Image pickup device
Abstract:
In a related-art image pickup device, there is a problem that the power consumption increases. A semiconductor device includes a plurality of pixel circuits connected to one vertical signal line SL, and an inverting amplification circuit configured to amplify a signal level obtained through the vertical signal line SL with an amplification factor determined according to a capacitance ratio between an input capacitor Ci and a feedback capacitor Cf, in which the feedback capacitor Cf is disconnected from an output of the inverting amplification circuit and connected to the vertical signal line SL in a charge recovery period set in a period between a first timing and a second timing, the first timing being a timing when amplification of an image pickup signal read from a first pixel circuit by the inverting amplification circuit has been completed, the second timing being a timing when amplification of a dark level signal read from a second pixel circuit by the inverting amplification circuit is started.
