Problems solved by technology

[0006] However, even in the camera system of Patent Document 1, there is a problem that it is difficult for the user to select which one of the camera shake correction function of the photographic lens and the camera body to use with a simple operation. Work
In addition, communication and control become complicated by determining the presence or absence of the shake correction function of both the photographic lens and the camera body, resulting in increased cost and decreased responsiveness to sequential operations of the camera system

no. 1 approach

[0038] FIG. 1 is a diagram showing the overall configuration of a camera system of a first embodiment.

[0039] The camera system shown in FIG. 1 is constituted by a photographic lens 100 and a camera body 200 which are detachably connected to each other.

[0040] The photographic lens 100 has an optical system having at least: a focus lens (focus lens) 101a that adjusts focus; a diaphragm 101b that limits the amount of incident light; and a correction lens 101c that changes the optical axis of incident light.

[0041] In addition, the photographic lens 100 has: a focus adjustment mechanism 102 for adjusting the focus by shifting the focus lens 101a along the optical axis; and a correction lens for displacing the correction lens 101c on a plane perpendicular to the optical axis or tilting the correction lens 101c Displacement mechanism 103; Actuator drive circuit 104 for driving aperture 101b, focus adjustment mechanism 102, correction lens displacement mechanism 103; The len...

no. 2 approach

[0192] FIG. 18 is a flowchart showing the shooting operation of the camera system of the second embodiment. Next, the anti-shake operation of the camera system of the second embodiment will be described based on this flowchart.

[0193] When the camera operation switch 213 is operated, for example, an interrupt signal is input to the system controller 204, and the MPU of the system controller 204 executes a program stored at a predetermined address in the FlashRom 216 based on the interrupt signal, and starts a shooting operation, etc. (step S1800 ).

[0194] In addition, the following processing is realized by the respective MPUs of the lens control computer 106 and the system controller 204 shown in FIG. Express as the subject of processing.

[0195] When the photographing operation starts, the system controller 204 checks whether the first release switch is turned on by the release switch 213a. Then, when the first release switch is not in the on state (off state), the p...

no. 3 approach

[0247] FIG. 20 is a diagram showing the overall configuration of a camera system of a third embodiment.

[0248] The camera system shown in FIG. 20 includes a photographic lens 100 and a camera body 500 that are detachably connected to each other.

[0249] The photographic lens 100 is the photographic lens explained in FIG. 1 . In addition, the camera body 500 is a camera body that further includes a display panel 501 that displays various shooting information and a viewfinder display unit 502 that displays shooting information in a viewfinder in addition to the camera body 200 described in FIG. 1 .

[0250] On the display panel 501, in addition to the display related to the anti-shake function of the taking lens 100 and the camera body 500 (hereinafter referred to as "anti-shake display 506"), the light metering mode, AF mode, and image quality mode are also displayed. , shutter speed, aperture value, remaining battery level, number of shots that can be taken, color space se...

Abstract

The invention provides a camera system. In the camera system where a taking lens and a camera body respectively comprise a image shake correction unit for correcting a shake, which occurs on an image on an image capturing surface due to a jiggle of the camera system at the time of shooting, the taking lens and the camera body respectively comprise a communication unit for making a communication between the taking lens and the camera body, and a control is performed so that the communication unit of the camera body transmits a lens operation suspension instruction when the image shake correction unit of the camera body is operated, and the operation of the taking lens is suspended when the communication unit of the taking lens receives the lens operation suspension instruction.

Description

technical field [0001] The present invention relates to a camera system in which a photographic lens and a camera body are detachable, and more particularly to a camera system capable of performing a shake correction operation by using part or all of the shake correction function provided in the photographic lens or camera body. Background technique [0002] In recent years, for the purpose of improving operability and the like, many camera systems having a camera shake correction function have been proposed. In addition, among camera systems in which a photographic lens and a camera body are detachable, camera systems have been proposed in which not only the camera body but also the photographic lens have a shake correction function that can operate independently. With such a system, it is possible to configure camera systems with various configurations depending on the application, such as when both the photographic lens and the camera body have the shake correction functi...
