Abstract

PROBLEM TO BE SOLVED: To simply editing of a video signal with high image quality in a short time by outputting an original video image onto a final medium, based on position information of the video signals in the order of registration on an edit table. SOLUTION: A compression video means 5 generates a video image, resulting from compressing an original video image 1 (e.g. a compressed video image or a video image that is compressed after interleaving a frame) and extracts position information (number such as a time code) of a frame of the original video image 1 and adds the information to the video image after the compression. Thus, the video image after the compression is edited, and its number (position information, time code) is registered in an edit table 6, the original video image 1 with high image quality is received based on the number (position information, time code) registered in the edit table 6 and outputted as a final video image 9 onto a tape or a DVD-RAM or the like. An edit means 7 displays and edits the video image after the compression. An edit execution means 8 reproduces the original video image 1 with high image quality, based on the number registered in the edit table 6 and outputs it as the final video image 9 onto the tape or the DVD-RAM or the like.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments and operations of the present invention will be sequentially described in detail with reference to FIGS.

FIG. 1 shows a system configuration diagram of the present invention.
In FIG. 1, an original video 1 is a high-quality original video reproduced from a tape or the like, and is a high-quality video reproduced from one or a plurality of tapes.

The personal computer 2 captures and edits the original video 1 and outputs the final video 9. Here, the capture board 3, the compression means 5, the editing table 6, the editing means 7, the editing executing means 8, etc. It is composed of
The personal computer 2 uses a recording medium (not shown) (for example, a CD-R).
OM), a program read from a hard disk device as an external storage device, or a program downloaded from an external storage device of the center via a line or a LAN, is loaded into the main storage and started up, and will be described below. Various processes are performed.

The capture board 3 is a high-quality original video 1
And a so-called board (input / output terminal such as PCI / I connected to an external connection terminal of the personal computer 2).
The board is connected to the SA terminal and takes in the video signal from the outside. Note that, in the capture board 3 according to the present invention, the time code is captured together for each frame included in the video signal, and the time code is output together with the original video 1 or separately in synchronization.

The uncompressed image 4 is an uncompressed original high-quality image (original image 1) captured by the capture board 3. The compressed video means 5 generates a video (for example, a compressed video or a video compressed after thinning out frames) of the original video 1 and extracts position information (a number, for example, a time code) of a frame of the original video 1. Is added to the compressed video. Thereby, editing is performed using the compressed video, the number (position information, time code) is registered in the editing table 6, and the editing table 6
The high-quality original video 1 is taken in based on the numbers (position information, time code) registered in, and output as the final video 9,
It is possible to record on a tape, DVD-RAM, or the like.

The editing means 7 displays the compressed video and performs editing (editing such as determining the order of the video and registering it in the editing table 6). Editing means 8
Is to output the corresponding high-quality original video 1 as the final video 9 reproduced based on the number (position information, time code) registered in the editing table 6 and record it on a tape, DVD-RAM, or the like. .

The final video 9 is a video obtained by reproducing the high-quality original video 1 based on the order (position information, time code) registered in the editing table 6, and is a tape or DVD-Video.
This is a high-quality edited video recorded in the RAM. The details will be sequentially described below.

FIG. 2 is a flowchart showing a compression procedure according to the present invention. This is a procedure when the compressed video means 5 in FIG. 1 takes in the original video 1 and compresses (compresses after thinning out).

In FIG. 2, S1 captures the original video 1. In this method, a high-quality original video 1 is reproduced from a tape or the like, and is captured by the compressed video means 5 via the capture board 3 shown in FIG.

In step S2, thinning is performed. That is, the amount of information is reduced and compressed by thinning out the high-quality original video 1 captured in S1, for example, about 60 frames (about 60 frames per second) in the case of the NTSC system for each frame. For example, thinning-out is performed as shown in FIG. 3B from the original video 1 in FIG.

In step S3, video compression and time code are added. In this case, after thinning out in S2, compression is performed for each frame (for example, JPEG compression), the time code of the original video 1 is added, and information for association with the frame of the original video 1 is added. For example, compression and a time code are added as shown in a compressed video of FIG.

