Description

  The present invention relates to a technique for enlarging a part of moving image data.

  With the recent spread of digital cameras and digital video cameras, opportunities to view and print digital still image data and moving image data are increasing. When browsing these image data, a method of reducing or enlarging the image data to fit within the display screen, or displaying the image data in a certain range within the display screen at the same magnification is common.

  Under such circumstances, it has become common to select and enlarge a partial area of still image data or to cut out and save the area. As a method of selecting a partial region of still image data, there are a method of specifying any two points from the still image data displayed as a whole, a method of specifying an enlargement ratio and an enlargement location, and the like.

  For example, as a conventional technique for enlarging still image data, there is a technique that includes an enlarging operation means and a position specifying means (see Patent Document 1).

  FIG. 11 is a diagram illustrating a configuration of the back surface of the electronic still camera in Patent Document 1. In FIG.

  The electronic still camera 11 can perform enlargement setting to an arbitrary size by operating the plus button 30 and the minus button 31. Further, any position can be selected by operating the cross key 35. Further, by pressing the shutter button SB, the enlarged image can be taken into the memory card as another image. With such a configuration, it is possible to provide operability that allows the operator to operate easily and conveniently.

On the other hand, with respect to moving image data rather than still image data, it is not so common to select a part of the moving image data for enlarged display, or to cut out and save the area. In this case, a method of specifying an area in the same procedure as in the case of still image data using the first image of moving image data is considered.

  In the moving image editing program of the present embodiment, moving image editing can be performed by the flow as described above.

  Next, the enlargement setting process that is a point of the present embodiment will be described in more detail. Processing of the enlargement setting dialog in step S530 in the moving image editing program shown in FIG. 3 will be described using the flowchart of FIG. 1 and the enlargement setting dialog diagram of FIG.

  Step S100 is a determination as to whether or not the user has specified an enlargement ratio. This is processing for determining whether or not the user has specified any enlargement ratio of 8-E in FIG. If the enlargement ratio is designated, the process proceeds to step S110. If the enlargement ratio is not specified, the process proceeds to step S160.

  Step S110 is processing that moves when an enlargement ratio is designated. Here, in 8-E of FIG. 8, the process changes the color of the enlargement factor button corresponding to the designated enlargement factor and displays the enlargement factor button frame thickly.

  Step S120 is processing for placing the enlarged moving image preview 8-A in a paused state. As a result, the enlarged moving image preview 8-A is temporarily stopped regardless of the state at that time. For example, even when the enlargement ratio is changed during reproduction, the pause state is set.

  Step S130 is processing to update and display the entire area image display unit. From the moving image data, a frame image at the pause position is acquired, and the frame image is displayed as an entire region image on 8-F.

  Step S140 is processing to update and display the enlarged area. Since the enlargement ratio is newly set in step S100, processing for redisplaying the enlargement area on the all-region image display unit updated in step S130 is performed according to the set enlargement ratio.

  Step S150 is processing to update the enlarged moving image preview 8-A. Since the enlargement rate is newly set in step S100, processing for updating the preview of the enlarged moving image is performed according to the set enlargement rate.

  Step S160 is a determination as to whether or not the user has designated an enlargement location. This is processing for determining whether or not the user has designated an enlargement location in 8-F in FIG. If an enlargement location is designated, the process proceeds to step S170. If the enlargement location is not designated, the process proceeds to step S210.

  Step S170 is processing that moves when an enlargement location is designated. Here, a process for temporarily magnifying the enlarged moving image preview 8-A is performed. As a result, the enlarged moving image preview 8-A is temporarily stopped regardless of the state at that time. For example, even when the enlargement location is changed at the time of reproduction, the pause state is set.

  Step S180 is processing to update and display the entire area image display unit. From the moving image data, a frame image at the pause position is acquired, and the frame image is displayed as an entire region image on 8-F.

  Step S190 is processing to update and display the enlarged area. Since the enlargement location is newly set in step S160, processing for redisplaying the enlargement region on the all-region image display unit updated in step S180 is performed according to the set enlargement location.

