摘要
An accurate motion vector is locally estimated in a moving image, and motion compensation is performed on the image in the immediately preceding frame based on the motion vector obtained. Next, a low pass filter is applied between the current frame and the immediately preceding frame that has been motion compensated. By controlling the filter coefficient in pixel units when the filter is applied, blurring of a moving image is suppressed to a minimum while noise is largely reduced.
