Integrated circuit for the digital tuning of temporal contrast in image sensors

Abstract

[ES] Comprende al menos un píxel activo digital que tiene un sensor óptico que genera una corriente Isens en función de una potencia de iluminación, un filtro paso-alto sintonizable por corriente que genera una corriente efectiva Ieff a partir de la corriente Isens y un lazo de enganche de fase que genera una corriente Itune a partir de una señal de frecuencia ftune generada por unas señales digitales externas de control, siendo la corriente Itune la corriente de sintonización del filtro paso-alto sintonizable

[EN] The invention comprises at least one digital active pixel including: an optical sensor which generates a current Isens as a function of an illumination power, a current-tunable high-pass filter which generates an effective current Ieff from the Isens current, and a phase-locked loop which generates a current Itune from a frequency signal ftune generated by external digital control signals, the Itune current being the tuning current of the tunable high-pass filter.
