1. A method of de-emphasizing fixed vehicle-mounted objects within a rear camera display, comprising:
collecting, with a data processor mounted within a vehicle and in communication with a rear camera system of the vehicle, a plurality of sequential images captured by the rear camera system as the vehicle moves in reverse;
comparing, with the data processor, the plurality of sequential images captured by the rear camera system;
identifying, with the data processor, fixed vehicle-mounted objects within each one of the plurality of sequential images;
calculating, with the data processor, a portion of each one of the plurality of sequential images that is obscured by identified fixed-vehicle objects as a percentage of a total area captured by the rear camera system; and
when the calculated portion of each one of the plurality of sequential images that is obscured by identified fixed-vehicle objects lies within a pre-determined range:
outlining, with the data processor, identified fixed vehicle-mounted objects within the rear camera display;
de-emphasizing, with the data processor, the identified fixed vehicle-mounted objects within the rear camera display;
identifying, with the data processor, objects that are not mounted on the vehicle and are positioned behind the vehicle that are at least partially obscured by the identified fixed vehicle-mounted objects within the rear camera display; and
emphasizing, with the data processor, the identified objects that are not mounted on the vehicle.
