STROBE SYNCHRONIZED CAMERA SYSTEM

摘要

PURPOSE:To ease correct strobe photographing by displaying the over- and under- light emission quantities. CONSTITUTION:A decoder DE is connected via adder ADD 3 to two parallel adders ADD1, ADD2 and the LSI element 24 of the camera body is provided. The decoder DE is electrically connected to the light emission quantity display body 38 provided to a strobe device 33. As a result of this, ASA numerical value information and aperture numerical value information are supplied to the n-bit parallel adder ADD1 and distance numerical value information to the n-bit parallel adder ADD2. The distance numerical value information is doubled and is supplied together with the other information to the n-bit adder ADD3 where they are added. The results of the addition are converted to decimal information by the decoder DE and are then inputted to a guide number selection circuit 46. The under display part of the light emission quantity display body 38 is energized when the guide number information is larger than the maximum guide number of the strobe device 33 and the over display part when it is smaller.
