Abstract

When an ignition switch is turned on to display an image on a display apparatus, the display apparatus first displays a needle image of meter images and a warning indicator image. Out of the meter images, the display apparatus displays the needle image for a specified time period (e.g., 0.2 seconds), and then displays a dial image. After displaying the dial image for a specified time period, the display apparatus displays a navigation image. The specified time period may be set to 0.5 through 1.0 second, for example, long enough to visually check or recognize display of the meter image and the warning indicator image. Accordingly, it is possible to visually check the meter image and the warning indicator image while the navigation image is not displayed.
