Electronic device and method for adjusting volume

摘要

An electronic device and volume adjusting method detect ambient light and generate corresponding intensity signals via a sensor. Programs in a storage device, executed by at least one processor, cause the at least one processor to receive and sample light intensity signals and determine whether the ambient light level is changing. Time passing is counted if the ambient light level is changing, until the ambient light level stops changing. The counting of time stops when ambient light level stops changing and the counted time period is compared with a preset time period, a longer time period causes a volume adjusting command to be sent to a playback output device.

主权项

1. An electronic device comprising:
at least one processor; at least one sensor configured to detect ambient light level and generate corresponding light intensity signals; and a non-transitory storage medium storing one or more programs, which when executed by the at least one processor, cause the at least one processor to:
receive and sample the intensity signals generated by the at least one sensor and obtain sampled signals;determine whether the ambient light level has changed by comparing the intensity values of two adjacent sampled signals;start to count the passing of time if the ambient light level has changed;determine whether the changing of the ambient light level has stopped by comparing the intensity values of two adjacent subsequently sampled signals;stop counting the passing of time if the changing of the ambient light level has stopped;compare the counted passing of time with a preset time period and obtain a first compare result; andgenerate a first volume adjusting command according to the first compare result, and send the first volume adjusting command to an output device of the electronic device to control the output device to adjust volume.
