METHOD AND SYSTEM FOR PERFORMING IMAGE PROCESSING ON A DOCUMENT BASED ON A DELAYED DETERMINATION OF WHETHER THE DOCUMENT IS MONOCHROME OR COLOR

摘要

Embodiments include systems and methods for performing image processing on a document based on a delayed determination of whether the document is monochrome or color. The image reproduction system includes image processing hardware configured to receive a plurality of pixels corresponding to a scan document, perform color processing on the plurality of pixels to produce color-processed scan data, perform monochrome processing on the plurality of pixels to produce monochrome-processed scan data, produce color distribution data for the plurality of pixels, and determine from the color distribution data that the scan document is one of a color document or a monochrome document. Based at least on determining that the scan document is one of a color document or a monochrome document, one of the color-processed scan data or the monochrome-processed scan data are discarded.

1. An image reproduction system comprising:
image processing hardware, wherein the image processing hardware is configured to
receive a plurality of pixels corresponding to a scan document,perform color processing on the plurality of pixels to produce color-processed scan data,perform monochrome processing on the plurality of pixels to produce monochrome-processed scan data,produce color distribution data for the plurality of pixels,determine from the color distribution data that the scan document is one of (i) a color document or (ii) a monochrome document, andbased at least on determining that the scan document is one of a color document or a monochrome document, discard one of (i) the color-processed scan data or (ii) the monochrome-processed scan data.
