Abstract
An image display apparatus has a synchronizing signal decimation circuit for performing decimation of vertical synchronizing signals, an image decimation circuit for performing decimation of image data, an image scale-up circuit for scaling up the decimated image data, a display panel for displaying an image, a driving circuit for causing the display panel to sequentially display individual frames of image according to the scaled-up image data in synchronization with the decimated vertical synchronizing signals, and a controller having information of a scaling factor of the image scale-up circuit, vertical synchronizing signals to be discarded by the synchronizing signal decimation circuit, and image data to be discarded by the image decimation circuit. The controller controls operation of the synchronizing signal decimation circuit, the image decimation circuit, the image scale-up circuit, and the driving circuit according to the information.
