COLOUR CALIBRATION METHOD FOR AN IMAGE CAPTURE DEVICE |
摘要 |
A method for providing a mapping from apparent colour to actual colour for an image capture device including capturing an image of a reference colour chart having a plurality of colour patches using the image capture device, wherein each colour patch has an associated reference colour, measuring the apparent colour of the plurality of colour patches in the captured image, selecting a plurality of control points representing different hue values within a circular hue space, determining an angular offset for each control point such that the distance between a transformed apparent colour and the reference colour for each colour patch is minimised, the angular offset representing a hue correction, wherein interpolation of the angular offsets for the control points provides a mapping from apparent colour to actual colour for the image capture device. |
