Abstract:
[Problem] To provide an educational toy which allows an observed action to be experienced artificially. [Solution] A toy system ( 900 ) is used by bringing a magnifying-glass type hand-held instrument ( 930 ) into contact with a page ( 912 ) of a main body portion ( 910 ) having a picture portion ( 914 ). The magnifying-glass type hand-held instrument ( 930 ) captures an image of the picture portion ( 914 ), and determines the location, within the image in said picture portion, that has been captured. From pre-stored image data of a picture image that is the same as the picture portion ( 914 ), image data for a part (a partial image) corresponding to the location being captured are then read out and are displayed on a touch panel ( 942 ). If the location being captured fulfills certain location conditions, one image element from image elements W 41  to W 49  is also selected as a special image and is displayed superimposed on the partial image.

CROSS REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application is a National Stage Application, filed under 35 U.S.C. § 371, of International Application No. PCT/JP2014/083231, filed Dec. 16, 2014, which claims priority to Japanese Application No. 2014-017907, filed Jan. 31, 2014; the contents of which are hereby incorporated by reference in their entirety. 
     
    
     BACKGROUND 
       [0002]    1. Technical Field 
         [0003]    This invention is related to the information presentation system. 
         [0004]    2. Description of Related Art 
         [0005]    There are proposed technologies that present information using codes that are invisible to humans. 
         [0006]    For example, Japanese Unexamined Patent Application Publication No. 2003-242168 (“JP2003-242168”) describes the technology that presents information using a head-mounted display. The head-mounted display described in said literature has a half-mirror in the optical path for the user to see the external scene, and it has a photo-receiver device (image sensor) that can photograph the external scene reflected by the half-mirror. When the user wears this head-mounted display and sees the displayed object (embedded with invisible codes), the image photographed with the image sensor corresponding to the invisible code is read from the server system and the image is projected on the half-mirror by the image-display device installed in the head-mounted display. 
       BRIEF SUMMARY 
       [0007]    According to JP2003-242168, the user wearing the head-mounted display can see the image, which does not originally exist, overlaid on the displayed object. Separately from significance of information presentation, the experience of seeing on the screen the objects that normally cannot be seen with the naked eye in the real world is very impressive to anyone. It is not difficult to imagine how deeply children would be impressed. It seems that it is worthwhile to utilize this effect in the intellectual training of children. 
         [0008]    The purpose of this invention is to provide the information presentation system and associated program with enhanced attractiveness. 
         [0009]    The information presentation system of this invention is equipped with a portable electronic device (such as the handy loupe-type device  930  in  FIG. 1 ) that consists of an information section (such as the picture section  914  in  FIG. 1 ) listing information, an imaging section (such as the camera module  955  in  FIG. 2 ), a display section (such as the touch panel  942  in  FIG. 2 ), a memory section (such as the semiconductor memory incorporated in the IC memory  952  and 
         [0010]    SoC  951  in  FIG. 2 ) and a control section (such as the control board  950  and SoC  951  in  FIG. 2 ). When the imaging section recognizes the information section, the image is drawn in the information section in such a way that the photographed position in the information section can be identified on the basis of the recognized image. The memory section stores the image data (such as the picture-image data  522  in  FIG. 10 ) for the display of the partial image from the information section in the display section. By identifying the photographed position in the information section based on the image recognized by the imaging section, the control section controls the display of the partial image in the information section corresponding to the photographed position in the display section, doing so on the basis of the image data (such as step S 10  in  FIG. 12 ). 
         [0011]    Furthermore, in the information presentation system of this invention it is preferable that when the position condition for the display of the special image designated by the photographed position is satisfied, the control section will display the special image (such as the no.  1  image element W 41  of the special image in  FIG. 5 ) atop the partial image being displayed by the display section (such as steps S 30  through S 34  in  FIG. 12 ). 
         [0012]    Furthermore, in the information presentation system of this invention it is preferable that the portable electronic device be equipped with a clocking section (such as the clock section  953  in  FIG. 2 ), and that the control section variably controls the special image based on clocking information provided by the clocking section (such as step S 32  in  FIG. 12 ). Furthermore, in the information presentation system of this invention it is preferable that the control section stores the history of the special images displayed in the display section (such as the special-image display history data  560  in  FIG. 9 ) and that the control section has the record-display control section with which to display the past displayed special images in the display section (such as the record-display control section  222  in  FIG. 8  and steps S 50  through S 56  in  FIG. 12 ). 
         [0013]    Furthermore, in the information presentation system of this invention it is preferable that the information section configures the close-up photographed image with a plurality of different images corresponding to the photographed position. 
         [0014]    Furthermore, in the information presentation system of this invention it is preferable that the information section be configured with images in which the code image (such as the code image  20  in  FIG. 3 ), being invisible to the naked eye, is embedded with the designated layout rules. 
         [0015]    Furthermore, in the information presentation system of this invention it is preferable that the portable electronic device has the loupe-shaped peep window and that the display section is installed at the peep window. 
         [0016]    Furthermore, this invention is related to the information presentation program (such as the handy device-control program  502  in  FIG. 9 ) that lets a computer, being equipped with the imaging section and the display section, function as a photographed-position identification means that identifies the photographed position in the information based on the image recognized by the imaging section when the imaging section recognizes the information listed in the information section (such as the control section  200  and the photographed-position identification section  206  in  FIG. 8  and in step S 8  of  FIG. 12 ), and, as a partial-image display control means that controls the display in the display section, the partial images in the information section that are stored in the computer based on the photographed position identified by the photographed-position identification means (such as the control section  200  and the partial-image display control section  208  in  FIG. 8 , and step S 10  of  FIG. 12 ). 
