The colours of objects can be converted into pulses with different frequencies by TCS3200D. Colour recognition system was designed through the combination of Single Chip Microcomputer (SCM) and PC on the basis of the colour vision principle of TCS3200D. Fully utilizing TCS3200D, the system integrates the advantages of photodiodes and converter of light intensity to frequency to simplify circuit. The effects of factors, such as illuminant, orientation and the surfaces of objects, on the measurement were eliminated by the white balance adjustment. Additionally, colour vision errors were effectively reduced by the correction of the measured data with ANFIS and subtractive clustering.
