Summary:A face feature point detection apparatus (1) includes an image capturing device (2), an edge calculating unit (23) calculating edge values indicating a luminance change in a direction, and a detection target determining unit (14) scanning an edge image, which is created by arranging the edge values for corresponding pixels based on pixel arrangement of the face image, with an image window being an aggregation of selected pixels formed in a predetermined shape, the detection target determining unit (14) determining a position of the image window having a largest weighted sum of weighted sums to be a detection position where a detection target is present, providing that the weighted sum is calculated by multiplying the edge value which corresponds to each pixel in the image window by a predetermined value defined on a per-pixel basis and adding up all products of the edge value and the predetertxiined value.
