A display device, a mobile device, a system including the same, and an image quality matching method thereof are provided. According to the method, the mobile device acquires a first acquired image that is an image of a first displayed image being displayed on the first display device and a second acquired image that is an image of a second displayed image being displayed on the second display device, compares the first acquired image and the second acquired image with each other, determines an image quality correction value for the first display device so that an image quality of the first displayed image is made substantially equal to an image quality of the second displayed image, and transmits the determined image quality correction value to the first display device or the second display device.

Systems and methods for color calibrating an image are described herein. In some embodiments, a method includes disposing a unique identifier and a fiducial marker that includes a plurality of color regions on an object. A first image of the object is captured with a first camera and a second image of the object that is captured with a second camera is received. The second image is associated with the first image based on the unique identifier and spectral information of at least a portion of the fiducial marker in the second image is compared with spectral information of at least the portion of the fiducial marker in the first image. Based on the comparison, the second image is resampled to substantially match at least the portion of the fiducial marker in the second image to at least the portion of the fiducial marker in the first image.

A color conversion apparatus includes an independent color value converting circuit and a display color value converting circuit. The independent color value converting circuit converts the image color value into an independent color value independent from a device. The display color value converting circuit converts the independent color value converted by the independent color value converting circuit into the display color value. The independent color value converting circuit converts the image color value into the independent color value indicative of the print color by the print device corresponding to the print color value converted from the image color value. The display color value converting circuit converts the independent color value into the display color value based on display-device-property information indicative of a correspondence relationship between the display color value and the independent color value indicative of the display color by the display device corresponding to the display color value.

Example implementations relate to cross-calibration of imagers. For example, cross-calibration of imagers can include modeling a response of each of a plurality of imagers to a color sample, modeling a response of a composite the a plurality of imagers to the color sample based on the modeled response of each of the plurality of imagers to the color sample, generating generate a cross-calibration of the modeled response of each of the plurality of imagers to the modeled response of the composite of the plurality of imagers, and generating a calibration of the modeled response of the composite of the plurality of imagers to a response of a reference imager.

An image processing apparatus includes circuitry that estimates a first geometric transformation parameter for aligning first output image data with the original image data, the first output image data being acquired by reading a first output result, and a second geometric transformation parameter for aligning second output image data with the original image data, the second output image data being acquired by reading a second output result; associates, based on the first and the second geometric transformation parameters, combinations of color components of the first and the second output image data, corresponding to pixels of the original image data, to generate pixel value association data; determines, based on the pixel value association data, a mapping for estimating color drift between the first output image data and the second output image data from the original image data; and subjects the original image data to color conversion based on the mapping.

Embodiments of the present invention define a Soft Proofing System (SPS) that optimizes the usage of standards and common technologies, without relying on proprietary technologies, to enable the use of a pure web browser environment, without the need for any additional software installation to work together with a server-side application to control and verify accuracy of reception and establish mutual communication in the approval process. This may create an opportunity for large scale, CMS driven, publishing systems, to provide an accurate, distributed, optimized and highly productive collaborative environment to accomplish fast, up to the minute delivery of digital assets to be output to multiple mediums (print and digital formats).

A content item to be displayed via a display of an electronic device may be associated with a first set of grey values or a set of color values. The electronic device may generate, maintain, or at least have access to one or more mappings that map the set of color values and/or the first set of grey values to a second set of grey values. Based on the one or more mappings, the electronic device may convert a color value of the set of color values or a first grey value of the first set of grey values to a second grey value of the second set of grey values. The content item may then be displayed utilizing the second grey value.

A method and system for determining parameters of an image processing pipeline of a digital camera is disclosed. The image processing pipeline transforms captured image data on a scene into rendered image data. Rendered image data produced by the image processing pipeline of the camera is obtained from the captured image data on the scene. At least a subset of the captured image data on the scene is determined and a ranking order for pixels of the rendered image data is obtained. A set of constraints from the captured image data and the ranked rendered image data is determined, each constraint of the set being determined in dependence on selected pair combinations of pixel values when taken in said ranking order of the rendered image data and corresponding pair combinations of the captured image data. Parameters of the image processing pipeline are determined that satisfy the sets of constraints.

Provided is an image conversion method that allows for the representation, on a display, the light and shade of a printed image obtained by printing the image on paper. The image conversion method includes a step of acquiring an illumination-light component and a reflectance component from an input image, a step of correcting the illumination-light component in accordance with display luminance information of a print mode in which the input image is to be printed, so that light and shade of the input image displayed on a display come close to light and shade of a printed image obtained by printing the input image in the print mode, and a step of acquiring a combined image by combining the corrected illumination-light component and the reflectance component or the corrected reflectance component.

Disclosed is a method for producing metadata, comprising: acquiring a first image and a second image which have different gamuts; acquiring at least one of white point information and gamut information with respect to the second image; correcting the first image on the basis of the acquired information; and producing metadata on the basis of the correspondence relationship of color information between the corrected first image and the second image.
