    摘要： A camera system comprises a brightness measuring circuit, a exposure line choosing circuit, an operable switch, a film driver and a film driving mode selector. The brightness measuring circuit measures brightness of a photographic scene to send a brightness value. The exposure line choosing circuit chooses one of a plurality of exposure lines in which each lines selects a combination of an aperture value and a shutter speed value at each brightness value. The film driver drives a film in either of a first mode in which the film is wound only one frame in response to the operation of the operable switch and a second mode in which the film is wound frame by frame continuously as long as the operable member is operated. The film driving mode selector selects one of the modes in accordance with the exposure line chosen by the choosing circuit.In the camera system, a photographer may only select the exposure mode in accordance with his intention and purpose in photography, and then the film driving mode corresponding to the intention and purpose is automatically selected.

    摘要翻译： 相机系统包括亮度测量电路，曝光线选择电路，可操作开关，胶片驱动器和胶片驱动模式选择器。 亮度测量电路测量摄影场景的亮度以发送亮度值。 曝光线选择电路选择多个曝光线中的一条，其中每条线选择每个亮度值的光圈值和快门速度值的组合。 电影驱动器以第一模式驱动电影，其中仅在可操作开关的操作下仅卷绕一帧的电影，以及第二模式，其中，只要可操作构件，薄膜就被连续卷绕 被操作 电影驱动模式选择器根据由选择电路选择的曝光线选择一种模式。 在照相机系统中，拍摄者只能根据摄影的目的和目的选择曝光模式，然后自动选择对应于意图和目的的电影驾驶模式。
