## Abstract

An imaging apparatus includes a shake correction unit, a pixel shift unit, and a controller. The shake correction unit includes a first movable unit and a first position detector, and moves the first movable unit based on outputs of a shake detector and the first position detector. The pixel shift unit includes a second movable unit and a second position detector, and makes a pixel shift correction by moving the second movable unit based on an output of the second position detector. The controller controls the shake correction unit to stop a center of the lens and held by the first movable unit at a position that matches the optical axis. The controller sets a gain for amplifying the output of the first position detector when performing shake correction to be higher than a gain for amplifying the output of the first position detector when making a pixel shift correction.

## Claims

### Claim 1

An imaging apparatus, comprising:
a shake correction unit that includes a first movable unit that holds part of a lens of an imaging optical system and a first position detector that detects a position of the movable unit, and moves the first movable unit in a direction perpendicular to an optical axis based on outputs of a shake detector and the first position detector;
a pixel shift unit that includes a second movable unit that holds an imaging unit and a second position detector that detects a position of the second movable unit, and makes a pixel shift correction by moving the second movable unit in the direction perpendicular to the optical axis based on a detection result of the second position detector; and
a controller that controls the shake correction unit to stop a center of the lens forming the shake correction unit and held by the first movable unit at a position that matches the optical axis based on the output of the first position detector when the pixel shift unit is driven,
wherein
when making the pixel shift correction, the controller sets a gain for amplifying the output of the first position detector when performing shake correction to be higher than a gain for amplifying the output of the first position detector when making a pixel shift correction.

### Claim 2 (depends on 1)

The imaging apparatus according to claim 1, wherein
when amplifying an output of the first or second position detector, the controller amplifies the output so that an output voltage of an amplifier is large with respect to a movement amount per unit of the first or second movable unit.

### Claim 3 (depends on 1)

The imaging apparatus according to claim 1, wherein
the pixel shift unit also has a shake correction function of correcting for the shake by moving the second movable unit in the direction perpendicular to the optical axis based on a detection result of the shake detector.
