ABSTRACT:
An endoscope apparatus includes an endoscope that has a solid-state image-pickup device in which charges are accumulated in order to pick up an object image. The endoscope apparatus further comprises a memory in which a plurality of pieces of information on the accumulation period during which charges are accumulated in the solid-state image-pickup device is stored, and a drive unit that controls the accumulation period, during which charges are accumulated in the solid-state image-pickup device, on the basis of the pieces of information on the accumulation period stored in the memory. The endoscope further includes an optical member whose surface is shaped rotationally asymmetric. Correction information stored in a memory and associated with the optical element is used to correct an output signal of the solid-state image-pickup device.
