Abstract:
1. A solid state image pickup device, comprising: an arrangement of a plurality of pixels, each pixel of which includes a control transistor configured to switch a connection between the signal output line and a power source terminal configured to supply a potential to the signal output line; and a constant current transistor provided on the signal output line, such that the constant current transistor and the amplification transistor form a source follower, wherein the potential supplied by the power source terminal is of a polarity opposite to a polarity of a potential of a control terminal of the amplification transistor when outputting the amplification signal after a resetting of the control electrode of the amplification transistor, and wherein, during a first period in which the control transistor is turned on, the transfer transistor is turned on after the resetting of the control terminal of the amplification transistor.
