Abstract
A plurality of motion detecting units of which at least a template block size, i.e., the number of estimation pixels, or a search area size is different among the motion detecting units are used adaptively according to the characteristic of, or the prediction coding type of, a target picture. This enables efficient motion vector detection to be accomplished without increasing the amount of hardware or power consumption.
