Sensor de imágenes. El objeto de la invención es un sensor de imágenes (100) con muestreo compresivo "on-chip" para la captura, comprensión y transmisión de imágenes completas. Más concretamente, este sensor de imágenes (100) que comprende una matriz de pixeles (5) con filas y columnas, para convertir la luz incidente en una señal eléctrica, un primer circuito, para generar una secuencia pseudo-aleatoria de números binarios que selecciona los pixeles a comprimir, un segundo y un tercer circuito para recibir la señal de selección (4) de cada pixel y generar para cada pixel comprimido una codificación en frecuencia de pulsos del valor del pixel, y un cuarto circuito que recibe la codificación en frecuencia de pulsos del valor del pixel de cada pixel comprimido, para obtener una señal digital comprimida de la imagen completa.

The invention relates to an image sensor (100) with "on-chip" compressive sensing for capturing, understanding and transmitting entire images. More specifically, the invention relates to an image sensor (100) comprising: a pixel matrix (5) with rows and columns, for converting incident light into an electrical signal; a first circuit for generating a pseudo-random sequence of binary numbers, which selects the pixels to be compressed; second and third circuits for receiving the selection signal (4) for each pixel and, for each compressed pixel, generating pulse-frequency coding of the value of the pixel; and a fourth circuit which receives the pulse-frequency coding of the value of the pixel for each compressed pixel, in order to obtain a compressed digital signal for the entire image.
