Electronic camera flash using control microcomputer - has read-only memory providing function parameters for different photographic conditions and function parameter display

摘要

The electronic flash functions are controlled by the microcomputer, with a display device for the controlled function. The microcomputer has a read-only memory holding the function parameters for each different photography condition, in the form of a data block which is read out to allow automatic setting of the corresponding parameters. Pref. the function parameters are held in an electronically erasable read-only memory, the selected parameter settings indicated by an alphanumeric liquid crystal display, together with the corresponding memory location number for the defined photography situation. ADVANTAGE - Simple read out of stored data even after long interval between flash being used.
