Summary: | 碩士 === 國立清華大學 === 電機工程研究所 === 81 === A research on simultaneous color contrast is proceeded.
Simultaneous color contrast is an important visual phenomenon
for human beings. It is a phenomenon of spatially chromatic
adaptation as compared to temporal chromatic adaptation. They
are all with the same responsing tendency of color appearance,
so von Kries adaptation rule for temporal chromatic adaptation
can be applied to simultaneous color contrast too. The color
appearance of simultaneous color contrast will be influenced by
varying the spatial configurations of testing and adapting sti-
mulus. After our experiments and analyses, we conclude that the
stimulated cone number ratio of adapting stimulus to testing
stimulus and the distance between the two stimuli are the two
major global factors on the degree of adaptation. Physiological
evidences are also existed for the two factors. Furthermore, we
formulate a function based on the above two factors to quantize
the degree of adaptation for any spatial configurations of
stimuli. We achieve good simulation results. This thesis
combines the experiments on color perception and analyses in
color appearance model. It provides a good way on quantizing
the color perception of human beings.
