<p>PURPOSE:To exactly execute a touch input operation even in the case a touch position is small and narrow with a usual display by bringing the vicinity of its touch position to enlarged window display against the touch input, executing the touch input again in its enlarged window display and detecting a touch position. CONSTITUTION:At the time of touching a touch detection area 5 of the display contents 4 displayed on a display screen 2, a touch panel 3 detects it, and applies a touch signal to a touch position detecting circuit 6. In the case a touch position is narrow, the enlarged window display of an adjacent area of the touch position is given to the display screen from a screen enlarging circuit 11. By further executing the touch operation, while looking at this enlarged window display, a touch area enlarging circuit 10 detects the touch position on the enlarged window display, and a touch position collating circuit 12 calculates a regular touch position and outputs it. In such a manner, even in the case the touch detection area is small and it is difficult to touch it exactly by the usual display, the input can be executed by touching easily a correct position.</p> |
