ABSTRACT:
An eye position detecting apparatus for detecting an eye position in a facial image utilizes a histogram thereof, wherein the facial image contains a plurality of pixels each of which is represented by a grey level value. The eye position detecting apparatus includes a window generator for windowing the facial image, a histogram extractor for extracting a histogram from the windowed facial images, a peak detector for detecting peaks of the histogram and for comparing the number of the peaks with 3, an area calculator for calculating the areas of the histogram for each of the windowed facial images when the number is equal to 3 and a selector for selecting a largest area among the calculated areas and determining the eye position by using largest area.
