Canon is a leading provider of consumer, business-to-business, and industrial digital imaging solutions.
Pronounced "Gooey." Stands for Graphic User Interface. Refers a programme interface that takes advantage of the computer's graphics capabilities to make the program, itself, easier to use. PowerShot software utilises a GUI that is very effective because of its familiarity to popular browsers.

Reduced colour mapping, 8 bit or less. Done to reduce images to their smallest size. Commonly used for images placed on home pages of the Internet. The 256 colour palette are also mapped for best results on the Internet, taking into account the differences between the Windows and Macintosh colour palettes. (Also see GIF, GIF 89a, BMP).
Industry:Consumer electronics
Method used in software to augment the resolution of an image map. The software adds pixels to an image based on the value of surrounding pixels, thereby increasing its resolution. This method can cause artefacting.

A.k.a. pixelization. Term for the stair-stepped appearance of a curved or angled line in digital imaging. The smaller the pixels and the greater their number, the less apparent the "jaggies".

1,024 bytes, written KB, used to refer to size of files, which relates to the amount of information in a file.
Industry:Consumer electronics
Data compression techniques that reduce some detail of a digital image are described as being "lossy." Most video compression techniques utilise lossy compression.

Developed by IBM, microdrives are extremely small hard discs that can fit in a CompactCard memory slot. Two drive capacities will be available 170 MB and 340MB, enabling digital cameras designed to use CompactFlash memory cards to enjoy even larger storage capabilities. All PowerShot digital cameras utilise the CompactFlash image storage format.

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 utilised on all PowerShot digital cameras.
Industry:Consumer electronics
Expression used to indicate that the light sensitive material has been excessively exposed. This can be the result of light that is either too bright, or has been allowed to act for too long. In digital imaging, over-exposure is also referred to as blooming.
