Abstract
A driver unit of a solid state image sensing apparatus changes the substrate bias voltage from a first bias voltage to a second bias voltage which is lower than the first bias voltage and is for making a height of an overflow barrier higher than a height of the barrier in the readout gate. Moreover, the driver unit lowers the height of the overflow barrier by superimposing a saturation signal control pulse on the second bias voltage after an end of an exposure period and before sweeping out all the signal charge of vertical CCDs.
