This process is a process realized by software processing in cooperation with the CPU 11 and the main processing program stored in the recording unit 17 when the power is turned on by operating the power key of the input unit 12.

  First, a mode selection screen (not shown) on which a list of modes is displayed on the display unit 15 is displayed. When a mode is selected by operating the input unit 12 (step S1), the selected mode is analyzed. (Step S2).

  When the selected mode is the shooting mode (step S3; YES), when the shutter key is operated (step S4; YES), the imaging unit 16 is controlled to capture image data by shooting (step S5). The captured image data (captured image) is recorded in the captured image recording area 171 or the recording medium 18a of the recording unit 17 (step S6), and the process returns to step S4.

  On the other hand, if the shutter key is not operated in step S4 (step S4; NO) and mode switching is instructed by the operation of the input unit 12 (step S7; YES), the process returns to step S2. When the mode switching is not instructed in step S7 and the power OFF is instructed by operating the power key (step S8; YES), this process ends. If neither instruction of mode switching or power OFF by the input unit 12 is performed (step S8; NO), the process returns to step S4.

  On the other hand, when the analyzed mode is not the shooting mode (step S3; NO) and is the moving image creation mode (step S9; YES), the moving image mode process shown in FIGS. 4 to 6 is executed (step S10). If the mode switching is instructed by operating the input unit 12 after the moving image mode processing (step S11; YES), the processing returns to step S2. If the mode switching is not instructed in step S11 and the power OFF is instructed by operating the power key (step S12; YES), this process ends. If neither the mode switching nor the power OFF operation is performed on the input unit 12 (step S12; NO), the process returns to step S10.

  On the other hand, if the analyzed mode is neither the shooting mode nor the moving image creation mode (step S9; NO), processing according to the selected mode is executed (step S13), and mode switching is instructed by operation of the input unit 12. Then (step S14; YES), the process returns to step S2. If the mode switching is not instructed in step S14 and the power OFF is instructed by operating the power key (step S15; YES), this process ends. If neither input mode switching nor power-off operation is performed at the input unit 12 (step S15; NO), the process returns to step S13.

  Hereinafter, the moving image mode process executed in step S10 will be described with reference to FIGS. This process is a process realized by software processing in cooperation with the CPU 11 and the moving image mode processing program recorded in the recording unit 17.

  In the present embodiment, the still image that is the target of moving image creation is recorded in the captured image recording area 171, but the still image recorded in the recording medium 18a may be the target.

  First, a list screen (not shown) of images recorded in the photographed image recording area 171 is displayed on the display unit 15, and when one image is selected from the list screen by the operation of the input unit 12 (step) T1: Image selection means), and the image data of the selected image (selected image) is read from the captured image recording area 171 to the work area 131 of the RAM 13 (step T2).

  Next, a condition setting method selection screen (not shown) is displayed on the display unit 15, and the setting method of the moving image creation conditions is selected by operating the input unit 12 (step T3). In this condition setting method selection screen, “manual setting”, “selection from moving image creation history”, and “selection from standard setting” are displayed as options for setting the moving image creation conditions. Any one of these setting methods can be selected by the above operation.

When “manual setting” is selected in step T3 (step T4; YES), a start area setting screen 151 is displayed on the display unit 15 (step T5).
“Manual setting” is a condition relating to a plurality of areas cut out from a selected image as a frame image of a moving image (here, the position and area size of a moving image start area cut out as the first image of a moving image, and a moving image cut out as the last image of a moving image) The user sets moving image creation conditions including the position and area size of the end area and the number of images to be cut out (number of frames) via the input unit 12. This “manual setting” is performed in steps T5 to T17 described later, and the setting means of the present invention is realized.

  FIG. 7 shows an example of the start area setting screen 151. As shown in FIG. 7, the start area setting screen 151 is a rectangle having the same aspect ratio as the moving image size (here, the same size as the selected image) set on the selected image selected in step T1. R is displayed. When the up arrow of the cross key of the input unit 12 is operated on the screen, the rectangle R is enlarged step by step according to the number of operations, and when the down arrow is operated, the rectangle is increased according to the number of operations. R is reduced stepwise. By operating the cross key, it is possible to adjust the area size of the moving image start area that is initially displayed as a moving image. When the determination key is pressed after adjusting the area size by operating the cross key, the size of the displayed rectangle R is set as the area size of the moving image start area. When the cross key is operated after determining the area size of the moving image start area, the position of the displayed rectangle R can be moved according to the operation direction and the number of times. When the determination key is pressed after moving to the position to be cut out, the displayed rectangle R is set as the moving image start area.

