A device used to scan a traditional X-ray film to create a digital image data file. There are two types of film digitisers in common use. Both use lasers to scan the film to create the digital image; however one uses photo-multiplier tubes (PMT) to capture the light whereas the other uses charged coupled device (CCD) technology. See Charged Coupled Device (CCD) and Photo Multiplier Tube (PMT).

A device used to convert video signals into a digital format suitable for display on a computer screen. Digitisers typically take several seconds to convert an image, and therefore require that the video picture be perfectly still.

an electronic circuit which takes an analogue signal such as a sound of a video signal and turns it into digital information which can be stored and/or manipulated within the computer and output again as a sound or video signal

The Digitiser tool is used for transferring track and terrain information into Rail3D 2kD from scanned maps.

device for converting analogue signals into digital signals

A device which converts analog information into a digital format. The device is commonly used to transform graphical (mapped) information into digital format.

Input device which can be used to trace line data and capture x,y co-ordinates at desired intervals.

A device which converts graphical input into a digital form which can be manipulated in a computer. It consists of a tablet on which a diagram can be mounted, and a pen-like stylus which can be traced around the diagram, producing digital measurements which are fed into the computer.

A computer peripheral device that converts an analogue signal (images or sound) into a digital signal.
