Claim 18:
19. A vehicle camera, comprising a camera module, a memory and a processor, the camera module is configured for capturing optical images, the memory is configured for storing the optical images, the processor is configured for processing the optical images, and the camera module comprising:
a lens barrel, having a light entrance;
a first lens, disposed at the light entrance and having an image side surface;
a front cover, engaged with the lens barrel and the first lens;
a circuit board, having a positive terminal and a negative terminal; and
a heating element, having an annular heating portion, a first conductive column and a second conductive column, the annular heating portion is in contact with the image side surface and comprises a first heating terminal and a second heating terminal, the first conductive column is electrically connected between the first heating terminal and the positive terminal, and the second conductive column is electrically connected between the second heating terminal and the negative terminal;
wherein the image side surface of the first lens comprises an optical-effective lateral portion and a non-optical-effective lateral portion surrounding the optical-effective lateral portion, the non-optical-effective lateral portion is an edge region of the first lens, and the heating element is disposed only at the non-optical-effective lateral portion;
the heating element comprises a heating film and a buffer layer, both the heating film and the buffer layer are annular, the heating film is attached to the image side surface of the first lens, and the buffer layer is positioned between the heating film and the lens barrel; and the heating film comprises two electrical insulating films and a heating resistor layer, the heating resistor layer is sandwiched between the two electrical insulating films.
