1. A display control device, comprising:
an input that receives a first image that captures a front scene, one of in front of a vehicle or in front of a user on board the vehicle, at a first point of time;
a sensor that receives a plurality of images from the input, detects an object included in the first image by subjecting the first image to an image recognition process, and sets an object placement area that encircles the object thus detected in the first image;
a processor that:
generates a third image showing a result of prediction of the front scene at the first point of time, based on a second image that captures the front scene at a second point of time preceding the first point of time; and
compares the first image and the third image by using a predetermined criterion; and
a display controller that controls information presentation based on a result of comparison between the first image and the third image using the predetermined criterion, wherein
the predetermined criterion is whether there is a difference area; in which a difference between the first image and the third image is larger than a first threshold value; and which includes the object placement area,
the processor identifies the difference area in which the difference between the first image and the third image is larger than the first threshold value, compares position information on the difference area with position information on the object placement area of the object included in the first image, and identifies an overlapping area in which the difference area and the object placement area overlap, and
the information presentation is an image that alerts of the overlapping area or the object.
