1. A pixel circuit array, comprising:

  • a plurality of pixel circuits; and

    a global reset transistor that has a first end connected to a second end of a reset transistor of each of the pixel circuits and is turned on or off in response to a global reset signal;

    wherein each of the pixel circuits comprises;

    a transmission transistor that receives photocharges from a photodiode through a first end of the transmission transistor and transmits the received photocharges through a second end of the transmission transistor in response to a transmission control signal;

    the reset transistor that has a first end connected to the second end of the transmission transistor and is turned on or off in response to a reset control signal;

    a source-follower transistor that receives a signal output from the second end of the reset transistor through a gate of the source-follower transistor and is turned on or off in response to the received signal; and

    a selection transistor that is connected to the source-follower transistor and is turned on or off in response to a selection control signal.
