IMAGERS HAVING VARIABLE GAIN AND RELATED STRUCTURES AND METHODS

摘要

The present application relates to imagers having variable gain and related structures and methods. The gain of the imager may vary between rows of the imager. Such variability may be achieved by suitable design of a readout integrated circuit (ROIC). The ROIC may provide different integration period durations for different rows of the imager. Different integration capacitances may be provided for pixels of different rows of the imager. The gain of a column buffer may be varied when operating on output signals of pixels from different rows.
