GOM Cam

What is the “Chroma-key” function for webcams?

The chroma-key function enables you to combine a desired color or image in a specific color area.

An easy-to-understand example is the weather information screen displayed during TV weather forecast.

In the TV weather forecast, we see a weather broadcaster standing in front of a large weather screen. In actuality, the broadcaster is standing in front of a blue or a green screen, and the weather information screen is combined in the screen area behind the broadcaster during the editing work.

For more details about the chroma-key function, refer to the following link:

You can use the Chroma-key function of GOM Cam with the following procedure:

4. Select 'Background setting', and set the color or image to be inserted in the chromakey area.
