Title (EN) TWO PASS MACRO IMAGE
(FR) MACRO-IMAGE À DEUX PASSAGES
Abstract:
(EN) Two-pass capture of a macro image. In an embodiment, a scanning apparatus comprises a stage, a high-resolution camera, and a lens that provides a field of view, substantially equal in width to a slide width, to the high-resolution camera. The apparatus also comprises a first illumination system for transmission-mode illumination, and a second illumination system for reflection-mode illumination. Processor(s) move the stage in a first direction to capture a first macro image of a specimen during a single pass while the field of view is illuminated by the first illumination system, and move the stage in a second direction to capture a second macro image of the specimen during a single pass while the field of view is illuminated by the second illumination system. The processor(s) identify artifacts in the second macro image, and, based on those artifacts, correct the first macro image to generate a modified first macro image.
(FR) La présente invention concerne une capture en deux passages d'une macro-image. Dans un mode de réalisation, un appareil de balayage comprend un étage, une caméra haute résolution et une lentille qui procure un champ de vision, sensiblement égal en largeur à une largeur de lame, à la caméra haute résolution. L'appareil comprend également un premier système d'éclairage destiné à un éclairage en mode transmission, et un second système d'éclairage destiné à un éclairage en mode réflexion. Un ou plusieurs processeurs déplacent l'étage dans une première direction pour capturer une première macro-image d'un échantillon au cours d'un seul passage pendant que le champ de vision est éclairé par le premier système d'éclairage, et déplacent l'étage dans une seconde direction pour capturer une seconde macro-image de l'échantillon au cours d'un seul passage pendant que le champ de vision est éclairé par le second système d'éclairage. Lesdits processeurs identifient des artéfacts dans la seconde macro-image, et, sur la base de ces artéfacts, corrigent la première macro-image pour former une première macro-image modifiée.
