Patent ID: 7280260

Claim:
A color converting apparatus, comprising: an image data inputting portion inputting image data; a color converting portion performing color conversion on the image data to generate converted image data, the color converting portion performing the color conversion by using information on output-end color conversion characteristics, which is determined based on information on excitation characteristics of a color that is outputted by a color outputting device; and a converted image data outputting portion outputting the converted image data, wherein the color outputting device outputs the color in response to a color control signal i, the color producing light with a generated light wavelength λ 0 in response to incidence of light with an incident light wavelength λ, a set of excitation characteristics data Bi (λ 0 , λ) being defined as indicating a ratio of an amount of the light with the wavelength λ 0 relative to the amount of the light with the wavelength λ, the generated light wavelength λ 0 being equal to or different from the incident light wavelength λ, and wherein information on excitation characteristics of the color corresponding to the color control signal i includes a plurality of sets of excitation characteristics data Bi (λ 0 , λ) for a combination of a plurality of incident light wavelengths λ and a plurality of generated light wavelengths λ 0 .
