SAFETY PRECAUTIONS
The following precautions should be observed when servicing.
1. Since many parts in the unit have special safety-related characteristics, always use genuine CANON replacement parts.
Especially critical parts in the power circuit block should not be replaced with other makes.
Critical parts are marked with !in the schematic diagrams.
2. When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have been overheated or damaged
by the short circuit.
3. After servicing, see to it that all the protective devices such as insulation barriers, insulation papers shields are properly installed.
4. After servicing, make the following leakage current checks to prevent the customer from being exposed to shock hazards.
4-1 Leakage Current Cold Check
1) Unplug the AC cord and connect a jumper between the two prongs on the plug.
2) Measure the resistance value, with an ohmmeter, between the jumpered AC plug and each exposed metallic cabinet part
on the equipment such as screwheads, connectors, control shafts, etc. When the exposed metallic part has a return path to
the chassis, the reading should be between 1MΩand 5.2MΩ. When the exposed metal does not have a return path to the
chassis, the reading must be ∞.
4-2 Leakage Current Hot Check
1) Plug the AC cord directly into the AC outlet. Do not use an isolation transformer for this check.
2) Connect a 1.5KΩ10 watt resistor, paralleled by 0.15µF capacitor, between each exposed metallic parts on the unit and a
good earth ground such as a water pipe, as shown in the figure below.
3) Use an AC voltmeter, with 1000Ω/volt or more sensitivity, to measure the potential across the resistor.
4) Check all exposed metallic parts of the cover (Cable connection, Handle bracket, metallic cabinet.
Screwheads, Metallic overlays, etc), and measure the voltage at each point.
5) Reverse the AC plug in the AC outlet and repeat each of the above measurements.
6) The potential at any point should not exceed 0.75V RMS.
A leakage current tester (FLUKE MODEL : 8000A equivalent) may be used to make the hot checks.
Leakage current must not exceed 0.5 milliamp.
In case a measurement is outside of the limits specified, there is a possibility of a shock hazard, and corrective action must
be taken before returning the instrument to the customer.

1 Development Background
1-1 Development Objectives
Beginning with the ultra compact 2-megapixel 3x zoom IXY DIGITAL 300 introduced in Spring 2001, followed
in succession by the PowerShot A20/A10 and IXY DIGITAL 200, all four models adopted primary color filters
and the new image engine which provides exceptional color reproduction, and have received high acclaim for
their image quality.
Even the PowerShot A20/A10 has a friendly design intended for a wide range of users, but they are especially
suited to general use because of the high image quality and advanced functions exceptional for their class, and
support for the popular AA-size batteries, which have resulted in very good sales. The PowerShot A20/A10 is
a product for which high-volume sales can be expected, because of the positioning in the mid-price range, so
continuing to maintain a stable share in the market for this class of camera is indispensible to the business
strategy.
The PowerShot A40, with the same basic capabilities as the PowerShot A20, also incorporates advanced
photographic features provided with the PowerShot G2 and PowerShot S40/S30, and further evolves the design
so the above objectives can be achieved with a digital camera having even greater imaging capabilities for the
price. Furthermore, to target those users looking to pay a lower price, the PowerShot A30 with a 1.3-megapixel-
grade CCD (active camera component pixels) will be manufactured as a successor to the PowerShot A10.
1-2 Product Concept
The PowerShot A40/A30 is intended as successor to the basic product concepts of the PowerShot A20/A10,
targeting the first-time digital camera user looking to simply enjoy a digital camera or to minimize expense. Our
design idea is to provide enhanced functionality through the theme of More Basics & Value, by providing “high
image quality,” “advanced features with comfortable operation” rounded out with “conservative design” and
“system accessories and software” as the product concepts.
Also, to promote a new culture of simple printing for digital camera users, the PowerShot A20/A10 supports
the so called Camera Direct {{Direct Print?}} feature that provides easy printing with the CP-10 Card Photo
Printer. The PowerShot A40/A30 will continue the same support, and also be compatible with the CP-100
Photo Printer now under development, which supports A6-size printing for credit-card to postcard size prints.
More Basic & Value
- Movie function with Audio
- Capability of manual functions
- Upgrade for photographing features
- Suport for “new photo-printer”

