The issue designs a high-definition digital processing platform, present algorithms of image sensor decoding and image enhancement pre-processing and its implementation. Firstly, the framework of the high-definition digital processing platform is introduced. Then the image sensor decode algorithm is given in detail. Finally the paper introduces the framework of the pre-processing algorithm. The major function block of the pre-processing algorithm is discussed in detail, including image filtering, image sharpening, gamma correction, white balance. Experiment results prove that the proposed method improves the image quality captured by CMOS sensor effectively.
