ABSTRACT:
A viewpoint detection apparatus includes a viewpoint detection unit for detecting the viewpoint of an operator on a display screen, a correction circuit for detecting and correcting any deviation between the actual viewpoint position of the operator and the viewpoint position detected by the viewpoint detection unit, and a storage circuit for storing correction information which is generated by the correction circuit and used for correcting the deviation. The apparatus has a mode of correcting the deviation based on the correction information stored in the storage circuit, and a mode of correcting the deviation by a calculation in the correction circuit without using the correction information.
