DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a three-dimensional TV device capable of displaying a three-dimensional image.

[0002]

2. Description of the Related Art A conventional three-dimensional image display apparatus is, for example, as shown in FIG. In this method, two CRTs, each of which has a display surface covered with orthogonal polarizing filters, are prepared and combined by a half mirror, and the observer wears glasses configured with the corresponding polarizing filters, and wears left and right glasses. This is for observing an image corresponding to the eye.

[0003]

However, in such a conventional stereoscopic TV device, even if the input stereoscopic image signal is the same, the displayed binocular disparity changes when the screen size is different. FIGS. 6A and 6B show this.
(A) is a small display surface where the binocular parallax is Δs, and (b) is a large display surface where the binocular parallax is expanded to ΔL. If the binocular parallax has an excessively large value, there is a problem that an observer is hardly stereoscopically viewed and easily fatigued.

As shown in FIG. 7 (a), it is difficult to perform stereoscopic viewing when the binocular parallax .DELTA.N is large and the position P of an object displayed in 3D is greatly separated from the image display surface. The distance between the adjustment and the stereoscopic view is inconsistent.
(Approaching) will be impossible to binocularly stereoscopically view. Also, as shown in FIG. 3B, the subject at the distance of ∞ is displayed at the distance between both eyes of the observer in the stereoscopic image.
If the binocular parallax ΔF becomes larger than this, the observer will also be unable to perform binocular stereoscopic viewing.

Recently, multi-synchronous computer graphic terminals are mainly used, and many of them are used by switching the screen resolution. For example, at a low resolution, a 640 × 400 pixel screen generally used in a personal computer, and at a high resolution, a workstation 2000
The range of resolution (image frequency) is wide up to an image of about × 1000 pixels. When these image signals are switched and used by using one multi-synchronous display, the size of the screen is constant. Therefore, an image having the same number of dots depends on the resolution of the image signal. Changes.

FIGS. 6 (c) and 6 (d) show this, in which (c) shows a case of a low-resolution image signal and (d) shows a case of a high-resolution image signal. In (d), a small image is displayed, and the binocular disparity Δs in (c) is larger than Δt. As a result, when a stereoscopic CG image or the like is displayed,
Depending on the resolution of the image, the displayed binocular parallax greatly changes, and in some cases, the observer may not be able to perform binocular stereopsis and may easily be tired.

[0007] The image signal currently being broadcast is HD.
TV, EDTV, and NTSC. These have different display sizes due to differences in screen aspect ratio and compression processing in addition to the screen resolution. In addition, the display method may be able to change the size like a window environment, which also changes the size of the displayed binocular parallax, and in some cases, makes it difficult for a viewer to perform binocular stereopsis. In some cases, he was easily tired.

The present invention solves the above-mentioned problem. Even when the same stereoscopic image signal is input, the amount of binocular parallax is automatically adjusted according to the size of a screen (window), so that a more natural stereoscopic image can be easily observed. The purpose is to enable visual observation.

[0009]

According to the present invention, there is provided a parallax calculating section for calculating binocular parallax from data of the size of an image display section and left and right images and calculating the maximum or minimum value thereof, A viewing distance measuring unit that measures the distance, a resolution determining unit that detects the synchronization frequency of the input image signal and determines the type of the input image signal, the size of the display screen, the output of the parallax calculating unit, and the viewing distance of the observer. Calculating the magnitude of the binocular parallax of the image displayed using the output of the resolution discriminating unit, and calculating the amount of parallax change to enter the binocular fusion range of the observer; It has a parallax control unit that horizontally translates the left and right images in accordance with the appropriate parallax determination unit, so that the displayed stereoscopic image falls within the binocular fusion range of the observer even when the synchronization frequency of the input video signal changes. Three-dimensional T characterized by controlling left and right images It is a device.

According to the present invention, with the above-described configuration, the binocular disparity of an image displayed using the viewing distance of the observer, the resolution (frequency) of the input image signal, the size of the display screen, and the output of the disparity calculating unit is obtained. Calculate the size, translate the left and right images horizontally so that this is within the binocular fusion range of the observer, and the displayed binocular disparity automatically enters the binocular fusion range of the observer Works.

[0011]

Embodiments of the present invention will be described below. FIG. 1 shows a configuration of a stereoscopic TV device according to the first embodiment of the present invention. In FIG. 1, 1 and 2 are CRTs, 3 and 4 are linear polarizers, 5 is a half mirror, 6 is glasses configured with a polarizing filter, 7 is an observer, 8 is a parallax calculator, 9 is a resolution determiner, 10 is an appropriate parallax determination unit, 11 is a basic synchronization timing generation unit, 12a,
b is a synchronization unit, 13a and b are parallax control units, and 14a and b are R
GB separation units, 15a and 15b are CRT driving units, and 16 is a viewing distance measurement unit.

