Abstract

The invention provides a system and method for modulating the turnover rate of an adaptive frame. A frame processing unit is used for receiving a first frame and a second frame in sequence, wherein the frame processing unit divides the second frame into a plurality of second block frames; a frame change detecting unit is used for detecting the change state between the first and second frames by comparing a first block frame with the corresponding second block frame; a time sequence generator is used for identifying the second block frame of the second frame so as to form the turnover rate of a plurality of frames according to a comparison result of the first block frame with the corresponding second block frame; and the time sequence generator modulates the frame turnover rate of the second frame.

Description

technical field [0001] The present invention relates to a modulation system and its method, in particular to an adaptive picture update rate modulation system and its method. Background technique [0002] With the development of information technology and the rapid development of electronic products, quality is no longer the only choice. Green industry is getting more and more attention, which also means that energy saving and carbon saving are becoming more and more important. On this occasion, the industry has successively proposed ways to reduce power consumption to achieve power saving. For example, most of the power consumption of electronic products (such as notebook computers) is caused by liquid crystal displays (LCDs). The power consumption of a display (LCD) is an urgent problem to be solved at present. [0003] In a known technology, by adjusting the frame rate of the display card of the computer system. The frame refresh rate of the known display card is 60 fra...
