ABSTRACT:
An exemplary method for capturing a still image includes: measuring a theoretic exposure time that is suitable for current ambient light conditions; controlling a charge coupled device image sensor to expose itself for a real exposure time according to the determined theoretic exposure time to capture an image signal; and adjusting the captured image signal according to a ratio of the theoretic exposure time to the real exposure time.
