Canon is a leading provider of consumer, business-to-business, and industrial digital imaging solutions.
An optical zoom is made to bring you closer to your subject, without you having to move. Zooms are constructed to allow a continuously variable focal length, without disturbing focus. To achieve this, the optical zoom uses a combination of lenses that magnify the image prior to being registered at high resolution by the sensor. While the digital zoom only changes the presentation of existing data, with the optical zoom the data collected by the sensor is actually augmented. Optical zooms are superior to digital zooms, and is utilized on all PowerShot digital cameras.

Personal Computer Memory Card International Association card. PCMCIA cards are about the size of a credit card and these PC Cards have been developed to be a standard for hardware capability expanding devices. Cards used in digital cameras offer removable storage and an easy way to transfer photos from the camera to a notebook or desktop PC.

The PICT format was originally developed by Apple Computer in the mid-1980s. The PICT format supports RGB files with a single alpha channel, and indexed-color, grayscale, and Bitmap files without alpha channels. The PICT format is especially effective at compressing images with large areas of solid color

Joint Photographic Experts Group, *.jpg. The de facto standard for image compression in digital imaging devices. JPEG is a lossy compression technique, capable of reducing digital images files to about 5% of their normal size. This is one of the reasons you can get as many images into your PowerShot digital camera as you can. The results in decompression of the files can cause "blockiness," the " jaggies," or "pixelization" in certain digital images. The greater the compression level the more pixelization or "blockiness" that will occur. The greater the pixel count, the less pixelization that may occur.

Liquid crystal display. The flat screen on many digital cameras that preview photographs that have already been taken. LCDs utilize two sheets of polarizing material with a liquid crystal solution between them. An electric current passed through the liquid causes the crystals to align so that light cannot pass through them. Each crystal, therefore, is like a shutter, either allowing light to pass through or blocking the light.

A bit, which stands for binary digit, is the smallest unit of digital information. Eight bits equals one byte. Digital images are often described by the number of bits used to represent each pixel. i.e. a 1-bit image is monochrome; an 8-bit image supports 256 colours or grayscales; while 24 or 32-bit supports true colour.

Ein neuer externer Bus-standard unterstützt Datenübertragungsraten von 12 Mbit/s USB wird voraussichtlich serielle und parallele Anschlüsse komplett ersetzen. USB eignet sich außerdem besonders gut für High-Speed Plug & Play herunterladen von Bildern von der Digitalkamera direkt auf Ihren PC.
