Claim One:
1. An eye part detection apparatus comprising: an imaging section configured to input an image of a face captured for each specific time; and a data processing section including a memory and a calculation unit including a unit configured to extract an eye search region on the basis of feature points including a nose from the image; a unit configured to correlate the eye search region at a first time with the eye search region at a second time on the basis of comparison between positions of the feature points at the first time and positions of the feature points at the second time; and a unit configured to determine eye part regions from the eye search regions at the first and second times on the basis of the correlated eye search regions at the first and second times; wherein the unit configured to determine eye part regions includes a difference image creation unit configured to calculate a luminance difference value for respective correlated pixels of the eye search region at the first time and the eye search region at the second time.
