ABSTRACT:
An image display obtains a high quality enlarged or reduced image, by making the output image almost the same level of the inputted image. An inputted image signal is transmitted to a discrete cosine transformer and transformed to frequency band information. The image information transformed to the frequency band is transmitted to a memory controller and stored in a frame buffer. Image information read out from the memory controller is implemented enlargement/reduction interpolation at an enlargement/reduction interpolation section. The image information enlarged or reduced is transmitted to a reverse discrete cosine transformer and restored to image information and then outputted. In this image display, even the image is enlarged or reduced, the part of frequency of the image is kept as it is, the deterioration of the image quality is decreased largely.
