Abstract
A digital image processing device is provided that improves operability when performing a scaling up/scaling down operation. Based on a single trajectory when a touch position on a display screen of a display portion moves, a center point and ratio used to scale up or scale down the image are set. In this way, for example, it is possible to scale up and scale down the image by an easy touch operation of simply tracing the trajectory with a single finger (namely, by a single-touch operation).
