Abstract: PURPOSE:To obtain an output with a smooth gamma correction value in a gamma correction circuit for a display device. CONSTITUTION:In the gamma correction circuit employing a ROM 2 as a table and obtaining a gamma correction output based on data read from the ROM 2, data of the ROM 2 are used for high-order bits and an input video signal is given to a synchronizing separator circuit 4, in which the signal is separated into a horizontal synchronizing signal and a vertical synchronizing signal.
