Abstract: There is disclosed an optically transparent pressure sensitive adhesive sheet for heat transfer image pattern formation comprising an optically transparent film which has a first side constituting a heat transfer image pattern-receiving side and a second side opposite to the first side, an antistatic release sheet provided on the second side of the optically transparent film, via a pressure sensitive adhesive layer. Also disclosed is a first embodiment of an optically transparent decorative pressure sensitive adhesive sheet comprising the optically transparent pressure sensitive adhesive sheet and an image pattern formed by heat transfer method on the first side of the optically transparent film.

Abstract: In order to detect a motion vector representing a movement of an objective area in a first image of a plurality of successive images, first, a plurality of comparison areas are determined in a second image before or after the first image. Subsequently, a difference total sum between the objective area and each of the comparison areas is obtained with respect to the plurality of comparison areas, thereby obtaining a distribution of the difference total sums. The resultant distribution of the difference total sums is approximately expressed in the form of a predetermined polynomial. By using this polynomial, the position is obtained where the difference total sums become minimum. By treating the resultant position of the area as the position before or after the movement of the objective area, the motion vector representing the movement of the objective area is detected.
