1. A rear view camera image processing apparatus comprising:
an image signal processor that generates a rear image based on an original rear image collected by a rear view camera;
a first processing unit that corrects a distortion phenomenon of the rear image to generate a distortion correction image, and generates as an output image displayable through a display apparatus;
a second processing unit that reduces a resolution of the rear image generated based on the original real image to generate a reduced rear image and temporarily stores the reduced rear image, and upon receiving an operation control signal, corrects the distortion phenomenon of the temporarily stored reduced rear image, and then recovers the resolution of the temporarily stored reduced rear image, and generates an output rear image; and
an image addition processing unit that delivers the output image generated by the first processing unit to the display apparatus, and confirms an effectiveness of a sync signal of the output image based on a setting signal transmitted from a control device upon an initial operation of the rear view camera, and generates the operation control signal so as for the second processing unit to operate when the output image is not effective,
wherein the first processing unit includes:
a non-safety area dewarp that corrects the distortion phenomenon of the rear image and generates the distortion correction image,
a memory to stores the distortion correction image, and
a display controller receiving the distortion correction image stored in the memory, and converting the received distortion correction image into the output image displayable through the display apparatus.
