A camera comprising a first calculation means for calculating aperture value information based on exposure value information EV from the means and shutter time information set by the first photographing information setting means, the program mode setting means ; , program curve setting means for setting the slope α of the program curve;
a second calculation means for calculating shutter second information based on the exposure value information EV and the slope α of the program curve set by the program curve setting means; and when a program mode is set by the program mode setting means; After operating the second calculation means to calculate shutter time information, the output of the second calculation means is input to the first calculation means in place of the shutter time information from the first shooting information setting means. A camera characterized by being provided with a control means for calculating a value. The brief description of the drawing has been amended as follows. Page 32 of the specification, line 17 “Block diagram,”
is corrected to ``Block diagram. Figure 1-a is a functional block diagram showing the configuration of the present invention.''

Claims

[Scope of utility model registration request]

Program shooting mode and at least one AE
What is claimed is: 1. A camera that is capable of setting a shooting mode, and further comprising means for executing calculations in the program shooting mode and calculations in the AE shooting mode using the same calculation circuit.
