Abstract[English]
In certain embodiments, an ophthalmic system includes a camera system and a computer. The camera system obtains eye images of an eye (that has an eyelid) during an imaging period. The computer system receives the eye images of the eye from the camera system and extracts a column image from each eye image of the eye images to yield column images. Each column image has a respective longitudinal axis substantially parallel to a vertical axis of the eye. Each column image shows at least the eyelid of the eye at a respective time during the imaging period. The computer system generates a time sequence image from the column images. The time sequence image comprises the column images in temporal order and indicates the position of the eyelid at respective times during the imaging period. The computer system outputs a blink analysis output that includes the time sequence image.[French]
Dans certains modes de réalisation, un système ophtalmique comprend un système de caméra et un ordinateur. Le système de caméra obtient des images oculaires d'un œil (qui a une paupière) pendant une période d'imagerie. Le système informatique reçoit les images oculaires de l'œil à partir du système de caméra et extrait une image de colonne de chaque image oculaire des images oculaires pour produire des images de colonne. Chaque image de colonne a un axe longitudinal respectif sensiblement parallèle à un axe vertical de l'œil. Chaque image de colonne représente au moins la paupière de l'œil à un moment respectif pendant la période d'imagerie. Le système informatique génère une image de séquence temporelle à partir des images de colonne. L'image de séquence temporelle comprend les images de colonne dans l'ordre chronologique et indique la position de la paupière à des moments respectifs pendant la période d'imagerie. Le système informatique délivre une sortie d'analyse de clignement qui comprend l'image de séquence temporelle.
