Abstract

An apparatus and method for measuring colours of an object includes: an enclosure for receiving the object; illumination means for illuminating the object within the enclosure; a digital camera for capturing an image of the object; a computer connected to the digital camera, for processing information relating to the image of the object; and display means for displaying information relating to the image of the object. The enclosure may include means for mounting an object therein such that its position may be altered. These means may include a tiltable table for receiving the object, the tiltable table being controllable by the computer. The illumination means are preferably located within the enclosure, and may include diffusing means for providing a diffuse light throughout the enclosure. The illumination means may include a plurality of different light sources for providing respectively different illuminations for the object, one or more of the light sources may be adjustable to adjust the level of the illumination or the direction of the illumination. The light sources may be controllable by the computer.