The operation of the three-dimensional TV device thus constructed according to the present embodiment will be described. First, the right image signal is input to the resolution determination unit 9, the synchronization unit 12a, and the disparity calculation unit 8.
The resolution determining unit 9 detects the horizontal frequency and the vertical frequency of the input image signal and determines the resolution of the input image. The basic synchronization timing generation unit 11 outputs synchronization timing data corresponding to the detected horizontal and vertical frequencies of the input image to the synchronization unit 12ab, and the synchronization unit 12ab synchronizes with the input image signal and generates synchronization timing necessary for post-processing. Occurs.

Further, the parallax calculating unit 8 calculates depth information (defined as a parallax map) at each point of the input image from the right image signal and the left image signal. Although various methods of calculating a disparity map have been proposed, a block matching method using a correlation operation will be described here. 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 the block window is searched for in the right image using a window of the same size. At this time, the horizontal component Δx of the vector (Δx, Δy) indicating the shift of the left and right block positions is calculated at the center coordinates 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 across the entire screen and the position of the corresponding block of the right image (binocular disparity) is obtained in all cases, the disparity map of the entire screen (each image on the screen) Which indicates the depth distance at the place). Here, the shift between the left and right images at the coordinates (x, y) of the image, that is, the binocular parallax Δx is

[0014]

(Equation 1)

Here,

[0016]

(Equation 2)

## EQU1 ## Where Σ in (Equation 2) is n × n
In the block window, the coordinates xk and yk are changed to obtain the sum within the absolute value. Also, GR (xk, y
k) and GL (xk, yk) are the coordinates (x
k, yk).

Of the binocular parallaxes Δx and Δy, Δx directly indicates the depth position. When the value of the binocular parallax is positive, the right image is positioned on the right side and the left image is positioned on the left side with respect to the reference image. However, when the value of the binocular disparity is negative, it indicates that the subject exists on the near side from the depth position of the binocular disparity 0.

The parallax calculating section 8 outputs, for example, the largest value (binocular parallax of the farthest object) among the parallax maps obtained as described above. At this time, instead of simply extracting the maximum value of the binocular disparity, low-pass filtering may be performed spatially, or a plurality of extraction regions are prepared and calculated from these by a statistical method. Is also good.

Next, the proper parallax determining unit 10 outputs the output of the resolution determining unit 9 (result of determining the resolution and aspect ratio of the image by determining the type of the detected input image signal) and the display size of the image (in this case, Is the number of inches of CRT) and
Based on the output (parallax map) of the parallax calculating unit 8 and the distance information between the observer and the display surface by the parallax measuring unit 16, the stereoscopic image displayed by the observer of this stereoscopic TV can be fused with both eyes. The amount of translation of the left and right images is determined.

The method of determining this will now be described in more detail. The maximum binocular disparity of the output of the disparity calculating unit 8 is Δ
(Dots), the number of horizontal dots of the input image signal output from the resolution determining unit 9 is DH, the horizontal length of the display CRTs 1 and 2 is L, and the viewing distance of the observer measured by the viewing distance measuring unit 16 is ds. , The maximum parallax Dm on the screen is

[0022]

(Equation 3)

## EQU1 ## The left and right images are translated in such a manner that the angle is substantially equal to the binocular parallel condition of the observer or smaller. For example, when the maximum value of the binocular disparity is set to the binocular parallel condition of the observer, the translation amount Dc
Is

[0024]

(Equation 4)

## EQU2 ## Here, We is the distance between the eyes of the observer, and in actuality, the left and right images are adjusted by moving in parallel in the horizontal opposite direction by Dc / 2. Where Dc
May be appropriately adjusted based on the value derived from this equation.

The parallel movement amount Dc obtained as described above
, The parallax control unit 13ab translates the left and right images by Dc / 2 in opposite directions. And RG
The image signal is decomposed into RGB signals by the B separation unit 14ab and output to the CRTs 1 and 2 via the CRT drive unit 15ab. The images displayed by the CRTs 1 and 2 are polarizing plates 3 and
4, the light becomes linearly polarized light orthogonal to each other,
The left and right images are respectively separated into right and left eyes by polarizing glasses 6 whose linear polarization directions are set in directions corresponding to the polarizing plates 3 and 4, and the viewer 7 stereoscopically views.

As described above, according to the present embodiment, the type of the input image signal is determined and the size of the display surface is calculated, so that the observer always has a natural binocular disparity. A stereoscopic image can be observed.

