BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for displaying a moving image at a glance for quickly understanding the contents of the moving image .

[0002]

2. Description of the Related Art To understand the contents of a conventional moving image, it is usual to watch the moving image by playing it back normally, or to see the contents at a glance. On the other hand, there is a method of reminding the contents by displaying a typical screen as a still image recently.

[0003]

However, according to the conventional method, a method of quickly displaying a moving image for searching for a specific scene is as follows.
There is a problem that it takes time and effort to search for the desired part without skill and prior understanding of the contents.

[0004] It is an object of the present invention to provide a moving picture quick display method in which the contents of the moving picture can be understood at a glance.

FIG. 1 is an elevational view of an example of a figure showing a frame which changes according to a camera operation used in a quick display method of the present invention. In this figure, frame 2 corresponding to each frame of the moving image
Is shown as a three-dimensional solid whose time elapses from the front toward the upper right. Also, when the size of the frame 2 changes in this figure, it corresponds to the change in the enlargement ratio of the screen. When the frame 2 becomes smaller, the enlargement ratio increases, and when it becomes larger, the enlargement ratio decreases. Is equivalent to that. Furthermore, in order to make it easier to understand the overall time progress, a progress display line 3 connecting the four corners of the frame 2 in time is shown here. This is a case where an expression indicating which range is to be taken based on the top screen is used. If this is an expression indicating what size the top screen corresponds to, the case where the frame 2 becomes smaller corresponds to a decrease in the enlargement ratio, and the case where the frame 2 becomes larger corresponds to an increase in the enlargement ratio. become. The difference in the interpretation causes a difference in the meaning of the size of the frame 2. Here, the former will be described as an example. Also, here, the size of the frame 2 is changed in response to the change in the speed with the increase or decrease of the enlargement ratio. If the size of the frame 2 is not different from the first screen, there is no change in the enlargement ratio. , The change in magnitude is proportional to or corresponds to the rate of change of the magnification. In addition, the number of the frames 2 becomes complicated and difficult to understand when drawn corresponding to all the frames. Therefore, it is often preferable to appropriately reduce the number of frames. FIG. 1 shows a case where the image is enlarged by a zoom operation. Here, since the size of the frame 2 is changed according to the zoom speed, the maximum zoom speed is obtained with the frame 2 having the minimum size. When the zoom operation is completed, the size of the initial frame 2 becomes the same. In this way, the frame 2 does not become extremely small or extremely large due to the zoom operation, and the display is not affected by the previous camera operation.

FIG. 2 shows an example in which a screen is given to this for quick viewing.
4 to FIG. FIG. 2 shows a case where a plurality of representative screens 1 extracted from a large number of screens in a moving image are positioned in the top frame 2. It can be seen that there is a representative screen 1 in FIG. In order to see this at a glance, when a quick operation instruction is given, several representative screens 1 in the middle of the video are shown, and the last representative screen 1 is sequentially displayed. FIG. 3 shows an example of the screen display during this process.
In FIG. 3, from the top representative screen 1 to the present representative screen 1, the frame 2 is an expression that is not hidden by the representative screen 1, and the subsequent frames 2 are expressions that are partially hidden in the screen and are represented by intermediate representative screens. It is made clear that there is one. Here, a frame 2 from the leading representative screen 1 to the currently displayed representative screen 1
Is a dotted line, so that an extra line generated on the representative screen 1 is inconspicuous, or the frame 2 on the representative screen 1 is omitted. Is possible. Further, the representative screen 1 of FIG. 3 is displayed smaller than the representative screen 1 of FIG. This size is displayed in accordance with the reduced frame 2 by a zoom operation, so that a viewer who normally does not care about the camera operation can strongly recognize the operation.

FIG. 4 shows a case where the representative screen 1 is at the end,
From the first representative screen 1 to the representative screen 1 just shown, the frame 2 is not hidden behind the representative screen 1 so that the representative screen 1 is found at the end. By sequentially showing several representative screens 1 shown in this way, it is possible to quickly view the outline of the video. In addition, in this quick preview method, since a camera operation can be used as a guide when pointing to a specific location in a video, it is possible to specify a video location more accurately by using this.

