A display control device includes an obtainer and a controller. The obtainer obtains a detection accuracy of an object that exists in surroundings of a movable body. When the obtainer obtains a first detection accuracy, the controller controls an image generator so as to generate a first predetermined image that shows a first graphic having a predetermined shape and divided into n regions (n is an integer greater than or equal to 2). When the obtainer obtains a second detection accuracy that is lower than the first detection accuracy, the controller controls the image generator so as to generate a second predetermined image that shows a second graphic having a predetermined shape and undivided or divided into m regions (m is an integer that is greater than or equal to 1 and that is smaller than n).
