Disclosed are an ambient light reflection determination apparatus and an ambient light reflection determination method enabling to determine reflection without using an edge and even in a case where luminance of a reflection generating part in eyeglasses is low. In a reflection determination apparatus (100), a luminance histogram calculation section (102) calculates a luminance histogram representing a luminance distribution of an eye area image, a difference calculation section (104) calculates a difference histogram by finding a difference between the two luminance histograms calculated from the two eye area images having different photographing timings, an evaluation value calculation section (105) calculates an evaluation value regarding reflection of ambient light based on the difference histogram and a weight in accordance with luminance, and a reflection determination section (107) determines the reflection of ambient light based on the calculated evaluation value.
