|4059835||Bypass circuits for improving the response of electric shutters|
An electric shutter circuit employs a photodiode which forms the collector load of a logarithmic amplifier. The photodiode is shunted with an active device which is caused to conduct during shutter operation to supply an additional current to the logarith...
|4041506||Timing circuits for camera shutters|
A memory capacitor in an electric shutter circuit has one terminal coupled to a voltage responsive element such as a diode, which operates to effectively reduce the level to which the capacitor is charged to thereby attain a decrease in discharge time of ...
