Claim:
1. A display and input device comprising: a display section configured to display thereon a screen image including a touch screen section configured to detect a touch position on the screen image; a control section configured to a storage section configured to store therein the display and input device uses a normal mode for selecting any of the one or more operation element images and a calibration mode for correcting the detection coordinate data, on detecting a touch operation in the non-operable region the predetermined number of times in succession, the control section switches modes from the normal mode to the calibration mode, additionally displays on the display section a target point image for calibrating coordinate detection other than the one or more operation element images in the calibration mode, determines an amount of deviation between a set of touch position coordinates detected after display of the target point image and a set of display coordinates of the target point image, and calibrates the detection coordinate data such that each set of touch position coordinates subsequently detected is corrected in accordance with the amount of deviation.
