Résumé

NOVELTY - The method involves generating colored images, where a common complementary metal-oxide semiconductor sensor (7) has multiple sensor elements. A light with different wavelengths is supplied separately for recording color images. A radiation with another wavelength is supplied separately from the light with the wave length for recording a Laser direct imaging signals of the sensor elements.

Capteur photographique

Un capteur photographique est un composant électronique photosensible servant à convertir un rayonnement électromagnétique (UV, visible ou IR) en un signal électrique analogique. Ce signal est ensuite amplifié, puis numérisé par un convertisseur analogique-numérique et enfin traité pour obtenir une . Le capteur est donc le composant de base des appareils photo et des caméras numériques, l'équivalent du film (ou pellicule) en photographie argentique.

Active-pixel sensor

An active-pixel sensor (APS) is an , which was invented by Peter J.W. Noble in 1968, where each pixel sensor unit cell has a photodetector (typically a pinned photodiode) and one or more active transistors. In a metal–oxide–semiconductor (MOS) active-pixel sensor, MOS field-effect transistors (MOSFETs) are used as amplifiers. There are different types of APS, including the early NMOS APS and the now much more common complementary MOS (CMOS) APS, also known as the CMOS sensor.

Digital imaging

Digital imaging or digital image acquisition is the creation of a digital representation of the visual characteristics of an object, such as a physical scene or the interior structure of an object. The term is often assumed to imply or include the , , , printing and display of such images. A key advantage of a , versus an analog image such as a film photograph, is the ability to digitally propagate copies of the original subject indefinitely without any loss of image quality.
