PROBLEM TO BE SOLVED: To solve such a problem that it is hard to catch a moving object moving in a wide area with the sufficient resolution and it is hard to discriminate the degree of the action of the moving body. SOLUTION: A parameter input unit 2 inputs the control parameter for changing the range of a specified area and a concentration value in an image at a predetermined rate, and a diffusion computing unit 3 separates the moving image of the moving object into an object image and the background image, and assigns a predetermined concentration value to picture elements of an area in which the object image exists at a predetermined time, and changes the range of the described area and the concentration value with the lapse of time on the basis of the control parameter. An action recognizing unit 4 extracts the feature quantity from the distribution of the concentration value in a described area, and recognizes the action of the object on the basis of the collation of the feature quantity with a specified value.
