Abstract

The invention provides a method for removing integral imaging three-dimensional displaying crosstalk images. The method respectively searches corresponding three-dimensional information and crosstalk information on a three-dimensional visual area and a crosstalk area, replaces the crosstalk information with blank information in each image element, and acquires crosstalk-free micro-image arrays. During integral imaging three-dimensional display, viewers can still view integral three-dimensional images in an original three-dimensional visual area, yet view blank images in the crosstalk area where crosstalk images are originally viewed, and occurrence of the crosstalk images is avoided.

Description

technical field [0001] The invention relates to integrated imaging three-dimensional (3D) display technology, in particular to a method for eliminating crosstalk images in integrated imaging 3D display. Background technique [0002] Integrated imaging is a true 3D display technology. Taking the vertical direction as an example, as attached figure 1 Shown is a schematic diagram of distribution of stereoscopic viewing areas and crosstalk areas of a conventional integrated imaging 3D display device. When the light emitted by the pixel on the image element is seen by the viewer through its corresponding lens element, the viewer's position is the main viewing area; the light emitted by the pixel on the image element is seen by the adjacent lens element When , the position of the viewer is the first-order viewing area; when the light emitted by the pixel on the image element is seen through the second adjacent lens element, the position of the viewer is the second-order viewing ...
