过去几年里,彩色电视摄象机在控制系统和工作模式方面都发生了很大的变化,图象质量和性能也有了重大改进。所有的彩色电视摄象机都一直在朝着同一个方向(可靠性高,稳定性好和节省劳力)发展。在把计算机技术引入彩色电视摄象机控制系统而将其转换成为数字系统的同时,用于演播室或电子新闻采访的广播彩色摄象机也开始向建立全自动化调整系统的方向发展了。本文讨论用计算机控制的东芝公司PK-40系列演播室彩色摄象机和PK-60电子新闻采访/电子现场节目制作彩色电视摄象机。
Over the past few years, color TV cameras have undergone major changes in control systems and modes of operation, with significant improvements in image quality and performance. All color TV cameras have been moving in the same direction (high reliability, good stability and labor saving). While introducing computer technology into the color TV camera control system and converting it into a digital system, broadcast color video cameras for studio or electronic news coverage have also started to move towards the establishment of a fully automated adjustment system. This article discusses the use of a computer controlled Toshiba PK-40 series studio color video camera and PK-60 electronic news interviews / electronic live show production color TV camera.
