Video signal adjusting apparatus, display using the apparatus, and method of adjusting the display |
摘要 |
A color corrector receiving a video signal as an input signal and producing an output signal representing a function of power of the input signal includes a logarithmic converter for achieving a logarithmic conversion of the input signal and outputting a resultant signal, a variable gain amplifier for altering amplitude of the signal from the logarithmic converter and outputting an obtained signal, and an antilogarithmic converter connected to the amplifier for outputting a signal representing an exponential function of the signal from the amplifier.
