Abstract
A camera system is automatically focused based on pixel disparity values calculated by the camera at various times. A lens of a camera is positioned at an initial distance from an imaging sensor of the camera based on an initial digital-to-analog conversion value. Subsequently, pixel disparity values are calculated for each of a plurality of regions of a field of view of the camera. An optimal distance between the lens and the image sensor is calculated based on the pixel disparity values and a fitting constant for the camera, as well as the initial digital-to-analog conversion value, and the lens is repositioned to a distance corresponding to the median. The process may be performed following triggering events, or on a regular basis, and repeated over time.
