Abstract:
1. A solid-state imaging apparatus comprising: an imaging area wherein a plurality of pixel circuits are arranged two dimensionally, and each of the pixel circuits includes a vertical scanning circuit for controlling the plurality of transfer switches; a horizontal scanning circuit for reading out the voltage amplified by the amplifying transistor; and a power source circuit for controlling a voltage supplied to the amplifying transistor to set the amplifying transistor to an activation state or a non-activation state, wherein the plurality of transfer switches transfer the electric charges from the plurality of photoelectric conversion elements sequentially to the floating diffusion portion while maintaining the amplifying transistor at the activation state, the horizontal scanning circuit sequentially reads out the voltage corresponding to the electric charges of the plurality of photoelectric conversion elements, and a time period of maintaining the amplifying transistor at the activation state includes at least a part of a horizontal scanning period.
