[Summary of the invention]

The present invention relates to a special effects device, and relates to a frame or field number accompanying a reproduced video signal from a video reproduction device and a frame or field number selected corresponding to the frame or field number.
The special effect processing control data from the special effect processing control data generating means is stored in the storage means, the reproduced video signal from the video signal reproducing device is supplied to the special effects processing device, and the data is transmitted from the storage means to the video reproducing device. By reading the special effect processing control data corresponding to the frame or field number attached to the reproduced video signal and supplying it to the special effects processing device, a series of data to be applied to a series of reproduced video signals from the video reproduction device can be read out and supplied to the special effects processing device. The special effect processing can be easily and quickly set, and the series of special effect processing applied to the reproduced video signal can be easily and repeatedly reproduced.

[Conventional technology]

Conventionally, for example, as disclosed in Japanese Utility Model Application Publication No. 53-20515, a plurality of monitor receivers, each equipped with a CRT (cathode ray tube), are arranged based on their respective screens (hereinafter referred to as small screens). A multi-screen video display device has been proposed in which video images are displayed on a single screen (hereinafter referred to as a large screen).

Such multi-screen video display devices display one video on a large screen, or display multiple screens each consisting of an array of multiple small screens (referred to as medium screens), each of which is smaller than the individual small screens or the large screen. In some cases, the same video may be displayed on each screen.

Further, in such a multi-screen video display device, the video is subjected to special effect processing and displayed on a large, medium or small screen respectively.

In this case, for example, special effect processing (including processing for display on a large screen, medium screen, or small screen as described above) is performed by applying multiple types of special effects to multiple locations of a series of reproduced video signals from a video playback device. In order to repeatedly display the video signal that has been subjected to this special effect processing on a large screen, the following method has been adopted. That is, first, a section where a reproduced video signal from a video reproduction device is supplied to a plurality of monitor receivers through a special effects processing device, and special effects processing is applied to the reproduced video signal while displaying it on a large screen. In addition to deciding on the type of special effect, use a stomp watch to measure the starting point of the video signal where special effect processing is to be performed, the elapsed time from then, and the waiting time until the next special effect processing is applied. Based on these, a special effect processing program is created using a microcomputer, and the program is stored in an auxiliary storage device. Then, the microcomputer supplies the played video signal from the video playback device to the special effects processing device, and supplies special effect processing control data to the special effects processing device according to the program read from the above-mentioned auxiliary storage device. The selection of the type of special effect and the point in time of the video signal at which special effect processing is to be performed are controlled.