         [0017]    Furthermore, in the information presentation program of this invention it is preferable that the computer functions as a photographed-position condition identification means that identifies the position condition of the photographed position and as a special-image display control means that controls the display of the special image on the partial-image displayed in the display section when the position conditions satisfies the position condition to display the designated special image. 
         [0018]    Furthermore, in the information presentation program of this invention it is preferable that the computer has the clocking section and that the computer functions as a clocking-information-based image-selection means that controls variable display of the special images based on the clocking information from the clocking section. 
         [0019]    Furthermore, in the information presentation program of this invention it is preferable that the computer functions as a special-image display history memory means that stores the history of the special images displayed in the display section into the memory section and as a record-display control means that controls the display of past displayed special images in the display section based on the history. 
         [0020]    Furthermore, in the information program system of this invention it is preferable that the photographed-position identification means identifies the photographed position by matching the pattern of the images in the picture images. 
         [0021]    Furthermore, in the information program system of this invention it is preferable that the photographed-position identification means identifies the photographed position by using the code image (which is invisible to the naked eye) in the picture images.

     DETAILED DESCRIPTION 
       [0034]    Hereinafter, embodiments for carrying out this invention will be described. However, it should be noted that embodiments of this invention are not limited to examples given below. 
         [0035]      FIG. 1  is a view that illustrates the configuration of a toy system  900  for children. The toy system  900  of the embodiment of this invention has the main body section  910  and the handy loupe-type device  930 . 
         [0036]    The main body section  910  is a book consisting of a plurality of pages  912  equipped with the picture section  914 . In this embodiment of this invention, it is the so-called “ring file” in which a plurality of removable pages  912  is bound by the ring  918  in the binder frame  916 . However, this can be a notebook or a book type that is hard-bound by glue or cord. 
         [0037]    The number of pages  912  can be suitably set, and a page  912  can be a folding type. In the example, the configuration shows one picture section  914  on one page  912 . However, a plurality of picture sections  914  can be configured on one page  912 , or one picture section  914  can be configured across a plurality of pages  912 , the so-called “spread book” configuration. The picture section  914  can be printed on each page  912 , or it can be pasted on each page  912  as a seal sheet. 
         [0038]    The handy loupe-type device  930  is an electronic device equivalent to a computer having the external appearance of a loupe. The user holds the device like a loupe and peers into the picture section  914 . 
         [0039]      FIG. 2  is a view that illustrates the configuration of the handy loupe-type device  930  of the embodiment of this invention.  FIG. 2  (1) is a frontal view facing the user, and  FIG. 2  (2) is a side view. 
         [0040]    The external appearance of the handy loupe-type device is the shape of a loupe. More specifically, the rod-shaped handle  936  is extended from the side of the disk-type housing section  932  through the medium of the operation section  934 . At the back of the disk-type housing section  932 , the semi-cylindrical-shaped lighting-skirt section  938  made of transparent resin or semi-transparent resin is provided. It is preferable that the length of the handle  936  be set in such a way that when the lighting-skirt section  938  is placed on the picture section  914 , it can stand by itself without falling. 
         [0041]    At the center of the front side of the disk-type housing section  932 , the peep window  940  is installed and the touch panel  942  is embedded. 
         [0042]    The control board  950  is built into the disk-type housing section  932 . Mounted on the control board  950  are, for example, SoC (System-on-Chip)  951 , IC memory  952 , the clock section  953 , the touch-panel driver IC 954  for operating the touch panel  942 , and the camera module  955 . 
         [0043]    These function through means of electrical power from the built-in battery  937  stored in the handle  936 . 
         [0044]    The CPU built in the SoC  951  integrally controls the operation of the handy loupe-type device  930  by reading the program and data stored in the IC memory  952  and by computing. 
         [0045]    The program and various data are stored in the IC memory  952 . Included among various data is the image data of the picture image of the picture section  914  printed on each page  912 . 
         [0046]    The clock section  953  is a real-time clock IC built in a typical PC, and as always it clocks the current time and date and outputs to SoC  951 . Of course, it is acceptable to implement the clock section  953  as a software clock in which SoC  951  computes the time and date based on the clock signal. It is preferable to have a clocking section that clocks at least one of time, date or season. 
         [0047]    The camera module  955  is a well-known image sensor that contains the optical elements such as lenses, filters, and the sensor chip that generates the photographed image data and outputs to SoC  951 . The camera module  955  of the embodiment of this invention can photograph the visible-light region as a matter of course but also invisible areas such as infrared region or ultraviolet region. The camera module  955  is installed in such a way that it can photograph objects at the back side of the disk-type housing section  932  and so that its optical axis L runs through the center of the screen of the touch panel  942 . The optical specification, including the focus distance, is set in such a way that the close-up photograph is possible, whereby the camera can be focused on the object pushed against the edge surface of the lighting-skirt section  938 . It is acceptable to provide the auto-focusing function. In this embodiment, the infrared transmission filter is provided at the front of the camera module  955 . The infrared transmission filter in this embodiment is for the camera module  955  to efficiently recognize the infrared ray reflected by the visible printing section. It is not restricted to anything particular as long as the material can absorb the visible light and pass through the infrared ray. 
