Active pixel sensor

An active-pixel sensor (APS) is an angel sensor consisting of an chip ambit absolute an arrangement of pixel sensors, anniversary pixel absolute a photodetector and an alive amplifier. There are abounding types of alive pixel sensors including the CMOS APS acclimated a lot of frequently in corpuscle buzz cameras, web cameras and in some DSLRs. Such an angel sensor is produced by a CMOS action (and is appropriately aswell accepted as a CMOS sensor), and has emerged as an another to charge-coupled accessory (CCD) angel sensors

.

The appellation alive pixel sensor is aswell acclimated to accredit to the alone pixel sensor itself, as against to the angel sensor;1 in that case the angel sensor is sometimes alleged an alive pixel sensor imager,2 active-pixel angel sensor,3 or active-pixel-sensor (APS) imager.
