Spectral Characterisation of a Digital Still Camera Through a Single Integrating Exposure
This paper describes the basic constructional elements, subsequent calibration and practical use of the device incorporating a trans-illuminated filter array.
The device consists of an array of 36 narrow band dichroic filters in 10nm intervals from 380nm to 730nm, each being illuminated by an individual light emitting diode and the output attenuated by a potentiometer.
The performance of the prototype filter array was evaluated against a polynomial regression technique using a 24 patch GretagMacbeth ColorChecker and was found to produce comparable results.

Started in 2002 and merged with the Color and Imaging Conference (CIC) in 2014, CGIV covered a wide range of topics related to colour and visual information, including color science, computational color, color in computer graphics, color reproduction, volor vision/psychophysics, color image quality, color image processing, and multispectral color science. Drawing papers from researchers, scientists, and engineers worldwide, DGIV offered attendees a unique experience to share with colleagues in industry and academic, and on national and international standards committees. Held every year in Europe, DGIV papers were more academic in their focus and had high student participation rates.
