Sight line detector
专利汇可以提供Sight line detector专利检索，专利查询，专利分析的服务。并且PURPOSE: To easily detect the sight line of a patient without permitting the patient to visually recognize the light source of an illuminating means by illuminating the eye ball of the patient with plural illuminating means.
CONSTITUTION: An eye ball 101 of the patient is illuminated by plural illuminating means 4a, 4b 6a and 6b, and image-forming positions on the prescribed surfaces of plural images are detected by detecting means 7 and 9 as the whole of plural cornea reflected images (e) and (f) and iris images (a) and (b) of the eye ball 101 based on a reflected light from a cornea 1 of the eye ball 101 of the plural illuminating means. The sight line of the patient is obtained by utilizing an output signal from the detecting means. As a result, without increasing the optical output of the light source too much and without permitting the patient to visually recognize the light source to be one part of the illuminating means, the sight line of the patient is obtained under a satisfactory measurement environment.
