    摘要: 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.

    摘要: A camera having a zoom lens. The camera includes a shutter, an aperture and program exposure mode control. The program exposure control includes one or more reference program characteristics representing combinations of shutter speed and aperture corresponding to one or more of a portrait mode, a landscape mode and a close up mode. Each reference program characteristics define a predetermined aperture in a first range from a low shutter speed to a hand-induced vibration limit and defines a different aperture in a second range beyond the hand-induced vibration limit. One of the reference program characteristics is selected, wherein the hand-induced vibration limit is defined in accordance with a focal length of said zoom lens.