2 Features
2-1 High Image Quality
zNew image capturing optics brings out high resolution (PS A40)
The PowerShot A40 uses the same CCD as the PowerShot A20, but with its characteristics improved by
partial modification of the image capturing optics, resulting in better resolution than the PowerShot A20.
zHigh-precision white balance (Auto + Five preset positions)
With the PowerShot A40/A30, the whole screen is divided into many blocks from which RAW calculation
data for white balance is collected, to allow precise control.
Also, as with the PowerShot G2/S40/S30, the Fluorescent Lamp preset white balance position is subdivided
into two settings, called Fluorescent Lamp and Fluorescent Lamp H, for a total of five setting positions.
Recently, fluorescent lamps have appeared with a variety of color hues, compose of many high and low color
temperature objects. The single Fluorescent Lamp white balance setting is unable to support all of these
variations. The Fluorescent Lamp position now supports relatively lower color temperatures such as “white”
and “daylight white”, and the Fluorescent Lamp H position supports relatively higher color temperatures such
as “daylight color”. The regular light bulb position is also used for incandescent-colored fluorescent bulbs.
zWide range of ISO-equivalent speed settings (Auto/ISO 50/100/200/400 equivalent)
The PowerShot A40/A30 user can select ISO sensitivity equivalent to film ratings of ISO 50, 100, 200 and
400, just as one would select a file speed for a silver-halide camera according to the photographic conditions.
The low-sensitivity ISO 50 setting is best for still subjects unaffected by a slow shutter, or subjects in a bright
environment where there is no need to worry about camera shake, because of its superior noise characteristics.
On the other hand, while the ISO 400 setting has the disadvantage of lower S/N, it is appropriate for low-light
conditions where a strobe cannot (or should not) be used, or when a fast shutter speed is needed.

2-2Full Features / Operation ease
zColor Effect Modes (Vivid color, Neutral color, Soft, Sepia and Black & White) are provided
The PowerShot A40/A30 includes the same color modes as the PowerShot G2 and PowerShot S40/S30, plus
an additional Soft mode, providing five modes available for selection.
Also, the mode is now selected by a special-purpose (Exposure Control, WB, Color Effect, Single Image
Erase) button instead of the mode dial, so color effects can be used in ways that were impossible before,
such as in photostitching or movies. Table 2-2 shows the contents and effects.
zDirect print function for dedicated printers (CP-10/CP-100)
The PowerShot A40/A30 includes the Direct Print function, which provides high quality prints by connecting the
camera via dedicated cable to Canon’s
CP-10 Card Photo Printer or CP-100
Photo Printer, newly developed for
postcard-size prints.
All printing operations are performed
by the camera controls, including selection
of border/borderless and adjusting the
print area to match the image aspect ratio
when creating borderless credit-card-size
prints. The print area can be aligned
relative to three sides. Credit-card-size
printing capabilities include full-size label
prints or eight copies of the same image
on one sticker sheet.
The new image engine in the camera
provides the high-speed color processing
calculations for printing that are normally
performed by driver software in the PC.
zMovie recording and playback with audio (selectable pixel size from QVGA and Q2VGA )
(It is impossible for PS A30 to record audio)
The PowerShot A30/A40 can record movies in QVGA (320 × 240 pixels) and Q2VGA (160 × 120 pixels)
formats at 20 frames/second (only the PS A40 records sound). Up to ten seconds recording is possible in
QVGA, and up to 30 seconds in Q2VGA format.
The focus, exposure, WB and zoom settings are set at the start of recording, and are used until finished record-
ing. While recording, the available time remaining is displayed on the LCD.
The AVI-format files recorded consist of Motion JPEG image data and monaural WAVE sound data.
* When the remaining capacity of the CF is less than the buffer memory capacity, recording can continue until
the time determined by the remaining capacity of the CF.

zAF Frame (3-point) auto selection (AiAF) and center single-point selection (AF)
The PowerShot A40/A30 incorporates both the 3-point AiAF method in
which the camera automatically determines the proper AF frame from
three measurement points, and the standard AF method that uses a single
center point, so the user can select the best method depending on
photographic conditions.
zSelectable of evaluative metering and spot metering
In the PowerShot A40/A30, a spot metering function has been added
to the averaging light metering method employed by the PowerShot
A20/A10. The averaging method divides the screen into many blocks,
allowing the camera to determine the optimum exposure setting from various complex lighting factors such as
the light exposed in each block, subject position, brightness, background and foreground lighting and reflected
light. Supplementing this method, the spot metering method measures the light only at the center of the field.
z“Macro”,”Snap” and ”Landscape” are available in the focus zone
Added to the PowerShot A40/A30 is a Snapshot mode optimized for snapping pictures of people 1.5 to 2.5
meters from the lens. This mode joins the Macro mode for close-up photography of subjects 16 cm (26 cm in
telephoto) to 76 cm from the lens, and the Distance mode for landscape photography of subjects 5 m or further
from the lens.
These distance ranges minimize the time required for the AF system to determine the correct focal distance.
zShutter speed is allowed from 15 sec. to 1/1500 sec.
The PowerShot A40/A30 provides a 15-second long-exposure shutter speed, the longest level available in this
class of camera (with shutter-speed priority). Combining this speed with the F2.8 aperture setting provides
photos with a maximum of EV 1 (ISO 100 equivalent), permitting photography in dark environments without a
strobe.
Also, with the fastest 1/1500-second shutter speed, fast-moving subjects can be photographed with minimal
blurring.
zEnabling for On/Off selection of AF-assist light
Many of the PowerShot series are equipped with an assist light to ensure proper autofocus when ambient
brightness is below a certain level. However, when photographing animals in a dark environment, they may react
to the AF assist light by running away, preventing the desired photo from being taken in such situations.
The PowerShot A40/A30 therefore includes the capability to turn the AF assist light on and off, so that photos
can be taken without it in situations like the above.
*When the surrounding light level is extremely low, the AF function may be unable to determine the proper
focus. In such cases, the focus is fixed at a specific point.