         [0048]    The operation section  934  comprises a plurality of operation switches  935  for the user to input operations. 
         [0049]      FIG. 3  is a view that illustrates the configuration of the picture section  914  of this embodiment of this invention. 
         [0050]    In this embodiment, the picture section  914  is the image content. The picture images categorized as illustrations are provided as examples, but categories are not limited to these as long as listed information has the information section, such as photographs, typography, etc. It can also be character information (to be included in “image” in this embodiment). It can be a two-dimensional image or stereoscopic image. 
         [0051]    The picture section  914  is comprised of the visible print section that is printed with normal visible ink reflecting the infrared ray and the invisible print section that is printed with the infrared ray absorbing ink invisible to the naked eye of the user. In this embodiment, for example, the invisible print section is printed with the paint with high light absorption rate for the ray in the near infrared region. If only the visible print section is graphically illustrated, it is as shown in  FIG. 3  (1). This is the image visible to the naked eye of the user, that is to say the figure of the picture section  914  in the visible-light region. In addition, if the invisible print section is graphically illustrated schematically, it will be as shown in  FIG. 3  (2). 
         [0052]    The visible print section of the picture images of the picture section  914  contains a single or a plurality of observation objects  30  (two locations in the example illustration, the observation object at right  30   a  and the observation object at left  30   b ). The observation object  30  will be defined by a unique specific range  32  (two locations in the example illustration, the specific rage  32   a  at right and the specific range  32   b  at left) in each data. The specific range  32  in this embodiment is a rectangular region surrounding the observation object  30 , being defined by the coordinates of the four corners in the picture-image coordinate system. 
         [0053]    The invisible print section is comprised of a plurality of code images  20  arranged by the designated layout rules so that the photographed position of the picture image can be identified on the basis of the photographed image when the camera module  955  takes a photograph. In other words, the code images  20  invisible to the naked eye are embedded in the picture image of the picture section  914 . Furthermore, “photographing” in this embodiment includes not only the acts of recording images as photograph or video but also all other acts of image recognition by the camera module  955 . 
         [0054]    Because the code image  20  is printed with the invisible infrared-absorbent ink and the visible print section is printed with the ink reflecting the light in the infrared region, if a photograph is taken by the camera module  955  with the infrared transmission filter, the code image  20  can be recognized and identified as illustrated in  FIG. 3  (2). In this embodiment, it is preferable that the infrared light source for radiating the infrared ray is installed at the picture section  914  and that the identification rate of the code image  20  be further improved. For example, the infrared LED is installed at the back of the disk-type housing section  932 , and the infrared light is radiated toward the object being photographed by the camera module  955 . 
         [0055]    Each code of the code image  20  supports its unique information. A plurality of codes is arranged according to designated rules. More specifically, the code images  20  of proper posture are placed at a designated spacing in the first row from the top. In the second row from the top, the code images  20  of the tilted posture rotated  45 ° counter-clockwise from the proper posture are placed at a designated spacing, i.e., half-spacing offset from the code images  20  in the first row. In the third row from the top, the code images  20  are place, being flipped left and right in relation to the first row. In the fourth row from the top, the code images  20  of the tilted posture are rotated 45° counter-clockwise from the proper posture, as in the second row, and are placed at a designated spacing, i.e., half-spacing offset from the code images  20  in the third row. The number of code images  20  in the row or the number of rows can be set appropriately. However, when taking a close-up photograph by having the lighting-skirt section  938  butted against the picture section  914 , the layout rules (including the number of rows) for the code image  20  should be defined so that at least one code image  20  is included in a photographed image. This is for the purpose of understanding the photographed position and the photographed angle on the basis of the code image  20  in the photographed image. It is preferable to have at least two code images  20  in a photographed image because the photographed position can be more accurately computed by identifying more than two code images  20 . 
         [0056]    Because each code image  20  supports unique information and some of code images  20  are arranged in the tiled posture, it is possible to know which portion of the picture image of the picture section  914  is being photographed by identifying and decoding the code image projected on the image photographed by the camera module  955 . In other words, it is possible to know the photographed position as well as the center-position coordinates of the photographed image in the picture-image coordinate system. 
         [0057]    The code pattern (the code information) of the printed code image  20  contains unique information for each page  912 , that is, for each picture section  914 , the position information in the picture section  914 , and the information indicating in which direction the code image  20  is printed with respect to the picture section  914 . Additionally, the code image  20  itself has the direction. Therefore, from the photographed code image  20 , it is possible to know which picture section  914  and which position in the picture section  914  the camera module  955  is photographing in terms of rough position and angle (clockwise/counter-clockwise rotation angle with respect to facing the page  912 ). Also from the distance between two or more photographed code images, it is possible to know which detailed position in the picture section  914  is being photographed. 
         [0058]    The purpose of the invisible print section is to enable the identification of the photographed position in the picture image based on the photographed image when taking a close-up picture image using the camera module  955 . In other words, it is intended to provide the ability to identify the photographic position or the range in the picture image, or the identification of the representative position for use in defining the applicable range. 
         [0059]    Therefore, the configuration of the invisible print section need not be limited to what is described in this embodiment, and, for example, the configuration can be in such a way that the identification information is defined by the dot distribution. Additionally, it can consist of code images or can be a dot distribution drawn with normal visible ink. Alternatively, if the content of the picture image of the visible print section photographed using the camera module  955  is successively identified using the image-pattern recognition, it can be configured to identify the photographic position or the range, or it can be the representative position for defining the applicable range. In this case, the invisible print section, the infrared transmission filter, the infrared light source and others can be eliminated. It is ideal. 
