Advanced 14-bit A/S Conversion
|Canon's EOS Digital SLR cameras utilize advanced 14-bit converters to process the output of the imaging sensor. Tonal transitions are almost indiscernible; gradations are incredibly natural with infinitely superior colour fidelity. As EOS Digital SLR cameras record RAW images at 14 bits, the processed 16-bit TIFF images contain the full range of tonal values as captured by the sensor.|
Auto Lighting Optimizer
|The Auto Lighting Optimizer feature in EOS Digital SLR cameras automatically adjusts brightness and contrast levels, allowing captured images to achieve an optimal and balanced exposure. Images with areas of under - or over-exposure can be easily corrected without compromising on inherent shadow and highlight details. The Auto Lighting Optimizer is both an automatic feature as well as adjustable for use in other modes. This feature can be applied in post-processing for RAW mode shots.|
Chromatic Aberration Correction
|Chromatic aberration, more commonly known as colour fringing, happens in digital imaging. This occurs when colours are not focused through the lens at the exact point on the camera's sensor. This issue can be amended with the built-in feature found in certain EOS Digital SLR models performing the correction. EOS Digital SLR cameras come stored with correction data for quite a number of lenses, further relieving photographers of the need to reconfigure settings when they switch lenses.|
The innovative CMOS sensors developed by Canon enable incredibly sharp pictures to be captured yet limit the likelihood of large power consumption. Unnecessary charge transfers are reduced, thus prolonging battery life. DSLR Cameras equipped with CMOS sensors are proven to be highly responsive as the data transfer speeds are increased by the use of multi-channel signal paths.
Canon's CMOS sensor technology speeds up the process of sensors transferring signals to the image processor, as each individual pixel has its own amplifier. Even at high ISO speeds, resolution and quality are not compromised by low-noise performance. A low-pass filter sieves out false colours detected by the CMOS sensor while retaining full detail when processing the image. Various EOS models contain differing numbers of low-pass filter.
EOS Digital SLR models with full-frame sensors do not require a focal length conversion factor. Unlike other digital SLR cameras in the market, EOS full-frame cameras deliver the angle-of-view similar to 35mm film cameras. This unique feature provides greater control over the depth of field essential to creating beautiful portraits and close-up shots with an ideal amount of background blur. At any ISO value, a full-frame CMOS sensor possesses a larger light-gathering area for significantly reduced noise levels.
DIGIC Imaging Processor
| A seamless transition from the capturing stage to recording stage is ensured by the cutting-edge signal processing technologies of the DIGIC Imaging Processor chips. Together with the CMOS sensor, the DIGIC Imaging Processor uses advanced signal processing algorithms and a high-speed DDR-SDRAM buffer to produce a highly responsive DSLR camera. This results in an intuitive shooting experience with undeniably true-to-life image quality.
The fast processing speeds of the DIGIC Imaging Processors has made possible a number of features such as Live Face Detection AF, HD video recording, Auto Lighting Optimizer and Lens Peripheral Illumination Correction.
EOS Integrated Cleaning System
| Designed for unflagging performance even under the harshest shooting conditions, the diligent EOS Integrated Cleaning System takes comprehensive measures to minimise the effects of dust particles on images by removing dust through an effective mechanical method, as well as using the bundled Digital Photo Professional (DPP) software.
Should any dust manage to make it pass the camera's anti-dust measures and fall onto the low-pass filter, it is shaken off using high-frequency ultrasonic vibrations. Every time the camera is powered on or off, this routine is automatically activated. The dust is then trapped on a sticky lining surrounding the filter assembly, and is prevented from ever falling back into the assembly.
For cleaning via software, simply capture an image of a plain white sheet in order to create Dust Delete Data. This data is basically a map of the sensor and where any dust may be located, and can then be appended to every image for the Digital Photo Professional (version 3.2 or later) software to automatically minimize the effects of dust particles.
Highlight Tone Priority
|Highlight Tone Priority deals with images that suffer from loss of detail due to overexposure by cleverly identifying the problem areas. These areas are then fixed by expanding the gradation range within the highlight regions, resulting in subtle image details being preserved with richer and more realistic colours.|
Lens Peripheral Illumination Correction
|This correction feature brightens the edges of an image where light falloff has occurred, thus enhancing image quality. Based on the specific Canon lens used, the Lens Peripheral Illumination Correction data is automatically detected by the camera and applied to JPEG format images. The illumination characteristic and correction data can be loaded manually onto Canon's EOS Utility software and also available in post-processing for RAW images via the DPP (Digital Photo Professional) software.|
