The present invention relates to an image displaying method and an editing apparatus.
When materials recorded on tapes or discs are to be edited, an operation of apparatus for reproducing video and audio data from their storage medium are searched at a high-speed as a shuttle mode to detect the record position of a target scene. Further, the apparatus is put into a so-called jog mode illustratively for frame-by-frame reproduction whereby edit points (in- and out-points) are set. With desired scene thus acquired, the next desired scene is repeatedly detected likewise. In such editing operations, it is customary to use a single video monitor wherein the desired scene is verified using images displayed thereon.
In carrying out the invention and according to one aspect thereof, there is provided an image displaying method comprising displaying one video clip or a plurality of video clips of temporally continuous material images on a screen as a first image group, displaying on the screen, when one of the video clips is selected from the first image group to request for a more detailed display of the selected video clip, image extracted at an interval of a first time period from the temporally continuous material images constituting the selected video clip as a second image group, displaying on the screen, when one image is selected from the second image group to request for a more detailed display of the selected image, image extracted at an interval of a second time period shorter than that of the first time period as a third image group, the image occurring over a time period before and after, before, or after the selected image within said second image group, then displaying on the screen, when one image is further selected from the image group displayed on the screen to request for a more detailed display of the selected image, image extracted relative to the selected image from the temporally continuous material images at an interval of a time period shorter than that of the image group including the selected image, and displaying on the screen, when one image is selected from an N-th image group to request for a more detailed image of the selected image, continuous material images occurring over a time period before and after, before, or after the selected image within the N-th image group.
FIG. 1 is a schematic view showing a configuration of an editing apparatus embodying the invention;
FIG. 1 shows a configuration of an editing apparatus 10 for editing video materials. The editing apparatus 10 has at its core an editing part 11 having functions of a switcher, an effecter, a mixer and so on. The editing part 11 is connected to a data reproducing part 12, a video monitor 13 and speakers 14 among others. The editing part 11 conducts editing processes using video and audio data retrieved by the data reproducing part 12. Images being edited are displayed on a screen of the video monitor 13 and audio data being edited is outputted from the speakers 14. The data reproducing part 12 may be a disc reproducing device such as a fixed disc drive or a removable storage medium capable of reproducing optical discs, for example. Images and audio data copied from video tapes or like medium and recorded on fixed discs, or images and audio data recorded on optical discs are retrieved therefrom and sent to the editing part 11.
Editing operations will now be described. The screen of the display device 19 connected to the computer 19 displays an icon 21 of a video clip (a temporally continuous video material) as shown in FIG. 2. The video clip icon 21 has at its center 21 a a reduced image representing the contents of the video clip, such as a reduced image of the first frame of the video clip in question. In an upper part 21 b of the image is a clip name (e.g., “Clip 1”). A time code of the first frame is shown in a lower part 21 c of the image. Illustratively, a time code “00:01:05:12” signifies 0 hour, 1 minute, 5 seconds, frame 12. When the data reproducing part 12 is a disc reproducing device capable of reproducing data from a removable storage medium such as an optical disc, the upper part 21 b may also display a disc name (e.g., “Disc 1”).
When the editing apparatus 10 is started in operation, a window 31 for displaying clip icons as shown in FIG. 3 (titled “Clip Bin” in this example) is opened on the screen of the display device 19: When the data reproducing part 12 recognizes a disc loaded therein, clip icons are created successively on the basis of data retrieved from the disc. The icons thus created are pasted as a first image group in the “Clip Bin” window 31. When the current disc is replaced by a second disc in the data reproducing apparatus 12, clip icons are created in like manner and are pasted also in the “Clip Bin” window 31. These processes are performed automatically.
When an editor selects a desired clip icon and double-clicked on the button of the mouse 18, the action is interpreted as a request for a more detailed display of images associated with the selected icon. For example, selecting and double-clicking on a clip icon 31-m titled “Disc 1/Clip 4” with a time code “00:10:33:17” opens a new window 32 titled “Disc 1/Clip 4—Interval: 15 seconds” as shown in FIG. 4. Image data are read from the disc, representing frame images at intervals of 15 seconds starting from the first frame (with a time code “00:10:33:17”) of the video clip in question. Also read from the disc are image data of the last frame. A reduced image of the icon “Disc 1/Clip 4”, reduced images of the frames extracted at intervals of 15 seconds starting from the first frame, and a reduced image of the last frame of the video clip are arranged successively as a second image group made of frame icons in the window 32. This arrangement allows the editor easily to grasp the material contents of the video clip from the first to the last frame. Each of the frame icons in the window 32 indicates a reduced image and a time code, and so does each of the frame icons to be discussed below.
When a new window 32 is displayed, the window 32 is regarded as the currently selected window while the “Clip Bin” window 31 is considered a nonselected window. In such a case, the window 32 is highlighted for its selected status (e.g., white title characters on black screen) whereas the “Clip Bin” window 31 is given a nonselected status indication (e.g., title inverted, providing black title characters on white screen) . The selected clip icon 31-m in the “Clip Bin” window 31 is highlighted for its detailed display status (e.g., outer frame shown black), and frame icon 32-1 in the window 32, which has the same image as the clip icon 31-m, is given a selected icon indication (e.g., outer frame in thick lines).
