ABSTRACT:
A display section displays a speedometer having a substantially circular shape on an outer circumference of which a speed scale is provided. Then, that point on the outer circumference of the speedometer which indicates a speed at a moment is calculated. Further a speed that is attained at a given time period (e.g. 0.5 second) after the moment if the speed is increased at an acceleration at the moment is calculated. An arc-shaped pointer is displayed, the arc-shaped pointer passing (i) the calculated point of the speed scale, (ii) a middle point between the calculated point of the speed scale and a center of the speedometer, and (iii) the center of the speedometer. With this arrangement, a display device displaying the speedometer allows a driver to easily recognize the speed and an amount of a change therein (i.e. acceleration).
