ABSTRACT:
A method and apparatus for reducing bloom in an output of a charge coupled device (CCD) image sensor is disclosed. The method includes the step of toggling at least two phases of said CCD after exposure of said CCD. The method and apparatus are particularly useful when a flash of light occurs during the exposure.
