Abstract: 1458400 Cameras SEIKO KOKI KK 8 Aug 1974 [24 Aug 1973] 35010/74 Heading G2A [Also in Division G4] In a camera prior to exposure, a counter 6 counts fixed frequency pulses for a time dependant on subject brightness and exposure time is subsequently controlled in accordance with the count attained; the counter comprising a sequence of binary counting stages F 1  ... F n  followed by a holding stage F o  arrranged, when inverted by signals from the preceding stage, to maintain its inverted state even if further signals are fed to it from said preceding stage. This limits the size of the count and thus the complexity of the counter. As shown, counter 6 comprises flip-flop counting stages F 1  ... F n  connected by signal switching circuits f 1  ... f n , detailed in Fig. 3, (not shown). Initially the output Q o  Q o  of holding stage F o  (see Fig. 6) are O and 1. When the last binary stage F n  inverts, the outputs An An of switching circuit f n  change to 1 and O. This turns on a gate 6-21 through which the Q o  O output passes to an inverter 6-27 to produce a O at the output of a NAND gate 6-25. Counting continues and when F n  inverts again An An change to O and I . This turns on a gate 6-23 and the O of NAND 6-25 passes through gates 6-23, 6-31 to an inverter 6-28 to change Q o  to 1 and Q o  to O. This turns on an FET 6-30, whereby the Q O output passes through 6-30, 6-29, and inverter 6-28 to maintain the output of the latter at 1. Also the Q o  1 output turns off gate 6-31 blocking off NAND gate 6-25 to keep Q o  and Q o  at 1 and O despite further counting. Preferably counter 6 is connected to a display circuit 5, detailed in Fig. 7, (not shown) having lamps or light emitting diodes L 1  - L n , L o  indicating shutter speeds, under and over exposure, and "overflow" when Q o  Q o  become 1 and O.