When the editor selects from the window 32 a desired frame icon and double-clicks on the button of the mouse 18, the action is interpreted as a request for a more detailed display of images associated with the selected icon. For example, selecting and double-clicking on the frame icon with a time code “00:11:33:17” opens a new window 33 titled “Disc 1/Clip 4—Interval: 15 frames” as shown in FIG. 5. Image data are read from the disc at intervals of 15 frames, representing frame images for the display duration of each frame icon in the window 32 (i.e., 30 frames for 15 seconds) in two equal portions before and after the selected frame icon 32-n. A reduced image identical to that of the frame icon 32-n, as well as reduced images of the retrieved frames are regarded as frame icons and pasted in the window 33 as a third image group. Specifically, 30 frames of reduced images for 15 seconds ranging in time code from “00:11:26:17”, “00:11:27:02” to “00:11:41:02” are pasted as frame icons in two equal portions before and after the frame with the time code “00:11:33:17.”
When a new window 33 is displayed, the window 33 is regarded as the currently selected window while the “Clip Bin” window 31 and the window 32 are considered nonselected windows. In that case, the window 33 is highlighted for its selected status while the “Clip Bin” window 31 and the window 32 are given nonselected status indications. The selected frame icon 32-n in the window 32 is highlighted for its detailed display status (e.g., outer frame shown black), and frame icon 33-p in the window 33, which has the same image as the frame icon 32-n, is given a selected icon indication (e.g., outer frame in thick lines). The clip icon 31-m in the “Clip Bin” window 31 is indicated as the window selected in the preceding step (e.g., outer frame region shaded)
When the editor selects from the window 33 a desired frame icon and double-clicks on the button of the mouse 18, the action is interpreted as a request for a more detailed display of images associated with the selected frame icon. For example, selecting and double-clicking on a frame icon with a time code “00:11:30:17” opens a new window 34 titled “Disc 1/Clip 4—Interval: 1 frame” as shown in FIG. 6. Image data are read from the disc, representing frame images at intervals of a frame for the display duration of each frame icon in the window 33 (i.e., 15 frames) in two equal portions before and after the selected frame icon 33-q. A reduced image identical to that of the frame icon 33-q, as well as reduced images of the retrieved frames are regarded as frame icons and pasted in the window 34. Specifically, 15 frames of reduced images ranging in time code from “00:11:30:10”, “00:11:30:11” to “100:11:30:24” are pasted as frame icons in two equal portions before and after the frame with the time code “00:11:30:17.”
When a new window 34 is displayed, the window 34 is regarded as the currently selected window while the “Clip Bin” window 31, window 32 and window 33 are considered nonselected windows. In that case, the window 34 is highlighted for its selected status whereas the “Clip Bin” window 31, window 32 and window 33 are given nonselected status indications. The selected frame icon 33-q in the window 33 is highlighted for its detailed display status, and frame icon 34-r in the window 34, which has the same image as the frame icon 33-q, is given a selected icon indication. The clip icon 31-m in the “Clip Bin” window 31 and the frame icon 32-n in the window 32 are indicated as the windows selected in the previous steps.
When two discs are loaded illustratively in the data reproducing part 12, a first clip icon 41-1 is pasted in an already opened “Clip Bin” window 41 as shown in FIG. 7. Where a display interval of 15 seconds is set for example, a window 42-1 titled “Disc 1/Clip 1—Interval: 15 seconds” is opened automatically. Image data representing frame images are read from the disc at intervals of 15 seconds starting from the frame position of the clip icon 41-1. A reduced image identical to that of the frame icon 41-1 and reduced images of the retrieved frames are then pasted as frame icons in a window 421.
A second clip icon 41-2 is then pasted in the “Clip Bin” window 41 as shown in FIG. 8. At the same time, a window 422 titled “Disc 1/Clip 2—Interval: 15 seconds” is opened automatically. Image data representing frame images are read from the disc at intervals of 15 seconds starting from the frame position of the clip icon 41-2. Concurrently, image data representing the last frame of the images associated with the clip icon 41-2 are read from the disc. A reduced image identical to that of the frame icon 41-2, reduced images of the retrieved frames, and a reduced image of the last frame are then pasted as frame icons in a window 422. The processing is continued in like manner. When the last clip icon 41-S is pasted in the “Clip Bin” window 41, a window 42S titled “Disc 2/Clip S—Interval: 15 seconds” is opened automatically. Image data representing frame images are read from the disc at intervals of 15 seconds starting from the frame position of the clip icon 41-S. At the same time, image data representing the last frame of the images associated with the clip icon 41-S are read from the disc. A reduced image identical to that of the clip icon 41-S, reduced images of the retrieved frames, and a reduced image of the last frame are then pasted as frame icons in a window 42S.
