Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image display capable of simultaneously displaying time information of a displayed image when reproducing and displaying a series of images such as images taken by a VTR camera. Regarding the device.

[0002]

2. Description of the Related Art With the development of signal processing technology and device technology, the digitization of video equipment that handles moving images is rapidly progressing. With regard to video recording, the progress of digital compression technology has made it possible to record video signals on a recording medium such as a hard disk or a magneto-optical disk, and an editing system using them has been developed. From the past,
In a linear editing system using a VTR, fast-forwarding and rewinding had to be carried out at the time of editing in order to confirm an image, whereas in an editing device using a hard disk, a magneto-optical disk, etc. Since the recorded data can be randomly accessed, the editing time is shortened and the workability is improved.

In such an editing apparatus, it is important for the workability to immediately and intuitively know the position information of the reproduced image. In other words, for example, the position information and temporal information of the playback image such as which part of the image of the material is the currently selected image that is randomly selected and how many minutes later the image of the material continues If it is possible to intuitively know the information one by one, the efficiency of editing work is improved.

Heretofore, the image display device used in such an editing device has been a display device as shown in FIG. FIG. 8 is a diagram showing an apparatus for displaying a reproduced image,
The monitor 80 has an image display section 81 and a time display slider 82.
Is provided, and the temporal position of the image displayed on the image display unit 81 is known from the position of an instruction unit (hereinafter referred to as a slide cursor) 83 that moves in the time display slider 82 and notifies the position. be able to. That is, the left end of the time display slider 82 represents the start point of the series of material images, the right end of the time display slider 82 represents the end point of the series of material images, and in the meantime, the position is proportional to the position of the slider.

[0005]

However, in the above-described time information display, there is a problem that it is difficult to search for a target image at the time of editing. In other words, with the method of displaying time information described above, it was not possible to intuitively grasp the absolute time of the recorded image data. The relative position of the display image in the total recording time can be grasped by the slider, but since the total recording time of the material image is expressed by the slider of a predetermined length set in advance, the time of I couldn't know where the image was.

For this reason, although the VTR data photographed during data gathering usually has a time code recorded, it was not possible to search for an image using the time code and reproduce / display it. Further, for data that is not managed by time code or image data that is difficult to manage by time code, it is more difficult to search for a target image, and there is a demand for knowing the time or position of a scene change.

Therefore, the object of the present invention is to intuitively grasp the time information of the displayed image both in the relative time and in the recorded real time (hereinafter sometimes referred to as absolute time). An object of the present invention is to provide an image display device that can be used.
Another object of the present invention is to provide an image display device capable of displaying a position where a time code is discontinuous or where a scene change occurs.

[0008]

In the above-mentioned display device, since the slider showing the time of the display image is normalized to a predetermined length, only the relative position can be displayed, which is intuitively real. It is difficult to grasp the time. Therefore, the sliders whose size fluctuates in proportion to the real time are displayed simultaneously. Then, the correspondence between the relative time and the real time is displayed between the slider and the original relative time slider.

Therefore, in the image display device of the present invention, the image display means for displaying the image data in the first area of the display device and the orthogonal image data provided in the second area of the image display means. In a relative time scale that normalizes the entire display period and an absolute time scale that indicates the real time associated with the image data, the temporal transition of the displayed image data is linearly displayed and is currently displayed. The relative time scale and the absolute time scale corresponding to the present image are displayed on the relative time scale and the absolute time scale.

Preferably, the time information display means assigns a predetermined section to a predetermined position of the absolute time scale even in a time zone in which there is no display image in the image data, and displays the image data in the display of the temporal transition. The discontinuity of is visually displayed.

Further preferably, the time information display means is
The position of the scene change of the series of image data is further displayed.

[0012] Specifically, the image display device of the present invention is a storage means for storing a series of image data in a randomly accessible manner, and an image for detecting time information of the series of image data stored in the storage means. The image data stored in the storage means is displayed on the display device by the image display means, and the time information of the image data detected by the image data management means is displayed as the time. The information is displayed on the display device by the information display means.

