ABSTRACT:
A solid-state imaging apparatus and its driving method. Addition of 2 lines for example of signal charges in a horizontal transfer block requires to double the transfer rate in order to execute line transfer of 2 lines of signal charges in a limited horizontal blanking period. In the solid-state imaging apparatus or a camera system having a CCD imaging device capable of operating in two modes of frame read mode and addition read mode, signal charges read from a plurality of sensor blocks are added for 2 pixels for example in a vertical transfer block in the addition read mode and the added signal charges are vertically transferred and a saturation signal charge quantity of the sensor blocks in the addition read mode is set to about ½ of that in the frame read mode. To implement these operations, a substrate bias Vsub2having a corresponding voltage value is generated by a substrate bias generator to be applied to a semiconductor substrate.
