1. A method of reducing smear in images captured using an electronic image sensor comprising: generating image signals that represent an electronic image of a scene of interest, some of said image signals including image components and smear components, said image components corresponding to electrical charges collected in said electronic image sensor during an exposure period, said smear components corresponding to electrical charges collected in said electronic image sensor after said exposure period; generating estimated smear signals that represent said smear components of said image signals, said estimated smear signals being based on electrical charges accumulated in said electronic image sensor; and substantially removing said smear components from said image signals using said estimated smear signals to reduce smear in said electronic image.
