Claim 8:
9. A method for detecting a corneal reflection image position, which is a method for detecting the corneal reflection image position for gaze detection using the gaze detector as claimed in claim 1, the method comprising:
a step of receiving the imaged image and a pupil center position;
a step of setting a search area in a vicinity of the pupil center position;
a step of scanning pixels in the search area one after another;
a step of determining whether a scanning result becomes a maximum value of brightness;
a step of adopting a value of the brightness as the maximum value if it is determined that a dynamic range of brightness is equal to or greater than a threshold; and
a step of outputting a position of a pixel which denotes the maximum value and has a shortest distance from the pupil center as the corneal reflection image position.
