ABSTRACT:
A disclosed device detects an observer's visual axis bi-directionally, comprising a light receiver for receiving light from the observer's eyeball via multiple photoelectric transfer element arrays, a first storage means for storing positions of photoelectric transfer elements outputting signals representing Purkinje images; a second storage for referencing the photoelectric transfer signals originating from multiple photoelectric transfer elements arranged in the horizontal and vertical directions of the light receiver, and storing the positions of photoelectric transfer elements that indicate characteristic points representing the pupil of an eyeball, and a detector for detecting a view point using the positional information stored in the first and second storages.
