PURPOSE:To decrease the noises generated at the time of correction by a pseudo pattern removing circuit. CONSTITUTION:A pseudo pattern removing circuit 45 for adding correction values consists of a correction quantity control section 42, a phase inversion circuit 46, a correction quantity output section 43 and a correction adder circuit 44. This pseudo pattern removing circuit 45 is inserted into the circuit and a phase inversion signal input terminal 47 for inverting + and - by each frame is connected to this phase inversion circuit 46. The correction quantity added with odd frames is then eventually subtracted by even frames, by which the additive quantities are offset and the display device no longer receives the influence of the noises. The pseudo patterns when input levels are made continuous are decreased. |
