no. 1 Embodiment approach

[0052] figure 2 It is a diagram explaining a configuration example of the camera system of the first embodiment.

[0053] Such as figure 2 As shown, the camera system 100 of this embodiment includes a structure in which the lens unit 200 is mounted on the camera body 300. In addition, the camera body 300 is configured as a freely attachable and detachable lens unit 200, and the lens is formed by fitting an unshown assembly connection portion provided on the lens unit 200 and an unshown assembly connection portion provided on the camera body 300 with each other. Mounting of the unit 200 to the camera body 300. Thereby, the lens unit 200 is fixed to the camera body 300, and the terminals provided in the respective mounting connection portions are also electrically connected to each other, and communication between the lens unit 200 and the camera body 300 can be performed via the contact 400.

[0054] The lens unit 200 includes an optical system 210, an LCU (Lens Control Unit) 220...

no. 2 Embodiment approach

[0112] Next, the camera system of the second embodiment will be described. In addition, in this description, the same components as those of the camera system 100 of the first embodiment are denoted by the same reference numerals.

[0113] Picture 10 It is a figure which shows the structural example of the camera system of this embodiment.

[0114] Such as Picture 10 As shown, the camera system 100 of this embodiment is compared figure 2 In the camera system 100 shown, the camera body 300 further includes a 3-axis acceleration sensor 380 that detects accelerations in the X, Y, and Z directions.

[0115] Along with this, under the control of the system controller 340, the shake correction microcomputer 350 is based on the detection results of the yaw angular velocity sensor 360a, pitch angular velocity sensor 360b, roll angular velocity sensor 360c, and 3-axis acceleration sensor 380 or based on the detection result of the roll angular velocity sensor 360c. As a result of the calc...

no. 3 Embodiment approach

[0148] Next, the camera system of the third embodiment will be described. In addition, in this description, the same components as those of the camera system 100 of the first embodiment are denoted by the same reference numerals.

[0149] The camera system 100 of this embodiment has the same configuration as the camera system 100 of the first embodiment. However, in the camera system 100 of this embodiment, since the shake correction in the roll direction is not processed, there may be no structural elements required for the shake correction in the roll direction.

[0150] Along with this, the shake correction microcomputer 350 performs a method for making the imaging element 320 to cancel image shake based on the angular velocity detected by the yaw angular velocity sensor 360a and the pitch angular velocity sensor 360b, or the angular velocity detected by the pitch angular velocity sensor 360b. Control of the imaging element drive unit 330 moving in the direction.

[0151] In add...

Abstract

A camera system including a lens unit and a camera body, wherein the camera body has: an image shake detection section that detects image shake in multiple directions; an image shake correction section that performs image shake correction in multiple directions; a determination section that determines whether the attached lens unit is a lens unit that can perform image shake correction, and an image shake correction control section that, when determined by the determination section to be a lens unit that can perform image shake correction, The camera shake correction unit is controlled to perform image shake correction only in a specific direction among the plurality of directions, and when the determination unit determines that the lens unit is not a lens unit that can perform image shake correction, the image shake correction unit is controlled to perform image shake correction in the plurality of directions. Like shake correction.

Description

Technical field [0001] The present invention relates to a camera system including a lens unit and a camera body configured to freely attach and detach the lens unit, and more particularly to a camera system having a shake correction function for correcting image shake caused by hand shake or the like. Background technique [0002] In recent years, cameras equipped with a camera shake correction function (hereinafter also referred to as "hand shake correction function") that corrects image shake caused by hand shake etc. have become popular, and photographers even if they don’t pay much attention to hand shake during handheld shooting, It is also possible to take good images without image shake. [0003] For example, there are two cases in a camera system of a lens-interchangeable camera capable of changing the photographic lens according to the purpose of photography: the case where the hand-shake correction function is incorporated in the interchangeable lens and the case where th...
