Abstract
A motion detection device () receives a signal indicative of a moving image and detects motion between frames with respect to each block region consisting of one or a plurality of adjacent pixels constituting each frame constituting the moving image, and includes: a difference calculation section () for obtaining a difference signal (S) indicative of a difference between adjacent two frames; a first edge detection section () for obtaining, with respect to each block region, a first edge signal (S) included in one of the two frames; a second edge detection section () for obtaining, with respect to each block region, a second edge signal (S) included in the other of the two frames; an edge calculation section () for obtaining, with respect to each block region, an edge signal (S) by adding a product of the first edge signal (S) and a first coefficient to a product of the second edge signal (S) and a second coefficient; and a division section () for obtaining, with respect to each block region, a motion signal (S) by dividing the difference signal (S) by the edge signal (S).
