摘要： A camera having a manually actuable switch for temporarily shifting the camera to an optimum exposure value so that exposure factors, based upon a manually set shutter speed and a manually set aperture value, are replaced by optimum exposure factors based upon a metered brightness of the object to be photographed when the camera is set to a non-program exposure mode. A clear button associated with the camera functions as a manually actuable switch for temporarily shifting an exposure mode of the camera to another exposure mode when the camera is set to a hyper-manual exposure mode. In the hyper-manual exposure mode, a photographer sets exposure factors by actuating a Tv electronic dial and an Av electronic dial. Actuation of the clear button when the camera is set to the hyper-manual exposure mode causes the set exposure factors to be replaced with optimum exposure factors that are automatically calculated in accordance with an object brightness Bv. Thus, operating the clear button (manually actuable switch for temporarily shifting to another exposure mode) results in the mode of the camera being changed from a mode in which exposure factors are manually set by a photographer (via the setting of a shutter speed and an aperture value) to a mode in which optimum exposure factors are set based upon a calculation performed by a processor of the camera.
摘要翻译： 一种具有手动开关的照相机，用于临时将相机移动到最佳曝光值，使得基于手动设定的快门速度和手动设定的光圈值的曝光因子被基于对象的计量亮度的最佳曝光因子所替代 当相机设置为非程序曝光模式时要拍摄。 与相机相关联的清除按钮用作手动开关，用于当相机设置为超手动曝光模式时将相机的曝光模式临时移动到另一曝光模式。 在超手动曝光模式中，摄影师通过启动电视电子拨号盘和Av电子拨盘来设置曝光因素。 当相机设置为超手动曝光模式时，清除按钮的启动使得设置的曝光因子被替换为根据对象亮度Bv自动计算的最佳曝光因子。 因此，操作清除按钮（用于临时移动到另一曝光模式的手动开关）导致相机的模式从摄影者手动设置曝光因子的模式（通过快门速度和 光圈值）到基于由照相机的处理器进行的计算而设定最佳曝光因子的模式。

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.

摘要： An electronic control camera in which, when an electronic flash is used with the camera, the required exposure data is automatically set. In the electronic control camera to which the invention pertains, film sensitivity data and luminance data provided by a photometric unit are applied to a data processing unit, which utilizes those tow data values to control the shutter speed and/or the aperture value. Further, the data processing unit varies the shutter speed, the aperture value and/or the amount of light emitted by the electronic flash coupled to the camera in accordance with these two data values.

摘要： A photographing apparatus comprises an imaging sensor, a controller, and an exposure-mode-selecting device. The controller performs a photometric operation on a photographing subject and obtains a luminance value of the photographing subject based on the photometric operation. The exposure-mode-selecting device is used for selecting an exposure mode of the photographing apparatus that has a sensitivity priority AE mode. The photographing operation is performed with a sensitivity of the imaging sensor that is set by a user and a shutter speed and an aperture value that are calculated based on the luminance value and the sensitivity, while the photographing apparatus is in the sensitivity priority AE mode.
