VEHICULAR VISION SYSTEM WITH REDUCED MEMORY FOR ADAPTABLE GRAPHIC OVERLAYS

A vehicular vision system includes a camera disposed at a vehicle, an electronic control unit, and a video display disposed in the vehicle. The system, responsive to processing of captured image data, displays video images on the video display. The system retrieves graphic overlay data from memory. The graphic overlay data represents a plurality of graphic overlay portions, with each graphic overlay portion being associated with a respective display portion of a plurality of display portions of the video display. Responsive to occurrence of a driving condition, the system retrieves graphic overlay data, displays the graphic overlay portions, and adjusts a transparency of one or more of the displayed graphic overlay portions such that at least one displayed graphic overlay portion is viewable by the driver and at least one other displayed graphic overlay portion is not viewable by the driver.
