【摘 要】显色指数(CRI)和色质指数(CQS)是适用于人眼的两个显色性度量指标,但不适用于电视摄像机。针对电 视系统的应用,新研发并已发布了新的度量指标:电视照明(光源)一致性指数-TLCI。本文阐述TLCI的原理 和评价及检测方法和程序,列举TLCI测试报告的内涵和应用,分析TLCI和CRI之间的关系,并介绍电视灯具匹 配系数TLMF。

【Abstract】Color Rendering Index(CRI) and Color Quality Scale(CQS) are two color rendering index for human eyes, but not suitable for TV cameras. For the application of TV system, the new research and development has released a new metric: Television Lighting Consistency Index (TLCI). In this paper, the author described the principle, method and procedure of TLCI, analyzed the content and application of TLCI test report, the relationship between CRI and TLCI, and introduced the Television Luminaire Matching Factor (TLMF).
【Key Words】Television Lighting Consistency Index; Response curve of the human eye; CCD Response curve; Color Correction; Television Luminaire Matching Factor
在《Protocol》杂志2010冬春季刊上,笔者已谈论过显色性度量。那些论述着眼于早些年的显色指数(CRI)和新近的色质指数(CQS),以及应用这些指数的赞成和反对意见。尽管这些度量彼此各不相同,但都具有一个重要的共同点:它们是适用于人眼的两个度量指标,而没有说明在其他传感器上,诸如应用于视频,或电视摄像机中的传感器,或在胶片材料上,光源将如何呈现颜色。这一切使得电视照明指导...
