PROBLEM TO BE SOLVED: To more accurately detect components including even an angular component. SOLUTION: A filter generation processing means 1A sets an area for each component constituting a reference filter used for image processing. When a filter which will be a standard is rotated to an angle with a component which will be the center of the filter which will be the standard at the center, computes how will the area of each component constituting the filter after rotation be divided and included in the area set for each component constituting a new filter, for each component constituting the filter after the rotation by a ratio of the area, divides the numerical value of each component on the basis of the ratio, and adds a value which corresponds to the area and is obtained by the division, for each area of each component constituting the new filter to obtain the value of each component constituting the new filter.
