Abstract:
1. A solid-state image sensor, comprising: a plurality of photoelectric conversion elements arranged in a matrix pattern in a pixel repetition region; a vertical transfer section configured to read charges from the photoelectric conversion elements to transfer the read charges in a column direction; a horizontal transfer section configured to receive the charges from the vertical transfer section to transfer the received charges in a row direction; and a transfer control section configured to control the charge transfer from the vertical transfer section to the horizontal transfer section, wherein the vertical transfer section has a plurality of vertical transfer channels extending in the column direction, and a plurality of vertical transfer electrodes formed over the vertical transfer channels, the horizontal transfer section has a horizontal transfer channel extending in the row direction, and a plurality of horizontal transfer electrodes formed over the horizontal transfer channel, and is formed by a plurality of transfer packets, the transfer packet includes adjoining two or more of the plurality of horizontal transfer electrodes, and correspond to adjoining two or more of the plurality of vertical transfer channels, the transfer control section has a plurality of unit control sections corresponding to the transfer packets, the unit control section has the vertical transfer channel and a plurality of control section electrodes formed over the vertical transfer channel, the control section electrodes include a signal charge accumulating electrode and a transfer inhibiting electrode, which are sequentially formed from a side of the vertical transfer section, the vertical transfer channels are independently connected to the horizontal transfer channel, and when stopping the charge transfer from the vertical transfer section to the horizontal transfer section, a high-level voltage is applied to the signal charge accumulating electrode, and a low-level voltage is applied to the transfer inhibiting electrode.
