Abstract
The focusing information visualization system of the invention extracts an edge having an edge intensity of not less than a first reference value Thand an edge width of not greater than a second reference value Thin a photographic image and displays the extracted edge in a preset color at a position of the edge extraction to be overlapped with the original photographic image on a screen. A focused area defined by the extracted edge is displayed as N divisional areas. In response to a user's operational specification of one divisional area among the N divisional areas, an enlarged photographic image corresponding to the specified divisional area at a desired magnification ratio is displayed on the screen. This arrangement adopts the automatic rough judgment and the user's final visual check to accurately recognize the focusing status of the photographic image.
