EYEBLINK MEASUREMENT METHOD, EYEBLINK MEASUREMENT APPARATUS, AND NON-TRANSITORY COMPUTER-READABLE MEDIUM |
| 摘要 |
An eyeblink measurement method includes a step of detecting reflected light from a part including a target person's eyelid and eye and outputting an image signal of the reflected light, using a photodetector, a step of calculating a position of a corneal reflected light produced on the eye in the part and a position of the eyelid in the part based on the image signal, a step of correcting the position of the eyelid based on the position of the corneal reflected light, and a step of calculating a feature amount regarding blinking based on a temporal change in the corrected position of the eyelid. |

1. An eyeblink measurement method comprising:
detecting light from a part including a target person's eyelid and eye and outputting a detection signal of the light, using a photodetector; calculating a position of a corneal reflected light produced on the eye in the part and a position of the eyelid in the part based on the detection signal; correcting the position of the eyelid based on the position of the corneal reflected light; and calculating a feature amount regarding blinking based on a temporal change in the corrected position of the eyelid. |
