WT8892数据手册Weltrend中文资料规格书

描述 Description

The WT8892 is a highly-integrated video processor SoC dedicated for ADAS applications. The chip includes CVBS input from 4 channel video decoders, 4 individual contrast/brightness adjustment function, input image position adjustment function to correct the camera assembling error, video image processing, fisheye correction, perspective adjustment, combine front/rear/left/right four images to top view with adjustable image size and boundary fusion processing, output video contrast/brightness/sharpness adjustment, OSD, video encoder, output interface with one analog NTSC/PAL CVBS or digital CCIR 656/601 output, serial flash memory for OSD, external 256Mb DDR for video buffer, and SPI/I2C interfaces. Most AVM chips are DSP-based solution, but this chip is hardwired ASIC which provides cost-effective solution with low-power consumption compared to its counterparts in the market.
