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.
2.
Critical parts are marked with ! in the schematic diagrams.
When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have been overheated or damaged
3.
by the short circuit.
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 1MΩ and 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 1.5KΩ 10 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 Concept
1-1 Development Objectives
Canon has marketed the standard compact PowerShot A-series and S-series, the ultra-compact IXY series,
the full-featured PowerShot G-series, and the top-end PowerShot Pro-series. In recent years, our competitors
have concentrated on offering low-cost models to expand their market share as they target low-end user
segments.
Thus, it has become imperative for Canon to offer digital cameras aimed at first-time users and those who
just want have fun with low-cost and easy-to-use digital cameras.
The PowerShot A20 has a 1/2.7-inch, 2.11 megapixel CCD and a newly developed 3x optical zoom lens.
Despite its low price tag, it offers the image quality and features found in high-end models. Much
developmental attention was also given to the camera’s design and economy. The camera exceeds the user’s
expectations of features from such a low-cost model. It thereby targets low-end users. The PowerShot A10,
with a 1.31-megapixel CCD and almost the same features as the A20, will also be marketed at the same time
to target users seeking an even cheaper model.

1-2 Product Concept
“Basic & Good Value” is the PowerShot A20/A10’s product concept. It is for first-time users, those seeking
fun with a digital camera, and users on a budget. It was designed to be easy to use for beginners while
offering a good value for the money.
To set it clearly apart from the competition, the camera was also developed to provide high image quality
and high-end features normally found in more expensive models. It also has a good number of accessories.
This is to attract hard-core users who may want it as a secnd camera.
The small and simple Card Photo Printer CP-10 will also be marketed at the same time. Instead of viewing
images only on a computer screen or TV monitor, you can easily make and view credit card-size prints of the
images. This “easy printing” system may start a new oulture of digital camera printing.

2. Features
2-1 High Image Quality
! Primary color filter and adaptive signal processing for maximum effect
From the PowerShot 600 onward, Canon has employed a complementary color (Cy, Mg, Ye, G) filter as the CCD onchip filter to obtain color. Since the complementary color filter uses light efficiently, it makes the light sensitivity very
good. It thereby helps to improve the SN ratio (especially the luminance).
However, since the camera processes the signal with the luminance signal and
color signals (Cr/Cb), the image signal obtained must have the complementary
colors converted into the primary colors (RGB) by the color matrix circuit.
However, due to the differences in the spectral characteristics of the
complementary color filter and primary color filter, a color conversion error
can occur during the conversion process. This error is prone to decrease the

good image quality. This is because the
resolution and luminance SN ratio will be lower. To compensate for the demerits of the primary color filter, a new signal
processing circuit has been incorporated.
A new digital signal processing IC has been developed and installed in the camera. The adaptive processing technology
employed in the EOS D30 camera has been theoretically reconstructed in the new digital signal processing IC. The new
digital signal processing IC eliminates the false colors created by the non-linear adaptive filter and improves the SN ratio.
The new IR filter also increases the light sensitivity. Thus, the color reproduction quality is very high while the same
resolution and high SN ratio obtained by the complementary color filter are also obtained.

! High-resolution, 1/2.7-inch, 2.11-megapixel CCD (PS A20),
1/2.7-inch, 1.32-megapixel CCD (PS A10)
To enjoy a digital image as a print, the original image must have the number of pixels matching the print size.
Normally, a regular size print requires 1.3 megapixels, a postcard-size print needs 2 megapixels, and a 5x7 in.
print must have 3 megapixels to attain adequate image quality.
Since the PowerShot A20 has a 1/2.7-inch, 2.11-megapixel CCD, it can record a 1600 x 1200 pixel image
which is adequate for a postcard-size print. When the Card Photo Printer CP-10 is used to print out the image,
an image quality of 5.9 lp/mm can be obtained for a credit card-size print. This is comparable to a normal
print from a film negative.
Since the PowerShot A10 has a 1.32-megapixel CCD, the resolution is numerically about 80 percent of the
PowerShot A20’s. Since the CCD chip size of 1/2.7 inches is the same as the PowerShot A20’s chip, the
camera has a high exposure sensitivity compared to 1.3-megapixel digital cameras equipped with a 1/3.6inch CCD.
*Althougt it can achieve 7.9lp/mm(A20)

