DISPLAY CONTROL DEVICE AND STORAGE MEDIUM

The display control device for a vehicle includes: an interface circuit configured to acquire a viewpoint modification operation by a user for a viewpoint operation device and an imaged image from a camera imaging surrounding of the vehicle, a memory storing a vehicle model that is a three-dimensional model of the vehicle, and an arithmetic calculation circuit. The arithmetic calculation circuit determines the modified viewpoint for the vehicle based on the viewpoint modification operation, generates a bird's-eye view image from the determined modified viewpoint based on the imaged image and a vehicle image, the vehicle image being generated based on the vehicle model, and causes a display to display the generated bird's-eye view image. The arithmetic calculation circuit sets a first transparency level for the portion of the imaged image where the vehicle image overlaps to allow the imaged image to be transparent in the vehicle image in one part, sets a second transparency level which is higher than the first transparency level for the portion where the vehicle image overlaps to allow the imaged image to be transparent in the vehicle image in the other part, and changes, according to the modified viewpoint, range of each of the portion in which the first transparency level is applied and the portion in which the second transparency level is applied in two-dimensional position coordinates of the bird's-eye view image.
