After that, the playback order is before still image # 7, and moving image # 6, which is the first image data in folder # 2, is played backward (rewind playback) from the end to the beginning at the playback speed corresponding to the rewind stage. ) And displayed. Then, the head (image) of the moving image # 5 is displayed until the user commands the stop of the rewind playback and then commands the rewind playback again.

  When the user commands stop of rewind playback and commands rewind playback again, the playback order of folders is still image # 5 which is the last image data of folder # 1 before folder # 2, and image data The still image # 4 in which the playback order is before the still image # 5 is sequentially played back and displayed for a time corresponding to the rewinding stage. Next, the moving image # 3 whose reproduction order is before the still image # 4 is reversely reproduced and displayed from the end to the beginning at the reproduction speed corresponding to the rewinding stage. Then, the still image # 2 whose reproduction order is before the moving image # 3 is reproduced and displayed only for the time corresponding to the rewinding stage. Thereafter, the playback order is before still image # 2, and still image # 1, which is the first image data in folder # 1, is played and displayed.

  As described above, when the user commands fast-forward playback, the digital still camera 1 plays back and displays the moving image to be played back from the beginning at the playback speed corresponding to the fast-forward stage, and the user performs rewind playback. When instructed, the moving image to be reproduced is reversely reproduced from the end at the reproduction speed corresponding to the rewinding stage and displayed.

  Accordingly, when a user searches for a desired moving image by instructing fast-forward playback or rewind playback of the image data recorded in the recording unit 23, the entire moving image is grasped and the desired moving image is It can be determined whether the image is a moving image. That is, the search efficiency of moving images can be improved.

  Next, fast-forward display processing performed by the digital still camera 1 in FIG. 1 will be described with reference to FIGS. This fast-forward display process is started when, for example, the user operates the display button of the operation input unit 41 to instruct display of an image.

  In step S1, the jog shuttle 61 (FIGS. 2A and 2B) of the operation input unit 41 determines whether or not fast-forward display (fast-forward playback) is commanded, that is, whether or not the jog shuttle 61 has been rotated in the direction of arrow A by the user. If it is determined and it is determined that a fast-forward display is commanded, the command is supplied to the reproduction target determining unit 83, and the process proceeds to step S2.

  In step S2, the jog shuttle 61 detects the position of the scale 61A, that is, the amount of operation (operation amount) of the user with respect to the jog shuttle 61, and determines the fast-forward stage set by the user. Specifically, when the scale 61A is from position C to position A1, the jog shuttle 61A determines the fast-forward stage as one stage, and when the scale 61A is from position A1 to position A2, the jog shuttle 61A The fast-forward stage is determined in two stages. Further, when the scale 61A is located from the position A2 to the position A3, the jog shuttle 61A determines the fast-forwarding stage as three stages. Then, the jog shuttle 61A supplies the fast-forward stage to the reproduction control unit 84 and the image acquisition unit 85, and proceeds to step S3 in FIG.

  In step S3, the reproduction target determining unit 83 determines whether or not fast-forward display is being performed, that is, whether or not the fast-forward flag indicating whether or not fast-forward reproduction is held in the RAM 34 is on. When it determines, it progresses to step S4.

  In step S4, the reproduction target determination unit 83 turns on the fast-forward flag held in the RAM 34 to indicate the presence of fast-forward reproduction, and proceeds to step S10 in FIG.

  On the other hand, if it is determined in step S3 that fast-forward display is being performed, the process proceeds to step S5, where the reproduction target determining unit 83 determines the type of image data of the folder information supplied from the folder information acquisition unit 81 and the current reproduction. Based on the target image ID, it is determined whether or not the current playback target is still image data. If it is determined that the current playback target is not still image data, that is, the current playback target is moving image data. If so, the process proceeds to step S6.

