摘要： 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.

摘要： A method for obtaining a reflectance function from a camera output includes the following steps: uniformly sampling the visible range of wavelengths (λ = a t o λ = b) by choosing an integer n and specifying that λ i = a +(i-l)Δλ, i =1,2,...n, with formula (I); defining a relationship between camera output and reflectance function, using the following equation: P = W T r , where P is a known camera response vector, W is a known weight matrix derived from an illuminant function and the spectral sensitivities of the camera sensors, W T is the transposition of the matrix W and r is an unknown n component column vector representing reflectance function defined by formula (II): where R(λ 1 )to R(λ n ) are the unknown reflectances of the observed object at each of the n different wavelengths; and finding a solution for P = W T r which includes a measure of both the smoothness and the colour constancy of the reflectance function, the relative importance of smoothness and of colour constancy being defined by respective weighting factors. The above method results in a reflectance function which is relatively smooth and which preferably has a high degree of colour constancy, and is therefore realistic.

摘要： As apparatus and method for assessing colour fastness involves the use of digital imaging means to capture an image of a test sample and a control sample. Information relating to the images of the test sample and the control sample is processed to obtain colour values for each sample which may then be compared, to provide an indication of fastness based on the difference therebetween. Using the above apparatus and method, fastness may be assessed automaticall in a reliable manner.
