Because smaller pixels result in reduced sensitivity, the exposure time must be increased. However, when capturing fast-moving objects with longer exposure times, blurry images are unavoidable. To solve this problem, bracketing and burst imaging have recently been reported [1]. These techniques combine multiple RGB frames into a single frame. To capture high-speed objects with the same exposure time, the number of frames and output frame rate are increased. As a result, the power
