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. In compliance with one version, said image is, then, transmitted to colour remote definition service to define colour specimen colour. 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. Image capture device characteristics defined, colour XYZ of unknown colour specimen can be defined by its colour RGB on the image. Algorithm of division into clusters is used for identification is several colours of unknown colour specimen exist.

EFFECT: colour specimen colour definition of colour specimen image.
