    • An element determining unit detects an element that should be excluded from an object of comparison, of an image. Using the image with the detected element removed, comparing process is performed. Specifically, a feature value calculating unit calculates, in correspondence to each of a plurality of partial images in the image, a feature value in accordance with a pattern of the corresponding portion. The element determining unit detects an area represented by a combination of partial images having a prescribed calculated feature value, as the element to be excluded from the object of comparison. Based on the ratio of the detected elements as non-eligible for comparison to the image as a whole and on the result of comparison, activation of an application is permitted/inhibited.
