  FIG. 31 is an explanatory diagram showing the configuration of the wireless communication circuit 71 in the electronic camera. The wireless communication circuit 71 is backed by the electromagnetic shield film 79 (the direction opposite to the photographing optical axis direction = the photographer's direction) and the bottom surface. And the upper and left and right sides are surrounded. Therefore, the wireless communication circuit 71 is easy to communicate with the portable device 160 possessed by the subject located in the photographing direction of the camera, can reliably collect subject information, and possesses other subjects than those in the photographing optical axis direction. Since it is difficult to communicate with existing mobile devices, it is possible to avoid collecting unnecessary information other than the subject as much as possible. FIG. 32 is a diagram showing the directivity of communication of the wireless communication circuit 71. The directivity of the electronic camera 100 is strong in the front direction (the direction of the optical axis 40), and the directivity in the back direction is weak.

  As described above, by providing the wireless communication circuit 71 with a strong directivity in the shooting direction of the camera with the configuration shown in FIG. 31, it is possible to increase the probability of communication with the electronic device held by the subject. The directivity can be adjusted by the antenna configuration in addition to the electromagnetic shield film.

  In the wireless communication process of FIG. 16, the electronic camera 100 communicates with surrounding electronic devices and collects subject information at the time of shooting, but the subject information is stored in the electronic camera that has shot from the subject electronic device side before and after the shooting. You may make it transmit. For example, as shown in FIG. 33, a mobile phone 160 held by the subject stores and saves personal information of the user who holds the mobile phone 160 by attaching a UIM card or the like. The mobile phone 160 includes a display screen 161 and operation buttons 162. When a person who is a subject transmits personal information of the person to the electronic camera side, first, when the operation button 162 of the mobile phone 160 is operated, the mobile phone 160 enters a personal information transmission mode and transmits subject information to the electronic camera. When the transmission is completed, the display screen 161 displays a transmission destination electronic camera and a message indicating that the transmission is completed in FIG. In this way, since it is possible to determine whether or not personal information can be transmitted on the subject side, personal information can be prevented from being inadvertently leaked.

  In the detection of the position of the subject in the screen shown in FIG. 18, the position information of the electronic camera and the position information of the electronic device detected by GPS are used, but the position of the subject in the screen is detected by other methods. May be. FIG. 35 shows a narrow directivity wireless antenna 75 used as a communication antenna of the wireless communication circuit 71 (the directivity 43 has extremely strong directivity in one direction 42 as shown in FIG. 36). It is an example in the case of detecting a position in a photographing screen. The detailed configuration of such a small directional antenna is disclosed in Japanese Patent Laid-Open No. 2000-278037.

  The electronic camera 100 includes a narrow directional wireless antenna 75 and a drive unit 76 that mechanically scans and changes the direction of the narrow directional wireless antenna 75. At the time of radio communication processing at the time of photographing, the CPU 50 communicates with the subject on the screen by the radio communication circuit 71 while driving the narrow directional radio antenna 75 to scan the inside of the photographing screen by the driving unit 76. Collect data. Thereby, the scanning position (= in-screen position information data) of the narrow directivity wireless antenna 75 can be associated with the subject information data.

FIG. 37 is a detailed flowchart of the radio communication processing subroutine using the narrow directional radio antenna 75. When the subroutine is started in S40, it is checked in S411 whether the shooting mode is set, and if not in the shooting mode, the process returns in S419. In the shooting mode, the scanning position of the narrow directivity wireless antenna 75 is initialized in S412. The screen size is determined by the focal length information of the photographing lens and the effective screen size of the CCD. In step S413, the wireless communication means 71 can be used to transmit electronic information around the electronic camera 100 (a mobile phone held by the person who is the subject or the vicinity of the historical site, and the tourist information of the historical site can be transmitted by wireless communication. Attempt to communicate wirelessly with an electronic tourist guide device. If communication is not established in S414, the process proceeds to S417.
When the communication is established, subject information data is acquired by wireless communication from the electronic device of the communication partner with whom the communication is established in S415. In S416, the in-screen position information of the subject information data is used as the scanning position information of the narrow directivity wireless antenna 75. In S417, the scanning position of the narrow directivity wireless antenna 75 is updated. In S418, it is checked whether or not the scanning position of the narrow directivity wireless antenna 75 is the end position. If it is not the end position, the process returns to S413 and the above operation is repeated. If it is the end position, the process returns in S419.

FIG. 38 shows a display example of the home screen in the information display mode, and no icon is displayed on the left screen 21 unlike FIG. When the user touches a person or building displayed on the left screen, the touch position is detected by the touch tablet 66, and subject information having in-screen position information data corresponding to the touch position is displayed on the right screen 22 as shown in FIG. Is displayed. An arrow mark 44 is displayed at the position of the subject on the left screen 21 corresponding to the subject information. In this way, the image data reproduced and displayed on the left screen 21 can be viewed without any disturbing icons, and if the subject interested in the left screen 21 is touched, the image data remains displayed on the left screen 21. The subject information can be viewed on the right screen 22 and the relationship between the subject information and the subject on the image can be confirmed. In this way, it is also possible to display subject information directly from the reproduction mode by integrating the information display mode and the reproduction mode.

