AMT630M

AMT630M

1. General Description

AMT630M is a SoC chip that can change frame of input digital image signal and then output the display. It supports the following input format: ITU656、ITU601、 BT1120 and parallel input RGB888. Users can select video input sources with a variety of flexible options. AMT630M has high-powered digital processing built-in modules of 2D noise reduction, sharpness, transient response enhancement of luminance / chrominance, gamma correction, image dithering and so on. Images can get better noise suppression, higher degree of resolution and better image quality after the chip processing. AMT630M supports normal font OSD and true-color AOSD to meet different needs. Video layer and OSD layer can be blended before or after image processing in AMT630M. It supports the output of mirror image, rotated image and FRC(frame rate conversion). AMT630M is implemented with high-performance arbitrarily scaled engine with stepless zooming. AMT630M supports to display video on the screen of parallel RGB, serial RGB, CPU, single-channel/two-channel LVDS, MIPI and so on.
