Algorithm and architecture design of adaptive brightness correction for video application

According to the overviews and analysis of adaptive brightness correction, we provide an available solution for the interference of environment light in digital cameras, but current methods are still not suitable for VLSI design. In this paper, we propose an efficient method, called local bi-histogram equalization (LBHE), to remedy the local visibility and control the degree of enhancement. We utilize the hybrid architecture to implement adaptive scheme with MPEG system. The hybrid architecture design actively reduces the implementation area and successfully applies our LBHE in MPEG processing. Through the comparison content, we can find that our design can exactly satisfy the chip specification of real-time processing. Hence, our chip implementation is efficient in achieving motion and brightness estimation in the MPEG architecture. Then this design can cause that our chip become compatible to current video application.
