Abstract

Methods and apparatus for reconstructing digitized images are provided that include an image reconstruction path that receives a digitized image and provides a processed RGB or CMYK image that may be printed or stored in memory. The image reconstruction path is configured to operate in either a multiple scan or single scan environment if the source of the digitized image is a scanner. A plurality of optional functional units in the reconstruction path can be controlled by user or internal controls. These functional units perform preliminary color adjustment, automatic deskew, background and dust removal, descreen, text detection and enhancement, color conversion, scaling, and color manipulation.

Claims

1. A method for reconstructing a digitized image provided by a scanner or an image memory, the method comprising:

providing the digitized image to an image reconstruction path for or producing RGB and CMYK output images, and that is selectively configurable to process images produced by single scan and multiple scan copy systems ; and

providing the output images to any of a printer or an image memory.

2. The method of claim 1, wherein the digitized image comprises an image that is stored in any known format.

3. The method of claim 1, wherein the digitized image comprises any of video, image, and RGB data.

4. Apparatus for reconstructing a digitized image provided by a scanner or an image memory, the apparatus comprising:

means for providing the digitized image to an image reconstruction path for or producing RGB and CMYK output images, and that is selectively configurable to process images produced by single scan and multiple scan copy systems; and

means for providing the output images to any of a printer or an image memory.

5. The apparatus of claim 4, wherein the digitized image comprises an image that is stored in any known format.

6. The apparatus of claim 4, wherein the digitized image comprises any of video, image, and RGB data.
