Summary on Grant Application Form
When the same colour image is viewed on different visual display devices (e.g. computer monitors), the image will appear differently on each display due to the monitors' different physical characteristics. This constitutes a problem for many commercial applications where the truthful reproduction of colour is crucial, e.g, for web-based commerce, where the colour of the product is an essential feature. Colour Management Systems use device profiles to map the different physical device characteristics into a common space. The source device profile contains all relevant information about the colour characteristics of the source device (e.g. the vendor's monitor); the destination profile characterises the chromatic properties of the destination monitor (e.g. the end-user's monitor). A colour management system can transform colour information between devices if both device profiles are known. The difficult task is the derivation of the device profile, that is, to obtain the information about the monitor's physical characteristics. Currently, all solutions require the end-user to have some in-depth technical knowledge, a calibration standard or a measurement instrument. We propose a different solution to characterise the monitor output, which is simple and user-friendly: we use the invariant human colour mechanisms as an internal measurement device against which the monitor can be calibrated.
