Image Processing Under Flickering Lighting Conditions Using Estimated Illumination Parameters

A camera comprising:

• an image capturing system;
• and
• an image processing circuit coupled to the image capturing system, wherein the image processing circuit is to:
• receive first image data corresponding to a plurality of captured image frames captured by the image capturing system at a first time period under flickering light conditions,
• receive second image data corresponding to a desired still image captured by the image capturing system at a second time period under flickering light conditions, and
• estimate at least one illumination parameter, which is based on the first image data, by calculating relative average light intensities for each of said plurality of captured image frames.

A method for performing image processing under flickering light conditions comprising the acts of:

• receiving first image data corresponding to a plurality of captured image frames captured at a first time period under flickering light conditions;
• receiving second image data corresponding to a desired still image captured at a second time period under flickering light conditions;
• estimating at least one illumination parameter based on the first image data, wherein said estimating includes calculating relative average light intensities for each of the plurality of captured image frames;
• calculating a point spread function of the desired still image based in part on said at least one estimated illumination parameter;
• and
• de-blurring the desired still image based on the point spread function.
