Abstract
In a correction operating part three regions including two distant regions and one near region are selected on a reference image picked up by a main camera and distance data are added to the positions of the respective regions to define a range, in which corresponding regions exist, in a comparative image picked up by a sub-camera to search the range to determine the positions of the regions at a resolution of one pixel or less. Then, on the basis of one of the distant regions, a translation correction value and an angle of rotation for the comparative image are derived from the relationship between the positions of the respective regions to be added to the set value of an affine transforming circuit to parallel-displace and rotate the comparative image. Thereafter, an angle of rotation for causing the horizontal line of the main camera to be parallel to the base line of a stereo camera is derived to be added to the set value of an affine transforming circuit to rotate the reference image. Thus, the deviation of the optical axis of the stereo camera is automatically adjusted while carrying out a usual operation for picking up an image of an ordinary landscape to carry out the stereo image processing.