Further preferably, the image display device of the present invention is
By further specifying an arbitrary position on the relative time scale or the absolute time scale of the time information display means, the image information specifying means further specifies an image at an arbitrary relative time or an arbitrary real time in the image data.

[0014]

According to the image display device of the present invention, the image data is displayed on the display device, and the time information of the image data is displayed at a position where it can be viewed simultaneously with the displayed image. The display of the time information means that, in the area defined by the scale orthogonal to the relative time indicating the time in the entire period of the image data to be displayed and the real time of the image data to be displayed, The time transition is displayed as a line. Further, the relative time of the currently displayed image is specified on the relative time scale, and the absolute time of the currently displayed image is specified on the absolute time scale. Therefore, it is possible to grasp the time information of the display image. In addition, when the image is not continuous and is flying, the line showing the temporal transition is not a straight line, so that such a state can be grasped.

[0019] Such an AV server device 90, for example,
Monitor 5 of the image editing apparatus 50 that is used by being connected to
An image display method in 5 will be described with reference to FIGS. 3 and 4. FIG. 3 shows the monitor 5 of the image editing apparatus 50.
It is a figure which shows the display screen of No. 5. As shown in FIG. 3, the screen 1 of the monitor 55 is provided with a multi-window environment by the X window system, for example, and an image display window 2 for displaying a moving image input via the video interface 54 and an image display. A time information display window 10 for displaying time information of the image displayed in the window 2 is open. Mouse cursor 40
Is a cursor that the editor moves by operating a mouse (not shown). With the mouse cursor 40, an arbitrary position on the screen 1 can be selected.

Next, the time information display window 10 will be described. The time information display window 10 informs an editor who is viewing the image displayed in the image display window 2 of the time information of the displayed image, and
On the contrary, this window allows the editor to specify the time and select the image to be displayed. The structure of the time information display window 10 is shown in FIG. FIG. 4 is a diagram showing an example of the time information display window 10. FIG. 4A is a diagram showing the time information display window 10 when displaying image data that has been recorded for a long time, and FIG. It is a figure which shows the time information display window 10 at the time of displaying the image data currently displayed.

The time information display window 10 is provided with a relative time display slider 20 in the horizontal direction and an absolute time display slider 30 in the vertical direction. The relative time display slider 20 and the absolute time display slider 30 are respectively shown on the vertical axis. , A line showing the correspondence between the relative time and the absolute time is displayed in the area of the horizontal axis.

The sliders used as the relative time display slider 20 and the absolute time display slider 30 dynamically display / set variable values such as an audio slide volume in the X window system. This is an object that can be moved, and the position of the slide cursor in the slider moves to indicate the variable value, and a predetermined variable value can be designated by moving the position of the slide cursor with the mouse.

The relative time display slider 20 is a slider showing the relative time of the display image with respect to the total recording time of a series of moving images to be reproduced. That is, the left end of the relative time display slider 20 is the start point (0
%), The right end of the relative time display slider 20 indicates the end point (100%) of a series of moving images to be reproduced, and the slide cursor 21 existing at any position between them indicates the entire displayed image. The relative time in the recording time is shown.
The length of the relative time display slider 20 is displayed as a predetermined length regardless of the recording time of a series of moving images to be reproduced.

On the other hand, the absolute time display slider 30 is a slider that indicates the temporal position of the display image using the absolute time as an index. That is, the upper end of the absolute time display slider 30 indicates a recording start time T1 of a series of reproduced moving images, and the lower end of the absolute time display slider 30 indicates a recording end time T2 of a reproduced moving image. 1 second = 1
A predetermined time is indicated by a predetermined number of pixels such as 0 pixel.

If the image recording data has a time code, this time code is used as the absolute time. Therefore, the absolute time display slider 30 has a length corresponding to the recording time of a series of moving images to be reproduced. That is, when the recording time is long, the length of the absolute time display slider 30 becomes long as shown in FIG. 4 (A), and when the recording time is short, as shown in FIG. The length of the display slider 30 is shortened.

