Abstract

There are many white objects around us. For example, there are white papers, white clothes, white ceramics etc. Therefore the whiteness perception of white objects plays an important role in the impression of lighting as well as perceived color of colored objects. Whiteness perception of white objects is influenced by color temperature or chromaticity of the light sources more than the colored objects. Ayama et al. has been investigating the relationship between color temperature or chromaticity of the light sources and the whiteness perception of white objects. In this paper an objective method for quantifying whiteness perception is studied. We attempt to investigate the relationship between chroma derived from some recent color appearance models and whiteness perception. Mainly the relationship between chroma derived from CIECAM97s and whiteness perception is discussed. As a result of the investigation, it was made clear that as the chroma becomes lower the whiteness perception becomes higher and that the whiteness perception is equal if chroma is equal even if the hue varies.
