Video Enhancement Sensor Using Motion Adaptive Storage Time

We propose a video enhancement sensor for smoothing random noise and getting wide dynamic range. The sensor has computational elements based on a column-parallel architecture. It detects motion and saturation of the stored charge on photo diode independently pixel by pixel. By operation at high frame rate, 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 wide dynamic range. In this paper, we discuss the principle, circuit design and layout of motion adaptive sensor.
