Abstract:
In one embodiment a method includes obtaining a white point correction for display device and obtaining a chromatic correction for the display device. The method may also include generating corrected color coordinates based on the white point and chromatic corrections. The method may ensure that images that appear on a display device in a soft proofing environment will be visually equivalent to images that appear on print media.
Abstract:
Methods, systems, devices and the like for measuring, encoding and displaying of object color for digital imaging, to control the apparent color of an item under different lighting or display conditions. The present invention helps provide accurate color for such items, both on the internet and in other situations, and can, if desired, determine whether a display screen is accurately displaying the color and also correct the image on the screen if it is not accurate. Also, probes suitable for taking accurate measurements of the intrinsic color characteristics, or intrinsic wavelength-dependent response, of an object, and software or databases that provide information for a variety of lighting situations and light sources.
Abstract:
Ambient light information (visual environment information) inputted from an ambient light input unit (101) is fed to a visual environment conversion unit (100a), where the colorimetric value of a monitor (103) is found. The colorimetric value is fed to a profile update unit (100b) and a contrast correction unit (100d), which corrects the contrast in accordance with the colorimetric value. The information on the setting of the monitor (103) fed from a monitor control unit (102) is fed to a monitor setting value conversion unit (100c), where a TRC and a matrix are produced in accordance with the setting information altered by the conversion unit (100c) and fed to the profile update unit (100b), which updates a profile stored in a memory (104a) in accordance with the newly produced profile.
Abstract:
A method and a device are disclosed for luminous printing of an original image using fluorescent ink or other fluorescent display pigments. In some embodiments, the original image is separated into multiple layers, including at least a brightness layer and an inverse brightness (or darkness) layer, by applying extracted brightness data and inverse brightness data, to the original image, respectively. Each of the layers is associated with a set of corresponding printing channels. The sets of printing channels are applied by a printing device to print the original image on a print medium, such as paper, mylar, fabric, and other print surfaces. Multiple visual effects may be realized using the aforementioned process, including fluorescent images that are only visible under UV (Ultra Violet) or black light, images with high-fidelity colors under daylight and dark conditions, and shadow effects such as depth illusion.

Abstract:
A method for compensating for effects of illumination when comparing soft proofs to hard copy proofs viewed under non-standard illumination comprises adjusting a standard illumination display profile until estimates of device independent colors produced by the display based on the adjusted profile match the colors corresponding to the non-standard illumination within a predefined tolerance.
Abstract:
A method and apparatus for producing a color conversion profile for use in a color ink jet printer, a color laser printer, or the like. In one embodiment, a spectral printing model converter is used to sample ink amount data to spectral reflectance Rsmp(λ). Using this spectral reflectance Rsmp(λ), colorimetric values CV1, CV2 under two different viewing conditions are calculated, and an evaluation index EI that includes an index of color difference between the colorimetric values CV1, CV2 is calculated. I another embodiment, an evaluation index EI that includes an index of color difference between sample color represented by sample ink amount data and reference color obtained from a reference color patch is calculated. Sample ink amount data having the best evaluation index EI is then selected as a representative sample. Profiles are created from the plurality of selected representative samples.
Abstract:
In one embodiment the invention comprises a display device including at least one illuminant condition sensor. The illuminant condition sensor can provide feedback to the display device regarding the illuminant conditions surrounding the display. Alternatively, the output of the illuminant condition sensor can provide input to a color management module. Either way, illuminant condition information can be provided so that the display device renders color in a manner that accounts for illuminant conditions.
