Abstract
An image display device includes an image display unit, a capacitance type touch panel that is disposed on the surface of the image display unit, and a signal processing unit that outputs to a control unit a position signal corresponding to a pressed position on the touch panel or a signal corresponding to the distance between the touch panel and a finger based on the capacitance between the touch panel and the finger. When the approach of the finger to the touch panel is detected, sensitivity is lowered and a menu button is displayed. When the finger moves while pressing the menu button, a menu area and a menu icon are displayed. Accordingly, it is easy to operate the touch panel which is applied to a vehicle-mounted apparatus and it is easy to see a display screen.