  Returning to FIG. 4, when the cross key of the input unit 12 is operated on the start area setting screen 151, the area size of the area to be cut out as the moving image start area is adjusted according to the operation (step T6). When the enter key is operated, the area size is set to the adjusted size (step T7; YES). Next, when the cross key of the input unit 12 is operated, the position of the area to be cut out as the moving image start area is adjusted according to the operation (step T8). When the enter key is pressed, the position of the area to be cut out as the moving image start area is set to the adjusted position (step T9).

  Next, the end area setting screen 152 is displayed on the display unit 15 (step T10). The end area setting screen 152 is the same display as the start area setting screen 151 described in FIG. 7, and the area size of the moving image end area to be displayed last as a moving image by the same operation as in the start area setting screen 151 and The position can be set. In the end area setting screen 152, it is preferable to display the already set moving picture start area.

  When the cross key of the input unit 12 is operated on the end area setting screen 152, the area size of the area to be cut out as the moving image end area is adjusted according to the operation (step T11). When the enter key is operated, the area size is set to the adjusted size (step T12; YES). Next, when the cross key of the input unit 12 is operated, the position of the area to be cut out as the moving image end area is adjusted according to the operation (step T13). When the enter key is pressed, the position of the area to be cut out as the moving image end area is set to the adjusted position (step T14).

  Next, a detailed setting screen for setting the number of frames to be cut out from the selected image selected in step T1 on the display unit 15, the playback time (playback speed) per frame, and other setting items (for example, contrast and the like) (FIG. (Not shown) is displayed, and the number of frames is set by operating the input unit 12 according to the display of the detailed setting screen (step T15), and the playback time per frame is set (step T16). When the setting items are set (step T17) and the start of moving image creation is instructed (step T18; YES), the process proceeds to step T26, and the moving image creation processing A is executed. If the start of moving image creation is not instructed and resetting is instructed (step T18; NO), the process returns to step T4.

The moving image creating process A executed in step T26 is realized by a software process in cooperation with the CPU 11 and the moving image creating process A program recorded in the recording unit 17, and the moving image creating conditions set in the manual are set. based cut means to cut out a different region of the area size from the selected image, moving image creating means for creating a moving image based on images of a plurality areas cut recording, to realize.

  In the moving image creation process A, first, reading to the work area 131 is performed based on the manually set moving image creation conditions, that is, the position and area size of the set moving image start area and moving image end area, and the set number of frames. The position and area size of each frame image to be cut out from the selected image is obtained. The area of each frame image obtained here is gradually reduced from the video start area to the video end area when the video start area> video end area, and when the video start area <video end area, From the set moving image start area to the moving image end area, the image is enlarged step by step.

  For example, if the set moving image start region is R1 shown in FIG. 8A, the moving image end region is R2 shown in FIG. 8A, and the set number of frames is 5, the moving image start region R1 <moving image Since it is the end region R2, as shown in FIG. 8A, the region sizes and positions of five frame images having different region sizes expanded stepwise from the moving image start region R1 to the moving image end region R2 are obtained.

  Next, based on the obtained position and area size of each frame image, each frame image is cut out from the selected image in the order of the area size from the moving picture start area to the moving picture end area. Is enlarged to the same size as the selected image), and the image size is unified. Then, the cut out frame images are connected in the cut out order, and the moving image creation conditions set manually, that is, the position and area size of the moving image start area and moving image end area, and the set number of frames are written in the header. A moving image file is created and recorded in the moving image file recording area (manual / history) 172 of the recording unit 17, and the process proceeds to step T56 in FIG.

  In step T56 of FIG. 4, a moving image is reproduced and output on the display unit 15 based on the created and recorded moving image file (moving image output means). In FIG. 8 (b), the moving image created when the moving image start area is set to R1 shown in FIG. 8 (a), the moving image end area is set to R2 shown in FIG. 8 (a), and the number of frames is set to 5 by manual setting. An example of screen display when a file is reproduced and output is shown. As shown in FIG. 8B, by setting the moving image creation condition such that the moving image start area is smaller than the moving image end area, the area is gradually widened away from the image in which a desired partial area in the image is enlarged. It is possible to create a moving image full of a sense of reality. In addition, by setting conditions such that the moving image start area> the moving image end area, it is possible to create a powerful moving image that makes it look like it gradually approaches a desired part of the image.

