采色电视信号与采色接收机若平衡于同一个基准白色,就可以获得逼真的采色及比较少的干扰。这个基准白色平衡于6800°K。但为了得到最大亮度,在美国有120000000部接收机则平衡于约9300°K的白色。目前,新型的萤光粉可以在6800°K白色时获得接近于最大的亮度。由于大量的家庭接收机是平衡于9300°K的,这就要求改变信号的白色色温。作者讨论了这种差别的原因和结果,并阐明所采取的步骤。
If the color television signal and the color pick-up receiver are balanced on the same reference white, realistic color pick-up and less interference will be obtained. This benchmark is white at 6800 ° K. But for maximum brightness, there are over 120,000 receivers in the United States that are balanced at about 9300 ° K white. Currently, the new phosphor achieves near-maximum brightness at 6800 ° K white. Since a large number of home receivers are balanced at 9300 ° K, this requires changing the signal’s white color temperature. The authors discuss the causes and consequences of such differences and clarify the steps taken.
