IMAGE PROCESSOR

Renowned for their superior picture quality,

responsive handling, extended battery life and

fast processing speed, DIGIC Image processors

have set the standard for functionality and

performance since their ground-breaking

introduction in 1999. The latest advance in

this distinguished series, the DIGIC 4 Image

Processor, greatly enhances picture quality

and accelerates

processing speeds

for noise reduction

which gives you

better image quality

at higher ISO speeds.

iSAPS TECHNOLOGY

PowerShot cameras automatically find the optimal

settings for Autofocus, Auto Exposure and Auto

White Balance systems. How? iSAPS (Intelligent

Scene Analysis based on Photographic Space)

technology. iSAPS combines advanced prediction

algorithms with statistical frequencies for key

factors based on Canon's over 70 years of

accumulated data. Effortlessly and in any situation,

you'll get the sharp focus and proper exposure

that turn good images into great ones.

INTELLIGENT ORIENTATION

SENSOR

PowerShot cameras automatically sense

whether a picture is being taken horizontally

or vertically. The camera's Autofocus, Auto

Exposure and Auto White Balance systems use

the information to achieve a level of image

quality not possible with less sophisticated

cameras. Moreover, pictures are properly

oriented during playback, whether on the

camera's screen or a computer monitor.

NOISE REDUCTION

Experienced photographers know that high ISO

speeds can coincide with increased levels of

noise: aberrant or stray signals that degrade

image quality. With Canon's exclusive DIGIC 4

Image Processor, there is no need for compromise.

DIGIC 4 offers a major boost in noise reduction

signal processing to compensate for the higher

ISO settings it enables.

RAW MODE*

The RAW mode lets you shoot images without

the camera processing them in any way. RAW

images can be processed in your computer,

using Canon's DPP (Digital Photo Professional)

software. Creative control is completely in your

hands as you adjust a wide range of variables to

produce exactly the final image you want.

Optical Technology

OPTICAL IMAGE STABILIZER*

Camera shake often blurs

images in low light and at

long focal lengths.

Canon's Optical Image

Stabilizer technology cor-

rects camera shake so

you can achieve excellent

quality images in many

difficult situations

— outdoors at dusk,

inside without a flash,

even at the end of the zoom

range without a tripod. The sophisticated

system detects camera shake and optically

counters the movement, effectively canceling

unwanted lens movement and vibration.

Because it is an optical system, there is none

of the image degradation typical with electronic

image stabilizers.

UA LENS TECHNOLOGY*

The UA lens is a Canon exclusive: a glass-molded

aspherical lens with an ultra-high refractive

index that delivers incredibly bright, clear shots.

Its amazingly small size is a major factor in

keeping the

compact.

FACE DETECTION AF/AE/FE/WB

You always get the shot you want with a camera

equipped with the DIGIC III or DIGIC 4 Image

Processors featuring Face Detection Technology.

When the shutter button is pressed halfway,

the camera finds the face or faces in the frame

to ensure excellent focus and proper illumination

of both the face(s) and the overall scene.

The system also adjusts the flash for the location

of the face(s).