  On the other hand, when “Manual setting” is not selected from the condition setting method selection screen in Step T4 of FIG. 4 (Step T4; NO) and “Select from movie creation history” is selected (Step T19; YES), the movie A thumbnail image (history thumbnail image) of the first image of each moving image file recorded in the file recording area (manual / history) 172 is created and displayed as a list on the display unit 15 (step T20). When one thumbnail image is selected from the list of thumbnail images by the operation of the input unit 12 (step T21; YES) and the reproduction of the moving image is instructed (step T22; YES), the moving image corresponding to the selected thumbnail image is displayed. The file is played back (step T23). When the start of movie creation under the same movie creation conditions as the selected thumbnail image is instructed (step T24; YES), the movie creation conditions recorded in the header of the movie file corresponding to the selected thumbnail image are displayed in the work area. 131 is read (step T25), and the above-described moving image creation process A is executed based on the read moving image creation conditions (step T26), and a moving image is reproduced on the display unit 15 based on the created moving image file. Is output (step T56; moving image output means).

  On the other hand, in step T19 in FIG. 4, when “select from moving image creation history” is not selected (step T19; NO) and “select from standard setting” is selected (step T27 in FIG. 5; YES), display unit 15 A standard moving picture selection screen (not shown) is displayed on the screen (step T28). When “zoom moving picture” is selected from the standard moving picture selection screen in response to an operation from the input unit 12 (step T29; YES), processing is performed. Shifts to Step T33.

  In step T33, a moving image that zooms up from the entire selected image toward the specified region (moving image end region) or a moving image that zooms back from the specified region (moving image start region) to the entire image is displayed. When a zoom selection screen (not shown) for selecting whether to create an image is displayed and zooming-in is instructed by operating the input unit 12 (step T33; YES), the zoom end region setting screen is displayed on the display unit 15 Is displayed (step T34).

  Although not shown, the zoom end area setting screen is substantially the same as the start area setting screen 151 shown in FIG. 7, and a screen in which a rectangular area having a preset size is displayed on the image selected in step T1. It is. The size of the rectangular area is fixed. On the zoom end area setting screen, when the rectangular area displayed by operating the cross key of the input unit 12 is moved to a desired position and the enter key is pressed, the displayed rectangular area is displayed. The region is set as a region to be cut out as the last image of the moving image, that is, a moving image end region of the zoom moving image.

  When the position of the moving image end area is set from the zoom end area setting screen by the operation of the input unit 12 (step T35: end area setting means) and the start of moving image generation is instructed (step T36; YES), the moving image generation process B is performed. It is executed (step T37).

The moving image creating process B executed in step T37 is realized by software processing in cooperation with the CPU 11 and the moving image creating process B program recorded in the recording unit 17, and from all areas of the selected image, step T35 is executed. implementing clipping means to cut out a plurality of areas while reducing the stepwise region size to reach the movie finished area set, video creation means for creating a moving image based on images of a plurality areas cut recording, the in .

  In the moving image creating process B, first, an area to be cut out as each frame image is obtained based on the position of the moving image end area set in step T35 and the preset number of frames. Specifically, a plurality of areas (for a preset number of frames) whose area size is reduced stepwise from the entire area of the image selected in step T1 to the moving image end area set in step T35 are obtained. It is done.

  For example, when the set moving picture end area is R3 shown in FIG. 9A and the preset number of frames is 5, the moving picture end area is changed from the whole area of the image as shown in FIG. 9A. The area sizes and positions of the five frame images obtained by reducing the area size in stages up to R3 are obtained.

  Next, the obtained large area is sequentially cut out, the cut out image is enlarged to the moving image size, and the image size is unified. Then, the frame images are connected in the cut-out order to create a moving image file and recorded in the moving image file recording area (standard) 173 of the recording unit 17, and the process proceeds to step T56 in FIG. In step T56, a moving image is reproduced and output on the display unit 15 based on the created moving image file (moving image output means).

  FIG. 9B shows a case where the movie end area is set to R3 shown in FIG. 9A and the movie file of the zoom-up movie created when the preset number of frames is 5 is reproduced and output. An example of screen display is shown. The user can select a zoomed-up moving image from the standard settings and set the moving image end area. As shown in FIG. 9B, the user has a powerful force to gradually approach a desired part of the image. A moving image can be easily created.

