PURPOSE:To output the spectral distribution property of all the colors of a visible area with a simple construction by constituting the device by an excitation purity operating part, a primary color generating part and a synthesizing part to synthesize and to output the spectral distribution of achromatic colors and the spectral distribution of primary colors with proportion corresponding to calculated excitation purity. CONSTITUTION:An achromatic color generating part 13 finds the spectral distribution of achromatic colors to possess brightness same as that of a color outputted from a color output part 11 and output to a synthesizing part 18 and an excitation purity operating part 14 operates the excitation purity of the color with using the chromaticity component of the color outputted from a color output part 11. A primary color generating part 15 finds a primary color of which excitation purity becomes maximum, finds the spectral distribution of time when brightness is made equal to the brightness of the color outputted from the color output part 11 and outputs to a synthesizing part 18. The synthesizing part 18 synthesizes the spectral distribution of the inputted achromatic colors and the spectral distribution of the primary colors at proportion corresponding to the calculated excitation purity and outputs a synthesized result as the spectral distribution of the objective color. Thus, the spectral distribution property of the all the colors of a visible area can be outputted with a simple constitution. |
