Specifically, an image file in Exif format is generated in which image data in JPEG format is stored in the image data portion and additional information is stored in the additional information portion. The generated image file is stored in the recording medium 10A.

  Since the present invention is characterized by a reproduction operation in which a captured image is displayed on the liquid crystal monitor 111 using an image file stored in the electronic camera 10, the following description will be focused on the liquid crystal monitor 111 display.

  FIG. 2 is a view of the electronic camera 10 as viewed from the liquid crystal monitor 111 (back surface) side. In FIG. 2, a liquid crystal monitor 111 is disposed on the back of the electronic camera 10, and a zoom switch 113b, a menu switch 113c, other operation switches 113d, 113e, 113g, and a dial 113f are provided beside the liquid crystal monitor 111. The dial 113f configured in a ring shape generates a rotation operation signal corresponding to the rotation operation and a pressed position signal corresponding to the pressing operation. The determination switch 113g is disposed at the center of the dial 113f. A release button 113a is disposed on the upper surface of the electronic camera 10.

A map image is displayed on the liquid crystal monitor 111. For example, the electronic camera 10 displays, on the liquid crystal monitor 111, a map of an area corresponding to an item designated by the menu setting among the following five items.
1. 1. Map including the current location of electronic camera 10 (position calculated based on received signal from GPS device 114) 2. Last (previous) area map displayed on the LCD monitor 111 3. Map including the position (calculated based on the received signal from the GPS device 114) measured at the time of the last (previous) shooting Map of predetermined area 5. Map of area indicated by operation signal from operation member 113

  Map information necessary for displaying a map image is configured to be received from an external device via the wireless interface 116 or the external interface 112. The received map data can also be recorded on the recording medium 10A.

  In the display image of the liquid crystal monitor 111 illustrated in FIG. 2, marks 21 to 26, a pointer 31, and a frame number display 32 are displayed on the map image, respectively. The marks 21 to 26 indicate that an image photographed at a position corresponding to each mark exists in the electronic camera 10. Specifically, when an image file stored in association with positioning information corresponding to the display positions of the marks 21 to 26 is recorded in the recording medium 10A, the position (indicated by the positioning information) of the electronic camera 10 ( The mark is displayed at (shooting position).

  In addition to the normal circle mark, a mark selected from each of a plurality of types having different shapes and colors, such as a restaurant mark 21 and a heart mark 22, is displayed for each shooting position. The electronic camera 10 reads information indicating the type of mark recorded in the recording medium 10 </ b> A in association with the photographed image, and displays the type of mark indicated by the read information superimposed on the map image on the liquid crystal monitor 111.

  The display size of the mark is controlled so as to change according to the number of images photographed at the position corresponding to the mark. For example, the electronic camera 10 displays a large mark when adjacent marks overlap or when the number of images taken at the same position is large.

  The display range of the map image displayed on the liquid crystal monitor 111 (that is, the map scale ratio) changes according to the operation signal from the zoom switch 113b. The electronic camera 10 performs display control so that the scale factor is decreased (enlarged display) when the zoom switch 113b is operated to the tele side (T), and is increased (reduced display) when the zoom switch 113b is operated to the wide side (W). To do.

  The electronic camera 10 divides and displays the large mark displayed before the enlarged display into a plurality of small marks when the overlapping of adjacent marks can be eliminated by reducing the scale ratio of the map image.

  The pointer 31 is display-controlled so as to be movable within the display screen of the liquid crystal monitor 111. The electronic camera 10 moves the pointer 31 smoothly in the direction of the pressed position in response to the pressed position signal from the dial 113f. For example, when the right side of the dial 113f is pressed, the pointer 31 is moved rightward from the current display position. When the right side of the dial 113f continues to be pressed, the pointer 31 is moved further to the right side. When the right side of the dial 113f is further pressed with the pointer 31 reaching the right side of the display screen, the map image to be displayed is moved to the left. Scroll. As a result, the right side portion on which the map image is not displayed is newly displayed on the liquid crystal monitor 111.

  The electronic camera 10 similarly performs display control when the upper side, the left side, and the lower side of the dial 113f are pressed. In addition, when the diagonally upper side and the diagonally lower side of the dial 113f are pressed, display control is performed so that the map image scrolls in each direction.