  On the other hand, when zoom back is instructed from the zoom selection screen (step T33; NO), the zoom start area setting screen is displayed on the display unit 15 (step T38).

  Although not shown, the zoom start area setting screen is substantially the same as the start area setting screen 151 shown in FIG. 7, and a screen in which a rectangular area having a preset size is displayed on the image selected in step T1. It is. The size of the rectangular area is fixed. On the zoom start area setting screen, when the rectangular area displayed by operating the cross key of the input unit 12 is moved to a desired position and the enter key is pressed, the displayed rectangular area is displayed. The area is set as an area to be cut out as the first image of the moving image, that is, a moving image start area.

  When the position of the moving image start area is set from the zoom start area setting screen by the operation of the input unit 12 (step T39; start area setting means), and the start of moving image generation is instructed (step T40; YES), the moving image generation process C is performed. It is executed (step S41).

The moving image creating process C executed in step T41 is realized by software processing in cooperation with the CPU 11 and the moving image creating process C program recorded in the recording unit 17, and from the area set in step T39. cut out to cut out means a plurality of regions enlarged stepwise area size until the entire area of the selected image, to create a moving image based on the image of the plurality of regions cut out to achieve a moving image creating means for recording.

  In the moving image creation process C, first, the area of each frame image is obtained based on the position of the moving image start area determined in step T39 and the preset number of frames. Specifically, a plurality of (for a preset number of frames) areas whose area size is gradually increased from the moving image start area set in step T39 to the entire area of the image selected in step T1 are obtained. It is done.

  For example, when the set moving image start area is R4 shown in FIG. 10A and the preset number of frames is 5, as shown in FIG. 10A, all the images are displayed from the moving image start area R4. The area size and position of five frame images whose area size has been gradually increased to the area are obtained.

  Next, the obtained regions are sequentially cut out from the smallest ones, and the cut out images are enlarged to the moving image size to unify the image size. Then, the frame images are connected in the cut-out order to create a moving image file and recorded in the moving image file recording area (standard) 173 of the recording unit 17, and the process proceeds to step T56 in FIG. In step T56, a moving image is reproduced and output on the display unit 15 based on the created moving image file (moving image output means).

  FIG. 10B shows a case where a movie file of a zoom-back movie created when the movie start area is set to R4 shown in FIG. 10A and the preset number of frames is five is reproduced and output. An example of screen display is shown. As shown in FIG. 10B, the user selects a zoom-back moving image from the standard settings and designates a moving image start region. As shown in FIG. It is possible to easily create a moving image with a sense of reality that makes it appear to spread away.

  When “rotating moving image” is selected instead of “zoom moving image” (step T29; NO) from the standard moving image selection screen (step T30; YES), the process proceeds to step T42. Here, as shown in FIG. 11, the “rotation video” is the rotation set from the set rotation start position, when the number of frames, the rotation start position, and the rotation direction are set. The image area is gradually expanded from the rotation start position to the set rotation direction and displayed during playback. It will appear as if the entire image was displayed at the end.

  In step T42, an input screen for the number of frames is displayed on the display unit 15. When the number of frames is input by the operation of the input unit 12, the number of frames for which the image selected in step T1 is input is displayed on the display unit 15. A rotation moving image setting screen divided into areas is displayed (see FIG. 11A), and rotation starts as a rotation start point by operating the cross key and the enter key of the input unit 12 from the rotation moving image setting screen. When the position (start position) is set (step T43), the rotation direction is further set (step T44), and the start of moving image generation is instructed (step T45; YES), the moving image generation processing D is executed (step S45). T46). The number of frames, the start position, and the rotation direction may be set automatically.

The moving image creating process D executed in step T46 is realized by software processing in cooperation with the CPU 11 and the moving image creating process D program recorded in the recording unit 17, and an area to be cut out from the selected image is stepped. A moving means is created based on the cut- out images of the plurality of cut- out areas, the cut-out means for cutting out a plurality of cut- out areas until the cut-out area becomes the entire image in a stepwise manner from the start position set in T43 to the rotation direction set in step T44. Realizes moving image creation means for recording .

  In the moving image creation process D, first, the selected image selected in step T1 is divided into areas of the set number of frames. Next, the image area at the set start position is cut out. Next, the combined image area and the area adjacent to the rotation direction are sequentially extracted, and when the extracted area becomes the entire image, the extracted images are connected to create a movie file. The video file recording area (standard) 173 of the recording unit 17 is recorded.

