Abstract
An image processing apparatus includes an image reading unit to read a plurality of different images from a single image at various focal distances, and an image processing unit to extract clear pixels from the read images to synthesize the extracted pixels. According to the apparatus and a method thereof, an image is scanned several times at various focal distances to extract pixels having a clear picture quality in each corresponding pixel or block, and a synthesized image including only the extracted pixels is generated, so that the construction of the image processing apparatus can be simplified and the manufacturing cost thereof can be minimized while a clear image is being obtained.
Claims23
