Abstract
Frequency analysis is performed on an image signal on a pixel by pixel basis or on a block by block basis, each block including a plurality of pixels, for each frame of the image signal. Then, a motion level or blur level is calculated on a pixel by pixel basis or on a block by block basis in accordance with a result of the frequency analysis. After the calculated motion level or blur level is converted into a binary value, 2-dimensional continuous regions are detected and a large region is extracted from the detected regions. It is then determined whether the large region is a blocker part based on at least one of an area ratio, a shape, and a position of the large region.
