==LINE-OF-SIGHT DETECTING APPARATUS, IMAGE PICKUP APPARATUS, LINE-OF-SIGHT DETECTING METHOD, AND STORAGE MEDIUM - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18467257 titled 'LINE-OF-SIGHT DETECTING APPARATUS, IMAGE PICKUP APPARATUS, LINE-OF-SIGHT DETECTING METHOD, AND STORAGE MEDIUM

==Simplified Explanation==

The abstract describes a line-of-sight detecting apparatus that acquires an estimated gaze point position of a user on a display element, performs calibration to reduce the difference between the estimated gaze point position and the actual gaze point position of the user, and determines whether to perform the calibration again based on changes in pupil diameter. The user is notified if recalibration is needed and the process is repeated if instructed by the user.

* Processor acquires estimated gaze point position based on eyeball image
* Calibration is performed to reduce difference between estimated and actual gaze point positions
* Recalibration is determined based on changes in pupil diameter
* User is notified if recalibration is needed
* Recalibration is performed again if instructed by the user

==Original Abstract Submitted==

A line-of-sight detecting apparatus includes a processor configured to acquire an estimated gaze point position of a user on a display element based on an eyeball image, perform calibration for the estimated gaze point position to reduce a difference between the estimated gaze point position and an actual gaze point position of the user, determine whether or not the calibration is to be performed again based on a difference between a first pupil diameter of the user when the calibration was performed and a second pupil diameter of the user when the estimated gaze point position was acquired based on an eyeball image acquired after the calibration, notify the user of information about performing again the calibration in a case where it is determined that the calibration is to be performed again, and perform again the calibration in a case where it is determined that the user has instructed to perform again the calibration according to notified information.
