in FIG. 9 and a plurality of image information whose number of pixels are different mutually may be recorded.
FIG. 10 shows the paths of virtual directories in which the names of picked-up or shot image files and the names of virtual files to be picked-up are classified for each of pick-up or shooting conditions by using a tree structure.
When the electronic camera receives a command to inquire the directory structure of the image files with respect to a transfer of the image, the information processing device 44 transmits the information of the directories composed of the virtual directories (including virtual folders) classified as shown in FIG. 10 and the virtual image file names to the communication device 80.
Referring to FIG. 10, in the lower hierarchy of the directory “Root”, directories “001 Vacation” and “002 Birthday” in which the files names of picked up or shot images are stored are provided. Further, as the virtual file names for obtaining the data of shot image or the virtual directory names in which the virtual file names are registered, file names or directory names mentioned below are registered. “Shoot.jpg” is a basic function file name for picking up or shooting an image. When this virtual file name is selected by the user, the communication device 80 transmits a request for transmitting a file to get this file to the electronic camera 10. When the electronic camera 10 receives the transmission request, the electronic camera 10 sets all the shooting or image pick-up parameters such as the exposure mode or the flash to pick up to an automatic mode to pick up or shoot the image. The image obtained by shooting the image is transmitted to the communication device 80. At this time, the image data obtained by picking up or shooting the image may be transmitted to the communication device 80 and recorded on the recording medium 54 in the electronic camera 10. Further, in the case where the image is picked up again under the same conditions as those under which the image is picked up at the last time, the image file got by photo-shooting the image at the last time may be discarded and a new image got by newly shooting an image may be overwritten thereon, or the file name of the image file obtained as a result of previously shooting the image may be changed and the changed file name may be stored. In this case, the setting modes or the image pick-up or shooting conditions upon shooting the images are stored in the tag 144 of the image file.
“LastShot.jpg” is also a basic function file name. When this file name is selected by the user, the electronic camera 10 transmits the image data picked up at the last time and recorded on the recording medium 54 to the communication device 80. The image data obtained by shooting the image at the last time may be image data got or shot by manually operating the release button 20 of the electronic camera 10 or image data got as a result of instruction to shoot an image through a communication.
A directory of “StorobeAuto” indicates a selection of a mode for picking up or shooting an image by automatically controlling the light emission of a flash. When the virtual file names stored in this virtual directory are selected, an image is picked up or shot by setting the light emission of the flash to an automatic mode and the image data obtained by shooting the image is transmitted to the communication device 80.
In such a way, hierarchies are provided for the function directories, so that a plurality of image pick-up or shooting parameters can be classified and set.
A directory of “StrobeOn” indicates a selection of a mode for picking up or shooting an image by forcedly emitting the light of a flash. When the virtual file names stored in this virtual directory are selected, the light emission of the flash is set to a forced light emission mode to pick up the image and the image data obtained by picking up or shooting the image is transmitted to the communication device 80.
A directory of “StrobeOff” indicates a selection of a mode for picking up or shooting an image without emitting the flash light in order to shoot the image of a night scene or the like. When the virtual file names stored in this directory are selected, an image is picked up or shot without emitting the flash light and the image data obtained by shooting the image is transmitted to the communication device 80.
A directory of “AutoExposure” indicates a selection of a mode for automatically picking up or shooting an image by controlling an exposure such as an aperture, shutter speed, etc. on the basis of a prescribed program. When the virtual file names stored in this virtual directory, an image is picked up or shot under an automatic exposure control and the image data obtained as a result of shooting the image is transmitted to the communication device 80.
A directory of “Shutter Priority” indicates a selection of a mode for picking up or shooting an image under an automatic exposure control on a shutter speed priority basis. When the virtual file names stored in this directory are selected, the image is picked up or shot under an automatic exposure control on a shutter speed priority basis and the image data got by shooting the image is transmitted to the communication device 80.
A directory of “Aperture Priority” indicates a selection of a mode for picking up or shooting an image under an automatic exposure control on a diaphragm aperture priority basis. When the virtual file names stored in the virtual directory are selected, the image is picked up or shot under the automatic exposure control on the diaphragm aperture priority basis and the image data obtained by shooting the image is transmitted to the communication device 80.
