Electronic Device and Method for Controlling Electronic Device

摘要

An electronic device including a submersion detector, illuminants, a lighting circuit, a controller, and an orientation detector. The submersion detector detects submersion of the device and detect retrieval of the device. The illuminants are arranged inside a casing such that at least one of the illuminants is visible from above water when the device is submerged in any submersion orientation. The lighting circuit lights up at least one of the illuminants in response to an input of a lighting signal. The controller generates and outputs the lighting signal to the lighting circuit for a period of time from the submersion at least until the retrieval so as to light up the at least one of the illuminants. The orientation detector detects a submersion orientation of the device. Only the at least one of the illuminants that is visible from above water lights up, in accordance with the detected submersion orientation.

主权项

1. An electronic device comprising:
a submersion detector configured to detect submersion of the electronic device and detect retrieval of the electronic device, wherein the submersion means that the electronic device itself falls onto a surface of water or into water, and the retrieval means that the electronic device itself is retrieved from the surface of the water or from under the water; a plurality of illuminants provided inside a casing and arranged such that at least one of the illuminants is visible from above water when the electronic device is submerged in any submersion orientation; a lighting circuit configured to light up the at least one of the illuminants in response to an input of a lighting signal; a controller configured to generate and output the lighting signal to the lighting circuit for a period of time from the submersion at least until the retrieval so as to light up the at least one of the illuminants; and an orientation detector configured to detect a submersion orientation of the electronic device, wherein only the at least one of the illuminants that is visible from above water lights up, in accordance with the submersion orientation of the electronic device detected by the orientation detector.
