1. A display control device comprising:
a photodetection sensor configured to detect light from pixels of display screens with both a first display device and a second display device with a pixel size different from that of the first display device in a display system in which a video signal is displayed on a plurality of display devices adjacent to each other as detection targets; and
a display adjustor configured to determine a degree of enlargement or reduction of video signals displayed on the display devices on the basis of a difference between the pixel size of the first display device and the pixel size of the second display device based on a result of detection from the photodetection sensor,
wherein the display adjustor is configured to search for a detection area of the photodetection sensor on each display screen by moving a detection display image for allowing the photodetection sensor to detect light when the detection display image is displayed in the detection area of the photodetection sensor along an edge of the display screen.