  In step S <b> 6, the reproduction target determination unit 83 determines the current reproduction based on the folder information supplied from the folder information acquisition unit 81, the current reproduction target image ID, and the reproduction position supplied from the reproduction position acquisition unit 82. It is determined whether the target moving image data is the last image data in the folder and the reproduction position is the end of the moving image data.

  That is, the playback target determining unit 83 determines whether the current playback target is the last image data in the folder from the folder information and the current playback target image ID, and determines the current playback from the playback position. It is determined whether or not the position is the end of moving image data to be reproduced.

  In step S6, when it is determined that the current reproduction target is the last image data in the folder and the reproduction position is not the end of the moving image data, the process proceeds to step S7, and the jog shuttle 61 displays the immediately preceding FIG. Whether or not the fast-forward stage determined in step S2 has changed, that is, the fast-forward stage determined in step S2 of the previous time (one time before immediately before) and the fast-forward stage determined in immediately preceding step S2 are different. Determine whether or not.

  If it is determined in step S7 that the fast-forward stage has changed, the process proceeds to step S10 in FIG.

  On the other hand, if it is determined in step S6 that the current reproduction target is the last image data in the folder and the reproduction position is the end of the moving image data, or if the fast-forward stage has not changed in step S7. If determined, the process returns to step S1 in FIG. 5 and the above-described processing is repeated.

  If it is determined in step S5 that the current reproduction target is still image data, the process proceeds to step S8, where the image acquisition unit 85 includes a fast-forward stage supplied in step S2 of FIG. Based on the time information supplied from 38, it is determined whether or not the time corresponding to the fast-forward stage has elapsed since the still image corresponding to the still image data to be reproduced is displayed on the output unit 42. .

  If it is determined in step S8 that the time corresponding to the fast-forward stage has elapsed, the process proceeds to step S9, where the reproduction target determining unit 83 determines the current reproduction based on the folder information and the current reproduction target image ID. If the target determines whether or not the playback order in the folder is the last image data, and determines that the playback order is not the last still image data, the process proceeds to step S10 in FIG.

  On the other hand, if it is determined in step S8 that the time corresponding to the fast-forward stage has not elapsed, or if it is determined in step S9 that the playback target is the last image data in the playback order in the folder, FIG. Returning to step S1 in step 5, the above-described processing is repeated.

  In step S10 of FIG. 7, the reproduction target determination unit 83 determines whether the current reproduction target is still image data based on the type of image data in the folder information and the current reproduction target image ID. If it is determined that the current reproduction target is still image data, the process proceeds to step S11.

  In step S11, the reproduction target determining unit 83 determines, based on the folder information and the current reproduction target image ID, the reproduction order (image ID number) in the folder including the still image data that is the current reproduction target. However, it is determined whether there is the next image data to be reproduced.

  In step S11, when it is determined that the next image data to be reproduced is present in the folder including the still image data to be reproduced, the process proceeds to step S12, and the reproduction target determining unit 83 is performed. Determines the next image data as a new reproduction target. For example, when the current reproduction target is the still image # 2 of FIG. 4 recorded in the recording unit 23, the reproduction target determination unit 83 sets the moving image # 3 whose image ID number is 3 as a new moving image # 3. The reproduction target is determined, and the image ID “3” of the image data that is the new reproduction target and the image data type “moving image” are supplied to the reproduction control unit 84.

  On the other hand, if it is determined in step S11 that the playback order does not include the next image data to be reproduced in the folder including the still image data to be reproduced, the process proceeds to step S13 to determine the object to be reproduced. Based on the folder information and the current reproduction target image ID, the unit 83 sets the first image data in the folder next to the folder including the still image data that is the current reproduction target to the new reproduction target folder. The reproduction target is determined, and the image ID of the image data that is the new reproduction target and the type of the image data are supplied to the reproduction control unit 84.

  After the processing of step S12 or S13, the process proceeds to step S14, and the playback control unit 84 determines that the new playback target is still image data based on the type of image data that is the new playback target supplied in step S12 or S13. It is determined whether or not.

