Método y dispositivo para la detección de la variación temporal de la intensidad luminosa en una matriz de fotosensores

Abstract

[EN] The invention relates to a method and a device for detecting the temporal variation of the light intensity in a matrix of photosensors, comprising a matrix of pixels, a block for the automatic adjustment of the amplification of the photocurrent, and an arbitrating and event-encoding block. Each pixel comprises a photosensor that generates a photocurrent, an adjustable gain current mirror connected to the outlet of the photosensor, a transimpedance amplifier arranged at the outlet of the current mirror, optionally at least one amplification circuit arranged at the outlet of the transimpedance amplifier, and capacitors and detectors of thresholds for determining whether the output voltage exceeds a higher threshold or drops below a lower threshold in order to generate an event in the pixel.

Cada píxel comprende un foto sensor que genera una foto corriente,un espejo de corriente de ganancia ajustable conectado ala salida del foto sensor,un amplificador de transimpedancia colocado a la salida del espejo de corriente,opcionalmente al menos un circuito de amplificación colocado a la salida del amplificador de transimpedancia, condensadores y detectores de umbral para determinar si la tensión de salida sobre pasa un umbral superior o baja por debajo de un umbral inferior para generar un evento en el píxel.
