Abstract
A camera including an exposure area switching mechanism for switching an exposure area by an actuating operation of an actuator which is electrically controllable, an exposure operation circuit for executing an exposure operation, and a control circuit for inhibiting, during the exposure operation of the exposure operation circuit, the exposure area from being switched by the actuating operation of the actuator of the exposure area switching mechanism.
Claims68
A camera comprising:
- a) an exposure area switching mechanism for switching an exposure area by operation of an electrically-controllable actuator in response to an operation by a user;
- b) exposure operation means for executing an exposure operation;
- and
- c) control means for inhibiting, during the exposure operation of said exposure operation means, the operation of said actuator of said exposure area switching mechanism in response to the operation by the user.
1 more element
A camera comprising:
- a) an exposure area switching mechanism for switching an exposure area by operation of an electrically-controllable actuator in response to an operation by a user;
- b) multiple exposure operation means for executing a multiple exposure operation;
- and
- c) control means for inhibiting, during a time interval in which said :exposure operation means executes said multiple exposure operation, an operation of said actuator of said exposure area switching mechanism in response to the operation by the user.
1 more element
A camera comprising:
- a) an exposure area switching mechanism for switching an exposure area by operation of an electrically-controllable actuator in response to an operation by a user;
- b) automatic exposure bracketing operation means for executing an automatic exposure bracketing operation in which a plurality of times of continuous exposures are performed while varying an amount of exposure;
- and
- c) control means for inhibiting, during a time interval in which said automatic exposure bracketing operation means executes said automatic exposure bracketing operation, the operation of said actuator of said exposure area switching mechanism in response to the operation by the user.
1 more element
A camera comprising:
- a) an exposure area switching mechanism for switching an exposure area by an actuating operation of an actuator which is electrically controllable;
- b) film advancement means for advancing a film;
- and
- c) control means for causing said exposure area switching mechanism to forcedly operate, during an operation of said film advancement means.
1 more element
A camera comprising:
- a) an exposure area switching mechanism for switching an exposure area by an actuating operation of an actuator which is electrically controllable;
- b) a back lid which can be opened and closed;
- c) detecting means for detecting whether said back lid is opened;
- and
- d) control means for causing said exposure area switching mechanism to forcedly operate, when said detecting means detects that said back lid is opened.
2 more elements
A camera, comprising:
- a) an exposure area switching mechanism for switching an exposure area by operation of an electrically-controllable actuator in response to an operation by a user;
- and
- b) control means for controlling said actuator so as to inhibit the operation of said actuator in response to the operation by the user on the basis of an operation state of the camera.
