Abstract
According to one embodiment, a movement detection apparatus includes an arithmetic module, an edge-storing filter, a determination module, and a control module. The arithmetic module calculates a difference signal between an input image signal and an image signal of the previous frame. The filter performs smoothing processing for a signal falling within a level range provided as threshold value, among difference signals calculated by the arithmetic module. The determination module determines levels of a movement component and a noise component of the signal output from the filter. The control module controls a level range supplied as threshold value to the filter in accordance with an amplitude level of the noise component overlying the input image signal.
