Abstract
A display control device includes a controller that, if an obtainer obtains first-segment speed limit information, controls a displayer so that it creates a first predetermined image, indicating a first-segment speed limit, and displays the first predetermined image on a display medium, and includes a determiner that, if second-segment length information is obtained after the first-segment speed limit information has been obtained, determines whether the second-segment length is shorter than a threshold. The controller makes a switchover from control under which the displayer creates the first predetermined image and displays it on the display medium to control under which the displayer creates a second predetermined image, indicating a second-segment speed limit, and displays the second predetermined image on the display medium in different control ways depending on whether the second-segment length is shorter than the threshold.

12. A display control device in a display system that includes a detector that detects positional information about a vehicle and includes a displayer which creates a predetermined image according to information about a segment length of a segment of a road and information about a speed limit of the segment and which displays the predetermined image on a display medium, the device comprising:
-
a controller that, if the detector detects that the vehicle is present on a first segment and information about a speed limit of the first segment is obtained, controls the displayer so that the displayer creates a first predetermined image, indicating the speed limit of the first segment when the first predetermined image is displayed on the display medium, and displays the first predetermined image on the display medium; and a determiner that, if the detector detects a travel of the vehicle from the first segment to a second segment and information about a second-segment length, which is a segment length of the second segment, and information about a speed limit of the second segment are obtained, determines whether the second-segment length is shorter than a pre-defined length, and determines whether the speed limit of the second segment differs from the speed limit of the first segment, wherein if the determiner determines that the second-segment length is not shorter than the pre-defined length and that the speed limit of the second segment differs from the speed limit of the first segment, the controller makes a switchover, in first switching method, from a first control under which the displayer is caused to create the first predetermined image and display the first predetermined image on the display medium to a second control under which the displayer is caused to create a second predetermined image, and display the second predetermined image on the display medium, and if the determiner determines that the second-segment length is shorter than the pre-defined length, the controller makes a switchover, in second switching method, which differs from the first switching method, from the first control to the second control. - View Dependent Claims (13, 14)
