Abstract

PURPOSE: To obtain an image sensor which has a pickup function and a memory function both and can attain random access.
CONSTITUTION: Photoelectric cells 11 to 23 are of MOS structure and made of a semiconductor substrate, a clear electrode and an insulation film between the both; a depletion layer is formed by a voltage applied to this electrode and charges are accumulated in the corresponding depletion layer according to the quantity of light supplied via the clear electrode. Those cells are provided with charge transfer gate electrodes T11 to T23 which are of the same constitution and have no photosensitive functin. A voltage is applied to conductors S1, S2... to project a photo image on the group of cells, so that charges will be accumulated in depletion layers of respective cells. When a voltage is applied to one of conductors W1 to W3, the charge of a cell selected via conductors B1, B2... is read out to regeneration circuit F2 and then converted into a binary signal by binary-coding circuit N. With the quantity of light more than a certain value, the read-out output supplies charges to cells via switch SW2.
