Face image processing apparatus

A face image processing apparatus comprising:

• a first lighting portion comprising a first polarizer which polarizes light in a first direction and a first light emitter which emits, through the first polarizer, infrared light;
• a second lighting portion comprising a second light emitter which emits infrared light;
• an image capturing portion comprising a second polarizer which polarizes light in a second direction perpendicular to the first direction and an image capturing unit which captures images through the second polarizer;
• and
• an image processing portion which detects, as an eye, a hyperbolic shaped pattern or a cross shaped pattern present in a first image but not present in a second image, based on the first image captured by the image capturing portion when the first lighting portion emits the infrared light and the second image captured by the image capturing portion when the second lighting portion emits the infrared light.
