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).

Face Detection AF finds faces, tracks them as you

frame your shot, then delivers perfect focus.

Face Detection AE makes all your group shots

better by concentrating exposure on your subjects’

faces, not their clothes or the background.

Face Detection FE adjusts the flash exposure

based on the location of the faces in the frame.

Face Detection WB

detects the faces in the shot

and concentrates auto white balance on them,

for the best possible skin tones.

Face Selector AF lets you focus on a specific face.

The selected face is double-framed and

tracked as it moves in the frame. There

is a dedicated Face Selector Button

for

selected models. Some models even

allow quick face selection via touch screen.

OPTICAL IMAGE STABILIZER*

Camera shake often blurs

images in low light and at

long focal lengths.

Canon’s Optical Image

Stabilizer technology

corrects 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

PowerShot

cameras so

compact.

≥ IMAGE PROCESSOR

Renowned for their superb 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, accelerates

processing speed, greatly

enhancing picture quality,

improving noise reduction,

and extending battery life.

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.

HIGH SENSITIVITY SYSTEM*

Canon’s High Sensitivity System (PowerShot

G11 and PowerShot S90) is dramatically

more sensitive than previous CCDs with the

same number of megapixels. Working in concert

with Canon’s DIGIC 4 Image Processor and

higher ISO speeds, Canon created the system

to reduce noise, expand the dynamic range

and deliver images with a new level of clarity

and depth.

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.
