DISPLAY CONTROL DEVICE, DISPLAY CONTROL METHOD, DISPLAY CONTROL PROGRAM, AND PROJECTING DEVICE

摘要

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.
