Title

(EN) CONDITIONAL-RESET, MULTI-BIT READ-OUT IMAGE SENSOR

(FR) CAPTEUR D'IMAGES À LECTURE MULTI-BITS À REMISE À ZÉRO CONDITIONNELLE

Abstract

(EN) An image sensor architecture with multi-bit sampling is implemented within an image sensor system. A pixel signal produced in response to light incident upon a photosensitive element is converted to a multiple-bit digital value representative of the pixel signal. If the pixel signal exceeds a sampling threshold, the photosensitive element is reset. During an image capture period, digital values associated with pixel signals that exceed a sampling threshold are accumulated into image data.

(FR) On a réalisé une architecture de capteurs d'images à échantillonnage multi-bits dans un système de capteurs d'images. Un signal de pixel produit en réponse à la lumière qui tombe sur un élément photosensible est converti en une valeur numérique à bits multiples représentative du signal de pixel. Si le signal de pixel dépasse un seuil d'échantillonnage, l'élément photosensible est réinitialisé. Pendant une période de capture d'image, les valeurs numériques associées aux signaux de pixel qui dépassent un seuil d'échantillonnage sont accumulées dans des données d'image.
