Abstract
An electronic device, comprising: a first light source, configured to emit first light; a second light source, configured to emit second light; an optical sensor, configured to sense optical data generated according to reflected light of the second light or according to reflected light of the first light; and a control circuit, configured to analyze optical information of the optical data. If the control circuit determines variation of the optical information is larger than a variation threshold, the control circuit controls the first light source to be non-activated and the second light source to be activated.
