IPC: H04N5/74
Filed: 1990-08-07
Abstract: PURPOSE:To heighten the frequency of flickers synthesized on a screen, and to reduce the apparent flickers only by the addition of a simple hardware by impressing image signals to be impressed on plural LCD pannels after defining one of them as a reference and especially delaying the others. CONSTITUTION:Inputted image signals R and B among inputted one R, G, and B are converted by A/D converters 11R and 11B, and stored in memories M112R and M212B. The memories M112R and M212B delay the A/D converted image signals R and B for a 4/3 frame and a 2/3 frame respectively, and have capacities capable of storing the image signal R for the 4/3 frame and the image signal B for the 2/3 frame, respectively. And also, the outputs of the memories M1 12R and M212B are delayed for the 4/3 frame and the 2/3 frame respectively against the inputs. Thus, the flickers can be reduced without using the hardware of a large size.
