摘要:
An image display apparatus, which is used to display a plurality of images on one display image by carrying out a filtering operation, comprises a memory unit, a filter unit, a write control unit, a delay unit, and a switching unit. The write control unit controls the writing of the display data at a region having a specific address length between adjacent display-regions, when storing the display data into the memory unit. The filter unit applies a filtering operation to the display data read out from the memory unit along the display scanning direction, and the delay unit gives a different delay value to the display data output from the filter unit. The switching unit switches the display data having a different delay value output from the delay unit at a boundary line of the adjacent display-regions. Therefore, the length between the adjacent display-regions can be shortened, and an image having a preferable length between the adjacent display-regions without an intervention can be displayed.
