Abstract

The invention provides an image encoding method, an image decoding method, an electronic device and a readable storage medium, and relates to the technical field of image processing. The image encoding method comprises the following steps: respectively acquiring a first width and a first height of an input image; according to the first width and the first height, obtaining a second width and a second height, and the second width and the second height being both even numbers; applying for a first memory for the input image according to the second width and the second height; and storing the input image in the first memory to obtain image information in a YUV format. In this way, system crash caused by different sizes of input images is avoided, and it can be guaranteed that system performance is not affected.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image encoding and decoding method, electronic equipment and a readable storage medium. Background technique [0002] YUV (also known as YCrCb) is a color coding method adopted by the European television system (belonging to the TV broadcasting system (Phase Alteration Line, PAL), is the PAL and SECAM system (SECAM), which means "in order to transmit color and storage ") The color space used by the analog color TV system. Y stands for brightness, uv stands for color difference, u and v are the two components that make up the color. YUV_NV21 is one of the YUV formats, often used in embedded devices such as ANDROID .YUV_NV21 belongs to 4:2:0 sampling, and every four Ys share a set of VU components, which takes up less storage space than JPG, YUV444, YUV422, etc. figure 1 It is a memory diagram of YUV_NV21, which is divided into Y plane and VU plane. In VU plane, VU is ...
