Canon is a leading provider of consumer, business-to-business, and industrial digital imaging solutions.
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
One or more pieces of glass, specially shaped, arranged to bring together rays of light so they can be recorded on film or paper.
Industry:Consumer electronics
Data compression techniques that reduce some detail of a digital image are described as being "lossy." Most video compression techniques utilize lossy compression.

Developed by IBM, microdrives are extremely small hard disks 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 utilize 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 utilized on all PowerShot digital cameras.

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.
Industry:Consumer electronics
The difference between the image seen by a viewing system and that recorded by the sensor or the film. As subjects move closer to the lens, the variance increases. Only through the lens (TTL) viewing systems avoid parallax error.
