Abstract
A data processing apparatus has a compressor and an output interface. The compressor receives an input display data, and generates an output display data according to the input display data. The output interface packs the output display data into an output bitstream, and outputs the output bitstream via a display interface. The compressor adaptively adjusts a compression algorithm applied to the input display data according to visibility of compression artifacts. By way of example, the display interface may be a display serial interface (DSI) standardized by a Mobile Industry Processor Interface (MIPI) or an embedded display port (eDP) standardized by a Video Electronics Standards Association (VESA).
