DISPLAY CONTROL DEVICE AND DISPLAY CONTROL METHOD

When a narrow angle image is switched to a wide angle image, a captured image is displayed without causing visual discomfort for a user. A display control device 1 is disposed in a vehicle M1 in which a camera 3 that photographs a first captured image indicating an image on a rear right side of the vehicle M1 and a display 2 that displays the first captured image are mounted. The display control device 1 includes an image acquiring unit 11 that acquires the first captured image from the camera and a display control unit 14 that controls the first captured image displayed on the display 2. The display control unit 14 causes the display 2 to display one of a narrow angle image P11 indicating a part of the first captured image and a wide angle image P12 indicating an image in a range wider than the narrow angle image P11 in the first captured image and causes the display 2 to display the first captured image such that a size of a first region AR1 in displaying the wide angle image is large compared with a size of the first region AR displaying the narrow angle image.
