Abstract

We propose a image reconstruction method and a sensor for high-sensitivity imaging using long-term exposed green pixels over several frames. As a result of extending the exposure time of green pixels, motion blur increases. We use motion information detected from highframe-rate red and blue pixels to remove the motion blur. To implement this method, both long- and short-term exposed pixels are arranged in a checkerboard pattern on a single-chip image sensor. Using the proposed method, we improved fourfold the sensitivity of the green pixels without any motion blur.
