摘要:

介绍了将快速光谱仪和模拟相结合的方法来评价平板显示器彩色运动伪像.采用快速光谱仪SPR-3000来获取交替图案的阶变响应函数表现不同颜色的响应情况;对已获得的阶变响应函数进行傅里叶变换,加权人眼对比敏感度曲线,然后对该曲线进行反傅里叶变换得到符合人眼实际感知的曲线.介绍了延长模糊宽度、人眼感知模糊宽度两种评价方法,并使用人眼感知模糊宽度定量的分析彩色运动伪像.实验中对具有不同波长的单色图案进行测试,证明了不同颜色之间在同样运动条件下所获得的是不同程度的运动伪像.

Abstract:

A method of measuring and evaluating color motion artifacts which combined a flash spectroradiometer with simulation method was presented. Alternative patterns step response curves which show the difference between different colors were obtained with flash spectrum SPR-3000. Perceived response curve was obtained after doing Fourier transformation, weighting contrast sensitivity function and counter-Fourier transformation. Extended blur edge width (EBEW) and perceived blur edge width (PBEW) were introduced here. And PBEW was used to evaluate color motion artifacts. In the experiment, monochromatic patterns with different wavelengths were tested. And the result  proved that under the same moving conditions, motion artifacts will chang in different degrees while the testing colors are changing.
