Abstract
A vehicular vision system includes an image sensor operable to capture image data and an image processor operable to process frames of captured image data. The image processor is operable to detect edges or corners in the captured images. The image processor is operable to determine a number of edges detected in individual frames of captured image data. The vision system adjusts a sensitivity of the image processor responsive to the determined number of edges detected in at least one frame of captured image data. The image processor may detect up to a selected maximum number of edges in a frame of captured image data, and the vision system may adjust the sensitivity of the image processor so that the determined number of edges detected in a subsequent frame of captured image data is at or near the selected maximum number of edges.
