Classification: CPC A  G | IPC A  G

Claim 14:
15. A computer readable recording medium, which is a computer readable recording medium storing a computer program for causing at least one computer to execute a detection process for a position of a corneal reflection image for gaze detection using the gaze detector as claimed in claim 1, wherein:
the computer readable recording medium stores the computer program that causes the at least one computer to execute:
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.
