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: An endoscope system includes an endoscope and a processor. The endoscope includes: an actuator including a coil configured to cause a movable lens and a magnet to move by application of a drive signal; a position sensor configured to output a position detection signal showing a position of the movable lens according to a magnetic flux of the magnet; and an endoscope memory storing correction information for correcting crosstalk onto the position detection signal by the magnetic flux of the coil. The processor includes a drive controller configured to correct the position detection signal based on the drive signal and the correction information and output the drive signal based on a target position and the corrected position detection signal, to the actuator.

Abstract: A camera shake correction apparatus includes a target position setting unit, a current setting unit, a driving unit, a magnetic flux detector, and an arithmetic unit. The target position setting unit sets a target position of a movable member. The current setting unit sets a current value to move the movable member to the target position. The driving unit drives the movable member with respect to a fixed member based on the set current set value. The magnetic flux detector detects a magnetic flux value changed with movement of the movable member. The arithmetic unit calculates a third magnetic flux value by subtracting a second magnetic flux value estimated to be generated from the driving unit based on the current set value from a first magnetic flux value actually detected by the magnetic flux detector.
