Systems for wide-gamut display are being attracted attention, but conventional color cameras cannot capture color signals in the expanded color gamut. This paper presents a method for evaluating the capability of capturing wide color gamut, and the evaluation results of six-band camera systems comparing with a three-band system. The numerical evaluations show that six-band systems realize a wide color gamut with little loss of signal to noise ratio, and with good color accuracy. In addition, a subjective evaluation demonstrates the capability of six-band systems to acquire deep and vivid colors without loss of naturalness.
