Digital chromakey apparatus |
摘要 |
The digital chromakey system filters out a color signal from a first digital color-television signal and produces a chromakey signal which is combined with the first digital color-television signal to cancel out the color portion. The chromakey signal is also combined with a second color-television signal so that the second color television signal can be inserted into the first color-television signal whose color portion was cancelled.
