Abstract
Techniques related to automatic aperture control for an imaging device are discussed. Such techniques may include implementing an aperture control value to adjust an aperture opening, measuring a rate of change in measured luminance at an image sensor in response to the aperture control value, and determining an aperture control hold value to hold the aperture opening at a current position using the aperture control value and the rate of change.
