II, secondly: in step 2, whether frost fog exists on the lens or the protective cover plate is judged in an automatic identification mode of the camera module, if yes, a defrosting reminding signal is sent, and in step 3, the camera module is triggered to defrost in a manual mode.
The principle of the automatic identification mode is as follows: in the automatic focusing process of the camera module, if frost fog exists on the lens or the protective cover plate, the frost fog is equivalent to a shot object, and the shot object is too close to the lens and is not in the automatic focusing range, so that the camera module cannot realize automatic focusing, and at the moment, the frost fog exists on the lens or the protective cover plate; of course, other principles may be adopted to automatically identify the frost and fog, such as comparing gray scales of a shot picture or analyzing the amount of incident light. The specific algorithm for identifying frost and fog is already the prior art, and therefore, will not be described in detail here.
