  Hereinafter, an image processing apparatus according to an embodiment of the present invention will be described with reference to the drawings, taking a camera as an example. FIG. 1 is a block diagram illustrating a system configuration of a camera according to an embodiment. The camera 2 includes a CPU 4. The CPU 4 includes a motor control unit 8 that drives a photographic lens provided in the lens barrel unit 6, images a subject through the photographic lens, and an imaging signal (analog signal as accumulated charge). An image storage 12 that stores image data generated by A / D conversion of an image pickup signal output from the image pickup element 12 in an A / D conversion unit (not shown). 14, an image processing unit 16 that performs image processing such as white balance adjustment, contour compensation, and gamma correction on image data stored in the image storage unit 14, a memory card 18 that stores an image subjected to image processing, Communicating with external devices such as mobile phones with a GPS function and car navigation systems via Bluetooth, Wifi, Transferjet, etc. Radio unit 20 to be acquired, acquisition interval setting unit 22 for setting an interval for acquiring position information, map data, browser for displaying map data, geography for storing position information and trajectory information on which the position information has moved over time An information storage memory 24, a display control unit 28 that performs display control of a display unit 26 configured by an LCD, an operation unit 30 that includes a release button that performs a release instruction, a RAM 32 that is a work memory of the CPU 4, and a basic operation of the camera A firmware storage memory 34 for storing firmware, a USB interface 36 to which a USB device is connected, an audio processing unit 40 for A / D converting audio input from a microphone 38, and audio control for controlling output of audio output from a speaker 42 The part 44 is connected. Further, the display unit 26 is provided with a stack of touch sensors 29 made of transparent electrodes, and can accept user operations.

  Next, imaging processing of the camera according to the embodiment will be described with reference to the flowchart shown in FIG. First, the position information acquisition interval is set (step S1). That is, the acquisition interval of position information input by the user using the touch sensor 29 is set in the acquisition interval setting unit 22. When the setting of the acquisition interval is completed, position information is acquired from an external device having a GPS function such as a mobile phone or a car navigation system via the wireless unit 20, and stored in the geographic information storage memory 24 (step S2). Then, it is determined whether or not a release instruction has been made by operating the release button before a time corresponding to the acquisition interval (hereinafter referred to as acquisition interval time) elapses (step S3). If the release instruction is not issued within the acquisition interval time, the position information is acquired again from the external device when the acquisition interval time has elapsed and stored in the geographic information storage memory 24 (step S2).

  On the other hand, if a release instruction is issued within the acquisition interval time, the subject is imaged by the image sensor 12 (step S4), and the image data is stored in the memory card 18. That is, the image data is stored in the memory card 18 in the Exif file format, and the position information corresponding to the imaging point, the time when the imaging was performed, and the like are stored as header information (step S5). Then, it is confirmed whether or not to end the imaging (step S6). Here, when an instruction to end imaging is input via the touch sensor 29 or the operation unit 30, imaging is terminated, and the image data stored in the memory card 18 is classified based on the position information, and for each position information. Store in a different folder (step S7). Then, the folder created for each position information stored in the memory card 18 is stored in a travel folder that stores all image data in one trip, and the position stored in the geographic information storage memory 24 is stored. Trajectory information for this trip is created from the information and stored in correspondence with this travel folder.

  On the other hand, if an imaging end instruction is not input in step S6, the process returns to step S3 and the imaging process is continued.

  Next, the travel reproduction process of the camera according to the embodiment will be described with reference to the flowchart shown in FIG. In the travel reproduction according to the present embodiment, the image data stored in the travel folder instructed to be reproduced and the map are displayed. In addition, it is selected whether or not to display images stored in the travel folder in the slide show display before the travel reproduction. For example, a browser for displaying a map is started, a trajectory based on trajectory information stored in association with a travel folder is displayed on the map, and a position on the trajectory associated with each folder in the travel folder An instruction image such as a flag is displayed on the screen. When the user designates 1 flag using the touch sensor 29, the images stored in the folder associated with the position indicated by the flag are displayed as thumbnails, and a slide show is displayed from the thumbnail displayed images. An image to be displayed is selected using the touch sensor 29. At this time, the display range of the map displayed on the display unit 26 may include the entire trajectory or may include only a part of the trajectory. When only a part of the trajectory is displayed, the display range is changed by scrolling using the touch sensor 29, and a selection is made as to whether or not to display all images associated with the position information of the entire trajectory in the slide show display. Do. When the user designates a flag of 1, a slide show of images stored in a folder associated with the position information of the flag position is displayed, and images displayed in the slide show display during travel reproduction are displayed by a touch sensor. 29 may be used for selection.

