Imaging apparatus having image stabilization mechanisms

摘要

An imaging apparatus includes a camera body and an interchangeable lens. The camera body includes: an image sensor; an image sensor driver configured to drive the image sensor in a plane perpendicular to an optical axis; a sensor configured to measure a position of the plane; a shake detector configured to detect a camera body shake; and a first image stabilizer configured to correct the detected shake by driving the image sensor driver. The interchangeable lens includes: an image stabilization lens configured to adjust an optical path to correct a shake; an image stabilization lens driver configured to drive the image stabilization lens in a plane perpendicular to the optical axis; and a second image stabilizer configured to correct a shake, based on a position measured by the sensor of the camera body, by driving the image stabilization lens driver.

1. An imaging apparatus comprising:
a camera body; and an interchangeable lens, wherein the camera body includes:
an image sensor configured to capture a subject image;an image sensor driver configured to drive the image sensor in a plane perpendicular to an optical axis;a translational motion sensor, driven integrally with the image sensor, and configured to measure a translational motion of the image sensor in the plane perpendicular to the optical axis;a shift amount detector configured to measure a shift amount of the image sensor;a shake detector configured to detect a shake of the camera body; anda first image stabilizer configured to correct the shake, detected by the shake detector, by driving the image sensor driver, and wherein the interchangeable lens includes:
an image stabilization lens configured to adjust an optical path to correct a shake;an image stabilization lens driver configured to drive the image stabilization lens in the plane perpendicular to the optical axis; anda second image stabilizer configured to correct a shake by driving the image stabilization lens driver, so as to counteract the translational motion of the image sensor, that is measured by the translational motion sensor.
