Video signal processor ics enhance picture quality for small lcd panels

The devices target applications such as vehicle reversing cameras, in-vehicle navigation systems and various consumer video monitoring security systems where small lcd screens are utilised. The LC749000PT for automotive applications and the LC749000AT for consumer products, support important end application energy savings and utilise advanced signal technology to improve the picture quality of digitally compressed images. They are capable of supporting installations with screen resolutions up to wide video graphics array and integrate an a/d converter which receives direct analogue picture signal inputs from a camera. The built- n picture decoding circuit is able to decode analogue picture signals in both NTSC and PAL formats. The size of the decoded picture signal is then adjusted according to the resolution of the connected lcd panel by a scaler to enhance the picture quality. The 24bit RGB output or 18bit rgb output with dithering function is then transferred to the application lcd panel by a built in programmable timing controller.
