Step 101: the BMP view data that image frame generation module (10) transmits according to high-level interface module (23) or logic picture data generate corresponding image frame, and the view data of described image frame and picture synchronization signal are divided into corresponding multilink viewdata signal and multilink picture synchronization signal according to the requirement of required transfer rate by image frame generation module (10);
Step 102: above-mentioned multilink viewdata signal and multilink picture synchronization signal are carried out buffer memory by image buffer storage module (11);
Step 103: the multilink viewdata signal after buffer memory is sent to rgb image data generation module (13) and is reduced into corresponding rgb image data by image buffer storage module (11); Multilink picture synchronization signal after buffer memory is sent to RGB picture synchronization signal generation module (12) and is reduced into corresponding RGB picture synchronization signal by image buffer storage module (11);
The RGB picture synchronization signal of reduction is transferred to RGB image synchronization module (14) by step 104:RGB synchronizing signal generation module (12); the rgb image data of reduction is transferred to RGB image synchronization module (14) by rgb image data generation module (13); the RGB picture synchronization signal of above-mentioned reduction and the rgb image data of reduction synchronously process by RGB image synchronization module (14), guarantee that the rgb image data of RGB picture synchronization signal and the reduction of reducing can keep exporting simultaneously.
