DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for displaying a still image which allows the user to understand at a glance the contents of a moving image.

[0002]

2. Description of the Related Art In a conventional moving picture, it is a usual method to understand the contents of the moving picture by playing back the moving picture itself or watching it at a quick 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, it is difficult to use the conventional method as a means for searching for a specific scene or changing a moving image.

SUMMARY OF THE INVENTION The object of the present invention is to operate a camera of a moving image at a glance.
WorkUnderstandingTo provide a video content display methodAh
You.

[0005]

According to the present invention, there is provided a moving image content displaying method for displaying a time lapse in a moving image.
The frame of the frame for each frame inside
It is shown as a three-dimensional solid whose time elapses toward
In order to show the speed and direction of the camera operation in the video
Fixed position and size of the frame of each frame
This is changed and displayed based on the time of operation.

[0006] Further, the above-mentioned tertiary order indicating time elapse in a moving image.
It is to display the original three-dimensional and representative picture frame the three-dimensional solid is representative of video including in correspondence between positions when the frame.

[0007] Further, the above-mentioned 3 which indicates a lapse of time in a moving image.
And dimension stereoscopic representative screen frame the three-dimensional solid is representative of video encompasses Upon displaying in correspondence with the position of the frame, the display size of the representative screen frames representative of the video frame of said frame It is the same as the size.

[0008] Further, in displaying a screen frame representative of moving to correspond to the position of the frame, as it is the frame for the frame at the rear in time than the representative screen frames representative of the video The frame which is displayed, and which is temporally earlier , does not display or has a broken line shape for the frame portion of the frame which overlaps the representative screen of the frame representing the moving image.

[0009] Further, the above-mentioned 3 indicating the time lapse during the moving image.
The screen of the frame at the time when the camera operation of the moving image included in the three-dimensional solid changes to the three-dimensional solid is displayed in correspondence with the temporal position of the frame.

[0010] In addition, the three-dimensional standing of the time lapse in a moving image is described.
When a camera operation other than the fix operation is performed when displaying by the body, a virtual line corresponding to the fix operation is displayed.

In the present invention, the camera operation can be understood at a glance from the temporal change of the frame size. In addition, since the representative screen is displayed corresponding to the temporal position of the three-dimensional solid, the content indicated by the icon can be immediately associated. Further, since the display size of the representative screen and the size of the frame of the frame are set to be the same, it is easy to intuitively understand. Further, the frame that is temporally ahead of the representative screen is not displayed or has a broken line shape, so that the screen is easy to see. Further, the screen at the time the three-dimensional camera Video interactions include changes frame, since in correspondence between positions when the frames can be associated with the screen corresponding to the camera operation icon . In addition, since the speed, direction, and type of the camera operation are shown on the basis of the fixing operation, the screen can be easily understood.

As described above, when the moving image content display method according to the present invention is used, a graphic representing the speed and direction of the representative screen and camera operation (hereinafter referred to as a graphic) is converted into a still image (hereinafter referred to as an icon). Because it is shown, the contents of the moving image can be read at a glance and can be used as a means for using the camera operation for editing.

[0013]

FIG. 1 is an elevational view showing an example of a figure with a representative screen omitted using the moving image content display method of the present invention. In this figure, the frame 2 corresponding to each frame of the moving image is shown as a three-dimensional solid whose time elapses from the near side to the upper right. Also, when the size of the frame 2 changes in this figure, it corresponds to a change in the enlargement rate of the surface, and when the frame 2 becomes smaller, the enlargement rate increases, and when it becomes larger, the enlargement rate decreases. It is equivalent to having. Furthermore, in order to make it easier to understand the overall time course, 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 speed accompanying the increase or decrease in the enlargement ratio. If the size of the frame 2 is not different from the first screen, the change in the enlargement ratio is Instead, the change in magnitude is proportional 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 in correspondence with 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. With this configuration, 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. In addition, 50 is an icon.

FIGS. 2 to 4 show examples of icons 50 to which a representative screen is added. FIG. 2 shows a case where the representative screen 1 is at the top, and the subsequent frames 2 are such that the representative screen 1 is at the top as an expression partially hidden in the representative screen 1. FIG. 3 shows a case where the representative screen 1 is in the middle. The frame 2 is an expression that is not hidden by the representative screen 1 from the first screen to the representative screen 1, and the subsequent frames 2 are expressions that are partially hidden by the representative screen 1. , There is a representative screen 1 in the middle. Here, by making the frame 2 from the top screen to the representative screen 1 a dotted line, an extra line generated on the representative screen 1 is made inconspicuous, and even if the line of the frame 2 on the representative screen 1 is omitted, It is possible to use an expression that makes it possible to determine that the representative screen 1 has the representative screen 1. FIG. 4 shows a case where the representative screen 1 is the last one, and the frame 2 is not hidden behind the representative screen 1 from the top screen to the representative screen 1 so that the representative screen 1 can be understood at the end. Such a displayed icon 50 has a feature that the representative screen 1 is present in a three-dimensional display including time information, so that the time position is clear and the position of the display screen 1 is easy to understand.

