Abstract

A display control device that facilitates an operation on a touch panel, for the timeline display of a moving image. A synthesis section controls display on a touch panel. A touch state-detecting section detects any touched position on the touch panel, and determines whether two touched positions are detected on a single display object displayed on the touch panel. Determining that two touched positions are detected on the single display object, the touch state-detecting section determines whether the detected touched positions are moved while keeping their touched states. When the touched positions are determined to be moved while keeping their touched states, an overall controller extracts frame images of which the number depends on a distance between the two touched positions after the movement thereof, and controls the synthesis section to display the extracted frame images between the two moved touched positions.