! High-resolution 3x optical zoom lens (retractable)
The PowerShot A20/A10 is equipped with a 5.4 - 16.2 mm (3x) zoom lens (equivalent to 35 - 105 mm in 35
mm format) suited for a wide range of picture-taking, from landscapes to snapshots. The lens has 9 elements
in 7 groups, including one single-side aspherical element. From the front of the lens, there is group 1 (4
elements), group 2 (3 elements), and group 3 (2 elements). Rear focusing is executed by moving group 3.
The focusing group’s compact configuration makes the lens movement faster and while consuming less
power.
As for the optical performance, the aspherical element is a highly refractive index, glass-molded element to
cope with the PowerShot A20’s Nyquist frequency of 152.7 lp/mm. This effectively suppresses distortion so
that the lens provides high resolution and low distortion.
When the lens is extended, the lens length is 47.3 mm (at the wide-angle end)/46.1 mm (at the telephoto end).
When the lens is retracted, the length shrinks to 28.11 mm to minimize the lens protrusion.
! High-precision white balance (Auto + 4-position*1 preset white balance)
As with previous models, the PowerShot A20/A10 has auto white balance to obtain the optimum color
temperature. It also has a “Preset” setting (Daylight, cloudy, tungsten, fluorescent) to suit the respective light
source’s color temperature. The user can thereby select the suitable white balance setting.
The PowerShot A20/A10’s white balance is controlled by dividing the scene into over a hundred thousand of
blocks*2/*3. The white balance data is collected from each block and computed. Also, the table for deriving
the coefficient (matrix) that determines the RGB values is optimized for each metering. The result is very
high-precision exposure metering.

Although four preset white balance settings are provided, an icon for the Black and White mode is also
displayed alongside the preset white balance icons.

z Intelligent AE for obtaining optimum exposures
Compared to silver-halide film, the CCD’s exposure latitude is narrow. Even a slight exposure error will
eliminate highlight or shadow detail, resulting in lower image quality. To obtain highly precise exposures,
previous digital cameras have used feedback AE, multi-zone metering, meter weighting control, and other
exposure control methods.
To improve the exposure precision even

! Noise reduction function enables high SN ratio
Normally with a CCD, the longer the exposure is, the more noise the image will have. With the PowerShot
A20/A10 noise reduction is executed automatically.
The process of noise reduction is as follows : After the exposure ends, the aperture remains closed and
another exposure is taken at same shutter speed used for the preceding shot. This enables the camera to
capture only the noise factors as data, and these noise factors are removed from the preceding shot. The noise
in image is thereby reduced.
With the PowerShot A20/A10, when the shutter speed is 1/6sec. or lower, noise reduction is executed. With
the PowerShot A10, when the CCD temperature reaches a certain temperature, noise reduction is executed
additionally regardless of the shutter used.
! Superfine mode comparable to incompression image quality
The PowerShot A20/A10 has a Superfine mode that uses a lower compression ratio than with the Fine mode.
The Superfine mode offers an image quality nearly as good as with an incompressed TIFF image. And yet,
the file size is greatly reduced with the JPEG baseline format.
Since the Superfine mode is a non-reversible compression method, you cannot restore the original data
completely. Since the compression ratio is extremely low, there are no block distortions usually found in
JPEG images. The high image quality is more than adequate for business use.
The processing time is also short. Since the image is in the normal JPEG baseline format, you can view it
without a dedicated TWAIN Driver. It is a widely compatible mode.