  If it is determined in step S14 that the new reproduction target is still image data, the reproduction control unit 84 controls the recording / reproduction control unit 22 based on the new reproduction target image ID, and corresponds to the image ID. Still image data is reproduced from the recording unit 23 and supplied to the encoding / decoding circuit 21. The encoding / decoding circuit 21 supplies the still image data to the image acquisition unit 85.

  After the process of step S15, the process proceeds to step S16, and the image acquisition unit 85 controls the output control unit 36 to display a still image corresponding to the still image data supplied from the encoding / decoding circuit 21 on the output unit 42. And return to step S1 in FIG.

  On the other hand, if it is determined in step S14 that the new reproduction target is not still image data, that is, if it is determined that it is moving image data, the process proceeds to step S17, and the reproduction control unit 84 determines the new reproduction target image ID. Based on the above, the recording / reproducing control unit 22 is controlled, and reproduction of the moving image data corresponding to the image ID from the recording unit 23 is started.

  That is, the reproduction control unit 84 reproduces the moving image data from the recording unit 23 in order from the top. The recording / reproduction control unit 22 supplies the moving image data reproduced from the recording unit 23 to the image acquisition unit 85 via the encoding / decoding circuit 21.

  After the processing of step S17, the process proceeds to step S18, where the image acquisition unit 85 controls the output control unit 36 to output the moving image corresponding to the moving image data supplied from the encoding / decoding circuit 21 to the output unit 42. Display is started, and the process returns to step S1 in FIG.

  If it is determined in step S10 that the current reproduction target is not still image data, that is, if the current reproduction target is moving image data, the process proceeds to step S19, where the reproduction target determination unit 83 acquires the reproduction position. It is determined whether or not the playback position supplied from the unit 82 is the end of the moving image data that is the current playback target.

  If it is determined in step S19 that it is the end of the moving image data to be reproduced, the reproduction of the moving image data and the display of the moving image corresponding to the moving image data are stopped, and the process proceeds to step S11. The above-described processing is performed.

  On the other hand, when it is determined in step S19 that it is not the end of the moving image data that is the current reproduction target, the reproduction target determination unit 83 supplies the reproduction position supplied from the reproduction position acquisition unit 82 to the reproduction control unit 84. Then, the process proceeds to step S20.

  In step S20, the playback control unit 84 changes the playback speed of the moving image data that is the current playback target to a playback speed corresponding to the fast-forward stage supplied in step S2 of the previous FIG. Specifically, the playback control unit 84 plays back the current playback target from the recording unit 23 at the playback speed corresponding to the fast-forward stage in order from the playback position supplied from the playback target determining unit 83, and the steps of FIG. Return to S1.

  If it is determined in step S1 in FIG. 5 that the fast-forward display is not instructed, that is, if the scale 61A of the jog shuttle 61 is at the position C, the process proceeds to step S21, where the reproduction target determining unit 83 The flag is turned off and the process proceeds to step S22.

Based on the position, it is determined whether or not the current reproduction target is moving image data and the reproduction position is in the middle of the moving image data. If there is no current playback target, that is, if the fast-forward flag is off before the process of step S21, the playback target determination unit 83 determines that the fast-forward display of the moving image is not being performed.

  If it is determined in step S22 that the fast-forward display of the moving image is not being performed, the process returns to step S1, and the processes of steps S21 and S22 are repeated until the fast-forward display is commanded.

  On the other hand, when it is determined in step S22 that fast-moving video is being displayed, the reproduction target determining unit 83 supplies the reproduction position to the reproduction control unit 84, and the process proceeds to step S23.

  In step S23, the playback control unit 84 controls the recording / playback control unit 22 to start normal playback from the playback position supplied from the playback target determination unit 83 of the moving image data that is the current playback target. Here, normal playback refers to playback at a normal playback speed (single speed). The reproduction control unit 84 controls the recording / reproduction control unit 22 and supplies the reproduced moving image data to the image acquisition unit 85 via the encoding / decoding circuit 21.
