Abstract: An imaging apparatus includes: an image sensor that captures a subject image formed via an optical system to generate image data; an optical image stabilizer including at least one of a first image stabilizer moving a correction lens, and a second image stabilizer moving the image sensor; a third image stabilizer that adjusts an area from which an image is cropped; and a controller that controls image stabilization by the image stabilizers, wherein the controller sets a shake correction amount of the optical image stabilizer; and sets a shake correction amount of the third image stabilizer, based on an error amount indicating a difference between the shake correction amount set to the optical image stabilizer and a displacement of the correction lens or the image sensor moved by the optical image stabilizer, and the third image stabilizer performs image stabilization based on the set shake correction amount.

Abstract: A controller of an imaging apparatus performs, if the controller can not obtain information on a focal length of an interchangeable lens from the interchangeable lens, the controller controls to perform an image stabilization operation using, as the focal length, an estimated focal length calculated based on at least one of a combination of a detected shake amount and an image motion amount in image data, or a combination of the detected shake amount and a motion amount of an image sensor. The controller controls whether to execute or stop the image stabilization operation by a first image stabilizer based on at least one of a correlation between the detected shake amount and the image motion amount, or a correlation between the detected shake amount and the motion amount of the image sensor.

Abstract: An imaging apparatus includes: an image sensor that captures a subject image via an optical system; a detector that detects a shake amount of the imaging apparatus; a calculation circuitry that performs a calculation for image stabilization, based on the shake amount detected by the detector; and an image stabilizer that performs the image stabilization by translational movement and rotational movement within a predetermined movable range of the image sensor, based on a result of the calculation by the calculation circuitry. The calculation circuitry changes a first maximum amount and a second maximum amount within the movable range, according to a result of successively calculating a shake correction amount, the first maximum amount allowing a first movement of the translational movement and the rotational movement, the second maximum amount allowing a second movement of the translational movement and the rotational movement.