With a resolution of 300 x 300 dpi, the
Fig. 2-7 Direct printing
CP-10 provides the same image quality
as Digital Printer CD-300 even though it is more compact. It also can apply a protective coating on the print
for better durability.
The print size is the same as a credit card (54 x 86 mm). This size is easy to organize and carry around. There
are various printing options: Standard, multiple (label paper), borderless print, bordered print, date
imprinting.
The printing speed is 56 sec. for a print with borders. This is the fastest in its class.
For direct prints, the camera must be able to execute at high speed the printer’s color processing which is
normally done by the driver in the PC. The camera must have a high-performance processor and the color
processing must be geared for high speed execution.
In the case of the IXY DIGITAL 300, part of the processing is executed by the camera’s digital signal
processing IC at high speed. And the CP-10 is a sublimation printer that obtains high image quality even
with color processing that is simpler than that of inkjet printers.
Since the processing must be executed at high speed, single-dimensional processing is executed instead of
three-dimensional processing. By optimizing the color characteristics of the inks used, the resulting color
reproduction is adequate for practical use.
Figure 2-8 shows the process flow for making a print. The digital signal processing IC executes this process
at high speed until the resizing step. Then the camera executes the sharpness, color conversion, and density
conversion.

z Digital zoom enables the angle of view to vary gradually (PS A20 : 2.5X (Max. 7.5X together with
the optical zoom)) (PS A10 : 2.0X (Max. 6X together with the optical zoom))
As with the PowerShot A20/A10, the IXY DIGITAL 300 has a digital zoom.
The digital zoom in previous models (PowerShot S10 through Pro90 IS) combined an optical zoom and
digital teleconverter. Within the digital zoom range (when the digital teleconverter operates), the CCD’s
reading area becomes limited to the center portion. Therefore, the number of pixels used for the image is
reduced to 1/4 for a 2X magnified image or to 1/16 for a 4X magnified image. This dramatic decrease in
image quality was the disadvantage of digital zoom.
With the PowerShot A20/A10, the lens moves to the telephoto end. Then when it enters the digital zoom
range, the lens remains in the same position while the • PowerShot A20

! Widely available size-AA batteries
(Primary battery: Alkaline)
(Secondary battery: NiCd*, nickel hydride)
To make the camera body more compact, the PowerShot A-series and S-series cameras use a lithium 2CR5
battery or a dedicated, rechargeable Ni-MH battery. The IXY DIGITAL uses a dedicated, rechargeable Liion battery. However, most competing models use size-AA batteries which are favored for their widespread
availability and low price. Users also support that size-AA batteries can be used.
Many audio-video products and toys use size-AA batteries. There is a wide variety of size-AA batteries such
as manganese,* alkaline*, and lithium used as primary batteries. Secondary batteries include NiCd and
NiMH batteries.
The PowerShot A20/A10 uses size-AA batteries because they are widely available and cheap. The camera
can use alkaline battery. And it can use NiCd,

* The PowerShot A20/A10 cannot use manganese batteries.
Alkaline batteries should be used which are Canon’s recommendation.
Ni-Cd batteries are not recommended positively because they have various performances.
! Three-point AiAF for easy focusing
The PowerShot A20/A10 uses the AiAF*1 system already proven in film-based cameras. With three focusing
points, the camera can focus off-center subjects even without prefocusing.
The PowerShot A20/A10’s three focusing points obtain focusing data from
the three respective frames shown in Fig. 2-11. The most reliable focusing
data is identified and then applied. As a general rule, the closest object
covered by a focusing point is deemed as the main subject. So if there are
two off-center subjects and nobody at the center (Fig. 2-12-a) or, if the
main subject is off-center (Fig. 2-12-b) the camera will focus the correct
Fig. 2-11 Focusing frames.
subject.
Fig. 2-12-a
*1
Fig. 2-12-b
Fig. 2-12-c
The PowerShot A20/A10’s AiAF system focuses the closest subject covered by the three focusing
points. Therefore, if there is an object in front of the main subject as shown in Fig. 2-12 or if the camera
is oriented vertically for the shot in Fig. 2-12-a, the camera may focus the wrong subject.

