摘要： An exposure control system for a photographic camera of the type provided with a shutter preselection automatic exposure range and a diaphragm preselection automatic exposure range, wherein various exposure control parameters are digitized and applied to a digital computer for providing either shutter interval or diaphragm aperture control signals. For exposure control in the shutter preselection automatic exposure range, there are provided a signal generator associated with the camera diaphragm mechanism, an analog-to-digital converter cooperative therewith for providing digital signals corresponding to ever varying aperture sizes as the diaphragm mechanism is operated from its fully open position, and a comparator connected between said computer and converter upon detection of coincidence of the signal from the computer with one of the signals from the converter to provide a diaphragm mechanism arresting signal. Further, the invention provides various types of non-contact device usuable as the diaphragm information generator.
