Abstract
A frame brightness detecting unitdetects a frame brightness value of each of a plurality of image frames. A flicker spectrum detecting unitdetects, from the frame brightness values of 512 frames, spectrum values at frequencies, such as 100 Hz, 200 Hz, and 300 Hz. A brightness estimating unitestimates a brightens value of a light source from the spectrum values. An encoding unituses a reciprocal of the estimated brightens value to determine a reference frame. The encoding unitalso uses the reciprocal in an evaluation function for motion vector estimation. The image frame is encoded using the motion vector.
