发明名称 Camera system and camera body
摘要 This camera system includes: a vibration compensation unit including a vibration compensation optical system and an image-capturing unit; a drive unit that drives the vibration compensation unit; a detection unit that detects vibration; a position detection unit that detects the position of the vibration compensation unit; a target position determination unit that determines a target position for the vibration compensation unit according to the vibration of the camera; a calculation unit that calculates a drive amount for the drive unit; a range of movement limitation unit that limits the position of the vibration compensation unit within a range; a range setting unit that sets a movement permitted range that is within the range in which the vibration compensation unit can be positioned; and a centering unit that controls the drive unit so that the vibration compensation unit is centered in the center of the movement permitted range.

主权项 1. A vibration compensation device, comprising: a vibration compensation unit that comprises at least one of a vibration compensation optical system that makes an optical axis variable, and an image capturing unit that can be shifted, and that compensates image vibration upon an image surface occurring due to vibration of a camera; a drive unit that drives the vibration compensation unit; a detection unit that detects vibration of the camera; a position detection unit that detects the position of the vibration compensation unit; a range setting unit that sets within a first range that is a range of movement in which the vibration compensation unit can be mechanically positioned, a second range of movement; a target position determination unit that determines a target position for the vibration compensation unit within the second range according to vibration of the camera detected by the detection unit; and a control unit that controls the drive unit based upon the target position determined by the target position determination unit, thus compensating the image vibration, wherein the range setting unit changes a size of the second range based upon either or both of photographic states and photographic conditions.
