    • 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.
    • 视点检测装置包括:视点检测单元,用于检测显示屏上的操作者的视点;校正电路,用于检测和校正操作者的实际视点位置与由视点检测单元检测的视点位置之间的偏差;以及 存储电路,用于存储由校正电路产生并用于校正偏差的校正信息。 该装置具有基于存储在存储电路中的校正信息来校正偏差的模式,以及通过校正电路中的计算来校正偏差的模式,而不使用校正信息。
