METIS
8~13M pixel sensor support High Quality Image Signal Processing (ISP) IP

Chips&Media’s Camera ISP IP – METIS (hereafter will be referred as METIS ISP) is Image Signal Processing (ISP) IP developed to be used automotive and surveillance such as Around View Monitor / Surround View Monitor, Dash Cam, Autonomous Driving assistant and IP Camera with maximum processing resolution of 13 Mega Pixels (MP) at 60 frames per second (FPS). The ISP offers complete and configurable ISP pipeline with multi-instances to process up to 4 inputs from CMOS sensors simultaneously, where is required by applications such as AVM/SVM and multi-camera surveillance system. Moreover, the METIS ISP IP includes features including 18x18 2D Color-Shading Correction, 19-Point Bayer Gamma Correction, 6-Region Color Saturation, Hue, and Delta-L Control functions, and generates best possible picture quality by implementing optimum low light Noise/Sharp filter on the input image after analyzing each scene. METIS ISP is ARM® AMBA AXI protocol compliant that the host can control METIS via AMBA APB bus interface, and data are exchanged using AMBA AXI interfaces.
