Abstract:
An imager has an array of pixels arranged in rows and columns, readout circuitry electrically coupled to the columns to receive signals from the pixels, the readout circuitry having at least one signal path with gain switching, and a threshold detector electrically coupled to the readout circuitry to set a gain to be applied by the readout circuitry.
