PROBLEM TO BE SOLVED: To appropriately determine a rectangular movement area.SOLUTION: A holder 604 holds an output movement area at a time t, and gives it to a specified area feature detector 605 at a time t+1. The specified area feature detector 605, at the time t+1, applies a movement coordinate at the time t given from a determiner 603 to an image at the time t and an image at the time t+1, calculates feature data d(t) around the movement coordinate at the time t and feature data d(t+1) around a movement coordinate at the time t+1, and gives them to the determiner 603. The determiner 603 determines whether a frame exists on the basis of the feature data d(t+1). |
