A display control apparatus (120) includes an input unit (121) that receives recognition results of a change in an environment surrounding a vehicle, and a controller (122) that generates and outputs a control signal to an image generating apparatus (130) such that the image generating apparatus (130) generates a first predetermined image representing a first presentation image on a display medium (140). The controller (122) controls the image generating apparatus (130) such that an image sharpness gradually lowers from the first presentation image to a second presentation image lower in image sharpness than the first presentation image on the display medium (140) during a predetermined duration of time, based on the received recognition results.
