METHOD AND SYSTEM FOR IMAGE COLOUR DEFINITION Russian patent published in 2015 - IPC H04N1/60 

FIELD: physics, computation hardware.

SUBSTANCE: invention relates to image capture and processing. First, produced is the colour images capture map with printed specimens of known colour (for example, coordinates of colour XYZ). Then, tested colour image is captured with the help of accessible household hardware, for example, digital camera or mobile phone with camera. Said image includes also said colour images capture map. Then, regressive analysis is performed using the colour specimen RGB on said image and their known colours XYZ to define the characteristics of image capture device responses. In compliance with one version, colour calibration properties are defined with the help of N known colour specimens of calibration. Note here that N is smaller than the total quantity of known colour specimens of calibration over the entire colour space. Image capture device characteristics defined, colour XYZ of unknown colour specimen can be defined by its colour RGB on the image.

EFFECT: colour specimen colour definition of colour specimen image.