! Real-image optical zoom viewfinder
The PowerShot A20/A10’s optical viewfinder is a real-image viewfinder consisting of an objective lens with
3 elements in 3 groups, a fully reflective prism to bend the light flux compactly, a roof prism to right the
inversed image formed by the objective lens bending the light flux, and an eyepiece lens.
This optical viewfinder is coupled to the lens zooming operation. Thus, the viewfinder image also zooms
during lens zooming. The compensator lens and variator lens in the viewfinder’s objective lens move along
the viewfinder’s optical axis to show the proper viewfinder image matching the image obtained by the lens
zooming.
To make the viewfinder compact, the objective lens has only 3 elements. Each element is aspherical. In
particular, the variator element has an optimum lens shape being aspherical on both sides. It is positioned for
optimum refraction. Also, the viewfinder’s height and depth are kept compact with two prisms whose optical
axes are refracted along the same plane by the reflective surfaces. Moreover, four fully reflective surfaces
(one on the fully reflective prism and three on the roof prism) are used, and only one surface is a vapor
deposition mirror. The inherent light loss is thereby minimized and a flare-cutting diaphragm is strategically
positioned to eliminate unwanted light rays. The result is a bright viewfinder image.
Also, the long eye relief of 16 mm enables even eyeglass wearers to easily see the viewfinder image.
! Shoot at 1.7-sec. intervals
The PowerShot A20/A10 has a new digital signal processing IC which is an improved version of the Canondeveloped digital signal processing IC. It enables a short shooting interval of 1.7 sec.
Also, other time-consuming functions such as camera startup, digital zooming, image playback, magnified
viewing, and image scrolling now perform in a shorter time.
Fig. 2-13 Shutter release time lag and shooting interval.
! Built-in flash range of 4.2 m (wide-angle end), slow-sync speed mode provided
The PowerShot A20/A10’s built-in flash has a large-capacity capacitor and a large flash tube to provide the
highest flash output in this camera class. This extends the flash range to 4.2 m at the wide-angle end.
A slow-sync speed mode is also provided to properly expose a dark background behind a human subject.

! Shutter speeds from 1 sec. to 1/1500 sec.
The PowerShot A20/A10 boasts the fastest shutter speed in its camera class with 1/1500 sec. This shutter
speed can freeze a fast-moving subject quite well. Also, with the f/13.4 aperture (at the telephoto end), the
camera can take pictures of scenes as bright as EV 18. This is suitable for a sunny beach and ski slope.
The slowest shutter speed of 1 sec. and the f/2.7 aperture (at the wide-angle end) enable the camera to
photograph scenes as dark as EV3. This is effective for sunsets and dim indoor lighting without using flash.
! Total of nine image quality modes (Recording pixels x compression ratio).
The PowerShot A20/A10 offers a choice of nine image quality combinations with three pixel modes (Large,
Medium, and Small) and three compression ratios (Superfine, Fine, and Normal).
The user can select the image quality mode that suits the respective purpose.

space-saving CPU found in the IXY DIGITAL.
z Thin, low-temperature polysilicon LCD monitor consuming little power
In previous models, a flat fluorescent tube was used as the LCD backlight. Since flat fluorescent tubes
require a high voltage to light up, an inverter circuit had to be included. This made the backlight unit bulky.
Its high power consumption also required a large battery, making the camera less compact.
Like the IXY DIGITAL, the IXY DIGITAL 300 uses a white LED for the backlight. The white LED
consumes little power and therefore does not require an inverter circuit or a large battery. The result is a
thinner camera. Also, as shown in the figure, the extra space afforded by the backlight unit’s oblique shape is
utilized by the optics. Space is thereby used efficiently.
Also, the LCD unit is a new, highly transparent unit. The lens sheet was made so that the backlight LED’s
light tubes could be reduced from four (on the IXY DIGITAL) to three without the brightness decreasing.
This saved more space and power.

