A system for the high-fidelity display of artwork images simulates lighting conditions (such as by, for example, varying the colour temperature, intensity, and/or lighting direction) and, for each lighting condition, compares an image of an artwork against an image of a digital display thereof. The system calculates an image adjustment (such as, for example, brightness/contrast, levels, tonal curves, exposure, vibrance, hue/saturation and/or colour balance) to minimise perceived visual differences between the original artwork and the image of a digital display thereof under the same environmental lighting conditions. As such, when displayed at a display location, the artwork image may be adjusted using the calculated image adjustment according to the actual lighting conditions at the display location.

In an example there is provided a printing method comprising receiving first and second image data for first and second images to be printed on a substrate, determining first print data for the first image on the basis of the first image data and a white layer to be printed between the first image and second image, to achieve a nominal color profile for the first image; determining second print data for the second image on the basis of the first image data, second image data, the white layer and one or more properties of the substrate to achieve a nominal color profile for the second image; communicating the print data for the first and second images to a printing device to print the first and second images and white layer on the substrate.

An image capturing apparatus that can obtain an optimum image in accordance with a region of interest of a user is provided. An image processing apparatus comprises an image synthesis unit configured to synthesize a visible light image and an infrared light image and generate a synthesis image; a region specifying unit configured to specify a region in the synthesis image; and an evaluation unit configured to evaluate the saturation of the synthesis image in a region specified by the region specifying unit. The image synthesis unit changes the synthesis ratio of the visible light image and the infrared light image in the synthesis image in accordance with the saturation that has been evaluated by the evaluation unit.

The present invention provides an image processing device that reproduces the color of an input image more faithfully under different environment illumination without the need to prepare a different signal separation LUT for different environment illumination. An image processing device in one embodiment of the present invention generates data for generating an overlap image by overlapping an image formed by an image forming device and an image projected by an image projection device. The image processing device includes a generation unit configured to, based on input image data, generate first image data for the image forming device and second image data for the image projection device, a first acquisition unit configured to acquire environment illumination information relating to environment illumination in generating the overlap image, and a correction unit configured to correct the second image data based on the environment illumination information.

Disclosed is an image processing apparatus including: a derivation unit configured to derive a target luminance characteristic based on a viewing condition of an image and a print luminance characteristic predicted based a reflection characteristic corresponding to data thereon; a unit configured to generate print image data on an image by converting input image data by using a tone conversion characteristic that is set based on these characteristics, in which the derivation unit derives, in a case where a reproduction range of an illumination intensity in the print luminance characteristic is different, the target luminance characteristic so that a liner area of an output luminance in a case where the reproduction range is relatively large becomes large.

Methods, systems and computer readable media for color management are described. In some implementations, the method can include accessing one or more buildup curves associated with a combination of a substrate, one or more colorants and a colorant dispenser. The method can also include accessing a design file specifying a design and including one or more layer files each specifying a layer color. The method can further include generating, for each layer color, a corresponding colorization recipe based on the one or more buildup curves. The method can also include creating a production job instruction/metadata file having a link to the design instruction/metadata file and including parameters associated with the colorant dispensing job to be carried out using the design instruction/metadata file.

A device for estimating a scene illumination color for a source image is configured to: determine a set of candidate illuminants and for each of the candidate illuminants, determine a respective correction of the source image; for each of the candidate illuminants, apply the respective correction to the source image to form a corresponding set of corrected images; for each corrected image from the set of corrected images, implement a trained data-driven model to estimate a respective probability of achromaticity of the respective corrected image; and based on the estimated probabilities of achromaticity for the set of corrected images, obtain a final estimate of the scene illumination color for the source image. This approach allows for the evaluation of multiple candidate illuminates to determine an estimate of the scene illumination color.
