DISPLAY CONTROL DEVICE, DISPLAY CONTROL METHOD, NON-TRANSITORY COMPUTER-READABLE RECORDING MEDIUM, 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.

1. A display control device in a display system that includes an obtainer that obtains information about a segment length of a road on which a vehicle travels and information about a speed limit of the segment and also includes a displayer which creates a predetermined image according to the obtained information, and which displays the predetermined image on a display medium, the device comprising:
a controller that controls the displayer so that the displayer creates a first predetermined image indicating the speed limit of a first segment and displays the first predetermined image on the display medium, based on the obtained information; and a determiner that, after the information about the speed limit of the first segment has been obtained, determines whether a segment length of a second segment is shorter than a pre-defined length, and determines whether the speed limit of a second segment differs from the speed limit of the first segment based on the obtained information, wherein if the determiner determines that a second-segment length, which is a segment length of a second segment, is not shorter than the pre-defined segment 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 from the first predetermined image to the second predetermined image, in second switching method, which differs from the first switching method, from the first control to the second control.
