INFORMATION PROCESSOR, INSTRUCTION RECOGNITION PROCESSING METHOD AND PROGRAM STORAGE MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide an input interface whose operation is easy and whose operability is excellent for a user. SOLUTION: At the time of recognizing the change of the luminance level of picture data in instruction recognition areas 111-114 in an input picture obtained by image picking up the hand of a user by a CCD camera 8, prescribed scroll operations corresponding to commands preliminarily made correspond to the instruction recognition areas 111-114 are executed so that the scroll operations corresponding to the commands made correspond to the instruction recognition areas 111-114 can be immediately executed only by recognizing the movement of the hand of the user regardless of what kind of movement of the hand of the user in the instruction recognition areas 111-114. Thus, it is possible to provide the input interface whose responsiveness is high without any erroneous recognition.