  Also, as shown in FIG. 40, when the contour of the subject image reproduced and displayed by image analysis is extracted and the user touches a region near the contour (region 46 near the person 45 in FIG. 40), the region is displayed. The subject information corresponding to the in-screen position information data included in 46 may be displayed on the left screen 21. In this way, the subject information of the person can be displayed even when the face part other than the position where the electronic device that sent the subject information to the electronic camera is located, for example, is touched.

  FIG. 41 is a detailed flowchart when a new process is added between S801 and S802 of the information display mode subroutine shown in FIG. This new process is a process of transplanting subject information of a similar image file having subject information into an image file having no subject information.

After displaying the home screen in S801, image analysis of the image data reproduced and displayed on the left screen 21 is performed in S811 to identify main subjects (subjects such as people and buildings that occupy a relatively large area in the screen). In step S812, it is checked whether or not subject information having in-screen position information data exists in the main subject region. If present, the process proceeds to step S802. If it does not exist, an image file having the same shooting date / time data as the shooting date / time data of the image data reproduced and displayed in S813 is searched and extracted in the memory card 104. Next, image data of the image file is subjected to image analysis, and image data having a subject similar to the main subject in the image data currently reproduced and displayed is further extracted. Next, it is checked whether or not the position information in the screen is attached to the similar subject in the extracted image data, and if it is attached, the subject information is used as subject information of the main subject of the image data currently reproduced and displayed. The position information in the screen corresponding to the position in the screen of the main subject specified by the image analysis is added, and the image file of the image data currently reproduced and displayed is updated.

  In S814, shooting position information data, shooting posture information data, and focal length information data are read out from the image file including the image data that is currently reproduced and displayed, and the map database on the Internet and the image analysis result in S813 according to the information data. Identify the main subject. For example, if a triangular mountain-like object is shown on the screen taken from the vicinity of Lake Yamanaka toward the south, it is identified as Mount Fuji.

  When a main subject is identified, the main subject name is searched for on the Internet using the keyword as a keyword, access information of a home page on which explanation of the main subject is obtained, and the main subject screen determined by image analysis is obtained. The position information in the screen according to the position is added, and the image file of the image data currently reproduced and displayed is updated.

  After the subject information is transplanted from another image file or the Internet to the image file having no subject information as described above, the process proceeds to S802. In this way, even if the subject information could not be acquired at the time of shooting (such as when there is no sightseeing guide device that supplies subject information wirelessly in the vicinity of the electronic camera with a landscape image, etc.), the image data was reproduced in the information display mode. In this case, information about the subject can be displayed. Note that the range of image files searched in S813 is not limited to the same shooting date and time. For example, a search may be made from a predetermined number of image files taken before and after an image file having no subject information. In S814, the camera automatically identifies the subject from the shooting position information data, the shooting posture information data, and the focal length information data, and downloads the specified subject information from the Internet. However, the user browses the image data. The subject may be specified, information on the specified subject may be input or downloaded from the Internet, and the image file may be updated by pasting the information on the subject position on the screen.

  FIG. 42 is another conceptual diagram of an electronic camera to which the present invention is applied and an electronic image communication system using the electronic camera. In the electronic image communication system of FIG. 2, personal information data stored in the UIM card 170 attached to the mobile phone 160 is electronically transmitted when the electronic camera 100 and the mobile phone 160 possessed by the user perform short-range wireless communication. 42, when the wireless tag (non-contact IC card) storing personal information data comes close to the electronic camera 100 having a built-in non-contact wireless reading unit in the electronic image communication system of FIG. Personal information data is automatically read into the electronic camera 100 from the wireless tag.

  In the above embodiment (FIGS. 1 and 11), wireless communication is performed between the electronic camera and the portable device held by the subject when the image data is captured, and subject information (including position information) is stored in the electronic camera. Since it is automatically transferred, no special operation is required to acquire the subject information, and the position information of the subject at the time when the image data was taken can be acquired. When obtaining information data, it is possible to obtain a position that accurately corresponds to the actual position on the screen. If the subject position information acquisition timing is close to the subject photographing timing (desirably within about 1 second), a position accurately corresponding to the actual position on the screen can be obtained.

  In the above-described embodiment (FIGS. 1 and 11), information related to a subject appearing on a screen that is of interest when image data is reproduced and displayed according to the in-screen position information. It is possible to browse simply and quickly by simply touching an icon or subject displayed on the screen.

