Camera Control Unit Procedure

 

The Camera control unit is an equipment which is operated with remote controls. Remote controls are used for the treatment of the images of cameras. With the succeeding steps, the remote controls will adjust each image of cameras. As a result, the images should have the same appearance on television. There are six steps to follow: the adjustment of the black, the white, the flare, the gamma, the detail and the saving procedure.

 

To begin, the Camera control unit requires some materials. Therefore, one Camera control unit have four remote controls. Each of them is for one camera. Indeed, if there are twenty cameras, there will be five Camera control units. The other materials needed are a monitor, a scope and, of course, cameras.

 

The first step is the adjustment of the black. This is to block a certain amount of light to penetrate the lens of the camera. On the remote control, the menu “Auto Black” is selected. The black will automatically balance. Then, in the menu “Paint 1”, the “Black” option is activated. After this step, the handle on the remote needs to be down to close the iris. In the monitor, the image should be dark, but not totally black. To obtain an intense black, turn the blue and the red buttons on the remote. As a result, the image should look black. The handle on the remote needs to be raise up to reactivate the iris.

The second step is the adjustment of the white. This will give the true colors for the cameras. With the remote control in “Paint 1”, the menu “White” is selected. Use the blue and the red buttons and adjust the white to 0,7V. This is how the camera will obtain the true colors for the television. The handle on the remote is to adjust the green. For this operation, rely on the top bars shown in the monitor.

The third step is the adjustment of the flare which is for the reflections. First, the “Waveform” button on the monitor is activated. Use the handle to add 1F stop. The “F stop” is the opening of the iris. The number will be shown one the remote. With the remote control in “Paint 1”, the “Flare” option is selected. Instead of using the handle for the green, it will be the green button that will replace it and for the blue and the red as well. To finish, with these three buttons, adjust the bottom middle bar to 0,3V. The flare is now done, the reflections are controlled.

The fourth step is the adjustment of the gamma or the contrast. In the menu “Paint 1” on the remote control, the option called “Gamma” is selected. Again, the blue and the red need to be at 0,42V with their respective buttons. To adjust the green, use the handle. To obtain 0,42V, rely on the big middle bar on the monitor. When it is all done, the contrast should be perfect.

The fifth step is the detail. The detail is crucial for the detail in the image. On the remote control in “Paint 2”, the button called “Detail Off” is deactivated. There is simply on button to adjust: “Level” or “Detail”. The level needs to be at 0,7V. For help, use the same top bars as the white on the monitor. The details will be, now, much clearer on television.

The last step is the safeguard to preserve all of the procedure. In the menu “Scene” on the remote control the option “Scene” is selected. There are numbers that will be shown. Select one number two times and the procedure will be save.

 

To conclude, these six steps are complex, but with a lot of practice, the procedure will become much easier. Your eyes will be used to the colors. As a result, it will be effortless to compose identical images. The black will block the unwanted light, the white will give the true colors to the cameras, the flare will adjust the reflections, the gamma will help with the contrast, the detail will give a better image and the safeguard procedure will preserve all the process. As a recommendation, starting early is a good option because it takes some time. If there are five cameras, this procedure must be done five times.

I already knew about this procedure, but now, because of you, it is so much more clear! thank you very much! Still, It is not clear what does this process is used for...

Amazing text ! CCU is a really complex and difficult procedure but you explained it really well! You gave definitions and why every step is important and needed. You also explained all the equipment and what to do if we have twenty (20) cameras. This is really helpful. What would have been even more helpful, is if you had introduce the monitor and the scope. What are they and why do we need those equipment ? Overall, I would definitely use your article to help me when I will do this procedure ! Great work, Marylou !
