发明名称 Photographic light measuring device
摘要 In a photographic light measuring device, a light output signal representing light reflected from an object to be photographed is converted into digital signals. At least first and second setting means generate respective first and second digital set signals which are respectively variable in response to respective manual operations. Photographic exposure data signals are generated using the digital light signal and the first and second set digital signals such that indicating means can selectively indicate data commensurate with the first and second digital set signals.
