Abstract

In a dual priority automatic exposure control camera in which the exposure control mode can be selected among aperture priority, shutter speed priority, program control and manual control, a mode change-over device is provided for selecting one of the exposure control modes. The mode change-over device includes a first signal generator which gives a first signal indicating whether the shutter speed is automatically controlled or manually selected, a second signal generator which gives a second signal indicating whether the aperture is automatically controlled or manually selected, and a mode discriminator connected with the two signal generators for discriminating the exposure control mode based on the combination of the first and second signals. The output of the mode discriminator is connected with an exposure control system to control the shutter speed and/or the aperture according to the discriminated mode of exposure control.
