Abstract
(EN)
This imaging device comprises: a light source that emits a plurality of light pulses to be irradiated on to a target section; an image sensor that includes a plurality of pixels and detects a plurality of reflected light pulses that originated in the plurality of light pulses and have returned from the target section; and a control circuit that controls the light source and the image sensor. The control circuit: causes the light source to emit the plurality of light pulses towards the target section; causes the image sensor to detect a component from a first period in each of an n1 number of reflected light pulses among the plurality of reflected light pulses; causes the image sensor to detect a component from a second period in each of an n2 number of reflected light pulses among the plurality of reflected light pulses; and causes the image sensor to execute an operation to detect light an n 3 number of times during a period in which the plurality of light pulses are not irradiated on to the target section. n1 < n2 and n1< n3.

La présente invention concerne un dispositif d’imagerie comprenant : une source de lumière qui émet une pluralité d’impulsions de lumière à rayonner vers une section cible ; un capteur d’image qui comprend une pluralité de pixels et qui détecte une pluralité d’impulsions de lumière reflétée qui provenaient de la pluralité des impulsions de lumière et qui sont revenues de la section cible ; et un circuit de commande qui commande la source de lumière et le capteur d’image. Le circuit de commande : amène la source de lumière à émettre la pluralité des impulsions de lumière vers la section cible ; amène le capteur d’image à détecter un composant d’une première période dans chacun d’un nombre n1 d’impulsions de lumière reflétée parmi la pluralité des impulsions de lumière reflétée ; amène le capteur d’image à détecter un composant à partir d’une seconde période dans chacun d’un nombre n2 d’impulsions de lumière reflétée parmi la pluralité des impulsions de lumière reflétée ; et amène le capteur d’image à exécuter une opération de détection de lumière d’un nombre n3 de fois durant une période dans laquelle la pluralité des impulsions de lumière ne sont pas rayonnées sur la section cible. n1 < n2 et n1 < n3.