A virtual file name of “AutoExposure.jpg” registered in the lower hierarchy of the directory “StorobeAuto” designates a selection of a mode for picking up or shooting an image by performing an automatic exposure control such as a diaphragm aperture, shutter speed, etc. on the basis of a prescribed program. When the virtual file names stored in this virtual directory are selected, the image is shot or picked up under the automatic exposure control and the image data obtained by shooting the image is transmitted to the communication device 80.
In a similar way, a shutter file name of “Shutter Priority.jpg” registered in the hierarchy below the virtual directory of “Strobe Auto” designates a selection of a mode for picking up or shooting an image under an automatic exposure control on a shutter speed basis. A virtual file name of “AperturePriority.jpg” designates a selection of a mode for picking up or shooting an image under an automatic exposure control on a diaphragm aperture priority basis.
Although the virtual file name of “AutoExposure.jpg” is registered in the hierarchy below the virtual directory of “StrobeOn” shown in FIG. 10, the virtual file names of “ShutterPriority.jpg” and “AperturePriority.jpg” are not registered. In such a way, when the forced light emission of a flash is instructed, the image pick-up or shooting mode which is ordinarily unnecessary may not be registered.
FIG. 11 shows the paths of the virtual directory names and the virtual filenames classified into the parameters indicating the image pick-up conditions and the parameters indicating the properties of the image in a tree structure representation.
As shown in this figure, a virtual directory of “Shoot” is registered and virtual directories such as “QVGA”, “VGA” and “SVGA” are further registered for each of the parameters indicating the properties concerning the number of pixels of the image. In the virtual directories concerning the number of pixels, virtual files of “Economy.jpg”, “Normal.jpg” and “Fine.jpg”, etc. indicating compressive conditions are further registered. Still further, the above described virtual directory groups and the virtual file groups may be registered in the virtual directory of “Strobe Auto”.
The user selects the file name indicating the desired image pick-up conditions and the properties of the image so that the user can easily obtain the desired picked up or shot image.
The virtual directory of “QVGA” designates a virtual directory in which a series of virtual images of 1⁄4 VGA size are stored. The virtual directory of “VGA” designates a virtual directory in which a series of image files of VGA size are stored. The virtual directory of “SVGA” designates a virtual directory in which a series of image files of SVGA size are stored. The number of pixels is not limited to the above described “QVGA”, “VGA” and “SVGA” and the different number of pixels such as “QQVGA”, “XGA” or the like may be used. Besides, it is to be understood that the classification of the compressibility of the image is not limited to the above described examples.
In Table 1 shown below, the function directory names and the virtual file names, and examples in which the image pick-up or shooting conditions set by the image pick-up device correspond to the converting functions of the image data obtained by shooting the image are exemplified.

Now, description examples of the directory information to be transmitted to the image information receiver from the image pick-up device are shown in FIG. 12.
As shown in FIG. 12, in the directory information, are described a symbol “¥” indicating that a current directory (current folder) is a root directory and a folder list in which the directory names or the file names registered in the current directory are registered.
Further, a line in which a section flag of “/D” is described indicates the display of the name of a directory. A line in which a section flag “/F” is described indicates the display of a file name. A section flag of “/S” indicates the size information of a file. Since “LastShot.jpg” designates the file name of the already picked up image, an actual file size “/S=195 KB” is shown. However, “Shoot.jpg” designates a virtual file name of an image which is not picked up or shot. Accordingly. “/S=200 KB” indicates an expected file size calculated by the information processing device on the basis of the parameters showing the image pick-up conditions or the properties of the image. Further, attributes of “exclusively used for reading” indicating that the file name is designated exclusively for reading or attribute information of “not displayed” indicating the file name which is not displayed for the user may be added thereto.
The image information receiver calculates a communication time required for obtaining the file on the basis of the expected file size information and may display the expected communication time. Further, when the size of the image file to be obtained is too large so that it exceeds the receiving capacity of the image information receiver, or when it is expected that a communication needs more time than a prescribed time, an alarm may be sent to the user or the reception of the image may be stopped.
