Abstract:
    The present invention provides a navigation apparatus, a computer program and a screen control method that can reduce the amount of power to be consumed by screen display operations while information is properly displayed on the screen for a user. When the information to be provided to the user is displayed on the screen of a display device, a system control device determines whether the situation allows the driver to look at the screen of the display device, on the basis of vehicle moving conditions such as the vehicle speed, the traveling direction, and the angle of a turn of the steering wheel detected by a GPS receiving device and various sensors, or map data. If the system control device determines that the situation does not allow the driver to look at the screen, a display control device reduces the luminance of the screen of the display device.
