The following provides a system and method to display images on a display screen (e.g. via a display panel or by projection) and the processing of image data therefor. In one aspect, the system implements a luminance retargeting method for altering the perceived contrast and/or colours of an image to match their appearance under different luminance levels. In another aspect, the system may provide a method for transforming an image locally within a sub-area of an image to adjust image contrast for display by a display device. In yet another aspect, the system may provide a method for transforming an image of a first luminance to adjust a perceived colour hue thereof for display by a display device according to a second luminance. In yet another aspect, the system may provide a method for transforming an image having a first luminance to adjust a colour saturation thereof for display by a display device having a second luminance.

Described herein is a system and method for tinting of a computer-generated object. Selection of a target color to be applied to be an object is received. The target color can have a luminosity component and a chroma component (e.g., the luminosity, hue, chroma (LHC) color space). Based, at least in part, upon at least one of the luminosity component or the chroma component of the target color, one or more tinting methods of a plurality of tinting methods is selected to tint the object to the target color. The object can be tinted using the selected one or more tinting methods, and, the tinted object provided (e.g., stored and/or displayed to a user via a graphical user interface).

A data processing method, a system and a user interface are disclosed, for dosing ink in a digital printer with at least 6 ink channels. A forward transformation model is obtained or computed for defining a relationship between coordinates of device-dependent ink values across the ink channels and coordinates of device-independent colorimetric values in a color space. An inverse model of the forward transformation model is computed, wherein the inverse model comprises an adjustable constraint on each ink channel. One or more constraints are applied to each ink channel with predetermined and/or user-defined value(s). A target colorimetric value is input to the inverse model. An ink value is computed for each ink channel with the inverse model, wherein each computed ink value corresponds to ink dosage in its respective ink channel and the computed ink values collectively correspond substantially to the target colorimetric value.

An image processing apparatus includes a first acquisition unit configured to acquire first data based on a first image that includes a high-luminance region and a second image that includes an overlapping region with the first image and that does not include the high-luminance region, the first data representing flare distribution in the overlapping region in the first image, a second acquisition unit configured to acquire second data representing a position of the high-luminance region in the first image, a generation unit configured to generate third data representing flare distribution in the first image based on the first data and the second data, and a correction unit configured to correct the first image based on the third data.

Luminance data indicating luminance of the print product illuminated by the lighting is calculated and processing for causing a high luminance region to have gradation characteristics is performed.

An image processing device acquires an image to be processed that includes an image of clothing, the image being composed of a hue, saturation and brightness; calculates a difference between the image to be processed and a plurality of shift images obtained by shifting the image to be processed in units of one pixel by at least one pixel or more in a prescribed direction, and generates a plurality of difference images that correspond to the number of shifted pixels; generates a histogram of differential pixel values for each of the hue, saturation and brightness of the difference images; determines the fabric of the clothing on the basis of the features of the histogram.

The image processing apparatus includes a white balance adjustment circuit configured to adjust a color temperature to RAW data of an image obtained by capturing, a generator circuit configured to generate data of planes for each component of the image from data of which color temperature was adjusted, and a RAW encoding circuit configured to conduct compression encoding of the data of the planes.

An image processing apparatus includes a skin area detection unit configured to detect a skin area of an object person, a difference area detection unit configured to detect a difference area between the visible light image and the infrared light image, a correction target area detection unit configured to detect a correction target area of the object person based on the skin area detected by the skin area detection unit and the difference area detected by the difference area detection unit, and a correction unit configured to correct the correction target area in the visible light image.

The invention provides a colour standard, assembled from a graphic digital input file, in which one or a combination of CMYK, RGB, Lab or spot colour builds are contained. The colour standard comprises a colour target calibration strip which is indicative of the calibration status of a printing press; an output image which is indicative of the digital input file; and a grid chart of spot colour builds, built-in process inks, with their respective process build values available for each spot colour in the digital input file. The colour standard is configured to capture the calibrated state of the press for a particular digital input file in order to achieve a particular colour-managed output image, so that product print runs of the output image can be repeated accurately and consistently over time.
