PURPOSE:To make possible the changing-over from dot displaying to segment displaying of camera information by controlling flip-flops, etc. by signals for dot displaying via counters, etc. thereby forming signals for segment displaying. CONSTITUTION:The light emission of 32 pieces, etc. of LEDs is controlled by the signals T1-T8 which are always of the same period and are shifted in phases, and the state signals S0-S3 for 8Hz, 4Hz flickering and displaying put-out which are shifted in phases each other, whereby camera information is dot-displayed. With these signals T1-T8 as clocks, counters COUNT1-COUNT3 which are controlled by the signals S0-S3 count these and control setting, etc. of flip-flops FF1-FF3 by way of AND gates AND1-AND3. The outputs corresponding to the counting values of the annihilation times of the signals S0-S3 are generated and the camera information is changed over from dot displaying to segment displaying. Further, it is also possible to make dot displaying and segment displaying simultaneously. |
