A layer boundary detector calculates brightness gradients from brightness values in a tomographic image of an anterior ocular segment of a subject's eye, which is taken by optical coherence tomography, in a depth direction of the tomographic image from a cornea to a retina, detect edges b1, b2, b3, and b4 that are larger than a predetermined threshold, and identify a boundary of each layer of the crystalline lens L from positions of the edge b1, b2, b3, and b4.
