Abstract
A data processing apparatus has a compressor and an output interface. The compressor receives an input multimedia data, and generates an output multimedia data according to the input multimedia data. The output interface packs the output multimedia data into an output bitstream, and outputs the output bitstream via a camera interface. The compressor adaptively adjusts a compression algorithm applied to the input multimedia data according to visibility of compression artifacts. By way of example, the camera interface may be a camera serial interface (CSI) standardized by a Mobile Industry Processor Interface (MIPI).