The relative time display slider 20 is plotted on the horizontal axis,
In the area with the absolute time display slider 30 as the vertical axis, the operation straight line 14 showing the relationship between the relative time and the absolute time of a series of moving images to be reproduced, and the association between the relative time display slider 20 and the absolute time display slider 30 are shown. Corresponding lines 24 and 34 are drawn. The motion line 14 is, in the example of FIG.
It is drawn so as to connect the point (0%, T1) and the point (100%, T2). Corresponding lines are drawn vertically and horizontally from the slide cursor 21 of the relative time display slider 20 and the slide cursor 31 of the absolute time display slider 30 to the operation straight line.

In the time information display window 10, for example, when one image in a series of moving images is displayed as a still image in the image display window 2, the relative time display slider 20 displays the displayed image. The position relative to the entire recorded image is shown, and the absolute time display slider 30 shows a position based on the absolute recording time of the displayed image. Slide cursors 21 and 3 of these sliders
Corresponding line 2 drawn from 1 vertically or horizontally to the motion line
4, 34 coincide with each other on the movement straight line 14.

When a moving image is displayed in the image display window 2, the slide cursor 21 of the relative time display slider 20 sequentially moves to the right as the image reproduction progresses, and the absolute time display slider 30 The slide cursor 31 moves in the downward direction. Also in this case,
Corresponding lines 24 and 34 from each slide cursor coincide with each other on the motion straight line 14.

Further, the mouse cursor 40 is moved to the slide cursor 21 of the relative time display slider 20 or the slide cursor 31 of the absolute time display slider 30 with a mouse (not shown), the mouse button is clicked, and then the mouse is moved. The slide cursor can be moved by moving it. In this case, when either one of the slide cursor 21 or the slide cursor 31 is slid, the other slide cursors move in a coordinated manner. Then, according to the position of the moved slide cursor, the image corresponding to the position is displayed in the image display window 2.

As described above, according to the image editing apparatus to which the image display apparatus of the present invention is applied, when displaying a series of moving images which are source images, the relative time in all recorded data and Both the absolute time and the absolute time based on the recorded time are displayed at the same time, and further, the slide cursors of the sliders move together with the progress of image reproduction. Therefore, the time information of the image being reproduced can be intuitively grasped.

When the display image is designated by the time information display window 10, it is possible to display arbitrary image data by designating by any time. That is, the relative time display slider 20
When designating a display image using, it is possible to give a relative instruction such as about the middle of the whole or about 1/4. Further, when the display image is designated using the absolute time display slider 30, for example, an intuitive instruction in accordance with the real time such as an image after a few minutes from the beginning of the image or an image after what frame is given. be able to.

Therefore, by using this image display device, the material can be easily searched when editing the image, and the editing can be performed efficiently.

Second Embodiment A second embodiment of the present invention will be described with reference to FIG.
The image display apparatus according to the second embodiment can properly display the time information of the recorded image data even for the image data whose shooting time is not continuous, that is, the images with discontinuous time codes.

For example, when shooting is carried out for 30 minutes, shooting for 10 minutes is interrupted, and shooting is carried out again for 10 minutes, in the time information display window 10 of the first embodiment, 4 recorded
In order to be able to specify the position within 0 minutes, for example,
As shown in (A), the absolute time display slider 30 having a length corresponding to 40 minutes is displayed. However, in this method, the position of the 10-minute shooting interruption cannot be known from the information in the time information display window 10. Therefore,
It is the image display device of the second embodiment that can display the continuity of the time code, and the time information display window 10 shown in FIG.

