Abstract: An endoscope system includes an endoscope having a position/angle sensor and an amplifying circuit, a memory configured to store output error sensitivity data and a first wiring resistance value, and a processor including a signal processing circuit configured to process an output signal from the amplifying circuit. The signal processing circuit corrects an error of the output signal based on a value obtained by multiplying a difference between the first wiring resistance value and a processor wiring resistance value by the output error sensitivity data.

Abstract: A position detection apparatus is configured to detect a position of a movable portion relative to a fixed portion using a voice coil motor (VCM) driving portion. The position detection apparatus includes a position detection element arranged on one of the movable portion and the fixed portion, and a first position detection magnet and a second position detection magnet arranged on another of the movable portion and the fixed portion. The first position detection magnet and the second position detection magnet are aligned so that different magnetic poles face a surface of the position detection element. The first position detection magnet and the second position detection magnet are arranged in an order in a moving direction of the movable portion such that magnitudes of densities of magnetic fluxes reaching the surface of the position detection element from the first position detection magnet and the second position detection magnet are different.

Abstract: An imaging apparatus includes a camera shake correction unit which uses a coil and a magnet to move a movable portion including an image pickup device relative to a fixed portion. A position detection section detects the position of the movable portion. A setting section sets a resolving power of the detection of the position by the position detection section to a first or second resolving power which is a resolving power higher than the first resolving power and at which an amount of deviation from a target position is less than or equal to a pixel shift amount. A drive control section performs pixel shifts to move the movable portion with the second resolving power set by the setting section. A photography control section causes the image pickup device to perform exposures by timing of the pixel shifting and which composes images obtained by the exposures.
