Abstract: Provided is an imaging apparatus which corrects uneven exposure caused when a sensor-shift image stabilization and an electronic front curtain reset are used concurrently. The imaging apparatus includes: a camera shake detector configured to detect a camera shake; an imaging device configured to capture a subject image; an image stabilizer configured to move the imaging device in a plane perpendicular to an optical axis; an electronic front curtain configured to reset electric charges accumulated in the imaging device; a mechanical shutter configured to switch between blocking and passing of a subject image to be collected onto the imaging device; and an image stabilization controller configured to produce an image stabilization signal from the camera shake detected by the camera shake detector and configured to control the image stabilizer. The image stabilization controller controls the imaging device to move to a specified position and then controls the electronic front curtain to operate in response to the shooting instruction.

Abstract: An imaging apparatus has one of the interchangeable lens and the camera body acting as a master and the other acting as a slave. The master has a shake detection unit configured to detect a shake of the camera body and/or the interchangeable lens; and a shake correction processing unit configured to calculate an amount of shake correction for the correction lens and the imaging device based on an output from the shake detection unit. The shake correction processing unit performs arithmetic processing for calculating a shake correction signal and separates the shake correction signal into a low frequency domain and a high frequency domain. One of the lens driving unit and the device driving unit performs the image blur correction based on the shake correction signal of the high frequency domain, and the other performs the image blur correction based on the shake correction signal of the low frequency domain.
