Abstract
In a display control device, in accordance with speed limit information input from an input unit, a control unit senses change in a speed limit of a road where a vehicle travels and after that, in accordance with vehicle information input from the input unit, determines whether or not whether necessity to increase conspicuity of notification of the change in the speed limit. When it is determined that the necessity is high, a display unit is caused to switch display on a display medium from a first presentation image to a second presentation image that indicates a second speed limit by a first switching method. When it is determined that the necessity is not high, the display of the first presentation image is switched to the display of the second presentation image by a second switching method different from the first switching method.
