Abstract

A camera wherein exposure parameters fixed by a program line can be shifted along an exposure value EV line so that exposure parameters for an exposure operation are based on the shifted program line according to the preference of the camera user. The camera has setting means for temporarily changing these exposure parameters at a constant exposure value with respect to the values predetermined by a program line. A counting means counts the number of times that a shutter is released while the program line is shifted in one direction and control means stores the changed values for shifting the program line under certain conditions. In this way a learning function is provided to learn the aforementioned tendency of the user.
