ABSTRACT:
The disclosed automatic exposure control camera is capable of operating in various exposure modes. In the exposure mode control device, a number of selectable switches select one of a number of imaging effects. An exposure mode selector arrangement holds a signal corresponding to which of the switches is operated until the exposure is terminated. An exposure controller controls exposures in the different exposure modes and selects an exposure mode based on the signal from the exposure selector. Each of the switches has a pictograph as an indication of the imaging effect being selected by that switch. According to an embodiment of the invention, an indicator in the camera displays a pictograph representing the imaging effect to be obtained in the selected exposure mode on the basis of the signal from the exposure mode selector.
