Disclosed is a camera image compensating apparatus for a vehicle, including a detecting unit which detects a base line and a vehicle body contour line; a coordinate storing unit which stores a first reference image coordinate value and a second reference image coordinate value; a first coordinate calculating unit which calculates a first base line image coordinate value and calculates a first vehicle body contour line image coordinate value; a coordinate comparing unit which compares the first reference image coordinate value and the first base line image coordinate value and compares the second reference image coordinate value and the first vehicle body contour line image coordinate value; and a correcting unit which calculates angle change information of the camera, calculates correction information based on the angle change information, and corrects the camera parameter using the correction information.
