Abstract
An image acquisition and processing system includes an image sensor and one or more processors that are configured to receive at least a portion of at least one image from the image sensor. The dynamic aim of the image sensor is configured as a function of at least one feature extracted from at least a portion of an image. To accomplish the task, the system utilizes a series of adaptive thresholds used in parallel comparators to determine whether or not a pixel in a given image scene falls on the edge of a given lane line on a road. The location of the lane lines are then used to determine the scene vanishing point, which ideally will be co-located at the optical scene center. If they are not in agreement, the pixel data set being processed can be adjusted to accommodate for any disagreement.
