Canons CMOS Sensor captures images with exceptional clarity and tonal range and offers the most pixels in its class. Canons DIGIC Image Processor dramatically enhances image quality and speeds up all camera operations for intuitive operation. The sensor and processor work in concert with Canons superlative EF and EF-S lenses, forming the ultimate Digital Trinity.
Great images start with great lenses. For many photographers, Canons legendary EF lens history is the reason to choose the EOS System. The EF and EF-S series lenses are a unique blend of the worlds most advanced optical, microelectronic and precision manufacturing technologies. EF lenses are perfected in Canons laboratories, proven in the field and are at the heart of professional photography. EF-S lenses are designed especially for EOS APS-C sensor cameras, providing lightweight, compact design and high value. Canon develops and produces its own CMOS sensors. Unlike CCD sensors, CMOS sensors convert and amplify signals before they are transferred to the image processor, enabling them to produce exceptionally clean image data and reduce power consumption. Data transfer speeds are increased by using multi-channel signal paths that dramatically improve the cameras responsiveness. Canons CMOS sensors incorporate a unique on-chip noise reduction technology to deal with both fixed pattern and random noise. A multi-layer low-pass filter is placed in front of the sensor to isolate false colors that the sensor may detect. Then, the DIGIC Image Processor processes the image to eliminate those colors while retaining full detail. Developed to enhance performance between capturing and recording stages of digital photography, Canon DIGIC chips use advanced signal processing technologies to dramatically augment image quality and deliver a more intuitive, responsive camera. The DIGIC Image Processors work in concert with Canon CMOS sensors to achieve spectacularly high levels of performance. Signal processing algorithms work with the multi-channel signal from the sensor and the high-speed DDR-SDRAM buffer to deliver significantly improved camera response. Power consumption has been further reduced for even longer battery life. Color reproduction, noise reduction in low light situations and reproduction of fine detail have also been significantly improved. In addition, the latest DIGIC 4 Image Processor speeds up all operations to make a number of inventive new features possible, such as Live Face Detection AF, HD video recording, Auto Lighting Optimizer and Lens Peripheral Illumination Correction. Top EOS SLRs such as the EOS 7D and EOS-1D Mark IV feature two DIGIC Image Processors for an even greater level of quality and power.