         [0060]      FIG. 4  is an explanatory view of an image display example on the handy loupe-type device  930 . 
         [0061]    The user holds the handle  936  of the handy loupe-type device  930  as if to observe an insect with the loupe, and places the handy loupe-type device  930  on the picture section  914  in such a way that the edge of the lighting-skirt section  938  (see  FIG. 2 ) touches the page  912 . Then, the user peers into the window  940 . 
         [0062]    The handy loupe-type device  930  successively takes photographs of the page  912  with the camera module  955 , detects the code images  20  in the photographed images, and analyzes the detected code images  20 . Then, from the code images  20  in the photographed image, it identifies which picture section  914  is being photographed, which position in the picture section  914  is being photographed and from which angle it is being photographed. 
         [0063]    As described earlier, the IC memory  952  of the handy loupe-type device  930  contains, in memory, the image data, which is the same as the image data of all picture sections  914 , so that any image of the picture section  914  can be displayed in the display section. The handy loupe-type device  930  extracts from the IC memory  952  the partial image W 2  of the picture in the picture section  914  currently being photographed, doing so by matching the range with the photographed range, and displays the partial image W 2  on the touch panel  942 . In other words, the image of the picture section  914  being photographed will not be displayed on the touch panel  942  of the handy loupe-type device  930 . Instead, through the touch panel  942 , the user peering into the window  940  will see the partial image W 2  of the of the picture section  914  where the handy loupe-type device  930  is touching. In the example shown in  FIG. 4 , the partial image W 2  of the woods is displayed because the handy loupe-type device  930  is touching the woods at the upper-left area of the image. If the handy loupe-type device  930  is slid, the partial image W 2  being displayed will also be scrolled to tack the change. As far as the user is concerned, the user feels as if the touch panel  942  is the lens of the loupe. 
         [0064]    Furthermore, in this embodiment the partial image W 2  extracted from the IC memory  952  needs not totally match the content of the image itself as long as the contour of the partial image W 2  matches the contour of the image being photographed. For example, it is acceptable to have the partial image W 2  colored differently from the image being photographed, or to have images added for special effects. By making the partial image different from the image being photographed, the display becomes more interesting and the attractiveness of the handy loupe-type device  930  is enhanced. 
         [0065]    Furthermore, this may be a repetitive explanation, but the photographed image itself will not be displayed on the touch panel  942  of the handy loupe-type device  930 . The partial-image displayed on the touch panel  942  is the portion of the picture-image data stored in the IC memory  952  corresponding to the photographed range identified from the photographed image. As in this embodiment, only the picture-image data stored in the IC memory  952  is displayed in the display section, and the code images, which would normally be displayed in the display section, will not be displayed in the display section. Therefore, it is not necessary to worry about code images being projected in the display section. This will allow the use of a simple configuration for the picture images of the picture section and will enhance the freedom of designing code images. 
         [0066]      FIGS. 5 and 6  are an explanatory view of an image display example on the handy loupe-type device  930  when the specific range  32  is included in the photographed image. 
         [0067]    When it is judged that all or a part of the specific range  32  is included in the photographed image taken by the camera module  955 , the handy loupe-type device  930  displays, on a partial image, the “special image” related to the observation object  30  corresponding to the specific range  32 . In other words, when it is judged that the photographed position satisfies the designated position condition, a special image will be displayed on the partial image. 
         [0068]    The “special image” is configured with a single or a plurality of image elements expressing different appearances of the observation object  30  in the picture image being photographed. The definition data of the special image corresponding to the specific range  32  is stored in advance in the handy loupe-type device  930 . The image-element data for each “display condition” is stored in the definition data. In this embodiment, an image element configuring the special image can be animation (video) or a still image. Depending on the method of setting the “display condition”, there are two types of special images in this embodiment. 
         [0069]    In the example of  FIG. 5 , the “display condition” is the type in which the elapsed time is set, starting with the first time the specific range  32  is photographed. 
         [0070]    In the example of  FIG. 5 , the observation object  30   a  at the right side of the picture section  914  is drawn with the potted plant and the character depicting the rabbit with eyebrows that is nurturing the plant, but the potted plant has no bud yet. During the first day and second day from the time the specific range  32   a  of the observation object  30   a  is first photographed, the no.  1  image element W 41  that animates the rabbit watering the pot is selected as the special image and is displayed on the touch panel  942 . During the elapsed time of the third day to fifth day, the no.  2  image element W 43  animating the plant budding is selected and displayed. During the elapsed time of the sixth day to eighth day, the no.  3  image element W 46  depicting the plant having buds is selected and displayed. For the elapsed time of the ninth day and beyond, the no.  4  image element W 49  depicting the flower blooming is selected and displayed. In this explanation, the special image is comprised of 4 types of image elements, however additional image elements can be prepared such as scenes in-between the elapsed time presented or scenes beyond the no.  4  image element W 49  (for example, the withered flower forming seeds, the overall plant wilted away). 
         [0071]    In the example of  FIG. 6 , the current date and time being photographed is set as the “display condition”. For example, the season, month, day of the week, date, time frame, time of the day, holiday identification (such as Children&#39;s day), the summer recess, and Christmas period can be appropriately set as the display condition. Then, the image element of the special image corresponding to the display condition of the current time is selected and displayed. 