z Space-saving, new four-blade lens cover built-in
Since the PowerShot A20/A10’s lens diameter (front element) is bigger than that of the PowerShot S10/S20
and IXY DIGITAL, the built-in lens cover is proportionately larger. If the same 4-blade lens cover used in
the PowerShot S10/S20 is incorporated in the

a larger radius.
A new 4-blade, built-in lens cover was
therefore developed to save space in the
PowerShot A20/A10.
Although it has four blades like the

! High-performance, red-eye reduction with power-saving LED
For red-eye reduction in flash pictures, the PowerShot A20/A10 has a red-eye reduction lamp in the flash
unit. To reduce the chances of red eye occurring in the human subject, the red-eye reduction lamp lights
before the flash fires. The red-eye reduction lamp is a bright, high-performance, orange LED with low power
consumption.
It can attain the same red-eye reduction effect as the PowerShot S10/S20’s red-eye reduction lamp while
consuming less power.
! Power-saving design enabling 1000 images to be recorded
With an imaging engine consuming little power, an LCD monitor with no backlight, and a lower power
supply voltage, the PowerShot A20/A10 was designed to save power. Also, with size-AA batteries serving as
the power source, the camera can capture 500 images with alkaline batteries*, and 1000 images with NiMH
batteries*.

2-4 Accessory and Software
! Abundant optical accessories (Conversion Lens Adapter required)
• Wide Conversion Lens for taking 24.5mm (35mm film equivalent) wide-angle shots
Wide Conversion Lens WC-DC52 has been newly developed so that the PowerShot A20/A10 can take
wide-angle shots not possible with the 35-105mm (35mm film equivalent) lens.
The WC-DC52 reduces the camera lens focal length to 0.7x which affords a wide-angle effect
equivalent to 24.5mm in the 35mm format. This is unique among cameras in the same class.
Conversion Lens Adapter LA-DC52 is also required.
- When the wide converter is attached, the optical viewfinder cannot be used. The LCD monitor must
be used instead. The flash also cannot be used because it will be obstructed by the wide converter.
• Close-up lenses for close-ups, and 52mm filters
To enable close-ups, close-up lenses (250D 52mm) can be used. Also, 52mm filters can be attached*
to obtain a variety of visual effects. Conversion Lens Adapter LA-DC52 is required to attach a closeup lens or filter to the camera.
- When a filter is attached, the optical viewfinder and built-in flash cannot be used. There are also
filters that may affect the exposure control.
! Waterproof case effective down to 30 m underwater
PowerShot A20/A10’s waterproof case allows you to use the camera at the beach, in wet weather, and
underwater down to 30 meters. Unlike the weather-proof AW-PS100/110 and AW-PS200 cases for previous
models allowing 3-meter underwater use, the IXY DIGITAL 300’s waterproof case enables you to use the
camera for scuba diving.
! Compact power adapter
For the user’s convenience, a power adapter will be marketed along with the PowerShot A20/A10. This
power adapter can also be used with the PowerShot A20/A10 which will be marketed at the same time as the
IXY DIGITAL 300. The power adapter’s output voltage is designed to be within the common voltage range
of both the IXY DIGITAL 300 and PowerShot A20/A10.
Power is supplied to the camera via the DC Coupler DR-500.
! Ni-MH batteries + Charger
For economy-minded users, secondary, rechargeable Ni-MH batteries and a
Canon battery charger will be available for the PowerShot A20/A10.
The battery voltage is 1.2 V, and the capacity is 1600 mAh (min. 1550 mAh).
With the dedicated battery charger, two batteries can be recharged in about
110 min. (TBD), and four batteries can be recharged in about 220 min. (TBD).

