Abstract

An image intensification camera system (C) for gathering image data includes an image intensifier (310) for amplifying received light (312). A relay optic assembly (316) is coupled between the image intensifier (310) and a digital image sensor (318), such as a CMOS or CCD device. Digital logic (322) is used to process or output an image or related data (334).

Claims

1. An image intensification camera system for gathering image data, the system comprising:

an image intensifier means for amplifying received light;

a light transmitting assembly between the image intensifier and a digital image sensor to communicate the amplified received light from the image intensifier;

a digital image sensor to receive and electronically transform the amplified received light from the image intensifier; and

, digital logic circuitry electronically connected to at least the digital image sensor to process an image or related data.

2. The invention of claim [claim Reference] wherein the digital logic circuitry adjusts one or more operating characteristics of the digital image sensor selected from the group consisting of:

digital frame rate;

contrast and brightness;

digital image enhancement;

bad sensor pixel detection and correction; and

camera synchronization.

3. The invention of claim [claim Reference] wherein the digital logic circuitry adjusts one or more operating characteristics of the image intensifier selected from the group consisting of:

image intensifier gain;

gating; and

synchronization.

4. The invention of claim [claim Reference] wherein the digital image sensor is a charge coupled device (CCD).

5. The invention of claim [claim Reference] wherein the digital image sensor is a CMOS device.

6. The invention of claim [claim Reference] wherein the light transmitting assembly is a relay optic.

7. The invention of claim [claim Reference] wherein the light transmitting assembly is a fiber optic bond.
