A display control device acquires the size of a picture added in advance to picture data and an optimum viewing distance corresponding to the picture. The display control device calculates a viewing distance, in which the relationship between the size of the picture and the optimum viewing distance is equal to the relationship between the display size and the viewing distance, as a recommended viewing distance based on the size of the picture, the optimum viewing distance, and the display size of the picture. Then, the display control device notifies the calculated recommended viewing distance to a user.