In the case where the image information receiver receives the directory information shown in FIG. 12 and informs the user of the information, for example, the display of the directory information shown in the display 88 in FIG. is performed. In the case where “D: 001 Vacation” is selected while the directory information is displayed on the display 88 in FIG. 5, the display of the display 88 shifts to a Folder Browse display shown in FIG. 13.
The display shown in FIG. 13 represents the list of the file names 129, 129 . . . of the picked up or shot images which are registered in the directory “001 Vacation”.
In this figure, when a desired image file name is selected, the image of the selected file name is transmitted from the image pick-up device so that the image information receiver can get the desired image. A display part of “D: . . . ” shown in FIG. 13 is selected when the display is instructed to shift to a display of a master directory (or folder) located in an upper hierarchy. For displaying the directory information, the file names may be displayed as shown in FIGS. 5 and 13, or the tree structure may be displayed as shown in FIGS. 10 and 11.
FIG. 14 shows a processing procedure of a communication actually performed between the image pick-up device and the image information receiver.
A communication method shown in FIG. 14 shows a pull model of a type that the user can operate the communication device 80 (for instance, a portable telephone high in its frequency of carrying or usage) to readily get an image recorded in the electronic camera 10.
As shown in FIG. 14, in step S100 of “set an operation mode to a communication mode” (described it only as S100 in abbreviation, hereinafter), the operation mode of the electronic camera 10 is set to a communication mode and the operation mode of the communication mode 80 is set to an image obtaining menu in S102 of “set an operation mode to an image obtaining menu”. Then, the communication device 80 transmits a command to the electronic camera 10 in S104 of “a request for connection” in order to start a communication. The electronic camera 10 receives the command of “request for connection” and sends a response for performing a subsequent connection of communication to the communication device 80 in S106 of “completion of connection”. In the case where the mode of the electronic camera 10 is a power conservation mode, when the electronic camera receives the “request for connection”, the electronic camera 10 automatically cancels or releases the power conservation mode to perform a subsequent communication process.
When the connection of a communication is completed, the communication device 80 transmits a command for obtaining folder list information to the electronic camera 10 in accordance with S108 of “a request for folder list”.
When the electronic camera 10 receives the command of “request for folder list”, a process for transmitting and receiving information related to the directories (folders) is performed in accordance with S110 of “folder list information”. Here, the information processing device 44 transmits the information of the file name or the directory names classified for each of the parameters indicating the pick up conditions or the properties of the image stored in the storing device. Further, when the electronic camera first receives the request for folder list, a current directory may be set to the root directory of the recording medium 54 or may be previously set to a directory high in its usage rate.
The communication device 80 displays (browsing) the folder list information on the basis of the folder list information received in accordance with S112 of “display folder list”. In the folder list information to be displayed, the folder list may be displayed by characters or displayed in the tree representation as shown in FIGS. 10 and 11.
Then, the user performs a browsing process from the displayed folder list, and then decides whether or not the target file of the image to be obtained exist in accordance with S114 of “a target file exists in a current directory?”.
If the target file to be obtained is not present in the current directory, the pointer 130, 130 shown in FIG. 5 will be selected or a different directory will be selected to select an image under the desired image pick-up conditions (S116 of “select a folder at a moving end”). Then, the processing program of the communication device 80 transmits a current folder change request to the electronic camera 10 in S118 of “request to change (SetPath) a current folder”. The electronic camera 10 changes the current folder (current directory) on the basis of the folder change request. When the change of the current folder is completed, the electronic camera 10 informs the communication device 80 of the completion of the change of the current folder in accordance with S120 of “complete the change of a current folder”.
When the communication device 80 receives the notification of completion of the change of the current folder, the execution program of the communication device 80 branches before S108 to transmit again a request for a desired folder list to the electronic camera 10. Then, a next folder list is displayed.
If the target file to be obtained exists, the execution program will branch to S122 of “select a target file”. Then, the file name of the desired image pick-up conditions is selected and set by using a cross key or a setting button provided on the designating device 90. After that, the electronic camera 10 is requested to transmit the image of the selected and designated file name in accordance with S124 of “request to transmit a file (GET)”.
