Claim 1:
2. A far infrared sensor package, comprising:
a package body; and
a plurality of far infrared sensor array integrated circuits, disposed on a same plane and inside the package body, wherein each of the far infrared sensor array integrated circuits includes a far infrared sensing element array of a same size;
wherein a first far infrared sensor array integrated circuit of the plurality of far infrared sensor array integrated circuits includes a first sensing control circuit, and the first sensing control circuit performs a compensation computation according to a plurality of sensed signals derived respectively from a plurality of far infrared sensing element arrays; and at least one second far infrared sensor array integrated circuit of the plurality of far infrared sensor array integrated circuits includes a second sensing control circuit; and a function providable by the first sensing control circuit is different from functions providable by the second sensing control circuit; each of the first sensing control circuit and the second sensing control circuit includes a computation circuit for compensation computation, and only one of computation circuits of the first sensing control circuit and the second sensing control circuit is enabled.
