Jerry Wagner - Boise ID, US

International Classification:

H04N 1/04

US Classification:

358474

Abstract:

In one embodiment, a method for duplex scanning includes: illuminating a first side of an object with light of a first color from a group of colors; sensing the first color light reflected from the first side; illuminating a second side of the object opposite the first side with light of a second color from the group of colors simultaneously with the act of illuminating the first side with the first color light; and sensing the second color light reflected from the second side. In another embodiment, a duplex scanning method includes simultaneously illuminating each side of a document sequentially with each of multiple colors of light but in different color sequences for each side of the document so that the same color light does not illuminate both sides of the document at the same time.

International Classification:

H04N 1/60

Abstract:

A method for color correction of an image includes generating a plurality of gain modules for an image scanning device, where each gain module of the plurality of gain modules includes a ratio of a maximum light intensity and a scanned white intensity. The method may further include generating a plurality of color correction modules, wherein each color correction module is associated with a respective gain module. Responsive to receipt of instructions to perform a scan of a document, the method may include identifying a color correction module of the plurality of color correction modules to apply and applying the identified color correction module to an image of the scanned document.

International Classification:

H04N 1/028

Abstract:

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.
