[Problem] To appropriately assess a rectangular movement area. [Solution] A holding device (604) holds an output movement area from a time (t), and at a time (t + 1), provides said movement area to a specified-area feature detection device (605). At the time (t + 1), the specified-area feature detection device (605) applies to an image from the time (t), and to an image from the time (t + 1), movement coordinates from the time (t) provided by an assessment device (603), computes feature data (d(t)) of the vicinity of the movement coordinates from the time (t); computes feature data (d(t + 1)) of the vicinity of movement coordinates from the time (t + 1); and provides said feature data (d(t), d(t + 1)) to the assessment device (603). From the feature data (d(t + 1)), the assessment device (603) assesses whether a frame exists. |
