1. A method for generating a first document from a second document that is colored, the method comprising the steps of:
- identifying a plurality of colored objects in the second document;
generating a vector for each of said plurality of colored objects, wherein each vector comprises;
coordinates of a bounding box in the document image space that at least approximates shape of an object, andan object type indicator;
encoding the color content and the vectors of the plurality of colored objects to produce encoded color content information;
creating the first document having objects of the second document in monochrome and having the encoded color content information for each object printed in monochrome on the first document.

Abstract
A method and apparatus for encoding color information in monochrome (black and white) documents. The present invention includes a method and apparatus to produce color documents that interprets color information stored on a document containing an image in monochrome and generates an image in color based on the color information.

1. A method for generating a first document from a second document that is colored, the method comprising the steps of:
-
identifying a plurality of colored objects in the second document; generating a vector for each of said plurality of colored objects, wherein each vector comprises; coordinates of a bounding box in the document image space that at least approximates shape of an object, and an object type indicator; encoding the color content and the vectors of the plurality of colored objects to produce encoded color content information; creating the first document having objects of the second document in monochrome and having the encoded color content information for each object printed in monochrome on the first document. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9)

10. A method for generating a black and white document reproducible in color, said method comprising the steps of:
-
identifying one or more objects that contain color in the color document; generating a vector for each of said one or more objects, wherein each vector comprises coordinates of a bounding box in the document image space that at least approximates shape of an object, and an object type indicator; generating encoded color information containing location and color of said one or more objects in the color document, wherein the step of generating the encoded color comprises encoding, as part of the encoded color information, the vectors for said one of more objects; printing the black and white document with the encoded color information to enable creation of a color version of the color document. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A method for generating a black and white document reproducible in color, said method comprising the steps of:
-
identifying at least one bounding box to approximate each of one or more shapes containing color in the document; generating a vector for each of said one or more shapes, wherein each vector comprises coordinates of a bounding box in the document image space that at least approximates a shape, and a shape type indicator; generating encoded color information containing location, bounding box and assigned color of said one or more shapes, wherein the step of generating encoded color information comprises encoding, as part of the encoded color information, the vectors for said one or more shapes; printing the black and white document with the encoded color information to enable creation of a color version of the color document. - View Dependent Claims (22)

23. An apparatus for generating a black and white document reproducible in color, said apparatus comprising:
-
means for identifying one or more objects that contain color in the color document; means for generating a vector for each of said one or more objects, wherein each vector comprises; coordinates of a bounding box in the document image space that at least approximates shape of an object, and object type indicator; means for generating encoded color information containing location and color of said one or more objects in the color document, said means for generating encoded color information comprising means for encoding, as part of the encoded color information, the vectors for said one of more objects; means for printing the black and white document with the encoded color information to enable creation of a color version of the color document. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30)
