APPARATUS AND METHOD FOR IMPROVING QUALITY OF ENLARGED IMAGE

摘要

PURPOSE: A device for improving the quality of an enlarged image and a method thereof are provided to display a preview image and an enlarged image for a selected area at the same time without the degradation of quality. CONSTITUTION: A first image input unit (105) and a second image input unit (110) outputs a first and a second images taking the same subject on a position at regular intervals. A first image processing unit (135) converts the resolution of the first image into resolution for preview to output it. An image display unit (145) displays the first image from the first image processing unit. When an enlarged image in the first image is selected, a second image processing unit (140) crops an area corresponding to an area selected from the second image. A control unit (165) controls the image display unit to overlap the cropped image with the first image.
