Stereoscopic image display method

The present invention relates to a method of image display, and more particularly to a method of stereoscopic image display.

Three-dimension (3D) display technology is the trend of digital display today. Whether in entertainment, medical research or other fields, users are increasingly immersed in the experience of immersion. In terms of entertainment, while the user watches a 3D movie or plays a stereo game, the stereoscopic display technology can display the visual effect that the object in the picture is emitted toward the viewer and flies out of the screen, and often brings the user experience. The feeling of its environment, so stereoscopic display technology has brought new trends and development goals for movies and games.

Stereoscopic display technology uses the brain to fuse different images seen by the left and right eyes to create a stereoscopic image. Wherein, the spatial multiplexing method is to simultaneously project images to the left eye and the right eye in the same display panel, that is, half of the pixels of the display panel are used to display the image corresponding to the left eye, and the other half of the display panel is used to display the corresponding The image of the right eye, so the resolution of the stereo image will be half of the 2D image (ie, the planar image). Further, the stereoscopic image is formed by the plane image corresponding to the left eye and the plane image corresponding to the right eye, but only half of the pixels in the display panel are used to display the plane image corresponding to the left eye, and the plane image corresponding to the left eye is The undisplayed portion is usually discarded. Similarly, the undisplayed portion of the flat image corresponding to the right eye is discarded. According to the above, the conventional spatial multiplexed stereoscopic display technology may cause part of the left eye image and part of the right eye image to be undisplayed. Therefore, in the stereoscopic image, there may be a situation in which the left and right eyes are asymmetrical, thereby causing stereoscopic The obstacles and discomfort of the image in viewing.

The present invention provides a stereoscopic image display method, which can enable the stereoscopic image displayed by the spatial multiplexed stereoscopic display technology to include complete information of the left eye image and the right eye image, thereby eliminating the display space multiplexed stereoscopic display technology. Discomfort caused by stereoscopic images.

The present invention provides a method for displaying a stereoscopic image, the method comprising the steps of: receiving an original first eye image and an original second eye image; and respectively, the plurality of first display data in the original first eye image and the original first eye image respectively The second display data is proportionally averaged to generate a plurality of first eye image display materials, wherein the first display data respectively correspond to the plurality of first pixels of the display panel; and the plurality of third display data of the original second eye image respectively A plurality of second eye image display materials are generated after the ratio is averaged with the plurality of fourth display materials in the original second eye image, wherein the fourth display data respectively correspond to the plurality of second pixels of the display panel, and the second pixels are respectively Different from the first pixels; writing the first eye image display materials to the first pixels to display the first eye images; writing the second eye image display materials to the second pixels to display the second eye image.

Based on the above, the present invention generates the first eye image display data by proportionally averaging the first display data in the original first eye image and the second display data in the original first eye image. And, the third display data in the original second eye image is proportionally averaged with the fourth display data in the original second eye image to generate the second eye image display data. Thereby, the stereoscopic display image displayed by the same display panel can include complete information of the left eye image and the right eye image to eliminate the discomfort caused by viewing the stereo image.
