The apparatus comprising: a mechanism for moving an object; an information acquisition unit acquiring a driving amount information of the mechanism; a sensor for capturing a surface of the object; a processing section for processing a first image data and a second image data acquired by the sensor at different timings; and a control unit for controlling the mechanism, wherein: the processing section performs processings of: (a) cutting out an image pattern of a part of the first image data; (b) limiting a search range in the second image data within which a similar region similar to the image pattern is searched; (c) searching the similar region within the limited search range in the second image data; and (d) obtaining the moving information of the object based on a positional relation between the image pattern in the first image data and the similar region in the second image data. |
