Problems solved by technology

Based on the above principles, display devices such as televisions and monitors only need to present the left-eye picture and right-eye picture of the same object to people's left and right eyes respectively, so that people can have a three-dimensional perception of the picture they see; in order to achieve For this purpose, people have developed many 3D display technologies, such as shutter 3D, glasses-free 3D, polarized 3D, etc., but these technologies will more or less have crosstalk when presenting 3D images to human eyes, that is, People's left eye receives part of the right-eye picture, and the right eye also receives part of the left-eye picture, so that the picture people see will produce a double image, which will lead to a decrease in the comfort of the viewer
[0004] At present, some technologies are used to reduce the influence of crosstalk. For example, for shutter 3D, the main way to reduce crosstalk is to use a 240Hz LCD screen. The 240Hz LCD screen inserts a black field between the left and right eye images to achieve the purpose of reducing crosstalk. This method is effective, but the panel cost is higher

Abstract

The invention is suitable for the field of digital image processing, and provides a method for eliminating left and right eye image ghosting, a ghosting eliminator and a 3D (three dimensional) player. The method comprises the following steps of: carrying out template matching operation to a left eye image and a right eye image to obtain a deviation value between the left eye image and the right eye image at each coordinate; and according to the deviation value, simultaneously carrying out offset operation to the left eye image and the right eye image. In the embodiment of the invention, the left eye image and the right eye image are subjected to the template matching operation to obtain the deviation value between the left eye image and the right eye image at each coordinate; the left eye image and the right eye image are simultaneously subjected to the offset operation according to the deviation value; the purpose that the ghosting caused by interference in 3D display is relieved is achieved by reducing the parallax between the left eye image and the right eye image; and the third dimension of a 3D-displayed picture is kept, while the ghosting phenomenon caused by interference is relieved, and the discomfort of watchers is reduced.

Description

technical field [0001] The invention belongs to the field of digital image processing, and in particular relates to a method for eliminating ghost images of left and right eyes, a ghost eliminater and a 3D player. Background technique [0002] 3D display technology is one of the hot fields of research and application at present. With the popularization of 3D display technology, movie theaters are no longer the only choice for people to experience the impact of stereo vision; Come watch 3D movies, play 3D games, and enjoy the unique experience brought by stereoscopic images. [0003] The reason why we can experience stereoscopic vision is that the two eyes of human beings have a certain space distance (about 6-7cm), so the scene seen by the left eye will be slightly different from the scene seen by the right eye. This difference is parallax. The human brain can interpret the parallax in the scene of the left and right eyes and judge the distance of objects in the scene accor...
