Image processing apparatus, image processing method, and image processing system

An image processing method comprising:

• obtaining a rear side camera image captured from a rear side of a vehicle;
• obtaining a virtual viewpoint position that changes in accordance with motion of the viewpoint of the driver, based on a viewpoint position of the driver;
• retrieving, from a memory, 3D computer graphic data of an interior of the vehicle;
• arranging, in a virtual space, the 3D computer graphic data and the rear side camera image;
• and
• converting the arrangement in the virtual space into a projected coordinate system based on the virtual viewpoint position to obtain a display image, wherein the 3D computer graphics of the interior of the vehicle in the display image is changed based on the virtual viewpoint.