         [0072]    In the example of  FIG. 6 , the observation object  30   b  at the left side of the picture section  914  is drawn with the potted plant of morning glory and the character depicting the spotted rabbit that is watching the plant, but the flower in the pot is not blooming. If the time of the day when the user is using the handy loupe-type device  930  is between 6 pm and 5 am next morning, then the no.  1  image element W 61  (the same content as the photo being photographed by the camera module  955 ) corresponding to this time frame is displayed. However, if the time when the user is using the handy loupe-type device  930  falls between 5 am and 6 pm, the no.  2  image element W 62  (the scene of flower blooming) corresponding to this time frame is displayed. 
         [0073]    In this explanation, the special image is comprised of two types of image elements corresponding to the specific range  32   b,  however additional image elements can be prepared for multiple time frames such as scenes in-between the time frames presented or scenes beyond the no.  2  image element W 62  (for example, the scene of closed flower pedals after sunset). 
         [0074]    The handy loupe-type device  930  stores the image display history of the special images as displayed in  FIGS. 5 and 6 , and the user can re-display any special-image displayed before at any time. This is called the “record display function”, but because the expected users are children, it may be more appropriate to call it as the “observation pictorial guide mode”. 
         [0075]      FIG. 7  is a view that illustrates a screen display example in the observation pictorial guide mode. 
         [0076]    If the designated record display start time operation is input at the operation section  934  or the touch panel  942 , the handy loupe-type device  930  will display the record-display screen W 8 . The record-display screen W 8  contains the menu-display section  40 , the specified-position display section  41 , and the record-display section  42 . 
         [0077]    In the menu-display section  40 , the scrollable thumbnail  43  of the special images displayed in the past are displayed sorted by the observation objects  30 . The user slides the thumbnail  43  of the special image that he wants to display to the specified-position display section  41 . 
         [0078]    The handy loupe-type device  930  displays the scrollable special images, that were displayed in the past, corresponding to the thumbnail  43  that is slid to the specified-position display section  41 , at the record-display section  42  sorted by image elements. If a touch operation is detected at the image element of the record-display section  42 , the image element will be expanded in display as shown in the screen display example W 10 . 
         [0079]    On the record-display screen W 8 , the record-display termination operation icon  44  is provided. If this icon is touched or a designated operation is performed at the operation section  934 , the display of the record-display screen W 8  can be terminated. Furthermore, in this embodiment the voice output section can be provided on the handy loupe-type device  930 . The handy loupe-type device  930  will be more appealing to the users if the voice output is provided accompanying the image display in the display section. 
         [0080]    Explanation of Functional Configuration 
         [0081]      FIG. 8  is a functional block diagram that illustrates an example of the functional configuration of the handy loupe-type device  930 . 
         [0082]    The handy loupe-type device  930  of this embodiment comprises the operation input section  100 , the imaging section  102 , the control section  200 , the image-display section  372 , and the memory section  500 . 
         [0083]    The operation section  100  outputs the operation input signal to the control section  200  according to various input operation performed by the player. The operation input signal can be generated by, for example, the push switch, joy stick, touch pad, track ball, acceleration sensor, gyro, etc. In the example given in  FIG. 2 , the operation switch  935  or the touch panel  942  falls under this. 
         [0084]    The imaging section  102  outputs the photographed image data to the control section  200 . In the example of  FIG. 2 , the camera module  955  falls under this. 
         [0085]    The control section  200  is implemented, for example, with the SoC or the microcontroller IC that integrates the CPU, GPU and semiconductor memories on a single semiconductor element, and controls input and output of data between various functional sections including the operation input section  100 , the imaging section  102  and memory section  500 . It performs various computational processes based on designated program and data, the operation input signal from the operation input section  100 , image data from the imaging section  102 , and controls integrally the action of the handy loupe-type device  930 . In the example of  FIG. 2 , it is included in the control board  950 . 
         [0086]    The control section  200  in this embodiment contains the invisible-code identification section  202 , the code identification section  204 , the photographed-position identification section  206 , the partial-image display control section  208 , the special-image display-control section  210 , the special-image display history memory control section  220 , the record-display control section  222 , the clock section  226  and the image generation section  272 . 
         [0087]    The invisible-code identification section  202  analyzes the image data photographed by the imaging section  102 , detects the code image  20  projected in the image, and identifies the code pattern or the orientation of code image  20 . 
         [0088]    The photographic picture identification section  204  identifies the type of the picture section  914  (which one of a plurality of picture sections  914 ) from the code image  20  identified by the invisible-code identification section  202 . 
         [0089]    The photographed-position identification section  206  identifies the relative photographed position in the image of the picture section  914  being photographed. 
         [0090]    More specifically, the photographed-position identification section  206  identifies the position in the picture section  914  from the code pattern identified by the invisible-code identification section  202 , and identifies the orientation of the photograph with respect to the picture section  914  based on the orientation of the code image  20  projected. Based on this identified position and orientation, the photographed position (referred to as the photographed position or photographed range) is derived. Additionally, in this embodiment the focus distance of the imaging section  102  can be judged as fixed by the lighting-skirt section  938 , the photographed position can be derived from the identified position and orientation. 
         [0091]    The partial-image display control section  208  controls the image-display section  372  to display the partial image W 2  (see  FIG. 4 ) of the picture section  914  corresponding to the photographed position identified by the photographed-position identification section  206 . 
