Colour Characterisation of a High-Resolution Digital Camera

摘要

A calibrated monochromatic light source was used to characterise a high-resolution digital camera, by measuring RGB responses of the camera at successive wavelength intervals throughout the visible spectrum. The results were compared with those obtained by the conventional polynomial modelling technique on colour patches measured directly by the camera using a target. Analysis of the results indicated that accuracy of the modelling technique was lower because of flare and non-uniformities resulting from imaging of the whole chart.
