Abstract
An image displaying method and apparatus for simultaneously displaying an enlargement target of an entire original image and its enlarged image on a display screen by automatically disposing the enlarged image. The image displaying apparatus includes display for displaying an enlarged image of part of the entire original image including characters, patterns, etc. in a relation superposed on the entire original image, input apparatus for pointing to specify the enlargement target in the entire original image, and automatic disposing apparatus for preferentially specifying and computing the values of the area of the enlargement target region, the area of the enlarged image display region and the enlargement ratio so as to maximize one of these values and disposing the enlarged image on the basis of the result of computation. Further, in order that the enlarged image is easily visible, the enlargement target region and the enlarged image display region are disposed and displayed on the display screen so that a peripheral region adjoining the enlargement target region is displayed between these two regions.
