1. A method of displaying visible-light (VL) images and infrared (IR) images, the method comprising:

  • providing a camera having a VL lens with a VL sensor, an IR lens with an IR sensor, and a display, the VL lens and the IR lens being located on the camera such that an optical axis of the VL lens is offset from, and generally parallel to, an optical axis of the IR lens so the VL sensor and the IR sensor sense a VL image and an IR image, respectively, of a target scene from different points of view causing a parallax error;

    focusing the IR lens on the target scene, with the focusing of the IR lens operating to bring the VL image into register with the IR image to correct the parallax error; and

    displaying at least a portion of the VL image in register with at least a portion of the IR image on the display.
