DIGITAL LOW-LIGHT VIEWING DEVICE
First Claim
1. A low-light viewing device, comprising:
- a housing, having mounted thereto;
a lens having an F number of less than about 1, and a T number of less than about 1.5;
an electronic camera for receiving light focused by the lens and for providing an output signal responsive to visible light and near infrared light received by the lens;
a display for receiving the output signal and displaying an image detected by the camera;
a controller operatively coupled to the camera and the display for controlling the camera and the display, and a user interface operatively coupled to the controller for operating the controller.

Abstract
A low-light viewing device includes a housing, having mounted thereto: a lens, an electronic camera for receiving light focused by the lens and for providing an output signal; a display for receiving the output signal and displaying an image detected by the camera; a controller for controlling the camera and the display, and a user interface for operating the controller. The lens may be a fixed focus lens having an F number of less than about 1, and a T number of less than about 1.5. The display may have a resolution at least as great as the resolution of the camera. The device may have a processor programmed to provide control signals to the camera and display depending on a selected light environment.

11. A low-light viewing device, comprising:
-
a housing having a planar top surface;
opposing side walls which taper gradually outward from opposite edges of the top surface, and taper gradually inward to edges of a generally planar lower surface;a lens mounted on one end of the housing; an electronic camera within the housing for receiving light focused by the lens and for providing an output signal responsive to visible light and near infrared light received by the lens; a display for receiving the output signal and displaying an image detected by the camera and mounted on an end of the housing opposite the lens; a controller operatively coupled to the camera and the display for controlling the camera and the display, and a user interface defined in the top surface of the housing and operatively coupled to the controller for operating the controller; wherein the device is configured as a monocular. - View Dependent Claims (12, 13, 14, 15, 16)

17. A method for providing low-light viewing, comprising the steps of:
-
focusing, via a lens mounted on a housing, visible and infrared light on to a camera within the housing; receiving a user selection of light environment level at a user interface on the housing; providing control signals, based on the selected light environment, from a controller in the housing to the camera and to a display within the housing; implementing camera settings based on the control signals; providing, from the camera, an output signal indicative of a focused image; implementing display settings based on the control signals; and displaying an image based on the output signal at the display. - View Dependent Claims (18, 19, 20, 21)
