A pixel sensing subsystem (110) for a solid state image sensor includes
frame timing logic (114) that produces a frame timing signal indicative
of an end-of-frame time and a beginning-of-frame time and reset logic (116)
that produces a reset signal for a charge accumulator of pixel sensing electronics.
The reset logic (116) asserts the reset signal at least once between the
end-of-frame time and the beginning-of-frame time to prevent saturation of the
pixel sensing element.
