Efficient post-video processing for thin display devices
Jin-Hwan Jeong · IEEE Transactions on Consumer Electronics · 2010
Display devices of portable devices can express very limited colors so that the dithering at the postvideo processing step is inevitable, which degrades greatly the video playback performance. The main cause comes from the huge data size for converting full color YUV to dithered RGB. This paper proposes an efficient post-video processing method that reorders sub-phases of the postvideo processing step so as to lighten the computation and to reduce the data size. This simplifies circuit logic for the post-video processing, so the hardware manufacturing cost can be lower and that consumer devices can drain less battery power for it.
