Title:
PICTURE PROCESSING METHOD AND RELATED DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/231710
Kind Code:
A1
Abstract:
Embodiments of the present application disclose a picture processing method and a computer device, which can be used in the field of computer file management, and specifically in a decoding scenario and an encoding scenario of picture files. The method comprises: obtaining a first picture file; performing arithmetic decoding or asymmetric digital system decoding on the first picture file to obtain a first direct current coefficient and a first alternating current coefficient; performing inverse quantization and inverse discrete cosine transform on the first direct current coefficient and the first alternating current coefficient to obtain a picture file in a YUV format; and converting the picture file in the YUV format into a picture file in an RGB format. According to the method, the decoding process of the picture file is simplified, so that the processing procedure of the picture file is more flexible, and the system complexity and resource overhead are reduced.
