    摘要： An eye part detecting device has an image input section (21) for acquiring a face image, an eyelid edge labeling section (24) for detecting upper eyelid candidates and lower eyelid candidates which satisfy predetermined conditions for upper eyelids or lower eyelids in the face image, and an eyelid determination section (27) for comparing combinations of the upper and lower eyelid candidates to determine the combination of the upper and lower eyelid candidates whose relation best satisfies a predetermined condition as the upper and lower eyelids. The eyelid edge labeling section (24) classifies the horizontal edges and vertical edges calculated by an edge calculating section (23) into the upper eyelid candidates and the lower eyelid candidates according to a degree of how well the predetermined conditions are satisfied. A lower eyelid candidate evaluating section (26) may be provided for excluding a lower eyelid candidate when it has at least one horizontal edge present in a lateral direction of the lower eyelid candidate. A lower eyelid candidate discriminating section (25) may be provided for discriminating that of the lower eyelid candidates whose vertical edge does not satisfy the predetermined condition as a lower eyelid preliminary candidate.

    摘要： An obstacle detecting portion (11) on a vehicle detects an obstacle behind the vehicle. A CPU (20) detects the direction of the driver's line of sight based on a driver's face image captured by a camera (12). The CPU (20) determines whether the direction of the driver's line of sight directed to mirrors (51L, 51R) reflecting an image of the obstacle behind the vehicle. According to the result of the determination, the CPU (20) sets the level of an alarm to be outputted by warning signal outputting portions (15, 16).

    摘要： A pattern alignment method performs alignment of the comparison source pattern or the comparison target pattern that has been subjected to the angle-scale conversion with the comparison source pattern. Angular deviations and scale factors between the comparison source pattern and the comparison target pattern are computed separately, after angle and scale conversion, the measured template matching is performed. Therefore, parallel-displacement alignment can be made faster and precise alignment is possible. Template matching processing can be minimized, and aligning can be performed precisely and rapidly.
