我在QUORA上看到有人问类似的问题(
https://www.quora.com/If-the-sta ... d-be-more-expensive),
有个从事电视行业48年的大哥是这么说的:
Television doesn't work that way. In both cameras and monitors (your TV set) the image is scanned one tiny piece at a time. Each piece is called a pixel, and they are arranged in a series of lines stretching across the screen. The finished product is called a "raster".
There are two ways to do this scanning. The first, dating back to the very first implementations of television, did two passes of scanning to create a complete raster, first scanning the odd numbered lines (counting from the top) and then the even numbered lines. Each pass of the scanner is called a field. Two consecutive odd/even fields constitutes a frame. This is called interlacing or an interlaced scan
我对此的理解是早年的电视节目摄影机拍摄过程跟隔行CRT电视机扫描过程类似,拍摄的时候就是栅格化后奇数行一场偶数行一场进行的。
