电视广播是一种极为有力的宣傳教育武器,也是提高人民文化生活的重要工具。因此从开始起,它就受到了广大观众的喜爱,但是,黑白电视只能傳送景物的亮度,不能傳送丰富多彩的色調,这不仅降低了节目的艺术效果,也大大地影响了图象的真实感,使許多原来凭顏色不同来区別的物体失去了差別。在科学、工业和軍事应用中,顏色的傳送往往更为重要,医学中手术用电視設备如果不能傳送顏色,人体內的五脏器官就难于分辨。因此,創造傳送彩色图象的电視系統一直是各国科学研究人員的奋斗目标。可以肯定的說,在不久的将来,电視技术定能解决傳送优質彩色图象和普及彩色电視的課題,使电視从黑白过渡到彩色,电視的前途必然是彩色的。 Television broadcasting is an extremely powerful weapon for propaganda and education as well as an important tool for enhancing people’s cultural life. Therefore, it has been loved by the majority of audiences from the beginning. However, the black and white television can only transmit the brightness of the scenery and can not transmit rich and colorful tones, which not only reduces the artistic effect of the program but also greatly affects the real image Sense, so that many of the original color by different objects to distinguish the difference. In scientific, industrial and military applications, the transmission of colors is often more important. Medical devices that use surgical equipment that can not transmit colors can not distinguish the internal organs of the body. Therefore, creating a television system transmitting color images has always been the goal of scientific researchers in various countries. It is safe to say that in the near future, television technology will certainly solve the problem of transmitting high-quality color images and popularizing color television sets so that the transition of television from black and white to color will inevitably be colored.
