摘要 |
The output voltage of a pixel is held as a reference signal output voltage in a reference signal holding capacitor connected to a positive input terminal of a second subtractor by lowering the potential of a reset voltage to that of a calibration voltage and by activating a reset pulse and a reference-signal-calibrating pulse. Then, the reference signal output voltage is output from the second subtractor. And a corrected reference signal output voltage, obtained by subtracting the reference signal output voltage from a no signal output voltage, is held in a corrected reference signal holding capacitor. Moreover, a divider divides a corrected original signal output voltage, which is held in a corrected original signal holding capacitor, by the corrected reference signal output voltage, which is held in the corrected reference signal holding capacitor.
