Abstract

The present invention provides a method for an electronic device. The method comprises: emitting emitted light; receiving reflected light of the emitted light and reflected light of ambient light; and according to the detected reflected light of the ambient light, determining the optimal frequency of the emitted light. The present invention also provides the electronic device.

Description

technical field [0001] The present invention generally relates to the field of optical technology, and in particular to a method for an electronic device and an electronic device. Background technique [0002] The optical touch system is a system that projects an optical signal corresponding to an image to be projected onto an area outside the system and recognizes a user's operation on the projected image by reflected light for light emitted from the optical touch system. The system has the advantages of saving space, being easy to carry, etc., and can respond quickly to detailed actions, so it is widely used in many scenes such as meeting places, exhibition places, and education and training places. [0003] However, there are many interference sources in various complex environments, and the frequencies of the interference sources may be the same or close to the frequency of the light emitted by the optical touch system, thus affecting the optical touch system's determina...
