Abstract :
This paper proposes a system of video display and capture. The advantage of this platform is miniaturization, and the size is just as big as a 2.8 inch LCD screen. The hardware platform mainly consists of a DSP and other ICs such as video AD, video DA and LCD control chips. We get video data from a camera and show it on a video display and a LCD screen. The same time system implements digital zoom and LCD screen touch controlling and modulating video contrast and brightness.
