Abstract:
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, the IR lens being manually rotatable; displaying at least a portion of the VL image and at least a portion of the IR image on the display, the relative positions on the display of the at least the portion of the VL image and of the at least the portion of the IR image being controllable via rotation of the IR lens; and manually rotating the IR lens until the at least the portion of the VL image and the at least the portion of the IR image are positioned in register on the display to correct the parallax error, the registration via IR lens rotation focusing the IR lens on the target scene.
