Title (EN) REAL-TIME AUTOFOCUS FOCUSING ALGORITHM
(FR) ALGORITHME DE MISE AU POINT AUTOMATIQUE EN TEMPS RÉEL
Abstract:
(EN) A digital scanning apparatus is provided that includes imaging and focusing sensors and a processor to analyze the image data captured by the imaging and focusing sensors and adjust the focus of the scanning apparatus in real time during a scanning operation. The individual pixels of the imaging sensor are all in the same image plane with respect to the optical path of the digital scanning apparatus. The individual pixels of the focusing sensor are each in a different image plane with respect to the optical path, and one pixel of the focusing sensor is on the same image plane as the image sensor. The processor analyzes image data from the imaging sensor and the focusing sensor and determines a distance and direction to adjust the relative position of an objective lens and a stage of the digital scanning apparatus to achieve optimal focus during the scanning operation.
(FR) L'invention concerne un appareil de balayage numérique qui comprend des capteurs d'imagerie et de mise au point, et un processeur pour analyser les données d'image capturées par les capteurs d'imagerie et de mise au point et pour régler la mise au point de l'appareil de balayage en temps réel pendant une opération de balayage. Les pixels individuels du capteur d'imagerie se trouvent tous dans le même plan d'image par rapport au trajet optique de l'appareil de balayage numérique. Les pixels individuels du capteur de mise au point se trouvent chacun dans un plan d'image différent par rapport au trajet optique, et un pixel du capteur de mise au point se trouve sur le même plan d'image que le capteur d'image. Le processeur analyse des données d'image provenant du capteur d'imagerie et du capteur de mise au point et détermine une distance et une direction pour régler la position relative d'une lentille d'objectif et d'un étage de l'appareil de balayage numérique afin d'obtenir une mise au point optimale pendant l'opération de balayage.
