Abstract

We propose a motion adaptive sensor for image enhancement and for a wide dynamic range. The motion adaptive sensor is able to control integration time pixel by pixel. The integration time of each pixel is controlled by saturation and temporal changes caused by detected incident light. By controlling the integration time, we can expect a high temporal resolution in the moving area, a high SNR in the static area, and a wide dynamic range. In this paper, we present a design and an implementation of the proposed sensor based on column parallel architecture. By using this column parallel architecture, integration of processing does not significantly sacrifice fill factor and power dissipation. We have fabricated a prototype using the CMOS 1.0 μm prosess and we show the results of our experiments.
