Image display method and device

Abstract

Embodiments of the invention disclose an image display method and device. The method comprises the steps of according to display depths of all preset subimages used for synthesizing a target image, a lens intercept T0 and a horizontal distance L between a lens array and a display panel, determining, by terminal equipment, a display area of each subimage corresponding to each display unit on the display panel; according to a pixel mapping relation between each subimage corresponding to each display unit and each display area, acquiring pixel distribution of the display area of each subimage corresponding to each display unit; according to the acquired pixel distribution, acquiring the pixel distribution of each display unit for each subimage; and according to a rule that the pixel distribution of the display unit for the subimage with small display depth covers the pixel distribution of the display unit for the subimage with large display depth, acquiring comprehensive pixel distribution of each display unit, and displaying the target image. Through adoption of the method, the viewing angle is increased while the viewing effect is not affected, so that the user experience is better.

Description

technical field [0001] Embodiments of the present invention relate to the field of terminal applications, and in particular to an image display method and device. Background technique [0002] With the development of science and technology, the three-dimensional display technology of images on terminal devices is also becoming more and more advanced. Three-dimensional display can provide users with a rich visual experience, and the three-dimensional effect makes users feel as if they are on the scene of the display scene. Therefore, in recent years, the implementation methods of three-dimensional display technology have emerged in an endless stream. [0003] Among them, integrated imaging technology is a very effective three-dimensional display method. Such as figure 1 As shown, it is a schematic diagram of the integrated imaging display principle. The display panel and the lens array are arranged in parallel, and the distance between the two is g, and the lens intercept i...

Problems solved by technology

like figure 1 As shown, it is a schematic diagram of the integrated imaging display principle. The display panel and the lens array are arranged in parallel, and the distance between the two is g, and the lens intercept is p. According to the principle of light propagation, it can be known that the viewing angle of the user in the figure is fixed 2θ, that is, the user can see the normal object point Q within the 2θ viewing angle, but in this way, if the user is outside the viewing area, he can also see a repeated object point Q′, so the user’s viewing angle is limited and the experience is not good. good

from figure 1 It can be seen that 2θ=2arctan(P / 2g), increasing P can increase the viewing angle, but increasing P will also reduce the display resolution, which also affects the viewing experience of users