  The electronic camera 10 further moves the pointer 31 when the dial 113f is rotated. In this case, the pointer 31 moves directly so as to jump between marks displayed on the liquid crystal monitor 111. For example, when the dial 113f is rotated clockwise, the electronic camera 10 moves the pointer 31 from the current display position to the nearest mark. When the dial 113f is further rotated clockwise, the pointer 31 is moved directly from the current display position onto the mark on the right side. On the other hand, when the dial 113f is rotated counterclockwise, the pointer 31 is directly moved from the current display position onto the left mark.

  When a predetermined time (for example, 0.5 seconds) elapses with the pointer 31 overlaid on the mark, the electronic camera 10 reads out a thumbnail image shot at a position corresponding to the mark from the recording medium 10A and displays the liquid crystal. Display on the monitor 111. FIG. 3 is a diagram illustrating a display image on the liquid crystal monitor 111 in this case. In FIG. 3, a pointer 31 is overlaid on the mark 23, and a thumbnail image and a shooting date / time are overlaid on the map image at a position where the mark 23 and the pointer 31 are not hidden.

  When the determination switch 113g is pressed while the thumbnail image 41 is displayed, the electronic camera 10 greatly enlarges the display size of the thumbnail image 41 to display the entire display range of the liquid crystal monitor 111 (full screen display). When the zoom switch 113b is pressed during full screen display, the electronic camera 10 returns to the thumbnail image display before the full screen display (FIG. 3).

  When the pointer 31 is overlaid on a large mark (the number of images photographed at the same position is large) for a predetermined time, the electronic camera 10 receives a plurality of thumbnail images photographed at positions corresponding to the mark from the recording medium 10A. The data is read and displayed on the liquid crystal monitor 111. FIG. 4 is a diagram illustrating a display image on the liquid crystal monitor 111 in this case. In FIG. 4, a pointer 31 is overlaid on the mark 26, and a plurality of thumbnail images 42 to 44 and shooting dates / times are overlaid on the map image at a position where the mark 26 and the pointer 31 are not hidden.

  When the determination switch 113g is pressed while a plurality of thumbnail images 42 to 44 are displayed, the electronic camera 10 selects, for example, the thumbnail image 42 and displays it in a manner different from other thumbnail images. For example, the color of the shooting date / time display portion is changed between the selected image and the non-selected image, or the selected thumbnail image is displayed in color and the non-selected thumbnail image is displayed in monochrome.

  The electronic camera 10 smoothly moves the selected position in the plurality of thumbnail images in the vertical direction in response to the pressed position signal from the dial 113f. For example, when the lower side of the dial 113f is pressed, the selected position is moved downward. When the lower side of the dial 113f continues to be pressed, the selected position is moved further downward, and the lower side of the dial 113f is further pressed in a state where the selected position has reached the lower side of the display screen (the thumbnail image 44 in FIG. 4). In this case, the thumbnail image to be displayed is scrolled upward. As a result, a thumbnail image that has not been displayed is newly displayed on the liquid crystal monitor 111, and this thumbnail image is selected.

  When the determination switch 113g is pressed while any thumbnail image is selected, the electronic camera 10 greatly enlarges the display size of the thumbnail image and displays the entire display range of the liquid crystal monitor 111 (full screen). display). When the zoom switch 113b is pressed during full screen display, the electronic camera 10 returns to the thumbnail image display before the full screen display. In this case, the selected position is maintained.

  When the zoom switch 113b is further pressed, the electronic camera 10 deselects any thumbnail image displayed in the list and returns to the thumbnail image display of FIG. As a result, the pressed position signal from the dial 113f is handled as an instruction to move the pointer 31.

<Playback mode processing>
FIG. 5 is a flowchart for explaining the flow of the playback mode process performed by the main CPU 108 of the electronic camera 10. The program according to FIG. 5 is stored in a memory (not shown) in the main CPU 108 and is activated when an operation for changing to the playback mode is performed on the electronic camera 10. The change operation to the reproduction mode is performed by, for example, a mode changeover switch 113e constituting the operation member 113.

  In step S11 of FIG. 5, the main CPU 108 determines whether or not to display map information. When the map information display is instructed by the menu setting, the main CPU 108 makes a positive determination in step S11 and proceeds to step S12. When the menu setting does not instruct the map information display, the main CPU 108 makes a negative determination in step S11. Proceed to step S22.

  In step S12, the main CPU 108 determines whether there is map data. When the map data of the area to be displayed is stored in the recording medium 10A, the main CPU 108 makes an affirmative decision in step S12 and proceeds to step S14. In this case, the map information necessary for displaying the map image is read from the recording medium 10A. On the other hand, if the map data of the area to be displayed does not exist in the recording medium 10A, the main CPU 108 makes a negative determination in step S12 and proceeds to step S13. The area for displaying the map is specified by the menu setting.

