Abstract
An information setting device for a camera which, according to various photographic modes of the camera, automatically sets either a valid mode in which changing of set information is permitted or an invalid mode in which changing of set information is not permitted.
Claims18
An information setting device for a camera, comprising:
- a first operation member;
- a second operation member which is different from said first operation member;
- a setting change means for changing the set content of a previously set first item of control information in response to unaccompanied operation of said first operation member, and for changing the set content of a previously set second item of control information which differs from said first item of control information in response to a specific coordinated operation of said first operation member and said second operation member together;
- an internal setting change means for changing the set content of said first item of control information when the set content of said second item of control information is changed to a predetermined content by said setting change means, based upon said predetermined set content of said second item of control information;
- a valid/invalid mode setting means for setting one of a valid mode which permits processing for change of the set content of said first item of control information, and an invalid mode which prohibits processing for change of the set content of said first item of control information;
- and
- a valid/invalid mode changeover means for changing over from said invalid mode to said valid mode when the set content of said second item of control information is changed to said predetermined content by said setting change means while said invalid mode is being set.

An information setting device for a camera, comprising:
- an operation dial;
- a function designation operation member which is different from said operation dial;
- a setting change section to which said operation dial and said function designation operation member are connected, and which changes the set value of shutter speed or aperture opening value in response to unaccompanied operation of said operation dial, and which changes the setting of exposure mode in response to a specific coordinated operation of said operation dial and said function designation operation member together;
- an internal setting change section which changes the set values of said shutter speed and aperture opening when said exposure mode is changed to a predetermined exposure mode by said setting change section, based upon said predetermined exposure mode;
- a valid/invalid mode setting operation member;
- a valid/invalid mode setting section to which said valid/invalid mode setting operation member is connected, and which in response to the operation of said valid/invalid mode setting operation member sets one of a valid mode which permits processing by said setting change section for change of the set value of shutter speed or aperture opening, and an invalid mode which prohibits processing by said setting change section for change of the set value of shutter speed or aperture opening;
- and
- a valid/invalid mode changeover section which changes over from said invalid mode to said valid mode when the set exposure mode is changed to said predetermined exposure mode by said setting change section while said invalid mode is being set.

An information setting device for a camera, comprising:
- an operation dial for shutter speed;
- an operation dial for aperture opening value;
- an exposure mode switch;
- a valid/invalid mode switch;
- and
- a control circuit to which said shutter priority operation dial, said aperture opening value operation dial, said exposure mode switch, and said valid/invalid mode switch are connected;
- wherein
- said control circuit:
- changes the set value of shutter speed in response to unaccompanied operation of said operation dial for shutter speed, changes the set value of aperture opening in response to unaccompanied operation of said operation dial for aperture opening value, and changes the set mode of exposure mode, which includes at least an automatic program exposure mode, a shutter speed priority exposure mode, and an aperture priority exposure mode, in response to a specific coordinated operation of said operation dial for shutter speed and said exposure mode switch together;
- and:
- in response to coordinated operation of said operation dial for shutter speed and said valid/invalid mode switch together, sets a shutter speed invalid mode with processing prohibited for changing of the set value of shutter speed when a shutter speed valid mode with processing permitted for change of the set value of shutter speed is set, and sets said shutter speed valid mode when said shutter speed invalid mode is set;
- and, in response to coordinated operation of said operation dial for aperture opening value and said valid/invalid mode switch together, sets an aperture opening value invalid mode with processing prohibited for changing of the set value of aperture opening when an aperture opening value valid mode with processing permitted for change of the set value of aperture opening value is set, and sets said aperture opening value valid mode when said aperture opening value invalid mode is set;
- and:
- when said exposure mode is changed to said program automatic exposure mode, if said aperture opening value invalid mode is set, changes over said aperture opening value invalid mode to said aperture opening value valid mode, if said shutter speed invalid mode is set, changes over said shutter speed invalid mode to said shutter speed valid mode, and changes the set values of shutter speed and aperture opening based upon said automatic program exposure mode;
- when said exposure mode is changed to said shutter speed priority exposure mode, if said aperture opening value invalid mode is set, changes over said aperture opening value invalid mode to said aperture opening value valid mode, and changes the set value of aperture opening based upon said shutter speed priority exposure mode;
- and when said exposure mode is changed to said aperture priority exposure mode, if said shutter speed invalid mode is set, changes over said shutter speed invalid mode to said shutter speed valid mode, and changes the set value of shutter speed based upon said aperture priority exposure mode.
