Paper Abstract

There are lots of experimental results concerned with chromatic contrast detection (based on changes in chromatic distribution over space or time), but compared with luminance contrast detection, there has been no theory to describe chromatic contrast detection and thus no mathematic model for isoluminant contrast sensitivity function. After reviewing of many papers, two reasons may contribute to this: I . Isoluminant contrast sensitivity function has the same description method as the isochromatic contrast sensitivity function which is unfit to express the chromatic changes. 2. The color vision is so complicated that further study is needed. Based on detailed analysis of previous works, this paper utilizes colorimetry fundamental principle to present a new theory for color contrast detection, and indicates that isoluminant contrast sensitivity function can be described by two aspects of chromatic changes——dominant wavelength and colorimetric purity. This theory can well explain that red-green and yellow-blue contrast sensitivity functions have similar characteristics.
