摘要:
A system and method for image acquisition enables selective automated application of color management to color image data generated by an image-capturing device by the device driver for the device. In the image acquisition system, each image-capturing device has properties or operation parameters that can be set to control the operation of the device. During an image acquisition operation, color image data generated by the image-capturing device are transmitted to the device driver. If the operation parameters of the device are set to indicate that color management is to be performed, the device driver calls color management functions provided by the operating system to perform the desired color operation, such as a color space conversion, on the received color image data. The processed color image data are then sent to the image-processing application for further processing or editing.

摘要:
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. The second partition may optionally include additional precision bits that are concatenated with the lowest precision in-range color channel data of the first partition.
摘要:
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 5×5 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 5×5 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 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.
摘要:
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.
摘要:
In accordance with certain aspects of the removal of redundant information from electronic documents, a package for an electronic document includes a plurality of parts. The package is accessed, and redundant information in one or more of the plurality of parts is identified. The identified redundant information is removed from the package.
摘要:
A document with one or more analog markups is obtained. An original electronic document corresponding to the document is also identified. The one or more analog markups are converted to one or more digital annotations, and the one or more digital annotations are stored in one or more parts of a package of the original electronic document.
摘要:
A plurality of parts for an electronic document are generated. The plurality of parts include a root relationship part that identifies one or more of the plurality of parts, a payload part that stores data for the electronic document, and a tracking information part that stores tracking information for the electronic document. All of these parts are stored in a single package.
