Technologies Explained
CMOS
Canon’s CMOS technology is one of the company’s key competitive advantages,
with noise reduction circuitry at each pixel site delivering virtually noise-free
images. In comparison with CCD technology, the lower power consumption
characteristics of Canon’s CMOS sensors also contribute to longer battery life.
Signal conversion in Canon’s CMOS sensors is handled by individual amplifiers at
each pixel site. Unnecessary charge transfer operations are avoided, vastly
speeding up the process of getting signal to the image processor. Noise generation
is reduced, power consumption is limited and faster frame rate potential is
increased.
DIGIC
Image data captured by the CMOS sensor is processed by Canon’s purpose-built
DIGIC image processors before being written to the camera's memory card. DIGIC
technology uses advanced image processing algorithms to ensure precise, natural
colours, accurate white balance, and advanced noise reduction. Ultra-fast
processing speeds result in highly responsive camera operation and near-instant
start-up times.
DIGIC chips work with a high speed image buffer – reading, processing,
compressing and writing image data fast enough to keep the buffer clear during
long continuous shooting bursts. And because DIGIC integrates all key processing
functions, power consumption is kept to a minimum.
EOS Integrated Cleaning System
The EOS Integrated Cleaning System combats sensor dust in three important
ways: Reduce, Repel and Remove.
1. Reduce - Internal camera mechanisms are designed to minimise dust
generation. The redesigned body cap prevents dust generation through wear on
the cap itself.
2. Repel - Anti-static technologies, including a special fluorine coating, are applied
to the low-pass filter covering the front of the sensor so as not to attract dust.
3. Remove - A Self-Cleaning Sensor Unit uses hi-frequency vibrations to shake
dust from the infrared filter for a period of approximately one second after each