The electronic camera 10 decides whether or not a file demanded in accordance with S126 of “a demanded file is a function file?” is a function file. If the demanded file is the function file, the procedure advances to S128 of “set the image pick-up parameters on the basis of the function folder of the demanded file and the contents of the function file” to set the image pick-up parameters on the basis of the designated folder name and the file name and set the image pick-up conditions.
In S130 of “perform an image pick-up or shooting operation”, an image pick-up or shooting operation is performed in accordance with the image pick-up conditions set on the basis of the image pick-up or shooting parameters set as described above. When the image pick-up process is completed, the image data is converted into the properties of the image instructed as required and the image data is transmitted to the communication device 80 in accordance with S132 of “transmit file data”.
Further, in the S126, when the demanded file is not the function file (when the demanded file is a file of a picked up image or the like), the image data recorded in the recording medium 54 is read out in accordance with next S134 of “read out the target file from the recording medium”, the image data is converted into the properties of the image according to an instruction as required and the image file is transmitted to the communication device 80 in accordance with the S132 of “transmit file data”.
When the image information receiver receives the image file, a process is performed for storing the received data in a memory or transferring the data to other devices through a public circuit in accordance with S134 of “store received data in a memory or transmit to a public circuit”.
In S136 of “there exist other files to be obtained?”, the user is asked to obtain other files. If there is a request for getting other files, the S136 branches to the S112. If other files are not obtained, the communication device 80 will transmit a disconnection request command for finishing a communication to the electronic camera 10 in accordance with S138 of “request for disconnection”. Then, in S140 of “end”, the process for obtaining the image is finished.
When the electronic camera 10 receives the disconnection request command, the process for transmitting the image is finished in accordance with S142 of “end”.
As described above, the folder list information (directory information) classified in accordance with the image pick-up conditions is transmitted to the communication device 80 and displayed on the display 88 of the communication device 80, so that the user can rapidly select desired kinds of image pick-up or shooting conditions meeting a use and can acquire the picked up image. Further, since the communication device 80 side does not need to previously have setting information related to the parameters indicating a variety of image pick-up conditions of the image or the properties of the image, the burden of the processing programs of the communication device 80 side can be advantageously reduced.
Still further, since the image pick-up device transmits the directory (folder) information classified for each of the parameters indicating the image pick-up conditions or the properties of the image to the communication device 80 to select and designate a desired image, the communication device 80 side is provided with only a program for reading an ordinarily widely utilized file to select and designate a plurality of kinds of images. Further, the processing program of the communication device 80 also merely utilize a tool high in its frequency of usage and familiar to the user, a comfortable operability can be obtained with small burden.
Furthermore, the electronic camera may be set to a power conservation mode and the conservation mode may be cancelled when the electronic camera receives the “request for connection” from the communication device 80 to start communication and information processing processes. Such a configuration allows the image pick-up device to activate a communication mode only at the time of necessity from its stand-by mode, a power consumption to be suppressed and the life of a battery to be lengthened.
In the above described embodiment, although the image pick-up device according to the present invention is described as the electronic camera with the image pick-up device, it is to be understood that the present invention is not limited to the electronic camera and a scanner provided with the image pick-up device may be employed.
Further, in the above described embodiment, although the communication device 80 is described in an example for performing a wireless communication with other communication devices via the public circuit by using the wireless communicating device, it is to be noted that the present invention is not limited to the wireless communication and the wired communicating device may be employed and the communicating device for communicating with wired communication networks may be employed.
Still further, in the above described embodiment, although the image file converted by the information processing device 44 is described as the image file obtained by changing the compressibility of the image data relative to the original image file and the image file whose number of pixels is changed, the present invention is not limited thereto and an image file whose color tone such as gradation, chrome, etc. is changed, an image file whose white balance is changed, an image file whose sharpness is changed, an image file obtained by carrying out a sampling conversion such as YCC 420, YCC422 or the like for converting the image data into a luminance signal and a color difference signal, an image file obtained by performing an RGB conversion for converting the image data into the primary colors of red, green and blue, an image file obtained by performing a white/black conversion, an image file obtained by performing a sepia color conversion and files of different image recording forms, etc. may be newly registered.
Still further, in the case where the display 88 of the communication device 80 is a display capable of performing a color display, the virtual file of a color image may be automatically designated. In the case where the display 88 is only provided with a function of a white/black display, the virtual file of a white/black image may be automatically designated so as to reduce the burden of the user in view of operation.
