Abstract
A bracketing exposure control camera is structured in such a manner that a preset number of frames for bracketing photography is compared with the actual number of frames exposed so far in bracketing photography and exposure control operation is forcibly stopped upon detecting that the preset number of frames has been exposed. The bracketing exposure control camera can perform bracketing photography of a plurality of frames with a motor drive device, and will not waste film when the operator continues to depress the shutter release button after bracketing photography has been completed.
Claims8
A bracketing exposure control camera having exposure means for controlling an exposure operation of each of a plurality of film frames and exposure correction means for causing said exposure means to perform exposure operations of respective frames at different exposure values, comprising:
- driving means for winding said film after said exposure means is operated and for operating said exposure means after a winding operation, thereby alternately performing an exposure operation and a winding operation;
- frame number setting means for setting a given number of exposure frames;
- control means for operating said exposure correction means and controlling said driving means so that said exposure means performs exposure operations corresponding to said given number of exposure frames set by said frame number setting means;
- means for producing a frame signal indicative of a number of unexposed film frames;
- and
- detection means responsive to said frame signal for detecting that the number of exposure frames set by said frame number setting means is larger than the number of unexposed frames and for producing a detection signal.
A camera according to calim 6, which further comprises means for displaying said first exposure correction amount and said second exposure correction amount.
A motor driving camera having exposure means for controlling an exposure operation of each of a plurality of film frames comprising:
- driving means for winding said film after said exposure means is operated and for operating said exposure means after a winding operation, thereby alternately performing an exposure operation and a winding operation;
- frame number setting means for setting a given number of exposure frames;
- control means for controlling said driving means so that said exposure means performs exposure operations corresponding to said given number of exposure frames set by said frame number setting means;
- means for producing a frame signal indicative of the number of unexposed frames of said film;
- and
- detection means responsive to said frame signal for deteting that the number of exposure frames set by said frame number setting means is larger than the number of unexposed frames and for producing a detection signal.
