Electronic device, photographing method and device and readable storage medium

The embodiment of the invention provides an electronic device, a photographing method and device and a readable storage medium, and belongs to the technical field of communication. The embodiment of the invention provides an electronic device, which comprises a camera module. The electronic device further comprises a lens decorating part. The camera module comprises a lens and at least two resonant cavities. The at least two resonant cavities are arranged on the lens decorating part in an overlapping manner; an adjusting part for adjusting the thickness of the resonant cavity is arranged in the resonant cavity; and under the condition that the thickness of each resonant cavity is the target thickness of each resonant cavity, only one transmission peak with the same wavelength is included between the resonant cavities. Therefore, only the transmission peaks with the same wavelength are required to correspond to the target optical wavelength, only the light with the target optical wavelength can be acquired by
