たビデオ信号に前記同期信号を加算し、出力ビデ
オ信号を形成する映像処理装置において、 前記同期信号の信号幅を所定量だけ幅広に補正
する信号幅補正手段と、 幅広に補正された前記同期信号の振幅を所定量
だけ大きく振幅補正手段と、 前記処理したビデオ信号と前記振幅補正手段を
介した前記同期信号との加算信号を同期信号先端
レベルが規定レベルになるようにスライス補正し
前記出力ビデオ信号を形成する出力補正手段と を備えた映像処理装置。[Claims for Utility Model Registration] In a video processing device that removes a synchronization signal from an input video signal and adds the synchronization signal to a processed video signal to form an output video signal, the signal width of the synchronization signal is increased by a predetermined amount. signal width correction means for increasing the amplitude of the synchronization signal corrected to make it wider by a predetermined amount; and addition of the processed video signal and the synchronization signal via the amplitude correction means. A video processing device comprising: output correction means for performing slice correction on a signal so that a leading edge level of a synchronization signal becomes a specified level to form the output video signal.
