Discover the HD difference. With the classically stylish PowerShot SX20 IS, you can produce magnificent HD movies and dazzling photos. Loaded with features, its got a high-powered 20x wide-angle optical zoom with Optical Image Stabilizer, 12.1 megapixels, a big 2.5-inch Vari-Angle LCD, Blink Detection and more.

The PowerShot SX20 IS is equipped with many of the same features as a higher-end camera: an ultra-powerful zoom, eye-popping resolution and advanced picture-improving technology. 12.1 megapixels of resolution gives your photography incomparable depth and ensures that any section of any shot can be enlarged and cropped with no loss in quality when you edit the image even if you choose to print the image. It can create crisp, clear 13 x 19-inch posters.

Since digital cameras were first developed in the late 1980s, sensor resolution has increased continuously every year, and almost every new camera or update of an existing model has featured a more powerful sensor.
However there's a point at which simply adding more megapixels ceases to have any real benefit, and in fact can have a negative effect.
Cramming more photocells onto a tiny compact camera sensor means those photocells have to be smaller, and are therefore less efficient at capturing light, especially at low light levels, leading to reduced dynamic range and more noise at higher ISO settings.

Canons commitment to innovation defines the excitement of the PowerShot SD780 IS Digital ELPH. 12.1-megapixel resolution is more than a number, its your cutting-edge link to the outstanding clarity and quality youve always wanted in your images. Think bold and big, because razor-sharp oversized prints are a breeze.
Get the picture? Its absolutely brilliant.

Pre-PMA 2009: Ricoh has launched the CX1, a CMOS-based zoom compact camera. The CX1 puts a 9 megapixel CMOS sensor in a R10-like body offering a 28-200mm equivalent zoom range but increasing the screen resolution to 920,000 dots (unusually good for a compact camera). The new sensor allows high-speed continuous shooting (up to 120 frames per second at 640x480 pixel resolution), and has a series of additional technologies to boost dynamic range. The first is a multiple exposure mode that effectively produces in-camera HDR images, the second is a system that uses red and blue data to calculate a green value when the green channel over-exposes.
