Patent ID: 7369687

Claim:
A method for extracting a face position, comprising the steps of: preparing digital data of a value of each pixel within an object image region including a region of a human face; and extracting in said object image region a position of a Between-the-Eyes candidate point by scanning and filtering process with a Between-the-Eyes detecting filter in which six rectangles are connected, wherein said Between-the-Eyes detecting filter has a width which is substantially as long as the width of the face, said six rectangles are arranged in two in a horizontal direction x three in a vertical direction, and when Sij (1≦i≦2, 1≦j≦3) represents an average value of brightness of pixels in each of said rectangles, said scanning and filtering process extracts pixels satisfying the following equations, S11<S12 and S11<S21 S13<S12 and S13<S23: and extracting a portion of said object image in a prescribed size which has the extracted position of said Between-the-Eyes candidate point at a center, and selecting a true candidate point from said Between-the-Eyes candidate points in accordance with a pattern discriminating process.
