Pixel

An abbreviation of picture element, the smallest element on a monitor screen.

Plug-in Software

A program that extends the functionality of an application program. Plug-in Module CS-U is a driver plug-in that adds scanning capabilities to programs such as CanoScan Toolbox and PhotoStudio 2000.

Preview Area

Area at the right of the Plug-in Module CS-U window used to display preview images. Clicking the [Preview] button causes the scanner to scan its platen and reproduce the image in the preview area. Please note, however, that preview images do not get downloaded to the application program in use.

Preview Scan

A low-resolution, trial scan of an object. The image shown in the preview area can be used to adjust the scan area, brightness and color balance before initiating the final scan.

Remove Dust and Scratches

This function is available with a Film Adapter Unit FAU-S13 equipped CanoScan D2400U. It utilizes the properties of infrared light to detect small flecks of dirt or scratches on film and retouches them.

Resolution

The density of the dots used to express an image. Image fineness or coarseness is expressed as the number of dots per inch (dpi). See also DPI.

RGB

A color set of red, green and blue: the three primary colors of light. The scanner picks up light reflected off objects with its red, green and blue sensors. Color printers output color using the complements to the RGB color set, which are cyan, magenta, yellow and black (CMYK). Cyan, magenta and yellow are called the three secondary colors.
