A new concept, PowerShot SX100 IS is compact and portable with streamlined
controls. Take it everywhere, because inside is a level of photographic
power that’s truly impressive; 8.0 megapixels ensure deeply detailed

DIGIC III Image Processor
With DIGIC III, your images boast superior quality, the camera operates
at top efficiency and battery life is enhanced. What’s more, DIGIC
III enables Canon’s Face Detection Technology and Red-eye Correction
to give you better, more true-to-life people shots. Simply press the
Shutter Button halfway down, and the camera automatically pinpoints
the faces in the scene and chooses the ideal focus point. The camera
controls exposure settings and flash to keep every face looking bright
and natural. Red eyes can be corrected during playback.

DIGIC III Image Processor
iSAPS Technology is an entirely original scene-recognition
technology developed for digital cameras by Canon. Using an internal
database of thousands of different photos, iSAPS works with the fast
DIGIC III Image Processor to improve focus speed and accuracy, as well
as exposure and white balance.