  In step S13, the main CPU 108 sends an instruction to the wireless interface 116 or the external interface 112, receives map information necessary for displaying a map image from the external device, and proceeds to step S14.

  In step S14, the main CPU 108 sends an instruction to the display image creation circuit 110 to display a predetermined range of map images on the liquid crystal monitor 111 based on the map information, and the process proceeds to step S15. In step S15, the main CPU 108 determines whether or not an image file corresponding to the display range on the liquid crystal monitor 111 is recorded on the recording medium 10A. When the image photographed within the display range is present in the electronic camera 10, the main CPU 108 makes a positive determination in step S15 and proceeds to step S16, and the image photographed within the display range is not present in the electronic camera 10. In this case, a negative determination is made in step S15, and the process proceeds to step S20.

  In step S16, the main CPU 108 reads the additional information of the image file photographed within the display range from the recording medium 10A, and proceeds to step S17. In step 17, the main CPU 108 displays a mark at a corresponding position on the map image as illustrated in FIG. 2, and proceeds to step S18. The main CPU 108 also displays a pointer and a frame number display.

  In step S18, when the pointer is overlaid on the mark, the main CPU 108 reads a thumbnail image corresponding to the mark from the recording medium 10A, displays the read thumbnail image on the map image, and proceeds to step S19.

  In step S19, when the determination (OK) switch 113g is pressed while the thumbnail image is displayed, the main CPU 108 greatly increases the display size of the thumbnail image and causes the liquid crystal monitor 111 to display the expanded image on the full screen. The process proceeds to step S20.

  In step S20, the main CPU 108 determines whether or not a timeout has occurred. When the state in which no operation signal is input from the operation member 113 is continued for a predetermined time, the main CPU 108 makes an affirmative determination in step S20 and ends the process of FIG. On the other hand, when the operation signal is input or the state where the operation signal is not input is less than the predetermined time, the main CPU 108 makes a negative determination in step S20 and proceeds to step S21.

  In step S <b> 21, the main CPU 108 determines whether or not a mode change operation has been performed to the shooting mode. When the operation signal instructing the mode change is input from the mode changeover switch 113e, the main CPU 108 makes an affirmative determination in step S21 and ends the process of FIG. When the operation signal for instructing the mode change is not input from the mode switch 113e, the main CPU 108 makes a negative determination in step S21 and returns to step S11.

  In step S22, which proceeds after making a negative determination in step S11, the main CPU 108 performs a normal reproduction display process that does not display a map image, and then proceeds to step S20. In normal playback display, the image of the frame instructed by the pressing operation signal from the dial 113f is displayed over the entire display range of the liquid crystal monitor 111 (full screen display). For example, the right operation signal of the dial 113f corresponds to frame advance, and the left operation signal of the dial 113f corresponds to frame return. It is also possible to switch between the full screen display for displaying one frame image and the multiple frame display for displaying thumbnail images of a plurality of frames (for example, four frames) side by side.

  In step S23, which proceeds after making a negative determination in step S15, the main CPU 108 sends an instruction to the display image creation circuit 110 to overlay the following message on the map image. For example, the main CPU 108 displays a message “There is no image taken in this map range” on the liquid crystal monitor 111, and proceeds to step S20.

<Shooting mode processing>
Details of the shooting mode processing will be described with reference to the flowchart of FIG. The program according to FIG. 6 is stored in a memory (not shown) in the main CPU 108, and is activated when an operation for changing to the shooting mode is performed on the electronic camera 10. The operation for changing to the shooting mode is performed by the mode switch 113e.

  In step S51 of FIG. 6, the main CPU 108 starts energization of the blocks (the image sensor 101, the driver 104, etc.) constituting the imaging unit, and proceeds to step S52. In step S52, the main CPU 108 performs initial setting and positioning, and proceeds to step S53. The initial settings are settings for default shooting mode, display, image processing, and the like. In positioning, positioning information is acquired based on a received signal from the GPS device 114.

  In step S53, the main CPU 108 determines whether or not the release button 113a has been pressed halfway. When the half-press operation signal is input, the main CPU 108 makes a positive determination in step S53 and proceeds to step S54. When the half-press operation signal is not input, the main CPU 108 makes a negative determination in step S53 and proceeds to step S66.

