Claims

[Scope of utility model registration request]

It is possible to set shooting information including the photometric value of the subject brightness and information on either the shutter time or aperture value, and obtain the appropriate exposure from these calculation results in shutter speed priority mode shooting and aperture priority mode shooting. In the camera, a priority mode changeover switch having a first mode of shutter speed priority mode shooting and a second mode of aperture front mode shooting;
a display section indicating the type of priority mode; a priority information input means for setting shutter time information when the first mode is selected by the switch, and aperture value information when the second mode is selected; From the signal of the priority information input means, when the second mode is selected by the priority mode changeover switch, shutter time information is calculated to obtain the appropriate exposure, and when the first mode is selected, the shutter time information is calculated so as to obtain the appropriate exposure. A single calculation means for calculating aperture value information to obtain exposure, and a signal from the calculation means when the first mode is selected by the priority mode changeover switch, and a signal from the calculation means when the second mode is selected. an aperture control means into which a signal from the information input means is input, a signal from the calculation means when the second mode is selected by the priority mode switch, and a signal from the calculation means when the first mode is selected; What is claimed is: 1. An exposure control device for a camera, comprising a shutter control circuit to which a signal is input.
