Abstract:
A colour sensor arrangement comprises a colour sensor arranged to generate at least a first channel signal being indicative of a colour of light incident on the colour sensor. A processing unit is connected to the colour sensor and arranged to generate a tuple of colour signals by processing the at least first channel signal. A memory is connected to the processing unit and a control unit is connected to the processing unit and to the memory. Furthermore, the control unit is arranged to receive calibration data relating the tuple of colour signals to a calibrated tuple of colour signals and arranged to store said calibration data (M) by means of the memory. An interface is connected to the processing unit and comprises an interface terminal.
