Outline of Final Research Achievements

Recent CMOS image sensors have several image acquisition modes such as (1) high-resolution and normal-frame-rate and (2) low-resolution and high-frame-rate. Assuming these two types of video, that is high-resolution video and high-frame-rate video, can be obtained simultaneously, a motion-compensated frame interpolation method to generate high-resolution and high-frame-rate video from these videos is proposed. By using the proposed approach, efficient video acquisition can be archived. Considering adaptive processing based on motions in video sequences, a image shrinking based high-speed moving region extraction method is also proposed.
