no. 1 Embodiment approach

[0052] figure 2 It is a figure explaining the structural example of the camera system of 1st 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 attached to the camera body 300 . In addition, the camera body 300 is configured so that the lens unit 200 can be detached, and the lens unit 200 can be mounted by fitting the unillustrated mounting connection part provided on the lens unit 200 and the non-illustrated mounting connection part provided on the camera body 300 to 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 at the mounting connection parts are also electrically connected to each other, enabling communication between the lens unit 200 and the camera body 300 via the contact 400 .

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

no. 2 Embodiment approach

[0112] Next, a camera system according to a second embodiment will be described. In addition, in this description, the same code|symbol is attached|subjected to the same component as the camera system 100 of 1st Embodiment, and it demonstrates.

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

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

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

no. 3 Embodiment approach

[0148] Next, a camera system according to a third embodiment will be described. In addition, in this description, the same code|symbol is attached|subjected to the same component as the camera system 100 of 1st Embodiment, and it demonstrates.

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

[0150]Along with this, the shake correction microcomputer 350 performs an operation for canceling the image shake of the imaging device 320 based on the angular velocity detected by the yaw rate sensor 360a and the pitch rate sensor 360b, or based on the angular velocity detected by the pitch rate sensor 360b. The control of the imaging device driving unit 330 moving in ...

Abstract

A camera system comprises a lens unit and a camera body. The camera body has a shake detection unit that detects shake in a plurality of directions, an image stabilization unit that performs image stabilization in a plurality of directions, a determination unit that determines whether or not the mounted lens unit is one that is capable of image stabilization, and an image-stabilization control unit that controls the image stabilization unit so as to perform image stabilization in only a specific one of the abovementioned plurality of directions if the determination unit has determined that the lens unit is one that is capable of image stabilization and controls the image-stabilization unit so as to perform image stabilization in the abovementioned plurality of directions if the determination unit has determined that the lens unit is not one that is capable of image stabilization.

Description

technical field [0001] The present invention relates to a camera system including a lens unit and a camera body configured to allow detachable attachment of the lens unit, and more particularly to a camera system having a camera 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") for correcting image shake caused by hand shake, etc. It is also possible to capture a good image without image shake. [0003] For example, there are two cases in the camera system of an interchangeable lens camera in which a photographic lens can be replaced according to a photographic purpose: a case where the hand-shake correction function is mounted on the interchangeable lens and a case where the hand-shake correction function is mounted on the camera body. Condition. When the hand shake c...
