Abstract

Adelson's tile, snake, and some other lightness illusions of the same type were measured with the Munsell neutral scale for twenty observers. It was shown that theories based on low-level luminance contrast processing could hardly explain these illusions. Neither can those based on luminance X-junctions. On the other hand, Helmholtz's idea, that simultaneous lightness contrast originates from an error in judgement of apparent illumination, has been elaborated so as to account for the tile and snake illusions as well as other demonstrations presented in this report.
