PURPOSE: An image signal correcting device of a multi screen display panel is provided to find a vertical synchronization signal of an image signal in a frame buffer which stores the image signal for a fixed period of time to output the image signal. CONSTITUTION: An image processing unit(10) partitions an image inputted from the outside as many as the number of display panels. The image processing unit enlarges the partitioned images. The image processing unit applies the enlarged images to each display panel. Each frame buffer(21~29) is located between the image processing unit and the display panel. Each frame buffer finds a vertical synchronization signal about an image signal outputted from the image processing unit. Each frame buffer applies each image signal to each display panel. |
