Abstract

The invention provides an image frame coding method and an image frame coding device, and relates to the technical field of image processing, being capable of solving the problems that in an image frame coding process, the coding efficiency is low and the coding time is relatively long. The specific technical scheme of the method comprises the steps of acquiring a target image frame which comprises at least one macro block; when an infection parameter of the target macro block is more than or equal to a preset threshold, using the target macro block as the macro block to be coded to be added into a code caching queue; when the macro block to be coded in front of the target macro block is moved out of the code caching queue, using the target processing unit to code the target macro block; and generating a coded target image frame after all macro blocks of the target image frame are coded. The method and the device provided by the invention are used for coding the image frame.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular to an image frame encoding method and device. Background technique [0002] In the process of image transmission, the image frame needs to be encoded first, and then transmitted. After the image frame is received, the image frame needs to be decoded and then displayed. In the process of image encoding, an image frame is divided into at least one macroblock, and when encoding a macroblock, adjacent encoded macroblocks are referred to. In related technologies, an image frame is divided into multiple units, each unit contains several macroblocks, each unit is independent of each other, and encoded at the same time, because there is no correlation between each unit, resulting in an increase in the code stream, and the encoding The fast unit has to wait for the coding of the slow unit to complete before proceeding to the next step, which increases the processing ti...
