Inputs and Outputs Notes
LCD Monitor: The Canon PowerShot Digital Elph SD790 IS has a
3.0" low temperature polycrystalline
silicon TFT color LCD monitor featuring approximately 230,000 pixels with
picture coverage. This
extra-durable, high-resolution screen with tough scratch-resistant coating on
the anti-reflective, PureColor LCD II screen offers a crisp, bright, clear picture
to make shooting playback and using the camera's menu functions convenient
even at an angle. The LCD display's
brightness can be manually adjusted. The LCD display
also features an Night Display feature that when shooting in dark conditions, the
camera automatically brightens the LCD monitor to suit the brightness of the
subject, making it easier to frame the subject.
Note: This digital camera does not feature a separate viewfinder.
Image Sensor: For optimal image quality, the camera uses a 1/2.3" CCD image sensor with
approximately 10.3-million total pixels and 10.0-million effective pixels giving
your shots added depth and detail.
DIGIC III Image Processor: The PowerShot
SD790 IS features the DIGIC III Image Processor. The DIGIC III chip gives
you superior image quality, faster image writing to the SD card, more efficiency
to extend battery life, and higher definition for the LCD monitor.
Technology: The iSAPS (Intelligent Scene Analysis based
on Photographic Space) technology uses an internal database of thousands of
photographs to improve focus speed and accuracy, as well as exposure and white
Face Detection Technology: The DIGIC III chip includes Face
Detection Auto Focus/Auto Exposure technology. Face Detection finds all the
faces in the frame and sets the most suitable focus point. Exposure and flash
are controlled to ensure proper illumination of both the faces and the overall
scene, eliminating the common problem of overexposed faces. The PowerShot SD790
IS also offer Face Detection WB (White Balance) which allows the camera to
concentrate upon faces when calculating white balance for the best possible skin
tones. In addition the digital camera features Face Select and Track which lets
you highlight one face among several in a scene, and the camera will then
concentrate on that one person, even as they move around the scene.
Motion Detection Technology: This sophisticated feature
works in the background to instantly evaluate how fast your subject is moving.
Then it automatically selects and sets the optimal exposure and ISO settings to
keep everything looking sharp and clear. So whether you're shooting a bride
walking down the aisle, a ballet recital or even a child's soccer game, you can
relax and shoot with confidence knowing you've got the picture you intended.
camera features a 3.0x optical zoom lens and a 12.0x total digital zoom. You can
select from the following digital zoom settings.
- Standard: enables shooting at zoom
factors of up to 12x with digital and optical zooms combined at a focal
length of 35mm to 420mm
- Off: enables shooting without digital
zoom with a focal length of 35mm to 105mm
- 1.4x: digital zoom is fixed at the
select zoom factor of 1.4x for a focal length of 49mm to 147mm enabling
faster shutter speed and less chance of camera shake
- 2.3x: digital zoom is fixed at the select zoom factor of 2.3x for a focal length of
80mm to 241.5mm enabling
faster shutter speed and less chance of camera shake
Note: The digital zoom cannot be
used when the LCD monitor is turned off, in Date Stamp or Widescreen
Safety Zoom: Based on the number of recording pixels set,
the Safety Zoom feature calculates the maximum zoom factor beyond which image
quality will begin to deteriorate. The digital zoom will then pause at this zoom
factor for a moment until you want to zoom even closer.
|Safety Zoom Factor|
|Large (3648 x 2736)||3x optical|
| Medium 1 (2816
x 2112)||3x optical|
| Medium 2 (2272
x 1704)||4.2x digital|
| Medium 3 (1600 x 1200)||6.8x digital|
|Small (640 x 480)||12x digital|
Image Stabilization: The Image Stabilization function allows you to
minimize the camera shake effect (blurred images) when you shoot distance
subjects that have been magnified or when you shoot in dark conditions without a
flash. The digital camera offers the following Image Stabilization settings.
- Continuous: You can check the effect of the IS mode on image blur
on the camera's LCD monitor since the IS mode runs continually. This makes
it easier to compose images and focus on subjects.
- Shoot Only: IS mode is only activated when the shutter button is
pressed, so subjects will be captured with reduced blur even if their
movements on the LCD monitor are not smooth.
- Panning: This option only stabilizes the effect of up and down
camera motions on the image. This option is recommended for shooting objects
- Off: Image stabilization is not active.
Recording Media:The camera records still images or moving images with stereo audio on SD Memory
Cards, SDHC Memory Cards , MultiMediaCards, MMCplus Cards and HC MMCplus Cards. Still images are recorded in JPEG, and the
movies are recorded in AVI format (Image data: Motion JPEG, Audio data: WAVE
(monaural)). A 32MB SD Memory Card is included with the camera.
Still Image Resolution/Compression: You can choose from the following
still image resolutions: Large (3648 x 2736),
Medium 1 (2816 x 2112 pixels), Medium 2
(2272 x 1704 pixels), Medium 3 (1600 x 1200 pixels), and Small (640 x 480
pixels). You can also select a Date Stamp size (1600 x 1200), and Widescreen (3648
x 2048). For each resolution (except Date Stamp), you can set the compression to Superfine, Fine or

