Camera with microprocessor

摘要

A camera having a microprocessor made receptive of various photographic informations through interrupt processing. The information at a higher priority level of said various photographic informations such as a release signal, a photometry start signal and a photometry introduction signal is fed to said microprocessor by the interrupting operation having a shorter period than that of the information at a lower priority level. The interrupt processing are periodic ones, and wherein an inequality of m<n holds when the information at the higher priority level of said various photographic informations is fed with a period m times as long as an interrupt period whereas the information at the lower priority level is fed with a period n times as long as said interrupt period.
