Abstract:
Various embodiments of the present technology may comprise a method and apparatus for reducing spatial flicker artifacts in high dynamic range images produced from multiple image captures with differing integration times. The method and apparatus may comprise, in the image captures, measuring pixel intensity selecting pixels with a predetermined intensity thresholds, calculating a ratio based on a channel selection, normalizing the calculated ratio to an ideal ratio, and applying the normalized ratio to corresponding image pixels in a second image capture to produce a flicker-free image.
