Patent ID: 8905299

Claim:
Apparatus comprising: at least one scanner, wherein the at least one scanner includes at least three light sources, each operable to respectively emit a different color of light, wherein the at least one scanner includes a plurality of sensors arranged in a row, wherein each sensor is operable to acquire pixel data representative of light intensity, wherein the at least one scanner is operable to acquire an electric image of at least one side of a document as the document moves relative to the row of sensors, wherein the electronic image comprises a plurality of respective parallel scan lines corresponding to respective strips of the at least one side, wherein respective scan lines include a plurality of pixel data representative of levels of intensity of light reflected from the respective strip and sensed by the sensors for two of the colors of light per pixel, wherein the at least one scanner in acquiring the pixel data for a respective scan line, uses the two colors to sequently illuminate the respective strip, resulting in non use of at least one of the colors in illuminating the respective strip, wherein at least one set of three sequentially adjacent scan lines includes: a first scan line comprising pixel data acquired during illumination of a first one and a second one of the at least three light sources, a second scan line comprising pixel data acquired during illumination of the second one and a third one of the at least three light sources, and a third scan line composing pixel data acquired during illumination of the third one and the first one of the at least three light sources; wherein the electronic image allows for generation of a reconstructed electronic image of the at least one side wherein for each respective scan line corresponding to a respective strip, the reconstructed electronic image includes the acquired pixel data and additional pixel data interpolated using at least one adjacent scan line adjacent to the respective scan line, wherein the additional pixel data is representative of a sensed intensity of light reflected from at least one adjacent strip adjacent to the respective strip, for at least one of the colors not used in illuminating the respective strip.
