Information processing apparatus, information processing method, and computer readable-recording medium

摘要

An information processing apparatus comprises an operating module to which a touch operation performed with a pointing tool is entered; a calculating module that calculates a reference distance that is a distance between a reference point on an image display area of an operation display surface and a point on the image display area defined by a first operation performed on the operating module with a single piece of the pointing tool, calculates a control distance that is a distance between the reference point and a point on the image display area defined by a second operation performed on the operating module with a single piece of the pointing tool, and calculates a magnification ratio based on the reference distance and the control distance; and a magnification/reduction module that generates a scaled image by magnifying or reducing a display image displayed on the image display area by the magnification ratio.
