ICC Profile - The International Colour Consortium, a group that sets standard guidelines for colour management in the imaging world. Click here to read their FAQs about colour management and ICC profiles and the like. Most printers, monitors and scanners as well as digital cameras, usually come with a driver disc for Windows and Mac systems that includes ICC profiles for the particular device. Colour profiles simply let one piece of hardware or software "know" how another device or image created its colours and how they should be interpreted or reproduced.

IEEE-1284 - This is the high-speed bidirectional parallel port specification, used by printers and devices like card readers.

IEEE-1394 - Better known as "FireWire" - it's the new input/output bus used by digital video devices & PCs. For lots of Firewire info go to Adaptec's Firewire web page

iLink - Sony's term for IEE-1394 FireWire data port found on their camcorders.

Image Processing - Capturing and manipulating images in order to enhance or extract information.

Image Resolution - The number of pixels per unit length of image. For example, pixels per inch, pixels per millimeter, or pixels wide.

Image Sensor - A traditional camera exposes a piece of light-sensitive film, digital cameras use an electronic image sensor to gather the image data. See "CCD" and "CMOS" as well as "Interlaced" and "Progressive Scan"

Image Stabilization - An optical or digital system for removing or reducing camera movement in telephoto zoom lenses. Usually found only on extremely long focal length lenses such as the 10X lens on the Sony FD91, FD95, FD97 and CD1000 or the Canon Pro90 or Olympus C-2100UZ, E-100RS.

InfoLITHIUM - Sony's "smart" lithium rechargeable battery pack. It has a chip inside that tells the camera how long (in minutes) it will last at the current discharge rate.

Inkjet - A type of printer that sprays dots of ink onto paper to create the image. Modern inkjet printers now have resolutions of up to 2880dpi and create true photo-quality prints.

Interlaced - Term used to describe an image sensor that gathers its data by first processing the odd lines and then the even lines. See also "Progressive Scan" for the other (preferred) method.

Interpolated - Software programs can enlarge image resolution beyond the actual resolution by adding extra pixels using complex mathematic calculations. See "Resolution" below

Intervalometer - Fancy term for Time-Lapse. Capture an image or series of images at preset intervals automatically.

Interval Recording - Capturing a series of images at preset intervals. Also called time-lapse.

IR - InfraRed (aka IrDA) uses an invisible (to humans) beam of light to either wirelessly control a device or as a method of transferring data from camera to computer (or printer) without cables. Some cameras also employ infrared in the auto focusing system.

ISO - The speed or specific light-sensitivity of a camera is rated by ISO numbers such as 100, 400, etc. The higher the number, the more sensitive it is to light. As with film, the higher speeds usually induce more electronic noise so the image gets grainier. ISO is the abbreviation for International Standards Organization. (In the good old days it was known as the "ASA film speed.")
