The tip of the sheath distal from the location where it is coupled to the handle includes an illumination element, an image capture element and a deflection element, allowing the distal tip to be pointed in a selected direction.

An endoscope apparatus, includes: a memory configured to hold setting information about operations respectively of a first endoscope and a second endoscope; and a processor. The processor is configured to: when detecting switching of the endoscope to be used between the first endoscope and the second endoscope, read the setting information for the endoscope after the switching, and use the setting information for setting for operation of the endoscope after the switching; and when the setting for operation of the endoscope in use is changed, update the setting information for the endoscope in use, and based on the updated setting information for the endoscope in use, update the setting information for the endoscope not in use, and record, in the memory, the updated setting information.

An endoscope includes an insertion portion having a light source portion configured to emit illuminating light therefrom when inserted into a body cavity. An imaging portion is configured to capture an image in the body cavity. A transmission portion configured to transmit the image captured by the imaging portion. A battery is configured to supply electric power needed for endoscopic observation. A power control portion is configured to selectively control a supply of electric power to all of the light source portion, the imaging portion, and the transmission portion in a standby mode in which power consumption is reduced compared with a normal operation mode in which a supply of electric power is performed from the battery to all of the light source portion, the imaging portion, and the transmission portion.

An image pickup apparatus includes: an image pickup device including a plurality of pixels generating an image pickup signal corresponding to a light reception amount; a universal cable for transmitting electric power to the image pickup device; an AC-voltage-pulse-signal generation circuit provided on a proximal end side of the universal cable and generating an AC voltage pulse signal obtained by converting a positive voltage level and a negative voltage level of an inputted pulse signal into a predetermined positive voltage level and a predetermined negative voltage level, respectively, and outputting the AC voltage pulse signal to the universal cable; and a voltage adjustment circuit provided on a distal end side of the universal cable and converting the predetermined positive voltage level and the predetermined negative voltage level of the AC voltage pulse signal transmitted from the universal cable into a DC voltage level and output a DC voltage pulse signal.
