Solid state imaging apparatus and a driving method of the solid state imaging apparatus

摘要

A first voltage is impressed to a reading out electrode for reading out accumulated signal electric charges from photo electric conversion elements to transfer channels in a reading out period and at a same time during the reading out period a second voltage is imposed 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 in a first mode for outputting signal electric charges independently, and only the first voltage is imposed only 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 in the second mode for adding the signal electric charges.
