System and Method for Color Management of Mixed Content Documents

摘要

A system and method is provided for color managing different content objects in at least one source file. In one embodiment of the present invention, the system includes a color management module, a rendering module, an interface (e.g., GUI), and a memory module for storing a plurality of color profiles. The interface allows a user to specify different color profiles and/or parameters for different object types. For example, the user can specify different source color spaces to use for the default source color spaces based upon object type. Similarly, the user can specify different output color spaces to use based upon object type. Finally, software can be used to generate a map that specifies the object type(s) that leads to the creation of each individual pixel in the rasterized output. Parameters (e.g., brightness, contrast, etc.) of individual pixels can then be adjusted based on object type and user-defined, object-based settings.

1. An apparatus for color management of different content objects, comprising:
at least one memory device for storing at least one source file; an interface allowing a user of said apparatus to adjust a plurality of parameters for a plurality of types of a plurality of objects, said plurality of parameters being stored in said at least one memory device; a color management module configured to convert source data in said at least one source file from at least one source color space into at least one destination color space, said converted source data being stored in at least one destination file on said at least one memory device; and a rendering module in communication with said at least one memory device, the rendering module being configured to:
receive said at least one destination file from said at least one memory device, said at least one destination file having content comprising said plurality of objects;generate at least one raster bit map image from said at least one destination file;identify said plurality of objects in said at least one raster bit map image;generate a pixel/object map by assigning a value to individual pixels within said at least one raster bit map image, wherein a first value indicates the presence of a first one of said plurality of types of said plurality of objects, a second value indicates the presence of a second one of said plurality of types of said plurality of objects, and a third value indicates the presence of both said first and second ones of said plurality of types of said plurality of objects, said third value being mathematically derived from at least said first and second values;adjust said individual pixels within said at least one raster bit map image having said first value in accordance with said plurality of parameters for said first one of said plurality of types of said plurality of objects, adjust said individual pixels within said at least one raster bit map image having said second value in accordance with said plurality of parameters for said second one of said plurality of types of said plurality of objects, and adjust said individual pixels within said at least one raster bit map image having said third value in accordance with said plurality of parameters for both said first and second ones of said plurality of types of said plurality of objects; andprovide said adjusted raster bit map to a destination.
