ABSTRACT:
A solid-state imaging apparatus comprises a semiconductor substrate, a multiplicity of photo electric conversion elements, a vertical electric charge transfer device having a plurality of vertical electric charge transfer channels and transfer electrodes, reading out parts and a driving device that imposes a first voltage to the reading out electrode for reading out the accumulated signal electric charge from the photo electric conversion elements to the transfer channels in a reading out period and at a same time during the reading out period imposes a second voltage to at least one of the transfer electrodes adjoining to the reading out electrode for each photo electric conversion element for accumulating the signal electric charge in the vertical electric charge transfer channel under the one of the transfer electrode. Damage in the dynamic range of the solid-state imaging apparatus can be prevented.
