Title
(EN) OPTICAL SENSOR
(FR) CAPTEUR OPTIQUE
(JA) 光センサ
Abstract
(EN) In order to provide an optical sensor capable of accurately detecting the direction of motion of an object to be detected even when ambient light is present, the optical sensor comprises: a light emitting element; a ring divided photodetector element group (RDPD) that is disposed in a ring at the edge of a region which is exposed to reflected light that is the light emitted from the light emitting element reflected off the object to be detected, and that generates a photocurrent by receiving the reflected light; and a gesture circuit that detects the direction of motion of the object to be detected by receiving the photocurrent generated from the photodetector elements contained in the ring divided photodetector element group (RDPD).
(FR) La présente invention concerne un capteur optique capable de détecter avec précision la direction de déplacement d'un objet à détecter même quand une lumière ambiante est présente, le capteur optique comprenant : un élément émetteur de lumière ; un groupe d'éléments photodétecteurs divisé en anneau (RDPD) qui est disposé dans un anneau à la limite d'une région qui est exposée à une lumière réfléchie, laquelle est la lumière émise par l'élément émetteur de lumière réfléchie sur l'objet à détecter, et qui génère un photocourant en recevant la lumière réfléchie ; et un circuit de détection de mouvement qui détecte la direction de déplacement de l'objet à détecter en recevant le photocourant généré par les éléments photodétecteurs contenus dans le groupe d'éléments photodétecteurs divisé en anneau (RDPD).
(JA)  外乱光が存在しても、検知対象物の移動方向を正確に検知可能な光センサを提供するために、発光素子と、その出射光が検知対象物に反射した反射光が入射する領域の端部に環状に配された、当該反射光を受光して光電流を発生する環状分割受光素子群(RDPD)と、環状分割受光素子群(RDPD)に含まれる受光素子から発生した光電流を受けて、検知対象物の移動方向を検知するジェスチャー用回路部とを備えている。