  In step S54, the main CPU 108 sends an instruction to a focus detection device and a lens driving device 117 (not shown), detects the focus adjustment state by the lens L and performs focus adjustment, and proceeds to step S55. In step S55, the main CPU 108 starts imaging by the image sensor 101 (starts charge accumulation). The main CPU 108 ends the imaging when a predetermined time has elapsed, and sweeps the accumulated charges from the imaging element 101.

  In step S56, the main CPU 108 performs an exposure calculation using the image signal from the image sensor 101, and proceeds to step S57. In step S57, the main CPU 108 determines whether or not the release button 113a has been fully pressed. When the full-press operation signal is input, the main CPU 108 makes an affirmative determination in step S57 and proceeds to step S58. When the full-press operation signal is not input, the main CPU 108 makes a negative determination in step S57 and proceeds to step S66.

  In step S58, the main CPU 108 initializes the image sensor 101 (sweeps out unnecessary charges), and proceeds to step S59. In step S <b> 59, the main CPU 108 starts main imaging by the imaging device 101 (starts charge accumulation). The main CPU 108 drives and controls a shutter (not shown) and a diaphragm (not shown) based on the control exposure obtained in step S56, and when the control shutter time elapses, the main CPU 108 terminates imaging and accumulates from the image sensor 101. The charge is swept away.

  In step S60, the main CPU 108 sends an instruction to the image processing circuit 106, performs predetermined image processing on the image signal from the image sensor 101, and proceeds to step S61. In step S61, the main CPU 108 sends an instruction to the display image creation circuit 110 to create display data using the digital image signal after image processing, and the process proceeds to step S62. As a result, the captured image is reproduced and displayed on the liquid crystal monitor 111.

  In step S62, the main CPU 108 sends an instruction to the display image creation circuit 110, and overlays the following message on the captured image being reproduced and displayed. For example, the main CPU 108 displays a message “Do you want to edit the mark?” On the liquid crystal monitor 111 for a predetermined time, and proceeds to step S63.

  In step S63, when the main CPU 108 is instructed to edit the mark, the main CPU 108 makes an affirmative determination in step S63 and proceeds to step S64. For example, the main CPU 108 determines that a mark editing instruction has been issued when the determination (OK) switch 113g is pressed while the message is displayed, and if the determination (OK) switch 113g is not pressed, the mark editing instruction is not issued. judge.

  In step S64, the main CPU 108 performs mark selection processing. Specifically, an instruction is sent to the display image creation circuit 110 to display a mark list in which a plurality of marks registered in advance are superimposed on the captured image. The main CPU 108 moves the selected position in the mark list smoothly in the vertical direction in accordance with the pressed position signal from the dial 113f. For example, when the lower side of the dial 113f is pressed, the selected position is moved downward. When the upper side of the dial 113f is pressed, the selected position is moved upward. If the determination switch 113g is pressed, the mark selected at that time is selected and determined, and the process proceeds to step S65. When the process proceeds to step S65, the mark list display is ended.

  In step S65, the main CPU 108 records the image file in the buffer memory 109 on the recording medium 10A, and proceeds to step S66. In the image file, additional information including positioning information and mark information is stored together with image data. It should be noted that a normal round mark is automatically determined by the main CPU 108 as the mark when the negative determination is made in step S63.

  In step S66, the main CPU determines whether or not a timeout has occurred. When the state where the half-press operation signal is not input is continued for a predetermined time, the main CPU 108 makes an affirmative determination in step S66, performs an energization-off process for the blocks constituting the imaging unit, and ends the process of FIG. On the other hand, when the half-press operation signal is input or when the state where the half-press operation signal is not input is less than the predetermined time, the main CPU 108 makes a negative determination in step S66 and proceeds to step S67.

  In step S67, the main CPU 108 determines whether or not a mode change operation has been performed. When the operation signal for instructing the mode change is input from the mode changeover switch 113e, the main CPU 108 makes an affirmative decision in step S67 and ends the process of FIG. When the operation signal instructing the mode change is not input from the mode switch 113e, the main CPU 108 makes a negative determination in step S67 and returns to step S53.

(Modification 1)
In the above description, the mark is displayed in a large size when the adjacent marks overlap each other. If the types of overlapping marks are different, only one of the marks may be displayed. In this case, a priority order is set between marks in advance, and a mark with a higher priority order is displayed when both marks cannot be displayed individually.

