A system and method for processing color objects provides optimal processing quality by supporting both a perceptual-based color space and a physical-based color space and utilizing both color spaces for color processing in an integrated manner transparent to the end user. The graphics engine of the system includes a module for converting a color object being processed between the perceptual-base color space and the physical-based color space. During color processing that may involve various perceptual-based and physical-based operations, the graphics engine automatically converts the color object from one of the perceptual-based and physical-based color spaces to the other depending on the color processing operation to be performed. The graphics engine may also perform conversions on input graphic data from an input device to one of the dual color spaces for processing and converting a processed class object into the color space of an output device for displaying or printing.

A method and apparatus are disclosed for providing access by applications/utilities/tools to multimedia file metadata originally provided in any of a set of supported formats. A metadata abstraction interface is interposed between multimedia files and applications that seek to read and/or modify metadata associated with the multimedia files. The metadata abstraction interface supports program access to multimedia file metadata provided in a variety of formats and comprises a multimedia application program interface corresponding to a set of core multimedia file metadata management functions accessible by multimedia applications. The metadata abstraction interface includes an extensible set of file type-specific metadata decoders. Each decoder includes a metadata converter for parsing a metadata portion of a multimedia file stored in a particular native format (e. g. ,. bmp). The decoders render metadata in a generic format from the parsed metadata.

The method of the invention adaptively assigns an image data color management action to a component of a computing system. The computing system includes control programs such as an application program and a peripheral driver program. The computing system further includes a peripheral device that may have both software color management capability and hardware color management capability. The method of the invention initially examines received image data to determine at least one characteristic thereof. The method then compares the characteristic with one or more decision parameters that enable an assessment of the complexity of the color management actions required for the image data. Thereafter, based upon the result of the comparing action, the image data is subjected to a color management action by a selected one of the control programs or by the peripheral device, dependent upon the determined complexity of the image data.

A new method and data encapsulation arrangement are disclosed for over-ranging color image data. The resulting data storage format renders color image data sets encoded in the over-ranging format compatible with in-range color image systems. Thus, color images including over-ranging portions will be readable by legacy systems that handle only in-range color data. The new arrangement of the color image data storage comprises a file header segment describing contents of a color image file. The new arrangement also includes an image data segment comprising digital image data representing a set of color image elements encoded in a signed over-ranged color space. A multi-partitioned color image bitmap data segment is created. A first partition in the multi-partitioned bitmap data segment includes image data corresponding to a first color image data word portion associated with an in-range color space. A second partition in the multi-partitioned bitmap data segment includes image data corresponding to a second color image data word portion associated with an over-ranging color space.

A system and method for recoloring color objects selectively applies color processing operations in a particular pipelined sequence to offer improved performance and quality of color processing. The recoloring sequence includes a transformation by a 5Ã5 matrix that handles various types of transformations in the color space of the color object, a gamma correction, a bi-level thresholding operation, and a conversion into a color space, such as the CMYK space, for an output device. Each of these operations in the recoloring sequence may be selectively activated or deactivated depending on the attributes of the color object being processed and the desired recoloring effects. The transformation with the 5Ã5 matrix allows various transformation operations, such as rotation, scaling, translation, shearing, and perspective in the color space of the color object to be combined and performed in a single step, resulting in significantly improved processing efficiency.

A system and method converts input color data in different formats into a working color space. In the case that the input data includes a device color profile and the desired working color space is an RGB space, gamma information of the input data may be extracted from the color profile. In a Simplified extraction process, the gamma information may be extracted by combining one-dimensional LUTs in the profile in a gray-scale conversion to form a gamma table. When the color profile is a more complex profile, such as one of the regular ICC profile format, a full extraction process may be used, in which gamma information is derived from each of the front end, middle and back end portions of the profile. The derived gamma information may then be combined to provide a final gamma table.

A graphics language interpreter includes one or more color converters that accept input color values and that algorithmically convert such input color values to output color values. The color converters are specified by a standard that defines the predefined graphics language. The color converters use color conversion algorithms that are potentially specified by graphics commands during rendering. A lookup component is associated with the color converters. The lookup component indicates output color values corresponding respectively to selected input color values. The lookup component is initialized with output color values that are converted from the selected input color values by the converters. During rendering, the graphics language interpreter uses the lookup component rather than the one or more color converters to convert input color values to output color values.

An extended colorspace which has a higher accuracy and a wider gamut than sRGB color space is disclosed. The extended color space includes an alpha channel which defines the translucency of the color image. The alpha channel is different from known alpha channels in that the inventive alpha channel can represent âsuper transparentâ and âsuper opaqueâ values by allowing the alpha parameter () to be greater than 1 and less than 0. A data structure for storing the extended colorspace information has three fields, a sign field, an integer field and a decimal field. The sign field defines whether an integer is negative or positive. The integer field defines the integer, wherein the integer defines the super or under saturated values for color and alpha components. The decimal field defines the fine detailed information for the value of the color and alpha components.
