发明名称 EXPOSURE TIME DISPLAY DEVICE FOR FLASH PHOTOGRAPHING
摘要 PURPOSE:To make the visual confirmation of exposure time display easier at the time of flash photographing, by blinking a corresponding LED in accordance with the comparison between a computed exposure time and a prescribed exposure time which can be synchronized with flash. CONSTITUTION:A flashing preparation completed condition of a flashing apparatus 46 is discriminated by circuits 33-35, and one state out of two states is selectively designated by means of a manual selecting means S9. When the completion of the flashing preparation is discriminated and one state is designated by the means S9, display controlling circuits 52, 64-68 blink an LED 40i which can be synchronized with flash irrespectively of the computed exposure time from a photometry operating circuit 2. When the completion of the flashing preparation is discriminated and the other state is designated by the means S9, display controlling circuits 53, 60, 62-65 blink an LED 40i corresponding to a condition where the computed exposure time is shorter than a prescribed exposure time or another LED 40i corresponding to another condition where the computed exposure time is longer than a prescribed one.