  In the above embodiment (FIGS. 1 and 15), since short-range wireless is used when acquiring subject information from the subject by wireless communication, the probability of communication with a subject existing in the vicinity of the electronic camera is increased, and It is possible to eliminate electronic equipment that is not related to a subject at a long distance from the electronic camera. In addition, since the signal transmission output level during wireless communication is adjusted according to the focal length of the photographic lens, wireless communication can be established reliably with the subject, and wireless communication can be established with other subjects. Can be reduced.

  In the above embodiment (FIG. 23), the image data reproduced and displayed in the reproduction mode can be transmitted to the transfer destination included in the subject information data acquired at the time of photographing the image data. It is possible to easily transmit image data to a person who has become a subject without having to listen to the address or e-mail address of the other party when taking a picture. This is especially convenient when taking group photos of a large number of people, saving the trouble of sending image data.

  In the above embodiment (FIG. 27, etc.), when displaying subject information designated by the user in the information display mode, image data showing the original subject is displayed (thumbnail image) at the same time. It is possible to intuitively grasp the relationship between the image data and the subject, and it is possible to return to the home screen immediately by designating the image data with the touch tablet 66. Therefore, it is easy to browse the subject information centering on the image data. Can be done.

When subject information is acquired by wireless communication, wireless communication with a subject can be established reliably, and the possibility of establishing wireless communication with other than the subject can be reduced.

  In the above embodiment (FIGS. 33 and 34), the subject information is transmitted to the electronic camera upon activation of the subject side, so that personal information and the like can be prevented from flowing out to the outside as necessary. .

  In the above embodiment (FIG. 37), the screen is scanned using the narrow directional wireless antenna, and the position information of the subject on the screen is collected. There is no need to provide a means, and the system can be configured at low cost.

  In the above-described embodiment (FIG. 41), the position information of the subject on the screen is detected by image analysis and the subject information is copied from the similar image file. Information can be referred to. In addition, it detects the position information of the subject on the screen by image analysis, identifies the subject by image analysis and position information, and collects subject information about the subject identified from information sources such as the Internet. It is possible to refer to subject information for a subject that could not be taken when browsing.

In the above embodiment (FIG. 42), the electronic camera is provided with a non-contact IC card (wireless tag) reading circuit, and the subject information is read in a non-contact manner from the non-contact IC card (wireless tag) possessed by the subject. Therefore, the subject is lightweight, small, and only holds a non-contact IC card that does not require a power source, and no operation is required.

Alternatively, only the position information in the screen may be detected by a two-dimensional infrared image sensor by detecting the position of an infrared point light source emitted from the electronic device, and wireless communication (radio waves) may be used for communication of subject information. In this case, the infrared point light source is turned on at the timing when the electronic device performs wireless communication.

  In the above embodiment (FIG. 25), the subject information corresponding to the touch position of the user on the screen is displayed by accessing the Internet in the information display mode, but it is not always necessary to access the Internet, and it is collected at the time of shooting. If the subject information is sufficient, only the subject information may be displayed on the screen. In this way, since it is not necessary to access the Internet when displaying the subject information, the subject information can be displayed quickly, and the user's stress awaited during browsing can be reduced.

  In the above-described embodiment (FIG. 26), the image data photographed with the predetermined photographing screen size in the information display mode is reproduced and displayed in accordance with the size of the display screen, and is displayed on the display screen designated by the user. The subject information corresponding to the position of the camera is displayed on the display screen, but it is not always necessary to match the size of the shooting screen and the display screen. The shooting screen is enlarged or reduced on the display screen. Also good. Further, the image data may be displayed on the display screen after being transformed, rotated, or the like. If the shooting screen and the display screen do not match in this way, the position specified on the display screen is coordinate-converted (enlarged, reduced, shifted, rotated, etc.) to the position on the shooting screen, and the converted position coordinates are set. Subject information is displayed based on this. In this way, it is not necessary to make the shapes of the shooting screen and the display screen congruent, the information display mode can be used in various image display devices, and when subjects are mixed in close proximity. A desired subject can be designated after enlarging the display screen.

  In the above embodiment (FIG. 27), the electronic camera has two display screens, displays the subject information of one screen in the information display mode, and displays image data including the subject on the other screen (thumbnail image). However, when the electronic camera has only one screen, the subject information may be displayed on the entire screen, and image data including the subject may be superimposed on a part of the subject information. In this way, even when there is only one display screen, the subject information and the original image data can be browsed at the same time, so the relationship between the subject information and the image data can be grasped intuitively.

As described above, in the electronic camera, the image display device, and the image display method according to the present invention, the relevant information of the subject associated with the position of the subject in the screen is added to the electronic image data and stored. When the electronic image data is reproduced and displayed, the relevant information of the subject is displayed according to the position in the screen, so that the user is interested in reproducing and displaying the electronic image data. The information related to the subject in the screen can be easily and quickly browsed in cooperation with the reproduction display of the electronic image data.
