Abstract

Embodiments of the invention provide an image hardware coding processing method and device. The method comprises the steps of acquiring image data; at least according to part of configuration information, performing data processing on the image data on a framework layer of an operating system, wherein the configuration information comprises at least one of a size conversion instruction, a format conversion instruction and an algorithm processing instruction; and sending the image data subjected to the data processing and a hardware coding instruction to hardware for carrying out coding. According to the image hardware coding processing method provided by the embodiment of the invention, the framework layer can be used for processing operation of at least one of size conversion, format conversion and algorithm processing, and the image data with various sizes and formats can be provided and is converted to be in a data form which can be processed by the hardware in the framework layer,for hardware coding, so that repeated data interaction between an application and bottom hardware in the prior art is avoided, the coding efficiency is improved, and the processing flexibility is alsoimproved.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to an image hardware encoding processing method and device. Background technique [0002] Coding for images is the act of encoding and compressing images using image compression standards. Take JPEG image as an example. JPEG is an international image compression standard. The JPEG image compression algorithm can provide good compression performance while having relatively good reconstruction quality, and is widely used in image and video processing fields. [0003] Image encoding and compression can be implemented by software encoding or hardware encoding. Hardware encoding generally uses a dedicated chip, which has better performance and power consumption than software encoding, especially the speed advantage of hardware encoding, which is the main reason for choosing hardware encoding for large-size images. [0004] In an electronic device, there are a bottom h...
