Anti-fog camera and defogging method

The invention provides an anti-fog camera and a defogging method, an image processing circuit board (namely, a chip) in the camera is connected with a lens module through a heat conduction assembly made of a heat conduction material, so that heat generated by the image processing circuit board in operation is transferred to the lens module to have a heating effect on the lens module, so that the temperature of the lens module is always higher than the ambient temperature, and the lens is prevented from fogging. According to the anti-fog camera and the defogging method, the heating and defogging of the lens module is combined with the heat dissipation of the image processing circuit board, the heat emitted by the image processing circuit board in operation is used for heating the lens, so that a heating module does not need to be specially arranged in the lens module; the heat generated by the image processing circuit board is reutilized, so that the cost and the power consumption increase caused by the heatin
