<p>PURPOSE:To always detect the correct pushed positions of a touch panel by switching selectively the parameters for calculation of pushed positions in accordance with change in the lapse of time, the environmental change, etc. CONSTITUTION:A CPU 1 scans whether a touch panel 2 is pushed or not every fixed time. If so, the CPU 1 detects the pushed position of the panel 2 by means of a parameter based on the position data inputted through an A/D converter 3. Then the CPU 1 confirms the pushed part of an image shown on a display device 4 and then displays the part through the input processing. The parameter used for detection of the pushed position is changed into a parameter stored in an application program in response to a parameter switching instruction. Thus the correct pushed positions can always by detected on the panel 2 despite change in the lapse of time, the environmental change, etc.</p> |
