(FR) DISPOSITIF ÉLECTRONIQUE ET PROCÉDÉ PERMETTANT DE GÉNÉRER UNE IMAGE PAR SYNTHÈSE DE LA DATE ACQUISE À L'AIDE D'UNE PLURALITÉ DE PIXELS COMPRENANT DES DURÉES DE RÉCEPTION DE LUMIÈRE DIFFÉRENTES
Abstract
(EN)
An electronic device is provided that includes an image sensor of first pixels receiving light for a first duration and second pixels receiving light for a shorter second duration, and a processor to acquire first and second raw data including first long pixel values through the first pixels and first short pixel values through the second pixels, second long pixel values through the first pixels and second short pixel values through the second pixels, and third raw data based on the first and second raw data. The third raw data includes third long pixel values and third short pixel values, and each of the third long pixel values is an average value of a first and a second long pixel value and each of the third short pixel values is a value obtained by gamma correcting a sum of a first and a second short pixel value.

L'invention concerne un dispositif électronique qui comprend un capteur d'image de premiers pixels recevant de la lumière pour une première durée et de seconds pixels recevant de la lumière pendant une seconde durée plus courte, et un processeur pour acquérir des premières et secondes données brutes comprenant des premières valeurs de pixels longues à travers les premiers pixels et des premières valeurs de pixels courtes à travers les seconds pixels, des secondes valeurs de pixels longues à travers les premiers pixels et des secondes valeurs de pixels courtes à travers des secondes pixels, et des troisièmes données brutes sur la base des premières et secondes données brutes. Les troisièmes données brutes comprennent des troisièmes valeurs de pixels longues et des troisièmes valeurs de pixels courtes, et chacune des troisièmes valeurs de pixels longues est une valeur moyenne d'une première et d'une seconde valeur de pixels longues et chacune des troisièmes valeurs de pixels courtes est une valeur obtenue par correction gamma d'une somme d'une première et d'une seconde valeur de pixels courtes.
