くく疲れ易い、という問題点があった。However, in such a conventional stereoscopic TV apparatus, the binocular parallax to be displayed changes when the screen size is different even if the input stereoscopic image signals are the same. 6 (a) and 6 (b) show this.
(A) shows a small display surface with binocular parallax of Δs, and (b) shows a large display surface with binocular parallax enlarged to ΔL. If the binocular parallax has a too large value, there is a problem in that the observer is hard to see stereoscopically and is easily tired.

両眼立体視できなくなる。As shown in FIG. 7 (a), it is difficult for the observer to see stereoscopically when the binocular parallax ΔN is large and the position P of the 3D-expressed object is far away from the image display surface. The distance between the adjustment and the stereoscopic view is inconsistent.
It means that binocular stereoscopic vision becomes impossible. Further, as shown in FIG. 7B, the subject at the distance of ∞ is displayed exactly in the distance between the eyes of the observer in the stereoscopic image.
If the binocular parallax ΔF becomes larger than this, the observer cannot also perform binocular stereoscopic viewing.

化する。In recent years, in computer graphic terminals, the multi-synchronous type has become mainstream, and many of them are used by switching the screen resolution. For example, at low resolution, a screen of 640 x 400 pixels that is generally used in personal computers, and at high resolution, 2000 of a workstation.
The range of resolution (image frequency) is wide up to an image of about 1000 pixels. When these image signals are used by switching them using a single multi-synchronous display, the size of the screen is constant, so images with the same number of dots will have different sizes depending on the resolution of the image signal.

A small image is displayed in (d), and the binocular parallax Δs in (c) is larger than Δt. As a result, when a stereoscopic CG image or the like is displayed,
The displayed binocular parallax changes greatly depending on the image resolution, and in some cases, the observer may not be able to stereoscopically view binocularly and may easily get tired.

In addition, there are cases where the display system can change the size such as the window environment, and this also changes the size of the binocular parallax that is displayed, and in some cases it is difficult for the observer to see stereoscopically. It was easy to get tired.

視差ΔｘはFurther, the parallax calculator 8 calculates depth information (which is defined as a parallax map) at each point of the input image from the right image signal and the left image signal. Various methods for calculating a parallax map have been proposed, but here, a block matching method using correlation calculation will be described. In FIG. 2, consider left and right images of size N × M. Consider a block window of n × n pixels (3 × 3 pixels in the figure) in the left image. The same image as this block window is searched for in the right image using a window of the same size, and the horizontal component Δx of the vector (Δx, Δy) indicating the displacement of the left and right block positions at this time is the center coordinate of the block window. It becomes the binocular parallax of the left and right images. If the position of the block window of the reference left image is translated over the entire screen and the position of the corresponding block (binocular parallax) of the right image is obtained in all cases, the parallax map of the entire screen (each screen What shows the depth distance at the place) is required. Here, the shift between the left and right images at the image coordinates (x, y), that is, the binocular parallax Δx is

When the binocular parallax value is positive, the right image is located on the right side and the left image is located on the left side with respect to the reference image. However, the depth side of the binocular parallax 0 is shown, and when the value of the binocular parallax is negative, it means that the subject exists on the front side of the depth position of the binocular parallax 0.

At this time, rather than simply extracting the maximum value of binocular parallax, spatially low-pass filtering may be performed, or multiple extraction regions may be prepared and calculated by a statistical method from these.

The basic operation is the same as that of the first embodiment, but since the left and right images are time-division stereoscopic images that are alternately input in time as shown in FIG. 4,
A process corresponding to this is required. At this time, the liquid crystal shutter switching pulse generator 17 outputs the liquid crystal shutter control signal shown in FIG. 4, and the liquid crystal shutter glasses 18 cause the right eye shutter to block the light when the left eye shutter transmits the light. , And vice versa when the right-eye shutter is transparent.

Detects the horizontal and vertical frequencies of the input image signal and determines the resolution of the input image. The basic synchronization timing generation unit 11 outputs synchronization timing data that matches the horizontal and vertical frequencies of the input image, and the synchronization unit 12 synchronizes with the timing of the image signal. Further, the parallax calculation unit 8 calculates a parallax map of the input image from the right image signal and the left image signal that are alternately input with respect to time. The parallax map calculation method can be calculated in exactly the same way as in the first embodiment.

It is also possible to prepare a plurality of extraction regions and calculate from these by a statistical method.

のを基本にして適宜量を調節してもよい。Next, the proper parallax determination unit 10 displays a stereoscopic image based on the output of the resolution determination unit 9 and the display size of the image, the output of the parallax calculation unit 8 and the distance information between the observer and the display surface. Determines the amount of parallel movement of the left and right images to enable binocular fusion. The method of determining this is also exactly the same as in the first embodiment. That is, the maximum binocular parallax of the output of the parallax calculation unit 8 is Δ (dots), the number of horizontal dots of the input image signal output from the resolution determination unit 9 is DH, the horizontal length of the display CRTs 1 and 2 is L, and the visual distance measurement is performed. The viewing distance of the observer measured by the unit 16 is ds, and the maximum parallax Dm on the screen is (Equation 3)
Therefore, when the maximum value of the binocular parallax is set to be the binocular parallel condition of the observer, the parallel movement amount Dc is represented by (Equation 4). However, the determination of Dc may be appropriately adjusted on the basis of the one derived by this equation.

Based on, the parallax control unit 13 translates the left and right images in the opposite directions by Dc / 2. At this time, since the left and right image signals are time-division stereoscopic image signals, the left and right images are alternately switched. Therefore, the parallel movement amount of the image is switched between + Dc / 2 and -Dc / 2 for each field. Then, the RGB separation unit 14 decomposes the image signal into RGB signals, and outputs the RGB signals to the CRT 1 via the CRT drive unit 15. The left and right stereoscopic images displayed by the CRT 1 are independently presented to the left and right eyes of the observer 7 wearing the liquid crystal shutter.

る。The operation of the stereoscopic TV apparatus of the present embodiment configured as above will be described. In the first and second embodiments, the size of the image display is unique to the size of the display device itself even if the synchronizing frequency of the input video signal is different. In the present embodiment, a plurality of stereoscopic images are displayed in a window environment on a recent mainstream computer screen. Further, the parallax is controlled in response to the situation where the observer changes the size of the display window by operating the mouse. It is assumed that the CRT 1 and CRT 2 in FIG. 8 have a plurality of display windows on the same screen, and one of the windows displays a stereoscopic image.
