HS System

The HS System represents a powerful combination of a high sensitivity sensor and high-

performance DIGIC 4 image processing. Designed to provide excellent image quality

and advanced low light performance, the HS System can produce significant

advantages over non-HS System models as listed below:

Improved image quality in all situations – The HS System can capture images

with up to 60% less noise than standard, non-HS System cameras at all ISO

speeds. High ISO sensitivity photos taken with previous cameras exhibited

significant amounts of noise and grainy detail, especially in low light. In

contrast, the HS System can detect and capture more detail and significantly

reduce noise, resulting in more beautiful and true to life shots.

Low Light performance – The HS System truly excels in low light conditions and

is able to preserve the atmosphere of the moment in dark scenes. Common low

light problems such as capturing well exposed subjects against almost

invisible, dark, night-time backgrounds or capturing blurred subjects due to

slower shutter speeds can now easily be conquered. The ISO range is further

extended using Low Light mode, reducing camera shake and subject blur in

even darker conditions. Shooting at a reduced Megapixel resolution, the

camera chooses an ISO speed between 100 and 6400, allowing users to

capture a scene as they see it.

Wider ISO range – The HS System can leverage the excellent performance of its

high and low ISO settings in order to capture the ambience of any scene with

exceptional image quality using up to ISO 3200. When using Smart Auto mode

users can take advantage of an increased ISO range up to ISO 1600 (previous

Automatic modes supported ISO 800 or less), enabling users to take pictures

using available light without having to manually extend the ISO speed.

Dynamic Range – The increased sensitivity of the HS System allows it to

capture a wider dynamic range with greater variation in brightness when

compared to the results of non-HS System models.

High speed functions

High speed functions enable users to capture both fast moving action and scenes that

would otherwise be very difficult to achieve:

Handheld Night Scene – To capture scenes in very dark conditions, the camera

will take a high speed sequence of shots and then combine them into a single

image with the least possible blur and the best possible exposure.

Best Image Selection – Captures a sequence of high speed shots at 3MP

resolution and then automatically selects only the best one to be recorded in

the memory card. The best image is selected according to criteria such as facial

expression or subject movement. That way a user can take advantage of the

camera’s high speed to capture a great shot in a challenging situation, without

wasting time trying to find the best image from the burst before deleting the

unwanted versions.

High-speed Burst mode – Shoots a continuous burst of images every time the

shutter is released, capturing a number of similarly composed images to

ensure you capture fast paced action.

Super Slow Motion Movie – Utilises the strengths of the CMOS sensor to record

VGA resolution footage (640 x 480 pixels) at 120 fps or 320 x 240 pixels at 240

fps. It provides a great way to slow down fast-paced action like sport and can

be used to analyse a golf or tennis swing.

Smart Auto mode

Smart Auto mode is the ultimate automatic shooting mode, which makes use of

multiple Canon developed technologies including Scene Detection, Motion Detection,

Face Detection and Advanced Subject Detection. It allows everyone to obtain the best

result by simply pointing the camera at a subject and pressing the shutter button.

Smart Auto mode uses Scene Detection Technology to determine the shooting scene by

analysing subject brightness, contrast, distance and overall hue. The camera then

selects the most appropriate scene type from 32 variables, applying the best settings

for optimum output. In Smart Auto mode, a colour icon indicating the type of scene

detected and the lighting conditions is shown on the LCD monitor. Smart Auto also

includes enhanced i-Contrast and Smart Flash Exposure, which ensure that brighter or

darker areas are captured in sufficient detail in the final image by suppressing

overexposed highlights and underexposed shadows. This enables any user without any

knowledge of camera settings to take great quality photos.

Advanced Subject Detection

A further feature of Smart Auto mode, Advanced Subject Detection allows the camera to

identify a moving non-human subject, such as a pet, and track it – ensuring it remains in

focus and well-exposed until the shutter is released.

Face Detection Technology

Face Detection Technology makes it easier than ever to produce superb people shots.

This advanced system quickly and accurately detects faces in a scene – then optimises

camera settings so that everyone looks their best. With the ability to detect up to 35

faces in a frame, it’s great for group photos as well as portraits. These cameras include

the following Canon Face Detection Technologies:

Face Detection AF: Sets the focus for the faces in your people shots – not just

the closest subject

Face Detection AE: Optimises exposure for faces in all lighting conditions –

useful for backlit scenes or indoor shooting

Face Detection FE: Guards against washed-out faces when using the camera’s

flash – perfect for close-up shots in restaurants, clubs or other dimly lit

locations

Face Detection WB: Optimises white balance for natural-looking skin tones

which remain true to life regardless of skin colour and lighting conditions

Red-Eye Correction: Automatically eliminates the unwanted effects of flash

photography after the shot is taken. At the touch of a button in playback,

natural-looking eyes can be instantly restored

Smart Flash Exposure (FE)

Canon’s Smart Flash Exposure intelligently controls the power and usage of the

onboard flash to ensure natural results in a variety of conditions. By using the focusing

distance as well as shooting scene information, an optimum balance between the

ambient light of the scene and flash power is achieved. When shooting in very bright

conditions, shadows sometimes appear on a subject’s face – these can be detected by

the camera and flash can be used to eliminate them. When shooting at close distances

overexposure is avoided by effectively sensing how reflective the subject is as well as

reducing the flash power to compensate for the close shooting distance.

Servo AF/AE

When a subject is moving towards or away from the camera and the shutter is half-

pressed, Servo AF/AE will track it continuously – ensuring that the subject is in focus and

well-exposed when the shutter is finally pressed.

