An image motion detecting circuit and an image motion detecting method of the present invention can accurately detect motion of such an image sequence that different still pictures are connected with each other. Inter-frame difference absolute values of an inputted image signal during a predetermined frame period are held by plural registers 105. Then, the maximum value is extracted from the inter-frame difference absolute values which are held by the plural registers 105, and the extracted maximum value is subtracted from the sum of the inter-frame difference absolute values during the predetermined frame period, thereby detecting the motion of the whole image sequence. |
