Image display method and device

Abstract

The present invention discloses a picture display method and device and belongs to the display technical field. The method includes the following steps that: when a picture rotation instruction is detected, the picture is compressed along a compression direction according to a rotation direction and a rotation angle which are carried by the picture rotation instruction, wherein the compression direction is perpendicular to the rotation direction; the picture which has been compressed along the compression direction is divided into a plurality of picture areas; the plurality of picture areas are compressed along the rotation direction according to the rotation direction and the rotation angle; and the plurality of picture areas which have been compressed along the rotation direction are displayed. According to the picture display method and device provided by the embodiments of the invention, the picture is compressed along the compression direction, and the plurality of picture areas are compressed separately along the rotation direction, and therefore, the entire picture has a perspective three-dimensional effect; and a 3D engine is not required to be loaded, so that the hardware operating costs of a terminal are decreased.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method and device for displaying pictures. Background technique [0002] With the rapid development of display technologies, terminals have more and more display functions. For example, when a terminal displays pictures, it can not only display pictures with two-dimensional effects, but also display pictures with three-dimensional effects. [0003] In order to display pictures with three-dimensional effects, 3D engines such as OpenGL and DirectX can usually be installed on the terminal. The realization process for the terminal to display pictures with three-dimensional effects based on the 3D engine can be as follows: when the terminal detects a picture rotation operation, it calls the 3D engine included in the A graphics processing algorithm is used to process the picture with two-dimensional effect to obtain a picture with three-dimensional effect, and then the terminal disp...

Problems solved by technology

[0005] In the 3D engine, for the graphics with complex structure and shape in the picture, the corresponding graphics processing algorithm will be more complicated, and the time to execute the graphics processing algorithm will be longer, which not only reduces the display efficiency of the picture with 3D effect, but also The hardware operating cost for the terminal to execute the graphics processing algorithm will also increase accordingly
