Abstract
Disclosed is an apparatus and method for color-editing capable of simply carrying out color-editing spectral values, such as spectral reflectance, spectral transmittance, spectral radiance and spectral radiant intensity. When color-editing a spectral value of spectral image, the spectral color is transformed into a low-dimensional color space easy for the human to handle in an HLS space transforming section and color-editing and color-correction are carried out in the low-dimensional color space in on HLS color-editing section thereby generating a proper spectral value from a transformed low-dimensional color in a spectral-space inverse-transforming section. Also, a spectral color editing section receives a spectral editing instruction signal and transforms a wavelength width of a spectral color peak to a narrow one, thereby improving saturation.
