Embodiment approach 1

[0020] Hereinafter, Embodiment 1 in which the present invention is applied to an interchangeable-lens camera system will be described with reference to the drawings.

[0021] 1-1. Structure

[0022] 1-1-1. Overview

[0023] figure 1 It is a block diagram showing the configuration of the camera system 1 according to Embodiment 1 of the present invention. The camera system 1 is composed of a camera body 100 and an interchangeable lens 200 detachably attached to the camera body 100 . The camera system 1 is capable of automatic focus control by driving the focus lens 230 . In addition, the camera system 1 can perform aperture control by driving the aperture 260 . In this embodiment, in an interchangeable-lens camera system, a structure for smoothly transitioning from control of driving a movable member such as autofocus control or aperture control to other controls will be described.

Abstract

A camera system (1) includes an interchangeable lens (200) and a camera body (100). The camera body (100) includes a body controller (140) configured to generate a command, and a sending unit (150) configured to send the generated command to the interchangeable lens. The interchangeable lens (200) includes a movable member (230, 260), a driving unit (233, 261) configured to drive the movable member, a receiving unit (250) configured to receive a command from the camera body, and a lens controller (240) configured to control the driving unit according to the received command. Further, a prediction unit (140, 240) is provided in either one of the camera body and the interchangeable lens, which predicts whether an operation of the driving unit of the interchangeable lens according to the received command will be completed within a predetermined time.

Description

technical field [0001] The present invention relates to a camera system, in particular to a camera system composed of an interchangeable lens and a camera body. Background technique [0002] Patent Document 1 discloses a camera system composed of a camera body and an interchangeable lens. This camera system performs autofocus control by sending an instruction to control driving of the interchangeable lens from the camera body to the interchangeable lens. [0003] [Patent Document 1] Japanese Unexamined Patent Publication No. 2007-322922 [0004] In an interchangeable lens, it is necessary to perform various controls by the camera body in addition to the autofocus control, and therefore development of technology for transitioning from the autofocus control to other controls is expected. [0005] Patent Document 1 does not disclose any technique regarding transition from autofocus control to other controls. Contents of the invention [0006] The object of the present inve...