Still further, the above mentioned communication device (image information receiver or the like) may be a portable terminal equipment or a simple communication device such as a remote controller as a representative example.
Furthermore, in the above described explanation, although the communication device obtains the image from the image pick-up device as an example, it is to be understood that the present invention is not limited thereto and the communication device (information receiver) may select a file name showing desired functions on the basis of the directory information presented from the electronic device to request the electronic device to perform an operation corresponding to the function file name so that the electronic device can perform the function allocated to the function file name and transmit a response to the information receiver. This response may be a response of a command type or a file in which a description showing the result of the operation of the electronic device is present.

Further, the electronic camera 210 is provided with a display 238 for displaying the inputted image data, the print information and the print conditions received from a printer through the communicating device, a D/A converter 240 for converting the data to be displayed on the display 238, an attribute register 242 in which the attributes of a communication partner are stored and a power supply part 244 for supplying a power to respective elements provided in the electric camera 210.
In the information processing device 220, are provided a ROM in which operation programs or respective constants are stored and a RAM as storing means which forms a work area when the programs are executed, which are not shown in FIG. 15.
A control unit of a printer 250 shown in FIG. 15 comprises a CPU (information processing device) 252 for governing the general processes of the printer 250 and editing the displayed image and the print information, a detachable HDD (hard disk drive) 254 for recording a run program or data such as the image data, etc., the display 258 for displaying the print information or a print image, an input device 260 for inputting the print information or processes to the printer 250 by a user, a communicating device 262 having an oscillating part for transmitting and receiving the data to/from the electronic camera 210 and other external devices, a plurality of transmitting and receiving parts 263,263 composed of a transmitting part for transmitting the data on the carrier wave, a receiving part for performing a process to separate the data on the received carrier wave and a switching circuit for switching the transmission and reception of the data, antennas 264, 264 for transmitting and receiving the carrier wave and the data, a general purpose interface 268 for transmitting and receiving the image data to/from a printer unit or a scanner, etc. by a communication, and a ROM. RAM 270 as storing means in which the programs of the CPU 252 or constants such as the print conditions or the like are stored and which serves as the work area of the CPU 252.
The printer unit (print device) of the printer 250 comprises an interface 272 for communicating with the control unit to receive the image data, a RAM 274 as storing means which serves as the work area of the information processor of the printer unit and a print engine 280 for feeding print sheets of paper from a sheet feed part 276 and delivering the print sheets of paper to an output tray 278 after a printing operation.
Now, the image shooting process of the electronic camera 210 configured as described above will be described below.
An image to be shot or picked up is formed on the light receiving face of the CCD (solid state image pick-up element) 214 through the lens group 216. Then image of the object to be shot undergoes a photo-electronic conversion to become an electric charge signal of a quantity corresponding to the quantity of incident light of each sensor in the CCD. The electric charge signal accumulated in the CCD 214 is sequentially outputted in accordance with a shooting timing signal and converted into the digital image data of R, G and B by the A/D converter 218.
The image data obtained in such a way is subjected to processes of amplification and noise reduction in the image processing device 222 and the processed image data is stored in the memory buffer 224 on a temporary basis. The information processing device 220 successively transmits the image data stored in the memory buffer 224 to the D/A converter 240 and displays on the display 258.
When the user presses the recording button provided on the input device 226, the electronic camera 210 enters a mode for shooting or picking up the image of the object to be shot. Then, the information processing device 220 performs a process for sequentially recording the image data on the recording medium 228 relative to the recording medium I/F 230. When the user pushes the transmitting button provided on the input device 226, the information processing device 220 sequentially reads out the designated image data from the recording medium 228, converts the image data into a designated format (including formats after a compression process or a communication error correction function process is performed) and then performs a process for transmitting the converted image data to the external devices such as a personal computer or a printer, etc. through the communicating device 232 and the antenna 236.
Further, when the user edits the image, the cursor key provided on the input device 226 is operated to select the image to be printed, and the function switch is set to a function of “print and edit” to edit the image. At this time, the communicating device 232 starts a connection process of communication with the printer 250 in order to decide whether or not the printer 250 is connected to the communicating device 232.