  Step S200 is processing to update the enlarged moving image preview 8-A. Since the enlargement location is newly set in step S160, processing for updating the preview of the enlarged movie is performed according to the set enlargement location.

  Step S210 is a determination as to whether or not the user has operated the control button. This is a process of determining whether or not the user has operated any of the 8-C control buttons in FIG. If the control button is operated, the process proceeds to step S220. If the control button has not been operated, the process proceeds to step S260.

  Step S220 is processing that moves when the control button is operated. A process of changing the state of the enlarged video preview 8-A is performed according to the operated control. For example, when the playback button is pressed, the enlarged video preview is set in the playback state. In addition, when the pause button is pressed, the enlarged video preview is paused.

  Step S230 is processing for determining whether or not the playback state is paused as a result of the control button operation. If so, the process proceeds to step S240. If the state is other than the temporary stop, the process proceeds to step S260.

  Step S240 is a process that moves in the case of the pause state. Step S240 is processing to update and display the entire area image display unit. From the moving image data, a frame image at the pause position is acquired, and the frame image is displayed as an entire region image on 8-F.

  Step S250 is processing to update and display the enlarged area. Since the entire area image is newly updated in step S240, a process for redisplaying the enlarged area on the updated all area image is performed.

  Step S260 is a determination as to whether or not the user has operated the playback slider. This is processing for determining whether or not the user has operated the 8-D playback slider in FIG. If the playback slider has been operated, the process proceeds to step S270. If the playback slider has not been operated, the process proceeds to step S310.

  Step S270 is processing that moves when the playback slider is operated. Here, processing for updating the playback position of the enlarged moving image preview is performed according to the position of the knob of the playback slider.

  In step S280, it is determined whether or not the operation of the reproduction slider has been completed. The user can freely determine the playback position by moving the knob of the playback slider, but it is determined here whether or not the knob has been moved. If the playback slider operation is completed, the process proceeds to step S290. If the playback slider is still being operated, the process returns to step S270 to repeat the process related to the slider operation.

  Step S290 is processing that moves when the slider operation is completed. Step S290 is processing to update and display the entire area image display unit. From the moving image data, a frame image at the reproduction position after the operation of the reproduction slider is acquired, and the frame image is displayed on 8-F as an entire region image.

  Step S300 is processing to update and display the enlarged area. Since the entire area image is newly updated in step S290, a process of displaying the enlarged area again on the updated all area image is performed.

  Step S310 is processing to update the display of the enlarged moving image preview according to the reproduction state.

  In step S320, the left and right balance of the audio output is changed and output according to the distance between the center of the enlarged region and the center of the image before enlargement. As the enlargement region is located to the left of the center of the pre-enlargement image, the left sound is increased and the right sound is decreased. Conversely, as the enlargement region is located to the right of the center of the pre-enlargement image, the right sound is increased and the left sound is decreased.

  Step S330 is a determination as to whether or not to end the enlargement setting. If the [OK] button or the [Cancel] button arranged at 8-G in FIG. 8 is pressed, the enlargement setting process is terminated. If the button is not pressed, the process returns to step S100 to continue the enlargement setting process.

  With the above configuration, it is possible to set an enlarged region while displaying an entire region image of one frame of the original moving image data. Also, when the moving image data is in a paused state or when the playback slider is operated, the entire area image indicating the entire area of one frame of the moving image data before enlargement is changed, so the contents of the moving image data are grasped. You will be able to make enlargement settings.

  By these operations, it becomes possible to provide an enlargement setting means that is easy to understand and use for moving image data.

  In this embodiment, the entire area image is changed only when the moving image data is paused or when the playback slider is operated. However, high-speed image display is possible by using a CPU with high processing capability. If possible, a configuration may be adopted in which a frame image corresponding to the playback position is acquired from the moving image data for each frame in accordance with the display of the enlarged moving image preview means, and the acquired frame image is displayed and updated for each frame as an entire region image. .