  For example, if the set conditions are frame number = 5, start position = upper left area (area 1 in FIG. 11A), and rotation direction = clockwise, area 1 in FIG. 11A is first cut out. Next, regions 1 to 2 are cut out, then regions 1 to 3 are cut out, then regions 1 to 4 are cut out, then regions 1 to 5 are cut out, and then all the regions are cut out and cut out. A plurality of images are connected to create a moving image file.

  Note that display position information of each frame image is recorded in the header of the moving image file. Based on this display position information, an image can be developed and displayed stepwise in the rotation direction from the rotation start area during reproduction.

  In the moving image creation process D, when a moving image file is recorded, the process proceeds to step T56 in FIG. In step T56, a moving image is reproduced and output on the display unit 15 based on the created moving image file (moving image output means).

  In FIG. 11B, the set condition is the number of frames = 5, the start position = upper left area (area 1 in FIG. 11A), and the rotating moving image file created with the rotation direction = clockwise is reproduced and output. An example of the screen display when this is done is shown. As shown in FIG. 11B, the image is gradually displayed clockwise from the region 1, and finally the entire image is displayed. In this way, the “rotating moving image” gradually expands the image in the rotation direction and finally displays the entire image, so that a sense of perspective can be obtained. It should be noted that the area 1 in FIG. 11A is cut out, enlarged so as to fit in the display unit 15 and displayed in the center, and this processing is sequentially performed on each of the images after the area 2 in FIG. It may be.

  On the other hand, when “vortex moving image” is selected instead of “rotating moving image” (step T30; NO) from the standard moving image selection screen (step T31; YES), the process proceeds to step T47. Here, as shown in FIG. 12, the “vortex moving image” is a rotation set from the set start position to the area cut out from the selected image when the rotation start position (start position) and the rotation direction are set. The image area is spirally expanded from the set rotation start position to the set rotation direction at the time of playback. It expands and expands, and finally it looks as if the entire image is displayed.

  In step T47, the spiral moving image setting screen in which the image selected in step T1 is divided into a plurality of preset areas (here, 20 areas) is displayed on the display unit 15 (FIG. 12). (Refer to (a)), the start position as the rotation start point is set by operating the cross key and the enter key of the input unit 12 from this spiral moving image setting screen, and the rotation direction is set (step T48), and the moving image start is started. Is instructed (step T49; YES), the moving image creating process E is executed (step T50). Note that the start position and the rotation direction may be set automatically.

The moving image creating process E executed in step T50 is realized by software processing in cooperation with the CPU 11 and the moving image creating process E program recorded in the recording unit 17, and an area to be cut out from the selected image is stepped. A moving image is created on the basis of the cut- out means for cutting out a plurality of cut- out means from the start position set in T47 in a spiral shape in the rotation direction set in step T48 until the cut-out area becomes the entire image. A moving image creating means for recording is realized.

  In the moving image reproduction process E, the selected image selected in step T1 is divided into a plurality of preset areas. Next, the image area at the set start position is cut out. Next, the combined image area and the area adjacent to the rotation direction are sequentially cut out, and when the cut out area becomes the entire image, the cut out image is connected to create a movie file, It is recorded in the moving image file recording area (standard) 173 of the recording unit 17. Note that display position information of each frame image is recorded in the header of the moving image file. Based on this display position information, an image can be developed and displayed in the rotation direction from the rotation start area during reproduction.

  In the moving image creation process E, when a moving image file is recorded, the process proceeds to step T56 in FIG. In step T56, a moving image is reproduced and output on the display unit 15 based on the created moving image file (moving image output means).

  FIG. 12B shows a screen display example when a moving image file of a spiral moving image created with the set conditions as start position = lower left region and rotation direction = clockwise is reproduced and output. As shown in FIG. 12B, the image is developed in a spiral shape clockwise from the lower left of the screen, and finally the entire image is displayed. In this way, the “Swirl Movie” expands the display of the image in a spiral shape in the rotation direction and finally displays the entire image, so the perspective of the image attracts the viewer's interest at the center of the spiral. Can be emphasized.

Note that the center position of the spiral may be set by the user. Further, the display speed may be set.
Also, the lower left area at the start position in FIG. 12A is cut out and enlarged so as to fit in the display unit 15 and displayed in the center. This processing is performed for each of the images after the next area in FIG. May be performed sequentially.

