Abstract

The present invention discloses one kind of color space transformation method for compressing 16-bit color image. On the basis of traditional image or video compression technology, such as JPEG sequence, MPEG sequence and H.26X sequence, one conversion from 24-bit RGB format to 16-bit RGB format is increased to the encoding end, and the color space transformation method is used to eliminate the redundant information in the input end and simplify the operation steps in the decoding end, so as to reduce the decoding complexity and raise the video compression quality.

Description

technical field

[0001] The invention relates to the field of multimedia technologies related to portable mobile devices, in particular to a color space conversion method for compressing 16-bit color images. Background technique

[0002] With the popularization of portable mobile devices, such as personal digital assistants (PDAs), mobile phones, etc., a large number of multimedia applications based on portable mobile devices have emerged. Portable mobile devices have problems such as weak computing power, short battery life, and 16-bit color LCD panels; and in multimedia, the computational complexity of video decoding is relatively high, so traditional video encoding methods for portable mobile devices cannot meet the requirements. Users' requirements for multimedia, especially video technology-related applications. According to the inherent characteristics of portable devices, the transformation of general video codec technology can improve the processing speed of video de...
