Abstract
A video signal inverting circuit, wherein a pedestal level of an output signal is selectively changed between a posi-mode and a nega-mode. The pedestal level of the output video signal is set equal to the pedestal level of the posi-mode output video signal in the nega-mode in accordance with a nega-mode/posi-mode control signal. In spite of the nega-mode/posi-mode control signal, a level setting circuit for the posi-mode is used during horizontal blanking period in the nega-mode.