         [0092]    When the photographed position identified by the photographed-position identification section  206  satisfies the position condition for the display of the designated special image, the special-image display-control section  210  controls the image-display section  372  to display, on the partial image W 2 , the special image corresponding to the picture section  914  identified by the photographic picture identification section  204 . Furthermore, in this embodiment in order to variably control the special images based on the clocking information, the image-selection section corresponding to the current time and date  212  and the image-selection section corresponding to the elapsed time  214  are provided as the image-selection section corresponding to clocking information. 
         [0093]    In this embodiment, it is judged that the position condition is satisfied when the specific range  32  surrounding the observation object  30  is included in the photographed image (conversely when the center position coordinates of the photographed image is within the specific range  32 ). Then, the image-selection section corresponding to the current time and date  212  selects the image element that will be the special image to be displayed corresponding to the current time and date (see  FIG. 6 ). The image-selection section corresponding to the elapsed time  214  selects the image elements that will be the special images to be displayed corresponding to the elapsed time starting with the first time/date the position condition is satisfied (the first time/date the observation object  30  becomes the target of photographing) to now (see  FIG. 5 ). 
         [0094]    The special-image display history memory control section  220  controls the memory section  500  to store the history of the special images displayed by the image-display section  372 . 
         [0095]    The record-display control section  222  controls the image-display section  372  to display the record-display screen W 8  (see  FIG. 7 ), and to display the special images displayed in the past based on the history stored by the special-image display history memory control section  220 . 
         [0096]    The clock section  226  clocks the time and date. The clock section  953  in  FIG. 2  falls under this. 
         [0097]    The image generation section  272  is implemented by, for example, the processors such as GPU and the digital signal processor (DSP), the programs and circuits such as the video signal controller and the video codec, and the semiconductor memories for drawing frames such as the frame buffer. 
         [0098]    In accordance with controls and instructions from the partial-image display control section  208 , the special-image display-control section  210  and the record-display control section  222 , the image generation section  272  creates one sheet of an image within the designated frame time ( 1/60 second for example), and outputs the image signal of the generated image to the image-display section  372 . 
         [0099]    Based on the image signals input from the image generation section  272 , the image-display section  372  displays various images. The touch panel  942  in  FIG. 2  falls under this. 
         [0100]    The memory section  500  stores in memory various programs and data for the control section  200  to implement the various functions in order to integrally control the handy loupe-type device  930 . Additionally, it is used as the working area of computation processes of the control section  200 , and it stores temporarily in memory the various computation results of the control section  200  executing various programs, the input data from the operation input section  100 , and image data input from the imaging section  102 . These functions can be implemented by, for example, the semiconductor memories such as RAM or ROM, the electromagnetic disk such as a hard disk, and the optical disk such as CR-ROM or DVD. The IC memory  952  or the semiconductor built in the SoC  951  mounted on the control board in  FIG. 2  fall under this. 
         [0101]      FIG. 9  is a diagram that illustrates programs and data stored in the memory section  500  of this embodiment. In the memory section  500  of this embodiment, the system program  501 , the handy device-control program  502 , the picture-section identification definition data  510 , the picture-section definition data  520 , and the special-image definition data  530  are stored. In addition, as needed, the photograph target picture section ID  550 , the photographed position definition data  552 , the special-image display history data  560 , the timer and counter for clocking, various flags and other information are stored in memory. 
         [0102]    The system program  501  is the basic program for the handy loupe-type device  930  to implement the basic function as a computer such as the input/output function. 
         [0103]    The handy device-control program  502  allows the control section  200  to implement various functions such as the invisible-code identification section  202 . 
         [0104]    The picture-section identification definition data  510  is prepared separately for each picture section  914  of the main body  910 . Each picture-section identification definition data  510  stores information of the various code images included in the picture section  914  (such as the code pattern, the position embedded (printed) in the picture section, and the orientation), and the picture section ID to identify the picture section  914 . Of course, other data can be appropriately stored, such as information of layout rules when changing the layout rules of the code images separately for each picture section  914 . 
         [0105]    The picture-section definition data  520  is prepared separately for each picture section  914  of the main body  910 , and defines each picture section  914 . Each picture-section definition data  520  contains, as shown in  FIG. 10  for example, the picture section ID  521 , the picture-image data  522 , and the special-image ID  524  linked to the corresponding special-range definition data  523 . Of course, other data can be stored appropriately. 
         [0106]    The picture-image data  522  has the same image coordinate system as the corresponding picture section  914 , and is the data to display the same content. In this embodiment, this is the two-dimensional image data. 
         [0107]    The special-range definition data  523  defines the specific range  32  separately for each observation object  30  set in the corresponding picture section  914  (see  FIG. 3 ). The specific range  32  of this embodiment is a rectangular region, and therefore the coordinate of each of the four corners of the rectangular region in the image coordinate system of the picture-image data  522  will be stored. 
         [0108]    The special-image ID  524  indicates the special image that would correspond to the observation object  30  and its specific range  32 . 
         [0109]    The special-image definition data  530  shown in  FIG. 9  is prepared for each special image and defines the configuration of the special image. Each special-image definition data  530  includes, as shown in  FIG. 11  for example, the special-image ID  531 , the image-element display-based point coordinate  535 , the image-element ID  541  linked to the corresponding display condition  540 , and the image-element data  543 . Of course, any other data can be stored appropriately. 
         [0110]    The image-element display-based point coordinates  535  define the standard position for the display of the special image in the image of the picture section  914 . 
