Abstract
A touch panel (2) displays an image. A position detection unit (3) detects the XY coordinates of each of two touched positions on the touch panel (2). When the position detection unit (3) detects twice XY coordinates of two touched positions, a calculation unit (4) computes variation amounts of each of the X-direction distances and the Y-direction distances between the two touched positions between the detection of the former coordinates and the detection of the latter coordinates. A control execution unit (5) controls a first controlled object according to the variation amount of the X-direction distances that have been computed by the calculation unit (4), and controls a second controlled object according to the variation amount of the Y-direction distances that have been computed by the calculation unit (4).

8. A display device, comprising:
-
a touch panel for displaying images; a position detector that detects each respective XY coordinate of two touched positions detected on the touch panel; a calculator that when the XY coordinates of the two touched positions have been detected twice, computes differentials of X-direction distances and of Y-direction distances of the two touched positions from a former coordinate detection to a latter coordinate detection; and a control executor that controls a first control subject in accordance with the differential of the X-direction distances computed by the calculator, and controls a second control subject in accordance with the differential of the Y-direction distances computed by the calculator - View Dependent Claims (9, 10, 11, 12, 15, 16, 17, 18, 19, 20)
