Abstract
A close-up shot detection device includes motion detection element that calculates the amount of motion between at least two frames or fields constituting a video image every predetermined unit which is composed of one pixel or a plurality of adjacent pixels constituting the frame or field; binarization element that binarizes the calculated amount of motion; large-area specifying element that specifies, as a large area, a connected area in which the number of units is equal to or larger than a predetermined threshold, among connected areas which are obtained by connecting a predetermined number of units having the same binarized amount of motion; and close-up shot specifying element that, when at least one of preset criteria for the specified large area satisfies a predetermined condition, specifies a frame or field having the specified large area as a close-up shot. Consequently, a close-up shot can be easily and rapidly detected.