Motion Detection Technology

Motion Detection Technology automatically detects motion in the shooting scene. If

movement is detected the camera will increase the ISO sensitivity and shutter speed to

minimise blur and optimise image quality.

Genuine Canon Lens technology

Developed using the same processes and high quality standards employed to

manufacture its range of professional lenses, Canon’s compact cameras benefit greatly

from Canon’s heritage in lens design, capturing sharp, high-resolution images every

time.

The IXUS 220 HS has a 24mm 5x ultra-wide optical zoom with optical Image Stabilizer

for greater versatility when shooting. The wide coverage of the lens allows more of a

scene to be captured – from portraits to panoramic landscapes.

Full HD Movie including Stereo Sound

Full High Definition video at 1080p resolution is recorded at 24 fps with Stereo sound

ready for playback in excellent quality on HD displays.

Miniature Effect in Movie

Miniature Effect can also be applied to movie recording, providing the ability to capture

model-like scenes in 720p resolution. Miniature Effect gradually blurs the top and

bottom, or the left and right, of the scene, emphasising perspective. The user can select

the frame rate the movie is shot at (6fps, 3fps and 1.5fps options available) so that

when the movie plays back it gives the effect of watching a movie of a time-lapse

miniature model.

Dynamic optical Image Stabilizer (Dynamic IS)

Dynamic optical Image Stabilizer is a technology which was initially developed for

Canon video cameras and is now being incorporated into Canon’s

PowerShot SX220 HS, PowerShot SX230 HS, IXUS 310 HS, IXUS 115 HS and

IXUS 220 HS digital still cameras. It is designed to produce steadier video footage by

compensating for low frequency vibrations, such as camera shake generated when

filming whilst walking.

Optical Image Stabilizer

Canon’s highly-effective optical Image Stabilizer (IS) technology prevents image blur by

dramatically reducing the effects of camera shake. In situations where image blur due

to camera shake is more likely – such as in darker conditions or when shooting with the

zoom extended – the optical Image Stabilizer can help images remain sharp through

minute vibration gyros which detect camera movement caused by hand shake. These

signals are processed by a single-chip IS controller, which discriminates between hand

shake and intentional camera movements. Signals are then sent to the IS unit, which

moves one of the lens elements accordingly to re-align the light rays and cancel out the

effects of camera shake. The IXUS 220 HS features a 4-stop IS System which helps

preserve the sharpness of an image without needing to use a tripod for added stability.

Smart Shutter

Smart Shutter mode uses Face Detection Technology to allow users to take both group

shots and self-portraits more easily and in a more relaxed way. The shutter can be

triggered remotely in three different ways:

Smile Detection: Triggers the shutter when the camera detects a smiling face

within the frame

Wink Self-Timer: Triggers the shutter two seconds after the subject in the frame

has winked, removing the need for a remote control

FaceSelf-Timer: Allows perfect group shots or self portraits by automatically

triggering the shutter two seconds after a new face has entered the frame

Tracking AF

To keep focus on subjects in motion, or to help achieve a creative composition,

Tracking AF mode gives photographers the ability to select objects from the centre of

the frame and track them if they move, or if the frame is recomposed.

DIGIC 4 Processor

Canon’s DIGIC 4 (Digital Imaging Core) processor manages all of the camera’s primary

functions to optimise operating efficiency. Advanced image processing algorithms

deliver superb image detail and colour reproduction with accurate white balance and

minimal noise. High-speed processing results in outstanding responsiveness, rapid

auto focus and extended continuous shooting ability.

Creative shooting modes

The new PowerShot SX series and IXUS models feature additional shooting modes that

make it easier to capture high-quality, creative shots. These modes include:

Movie Digest: When set in this mode the camera will film for up to four

seconds before each still shot is taken at VGA resolution. Then it will combine

all the clips captured from the same day into a single movie. This provides

users with a view of the few seconds before every shot was taken, giving an

alternative and fun way to save those moments in a movie.

Movie Digest Playback: Allows the playback of movies shot in Movie Digest by

date. When playing back these movies, it is possible to jump forward or

backward in four second units with designated button operations.

Creative Filters: A choice of filter effects allows users to have fun with their

photography by creating images with greater impact or a different mood:

o

Toy Camera Effect – darkens the edges of the image, as well as carrying

out image processing to increase the differences in contrast of the

overall image, to re-create the effect of an older style or pinhole

camera. Additionally, three effect types can be selected to attach to the

image: Warm, Standard or Cool

o

Monochrome – allows users to shoot in three types of monochromatic

effects: black and white, sepia or blue

o

Miniature Effect – blurs the top and bottom, or left and right edges of

an image to give the subject a scale model-like appearance

o

Fish-eye Effect – mimics the distortion of a fish-eye lens with one of

three levels of strength (weak, medium, strong)

Super Vivid – saturates the colours of an image for an intensely

o

colourful effect

Poster Effect – reduces the levels of colour gradation to give the image

o

the retro feel of vintage posters

Miniature Effect in Movie – gives the effect of a very narrow depth of

o

field making the scene look like a small-scale model. When shooting,

designated portions of the top and bottom (or right and left side in

vertical shooting) of the image are blurred, while the rest of the image

remains in focus

Image Group Playback: High-speed Burst mode (as above) shoots a large

amount of similarly composed images. However, depending on the objective

when viewing, it may not be necessary to play back all of the images. Therefore

images shot in one high-speed burst are grouped, and it is possible to only

display the first frame. This can be set in the playback menu’s group display

setting.
