电视摄象机的光谱特性和矩阵电路

TV Camera Spectral Characteristic and Matrix Circuit

本文首先阐明三管摄象机的理想谱曲线的负叶(瓣)是正确重现基色三角形内的色所必要的,而后在理论上证明矩阵电路能使理想曲线的负叶完全实现。因此我们不再停留于基色信号相加和相减而近似得出这些负叶的说法。

This paper at first explains that the negative lobes of ideal camera(three tubes)spectral curves are necessary for exact reproduction of colours lying inside the primary colour trian- gle,and then proves in theory that the negative lobes of ideal curves can be fully realized by matrix circuit.So that we will no longer stay in tbe way of saying addition and subtraction of primary colour signals to approximate the negative lobes.
