发明名称 GAMMAKORREKTIONSKRETS FOR TELEVISION
摘要 A television gamma correction circuit in which a gamma corrector supplies an output signal having a minimum gamma equal to two, from which, relative to a linear input signal which is limited via a signal limiter circuit to the peak-white value, a correction signal is derived, with positive values only intended for increasing the gamma of the output signal of the gamma corrector. In this way scene details produced when the peak-white value is exceeded are prevented from being displayed with a lower picture brightness than associated with the peak-white value.
