Classification: CPC G | IPC G

Claim 0:
1. A calibration device for calibrating detection processing of a line of sight of a user, the calibration device comprising:
a determination unit configured to determine whether an eye of the user is detectable;
an instruction unit configured to instruct the user to look at each of a plurality of positions;
an acquisition unit configured to acquire, for each of the plurality of positions, an image of a face of the user looking at each position; and
a calibration unit configured to calibrate line-of-sight detection processing based on the image of the user's face,
wherein the calibration device can perform
first calibration processing in which the instruction unit gives an instruction to look at each of the plurality of positions by moving the face and the calibration unit calibrates the line-of-sight detection processing based on the image of the face of the user looking at an individual position according to the instruction, and
second calibration processing in which the instruction unit gives an instruction to look at each of the plurality of positions without moving the face and the calibration unit calibrates the line-of-sight detection processing based on the image of the face of the user looking at the individual position according to the instruction, and

the calibration device is configured to
execute both the first calibration processing and the second calibration processing when it is determined by the determination unit that an eye of the user can be detected, and
execute the first calibration processing and cease to execute the second calibration processing when it is determined by the determination unit that an eye of the user cannot be detected.