Mode: You can use this mode to
shoot successive frames while the shutter button is fully pressed. The camera
shoots approximately 1.4 shots per second (Large/Fine mode). The shooting
interval varies depending upon the size of image, compression, and whether or
not the flash is used. Images may be recorded in continuous mode
until the SD Memory card is full. A special high speed memory card is
recommended for best results.
AutoFocus Modes: The camera utilizes TTL (through-the-lens)
automatic focusing with three focusing methods:
- Face Detect: camera automatically detects the position
of a face and uses the data to set the focus and exposure while shooting
- AiAF: camera automatically selects between 9 AF frames
to focus on according to the shooting conditions
- Center: camera fixes the AF frame at the center; this
is recommended when the target subject is at the center of the composition
Auto Focus Lock: If it becomes difficult to focus on the
subject due to low contrast to the surroundings, close up and far away subjects
in the same shot, or quickly moving subjects, you can choose to lock the focus
or auto focus on an object at a similar distance, then shoot the picture after
recomposing the shot.
Focusing Range: The camera features the following focus
- Normal: Use this mode when the distance from the end of
the lens to the subject is 12" or greater.
- Macro: Use this mode to shoot close-ups of flowers or
small items. You can shoot a 1.5" x 1.1" area at a minimum focusing distance
of 1.2" when the camera's zoom is set to its wide-angle setting. You can
shoot an image area of 4.3" x 3.2" at a minimum focusing distance of 12"
when the camera's zoom is set to its tele-photo setting.
- Infinity: In Infinity mode the camera can focus from
9.8' to infinity
- Kids&Pets: In this mode the camera can focus from 3.3'
to infinity throughout the wide-angle/telephoto setting
Shooting Modes: The Canon LCD digital camera features the following

optimal pictures by selecting one of the appropriate shooting modes:
- Portrait: blurs the
background and makes the subject stand out
- Night Snapshot: allows you
to take snapshots of people against twilight or dark backgrounds by reducing
the effects of camera shake, even without using a tripod
- Kids & Pets: lets you
capture subjects that move quickly without missing photo opportunities
- Indoor: prevents camera
shake and maintains the subject's true colors when shooting under
fluorescent or tungsten lighting
- Foliage: shoots trees and
leaves in vivid colors
- Snow: shoots without a
blue tinge and without making subjects appear dark against a bright white
- Beach: shoots without
making subjects appear dark near water or sand where reflected sunlight is
- Sunset: allows you to shoot sunsets in vibrant colors
- Fireworks: captures
fireworks in the sky sharply and at optimal exposure
- Aquarium: selects the
optimal ISO speed, white balance and color balance to capture fish and other

mode, but lets you change a specified color to another
- Compact: shoots in 160 x
120 at 15 fps with a maximum clip length of 3 minutes
- Time Elapse: shoots a
single frame shot at intervals of 1 or 2 seconds; when played back, two
hours worth of recorded frames is compressed to 8 or 4 minutes - sound
cannot be recorded in this mode
Metering Modes: You can select from the following metering modes:
Light Metering: used for standard
conditions. The area within the frame is divided into several zones and
light is measured based on subject position, brightness, direct light and
Averaging: averages the exposure from the entire image, but places more
weight on the subject at the center
- Spot: meters
the area within the spot AE point at the center of the LCD monitor
If you are shooting against a bright background or strong backlight, you may
need to correct the exposure so that the subject doesn't come out too dark. You
can set the adjustments from -2 to +2 in 1/3-step increments.
Exposure Setting (AE Lock): You can set
the exposure and focus separately. This is effective when the contrast is too
strong between the subject and background, or when a subject is backlit.

Flash Modes: The PowerShot SD790 IS has a built-in flash.
Using the control dial, you can select Auto (flash fires in low light),
On (flash always fires), or Off (flash doesn't fire). The
built-in flash has a range of 12" to 11' in Wide Angle and 12'' to 6.6' in
Telephoto. In the menu, you can add the following flash
functions when the flash is set to On or Auto:
- Red-Eye Reduction: When activated, the red-eye reduction lamp fires when the flash is used in
dark areas. This reduces the light reflecting back from the eyes, making
them appear red.
- Red-Eye Lamp: The red-eye reduction lamp lights
orange before the flash fires. This feature reduces the effect of light
reflecting back from the eyes and making them appear red.
- Slow-Synchro: The flash timing is adjusted to
slow shutter speeds. This reduces the chance that only the background will
appear dark when a person is photographed against a twilight background or
night scene, or when an interior shot is taken.
Flack Lock: You can lock the camera's flash exposure so that the
exposure settings are correctly set regardless of the composition of your
ISO Speed: The ISO speed can be
set to 80, 100, 200, 400, 800, 1600, Auto, or High ISO Auto to reduce the
effects of camera shake or avoid blurry subject or to turn the flash off when
shooting in a dark area..
Long Shutter Mode: You can set the shutter speed to a slower setting
to make dark subjects appear brighter. During Long Shutter Mode the camera
applies special noise-reduction processing to images shot at shutter speeds
slower than 1.3 seconds, thereby producing high-quality images.