zEnabling for manual settings (aperture value and shutter speed)
The PowerShot A40/A30 provides the capability for manual exposure settings, in which the user selects the
shutter speed and iris value (2 levels) as desired, so the user can completely override the camera’s automatic
controls. This capability is most suitable in cases that cannot be handled by auto exposure, such as when taking
photos under irregular lighting conditions, such as when photographing fireworks, and for intentional exposure
settings when striving to obtain special effects.
When the strobe is enabled with manual exposure settings, full luminance is provided.
zAF lock function enables fixed focus shooting
The PowerShot A40/A30 allows locking AF by pressing the AF Lock button (Macro/Snap/Distance/ /AF Lock)
when the shutter button is pressed halfway and after the AE/AF processing is finished.
Also, in previous models, the AF Lock setting was canceled after each picture was taken, but in the PowerShot
A40/A30, it remains enabled until certain operations* are performed, making possible continuous photography
with the same focus setting.
* Pressing the AF Lock button again, zooming, LCD off and changing photographic mode
zBuilt-in flash with five flashing modes
The strobe built into the PowerShot A40/A30 can be set to five lighting modes: auto, auto red-eye reduction, on/
off, red-eye reduction on and slow synchro, according to the photographic situation.
zMagnified playback for convinient image confermation (from approx. 2X to 10X zoom)
During playback, the displayed
image can be magnified with
continuous zoom from two to
ten times. Also, by pressing the
SET button when setting
magnification, the magnification
steps in three preset ratios of
2.5, 5 and 10x.
Magnified images can be
scrolled to view a desired region.
zEleven-language international GUI support
The LCD menu on the PowerShot A200/A100 supports
eleven languages, expanding the number of native-language
environments for the camera. The following languages are
supported.
zSelf-timer photography (selectable from 2sec. or 10 sec.)
The PowerShot A40/A30 adds a 2-second selection to the 10-second timer provided previously. The 2-second
setting is useful as a substitute for an external release to avoid camera shake on a tripod mount.
zReset of all settings by one-touch operation
The PowerShot A40/A30 includes a function to return all user settings made on the LCD to their default values.
By pressing the menu button for five seconds, the reset dialog appears, and clicking OK executes the reset.

2-3 Accessories and Software
zTele conversion lens for taking 252 mm (35 mm film format equivalent) tele-photo angle shots
(With bayonet type new conversion lens adapter.)
The zoom lens in the PowerShot A40/A30 performs as the equivalent of a 35- to105-mm lens in a 35-mm film
camera, but the TC-DC52 teleconversion lens has been developed to extend support for longer distance photog-
raphy.
The TC-DC52 expands the lens focal distance by about 2.4x, resulting in the equivalent of a 252-mm lens in a
35-mm film camera (or up to an equivalent of 630 mm with digital zoom on the PowerShot A40, and 504 mm on
the PowerShot A30).
Teleconverters can therefore provide a photographic magnification range of over 10x using only optical magni-
fication: from the equivalent of a 24.5-mm lens in a 35-mm film camera when using the WC-DC52 wide
converter, to the 252-mm equivalent performance with the TC-DC52 teleconverter.
To install the teleconversion lenses, the newly designed LA-DC52N conversion lens adapter is required, but
because a new bayonet attachment system is employed, attaching and removing can be done with one touch, so
operation is greatly improved.
*The optical viewfinder is not usable when a teleconverter is attached, so the LCD must be used instead. Also,
the strobe is not usable because its light is obstructed by the teleconverter.
zWaterproof case good to 30 m underwater (renewal)
The PowerShot A40/A30 fits into the specially designed WP-DC200s Waterproof Case, submersible to 30
meters for diving and snorkeling.
This waterproof case was developed based on the WP-DC200 case for the PowerShot A20/A10, so it can be
used with these models as well.
*We intend to publish information later about the special technologies used in the waterproof case.
zFull featured application softwares
Purchasers of the PowerShot S40/S30 introduced in Autumn 2001 receive various services on the Canon Image
Gateway website established by the cooperation of Canon Inc. and Canon Sales Inc. Through this service,
