Motion-adaptive image sensor for enhancement and wide dynamic range

Abstract

We propose a motion adaptive sensor for image enhancement and wide dynamic range, which has computational elements based on a column-parallel architecture. The proposed sensor not only operates at high frequency but also detects motion and saturation of the stored charge on photo diode independently pixel by pixel. The motion adaptive sensor is able to control the suitable storage time in each pixel which results in no motion-blur and no saturation so that it is expected to have high temporal resolution in the moving area, high SNR in the static area and also an effect resulting in wide dynamic range. In this paper, we discuss the principle, design of motion adaptive sensor and some results of simulations.
