Abstract: A pointing device includes a sensor obtaining image information, and an image producing unit producing a comparison image at predetermined time intervals by lowering a spatial resolution of an image based on the image information obtained by the sensor and increasing a density resolution of the image based on the image information. The device arithmetically obtains a correlation value indicating a correlation between a predetermined region in a first comparison image among the plurality of comparison images produced by the image producing unit and a predetermined region in a second comparison image produced after the first comparison image.

Abstract: A pointing device that does not limit an operator by personal physical characteristics is structured as follows. An apparatus incorporating a pointing device includes a fingerprint sensor obtaining image information, a cover protecting a sensor surface, and a sensor presser arranged at a face of the cover on the sensor side so as to be in contact with the sensor surface. The shape of sensor presser obtained with sensor changes by the position on cover being pressed by a finger, and an input is performed based thereon.