  When the travel reproduction process is performed, the user selects the travel reproduction mode and the travel folder for reproduction from the menu screen displayed on the display unit 26. Thereby, the browser for displaying a map starts (step S11). Then, the trajectory information stored in association with the selected travel folder is read (step S12), and the other person image associated with the position information included in the trajectory information is displayed on the web or the like via the wireless unit 20. (Step S13). If another person's image exists, position information associated with the image data is acquired via the wireless unit 20 (step S14). For example, as the position information of the other person image, the position information associated with the image taken by the other person who traveled together is acquired. Further, position information associated with an image provided from a transportation organization such as an airline or a railway company, a travel company, or the like may be acquired as the position information of the other person image.

  Next, it is determined whether the acquisition interval of the position information constituting the trajectory information associated with the travel folder to be reproduced in the travel reproduction mode is coarse or fine, that is, whether it is long or short (step S15).

  For example, when the acquisition interval is set to 10 seconds or more, it is determined that the acquisition interval is long (coarse) (step S15: No), and all the trajectories based on the trajectory information are included on the map displayed on the display unit 26. The display range of the map is adjusted and displayed as shown (step S16). At this time, an instruction image such as a flag as an imaging point is displayed on the map at a position based on the locus information and the position information associated with each folder included in the travel folder. In addition, an instruction image such as a flag is also displayed at an imaging point where another person's image exists. In this case, the flag color is changed and displayed. Then, a moving image of the cursor or the like is displayed on the locus, and the movement of the cursor is started at a predetermined speed set in advance from the starting point that is the initial point on the locus (step S17).

  When the cursor moves to the vicinity of the flag, the slide show is displayed using the images selected to be displayed in the slide show display among the images stored in the folder associated with the position information indicated by the flag. (Step S18). The slide show display may be performed when at least a part of the cursor and the flag overlap each other, or may be performed when the cursor is positioned around the flag. When the image to be displayed as a slide show is an image of another person, the touch sensor 29 selects whether or not to download the image data of the other person image from the web or the like, and the image of the other person is displayed only when the image is downloaded. Is displayed as a slide show. Here, when the cursor moving speed is set fast, the switching time of the image displayed on the display unit 26 in the slide show display is shortened compared to the case where the cursor moving speed is set slow, The image switching time may be linked.

  When the slide show display ends, it is determined whether or not there is a next imaging point in the moving direction on the locus (step S19). If there is a next imaging point, the process returns to step S17 to continue the travel reproduction process. On the other hand, if the next imaging point does not exist, the process ends.

  If the acquisition interval is set to, for example, less than 10 seconds in step S15, it is determined that the acquisition interval is short (fine) (step S15: Yes) and is based on the trajectory information on the map displayed on the display unit 26. The display range of the map is adjusted and displayed so that the starting point of the locus and the first imaging point in the moving direction of the cursor are included (step S20). Then, the cursor starts to move at a predetermined speed displayed on the locus from the starting point (step S21).

  Since the processes shown in steps S22 and S23 are the same as the processes shown in steps S18 and S19, respectively, the description thereof is omitted. In step S23, when the next imaging point exists, the display range of the map displayed on the display unit 26 is changed (step S24). That is, the display range of the map is moved and displayed so that a trajectory including the imaging point that has been displayed as a slide show immediately before and the next imaging point is displayed. Then, returning to step S21, the cursor is moved from the imaging point where the slide show was displayed immediately before to the next imaging point, and the travel reproduction process is continued. On the other hand, if the next imaging point does not exist in step S23, the process ends.
