Abstract

A CCD camera system has reconfigurable hardware and is controlled by a computer having reconfigurable software. The computer can receive and transmit signals between the system and a ground station. The hardware and software are reconfigurable based on signals from the ground station.

Claims

1. A CCD camera system for use in space, said system being in signal communication with a ground station, said system comprising a CCD having an input and output, said input of said CCD being connected to at least one of reconfigurable hardware, reconfigurable software and field programmable gate arrays, said camera system being controlled by a computer, said computer controlling said CCD input and said CCD output, said computer having means to receive and transmit signals between said system and said ground station, said system being reconfigurable based on signals from said ground station.

2. A camera system as claimed in claim 1 wherein the computer has reconfigurable memory and reconfigurable software for operation thereof, said software being reconfigurable based on signals from said ground station.

3. A camera system as claimed in claim 1 wherein the system has reconfigurable hardware, the reconfigurable hardware comprising a reconfigurable clock generator.

4. A camera system as claimed in any one of claims 1, 2 or 3 wherein the system has reconfigurable hardware comprising programmable level shifters.

5. A camera system as claimed in any one of claims 1, 2 or 3 wherein an analog signal processor is connected between said CCD output and said computer to convert analog data from said output to digital data.

6. A camera system as claimed in any one of claims 1, 2 or 3 wherein the computer has a computer data bus connected to said reconfigurable clock generator, said reconfigurable clock generator being connected between said memory and said programmable level shifters, said clock generator also being connected to said analog signal processor, said programmable level shifters being connected to said camera input.

7. A camera system as claimed in any one of claims 1, 2 or 3 wherein the system has any two of reconfigurable hardware, reconfigurable software and field programmable gate arrays.

8. A camera system as claimed in any one of claims 1, 2 or 3 wherein the reconfigurable hardware has reconfigurable memory.

9. A camera system as claimed in any one of claims 1, 2 or 3 wherein the system has all three of reconfigurable hardware, reconfigurable software and field programmable gate arrays.

10. A method of reconfiguring a CCD camera system in space using signals from a ground station, said system having a CCD with an input and an output, said input being connected to at least one of reconfigurable hardware, reconfigurable software and field programmable gate arrays, said camera system being controlled by a computer, said computer having means to receive and transmit signals between said system and said ground station, said method comprising sending a signal from said ground station to said computer to reconfigure said system.

11. A method as claimed in claim 10 wherein said computer has reconfigurable memory and reconfigurable software, said method including the step of operating said computer using said reconfigurable software.

12. A method of operating a camera system as claimed in claim 10 wherein said system has a full frame CCD, said method including the step of controlling said full frame CCD as a frame transfer CCD.
