Camera body and imaging device
View Patent ↗A camera body ( 3 ) includes a display unit ( 20 ) and a body microcomputer ( 10 ). The display unit ( 20 ) is able to display a zoom display bar ( 105 ) that expresses the focal length of the optical system (L). The body microcomputer ( 10 ) controls the display unit ( 20 ) so that the direction in which a zoom ring ( 64 ) moves when the user operates the zoom ring ( 64 ) substantially coincides with a change direction in which the zoom display bar ( 105 ) shown on the display unit ( 20 ) changes according to the operation of the zoom ring ( 64 ).
1. A camera body used in an imaging device along with a lens barrel with which the state of an optical system can be varied by operating a operation member, said camera body comprising:
a display unit configured to display a state indicator that expresses the state of the optical system and a through image; and
a control unit configured to control the display unit so that a state indicator is displayed when the user operates the operation member, wherein
the lens barrel further has a memory unit configured to store lens information,
the lens information includes focal length information expressing the range over which the focal length of the optical system can be varied,
the state indicator has a display meter that expresses the focal length information and expresses the focal length of the optical system as numerical information,
the control unit is configured to control the display unit so that the state indicator is displayed when the operation member is operated, and a display of the state indicator is automatically cancelled after the operation of the operation member is ended.
2. A camera body used in an imaging device along with a lens barrel with which the state of an optical system can be varied by operating a operation member, said camera body comprising:
a display unit configured to display a state indicator that expresses the state of the optical system and a through image;
a control unit configured to control the display unit so that a state indicator is displayed when the user operates the operation member; and
a shutter button configured to be a two-position switch that can be pressed halfway or all the way down, wherein
the lens barrel further has a memory unit configured to store lens information,
the lens information includes focal length information expressing the range over which the focal length of the optical system can be varied,
the state indicator has a display meter that expresses the focal length information and expresses the focal length of the optical system as numerical information,
the control unit is configured to control the display unit so that a display of the state indicator is automatically cancelled when the shutter button is pressed halfway in a state of displaying the state indicator.
3. A camera body used in an imaging device along with a lens barrel with which the state of an optical system can be varied by operating a operation member, said camera body comprising:
a display unit configured to display a state indicator that expresses the state of the optical system and a through image; and
a control unit configured to control the display unit so that a state indicator is displayed when the user operates the operation member, wherein
the lens barrel further has a memory unit configured to store lens information,
the lens information includes object distance information expressing the range over which the object distance of the optical system at which the system is focused can be varied,
the state indicator has a display meter that expresses the object distance information and expresses the object distance of the optical system as numerical information,
the control unit is configured to control the display unit so that the state indicator is displayed when the operation member is operated, and a display of the state indicator is automatically cancelled after the operation of the operation member is ended.
4. An imaging device, comprising:
a lens barrel having a operation member, an optical system configured to form an optical image of a subject, and a state varying unit configured to change the state of the optical system according to the operation of the operation member; and
the camera body according to claim 1 .