In the above description, the zoom operation icon is used. Next, another camera operation will be described.
Basically, the camera operation is called tilt and pan when the camera is shaken vertically and horizontally when the camera is fixed, fixed when the camera is fixed, and zoom when the lens changes the magnification. Operations for moving the camera in the front-rear direction, the left-right direction, and the up-down direction are called dolly, truck, and boom. As the camera operation information, there are a method of accumulating information of a sensor attached to the camera itself at the time of photographing together with moving image information, and a method of taking image data from a photographed moving image by video processing. In the former case, a special camera with a sensor may be manufactured and stored in an audio track of a video tape. Also,
For the latter, the method disclosed in Japanese Patent Application No. Hei 3-12629 can be used. Where zoom and dolly, pan and track,
Since there is no distinction between tilt and boom, they are treated as the same classification.

FIG. 5 shows icons 50 for continuous camera operation when a combination of fix (F), pan (P), and tilt (T) is used. The range 5 of each camera operation and its operation name are indicated by a symbol (fix: F) on the left of the icon 50.
1 to F4, pan: P1, P2, tilt: T1). In the icon 50 expressed in this manner, the point at which the camera operation is performed is indicated on the icon 50, so that the standard becomes clear. 4 is a virtual line when the camera operation in the fixed state continues.

FIG. 6 shows an icon 50 in which a plurality of representative screens 1 are assigned to FIG. Here, the frame 2 of the figure is erased in front of the representative screen 1. In this case, the screen mainly displays the screen of the changing point of each camera operation. This selection criterion can be changed depending on the purpose. For example, there are a method of increasing the display frequency in a place where the movement is large, and a method of decreasing the frequency in a place where the movement is small, a method of displaying the cut position, and the like. Here, reference numerals a to e in FIGS. 5 and 6 indicate an end point or a development point of the camera operation, respectively, a is an end point of the pan operation to the left, b is a start point of the pan operation to the right, c is the start point of the left pan operation, d is the start point of the upward tilt operation, and e is the start point of the downward tilt operation. These points have a mixture of a start point and an end point. FIG. 6 shows the representative screen 1 which was previously selected among the start point and the end point of each camera operation.
This is an example in which a screen in which the hidden portion is reduced is selected as the next representative screen 1. By arranging a plurality of representative screens 1 in this manner, an outline of the video can be easily associated.

Although the camera operation has been shown in addition to the figures so far, even when the camera operation has not been collected as information, the plurality of representative screens 1 of the icons 50 can be put in the frame 2 to understand the image. Useful. FIG. 7 shows an icon 50 when camera operation has not been performed, and the frame 2 of all figures is treated the same as a fix. Representative screen 1
Can be associated with the outline of the video and can be viewed at a glance. By showing one or more of these screens as a moving image, it is possible to understand the outline of the necessary screen in more detail.

[0019]

According to the present invention, the elapse of time in a moving image
Has a time axis of the frame combination corresponding to each frame of
As well as multiple screens in the video
Multiple representative screens extracted from the
Batch display corresponding to the frame of the temporal position in the figure
Since so that, it is possible to allow association of content from the display, so that the temporal position from the position of figure frame of each representative picture can be seen.

In addition, the time lapse in a moving image is determined by each frame of the moving image.
The figure has a time axis of a combination of frames corresponding to the
And extracted from many screens in the video.
Multiple representative screens in the figure of the frame combination
Since the images are sequentially displayed in correspondence with the frame of the temporal position, the relationship between the position of the graphic in the frame of the icon and the content can be grasped, and the appropriate position can be designated. The speed of the camera operation in the moving image is determined based on the fixed operation, and the positional shift with respect to the frame and the change in the size of the frame indicate each camera operation. .

Further, the frame corresponding to each frame of the moving image
When showing a figure with a combination time axis,
Each video in the movie according to the speed and direction of camera operation in
Change the position and size of the frame corresponding to the frame
It allows further has the characteristic that tends sensuously understand that.

In addition, a large number of screens in a moving image are extracted.
The size of the representative screens in proportion to the size of the frame
As well as the temporal
By displaying the position corresponding to the position frame, the relationship between the front and rear of the screen can be clearly understood.

Further, when displaying a plurality of representative screens, instead of randomly extracting the screens, the representative screens when those camera operations are changed to other camera operations are displayed in order to associate the screens with the camera operations. To be used, and
By displaying the image corresponding to the frame indicating the elapsed time, a representative screen corresponding to the camera operation can be attached to the icon. This makes it possible to display icons that are easier to see.
