Abstract
A method for dynamically calibrating an image capture device comprises: a) determining a distance (D, D) to an object within a scene; b) determining a first lens actuator setting (DAC) for the determined distance; c) determining a second lens actuator setting (DAC) providing maximum sharpness for the object in a captured image of the scene; and d) storing the determined distance (D, D) and the first and second lens actuator settings. These steps are repeated at a second determined distance separated from the first determined distance. A calibration correction (ERR, ERR) for stored calibrated lens actuator settings (DAC, DAC) is determined as a function of at least: respective differences between the second lens actuator setting (DAC) and the first lens actuator setting (DAC) for each of the first and second determined distances; and the stored calibrated lens actuator settings are adjusted according to the determined calibration corrections.
