PURPOSE:To send a voiceless sign to a person to be photographed by sending a high noticing tone right before a shutter is released. CONSTITUTION:A camera is used for diverse purposes and used frequently for sourvenir photography of tours, etc. In this case, a photographer sends some kind of sign to a person to be photographed. Namely, a short electronic tone, etc., is generated to let the person to be photographed know that the shutter is released snoon. This sign is large enough for all the people to be photographed to hear and this sign tone uses an artistic electronic tone or beautiful special tone. For example, not a buzzer or bell sound, but a beautiful characteristic tone having a 0.5sec period or intermittent tone such as bleep is employed. Further, the tone causes a disturbance in a wedding ceremoney, etc., so that the tone generation is stopped in those case. |
