A method for determining a pixel output value of an imager; the imager
having a plurality of pixels, a reset switch associated with each pixel
and a select switch associated with each pixel; due to incident
illumination upon a pixel of the imager after a reset period. The method
captures a first pixel output value when the reset switch is OFF during a
reset period and the select switch is ON during a reset period and
captures a second pixel output value when the select switch is ON near an
end of an integration period. If the second pixel output value is
captured when the select switch is ON near an end of a first integration
period, the first pixel output value may be captured when the reset
switch is OFF during a reset period preceding the first integration
period and the select switch is ON during a reset period preceding the
first integration period. Moreover, if the second pixel output value is
captured when the select switch is ON near an end of a first integration
period, the first pixel output value may be captured when the reset
switch is OFF during a reset period immediately following the first
integration period and the select switch is ON during a reset period
immediately following the first integration period.