In the second embodiment, the structure of the time information display window is the same as that of the first embodiment, but the absolute time allocation method of the absolute time display slider 30 is different from that of the first embodiment. That is, the upper end of the absolute time display slider 30 indicates a recording start time T1 of a series of moving images recorded, and the lower end of the absolute time display slider 30 indicates a recording end time T2 of a series of recorded moving images, and during that period. Absolute continuous time is allocated regardless of the record. That is, in the above-mentioned example, the absolute time display slider 3 having a length corresponding to 50 minutes including a 10-minute shooting interruption portion
0 is displayed.

As shown in FIG. 5, in the image display device according to the second embodiment, even when the time code jumps in the absolute time display slider 30 and there is no image, a predetermined section is assigned, and therefore the operation of that part is performed. The straight line is represented as a vertical straight line parallel to the absolute time display slider 30 after only the absolute time has passed. By displaying in this way, it becomes easier to search for the target material or the material to be reproduced.

In the example shown in FIG. 5, the absolute time display slider 30 is secured at the position where the time code jumps for a length corresponding to the time.
However, in the discontinuous portion, it is not necessary to faithfully set the length of the section of the absolute time display slider 30 to be proportional to the flying time. For example, even if it is expressed by a predetermined length, or For example, a mark such as a wavy line may be used to merely indicate that the time code has skipped.

Third Embodiment A third embodiment of the present invention will be described with reference to FIG. The image display device of the third embodiment is configured to further display the position of the scene change in the time information display window 10 of the first embodiment. The display example is shown in FIG. In FIG.
The structure of the time information display window 10 is the same as that of the first embodiment, but marks 16a and 16b are added on the operation straight line 14. The positions of the marks 16a and 16b are positions where the scene changes in the series of moving image data being reproduced.

The position of this scene change can be obtained by various methods. For example, it may be a position where the time code is discontinuous, a position where a time stamp signal is added by the photographer at the time of shooting, or a position of a scene change detected by obtaining a motion vector of a series of moving images. This position may be detected by any suitable method according to each reproducing device and editing device.

In this way, the time information display window 10
By making it possible to display the position of the scene change,
It will be easier to search for the desired image.

The image display apparatus of the present invention is not limited to the above-described first to third embodiments, but various modifications can be made. For example, the above-described embodiment opens the time information display window and displays the time information under the multi-window environment of the X window system of the general workstation. However, another computer system or window system may be used, a dedicated display device may be used, or an image processing system for a specific purpose may be used.

Further, in the present embodiment, the image editing apparatus is
Although the configuration is connected to the AV server device whose configuration is illustrated in FIG. 2 and receives the supply of the video data, the configuration is not limited to this. Even if the external video interface 60 is connected to a normal VTR device and the video signal is supplied from the VTR device, there is no problem in using.

Also, various modifications may be made to the screen configuration of the time information display window. For example, the relative time display slider may be arranged vertically and the absolute time display slider may be arranged horizontally. Also,
Attributes such as shape and color of objects such as sliders are
It can be anything. For example, as shown in FIG. 7A, a so-called scroll bar 70 may be used, and in order to move the elevator 71 of the scroll bar 70 frame by frame, an up arrow 72a, a down arrow 72b, or the like is used. You may make it add a button object further.

Although the slider is not graduated in the above-mentioned embodiment, any graduation or the like may be provided so that the position of each slide cursor becomes clearer. Also, the position of the slider slide cursor,
That is, information indicating the time of the displayed image may be separately displayed at an arbitrary position in the time information display window. An example thereof is shown in FIG. In FIG. 7B, the value represented by the position of the slide cursor on the slider is separately digitally displayed as the relative time 23 and the absolute time 33 at the corners of the area where the motion straight line is displayed. With such a configuration, it is possible to intuitively grasp the time and check the exact time at the same time.

[0045]

According to the image display device of the present invention, since the time information of the displayed image is displayed in both the relative time and the recorded real time, it is displayed. The time information and the position information of the existing image can be intuitively grasped, and the search and the like can be easily performed, and the work efficiency is improved when the editing work is performed. Further, since the position where the time code is discontinuous or the position where the scene change occurs can be displayed, the necessary scene can be searched more easily, and the editing work can be performed more efficiently.
