DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD OF THE INVENTION

The technical field of claim 1 is NTSC
CCD using a CCD imaging device based on a television system
In the image pickup apparatus, the photosensitive surface of the CCD image pickup element is vertically divided into odd numbers (in the present invention, divided into 5 parts) at the manufacturing stage, and the divided parts (denoted as 1 to 5 Ch.) Are simultaneously scanned to output five video outputs. What constitutes a CCD imaging device.

The technical field of claim 2 is NTSC
In a display device capable of performing a plurality of scans (multi-scan) within one screen, such as a liquid crystal display device using a television system and a plasma display device, a 5-split NTSC-MST
The image taken by the imaging device is divided into 5 NTSC-MS
Ch. What connects and displays the numbers.

[0004] The technical field of the present invention relates to a disk type slow motion recording / reproducing apparatus, which comprises a
In the case of five pairs of video output from the MST type CCD image pickup device, a total of ten disk-type slow motion recording / reproducing devices, two for each output, a conversion switcher and an F.C. S. And a frame switcher capable of reproducing 150 frames of slow motion per second.

[0005]

2. Description of the Related Art In a conventional NTSC television system, when so-called virtual reality display (closed circuit television display in a venue) is performed, the number of frames per second is limited to 30. Although restricted, there was no solution as long as the NTSC television system was adopted.

In the case of slow-motion playback in so-called virtual reality display or broadcasting using the NTSC television system, in the conventional slow-motion playback device, the original image is recorded at 30 frames per second. Even if the magnification is increased, playback at more than 30 frames per second could not be performed, and slow-motion playback using digital methods enables slow-motion playback at more than 30 frames per second. Broadcasting in a system required a complicated converter.

[0007]

[Problems to be Solved by the Invention] A sports competition or the like is projected on a large television display device at a place other than the venue, and is shown to an audience.
When performing the so-called virtual reality display, in the conventional NTSC television system, the number of frames per second is limited to 30, and it is difficult to accurately display a fast-moving subject.

[0008] Also, when performing slow motion recording and playback in a virtual reality venue or television broadcast,
In the conventional NTSC television system, the number of frames per second is 3
Since it is limited to 0, no matter how slow the slow motion playback is, it cannot exceed the fineness of 30 frames per second.

The present invention enables the display of virtual reality at 150 frames per second and the recording and reproduction of slow motion.

[0010] The present invention enables the expression of the number of frames per second five times that of the NTSC television system at the virtual reality venue, and the slow speed that is five times that of the slow recording and playback of the NTSC television system during slow recording and playback. In addition, the video captured by the five-division NTSC-MST system is converted to the NTSC television system via an NTSC-MST / NTSC converter, so that compatibility for use in NTSC television broadcasting is provided.

[0011]

In a CCD image pickup apparatus in the NTSC television system, one screen is composed of 525 horizontal scanning lines, but is divided into five NTSC-MSTs.
In the case of a television, one channel shares 105 lines from 525/5 = 105.

Also, one CCD image pickup device has five pairs of video outputs, but one pair of outputs includes the output necessary for a color image.

In the present invention, the five pairs of video outputs are connected to a five-part NTSC-MST display device or a slow-motion recording device by five pairs of cables.
In the ST television camera image pickup device, it is also possible to combine them into one cable by a multiplexing device and send it to a video display device or a relay video sub-adjustment.

The multi-scan video display apparatus divides one screen into five equal parts in the vertical direction, and shares 105 horizontal scanning lines per channel and simultaneously scans five channels. Since the image of the piece can be displayed, it is possible to provide a realistic display with the image of the fast-moving sport.

[0015] In the imaging apparatus, a five-division NTSC-MS
The shooting sensitivity is reduced to one-fifth in the T television, but the display device can obtain five times the brightness.

As a display device, a CRT display device cannot perform multi-scan, and is limited to a display device capable of multi-scan such as a liquid crystal display device and a plasma display device.

The five pairs of video outputs from the 5-split NTSC-MST television image pickup device enable the disk-type slow-motion recording / reproducing device to reproduce slow motion five times faster than the current NTSC television-based slow-motion reproducing device.

The five pairs of video outputs from the NTSC-MST image pickup device are connected to a total of ten disk-type slow-motion recording / reproducing devices. S. And 5 times slow motion reproduction via a frame switcher.