! Full-featured application programs
• Easy-to-use ZoomBrowser EX 2.6 (for Windows)/ImageBrowser 1.6 (for Macintosh)
The ZoomBrowser EX (for Windows) and ImageBrowser (for Macintosh) programs marketed at the same
time as the PowerShot S-series cameras were well received. Upgraded versions (ZoomBrowser EX
2.2/ImageBrowser 1.2) of both programs were offered when the IXY DIGITAL came out. For the
PowerShot G1, ZoomBrowser EX 2.4 and ImageBrowser 1.4 have been made compatible with the Canon
BJ-F870PD printer to be marketed in Dec. 2000 (Japan only). When you insert a Compact Flash card into the
printer, the ZoomBrowser EX /ImageBrowser program starts up automatically.
ZoomBrowser EX 2.6 for the PowerShot A20/A10 and IXY DIGITAL 300 is for simple image editing such
as color, brightness, and contrast adjustments and image cropping. It enables on-screen slide shows, DPOF
editing, and e-mail support. It can change the image to the required size and compression ratio (image
quality) to attain the desired file size. The e-mail program starts up automatically and the image is attached to
a new message automatically. If the e-mail program does not start up automatically, the resized image is
saved and it can be attached to an e-mail message manually.
Like the ZoomBrowser EX 2.6, the
Film size
ImageBrowser 1.6 is also a simple imageCompression level
editing program. It can be used for on-screen
slide shows and DPOF editing, and it is also
compatible with e-mail.* Its printing function
has been improved with options enabling you
to print multiple images on one page, change
the order of the images, resize or rotate the
image, and insert text.
You can also use ZoomBrowser EX
2.6/ImageBrowser 1.6 to adjust the image
quality parameters of images captured in the

CHAPTER 2. TECHNICAL DESCRIPTION
2.2.2 Picture Processing
Note: The VIDEO OUT is installed in the A20 model only.
1) The drive pulse of the CCD sensor is created by both clock from DSP and TG that is operated by
sync. signal.
The picture signal by the drive pulse is output from CCD sensor.
The output signal of the CCD picture is converted to the signal processing and the digital data by
the CDS and A/D converter, and is sent to the DSP.
2) The DSP circuit performs the following signal processing.
• Processes the picture data (using the SDRAM).
• Writes and reads the picture data to and from the CF card.
• Outputs the picture data to the CPU.
• Outputs analog video signal to the LCD and VIDEO OUT.
3) The video signal that is supplied form the DSP is controlled by the LCD driver and is displayed
on the LCD. The video amplifier is activated when the video jack is inserted to the video jack
and drives the video signal in 75 Ω.

How to print out the Auto Focus Chart
The large materials such as “Auto Focus Chart” that occupies a page of large size, can be divided into
several smaller pages using “Graphic Select Tool” for printing the entire page.
< Procedures >
1. Select “
Text Select Tool” from the Command Bar and keep pressing it.
Then, select the “
Graphic Select Tool”.
2. Select the desired portion to print. (Drag the cursor on desired area.)
3. Click “Print” of the Menu Bar. Check “Selected Thumbnails/Graphic”, then start printing.
When you check “Fit of Page”, the data can be reduced or enlarged of its printing size so that the
printing size fits the size of paper.*
4. To cancel the printing area, click an arbitrary position on the display.
* Remarks
The “Auto Focus Chart” of the Service Manual that is saved in this CD-ROM, has the colored markings in colors so that the entire page can be divided into print papers (legal-size x 4 pages, A3 size x 3
pages). Operate as follows.
Select “Graphic Select Tool”. Select the 2 markings having the same color to select the first printing
area. Press "Print" to print the first printing area. Perform the above steps 2 and 3. Select another 2
markings having the second color to select the second printing area. Press “Print” to print the second
printing area. Repeat this procedure until the all pages are printed.