(Modification 2)
If an image file corresponding to the display range on the liquid crystal monitor 111 is recorded on the recording medium 10A, marks corresponding to all of the recorded images are displayed on the map. Instead, only marks that are permitted to be displayed in advance may be selectively displayed. For example, display permission such as displaying a restaurant mark can be set for each mark by menu setting. With the configuration of the modified example 2, it is possible to display only the mark that the user desires to display.

(Modification 3)
Alternatively, only marks that are prohibited from being displayed in advance may not be selectively displayed. For example, display prohibition such as not displaying a heart mark can be set for each mark by menu setting. By adopting the configuration of the modified example 3, it is possible to prevent only the mark that the user does not want to display from being displayed.

(Modification 4)
The display permission and display prohibition of the modification 2 or the modification 3 may be permitted or prohibited only during a predetermined period. For example, display control is performed so that a mark for which display permission for one month is set is displayed until one month elapses and is not displayed after one month elapses. The setting of the period for each mark is performed by menu setting together with the above display permission and display prohibition.

(Modification 5)
You may make it register favorite information separately from the kind of mark. In the mark information in this case, a flag indicating the presence / absence of favorite registration is stored in addition to the information indicating the mark selected in the mark selection process. Favorite registration can be set for each image file by menu setting. When the menu is set so that only the favorite registered mark is selectively displayed, the main CPU 108 selectively displays only the favorite registered mark on the map regardless of the type of the mark. With the configuration of the modified example 5, only what the user desires can be displayed.

(Modification 6)
The round mark automatically determined by the main CPU 108 when step S63 (FIG. 6) is negatively determined may have a different color for each day. As a result, even when the mark selection process is not performed, if the shooting date is different, the mark is displayed in a different manner, so that the user can easily display the mark.

(Modification 7)
Although an example of switching between the shooting mode and the playback mode by the operation signal from the mode switch 113e has been described, the shooting mode may be activated when the release button 113a is pressed halfway during the playback mode. In this case, the main CPU 108 ends the playback mode and activates the shooting mode when a half-press operation signal from the release button 113a is input. After completing the shooting mode process, the playback mode is activated. By adopting the configuration of the modification example 7, it is possible to quickly prepare for photographing even while a map image is being displayed.

(Modification 8)
When full-screen display is performed in step S19 (FIG. 5), a configuration may be adopted in which frame advance or frame return is performed on the image being displayed on the full screen in accordance with the pressed position signal from the dial 113f. For example, the right operation signal of the dial 113f corresponds to frame advance and the left operation signal corresponds to frame return. Further, when the zoom switch 113b is pressed while the full screen is displayed, the main CPU 108 displays a map image that displays a point at which the image currently displayed on the full screen is captured.

  Specifically, the main CPU 108 reads the additional information of the image file displayed on the entire screen, and acquires positioning information and mark information indicating the position where the image is taken. The main CPU 108 sends an instruction to the display image creation circuit 110 to display a map image of a predetermined range including the position (shooting position) indicated by the positioning information on the liquid crystal monitor 111, and then displays a mark indicating the shooting position. Make it. With the configuration of the modified example 8, after selecting a frame to be displayed on the full screen, the map image display of FIG. 2 including the shooting position of the image can be performed. Note that marks, pointers, and frame number indications indicating other shooting positions are displayed in the same manner as in FIG.

(Modification 9)
The electronic camera 10 displays a thumbnail image corresponding to the case where the pointer 31 overlaps any one of the marks 21 to 26 on the map image, and the determination (OK) switch 113g is pressed while the thumbnail image is displayed. And the thumbnail image is displayed in full screen on the liquid crystal monitor 111. Instead, the corresponding thumbnail image may be displayed on the full screen when the pointer 31 overlaps any one of the marks 21 to 26. The user can easily confirm the details of the thumbnail image.

(Modification 10)
The orientation of the map image displayed on the liquid crystal monitor 111 may be changed according to the detection information from the attitude sensor 115. The main CPU 108 sends an instruction to the display image creation circuit 110 to change the orientation of the map image displayed on the liquid crystal monitor 111 in accordance with the attitude (horizontal position or vertical position) of the electronic camera 10. With the configuration of the modification 9, the map image can be displayed in a direction that is easy for the user to see regardless of the orientation of the electronic camera 10.

(Modification 11)
Although the electronic camera 10 has been described as an example of the electronic device, a mobile phone with a camera or a PDA with a camera may be used.

  The above description is merely an example, and is not limited to the configuration of the above embodiment. The embodiment used in the description and the first to eleventh modifications may be combined as appropriate.
