Abstract:
1. An image display apparatus, comprising: a filter which obtains low-frequency image data from input image data; a multiplier which multiplies the low-frequency image data obtained by said filter by a predetermined ratio; a subtracter which subtracts, from the input image data, the low-frequency image data multiplied by the predetermined ratio by said multiplier to obtain high-frequency image data; buffer memories, each of which temporarily stores a corresponding one of the low-frequency image data and the high-frequency image data; a display control unit which reads and displays, in alternate order, the low-frequency image data and the high-frequency image data stored in said buffer memories; and an adjustment unit which adjusts the predetermined ratio so as to set a flicker of an image displayed by said display control unit to a predetermined level.
