Claim:
1. A corneal endothelial cell photographing apparatus for photographing endothelial cells of a cornea of an examinee's eye, comprising: a cornea photographing optical system including an imaging device that projects light from a photographing light source toward the cornea of the examinee's eye and photographs the corneal endothelial cells of the examinee's eye through the imaging device; a light projecting optical system that projects detection light in a first oblique direction to the cornea of the examinee's eye to detect a focus state of the cornea photographing optical system with respect to the cornea of the examinee's eye; a detecting optical system including a detector in which a plurality of pixels are arranged, the detecting optical system receiving, through the detector, in a second oblique direction opposite to the first oblique direction, corneal reflection light resulting from the detection light and including reflection light reflected from the corneal endothelium, and detecting an intensity distribution of the corneal reflection light in a depth direction of the cornea; and a controller that:
