An electronic device includes an open-close detector configured to detect an open-close state indicating whether an optical path open-close device of a film camera is open or closed, a displacement detector configured to detect a displacement of a movable portion of the film camera interlocked with a movement of an operation portion of the film camera, and control circuitry. In response to a detection result of the displacement detector, the control circuitry selects a measurement mode for measuring an open time during which the optical path open-close device is open, from a plurality of operation modes of the electronic device. In the measurement mode, the control circuitry measures the open time based on the open-close state detected by the open-close detector.

The present invention provides a board mountable system for filming underwater video. The inventive board mountable system can be mounted to the underside of water vehicles for incorporating a camera for filming from an underwater perspective. The inventive board mountable system is shaped to minimize drag as a result of the mounted camera or camera system. Embodiments of the inventive system includes a fin shaped housing for holding a camera or camera system. In certain embodiments, the fin is removably attached to the water vehicle, such as a surf board, where the fin housing can be swapped with other fins being used with the water vehicle for controlling the direction of a watersports board in motion. These embodiments of the inventive system further include a connection means for connecting the fin to the underside of a water vessel.
