Abstract

La présente invention concerne un générateur de signal de lampe utilisant un mode de non commutation, et un capteur d'image comprenant celui-ci. Un générateur de signal de lampe est décrit dans un aspect de l'invention. Dans un mode de réalisation, le générateur de signal de lampe, qui émet un signal de lampe pour conversion analogique-numérique, comprend: un module de réglage de puissance de référence qui règle une puissance de référence; et un module d'émission de signal de lampe qui charge un élément capacitif préparé au moyen d'une tension de référence, décharge l'élément capacitif, et produit un signal indiquant la progression de la décharge en tant que signal de lampe. Le générateur de signal de lampe de l'invention présente l'avantage d'émettre le signal de lampe en mode non commutation, ce qui élimine radicalement le bruit de commutation.