         [0111]    The display condition  540  is for the display of the corresponding image-element data  543 . As described earlier, in this embodiment there are two types of display conditions. One type sets the elapsed time starting with the first time/date when photographed (see  FIG. 5 ). The second type sets the condition of time/date for which the current photographed time/date is compared (see  FIG. 6 ). 
         [0112]    The image-element data  543  defines the image element, which has the same size as the specific range  32 . The no.  1  image element W 41  through no.  4  image element W 49  in  FIG. 5 , and no.  1  image element W 61  and no.  2  image element W 62  in  FIG. 6  are defined by this data. When displayed based on the image-element display-based point coordinates  535 , the image element just covers the specific range  32 . 
         [0113]    The photograph target picture section ID  550  in  FIG. 9  stores the picture section ID of the picture section  914  that is currently being photographed. 
         [0114]    The photographed position definition data  552  stores the information for use in defining the relative photographed position, that is to say the photographed portion, in the image of the picture section  914  that is currently being photographed. The photographed position definition data  552  of this embodiment contains the photographed image center position coordinate  554 , the rotational angle  556 , and the range four corners coordinate list  558  that indicates the position coordinates of four corners of the photographed range. 
         [0115]    In this embodiment, the handy loupe-type device  930  is used in which the lighting-skirt section  938  touches the page  912 , and it is maintained in the designated relative posture in such a way that the light axis L of the camera module  955  will be perpendicular or almost perpendicular with respect to the printed surface of the picture section  914 . Therefore, the rotational angle  556  will be limited to the rotational components around the perpendicular axis (the roll angle around the light axis L). However, in the configuration which does not have the lighting-skirt section  938 , the relative posture with respect to the page  912  is not necessarily constant. Therefore, in addition to the roll angle around the light axis L, the pitch angle and the yaw angle may be added. 
         [0116]    Whenever the special image is displayed, the special-image display history data  560  coordinates with the display time/date  561  for time stamping, and stores the special-image ID  563  of the displayed special image and the image-element ID  565  of the special image. All history in the special-image display history data  560  can be erased when a designated history delete operation is performed. 
       Explanation of the Flow of the Process 
       [0117]      FIG. 12  is a flow chart describing the flow of the process in the handy loupe-type device  930 . 
         [0118]    The control section  200  judges whether or not the code image  20  is included in the image photographed by the camera module  955  (step S 2 ). 
         [0119]    If it is included (YES in step S 2 ), the control section  200  identifies the type of picture section  914 , which is being photographed, based on the code pattern of the code image  20  in the photographed image (step S 4 ). Then, the picture section ID of the identified picture section  914  will be set in the photograph target picture section ID  550  (see  FIG. 9 ). Next, the control section  200  specifies the photographed position in the image of the identified picture section  914  (step S 8 ). More specifically, based on the code pattern and the position and orientation in the photographed image in which the code image  20  is projected, the control section  200  specifies which portion of the picture section  914  is being photographed and the photographed angle (roll angle: at a clockwise or counter-clockwise angle with respect to the photographed direction), and then it computes the coordinates of the four corners of the photographed range. 
         [0120]    Then, based on the picture-image data  522  of the picture-section definition data  520 , which has the picture section ID  521  (see  FIG. 10 ) matching the photograph target picture section ID  550 , the control section  200  controls the touch panel  942  to display the partial image corresponding to the photographed position (step S 10 ). 
         [0121]    If all or a portion of the specific range  32  is included in the photographed image (the photographed range), the position condition for the display of the special image is judged as satisfied (YES in step S 32 ), and then the control section  200  selects the special image corresponding to applicable specific range  32  (step S 32 ), and displays it on the screen, being overlaid on the partial image being displayed in step S 10 . 
         [0122]    More specifically, for each specific range  32  defined by the special-range definition data  523  (see  FIG. 10 ), it is judged whether all or a part of the specific range  32  is included in the photographed range indicated by the photographed position definition data  552 . 
         [0123]    If included, the special-image definition data  530 , which matches the special-image ID  524  corresponding to the applicable special-range definition data  523 , will be referenced (see  FIG. 11 ). Then, the applicable conditions in the display condition  540  of the referenced special-image definition data  530  will be searched, and the image-element data  543  corresponding to the applicable display condition  540  will be selected and read out. Based on the image-element display-based point coordinates  535 , the image element will be displayed on the partial image that is being displayed on the screen in step S 10 . As described earlier, the image element defined by the image-element data  543  has the same size as the specific range  32  surrounding the observation object  30 , and is displayed on top of that. Consequently, in the screen display of the touch panel  942  it appears as if the state of the observation object  30  has changed. Next, the control section  200  stores in memory the display history of the special image (step S 36 ). 
         [0124]    That is to say, the current time/date is set as the new display time/date  561  in the special-image display history data  560  (see  FIG. 9 ). In the image-element ID  565  corresponding to the new display time/date, the image-element ID  541  of the image-element data  543  displayed in step S 34  is stored (see  FIG. 11 ). The special-image ID  531  is set to the special-image ID  563  (see  FIG. 11 ). 
         [0125]    When the start-operation for the designated record display is detected (YES in step S 50 ), the control section  200  controls the touch panel  942  to display the record-display screen W 8  (see  FIG. 7 ) (step S 52 ). 
