In the present paper several theories which might be applicable to the problem of lightness constancy were briefly reviewed. First, it was argued whether perceived lightness could be adequately explained by the luminance ratio principle which suggests that the stimulus correlate of perceived lightness of an achromatic surface is to be found in its ratios to the surrounding in luminance. It was discussed that perceived lightness could not be completely explained by luminance ratio at the retinal level. In the second place, the problem of lightness constancy was discussed from the view-point of the relationship between perceived lightness and perceived illumination. Then, it was suggested that perceived lightness is intimately related to perceived illumination, but the causal relations between these perceptual properties which are suggested by the taking-into-account theory could not be found. And, after all, these percept-percept relationship has important implication for perceptual theory of lightness.
