The present disclosure provides a lens, a photographing device, as well as a processing method, a device and a storage medium for lens humidity. The lens includes a lens body and a humidity sensitive color changing film. The humidity sensitive color changing film is attached to a detection area of a photographing surface of the lens body, and changes color when its humidity is greater than a humidity threshold, to change color of image corresponding to the detection area in a photographed image. By configuring the humidity sensitive color changing film, the present disclosure can efficiently and accurately detect the presence of interference factors, such as water and frost, on surface of the lens at a low cost, thereby facilitating the start and stop control of dewatering/defrosting function, and preventing these external interference factors from adversely affecting the clarity and accuracy of images photographed by an in-vehicle camera.
