1. A vehicle camera system comprising:

  • a single camera configured to be positioned at a front portion of a vehicle equipped with the vehicle camera system, wherein the single camera, when positioned at the front portion of the equipped vehicle, has an uninterrupted forward field of view of at least 180 degrees so as to capture image data representative of an uninterrupted view of cross traffic when the equipped vehicle is at an intersection;

    a display configured to be positioned in a cabin of the equipped vehicle so as to be viewable by a driver of the equipped vehicle;

    a processor operable to process image data captured by the single camera;

    wherein the processor receives image data captured by the single camera, the image data being representative of an uninterrupted scene viewed by the single camera;

    wherein the processor performs a first image manipulation on a first portion of received image data that corresponds to a first region of the uninterrupted scene to generate first region manipulated image data;

    wherein the processor performs a second image manipulation on a second portion of received image data that corresponds to a second region of the uninterrupted scene to generate second region manipulated image data, the second region being different from the first region;

    wherein the processor performs a third image manipulation on a third portion of received image data that corresponds to a third region of the uninterrupted scene to generate third region manipulated image data, the third region being different from the first region and being different from the second region;

    wherein the second image manipulation is different from the first image manipulation, and wherein the first image manipulation and the second image manipulation comprise dewarping;

    wherein the third image manipulation is different from the first image manipulation, and wherein the third image manipulation comprises dewarping;

    wherein the processor generates manipulated image data that comprises the first region manipulated image data and the second region manipulated image data and the third region manipulated image data;

    wherein, responsive to being provided with the generated manipulated image data, the display displays a manipulated image based at least in part on the manipulated image data, the displayed manipulated image having a first manipulated region at least partially derived from the first region manipulated image data and a second manipulated region at least partially derived from the second region manipulated image data and a third manipulated region at least partially derived from the third region manipulated image data;

    wherein the displayed manipulated image is discontinuous at a first seam between the first manipulated region and the second manipulated region such that objects in the displayed manipulated image do not line up at the first seam;

    wherein the displayed manipulated image is discontinuous at a second seam between the first manipulated region and the third manipulated region such that objects in the displayed manipulated image do not line up at the second seam; and

    wherein a horizontal line spanning at least partially across the field of view of the single camera, when displayed, is displayed with a first line portion in the first manipulated region vertically offset at the first seam from a second line portion in the second manipulated region, and is displayed with the first line portion in the first manipulated region vertically offset at the second seam from a third line portion in the third manipulated region.
