摘要： A camera system comprises a brightness measuring circuit, a exposure line choosing circuit, an operable switch, a film driver and a film driving mode selector.The brightness measuring circuit measures brightness of a photographic scene to send a brightness value. The exposure line choosing circuit chooses one of a plurality of exposure lines in which each lines selects a combination of an aperture value and a shutter speed value at each brightness value. The film driver drives a film in either of a first mode in which the film is wound only one frame in response to the operation of the operable switch and a second mode in which the film is wound frame by frame continuously as long as the operable member is operated. The film driving mode selector selects one of the modes in accordance with the exposure line chosen by the choosing circuit.In the camera system, a photographer may only select the exposure mode in accordance with his intention and purpose in photography, and then the film driving mode corresponding to the intention and purpose is automatically selected.

摘要： A camera system comprises a selector, an operable switch, a changing circuit and an inhibiting circuit. The selector selects one of a plurality of exposure lines. The changing circuit change as combination of the aperture value and the shutter speed value determine by both the selected exposure line and a brightness value in response to the operation of the operable switch. The inhibiting circuit inhibits the operation of changing circuit when a predetermined exposure line is selected by the selector. In the camera system, a photographer may only select the exposure mode through the operable switch in accordance with his intention and purpose in photography, and then the change of the exposure combination is inhibited in a certain exposure mode.

摘要： A camera includes an object distance detecting device. The detected object distance can be used to calculate magnification which, in turn, can be used to determine an aperture value. The object distance detecting device can be selectively operated depending on, for example, whether flash lighting is being used.

摘要： A winding and rewinding apparatus for a camera comprises a winding mechanism, a detector, a rewinding mechanism, a selector and a controller. The winding mechanism winds the film frame by frame, and the detector detects the completion of exposure of the roll of film which is wound by the winding mechanism. The rewinding mechanism rewinds the film automatically in response to the detection of the detecting means. The selector includes a selecting switch which is operable manually, for selecting in response to the operation of the selecting switch one of a first mode in which the operation of the rewinding mechanism is permitted and a second mode in which the operation of the rewinding mechanism is inhibited irrespective of the detection of the detector. The controller controls the rewinding mechanism in accordance with the mode selected by the selecting switch. According to such arrangement, the user can select a manual rewinding mode or an automatic rewinding mode by a simple operation.

摘要： An camera system includes a body and an accessory which is attachable to the camera body. A controller is provided in the camera body for controlling camera function. And an operable switch is also provided in the camera body. A function data concerning with camera function is sent from the accessory to the camera body. The camera body receives the function data and determines in response to the operation of the operable switch whether or not the controller controls camera function based on the received function data. According to the camera system, it is possible to enable or disable the camera function depending on the accessory by simple operation with the accessory attached to the camera body.
