发明名称 Method and apparatus for the gamma correction of video signals
摘要 A process for the gamma correction of video signals, in which the luminance signal in the signal transmission path and at least one signal containing an item of color information are multiplicatively corrected, provides that, in addition to the luminance signal, at least two color difference signals are corrected by way of individual, controlled correcting stages whose control signals are obtained from the luminance signal. The gamma correction is carried out in a single tube color television camera and provides that an additional color difference signal may be corrected in a separate correcting stage.
