Abstract
The invention discloses a method for displaying stereo image and a display system applying the method, which is applied to display the stereo image including image data of left eye and image data of right eye. The invention processes the stereo image with time style by using the characteristic of vision persistence of human eyes so that different images can be displayed in the same row in different time on the screen. In this way, vertical resolution of the stereo image can be increased and discontinuity of a picture can be improved.
Description
Technical field
The present invention relates to a kind of 3 D image display method, particularly relate to a kind of being used in the display system (Display system), increase the vertical resolution of stereopsis and improve the method for picture discontinuity.
Background technology
Generally speaking, the 3D stereopsis all is made up of the image data of two groups of different visual angles, and wherein, one group of system is corresponding to the left eye visual angle, and another group then is corresponding to the right eye visual angle.When playing the 3D stereopsis, observer's left eye only can be seen the image data corresponding to the left eye visual angle, and right eye only can be seen the image data corresponding to the right eye visual angle, and by this, the observer promptly can produce stereoscopic vision in brain.
See also Fig. 1, Fig. 1 shows the schematic diagram of the 3D polarization screen 1 of prior art.As shown in Figure 1; for the polarization image that shows that right and left eyes is different; existing 3D polarization screen 1 can be divided into the pixel that screen can show odd-numbered line (Odd line) and even number line (Even line) usually, and wherein odd-numbered line is distributed to left eye, and even number line is distributed to right eye.
See also Fig. 2, Fig. 2 shows the schematic diagram of simple eye image after normal images and the polarization.Because the image way of output of 3D polarization screen 1 is that the right and left eyes data are interlaced, cause the vertical resolution of image only to deposit half of screen.Simultaneously, because the simple eye image of seeing is that inter-bank presents, cause the unfilled corner of image frame or discontinuous easily, and then quality is watched in influence.
Therefore, the purpose of this invention is to provide a kind of 3 D image display method, be used in the display system, increase the vertical resolution of stereopsis and improve the picture discontinuity, and then address the above problem.
Summary of the invention
A purpose of the present invention provides a kind of 3 D image display method, it is the persistence of vision (Persistence of vision) characteristic of utilizing human eye, mode with the time is handled stereopsis, allows the same delegation on the screen demonstrate different images at different time.By this, can increase the vertical resolution of stereopsis and improve the picture discontinuity.
According to a preferred embodiment, 3 D image display method of the present invention is in order to show stereopsis (Stereoscopic image), wherein, stereopsis comprises left-eye images data (Left-eye imagedata) and right-eye image data (Right-eye image data).3 D image display method of the present invention comprises the following step.
At first, receive stereopsis.Then, according to 2N line data in the left-eye images data and the 2N line data in the right-eye image data, produce alternating expression first image frame, and according to 2N-1 line data in the left-eye images data and the 2N-1 line data in the right-eye image data, produce alternating expression second image frame, wherein, N is a natural number.Afterwards, play alternating expression first image frame and alternating expression second image frame in regular turn, or play alternating expression second image frame and alternating expression first image frame in regular turn, to show stereopsis.By this, the same delegation on the screen can demonstrate different images at different time, and then increases the vertical resolution of stereopsis and improve the picture discontinuity.
Can be further understood by the following detailed description and accompanying drawings about the advantages and spirit of the present invention.
