Overview:
The Camera ISP IP is an Image Signal Processing (ISP) IP developed for low-light environments in surveillance and automotive applications, supporting a maximum processing resolution of 13 Mega or 8Mega Pixels (MP) at 60 frames per second (FPS). It offers a configurable ISP pipeline with features such as 18x18 2D/8x6 2D Color Shading Correction, 19-Point Bayer Gamma Correction, Region Color Saturation, Hue, and Delta L Control functions. The ISP IP enhances image quality with optimal low-light Noise/Sharp filters and offers benefits such as low gate size and memory usage through algorithm optimization. The IP is also ARM® AMBA 3 AXI protocol compliant for easy control via an AMBA 3 APB bus interface.
