Abstract

The proposed production system comprises at least a camera producing a raw digital signal and a processing circuit for generating a processed video signal from the raw digital signal. In a control area, at least a camera control interface is able to set at least a parameter in the processing circuit. The processing circuit is located in the control area.

An image capturing system for such a production system is also presented.

Claims

1. A production system comprising:

at least a camera producing a raw digital signal;

a processing circuit for generating a processed video signal from the raw digital signal;

a control area with at least a camera control interface for setting at least a parameter in the processing circuit;

wherein the processing circuit is located in the control area.

2. A production system according to claim 1, wherein the camera and the control area are linked via a communication channel with noticeable latency.

3. Production system according to claim 2, wherein the communication channel is liable to a delay of 100 ms or more.

4. Production system according to claim 1, wherein the camera has an iris and means for transmitting information indicative of the iris aperture as metadata to the raw digital signal.

5. Control area for a production system comprising:

means for receiving a raw digital signal generated by a camera;

a processing circuit for generating a processed video signal from the raw digital signal;

a camera control interface for setting at least a parameter in the processing circuit.

6. Control area according to claim 5, with means for receiving information indicative of the aperture of an iris of the camera as metadata to the raw digital signal.

7. Control area according to claim 6, wherein the camera control interface comprises camera controls generating at least a luminance information and means for setting a gain parameter in the processing circuit based on the luminance information and on the information indicative of the aperture of the iris of the camera.

8. Control area according to claim 5, with means for receiving a processed signal generated by a further camera.

9. Image capturing system for a production system comprising:

a camera producing a raw digital signal;

means for sending the raw digital signal on a communication channel.

10. Production system comprising:

at least a camera producing a raw signal and

a processing circuit for generating a processed video signal from the raw signal;

camera controls for controlling parameters in the processing circuit,

wherein the camera and the processing circuit are linked via a remote communication channel.
