Abstract
An image processing device 1X mainly includes a convergence measurement means 15X, a determination means 16X, and a pupil measurement means 17X. The convergence measurement means 15X is configured to measure a degree of convergence of a subject after eye opening, based on an image obtained by capturing the subject who has performed the eye opening after eye closing. The determination means 16X is configured to determine presence or absence of a focus change of the subject, based on the degree of convergence. The pupil measurement means 17X is configured to measure a pupil of the subject based on the image obtained by capturing the subject, upon determining the absence of the focus change.
Claims15
An image processing device comprising:
- at least one memory configured to store instructions;
- and
- at least one processor configured to execute the instructions to:
- measure a degree of convergence of a subject after eye opening, based on an image obtained by capturing the subject who has performed the eye opening after eye closing;
- determine presence or absence of a focus change of the subject, based on the degree of convergence;
- and
- measure a pupil of the subject based on the image obtained by capturing the subject, upon determining the absence of the focus change.
An image processing method to be executed by a computer, the method comprising:
- measuring a degree of convergence of a subject after eye opening, based on an image obtained by capturing the subject who has performed the eye opening after eye closing;
- determining presence or absence of a focus change of the subject, based on the degree of convergence;
- and
- measuring a pupil of the subject based on the image obtained by capturing the subject, upon determining the absence of the focus change.
A non-transitory computer readable storage medium storing a program for causing a computer to perform a process comprising:
- measuring a degree of convergence of a subject after eye opening, based on an image obtained by capturing the subject who has performed the eye opening after eye closing;
- determining presence or absence of a focus change of the subject, based on the degree of convergence;
- and
- measuring a pupil of the subject based on the image obtained by capturing the subject, upon determining the absence of the focus change.
