PURPOSE:To obtain a solid-state image pick-up device enabled to pick up an image by either of visible rays or infrared rays by a method wherein an infrared detector is jointly provided to the light receiving part. CONSTITUTION:When the title device is to be used by visible rays, transfer gates 6 are made to be in OFF condition to separate infrared detectors 5 from light receiving parts 1. When visible rays are irradiated to the CCD devices of the light receiving parts 1, electric charge patterns corresponding to light images are formed according to voltages applied to the electrodes of the CCD devices, and taken out as video signals from an output part 4 through storage parts 2 and a read-out register 3. When infrared rays are irradiated, the rays are absorbed by the infrared detectors 5, and electric charge patterns corresponding to the light images are formed in the infrared detector 5 group. After light is received for the prescribed hours, the transfer gates 6 are made to be in ON condition, electric charges formed by the infrared detectors 5 are transferred to the CCD devices of the light receiving parts 1, and taken out as video signals from the output part 4 through the storage parts 2 and the read-out register 3. |
