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 to maximize each pixel's light gathering efficiency that were first seen with the professional EOS-1D Mark III model. 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.
12.2 Megapixel APS-C Size CMOS Sensor
DIGIC 4 Image Processor
The improved DIGIC 4 Image Processor ensures that images are captured, processed and saved with remarkable speed. The EOS Rebel T3 DSLR's new 3:2 multiple aspect ratio, in-camera RAW image processing, creative filters, image resizing and provided S2 and S3 image-recording quality are all possible thanks to the DIGIC 4 Image Processor. With dazzling results, the new DIGIC 4 Image Processor also works to capture and process data of images shot at 12.2 Megapixels at 3.0 fps, as well as 14-bit signal processing for excellent image gradation, enhanced Face Detection Live mode, Full HD video recording, Auto Lighting Optimizer and Lens Peripheral Optimization.
