Abstract
A frame rate is determined in accordance with the smoothness in movement of a video. An amount of change detection section extracts an amount of change based on a plurality of frame pictures included in an input video signal input as a moving picture signal from the outside and outputs an amount of change to an evaluation value calculation section. The evaluation value calculation section computes an amount of change in time between each of the frame pictures based on the amount of change and the time interval between frame pictures based on frame rate information and evaluates an evaluation value for evaluating the smoothness in movement of an input video based on the amount of change in time. The evaluation value is output to the outside as a factor for determining a frame rate.
