Abstract:
An image display method comprising:generating a synchronization for performing decimation of input vertical synchronizing signals to output decimated vertical synchronizing signals; decimating input image data to output decimated image data; scaling up the decimated image data to output scaled-up image data; displaying an image on a display panel; sequentially displaying individual frames of image according to the scaled-up image data in synchronization with the decimated vertical synchronizing signals; and processing information of a scaling factor of an image scale-up circuit, vertical synchronizing signals to be discarded by an synchronizing signal decimation circuit, and image data to be discarded by an image decimation circuit, a controller controlling operation of said synchronizing signal decimation circuit, an image decimation circuit, an image scale-up circuit, and a driving circuit according to the information.
