1. A method of suppressing flicker in digital images, comprising: deriving pixel values from a non-content area of a digital image; estimating flicker values within said non-content area; and suppressing flicker throughout said digital image based on said estimated flicker values of said non-content area wherein: estimating said flicker values within said non-content area includes analyzing each color channel of said pixel values individually, estimating said flicker values within said non-content area includes determining average pixel value curves that map said pixel values averaged along a direction perpendicular to said flicker within said non-content area for each of said color channels, estimating said flicker values within said non-content area includes identifying local maximums and local minimums of said average pixel value curve, estimating said flicker values within said non-content area includes interpolating an undistorted pixel values curve formed with connecting midpoints between said local maximums and local minimums.
