摘要:
A method for providing a user access to an extended color gamut digital image and for obtaining payment therefor, comprising the steps of representing the extended color gamut digital image with a limited color gamut digital image and one or more associated residual image(s) representing a difference between the extended color gamut digital image and the limited color gamut digital image; storing the limited color gamut digital image and the associated residual images(s) in an electronic memory; providing the user or user's designee access to the limited color gamut digital image in the electronic memory to provide a preview image; obtaining a payment identifier from the user and making payment using such payment identifier to permit the user or user's designee access to the associated residual image(s); and providing the user or user's designee access to the associated residual image(s) in the electronic memory.
摘要:
A method for correcting for exposure in a digital image, including the steps of providing a rendered digital image suitable for display and displaying such digital image; using an adjustable exposure setting to nonlinearly modify the rendered digital image to effect an exposure change and displaying the exposure modified rendered digital image; and iteratively changing the adjustable exposure setting in accordance with the nonlinear function to continuously change the exposure setting and display modified digital images until a desired exposure modified rendered digital image is displayed.

A method for representing a digital image having color values with an extended color gamut in a storage color space having a limited color gamut includes adjusting the color values of the extended color gamut digital image to fit within the limited color gamut to form a limited color gamut digital image; representing the limited color gamut digital image in the storage color space; determining a set of residual images representing a difference between the extended color gamut digital image and the limited color gamut digital image; and associating the set of residual images with the limited color gamut digital image in the storage color space such that the associated residual images and the limited color gamut digital image is adapted to be used to form a reconstructed extended color gamut digital image.
摘要:
A digital image processing system includes one or more opto-electronic image digitization device(s) which digitize still photographic images and produce an extended color gamut digital image corresponding to each still photographic image, and an image processing unit, coupled with said image digitization device(s), which is operative to receive a plurality of extended color gamut digital images from the image digitization device(s). The image processing unit produces at least one limited color gamut digital image from each said extended color gamut digital image by adjusting the color values of the extended color gamut digital image to fit within a limited color gamut; represents each said limited color gamut digital image in a storage color space; determines one or more residual image(s) each representing a difference between one said extended color gamut digital image and its corresponding limited color gamut digital image; and associates each limited color gamut digital image in the storage color space with its residual image(s) such that the associated residual images and the limited color gamut digital images in the storage color space are adapted to be used to reconstruct extended color gamut digital images.
摘要:
A method for characterizing a response function of an output device, the method comprises the steps of producing a test image on the output device with a set of one or more test patches having known code values; obtaining one or more captured images of the test image using a digital camera; determining colorimetric values for each of the test patches in the captured images using a known response function of the digital camera; and determining a response function of the output device which relates the known code values to the determined colorimetric values.
摘要:
A method is disclosed for calibrating a digital printer to provide a substantially aim printer response. A test target is processed through a set of potential calibration functions to form a set of processed test targets and the set of processed test targets is printed using the digital printer. Thereafter, the printer response for each of the potential calibration functions is evaluated by visually examining the printed set of processed test targets. The potential calibration function that best matches a visual criterion is then selected.
摘要:
A multicolor dye-donor element for thermal dye transfer capable of producing improved color gamut comprising a support having thereon a set of sequential repeating dye patches of yellow, magenta and cyan image dyes dispersed in a polymeric binder, the element also having at least one additional dye patch comprising a dye dispersed in a polymeric binder, the dye of each such additional dye patch which, when transferred to a dye image-receiving layer before or after transfer of the original yellow, magenta and cyan image dyes, has a hue measured at its maximum density which is outside the color gamut defined by the hues of the original transferred yellow, magenta and cyan image dyes by more than 5 CIELAB .DELTA.E.sub.c units.
摘要:
A digital camera for capturing an image containing the photographer, comprising: an image sensor; an optical system for forming an image of a scene on the image sensor; a processor for processing the output of the image sensor in order to detect the presence of one or more faces in a field of view of the digital camera; a feedback mechanism for providing feedback to the photographer while the photographer is included within the field of view, responsive to detecting at least one face in the field of view, and a means for initiating capture of a digital image of the scene containing the photographer.

A method for determining a sharpness predictor for an input digital image includes determining one or more image metrics by analyzing the input digital image; and determining the sharpness predictor from the one or more image metrics.
摘要:
A method for representing an extended color gamut digital image on a hard-copy output medium having a limited color gamut comprising the steps of adjusting the color values of the extended color gamut digital image to fit within the limited color gamut of the output medium to form a limited color gamut digital image, producing a limited color gamut output print from the limited color gamut digital image on the hard-copy output medium, determining a residual image representing a difference between the extended color gamut digital image and the limited color gamut digital image, and encoding the residual image on the output print using a digital encoding means such that the residual image and the limited color gamut output print are adapted to be used to form a reconstructed extended color gamut digital image.