In step S4, the data is stored in the hard disk. This means that the original video 1 is captured in S1, S2, and S3 and thinned out.
The compressed video to which the compression and the time code have been added is stored in a hard disk device capable of random access.

In S5, it is determined whether or not the processing is finished. In the case of YES, the compression process ends. In the case of NO, the process returns to S1 and repeats S2 and subsequent steps for the next original video 1. As described above, the original video 1 is decimated, compressed, and time-coded, the compressed video with a small amount of information is stored in the external storage device that can be randomly accessed, and a series of compression processing is completed. Thereafter, the compressed video is displayed and edited, and the time code (order) of the video is set in the editing table 6.

Editing work can be performed with a low information amount of 1/100.

FIG. 3 shows a conceptual diagram of the compression procedure of the present invention.
FIG. 3A shows an example of the original video 1. As shown in the figure, this high-quality original video 1 has a time code (a unique code assigned to each frame) at the head of each frame.
Is added. Here, the time code is information uniquely assigned to each frame such as the recording date and time of the video and the total storage amount of the video.

FIG. 3B shows an example of thinning. Here, a state in which the original video 1 of FIG. 3A is thinned out for each frame is shown. As a result, when the original video 1 is 60 frames / sec, it is 30 frames / sec, and the amount of information is reduced to half of the low information amount. If the number of thinnings is further increased, the amount of information can be further reduced.

FIG. 3C shows a state in which each frame of the video after the thinning of FIG. 3B is compressed. For example, J
The data is compressed from a fraction to several tens by the PEG method. At this time, a time stamp is added at the beginning as shown in the figure to store the correspondence between the position and the original video.

As described above, the high-quality original video 1 shown in FIG. 3A is thinned out and further compressed to reduce the amount of information to a low-information-amount video (compressed video, compressed video), and the time of the frame of the original video 1 is reduced. The code can be added to the compressed video.

FIG. 10 shows another explanatory view of the present invention. FIG. 10A shows a flowchart. This flowchart shows a procedure for performing a predetermined process (for example, overlap, wipe, etc.) on a transition portion when switching from one video to another video when the final video 9 described above is recorded on a tape.

In FIG. 10A, step S51 captures images before and after the transition portion. In step S52, the data is stored in the hard disk. In steps S51 and S52, the original video before and after the transition portion of the high-quality original video 1 from a tape or the like is stored in the hard disk device.

In step S53, an image is created by applying a transition effect to the preceding and following images. In this case, a specified transition effect is exerted on the high-quality original video 1 stored on the hard disk in S52, and predetermined arithmetic processing is performed on the original video 1 so as to overlap, for example.

In step S54, recording is performed on the transition portion of the tape. That is, in S53, a video on which a transition effect is applied is created on the hard disk, and the created video is read out and recorded on a transition portion of the tape.

A step S55 decides whether or not the tone radiation has ended. If YES, the process ends. In the case of NO,
S51 and subsequent steps are repeated. As described above, FIG.
As shown in Edit Table 6, when a transition such as overlap or wipe is specified,
Before and after the transition portion at the boundary of the cut No., the high-quality original video 1 is stored in the hard disk, the arithmetic processing is performed on the original video 1 so as to produce the specified tone transition effect, and then recorded on the transition portion of the tape. Thus, it is possible to automatically add a transition effect based on the high-quality original video 1.

FIG. 10B shows an example of the editing table 6. The editing table 6 has a transition column at the right end column. Here, a designated transition effect (for example, overlap, wipe, etc.) is processed on the transition portion and then recorded on the tape transition portion.

FIG. 10C shows a video image after editing. Here, an overlap transition effect is performed between Cut 1 and Cut 2 and a wipe transition effect is performed between Cut 3 and Cut 4 (for example, not only at the boundary between Cut 1 and Cut 2 but also at the boundary). The processing is performed so that, for example, the image before and after the predetermined range is gradually changed from the image of cut 1 to the image of cut 2).

[0059]

As described above, according to the present invention,
An editing operation is performed by using a compressed video in which the original video 1 has a small amount of information, and the order is set in the editing table 6. Based on the editing table 6, necessary video is reproduced from the high-quality original video 1 and recorded. In addition, since the processing is performed so that the transition effect specified in the transition portion is generated, a simple configuration, short-time and high-quality video editing can be performed.
