## Abstract

A vehicle-mounted device includes a storage device, an external input unit, a speaker, an image display unit, a touch panel, a control unit, a DVD/CD drive, a GPS, a vehicle speed sensor, and a gyroscope. The touch panel includes a finger rest area to reduce erroneous operation by a finger or hand of an operator due to vibration of the vehicle or other causes, and perform input intended by the operator even under a vehicle-mounted environment. The operator contacts the finger on the rest area thereby stabilizing his/her inputting hand while contacting the touch panel. As a result, erroneous input can be reduced, and input desired by the operator can be easily performed.

## Claims

### Claim 1

An image display device displaying an image for executing the device's own function in a specific area, comprising
an image display unit that displays an image;
a touch panel provided on a front surface of the image display unit to detect position information of a position contacted by an operator; and
a control unit that performs a control process of the image display device based on the position information of the position contacted by the operator,
wherein the control unit is configured to set a predetermined area on the touch panel as a finger rest area; and
wherein when the control unit detects a first position in the finger rest area where the touch panel is contacted, the control unit waits until the touch panel is subsequently contacted, and when the touch panel is a) subsequently contacted in a second area outside of the finger rest area, and b) simultaneously contacted in the first position in the finger rest area and a further position in said second area, the control unit executes a function based on the first position and the further position in said second area where the touch panel was subsequently contacted wherein said function is executed after both the first position in the finger rest area is contacted and simultaneously the further position in the second area is contacted.

### Claim 2 (depends on 1)

The image display device according to claim 1, wherein the finger rest area is set on an entire outer peripheral edge of the touch panel.

### Claim 3 (depends on 1)

The image display device according to claim 1, wherein the finger rest area is set on a bottom side of an outer peripheral edge of the touch panel.

### Claim 4 (depends on 1)

The image display device according to claim 1, wherein a plurality of finger rest areas are set on an outer peripheral edge of the touch panel.
