A. Configuration of Embodiment FIG. 1 is a block diagram showing a configuration of a digital camera according to an embodiment of the present invention. In the figure, the image acquisition unit 10 includes a lens 11, a shutter 12, and an LPF 13. The lens 11 is a normal optical lens and includes a lens group in which aspherical lenses are stacked. The shutter 12 is a so-called mechanical shutter that is operated by a driver 14 driven by the control unit 20 when the shutter button 7 is operated. Depending on the digital camera, a mechanical shutter may not be provided, and in the case of a model equipped with a retractable lens structure and mechanical zoom, these drivers are also controlled by the driver 14. The LPF 13 is a crystal low-pass filter and is mounted to prevent the occurrence of moire.

  Next, the analog signal processing unit 15 includes an image sensor (CCD, CMOS) 16, a sampling / signal amplification processing unit 17, and an A / D converter 18. The imaging sensor 16 forms a subject image (image), and converts the intensity of light of each color of RGB into a current value. The sampling / signal amplification processing unit 17 performs correlated double sampling processing and signal amplification processing for suppressing noise and color unevenness. The A / D converter 18 is also called an analog front end, and converts the sampled / amplified analog signal into a digital signal (converts each color of RGB and CMYG into 12-bit data and outputs it to the bus line).

  Next, the control unit (CPU) 20 controls the entire digital camera (imaging device) based on a program stored in a program memory described later. In particular, in the present embodiment, the control unit (CPU) 20 multiplexes audio data and video data during moving image shooting, generates a moving image file, and becomes a condition for selecting a frame of the moving image, which will be described later. When an event corresponding to the recording factor designated by the key operating unit 27 occurs, the information indicating the recording factor in association with the frame number at that time, or the position information input unit 34 described later is acquired. Position information and the like are sequentially recorded in the selected frame file. Details of the recording factor and the selected frame file will be described later.

  In addition, when a search factor (= recording factor) for searching for a desired frame image is designated from the key operation unit 27 after moving image shooting, the control unit (CPU) 20 selects a moving image file after shooting and selection. Using the frame file, a frame image corresponding to the search factor and its position information are searched and extracted from the moving image file, and a predetermined process (for example, slide show display or movie print) is performed.

  The timer unit 21 measures the elapsed time from the start of moving image capturing. The preview engine 22 is stored in the image buffer 26 immediately after detection of digital data input via the image acquisition unit 10 and the analog signal processing unit 15 in the recording mode (also referred to as recording mode or photographing mode) or shutter operation detection. Thinning processing is performed in order to display the digital data and the digital data stored in the image memory 31 on the display unit 25.

  The D / A converter 23 converts the digital data thinned out by the preview engine 22 and outputs it to the driver 24 at the subsequent stage. The driver 24 includes a buffer area for temporarily storing digital data displayed on the display unit 25 at the subsequent stage, and drives the display unit 25 based on a control signal input via the key operation unit 27 and the control unit 20. The display unit 25 includes a color TFT liquid crystal, an STN liquid crystal, or the like, and displays a preview image, image data after shooting, a setting menu, and the like.

  The image buffer 26 temporarily stores digital data immediately after photographing until it is input via the analog signal processing unit 15 or the digital signal processing unit 28 and passed to the digital signal processing unit 28. The key operation unit 27 inputs various operation keys such as a recording / playback mode switching key, a cross key, a menu key, and the like, a recording factor as a condition for recording position information, and the like including the shutter button 7.

In addition, various information to be embedded in a file compliant with the DCF standard is also stored. The image memory 31 stores digital data converted into various file formats. The card I / F 32 controls data exchange between the external recording medium 33 and the imaging apparatus main body. The external recording medium 33 includes a compact flash (registered trademark), a memory stick, an SD card, and the like.

  The position information input unit 34 includes a GPS or the like, and acquires position information (latitude and longitude) indicating the current position at a predetermined time interval. The microphone 36 inputs sound when shooting a moving image. The speaker 37 outputs sound when playing back a moving image. The audio processing unit 38 performs encoding (compression) / decoding (decompression) or the like using a predetermined codec, thereby converting the audio data output to the speaker 37 into an analog signal and digitizing the audio signal from the microphone 36. .

  FIG. 2 is a conceptual diagram showing the configuration of the selected frame file created in this embodiment. In the present embodiment, the position information and the like are stored as a selected frame file different from the moving image file when the moving image is in a state that matches a pre-specified recording factor together with the captured moving image. As shown in FIG. 2, the selected frame file includes the number of selected frames indicating the number of recorded frames, the frame number of the frame where the position information is recorded, the recording factor indicating the factor that recorded the frame, and the frame recorded. It is composed of coordinates indicating the recorded position and an azimuth indicating the traveling direction when the frame is recorded. As recording factors, there are time passage, distance change, direction change, designated direction, and a combination thereof.

  In the illustrated example, since the number of selected frames is “5”, it can be seen that a total of 5 frames are recorded. As the recorded frames, frame numbers “1”, “2345”, “6789”, “12345”, and “23456” are recorded. In addition, the recording factor of each frame is that the frame number “1” is the leading frame, the frame number “2345” is the position change, the frame number “6789” is the direction change, and the direction is the direction in which the frame number “12345” is specified. Change, frame number “23456” is a position change or direction change. A recording factor is generated for each frame, and coordinates indicating a position when the frame is recorded and an azimuth indicating a traveling direction at that time are recorded.

  FIGS. 3A to 3C are schematic views showing an example of a position data recording factor setting screen for designating a frame for recording position information in the present embodiment. As shown in FIGS. 3A to 3C, the position data recording factor setting screen displays time, distance change, direction change, and designated direction as designation items for designating a frame for recording position information. For each, a check box for instructing validity / invalidity and an input box for inputting a specific numerical value are displayed. On the position data recording factor setting screen, the user may check a check box of a desired item and input a specific numerical value in order to designate a frame for which position information is to be recorded.

  FIG. 3A shows a state in which the position information is specified to be recorded together with the recording factor information every time the distance changes by 50 m or more and every time the traveling direction changes by 30 ° or more. FIG. 3B shows a state in which the position information is specified to be recorded together with the recording factor information at the moment when the traveling direction changes from north to northeast. Further, in FIG. 3C, while the traveling direction is between the north-northeast and the north-east, every time 20 seconds elapses, it is designated that the position information is recorded together with the recording factor information. It is shown.

  As described above, in the present embodiment, by specifying various conditions, the condition information is recorded when the conditions are met, and further, by combining these conditions in detail and concretely. It is possible to specify. For this reason, after shooting, it is possible to extract a desired frame by specifying various conditions or combining those conditions as in shooting, and it can be used for various uses. It becomes like this.

  Next, FIG. 4 is a conceptual diagram showing recording factors that are automatically set by designating an application to be used after shooting in the present embodiment. In this embodiment, it is possible to extract and use a frame that meets a desired condition from a moving image after shooting by referring to the above-described selected frame file (FIG. 2) from various applications after shooting. . Therefore, in this embodiment, by specifying an application to be used after shooting before shooting, an appropriate recording factor for the application is automatically set.

  Examples of applications used after shooting include a slide show, movie print, and navigation. In the slide show, time passage and distance change (AND condition) are automatically set as recording factors. In movie print, a change in distance is automatically set as a recording factor. In navigation, a change in direction is automatically set as a recording factor. The combinations of these applications and recording factors are set in advance as defaults, but can be arbitrarily reset by a user operation.

  FIG. 5 is a schematic diagram showing an application setting screen when setting an application assumed to be used after shooting in the present embodiment. In the present embodiment, as described above, by specifying an application to be used after shooting, a recording factor appropriate for the application is automatically set. Therefore, in the present embodiment, as shown in FIG. 5, an application setting screen for specifying an application to be used is prepared.

  On the application setting screen, a list of available applications and a check box for specifying each are displayed. On the application setting screen, the user may check a check box of a desired application in order to specify an application to be used. By specifying an application, the recording factors shown in FIG. 4 are automatically set, and when shooting a moving image, if the set recording factors are satisfied, position information or the like is recorded in association with the frame at that time. It has become.

B. Operation of Embodiment Next, the operation of the above-described embodiment will be described.
6 and 7 are flowcharts for explaining the operation of the digital camera according to the present embodiment. In the illustrated flowchart, the loop of steps S10 to S40 is executed in synchronization with the frame rate at the time of moving image shooting, and is executed for each frame at the time of moving image shooting. For example, if the frame rate at the time of moving image shooting is 30 fps, the loop of steps S10 to S40 is executed every 1/30 seconds. Further, it is assumed that the recording factors are set in advance on the position data recording factor setting screen shown in FIGS. 3A to 3C and the application setting screen shown in FIG.

  First, the current position information is acquired (step S10), and the moving distance and the moving direction are calculated by comparison with the position information of one frame before stored in the step described later (step S12). Note that the moving distance and moving direction are cumulative values from the start of shooting, and are cleared when the conditions of the recording factor are met in the steps described later. Next, the current position information is temporarily held in a predetermined register or the like (step S14). The position information is used as position information one frame before in step S12. Next, the recording factor (register) is set to “none (clear)” (step S16).

  Next, it is determined whether the passage of time is designated as a recording factor and whether the passage of time from the start of photographing has reached the designated passage of time (step S18), and if the recording factor is satisfied. Then, “time elapsed” is recorded as the recording factor of the selected frame file (step S20).

  Further, it is determined whether a change in distance (movement distance) is designated as a recording factor, and whether the distance has changed more than the designated value (step S22). If the recording factor is satisfied, the selected frame file is determined. The “position change” is recorded as the recording factor (step S24).

  Further, it is determined whether or not the direction change is designated as a recording factor and whether or not the direction has changed more than the designated value (step S26). If the recording factor is satisfied, the recording factor of the selected frame file is determined. , “Direction change” is recorded (step S28).

  Further, it is determined whether or not the direction is designated as the recording factor and the moving direction has changed to the designated direction (step S26). If the recording factor is satisfied, the recording factor of the selected frame file is determined. "Direction change" is recorded (step S28).

  Next, it is determined whether or not the recording factor is satisfied (step S34). If any of the recording factors is satisfied in the above-described steps S18 to S32, the current position information is selected as the selected frame file. The moving direction is recorded at the coordinates of the direction (step S36), and the serial number and frame number assigned to the frame recorded in the selected frame file are recorded (step S38). On the other hand, if one recording factor is not satisfied in the above-described steps S18 to S32, the coordinates, direction, serial number, and frame number are not recorded. Of course, in this case, no recording factor is recorded.

  Next, it is determined whether or not the moving image shooting is continued (step S40). If the moving image shooting is continued, the process returns to step S10 and the above-described processing is repeated for the next frame. On the other hand, when the moving image shooting is finished, the number of selected frames (position information number) is recorded in the selected frame file, and the process is finished (step S42).

  According to the embodiment described above, a moving image file and a selected frame file as shown in FIG. 2 are generated after moving image shooting. That is, each time a state that satisfies a pre-specified recording factor occurs, the frame number at that time, the recording factor indicating what was recorded, the coordinates (position information) at that time, and the direction (traveling direction) ) Is generated. Therefore, after shooting a movie, it is possible to obtain a frame number that matches the search condition by searching the selected frame file using the recording factor, coordinates, and orientation as keys, and by specifying the frame number, Frames (still images) that match the search conditions can be easily extracted from the file.

Next, use after moving image shooting will be described.
First, as a use after movie shooting, by specifying a search factor and a search start frame number after movie shooting and searching a selected frame file, a frame number that matches the specified search factor and its position information (coordinates) ), A frame (still image) of the extracted frame number is extracted from the moving image file, and a predetermined process is executed based on position information recorded in association with the frame.

As a process using position information, for example, there is the following usage.
(1) Display (paste) a frame (still image) on a map based on the position information.
(2) Print as a frame (still image) at a different place or at a position change point based on the position information.
(3) Display while jumping to the frame of the position change point based on the position information (use as an index).
(4) Display while jumping to a frame at a position more than a specified distance based on the position information.
(5) Based on the position information, display while jumping to the frame at the position in the designated direction.
(6) Based on the position information, the moving image is played in specified seconds from the position change point (use as a slide show).

  FIG. 8 is a diagram for explaining the operation of a search process for extracting a frame (still image) that matches a specified search factor from a moving image file and executing a predetermined process based on position information for the frame in the present embodiment. It is a flowchart of. First, a search factor (= recording factor) is designated (step S50). The search factors correspond to any of the above-mentioned recording factors or combinations, for example, a frame with “position change”, a frame with “direction change”, and a frame with “direction change in specified direction”. A frame having a “position change” or “direction change” is assumed.

  Next, the search start frame number is designated, and the search is started (step S52). When the search is started, first, as an initial setting, the counter is set to “0”, the result (register) is set to “no match”, and the position information (register) is set to “0” (step S54). The counter counts the frames to be searched and corresponds to the serial number assigned to the frame number recorded in the selected frame file.

  Next, it is determined whether or not the counter is equal to or greater than the number of selected frames (number of position information) in the selected frame file, that is, whether or not the search has been completed for all the frames in the selected frame file (step S56). If the search is not completed for all the frames, the position information of the position pointed to by the counter is read (step S58). Next, it is determined whether or not there is a search factor in the recording factor at the position indicated by the counter (step S60). If there is no search factor in the recording factor, the frame is not applicable, so the counter is set to “1”. Increment (step S62), return to step S56, and repeat the above-described processing for the next recorded frame.

  On the other hand, if there is a search factor in the recording factor of the position pointed to by the counter in step S60, the frame number of the position is stored in the result (register), and the coordinates of the position are stored in the position information (register) ( Step S64). Next, it is determined whether or not the frame number stored in the result (register) is less than the specified search start frame number (step S66). If it is less than the search start frame number, the counter is set in step S62. Increment by "1", return to step S56, and repeat the above-described processing for the next recorded frame.

  On the other hand, if the frame number is not less than the designated search start frame number in step S66, the frame (still image) of the frame number stored in the result (register) is extracted from the moving image file, and the frame (still image) is extracted. Image) and the coordinates stored in the position information (register), a predetermined process is executed (step S68). Next, it is determined whether or not the next frame is to be searched (step S70). If the next frame is to be searched, the counter is incremented by “1” in step S62, and the process returns to step S56. The above-described processing is repeated for the recorded frame.

  On the other hand, if the counter is equal to or greater than the number of selected frames in step S56, or if it is selected not to search for the next frame in step S70, the process ends. In the above-described processing, the predetermined processing is not executed for each extracted frame (still image), but all frame numbers and position information corresponding to the search factor are held, After the search process is completed, the predetermined process may be performed while sequentially extracting the corresponding frame (still image) from the moving image file in accordance with all the stored frame numbers and position information.

  Next, as a use after moving image shooting, a case where a frame in which position information is recorded after a moving image is played back as a slide show will be described.

  FIG. 9 is a flowchart for explaining the operation of a slide show reproduction process for extracting a frame in which position information is recorded from a moving image file and reproducing the slide show after moving image shooting according to the present embodiment. First, it is determined whether or not the number of selected frames in the selected frame file is greater than “10” (step S80). This is because when the number of frames in which position information is recorded is 10 or less, the effect of slide show reproduction cannot be expected so much. Therefore, when the number of selected frames in the selected frame file is “10” or less, the processing ends.

  On the other hand, if the number of selected frames in the selected frame file is greater than “10”, the counter is set to “0” (step S82), the frame number at the position pointed to by the counter is obtained (step S84), and from the moving image file. A frame (still image) with the frame number is acquired (step S86).

  Next, the acquired frame (still image) is set in advance, or is reproduced and displayed for a predetermined time designated by the user (step S88), and the counter is incremented by “1”, and the counter exceeds the number of selected frames. It is determined whether or not the number of selected frames is greater than or equal to the number of selected frames (step S92), the process returns to step S84 and the above-described processing is repeated for the next frame. Then, when the reproduction of the frames corresponding to all the frame numbers recorded in the selected frame file is finished, the processing is finished.

  Next, as a use after moving image shooting, a case of printing a frame in which position information is recorded after moving image shooting will be described.

  FIG. 10 illustrates an operation of a movie print process according to the present embodiment, in which a frame in which position information is recorded is extracted from a moving image file after moving image shooting, and is arranged and printed at a position in a page corresponding to the position information. It is a flowchart for. First, it is determined whether or not the number of selected frames in the selected frame file is greater than “10” (step S100). This is because when the number of frames in which the position information is recorded is 10 or less, the effect cannot be expected so much even if the print is arranged in the page according to the position information. Therefore, when the number of selected frames in the selected frame file is “10” or less, the processing ends.

  On the other hand, if the number of selected frames in the selected frame file is greater than “10”, the counter is set to “0” (step S102), the frame number at the position pointed to by the counter is acquired (step S104), and from the moving image file. A frame image (still image) with the frame number is acquired (step S106).

  Next, the acquired frame image (still image) is arranged and synthesized at a position in the page corresponding to the coordinates (position information) (step S108), and the counter is incremented by “1” (step S110). It is determined whether or not the counter is equal to or greater than the number of selected frames (step S112). If it is not equal to or greater than the number of selected frames, the process returns to step S104 and the above-described processing is repeated for the next frame. When the frame images corresponding to all the frame numbers recorded in the selected frame file have been combined into the page, the combined frame image arranged in the page is printed (step S114), and the process ends. To do.

  According to the embodiment described above, since the position information is recorded when the designated recording factor occurs, the processing efficiency and the recording efficiency can be improved. In addition, since the corresponding frame and position information can be searched based on the designated recording factor, the frame at the change point of the position information can be easily extracted, and the convenience in use after moving image shooting is improved. be able to.

  In the embodiment described above, the position information may be recorded in association with the frame number at that time by key operation during moving image shooting. Further, altitude or altitude change may be added as a recording factor, and position information may be recorded in association with the frame number at that time at a specified altitude or at a specified altitude change. Alternatively, the position information may be searched in the reverse order of the frame number.
