Abstract

PURPOSE:To obtain a large stereo color screen which gives a feeling of stereoscopic view simply by a video input for the number of stereo constitution sheets and a control signal. CONSTITUTION:This device is constituted in such a way that an optical system 4 corresponds to each CRT1 and the central point of an image is generated in the center of stereo picture. Synchronized video inputs 6, 6' and 6'' inputted to each CRT are, for example, consisted of three-layered screen. Delay quantities of variable delay circuits 7, 7' and 7'' are controlled by a computer 8, and a picture is synthesized by a picture synthesizer 10 through sampling signal generators 9, 9' and 9''. It is assumed that the place from a point 11 to a point 12 on a screen of the CRT1 is a background, and a point 14 is installed from a foreground point 13. When images 13 and 14 are moved backward of the figure, and images 13'' and 14'' are shifted to upward of the picture, stereo images 13''' and 14''' move in the protruding direction, and vice versa. Positions of respective images on image display elements are controlled in accordance with positions and actions, and backward images of overlapped parts on respective images are eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a stereoscopic television apparatus capable of displaying (4+) large-area stereoscopic images.

Conventional chestnut composition and its problems Traditionally, the method of achieving stereoscopic vision was the so-called Lippmann integral photography, in which a fly's eye lens was placed on a photographic plate. However, this is a still image and cannot be a moving image. Chii = cheap, realization (l, 1, not'l
'11i1 thing/ko○ Also, I used two songs that looked at the TV screen with the left and right eyes, and the polarizing filters that were orthogonal to each other were combined, and the image 11+i was combined orthogonally to each other. :(The story of how to see while wearing glasses.) However, this had the trouble of requiring the viewer to wear all the glasses.

OBJECT OF THE INVENTION The objective of the invention is to provide a three-dimensional camera that can display a large three-dimensional image of a cup without using glasses.

The purpose of this project is to provide a

Structure of the Invention In the present invention, a large number of image displays 7,

An optical system corresponding to the image display element is provided so as to connect the 11° point or the 11° point of each image display element to a point at a distance of ->j, and the image source is a composite of multiple images, The present invention is characterized in that the position of each image on each image display element is controlled according to the position and movement of the image, and the image behind the overlapping portion on each image is erased.

DESCRIPTION OF THE EMBODIMENTS FIGS. 1 and 2 show I'f# diagrams of a stereoscopic television apparatus according to an embodiment of the present invention. 1 is a cathode ray tube (hereinafter abbreviated as CRT) in which a large number of air channels are arranged vertically and horizontally on a plane;
2 indicates the collecting surface of the image plane 03 f (i indicates the center position of the stereoscopic image. The optical system 4 corresponds to each CR'r1 and is configured so that the image of the center point is generated at the center position 3 of the stereoscopic image. The image size and linearity of each Cf (TI) are precisely adjusted.

Figure 3 is a block diagram of a processing circuit for video signals input to each CftT. .7' and 7'' are variable delay circuits whose delay amount is controlled by the computer 8. 9,
Reference numerals 91 and 917 denote sampling signal generators, which synthesize images in the image synthesizer 9 under the control of the computer 8.

A control signal to the computer 8 is applied to the input terminal 11 in synchronization with the video input.

Next, the relationship between images on a CRT and stereoscopic images will be described. Fourth
The figure is an explanatory diagram thereof. 1,1/,1LLr,J, three of the many CRTs are shown. 4.4/, 4'7 are optical systems corresponding to CRT1, 1', 1'', respectively.CR
The area from point 11 to point 12 on the screen of T1 is the background,
There (point 14 is Uj, slightly smaller than foreground point 13.

In the CRT 1', the background is from point 11' to point 12', and the foreground is from point 13'J to point 14'. , also on CRT1'', the background is point 11'' to point 12'/, the background is point 13
'', the point is 14''. Points 11, 11', 11''
An image of point 1 is generated at 11'' by each optical system.
2.12', 12'' image occurs at 12'''. Point 13.
If the image of 13', 13'' is 1 point 14.14', 14
The image of "0" occurs at 14", and this image occurs three-dimensionally at the front and rear positions and does not overlap depending on the viewing direction.

As is clear from the figure, 11.12=11', 12'-213'', 14''.

Now, if images 13 and 14 are moved downward in the figure and images 13'' and 14'' are moved upward in the figure, three-dimensional images 13/// , 14///

Also, images 13 and 14, image 13'% 14', and image 1sl+.

When both 14'' are moved upward in the figure, the three-dimensional images 13'' and 14'' are moved downward in the figure accordingly.This←4
, the amount of delay described above is determined by the position of each Cf (T 1.1', 1") and the relative position II value relationship of the optical system, and the amount of delay of each image is determined by a computer. 21-4.; 1-4 11-Effects of the invention As explained above, according to the present invention, the video manual and control system for the number of 4-layer videos can be used.

It can be used to display a large color 3D television screen.

In addition, when using elements such as liquid crystal color and ζ channel displays as image display elements, image distortion; /1-
Therefore, more accurate stereoscopic television images can be obtained.
