Abstract: According to one embodiment, camera system includes interchangeable lens and camera body. Camera body includes image sensor; reception circuit configured to acquire, first lens information including distortion correction information for correcting distortion of image pickup optical system, and function indicating correlation between shape of distortion on image plane, which corresponds to driving amount of vibration reduction optical system, and shape of distortion on image plane, which corresponds to displacement amount between optical axis and image center of photographed image; and processer configured to calculate converted displacement amount by using function, and to execute distortion correction, based on distortion correction information and converted displacement amount.

Abstract: An image pickup apparatus includes: an angular velocity sensor configured to detect image blur in translation and rotation directions; an image stabilization microcomputer; an image pickup device drive actuator configured to cause the image pickup device to move to perform optical correction of image blur in the translation direction and, when necessary, image blur in the rotation direction; a system controller configured to perform electronic correction of cutting out a part of image; and a walking detecting portion configured to detect which of a walking state and a non-walking state of the image pickup apparatus, wherein in a case of the walking state, an amount of correction of the image blur in the rotation direction is caused to be smaller by the optical correction, and is caused to be larger by the electronic correction, compared with the non-walking state.

Abstract: A camera system including an interchangeable lens and a camera body, in which the camera body includes: a Roll blur correction range setting unit that sets a blur correction range in Roll directions of the camera body to be ?1 when the interchangeable lens mounted on the camera body cannot perform blur correction (in the Pitch directions and the Yaw directions) or that sets the range to be ?2 (??1) when the interchangeable lens can perform blur correction; a Pitch-Yaw blur correction range setting unit that sets blur correction ranges in the Pitch and Yaw directions of the camera on the basis of the set blur correction range in the Roll direction; and a blur correction ratio calculation unit that calculates a blur correction ratio of each of the interchangeable lens and the camera body when both of them perform blur correction.

Abstract: A tracking device includes an imaging part for repeatedly acquiring image data on a subject image, a tracking processing part for setting a tracking position based on first image data to perform tracking processing on a subject in the tracking position based on second image data, and a relative distance information calculating part for calculating relative distance information using (1) a determined information about a distance to the tracking position and (2) a determined information about a distance to a surrounding area around the tracking position. When the tracking processing part determines that another subject in the surrounding area is located at the closer range than the subject in the tracking position, the tracking processing part prohibits tracking processing.
