ABSTRACT:
An audible indication system indicates, by sound, information relating to camera operation and/or exposure condition such as information that a self-timer is in operation, that the camera is operated by a remote control signal, that the brightness of an object to be photographed is in a blur-occurring range or so high as to require non-available shutter speed, or that an electronic flash is ready for firing. A control means is provided for controlling the volume of the sound in accordance with the information to be indicated such that the information to be recognized remotely from the indicator, such as the information of self-timer operation and remotely controlled camera operation, is indicated with sound of a loud volume, while the information to be recognized in the proximity of the indicator, such as warning of out-of-range object brightness and the ready condition of an electronic flash device, is indicated with sound of relatively low volume. Additionally, the frequency of the sound for the indication may be changed depending on the information to be discriminated.
