Title
(EN) PIXEL PROCESSING CIRCUITRY
(FR) CIRCUIT DE TRAITEMENT DE PIXELS
Abstract
(EN)
The invention concerns a method of processing pixel values comprising: during a first read phase, generating a first digital value as a function of pixel values by controlling, based on first and second control signals and a first set of increment rates, the rate that a first counter (220-i) is incremented; and during a second read phase, generating a second digital value as a function of pixel values by controlling, based on first and second control signals and a second set of increment rates, the rate that said first counter (220-i) is incremented, the first and second sets of increment rates each defining an increment rate for each of a plurality of states of the first and second control signals, wherein said first set of increment rates is different from said second set of increment rates.

L'invention concerne un procédé de traitement de valeurs de pixels comprenant l'étape suivante : pendant une première phase de lecture, génération d'une première valeur numérique en fonction de valeurs de pixels par réglage, sur la base des premier et second signaux de commande et d'un premier ensemble de cadences d'incrémentation, la cadence à laquelle un premier compteur (220-i) est incrémenté; et, pendant une seconde phase de lecture, génération d'une deuxième valeur numérique en fonction des valeurs de pixel par réglage, sur la base des premier et second signaux de commande et d'un second ensemble de cadences d'incrémentation, la cadence à laquelle ledit premier compteur (220-i) est incrémenté, les premier et second ensembles de cadences d'incrémentation définissant chacun une cadence d'incrémentation pour chacun d'une pluralité d'états des premier et deuxième signaux de commande, ledit premier ensemble de cadences d'incrémentation étant différent dudit deuxième ensemble de cadences d'incrémentation.
