The Canon EOS 450D has a EOS integrated cleaning system this is
implemented every time you start upyour camera to remove dust.
A self-cleaning sensor unit creates a short burst of hi frequency
vibrations to shake dust particles off the infared filter, this lasts
for one second but is disabled when taking pictures after start up.
There are two other ways the EOS 450D reduces dust collection and the
makers Canon have managed to reduce the dust generation with
redesigned body cap that prevents dust collection through wear of the cap
itself.
The last way is to repel dust from the low pass filter covering the front
of the cmos sensor this is done by anti static technology to repel dust particles.
The last product to repel dust Canon have developed a
internal dust delete system this maps out were visible dust that landed
on the sensor and developed a software called digital photo
professional software can delete from the image the dust particles
when processed by the software.
