Abstract: In a color correction method, a reference area is selected in a document page, which is rendered to produce image data. The reference area can be a company logo, a letter or character in a line of text, or other graphic object. The reference area need not be a set calibration chart. The image data is used by a projector to display the document page on a screen. Ambient light may cause colors in the displayed document page to be noticeably different from the intended colors specified in the document page. A camera takes a picture of the displayed document page, and a target area is identified in the camera image based on a characteristic of the reference area that was previously selected. Corrected image data is generated based on a color difference between the reference area and the target area. The projector uses the corrected image data to display the document page, this time with colors that are closer to or the same as the intended colors.

Abstract: Systems and methods consistent with embodiments presented pertain to the stochastic regression testing of software PDL processors. Test input for PDL processors, which include language processors and raster image processors, may be generated by randomly altering the values of one or more of text, graphical object parameters, image object parameters, graphical combination parameters in an existing PDL input file. In another embodiment, test input for PDL processors may be generated by randomly selecting a first token from a lexical token dictionary and combining the first token with at least one of a plurality of second tokens randomly selected from the lexical token dictionary, so that the combination of the first token and the plurality of second lexical tokens satisfies the syntactical rules for the PDL. In a further embodiment, existing tests in a test pool may split and recombined in a syntactically correct manner to generate new tests.

Abstract: Systems and methods are provided for identifying candidates for trapping in a frame buffer by correlating display list object information stored in an object-ID plane with pixel data in the frame buffer. In some embodiments, the display list of objects may be generated from the PDL description of a document. In some embodiments, object boundaries may be computed by assigning unique identifiers to objects in the object-ID plane and using morphological techniques to identify object boundaries. Object boundary information may then be utilized to perform trapping on pixels in the frame buffer. The methods described may be performed on a computer and/or a printing device and implemented using one or more of combination of hardware, software, and/or firmware.
