Patent ID: 8885934

Claim:
A method, comprising: receiving first image data relating to an unknown colour sample, colorimetry data for which is to be determined; receiving second image data relating to a plurality of known calibration colour samples, colorimetry data for which are already known; determining a plurality of colour calibration characteristics relating colour measurements of the known calibration colour samples from the second image data to the corresponding known colorimetry data of the calibration colour samples; calculating colorimetry data of the unknown colour sample in dependence on colour measurements thereof from the first image data and the determined colour calibration characteristics; and matching the determined colorimetry data of the unknown colour sample to a colour palette of paint colours to identify a matching paint colour, and providing information relating to the matching paint colour to a user; wherein the method is performed by an apparatus comprising at least one processor, and at least one memory including a computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform the method.
