Abstract
(EN) The present technology relates to: a distance measurement sensor with which it is possible to efficiently arrange circuits that realize distance measurement by means of differing distance measurement schemes; a distance measurement system; and an electronic device. The distance measurement sensor comprises: a light emission control circuit that generates a light emission pulse for controlling the light emission timing of emitted light; a pixel modulation unit that performs charge distribution control in a pixel by an indirect ToF scheme; and a TDC that generates a count value corresponding to the time-of-flight of the emitted light by a direct ToF scheme, wherein the light emission control circuit is arranged adjacently to the pixel modulation unit and the TDC. The present technology can be applied to, for example, a distance measurement sensor that measures the distance to a subject.
(FR) La présente invention concerne : un capteur de mesure de distance avec lequel il est possible d'agencer efficacement des circuits qui réalisent une mesure de distance au moyen de différents schémas de mesure de distance ; un système de mesure de distance ; et un dispositif électronique. Le capteur de mesure de distance comprend : un circuit de commande d'émission de lumière qui génère une impulsion d'émission de lumière pour commander la synchronisation d'émission de lumière de la lumière émise ; une unité de modulation de pixel qui effectue une commande de répartition de charge dans un pixel selon un schéma de ToF indirect ; et un TDC qui génère une valeur de comptage correspondant au temps de vol de la lumière émise selon un schéma de ToF direct, le circuit de commande d'émission de lumière étant adjacent à l'unité de modulation de pixel et au TDC. La présente invention peut être appliquée, par exemple, à un capteur de mesure de distance qui mesure une distance par rapport à un sujet.
