Experimental setup. (A) Normalized spectral power distribution of the emission from the 6-color projector. The spectral power distributions of #1 projector are B1, G1, R1 and those of #2 projector are B2, G2, R2. (B) Presentation sequence of reference and test stimuli in the measurement of perceived brightness. (C) Presentation sequence of test stimuli in the measurement of pupil diameter.
