Abstract
(EN) [Problem] The present disclosure addresses the problem of providing an imaging device and an imaging method which make it possible to generate a DVS image and a grayscale image more quickly. [Solution] An imaging device comprising: a pixel array unit which includes a plurality of DVS pixels that output first luminance signals corresponding to light intensity and a plurality of grayscale pixels that output second luminance signals corresponding to light intensity; a detection circuit which outputs a detection signal indicative of occurrence of an address event when the first luminance signals from the respective plurality of DVS pixels exceed a predetermined threshold; a first reading unit which reads the first luminance signals from the plurality of DVS pixels and converts the first luminance signals into digital data; a second reading unit which reads the second luminance signals from the plurality of grayscale pixels and converts the second luminance signals into digital data; and a control circuit which controls the first reading unit and the second reading unit.
(FR) Le problème à résoudre dans le cadre de la présente invention consiste à fournir un dispositif d'imagerie et un procédé d'imagerie qui permettent de générer plus rapidement une image DVS et une image en niveaux de gris. La solution selon l'invention porte sur un dispositif d'imagerie comprenant : une unité de réseau de pixels qui comprend une pluralité de pixels DVS qui émettent des premiers signaux de luminance correspondant à l'intensité lumineuse et une pluralité de pixels d'échelle de gris qui émettent des seconds signaux de luminance correspondant à l'intensité lumineuse; un circuit de détection qui émet un signal de détection indiquant l'apparition d'un événement d'adresse lorsque les premiers signaux de luminance provenant de la pluralité respective de pixels DVS dépassent un seuil prédéterminé; une première unité de lecture qui lit les premiers signaux de luminance à partir de la pluralité de pixels DVS et qui convertit les premiers signaux de luminance en données numériques; une seconde unité de lecture qui lit les seconds signaux de luminance à partir de la pluralité de pixels d'échelle de gris et qui convertit les seconds signaux de luminance en données numériques; et un circuit de commande qui commande la première unité de lecture et la seconde unité de lecture.
