Title (EN) FOCUS STACKING FOR RETINAL IMAGING
(FR) EMPILEMENT DE FOCALISATION D'IMAGERIE RÉTINIENNE
Abstract:
(EN) A method of imaging an interior of an eye includes illuminating the interior of the eye with one or more beams of light from a light source, and said illuminating is configured to trigger a change to a pupil of the eye. An image sensor captures a sequence of images of light reflected by the interior of the eye during an expected timeframe when a width of the pupil is changing in response to said illuminating. A processing apparatus combines images in the sequence of images to form a composite image having a larger depth of field than a depth of field of each of the images in the sequence of images. The depth of field for each of the images corresponds to the width of the pupil when each of the images is captured.
(FR) Selon la présente invention, un procédé d'imagerie de l'intérieur d'un œil consiste à éclairer l'intérieur de l’œil à l'aide d'un ou de plusieurs faisceaux de lumière émanant d'une source de lumière, ladite opération d'éclairage étant conçue pour provoquer un changement dans une pupille de l’œil. Un capteur d'image capture une séquence d'images de lumière réfléchie par l'intérieur de l’œil pendant un intervalle de temps attendu lorsqu'une largeur de la pupille change en réponse à ladite opération d'éclairage. Un appareil de traitement combine des images dans la séquence d'images pour former une image composite ayant une profondeur de champ plus grande que la profondeur de champ de chacune des images de la séquence d'images. La profondeur de champ de chacune des images correspond à la largeur de la pupille lorsque chacune des images est capturée.
