发明名称 UNDERWATER CAMERA HOUSING WITH PROPER EXPOSURE CONFIRMATION DISPLAY FUNCTION AT STROBOSCOPIC PHOTOGRAPHING
摘要 PROBLEM TO BE SOLVED: To inform that exposure is proper right after photographing regardless of a photographing mode in the case of photographing by proper exposure by providing a circuit unit informing of the proper exposure by LED light emission or buzzer generation based on the detection of the signals of exposure OK and light emission stop from a camera. SOLUTION: This housing is provided with the circuit unit CB having a circuit to detect the signals of the exposure OK and the light emission stop from the camera, the circuit to inform of the proper exposure by the LED light emission and the buzzer generation based on the detection of the signal or the like. Then, a light emitter LED is provided at the rear end part of a connection terminal with a hot shoe electrical contact point so as to be seen from the waterproof finder of an underwater camera housing. Also, a buzzer generating body Bz is provided near the inner wall of the underwater camera housing so that generated sound is liable to be transmitted to the outside of the under water camera housing. Thus, it is informed that the exposure is the proper exposure right after the photographing regardless of the photographing mode in the case of the photographing by the proper exposure.
