Abstract

A modular camera system includes a camera body having a housing, which has a rearward facing end, a forward facing end opposite the rearward facing end, and a plurality of mounting surfaces extending between the rearward facing end and the forward facing end. A photosensor and lens mount are mounted on the forward facing end of the camera body, the lens mount for removably attaching a lens assembly configured to direct photons from an area outside the camera body to the photosensor. A processor within the camera body converts a signal from the photosensor to a video signal. A display assembly removably attachable to the rearward facing end of the camera body includes a display screen configured to display the video signal received from the processor in human viewable form. Each of the plurality of mounting surfaces includes one or more fastener elements for removably and interchangeably attaching an accessory module.

Claims

1. A modular camera system, comprising:

a camera body having a first housing, the first housing having a rearward facing end, a forward facing end opposite the rearward facing end, and a plurality of mounting surfaces extending between the rearward facing end and the forward facing end;

a photosensor mounted on the forward facing end of the camera body;

a lens mount attached to the forward facing end of the camera body for removably attaching a lens assembly configured to direct photons from an area outside the camera body to the photosensor;

a processor within the camera body operably coupled to the photosensor and configured to convert a signal received from the photosensor to a video signal;

a display assembly configured to be removably attached to the rearward facing end of the camera body, the display assembly including a display screen configured to display the video signal received from the processor in human viewable form; and

each of the plurality of mounting surfaces includes one or more fastener elements for removably and interchangeably attaching an accessory module.

2. The modular camera system of claim 1, wherein at least one of said mounting surfaces includes an electrical connector configured to provide an electrical coupling between the camera body and an attached accessory module.

3. The modular camera system of claim 1, wherein the photosensor is sensitive to radiation in the short wave infrared (SWIR) region.

4. The modular camera system of claim 1, wherein the processor includes a digital signal processor for converting the signal received from the photosensor to a digital video signal.

5. The modular camera system of claim 1, further comprising:

said display assembly removably attached to the camera body;

a video connector on the rearward facing end of the camera body mating with an aligned video connector on the display assembly.

6. The modular camera system of claim 1, further comprising a plurality of lens assemblies interchangeably attachable to the lens mount.

7. The modular camera system of claim 1, wherein each of the mounting surfaces includes a pair of opposing axially extending channels, each axially extending channel configured to receive a complementary slide rail on an attached accessory device.

8. The modular camera system of claim 1, further comprising:

a keypad module including a second housing configured to be removably attached to a selected one of said mounting surfaces and a plurality of keys, the keypad module operatively coupled to the camera body for controlling operation of the modular camera system.

9. The modular camera system of claim 8, further comprising:

a laser light source attached to the keypad module, the keypad module including one or more keys for controlling operation of the laser light source.

10. The modular camera system of claim 1, further comprising:

a laser module including a second housing configured to be removably attached to a selected one of said mounting surfaces and one or more laser light sources mounted within the second housing, wherein the laser module is configured to operate as one or more of a laser designator, laser pointer, and a laser illuminator.

11. The modular camera system of claim 10, wherein the photosensor is sensitive to a wavelength corresponding to a wavelength of at least one of said one or more laser light sources.

12. The modular camera system of claim 1, further comprising:

a mounting shoe module having a second housing configured to be removably attached to a selected one of the mounting surfaces; and

a mounting shoe disposed on the second housing.

13. The modular camera system of claim 12, further comprising:

a first set of electrical contacts on the mounting shoe module contacting a second set of electrical contacts on at least one of said mounting surfaces when the mounting module is attached to said at least one of said mounting surfaces; and

a third set of electrical contacts on the mounting shoe electrically coupled to the first set of electrical contacts for electrically coupling the first set of electrical contacts to a power supply.

14. The modular camera system of claim 13, further comprising the power supply module, said power supply having a third housing and one or more electric batteries received within the third housing, the power supply module including a receptacle for removably receiving the mounting shoe and a fourth set of electrical contacts within said receptacle and electrically coupled to said one or more electric batteries.

15. The modular camera system of claim 12, wherein the mounting shoe is a dovetail mounting shoe.

16. The modular camera system of claim 12, further comprising:
