  Next, with reference to FIG. 2 and FIG. 3, a method for reproducing a moving image in the present embodiment will be described. FIG. 2 shows a state where the user 20 reproduces the image of the moving image 31 recorded on the camera 10 while moving the camera 10 in the horizontal direction. The moving image 31 is taken between time 0 and time T0, and is a virtual display in FIG.

  As described above, the X-axis direction is the longitudinal direction (horizontal direction) of the camera 10, and the front of the user 20 is 0 on the X-axis, the left end of the moving range is −X0, and the right end of the moving range is + X0. To do. When the user 20 moves the camera 10 horizontally in the X-axis direction from −X0 to + X0, the frame of the moving image 31 is displayed on the display element 314 in accordance with the movement of the camera 10. That is, the position of the camera 10 is obtained by integrating the outputs of the angular velocity detection circuit 230 and the acceleration detection circuit 250 in the camera 10 with the reproduction start of the moving image 31 corresponding to the position (−X0) and the reproduction end corresponding to the position (+ X0). And the frame of the moving image 31 corresponding to the detected position is displayed on the display element 314.

  Since the angular velocity around the Y axis is detected by the angular velocity detection circuit 230, the rotational angle around the Y axis is obtained by integrating the angular velocity, and the amount of movement along the X axis direction is calculated therefrom. Further, since the acceleration detection circuit 250 detects the acceleration in the X-axis direction, the movement amount in the X-axis direction may be calculated by integrating the acceleration.

  FIG. 3A shows a case where a plurality of moving image representative images (four in the illustrated example) are displayed on the display element 314 of the camera 10. When the user touches the moving image to be reproduced, the moving image touched by the user is specified based on the touch signal from the touch panel 324, and the representative image of the moving image is enlarged and displayed as shown in FIG. When the camera 10 is moved to the left (in the direction of (−X0) in FIG. 2) in the enlarged display state, the previous image for the time corresponding to the amount of movement is displayed as shown in FIG. On the other hand, when the camera 10 is moved to the right (in the direction of + X0 in FIG. 2), an image after a time corresponding to the amount of movement is displayed as shown in FIG. When the user views a frame and operates an operation button such as a playback button, playback of the moving image is started.

  Next, the operation of camera control in the present embodiment will be described using the flowchart shown in FIG. This flowchart is executed by the CPU 110 based on a program stored in the flash memory 340.

  When the camera control operation is started, it is first determined whether or not the camera is in shooting mode (S1). Here, it is determined by the mode dial of the operation switch 380 whether or not the shooting mode has been set. If the result of this determination is that the shooting mode has been set, then imaging and display are performed (S3). Here, live view display is performed on the display element 314 based on the image signal acquired by the imaging element 214.

  Once imaging and display have been performed, it is next determined whether or not to start imaging (S5). Here, it is determined whether or not the release button of the operation switch 380 has been operated. In the present embodiment, when the moving image shooting mode is set, moving image shooting starts when the release button is operated, and moving image shooting ends when the release button is operated again. Of course, a dedicated moving image button may be provided to instruct the start and end of moving image shooting.

  If the result of determination in step S5 is that shooting has not started, processing returns to step S1. On the other hand, if the result of determination is that shooting has started, the count of the timer counter 132 is reset to 0 (S7). Subsequently, moving image shooting is started (S9). Here, the image signal of the moving image acquired by the image sensor 214 is processed and temporarily stored in the SDRAM 350. Also, the timer is counted (S11). Here, a timer operation is performed by the timer counter 132.

  Next, it is determined whether or not the photographing is finished (S13). As described above, when the release button is operated again, the moving image shooting is ended. If the result of this determination is that shooting has not ended, processing returns to step S9 and video shooting continues. On the other hand, if the result of determination is that photographing has been completed, the time T counted by the timer counter 132 is set to T1 (S15), and the time measured T and each image are recorded in association with each other (S17). Here, as described in FIG. 2, the shooting start time T = 0 and the shooting end time T = T1 are associated with each other so as to correspond to the image at the start of shooting of the moving image 31 and the image at the end of shooting. The elapsed time is associated with each image of the moving image shot between T = 0 and time T = T1. When the association between each image and the timer count T is completed, moving image data is recorded in the memory card 334. When the recording ends, the process returns to step S1.

  If the result of determination in step S <b> 1 is not shooting mode, playback mode is executed. First, a list of photographed image files is displayed (S21). Here, representative images are read from the moving images recorded on the memory card 334 and displayed as a list on the display element 314. As a way of displaying the list, for example, thumbnails are displayed as shown in FIG. Subsequently, it is determined whether or not to return (S22). Since a list display is displayed and a “return” icon is displayed, it is determined in this step whether or not the “return” icon has been touched. If the result of this determination is “return”, the process returns to step S1.

  If the result of determination in step S22 is not "return", it is next determined whether or not it has been selected (S23). Here, for example, as described with reference to FIG. 3, the determination is made based on whether or not the user touches the display element 314 in order to select a moving image. If the result of this determination is that it has not been selected, processing returns to step S22.

  If any of the photographed image files is selected as a result of the determination in step S23, the representative image is then enlarged (S25). Here, the representative image of the selected moving image is enlarged and displayed on the display element 314 as shown in FIG. Subsequently, it is determined whether or not to return (S26). Since the representative image is displayed and the “return” icon is displayed, it is determined in this step whether or not the “return” icon has been touched. If the result of this determination is “return”, the process returns to step S1. On the other hand, if the result of determination is not “return”, it is determined whether or not to start playback (S27). Here, it is determined whether or not the user has given an instruction to start playback by operating the video playback button or the like.

  If the result of determination in step S27 is that reproduction has started, it is next determined whether or not a representative image is being displayed (S29). Since the representative image remains displayed before reproduction is started, it is determined in this step whether or not the representative image remains displayed. If the result of this determination is that a representative image is being displayed, next top frame display is performed (S31). Here, the first frame image is read from the moving image file stored in the memory card 334 and displayed.

  If the top frame is displayed in step S31, or if the result of determination in step S29 is that the representative image is not being displayed, moving image playback is performed from the playback frame (S33). That is, when the top frame is displayed in step S31, the moving image playback is started from the top frame, and when the representative image is not displayed as a result of the determination in step S29, the playback frame of the moving image being played is started. Continue playing the video.

  If the operation reproduction is performed in step S33, it is next determined whether or not the reproduction is finished (S35). Here, it is determined whether or not an end of reproduction has been instructed by an operation of a moving image reproduction button or the like. That is, in this embodiment, when an operation for instructing to end reproduction is performed again using a moving image reproduction button or the like, the reproduction ends. If the result of this determination is that playback has not ended, processing returns to step S29 and video playback continues. On the other hand, if the reproduction has ended, the reproduction ends and the process returns to step S25.

  If the result of determination in step S27 is that playback has not started, that is, if video playback is not performed, it is determined whether or not movement amount playback start is to be performed (S40). If the user moves the camera 10 without starting normal video playback, it may be desired to prohibit the display of video frames corresponding to the amount of movement. Therefore, in the present embodiment, a movement amount reproduction mode that permits frame display of a moving image in accordance with the amount of movement is set by operating a menu screen or a dedicated operation member. In step S40, it is determined whether or not the movement amount reproduction mode is set. As a result of the determination, if the movement amount reproduction mode is not set, the process returns to step S26.

  If the movement amount reproduction mode is set as a result of the determination in step S40, detection of the movement amount is started, and it is determined whether there is a movement in the X direction and no movement in the Y direction (S41). That is, here, the user moves the camera 10 in the horizontal direction, but at this time, it is determined whether or not the camera 10 is moved in the vertical direction. As described with reference to FIG. 2, in the present embodiment, when the user moves the camera 10 in the horizontal direction, a moving image frame corresponding to the position in the horizontal direction is reproduced.

  If the result of determination in step S41 is that there is movement in the X direction and there is no movement in the Y direction, the amount of movement at that time is determined to be X (S43). Here, based on the detection outputs of the angular velocity detection circuit 230 and the acceleration detection circuit 250, the amount of motion from X = 0 is obtained as X.

  Once the amount of motion is determined, next, a frame with a timing of (X − (− X0)) × T1 / 2X0 is displayed (S45). As described above, the movement range of the camera 10 is the range from (−X0) to (X0), and this range corresponds to the reproduction time T1 of the moving image. Find and display video frames according to. For this reason, when the camera is moved left and right along the horizontal direction, frames corresponding to the amount of movement are sequentially displayed on the display element 314. This display is like frame advance / return, fast forward / return, and any frame can be easily displayed. At this stage, only the frame of the moving image designated according to the amount of movement is displayed, and the moving image reproduction is not started.

  When the moving picture frame is displayed, it is next determined whether or not to return (S47). On the display element 314, the frame of the designated moving image is displayed and a “return” icon is displayed. In this step, it is determined whether or not the “return” icon is touched. If the result of this determination is that the “return” icon is not touched, processing returns to step S41. For this reason, the frame of the designated moving image changes according to the movement of the camera 10.

  On the other hand, if the “return” icon is touched as a result of the determination in step S47, the process proceeds to step S27. When the reproduction is started, the moving image reproduction is started from the designated moving image frame in step S33. In the present embodiment, the “return” icon is displayed on the display element 314. However, the present invention is not limited to this, and for example, a return operation member may be provided.

  Thus, in the present embodiment, when there is a movement in the X direction and no movement in the Y direction, that is, there is no inclination in the direction orthogonal to the display surface of the display element 314, and the position changes in the orthogonal direction. When the camera moves in a state where there is no moving image, a moving image frame corresponding to the moving amount at this time can be displayed. If it is moved continuously, it will be displayed as fast forward or fast reverse, and if a frame desired by the user is found in it, the movement may be stopped. Movie playback can be started from the displayed frame.

  Next, a second embodiment of the present invention will be described with reference to FIGS. In the first embodiment, the frame of the moving image is specified according to the horizontal movement of the camera 10, but in the second embodiment, when the movement does not move in the horizontal direction but moves in the vertical direction. Adjacent video files can be selected. In the first embodiment, the position in the X direction is detected. However, in the second embodiment, the rotation angle when the camera 10 is rotated in the horizontal direction is measured, and the frame of the moving image is designated. Like to do. Since the configuration of this embodiment is the same as the electrical configuration of the first embodiment shown in FIG. 1, detailed description thereof is omitted.

  Next, with reference to FIGS. 5 and 6, a method for reproducing a moving image in the present embodiment will be described. FIG. 5 is a diagram corresponding to FIG. 2 in the first embodiment, and shows a state where the user 20 reproduces the image of the moving image 31 recorded on the camera 10 while moving the camera 10 in the horizontal direction.

  As described above, the X-axis direction is the longitudinal direction (horizontal direction) of the camera 10, and the front of the user 20 is 0 degree, and the angle when the camera 10 is moved in the horizontal direction is θ. When the user 20 moves the camera 10 horizontally from (−θ0) to + θ0, the frame of the moving image 31 is displayed on the display element 314 in accordance with the movement of the camera 10. That is, the playback start of the video 31 is made to correspond to the angle (−θ0), the playback end to the angle (+ θ0), and the angle θ of the camera 10 is set based on the outputs of the angular velocity detection circuit 230 and the acceleration detection circuit 250 in the camera 10. The frame of the moving image 31 corresponding to the detected angle θ is displayed on the display element 314. Here, the angle θ can be obtained by integrating the angular velocity around the Y axis.

  In the present embodiment, in addition to the rotation angle θ when the camera 10 is moved in the horizontal direction, the rotation angle φ when it is moved in the vertical direction perpendicular to the horizontal direction is also detected. The file of the moving image to be reproduced is changed according to the angle φ. Here, the angle φ can be obtained by integrating the angular velocity around the X axis. FIG. 6 shows a state where the user 20 reproduces a moving image recorded on the camera 10 while moving the camera 10 in the vertical direction.

  The front of the user 20 is 0 degree, and the angle when the camera 10 is moved in the vertical direction is φ. When the user 20 moves the camera 10 vertically from (+ φ0) to (−φ0), the moving image representative images of the moving images 31 to 34 are displayed on the display element 314 according to the movement of the camera 10. That is, the moving image 31 corresponds to the angle (+ θ0), the moving image 34 corresponds to the angle (−θ0), the angle φ of the camera 10 is detected based on the outputs of the angular velocity detection circuit 230 and the acceleration detection circuit 250 in the camera 10, A representative image of the moving image file corresponding to the detected angle φ is displayed on the display element 314.

  Next, the operation of camera control in the present embodiment will be described using the flowchart shown in FIG. This flowchart is also executed by the CPU 110 based on the program stored in the flash memory 340. In this camera control flow, steps S1 to S17 and S21 to S40 are the same as the flow shown in FIG. 4 of the first embodiment. Is omitted.

  When shooting of the moving image starts in step S5 and shooting of the moving image ends in step S13, the time counted by the timer counter 132 and the moving image are recorded in association with each other in step S17, as in the first embodiment. Once this recording is performed, the file count is set to F (S18). In this file count, a moving image shot between the start and end of moving image shooting is one file, and the count F1 is incremented by one each time moving image shooting ends.

  Subsequently, REC view is performed (S19). In this step, the photographed image is reproduced on the display element 314 immediately after the photographing is completed, and the photographed image can be confirmed by the user. Details of the REC view operation will be described later with reference to FIG. When the REC view is performed, the process returns to step S1.

  If the result of determination in step S <b> 1 is that it is not a shooting mode, the mode is switched to playback mode, and normal movie playback is executed in steps S <b> 21 to S <b> 35 as in the first embodiment. If the result of determination in step S27 is that playback has not started but movement amount playback has been started as a result of determination in step S40, it is next determined whether there is a movement in angle θ and there is no movement in angle φ. Determine (S51). Here, as described with reference to FIG. 5, it is determined whether the camera 10 moves only in the horizontal direction and does not move in the vertical direction.

  If the determination condition is satisfied as a result of the determination in step S51, next, the angle θ is obtained based on the angular velocity integration (S63). Here, the output of the X-axis gyro 232 is integrated with the angular velocity signal by the angular velocity sensor processing circuit 236 to obtain the angle θ. Subsequently, frame display is performed at a timing corresponding to ((θ − (− θ0)) × T1 / 2θ0 (S65), where the angle θ obtained in step S63 and the angle of the end of the moving range (−θ0). ) And (θ0), and the frame T corresponding to the angle θ moved in the horizontal direction is read from the memory card 334 and displayed on the display element 312 using the count T1 obtained in step S15.

  If the determination condition is not satisfied as a result of the determination in step S51, it is next determined whether or not there is no movement at the angle θ and there is a movement at the angle φ (S53). Here, as described with reference to FIG. 6, it is determined whether there is no movement in the horizontal direction but only in the vertical direction. If there is movement only in the vertical direction, the movement in the vertical direction is performed. A video file can be specified according to the amount.

  If the result of determination in step S53 is that this determination condition is not satisfied, processing returns to step S25. After the representative image is enlarged and displayed in step S25, the start of reproduction is not instructed, and since there is no movement in the horizontal and vertical directions with respect to the camera 10, the display of the representative image is continued.

  If the determination condition is satisfied as a result of the determination in step S53, then the angle φ is obtained based on the angular velocity integration (S55). Here, the angular velocity signal is integrated by the angular velocity sensor processing circuit 236 with respect to the output of the Y-axis gyro 234 to obtain the angle φ.

  Subsequently, a representative image of a moving image corresponding to ((φ − (− φ0)) × F1 / 2φ0 is displayed (S57), where the angle φ obtained in step S55 and the angle of the end of the moving range ( Using −φ0) and (φ0) and the file count F1 obtained in step S18, a representative image of a moving image corresponding to the angle φ moved in the vertical direction is read from the memory card 334 and displayed on the display element 314.

  Once the representative image is displayed, file selection is performed (S59). Since the selected moving image is changed every time it moves in the vertical direction, the moving image file selection is confirmed in this step. As a method for confirming the selection of the moving image file, it may be performed by appropriately detecting the operation of the operation member for selection or detecting the movement when the camera 10 is shaken sideways. If no selection is made, the process proceeds to step S61 without selecting a moving image file.

  When file selection is processed in step S59 or frame display is performed in step S65, it is next determined whether or not to return (S61). Here, as in step S47 of FIG. 4, the “return” icon is displayed on the display element 314. In this step, it is determined whether or not the “return” icon has been touched. If the result of this determination is that the “return” icon is not touched, processing returns to step S51. Therefore, the representative image or frame of the designated moving image changes according to the movement of the camera 10.

  On the other hand, if the result of determination in step S61 is that the “return” icon has been touched, processing proceeds to step S26. In the display of the representative image in step S57 and the frame display in step S65, the representative image and the frame of the designated moving image are only displayed as a still image. However, when the reproduction is started in step S27, the designated frame is started. Movie playback starts.

  Next, the REC view in step S19 will be described using the flowchart shown in FIG. If the REC view flow is entered, first, a representative image is displayed (S81). Here, a representative image selected from the moving images taken between steps S5 to S13 is displayed on the display element 314.

  When the representative image is displayed, next, as in step S51, it is determined whether there is a movement at the angle θ and no movement at the angle φ (S85). As a result of this determination, if the determination condition is satisfied, next, as in step S63, the angle θ is obtained based on the angular velocity integration (S87). Here, the angular velocity detection circuit 230 integrates the angular velocity signal to obtain the angle θ.

  Subsequently, as in step S65, frame display is performed at a timing corresponding to ((θ − (− θ0)) × T1 / 2θ0 (S89), where the angle θ obtained in step S63 and the end of the movement range are displayed. The moving image frame corresponding to the angle θ moved in the horizontal direction is displayed using the angle (−θ0) and (θ0) of the part and the count T1 obtained in step S15.

  When the frame display in step S89 is performed or as a result of the determination in step S83, the determination condition is not satisfied, it is determined whether or not a predetermined time has elapsed (S85). The predetermined time is a time normally displayed as a REC view, for example, a time of about 2 to 30 seconds. As a result of this determination, if the predetermined time has not elapsed, the process returns to step S83, while if the predetermined time has elapsed, the original flow is returned.

  As described above, in the REC view flow according to the present embodiment, when the camera 10 is moved in the horizontal direction in the REC view display that is performed immediately after shooting a moving image, as described with reference to FIG. A moving image frame corresponding to the selected position (angle θ) is displayed. For this reason, it is possible to easily confirm the frame of the image taken with the moving image. Note that, similarly to step 27 and S33, a process for reproduction may be added, and the moving image reproduction may be started from the designated frame.

  As described above, in the second embodiment of the present invention, in addition to the horizontal movement, the vertical movement is detected (angle φ), and the moving image file is selected according to the movement amount. it can. For this reason, it becomes possible to easily search for different moving image files.

  Further, in the second embodiment, when the camera 10 is moved in the horizontal direction during the rec view display that is performed after moving image shooting, a moving image frame display corresponding to the position (angle θ) corresponding to the amount of movement is displayed. Made. For this reason, it is possible to easily check the shot moving image immediately after shooting.

  As described above, in each embodiment of the present invention, the movement in the horizontal direction and the vertical direction is detected, and when there is movement in one direction and there is no movement in the other direction, the amount of movement in one direction is determined. In response, video frames are displayed. For this reason, when playing back a moving image, it is possible to intuitively perform frame advance / return, fast forward / return, and easily read an arbitrary frame.

  Also, when trying to watch a movie at any time from the beginning to the end, operations such as fast-forward and slow-forward are troublesome, but in the embodiment of the present invention, a range in which the camera can be moved is assigned to the beginning and end of the movie. Therefore, it is possible to view the movie at an arbitrary time by appropriately moving the camera within this range. A slider operation is also conceivable as a method of reproducing a moving image within an arbitrary time. However, if the slider operation is performed while holding the portable device, both hands are required, but in this embodiment, the operation can be performed with one hand.

  In each embodiment of the present invention, when the camera is moved in the horizontal direction, the moving image frame is displayed. However, the moving image is not limited to the horizontal direction and may be in any direction. In addition, as an example of displaying a plurality of images sequentially, the case of a moving image has been described.

  In each embodiment of the present invention, the timer is counted in step S11, and the elapsed time (timer count value) and each image of the moving image are associated and recorded in step S17. However, when the frame rate of the moving image is known, the elapsed time and each image of the moving image can be associated with each other even if the counting operation by the timer is omitted. For example, when the frame rate is 30 fps, the frame is the 300th frame (image) 10 seconds after the start of shooting. In the case of continuous shooting, the continuous shooting speed is often unknown, and it is desirable to record each frame in association with the elapsed time at the time of shooting.

  In each embodiment of the present invention, the digital camera is used as the portable device. However, the camera may be a digital single-lens reflex camera or a compact digital camera, and may be used for moving images such as video cameras and movie cameras. It may be a camera, or may be a camera built in a mobile phone, a personal digital assistant (PDA), a game machine, or the like. In any case, the present invention can be applied to any portable device capable of photographing.

  The present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, you may delete some components of all the components shown by embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
