图像内容及文化差异对白场设定的影响

Influence of image content and cultural difference on white point setting

为了研究图像内容对最佳白场设定的影响,根据平均色度坐标不同选取10幅图像,分别沿着或垂直于日光曲线的方向采用软件模拟改变每幅图的白场设置,由测试者选出自己最喜欢的白场设置.为进一步研究地域文化对最佳白场设置的影响,本实验分别在中国、日本和欧洲重复进行.对主观测试结果的统计分析表明:图像内容对最佳白场设置有显著影响,这种影响因地域文化背景不同而不同.中国人喜欢的白场位于日光曲线上方,而日本人和欧洲人则更喜欢日光曲线上偏蓝的白场.这为针对不同地域的市场需求,根据人们喜好来优化显示器白场设置提供了参考.

To study the effect of image content on preferred white point setting,10 images with different averaged color coordinates were selected.For each image,the white point setting was changed along or perpendicular to the daylight curve by simulation,and subjects were asked to select the most preferred white point setting.To further study the effect of cultural difference on preferred white point setting,this experiment was repeated in China,Japan and Europe.From the statistical analysis of the subjective result...
