  • Patent number: 11513324
    Abstract: A camera module includes a circuit board; an image sensor mounted on the circuit board and electrically connected with the circuit boards, the image sensor comprising an array of focal planes; a barrel mounted on the circuit board with a cavity formed between the barrel and the circuit board, the image sensor being received in the cavity; and a lens stack array mounted to the barrel and spaced from the image sensor, the lens stack array comprising a plurality of first lens stacks, second lens stacks, third lens stacks, each of the lens stacks corresponding to one of the focal planes. The first lens stacks, the second lens stacks and the third lens stacks have different field of view and are combined in a single camera module, which enables a compact solution in a form of single camera module that traditionally requires multiple camera modules.
