ABSTRACT:
An apparatus is provided with an illuminating light source for illuminating a user's eye and an optical system for causing, Purkinje image and an anterior eye part image created by the illumination to be formed on a solid state image pickup element, and is designed such that the influence of extraneous light is mitigated in the output signal of the solid state image pickup element by the use of a polarizing element for selecting the polarization characteristic of the image light received by the solid state image pickup element.