FIG. 3 shows a configuration diagram of a three-dimensional TV device according to a second embodiment of the present invention. In FIG. 3, 1 is a CRT, 18 is liquid crystal shutter glasses, 7 is an observer, 8 is a parallax calculating unit, 9 is a resolution determining unit, 10 is an appropriate parallax determining unit, 11 is a basic synchronization timing generating unit, and 12 is a synchronizing unit. , 13 is a parallax control unit, 14 is an RGB separation unit, 15 is a CRT drive unit, 16 is a viewing distance measurement unit, and 17 is a liquid crystal shutter switching pulse generation unit. This configuration corresponds to the stereoscopic TV device according to the first embodiment corresponding to a time-division stereoscopic image signal.

The operation of the three-dimensional TV device according to the present embodiment configured as described above will be described. 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 input alternately in time as shown in FIG.
Processing 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 allow the right eye shutter to block light when the left eye shutter transmits light. When the right eye shutter is transmitted, the reverse is true.

First, the right image signal is input to the resolution judging unit 9, the synchronizing unit 12, and the parallax calculating unit 8. Resolution determination unit 9
Detects the horizontal and vertical frequencies of the input image signal and determines the resolution of the input image. The basic synchronization timing generator 11 outputs synchronization timing data according to 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 in time. The method for calculating the disparity map can be calculated in exactly the same way as in the first embodiment.

Next, the parallax calculating section 8 outputs the binocular parallax of the farthest object among the binocular parallaxes at each point of the image obtained as described above, for example. At this time, a low-pass filtering process may be performed spatially in calculating the binocular disparity,
A plurality of extraction regions may be prepared, and a calculation may be made from these by a statistical method.

Next, the proper parallax determining unit 10 displays a stereoscopic image based on the output of the resolution determining unit 9 and the display size of the image, the output of the parallax calculating unit 8 and the distance information between the observer and the display surface. Determines the amount of translation of the left and right images to enable binocular fusion. The method of determining this is exactly the same as in the first embodiment. That is, the maximum binocular parallax output from the parallax calculating unit 8 is Δ (dot), the number of horizontal dots of the input image signal based on the output from the resolution determining unit 9 is DH, the horizontal length of the display CRT1, 2 is L, the visual distance measurement. The viewing distance of the observer measured by the unit 16 is ds, and the maximum parallax Dm on the screen is (Equation 3)
When the maximum value of the binocular parallax is set to be the binocular parallel condition of the observer, the translation amount Dc is expressed by (Equation 4). However, the amount of Dc may be appropriately adjusted based on the value derived from this equation.

The parallel movement amount Dc obtained as described above
, The parallax control unit 13 translates the left and right images by Dc / 2 in opposite directions, respectively. At this time, since the left and right image signals are time-division stereoscopic image signals, the left and right images are switched alternately. Therefore, the parallel movement amount of the image is switched as + Dc / 2, -Dc / 2 for each field. Then, the image signal is decomposed into RGB signals by the RGB separation unit 14 and output to the CRT 1 via the CRT driving unit 15. The left and right alternating stereoscopic images displayed by the CRT 1 are independently presented to the left and right eyes of the observer 7 equipped with the liquid crystal shutter.

As described above, according to the present embodiment, even when the input image signal is a time-division stereoscopic image signal, the observer can always observe a natural stereoscopic image displayed with appropriate binocular parallax. I can do it.

b is a synchronization unit, 13a and b are parallax control units, and 14a and b are R
The GB separation units, 15a and 15b are CRT driving units, and 16 is a viewing distance measurement unit. The above is the same as in the first embodiment.

The difference from the first embodiment is that the window information management unit 27 and the window information management control unit 2 are newly added.
6. Mouse state detector 25, window size detector 2
2. The point is that a window generation disappearance detection unit 23, a window focus change detection unit 24, and a mouse 28 are added.

The operation of the three-dimensional TV device according to the present embodiment configured as described above will be described. In the first embodiment and the second embodiment, the size of the display device itself is unique even if the synchronization frequency of the input video signal is different for the size for displaying an image. In the present embodiment, a plurality of stereoscopic images are displayed in a window environment on a recently mainstream computer screen. Also, the parallax is controlled in response to the situation where the size of the display window is changed by the mouse operation by the observer. It is assumed that a plurality of display windows exist on the same screen on the CRT1 and CRT2 in FIG. 8, and a stereoscopic image is displayed in one of the windows.

Normally, the observer can use the mouse 28 to change the size of the window as desired. If the size of the stereoscopic image changes correspondingly,
Since the binocular fusion range of the observer changes, it is necessary to constantly monitor the window size and always control the parallax accordingly. That is, the window information management control unit 26 detects information about the window by the mouse operation of the observer. The window information management control unit 26 manages the window currently displayed by the window creation / deletion detection unit 23, detects the size of each window by the window size detection unit 22, and outputs the size data of the corresponding window. Output to the appropriate parallax determination unit 10.

