• Very small area require.

 

Each module of the image Signal Processing Pipeline, proposed by DPControl, has been implemented respecting the compatibility with the AMBA AXI4 standards, making the entire architecture completely configurable and versatile. The ISP accepts in input a video stream with 8 or 10 or 12 bits depth. The Defective Correction module takes care of eliminating the Salt-Pepper error. The Color Filter Array is an implementation of the Malvar-Cutler algorithm, widely appreciated in literature and increasingly requested in the vision world. Statistics on the video stream are captured for possible adaptive control algorithms and applied color and gamma corrections. Color conversion in YUV space with color sub-sampling 4:2:2 or 4:2:0 is supported.
