Abstract

PURPOSE:To form a scene with less stereoscopic sense into a video image with much stereoscopic sense by fetching video information into a memory from a stereoscopic photograph or the like, segmenting part of left/right video information and outputting the result as left/right stereoscopic video signals. CONSTITUTION:A picture fetch device 3 fetches a photograph 1 for right eye and a photograph 2 for left eye, an A/D converter 4 converts them into a digital data, the picture for right eye is stored in a memory 5 and a picture for a left eye is stored in a memory 6. The memories 5, 6 have respectively X address buffers 7, 8 and Y address buffers 9, 10 and data from a display position control circuit 11 is fetched into X, Y address buffers 7-10 to segment video information partially and gives an output. Thus, an object such as a scene, a mountain, a building or landform unable to obtain stereoscopic sense by a general pickup method is obtained as a video image with full stereoscopic sense.

Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention is a three-dimensional visualization system that utilizes binocular parallax! ! The present invention relates to a three-dimensional image device that creates a three-dimensional image from two types of subjects.

(Summary of the Invention) The present invention captures video information into a memory using an image scanner or the like from left and right stereoscopic images 11 having stereoscopic information corresponding to binocular parallax, cuts out a part of the left and right video information, and then It is output as a stereoscopic video signal.

Further, the cutout position and size of the video information can be changed arbitrarily.

(Prior art) Conventionally, when shooting a video to create a three-dimensional effect of landscapes or large objects, it was necessary to shoot with the left and right camera angles, which correspond to the left and right eyes, significantly wider than the distance between the human eyes. Depending on how stereoscopic the subject is to be photographed, the spacing is wider than about 65ax, which is the distance between human clothes, and in some cases, it may even require several kHz.

(Problems to be Solved by the Invention) As mentioned above, in the past, there were actually quite a few limitations on how to take videos of mountains, buildings, and other objects with a 3D effect, such as wind and large objects, and it was difficult to obtain images with a 3D effect. was difficult. or,
It was impossible to even shoot aerial stereoscopic video images with a three-dimensional effect.

(Means for Solving the Problems) The stereoscopic imaging device of the present invention can display landscapes, mountains, buildings, topography, etc.
In order to photograph a subject with a three-dimensional effect that cannot be obtained with the in-shell shooting method, a two-eye camera that has binocular parallax information is used.
a video information capture device that captures video information from different kinds of subjects; a first storage device that stores one of the video information captured by the video information capture device; and another video information captured by the video information capture device. a second storage means for storing video information; a cutout output means for partially cutting out and outputting arbitrary video information from the first and second storage means; and stereoscopic video signal output means for outputting as a stereoscopic video signal.

The apparatus further includes a cutout control means for changing the position of the video information cut out by the cutout output means and for changing the cutout size of the video information cut out by the cutout output means.

(Function) That is, in the present invention, two photographs having stereoscopic information obtained from a stereoscopic photograph, an aerial photograph, etc. are partially stored in a memory using an image scanner or the like, respectively, and a part of the image information of each is cut out. At this time, by arbitrarily changing the cropping position and size, the displayed image looks like it was shot by burning, tilting, or zooming the subject.

For stereoscopic photography, there is no limit to increasing the distance between the left and right cameras, as there is with video cameras. Furthermore, it is generally well known that in aerial photography, it is possible to take stereoscopic photographs with a single camera.

(Example) Hereinafter, the present invention will be described in detail based on the example shown in the drawings.

FIG. 1 is a block diagram of a stereoscopic imaging device according to the present invention.

The image capturing device 3 captures a photograph 1 of the right medication and a photograph 2 of the left medication into the present device. As the image capture device 3, an image scanner or the like is used. The image signal captured by the image capturing device ra3 is A/[)
After being converted to digital data by converter 4,
The image of the right medication is stored in the memory 5, and the image of the left medication is stored in the memory 6. The memories 5 and 6 have sufficient capacity to store the captured photographic image without any deterioration. The memory 5 and the memory 6 have an X address buffer y7+8 and a Y address buffer 9, 10, respectively, and input data from the display position control circuit 11 to each X,
Any image data in the memory can be read by importing it into the Y address pan 777+8+9.10. That is, it is possible to partially cut out and output video information.

FIG. 2 shows the display position control circuit in detail.

The CPU 24 in the circuit loads the desired display start address into the X address counter 26 and the Y address counter 27 via the data bus 30 in accordance with the program stored in the ROM 25.

After that, the address counter values of the respective address counters 26 and 27 are monitored by the clock of the C○ (voltage controlled oscillator) 29, and when the desired display final address is reached, the display start address is loaded again and the count is repeated. do.

In addition, even if the display area in the memory is expanded or reduced, in order to display the same on the CRT monitor, an address counter must be set so that the desired display area in the memory can be displayed within one field period. It is necessary to change the tarokku to 26°27 according to the display area.

For this purpose, the CPU 24 sends the control voltage data of the VCO 29 to the D/A converter 28 via the data bus 30, converts it into an analog voltage, and inputs it to the VC029.

FIG. 3 shows a flowchart regarding display area control.

The contents of the memory read in this way are stored in the D/A in FIG.
It is output as a video signal by converters 12.13. Each video 43 is input to a CRT 15.16. A polarizing plate 17.18 is pasted on the screen of each CRT 15.16, making it a half mirror.
Images displayed on the CRTs 15 and 16 can be superimposed and viewed stereoscopically using the polarized glasses 20.

Further, the output from the D/A humbator 12, 13 is input to the switching circuit 14, and by switching between the right eye image and the left eye image for each field, a time-division stereoscopic video signal is output.

The time-division stereoscopic video signal thus created is input to the CRT 21, and is also input to the 7gupter 22 which drives liquid crystal shutter glasses that open and close in synchronization with this signal.

This allows stereoscopic viewing using the liquid crystal shutter glasses 23.

In FIG. 4, (a) and (b) are images for the right eye and the left eye that have been imported into the memory within this device. Assuming that the desired display area is the area 38 and 39 surrounded by broken lines on the left and right sides, the images of the right limit and left dose become as shown in FIGS. (C) and (d) by the above-mentioned display position control.

Similarly, the display area in memory is 4 (1, 4) surrounded by a broken line.
1, the images of the right and left doses are (e), respectively.
The result will be as shown in the figure and (f).

(Effects of the Invention) According to the present invention, scenes that have a difficult three-dimensional effect, such as large buildings, mountains, and undulating terrain, may look grand even when viewed with human clothes, but have little three-dimensional effect. can be provided as a three-dimensional image. In addition, conventionally, it was very difficult to take a stereoscopic aerial image with a three-dimensional effect because it required many controls, but according to the present invention, it is possible to capture an aerial stereoscopic image with a three-dimensional effect by using a video camera. The same effect can be obtained.

Furthermore, such images can be made to look as if they were shot with a video camera using the four methods of zooming, burning, tilting, etc., thereby expanding the expressive range of video works.