The appropriate parallax determining unit 10 obtains the number of vertical and horizontal dots on the display screen and the size of each window (the number of dots) based on the outputs of the resolution determining unit 9 and the window size detecting unit 22. Size (CRT
Is the actual size of the displayed window (inches, centimeters, etc.)
Is calculated. Subsequent processing is the same as in the first embodiment. That is, the parallax calculation unit 8 calculates depth information at each point of the input image from the right image signal and the left image signal, and outputs, for example, a maximum value or a minimum value.

Next, the appropriate parallax determination unit 10 outputs the output of the resolution determination unit 9 (result of determining the resolution and aspect ratio of the image by determining the type of the detected input image signal) and the display size of the entire image (this In the case, the number of inches of CRT)
The actual size of the display window is obtained from the size of the display window (the number of dots) output from the window information management unit 27 and the output of the parallax calculation unit 8 (parallax map) and observation by the parallax measurement unit 16. Based on the distance information between the viewer and the display surface, the amount of translation of the left and right images to enable binocular fusion of the stereoscopic image displayed by the viewer of the stereoscopic TV using (Equation 3) and (Equation 4) To determine.

Based on the amount of translation obtained as described above, the parallax control unit 13ab translates the left and right images by Dc / 2 in opposite directions. Then, the image signal is decomposed into RGB signals by the RGB separation unit 14ab,
A specified window in the display screen is passed through the window information management control unit 26 to the CR via the CRT driving unit 15ab.
Output to T1 and T2.

When the input image signal is displayed in a plurality of windows having different sizes, the above-described parallel movement amount may be calculated and applied independently for each window. Further, when a plurality of input image signals are displayed in windows having independent sizes, the processing may be similarly performed independently for each window.

Even when the observer changes the size of the window using the mouse 28, the window size detector 22 detects the change in the size of the window, and adjusts the amount of parallel movement of the left and right images corresponding to the change. The parallax determination unit 10 calculates immediately and reflects it on the display screen.

When displaying a plurality of stereoscopic images in a plurality of windows, only the window specified by the observer's mouse operation is used to specify the above-described camera parameter change by the mouse using the window focus change detection unit 24. Only the stereoscopic image displayed in this window is detected as the window that the observer is watching.
It is also possible to display an image contained in the binocular fusion range and measure the efficiency of the operation of the present invention.

As described above, even in a display system having a window environment in which the size changes, the size of each window is monitored by the window information management unit 27, so that the stereoscopic image displayed in the window is displayed. Within the fusion range of the observer.

In the first, second and third embodiments, the visual distance measuring unit 16 measures the visual distances of a plurality of observers, and calculates the average value, the weighted average value of each visual distance, and the maximum value. The minimum value may be output, and the parallax control operation may be performed in consideration of the viewing distance of all observers. Further, when a plurality of people observe different windows, if the binocular disparity is controlled by setting an independent viewing distance for each window in response to this, an optimal stereoscopic image can be displayed for each person. .

In the first, second and third embodiments, the appropriate parallax determining section 10 outputs the parallax calculating section 8, the output of the resolution judging section 9, the horizontal length L of the display CRT 1, 2, the visual distance measurement. Although the maximum parallax Dm on the screen is calculated based on the observer's viewing distance ds measured by the unit 16, the entire display CRT screen may not be used depending on the input image signal.
For this reason, the resolution determining unit 9 determines the type of the input image signal (HD
TV, NTSC, EDTV, computer images, etc.) and the size of the display screen. The database is configured so that the magnitude of binocular parallax displayed according to the type of input image signal can be correctly recognized. May be.

In the case of a monitor dedicated to an image signal having a fixed frequency, a resolution determination unit is not necessary, and a fixed value may be given as a product specification. Further, a typical image display size such as 1/2 or 1/3 of the screen size may be given as a fixed value.

Further, in the first, second and third embodiments, the parallax control unit 13 always calculates the calculated parallel movement amount Dc.
May be used, or may be operated only at the start of the operation and when the binocular disparity of the input image has significantly changed.

In the first, second and third embodiments, the button SW is set only when the observer wants to adjust the binocular parallax.
It is also conceivable to issue an adjustment command using a remote control or the like.

In the second embodiment, the final three-dimensional image display is described using a time-division method using a liquid crystal shutter. However, any other method, such as a method without glasses using a lenticular lens or a parallax barrier method, can be used. Such a stereoscopic display method may be used.
