Abstract
A huge computational complexity of motion vector (MV) estimation is the main contributor to the large power moving picture encoders. For high definition image, it is difficult to implement a onechip MV estimator. This paper proposes a CMOS image sensor with high-speed interpolated image sensing and an iterative block matching methods to estimate MV using the interpolated pictures. The proposed method reduces the computational complexity greatly. In order to improve the image quality of the high-speed interpolated pictures, this paper also proposes a new technique for interpolated image sensing, so called a bidirectional multiple charge transfer. Analysis results of the proposed sensor are also shown.
