An endoscope apparatus includes: an endoscope distal end portion including an optical system configured to form an optical image, an image sensor configured to generate an image signal in accordance with a predetermined frame rate when the optical image is input, and an actuator configured to move the optical system along an optical axis; and a controller electrically connected to the endoscope distal end portion and including an imaging circuit configured to acquire the image signal from the image sensor, a drive circuit configured to feed a drive voltage to the actuator, and a processor configured to control the imaging circuit and the drive circuit, detect a vertical blanking period of the image signal acquired by the imaging circuit based on the image signal, and control the drive circuit to gradually increase a voltage supplied to the actuator within the vertical blanking period.

Endoscope apparatus and method of controlling endoscope

An apparatus has a synchronizing signal generator to which a trigger signal is input and that outputs a first synchronizing signal and a second synchronizing signal based on the trigger signal, an image pickup unit that has an image pickup surface, performs a first image picking-up based on the first synchronizing signal, and performs a second image picking-up based on the second synchronizing signal, and an image pickup element tilting unit that changes the angle of the image pickup surface relative to the optical axis during a period after the first image picking-up and before the second image picking-up.

Image pickup apparatus

A first calculating section calculates an amount of camera-shake correction based on an amount of shaking of the image pickup apparatus which has been detected, when each of a first capturing and a second capturing is carried out. A second calculating section calculates at least an amount of optical tilt-displacement between the image pickup element and an object for the first capturing, which is necessary for the second capturing, and the second calculating section calculates one of an amount of shift by which some of the image pickup lenses and the interchangeable image pickup lenses are to be shifted in a predetermined direction, and an amount of change by which an angle of an image pickup surface of the image pickup element with respect to the optical axial direction is to be changed, while the first capturing and the second capturing are being carried out.
