<p>PURPOSE:To easily confirm the availability of key input by providing a control part which reads image data corresponding to a detected key out of an external storage device and an arithmetic means which generates display image data for enlarging and displaying an image corresponding to the key input information according to the image data. CONSTITUTION:The arithmetic means 13 receives the image data, the image data consisting of enlarge image plane data 23 and corresponding key data 24, and the key input information and compares the corresponding key data 24 with the key input information. When there is no key input or when there is the key input and the key input information and corresponding key data 24 are different from each other, the normal image plane data 22 is sent back to a control part 12 and when the key input information and corresponding key data 24 are equal, the enlarged image data 23 is returned to the control part 12. Consequently, the image data can be generated by enlarging the key image corresponding to the key input and the touch panel input device with high operability is obtained.</p> |