If the printer 250 is already prepared, the communicating device 232 and the printer 250 will start a communication therebetween, the information related to the print conditions including the resolution of the printer 250 and the size or kinds of sheets of paper with which the printer is charged will be received and stored in the RAM of the information processing device 220 and displayed on the display 238 to inform the user of the information. The user efficiently sets and inputs the print conditions or the print information by referring to the display 238. Then, a new print image is generated on the basis of the set information. When the user does not edit the image to be printed, the user decides the image size using an input image obtained by shooting or picking up an image in such a manner as described below.
Then, the image processing device 220 decides whether or not the image size of the input image obtained by shooting the image or the edited image is larger than an image size required for printing by the printer. When it is decided that the image size is larger than the image size required at the time of printing, the image processing device 222 automatically resizes the input image or the edited image so that the image size thereof is changed to an image size required for printing, generates a new print image and transmits the new print image to the printer.
On the contrary, when it is decided that the image size of the input image or the edited image is not larger than an image size necessary at the time of printing, the input image or the edited image is directly transmitted as the print image to the printer.
Further, when the printer is not prepared yet so that the communicating device 232 cannot communicate with the printer 250, default print conditions stored in the ROM of the information processing device 220 may be displayed on the display 238 so that the user can edit the image.
Referring to FIG. 16, an editing process flow will be described below.
FIG. 16 shows print order information when a shot or picked up input image 282 is subjected to a trimming process to generate an output image 284.
According to FIG. 16, the input image 282 is displayed on the display 238 of the electronic camera 210. The user first designates the print range of the input image 282. In order to designate the print range, the cursor key or the determining switch provided in the input device 226 is operated to designate, for example, the coordinate values(X1, Y1) of a start point from an origin (X0, Y0) of the input image 282 and the size XL and YL of the output image or the coordinate values (X2, Y2) of an end point. Further, in place of the process for designating the coordinate values and the size of the output image 284, the aspect ratio of the image to be printed and the central position and the size or the enlargement ratio of the output image 284 may be set.
Further, as shown in FIG. 16, the size of the image to be printed which is displayed on the basis of the print information received from the printer 250 can be selected and set to 45×35 mm, kinds of sheets (seal paper, ordinary paper, glossy paper, postcard, etc.) can be selected and set, and the print conditions (monochrome, color, sepia, an adjustment of chroma, an adjustment of density, etc), the resolution of an image (dot/mm) and the number of sheets of paper (the number of print sheets, the quantity of print and layout information on one print sheet etc.) can be set.
Even when the image information finer and having a gradation higher than the capacity and resolution of the printer is transmitted to the printer, this only needs a useless communication time and is wasteful, because the image is printed by lowering the resolution and the gradation in the printer. Therefore, the image obtained by automatically resizing is transmitted to the printer.
In the case where the image data of the shot image has the resolution of 2000×1000 and the gradation of 10 bits and the resolution of the printer is 1800×1000 and the printer has the gradation of 10 bits, the electronic camera 210 performs an editing process for converting the image into the print image data having the resolution of 1800×1000 and the gradation of 10 bits and transmits the print image data to the printer.
When the setting of the print conditions is completed as described above, the information processing device 20 performs the editing process for trimming the image and converting the resolution on the basis of the set print conditions to generate the print image.
The print image obtained in such a way and the print information such as the print sheet, the number of print sheets, etc. are transmitted to the printer 250 by pushing the transmitting button provided in the input device 226. As described above, since the image data located in the print range and the print information only required as less as possible are transmitted to the printer 250, a transmitting time can be reduced and a rapid and efficient printing process can be achieved.
In the printer 250, the inputted image data or the set print information are displayed on the display 258 through the communicating device 262 and the printing process is performed on the basis of the designated print information. Then, the number of sheets of the output image 284 for which the printing process is designated can be obtained. Further, in accordance with the instruction of the user, the image data recorded in the HDD 254 can be synthesized, displayed and printed. In this case, a display equal to that shown in FIG. 16 is represented on the display 258 of the printer 250. The print information can be edited in accordance with the print resolution of the printer 250, the print sheets with which the printer is charged and the print characteristics.
