Scanner

摘要

A scanner is disclosed. The scanner captures three exposures for each color scan line. The scanner has a first, second and third light source that each produces a different color of light. The scanner uses the first and second light source for the first exposure. The scanner uses the first and third source for the second exposure. The scanner uses the second and third light source for the third exposure.

主权项

1. A scanner, comprising:
a first light source that produces light of a first color; a second light source that produces light of a second color, different than the first color; a third light source that produces light of a third color, different than the first and second colors; the three light sources positioned to direct light onto a scanning area; a broadband sensor to receive light from the scanning area: and a controller coupled to the three light sources and the broadband sensor to control the capturing of a sequence of exposures; the controller to use the first and second light sources for a first exposure; the controller to use the first and third light sources for a second exposure; the controller to use the second and third light sources for a third exposure where a color scan line comprises data from the first, second and third exposures, wherein the controller converts data from the first, second and third exposures from a first color space into a second color space before saving the data as a color scan line.
