Abstract

A camera system includes a first imaging sensor, a second imaging sensor, and a controllable mirror system. The mirror system includes a mirror disposed at a fixed position to the first imaging sensor and the second imaging sensor, and a controller to control a signal applied to the mirror. The mirror system transmits a first portion of incident light through the mirror to the first imaging sensor, and reflects a second portion of the light to the second imaging sensor. A method of producing color images includes receiving incident light on a surface of the mirror, controlling the mirror to direct a first portion of the light to a first imaging sensor and a second portion of the light to a second imaging sensor, receiving first imaging sensor data from the first imaging sensor, and receiving second imaging sensor data from the second imaging sensor.

Claims (44)

1. A camera system comprising:

a first intensified optical imaging sensor that provides first intensified optical imaging sensor data under low illumination conditions;

a second color optical imaging sensor that provides second color optical imaging sensor data under high illumination conditions;

an electronically controllable mirror system comprising:

an electronically controllable mirror disposed at a fixed position relative to the first intensified optical imaging sensor and to the second color optical imaging sensor; and

a mirror controller to control a mirror control signal applied to the electronically controllable mirror,

wherein the electronically controllable mirror system, based on the mirror control signal, transmits a first portion of incident light through the electronically controllable mirror to the first intensified optical imaging sensor, and reflects a second portion of the incident light by the electronically controllable mirror to the second color optical imaging sensor; and

a camera system controller comprising:

a processor; and

a memory unit, wherein the memory unit comprises instructions that, when executed by the processor, cause the processor to:

receive the first intensified optical imaging sensor data from the first intensified optical imaging sensor;

receive the second color optical imaging sensor data from the second color optical imaging sensor; and

merge the first intensified optical imaging sensor data and the second color optical imaging sensor data into enhanced color imaging data.

2. The camera system of claim 1 , wherein the memory unit further comprises instructions that, when executed by the processor, further cause the processor to:

calculate imaging data from characteristics of the first intensified optical imaging sensor data and characteristics of the second color optical imaging sensor data.

3. The camera system of claim 2 , wherein the memory unit further comprises instructions that, when executed by the processor, further causes the processor to transmit the imaging data to an image display system, a data storage system, or an external system.

4. The camera system of claim 2 , wherein the memory unit further comprises instructions that, when executed by the processor, further cause the processor to:

transmit a mirror controller regulator signal to the mirror controller based at least in part on the first intensified optical imaging sensor data or the second color optical imaging sensor data.

5. The camera system of claim 2 , wherein the memory unit further comprises instructions that, when executed by the processor, further causes the processor to:

receive a manual operation signal from a user-operated input device; and

transmit a manual mirror controller regulator signal to the mirror controller.

6. The camera system of claim 2 , wherein the memory unit further comprises instructions that, when executed by the processor, further causes the processor to:

receive an input signal from an external device; and

transmit an input data mirror controller regulator signal to the mirror controller.

7. The camera system of claim 1 , wherein the electronically controllable mirror comprises a surface spatially fixed with respect to a body of the electronically controllable mirror to receive the incident light.

8. The camera system of claim 1 , wherein the electronically controllable mirror is continuously adjustable between a maximum percent transmittance state and a minimum percent transmittance state, and

The camera system of claim 1 , wherein the first intensified optical imaging sensor is capable of providing the first optical imaging data under illumination of between about 1×10 −6 foot-candles and about 1×10 −3 foot-candles and wherein the second color optical imaging sensor is capable of providing the second optical imaging data under illumination of between about 1×10 −3 foot-candles and about 1×10 3 foot-candles.

13. A method of producing color images, the method comprising:

receiving incident light on a surface of an electronically controllable mirror;

controlling, by a camera system controller, the electronically controllable mirror to direct a first portion of the incident light to impinge on a first intensified optical imaging sensor and to direct a second portion of the incident light to impinge on a second color optical imaging sensor;

receiving, by the camera system controller, first intensified optical imaging sensor data from the first intensified optical imaging sensor under low illumination conditions;

receiving, by the camera system controller, second color optical imaging sensor data from the second color optical imaging sensor under high illumination conditions;
