The process of reducing the effect of the inadvertent movement of the camera. This is done by the use of an image stabilization device built into some digital cameras.

The phrase is easy to define because a “device” is an instrument that performs a simple task. “Input” is also easy - it is something put into a system. So in the technology world, an input device is any tool that feeds data into a computer. For example, keyboards, cameras, scanners, joysticks, and mice are input devices, whereas display monitors and printers are output devices. There are many different types of mouse substitutes that are all considered input devices. These include trackballs, light pens, touch screens, pointing sticks, and touch pads. The microphone is also an input device, and when used in conjunction with voice recognition software, a microphone can be quite an effective way of getting information into the computer.

This is a method for producing an image on a computer screen or television. Interlacing displays the picture by creating two fields for every frame. The two fields are comprised of odd number lines of the image and then the even number lines. To the human eye, the display seems to be complete. Interlacing can produce a certain amount of flickering that is not found in progressive scanning, which is the other type of image display. Interlace is used for most standard definition TVs. High definition televisions displays can be either interlaced or progressive. Interlacing is denoted by the “i” in terms like 1080i and 720i.

The mathematical process of adding and/or subtracting pixels to an image to make it larger or smaller. For digital cameras, interpolation is often used to take a small portion of the image and enlarge it to produce a digital zoom. The image is enlarged by examining each pixel and using complex mathematic calculations to determine the location and color of extra pixels that are added to make the image larger than the original.

Several manufacturers have developed players that play both formats, but these are pricey. HD DVD is backed by Toshiba and some major motion picture studios.
