Canon’s CMOS (complementary metal oxide semiconductor) sensor capturesimages with exceptional clarity and tonal range, and offers the mostpixels in its class. It offers many of the same new technologies firstseen in Canon’s professional EOS-1D Mark III to maximize each pixel'slight 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 focallength when attached. Canon’s DIGIC III Image Processor dramaticallyenhances image quality and speeds up all camera operations forintuitive operation. It works in concert with the EOS Rebel XS’s sensorto achieve unprecedented levels of performance in all lightingsituations. 
10.1 Megapixel APS-C Size CMOS Sensor DIGIC III Image Processor
Developed to maximize performance between the capture and recordingstages of digital photography, the EOS Rebel XS’s DIGIC III ImageProcessor works hand in hand with Canon’s CMOS sensor to achieve evenhigher levels of performance. The entire electronic system is totallyredesigned, giving the camera its incredible combination of speed andimage quality. Digital noise is significantly reduced in shadow areas,and color reproduction is superior.
