Canon’s CMOS (complementary metal oxide semiconductor) sensor captures images with exceptional clarity and tonal range, and offers the most pixels in its class. It offers many of the same new technologies first seen in Canon’s professional EOS-1D Mark III to maximize each pixel's light gathering efficiency. It’s an APS-C size sensor (22.2 x 14.8mm), and there's an effective 1.6x increase in the lens’s marked focal length when attached. Canon’s DIGIC III Image Processor dramatically enhances image quality and speeds up all camera operations for intuitive operation. It works in concert with the EOS Rebel XS’s sensor to achieve unprecedented levels of performance in all lighting situations.

DIGIC III Image Processor
Developed to maximize performance between the capture and recording stages of digital photography, the EOS Rebel XS’s DIGIC III Image Processor works hand in hand with Canon’s CMOS sensor to achieve even higher levels of performance. The entire electronic system is totally redesigned, giving the camera its incredible combination of speed and image quality. Digital noise is significantly reduced in shadow areas, and color reproduction is superior.
