摘要： The present invention includes a plurality of color correction tables respectively corresponding to a plurality of groups into which a page-background color is sorted. It is determined which group a page-background color of image data in a block that belongs to a page-background region belongs to. Consequently, color correction processing is performed by using a color correction table corresponding to the group determined. This makes it possible to carry out appropriate color correction processing according to the page-background color of an original document.

摘要： A method of extending the dynamic range and transforming the color appearance of a digital image includes receiving a source digital image from a capture medium wherein the source digital image includes a plurality of pixel values relating to at least three basic colors. The method further includes calculating a color correction transform by using a non-linear contrast function that is independent of the source digital image and which can be used to extend the dynamic range of the source digital image by correcting an under-exposure condition as a function of the capture medium; and a non-linear color adjustment function which can be used to correct color reproduction errors as a function of exposure associated with an under-exposure condition as a function of the capture medium; and using the color correction transform and the source of digital image to produce an extended dynamic range digital image.

摘要： Disclosed are a method (and computer system embodying the method) of outputting original image data that was generated relative to a first color space by an output device that converts image data of a second color space to a visually-perceptible analog thereof. Such a method comprises: receiving from a provider, over a communication channel, original image data that was generated according to a first color space; receiving from the provider, over a communication channel along with the image data, tag data representing parameters of the first color space; the output device automatically converting the original image data into the second color space according to the tag data to produce converted image data; and the output device converting the converted image data into a visually-perceptible analog thereof. Alternatively, the output device can monitor the presence of tag data. If none is received, the output device can presume that the first color space is a default color space, parameters of which are stored in memory. The output device can convert the original image data into the second color space based upon the presumption that the first color space is the default color space.

摘要： The invention relates to a device for digitally detecting a document (12) having several individual images. Said device comprises a main scanning element (30, 32, 34, 36) by which means at least one main scanning section of the document (12) can be scanned during a main scanning operation. The inventive device also comprises a storage element (38) which enables main scanning values obtained during the main scanning operation to be stored. At least one document-specific parameter can be determined from at least one part of the main scanning values, and the stored main scanning values can be modified on the basis of said parameters during an automatic image processing operation. The at least one part of the main scanning values comprises main scanning values of at least two individual images. The invention also relates to a corresponding method.

摘要： A system and method for color correcting electronically captured input images utilizes a correlation between the input images and a set of reference images of different media types to determine the media type of the input images. In an exemplary embodiment, the correlation is performed using a media correlation matrix (202), which includes media characteristic data from the different media types. The media type information of the input images is used to customize the color correction procedure (410) being performed on the input images. The customization of the color correction procedure ensures that the final images are accurate reproduction of the input images with respect to colorimetric or perceptual match.