FIG. 5 shows a frame 2 of a frame showing a case where the image is reduced by the zoom operation, in which the representative screen 1 is not shown. By giving the representative screen 1 thereto as shown in FIGS. 2 to 4, the icon 50 at the time of reduction can be expressed.

Although the icons 50 have been described for zooming, expressions for other camera operations will now be described. By the way, the camera operation basically consists of tilting the camera vertically and shaking it horizontally at a fixed position.
The pan is called fixed, the fixed state is called fixed, and the change in the magnification by the lens is called zoom. Operations for moving the camera in the front-back 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 storing information of a sensor attached to the camera itself at the time of shooting together with moving image information, and a method of obtaining image information from a shot moving image by video processing. In the former case, a camera with a special sensor may be manufactured and stored in an audio track of a video tape. For the latter, the method described in Japanese Patent Application No. Hei 3-12629 can be used.

FIG. 6 shows a pan (P) operation icon 50. Here, following the fix (F) 20, the pan (P)
Is performed, the pan (P) has a portion 21 that initially accelerates, a portion 22 where a constant speed pan (P) is performed next, and a portion 23 where the pan (P) slows down next. Further, following the fix (F) 24, a series of operations ends. Here, in the range of the pan (P), each frame 2 has moved to the right, which indicates that the camera has turned to the right. When the camera is directed to the left, the frame 2 is moved in the opposite direction. In this way, a dolly operation expressing a pan operation can be similarly expressed. Here, the dotted line 4 is a virtual line indicating the case where the camera operation in the fixed state is continued, and the direction of movement becomes clear by the existence of the virtual line 4. The greater the degree of separation from the virtual line 4, the faster the speed of the camera operation. In FIG. 6, the operation names of the respective camera operation ranges 5 are indicated by F and P in order to make the description easy to understand.
However, the original icon 50 does not necessarily need to indicate this range. Icon 5 expressed in this way
In the case of 0, the outline of the scene can be associated with the representative screen 1 and the temporal classification of details by the camera operation becomes possible. By designating the frame 2 of the frame of the icon 50 with a cursor or the like, a device that designates a specific frame to the machine can accurately specify the position of the frame. If each camera operation has a linear portion, it may be an operation at a constant speed or a range having a constant acceleration. When the linearity is poor, it indicates that the panning operation is not smooth, and the moving image is often difficult to see, so that the quality of the image can be determined. In addition, if the machine is instructed to change the length of the straight part if it is too long or too short, the editing of the moving image can be facilitated by thinning out frames from the moving image or adding frames appropriately. become able to.

FIG. 7 shows icons 50 for continuous camera operation when the fix (F), pan (P), and tilt (T) are combined. The range of each operation and the operation name are shown to the left of the icon 50. Since there is no distinction between zoom and dolly, pan and track, tilt and boom, they are treated as the same classification. However, the icon 50 represented in this way allows the representative screen 1 to be associated with the outline of the scene, and allows temporal classification of details by operating the camera. Further, when a plurality of screens are displayed, the screens are not extracted at random, but are associated with the camera operation and the screen when a specific camera operation is changed to another camera operation is used. In FIG. 8, a screen 10 of a frame corresponding to a change point of each camera operation is separately indicated by a leader line 11 so that the icon 5 is displayed.
The development of 0 is made easier to understand. This makes it possible to display icons that are easier to see.

Further, as shown in FIG. 9, by arranging a plurality of icons 50a, 50b, etc., it is possible to understand at a glance a moving image of a certain length,
It will help you understand the video and use it as an aid to editing.

[0020]

According to the present invention, the lapse of time in a moving image is determined by the third order.
Shown as original stereoscopic, Videos this and Figure positions relative to the frame rate of the camera operation in a moving relative to the fix operation, the elapsed time-by showing the camera operation by a change in size of the frame Is represented as a still image, so that the user can understand the camera operation of the moving image at a glance.

Also, a three-dimensional stand indicating a time course in a moving image is displayed.
A representative screen of a frame representing the moving image is displayed on the body corresponding to the temporal position of the frame. This makes it possible to associate the contents indicated by the icon with one another, and to clearly understand from which time position the representative screen has been extracted. Furthermore, by making the display size of the representative screen the same as the size of the frame of the frame, and displaying the representative screen in a form in which the representative screen is allocated to the frame of the frame corresponding to the time, it is possible to more intuitively understand. There is.

Also, for the frame temporally behind the representative screen, the frame of the frame is displayed as it is,
Because for the frames temporally located before and not to appear on the frame portion that overlaps the representative screen frames representative of the video, the position becomes clear that there is sterically representative picture, time course And the positional relationship between the representative screen is more easily understood.

Furthermore, when displaying a plurality of representative screens, instead of extracting the screens at random, in order to associate the screens with the camera operation, the screen when the camera operation is changed to another camera operation is displayed. By using the icon and displaying it in correspondence with the frame of the frame indicating the lapse of time, a screen corresponding to the camera operation can be attached to the icon. This makes it possible to display icons that are easier to see.

Also, by showing the speed, direction and type of camera operation in the moving image with reference to the virtual line corresponding to the frame of the fixed operation frame, the camera operation speed can be easily understood.