  On the other hand, when “afterimage moving image” is selected (step T31; NO) instead of “vortex moving image” (step T31; NO) from the standard moving image selection screen, the process proceeds to step T51. If “afterimage moving image” is not selected (step T32; NO), the process returns to step T27.

  Here, “afterimage moving image” means that when a rotation start position (start position), a rotation direction, and an overlap level are set, an area is shifted from the set start position to the set rotation direction according to the overlap level. The image is cut out (see FIG. 13), and is displayed while shifting the display area in the rotation direction so that the area of the image displayed before and the area of the image displayed next are overlapped according to the overlap level at the time of reproduction. is there. For example, when the overlap level is ½, a half area of the displayed image is displayed so as to overlap with a previously displayed image area.

  In step T51, an afterimage moving image setting screen in which the image selected in step T1 is divided into areas having a preset number of frames is displayed on the display unit 15 (not shown). The start position is set by operating the twelve cross keys and the enter key, then the rotation direction is set (step T52), and a list of overlapping levels (here, 1/2, 1/3, and 1/4 levels) Is displayed, and the overlap level is set (Step T53). When the start of moving image creation is instructed (Step T54; YES), the moving image creation processing F is executed (Step T55).

  In the moving image reproduction process F, first, an image region at the start position set in step T51 (with the same aspect ratio as that of the original image) is cut out from the image selected in step T1 so as to fit in the display unit 15. Then, the image area is moved in the rotation direction set in step T52 by an amount corresponding to the set overlap level, and an image area to be cut out next is obtained, and the obtained image area is cut out and displayed. Enlarged to fit in 15. This process is repeated, and when the image area has been cut out once, the cut out images are connected to create a moving image file and recorded in the moving image file recording area (standard) 173 of the recording unit 17. Note that display position information of each frame image is recorded in the header of the moving image file. Based on this display position information, an image is displayed in the rotation direction from the start area during reproduction.

  In the moving image creation process F, when a moving image file is recorded, the process proceeds to step T56 in FIG. In step T56, a moving image is reproduced and output on the display unit 15 based on the created moving image file (moving image output means).

  When the reproduction output of the moving image ends, the process proceeds to step S11 in FIG. The digital camera 10 has a moving image playback mode. When the moving image playback mode is selected in step S1 in FIG. 3, the selected moving image file is selected from the moving image files recorded in the recording unit 17 in step S13. Playback output can be performed.

  As described above, according to the digital camera 10 of the present invention, when an arbitrary image to be used for moving image creation is selected from among a plurality of still images photographed via the input unit 12, a selection is made. A plurality of regions having different region sizes are cut out from the obtained images, and the cut images are connected to create, record, and output a moving image. Therefore, it is possible to reproduce and output a perspective moving image from any shot still image.

  In addition, since the user can set moving image creation conditions regarding a plurality of regions cut out from an arbitrary image, the user can create a desired moving image.

  In addition, since the moving image creation conditions at the time of creating a moving image are recorded in the header area of the moving image, it is possible to create a moving image according to the conditions when creating a moving image from another image. It is possible to save the trouble of setting conditions when creating a moving image, and the operability is improved.

  Also, you can create a moving image that is zoomed up to the set area from the entire image simply by setting the area to be cut out as the last image of the moving image, so that you can gradually approach a desired part of the image. A powerful moving image can be easily created.

  In addition, it is possible to create a moving image that is zoomed back from the set area to the entire image simply by setting the area to be cut out as the first image of the moving image. From this, it is possible to easily create a moving image full of realism that gradually expands the area and moves away.

  Also, if you select “Rotating video” and set the number of frames, start area, and rotation direction, the area to be cut out from one image is expanded stepwise from the set start position to the set rotation direction, and cut out. Since a moving image is created by cutting out multiple areas until the entire area becomes the entire image, during playback, the image is gradually expanded in the rotation direction, and finally the entire image is expanded. Is possible.

  In addition, if you select “Swirl Movie” and set the start area and the rotation direction, the area to be cut out from one image will be cut out by expanding the area to be cut out spirally from the set start position to the set rotation direction. Since a moving image is created by cutting out a plurality of areas until the entire area becomes the entire image, when the moving image is played back, the image is gradually expanded in a spiral shape in the rotation direction, and finally the entire image is expanded to the center of the spiral. It is possible to enhance the perspective of the image by attracting the viewer's interest.
