Method and device for processing video signals for presentation on a display and corresponding computer program product

摘要

An RGB digital video signal destined to be displayed on a display such as a liquid crystal display (LCD) is converted from the RGB color space to the YUV color space. The signal converted into the YUV color space is subjected to at least a processing operation selected among a sub-sampling operation ( 24 ) and a data compression operation ( 26 ). The signal is then stored in a memory and the signal read from said memory ( 12 ) is then subjected to at least a return operation ( 28, 30 ) complementary to the aforesaid processing operation ( 24, 26 ). The signal subjected to the aforesaid return operation is lastly reconverted from the YUV color space to the RGB color space, thus being susceptible to be displayed on the display.
