A solid-state image sensor is disclosed which comprises a pn photodiode formed in a P-type substrate. A charge-coupled device is disposed adjacent the photodiode for receiving signal carriers from the diode. A lateral-overflow drain is disposed adjacent the photodiode for receiving carriers from the photodiode. In order to provide a simplified image sensor, a virtual gate is formed between the photodiode and the drain to effect the flow of excess carriers from the photodiode.
