Abstract: An endoscope camera head includes: an image pickup device that is configured to capture an image of an optical image and output an imaging signal containing the captured image; and a lens member that includes a lens for forming the optical image on the image pickup device, wherein the image pickup device is fixed to the lens member at a position in which the center of an image circle of the lens and the center of an image pickup area of the image pickup device coincide with each other.

Abstract: According to one embodiment, a driving apparatus for a solid-state image pickup element includes a generating unit configured to generate a drive voltage having an amplitude to obtain a predetermined multiplication gain to an electron-multiplying solid-state image pickup element, a calculating unit configured to calculate a change amount obtained when the multiplication gain of the solid-state image pickup element changes depending on elapsed time and conditions in actual use, and a correcting unit configured to correct an amplitude of the drive voltage output from the generating unit to obtain a predetermined multiplication gain on the basis of the change amount calculated by the calculating unit.
