Display control apparatus, display apparatus, display control method, and program

A display control method comprising:

• acquiring image data from a rear camera configured to shoot a rear view of a vehicle;
• generating display image data in which a pair of predicted course lines and a plurality of assisting lines are superimposed on the image data, the pair of predicted course lines corresponding to a width of the vehicle and being drawn according to a backward movement of the vehicle, the plurality of assisting lines being disposed so that they are arranged side by side in a width direction on both sides of the pair of predicted course lines;
• extracting a marked-off space boundary from the image data, the marked-off space boundary being a boundary in a width direction of a marked-off parking space where the vehicle can be parked;
• determining a positional relation between the extracted marked-off space boundary and the assisting line in the display image data;
• changing a displaying format of an assisting line located on an outer side of the extracted marked-off space boundary from a displaying format of a assisting line located on an inner side of the marked-off space boundary;
• and
• displaying an image based on the display image data in a display unit.