         [0126]    Then, the special images displayed in the past are displayed by the record-display section  42  in response to the selection operation at the menu-display section  40  (step S 54 ). More specifically, the image-element ID  565  corresponding to the special-image ID  563  having the same ID as the image-element data  543  corresponding to the thumbnail placed on the designated position (on the specified-position display section  41 ) will be read out and displayed by the record-display section  42 . 
         [0127]    When the termination-operation of the designated record display is detected (NO in step S 56 ), the display of the record-display screen W 8  will be canceled (step S 58 ) 
         [0128]    On the other hand, if the code image  20  is not projected in the photographed image in step S 2  (NO in step S 2 ), it is judged that the photograph is not taken properly (it is photographed without the lighting-skirt section  938  touching the picture section  914 ) and the photographed image is deleted, and then a designated display is shown on the screen informing the photograph is not taken properly and therefore nothing is displayed on the screen (step S 60 ). 
         [0129]    The information presentation program related to this invention operates the computer equipped with the imaging section (the camera module  955 , for example) and the display section (the touch panel  942 , for example). This information presentation program allows the computer to function as the display image data memory means, thereby storing in memory the display-image data (the picture-image data  522 , for example); the photographed-position identification means that identifies the photographed position in the information section based on the image recognized by the imaging section when the imaging section recognizes the image listed in the information section (the picture section  914 , for example); and the partial-image display control means that lets the display section control the display of the partial image based on the partial-image data that is generated from the display-image data memorized in the display-image data memory means based on the photographed position identified by the photographed-position identification means. In this information presentation program, the contour of the partial image matches the whole or a part of the contour of the image recognized by the imaging section. 
         [0130]    In this embodiment, when the picture image in the picture section is observed (photographed) using the handy device, the partial image corresponding to the range being photographed within the picture image is displayed in the display section of the handy device. For example, if the picture image is a photograph of an insect, one can experience a pseudo-observation as if one is observing an inset with the handy device. Also by displaying only the image data stored in the memory section, the code image, which is normally displayed in the display section, will not be displayed in the display section. Therefore, it is not necessary to worry about code images being projected in the display section. This will enhance the freedom of designing the picture image and code image in the picture section. 
         [0131]    In this embodiment, it is possible to display the special image, which is not drawn on the picture section, on the image displayed in the display section of the handy device. In other words, it is possible to provide an experience of “seeing on the screen the object that cannot be seen with the naked eye.” As described earlier, this type of experience gives a strong impression. 
         [0132]    Even though this is a pseudo-experience, this will impress children in terms of joy of “observing”, and will be very effective in the intellectual training of children. 
         [0133]    Furthermore, in this embodiment the content of the special image can be varied according to the time/date of observing (photographing) the picture section by the handy device, and depending on the elapsed time from the time starting the observation. For example, if the special images that can only be seen during a designated time frame (early morning, for example) are prepared and if a child is able to see them, then the child may learn the importance of keeping the observation time. 
         [0134]    Furthermore, in this embodiment one can see the observation record later and can experience the act of pseudo-observing. 
         [0135]    Furthermore, in this embodiment the content of display of the display section varies depending on the observing (photographing) position in the picture section. Therefore, this may build up enthusiasm in children to observe from corner to corner of the picture section. 
         [0136]    Furthermore, in this embodiment the photographed position can be derived from the relative position relationship between code images. This method has much less computational load than the configuration in which the photographed position is derived by analyzing portion to portion of the picture image using image-recognition technology. In implementing the control section, it is not necessary to employ the computational device with high processing capability, and the manufacturing cost of the handy device can be reduced. 
         [0137]    Furthermore, in this embodiment by designing the handy device resembling a “loupe,” which is a typical item for observation, it enhances the ambience of the observation act even though it is a pseudo-experience. 
         [0138]    As described above, in this embodiment when the user places the handy loupe-type device  930  above the picture section  914  as if to observe the target with the loupe and peers into the window  940 , the user can see the scene of the observation target  30  changing by the elapsed time or the particular time/day. Thus, this embodiment can offer a pseudo-experience in which new discoveries are made by observing over time or observing at a different time/day. The content of the observation target  30  can be set to various fields and topics ranging with, understandably, the natural science field to the home-cooking process. Thereby, users can be offered pseudo-experience over a wide range of areas. 
         [0139]    Another variation 
         [0140]    It should be noted that embodiments of this invention are not limited to the aforementioned embodiments, and configuration elements can appropriately be changed, added or deleted. 
         [0141]    For example, the configuration of the handy loupe-type device  930  is not limited to the dedicated design device as described in the above embodiment. It can be implemented by storing the handy device-control program  502  (see  FIG. 9 ), the picture-section identification definition data  510 , the picture-section definition data  520  and the special-image definition data  530  into memory of a portable electronic device such as a smart phone or a tablet, and by executing the handy device-control program  502  as an application. However, in this configuration, the part equivalent to the lighting-skirt section  938  cannot be prepared. Therefore, it can be implemented by controlling to display the image or the special image of the picture section  914  only when taking a designated close-up photograph (when the photo distance is appropriate). More specifically, the process steps beyond step S 6  are executed only when the code image  20  is correctly identified in step S 2 . Certainly it is acceptable to provide, separately to the portable electronic device, a detachable part equivalent to the lighting-skirt section  938 , which can be worn during use. 
         [0142]    Additionally, in the above embodiment the example of the toy system meant for children is explained, but it should not be so limited. For example, it is possible to apply to the information presentation system that executes content for adults.
