Abstract

Предоставлен способ создания видеопотока. Способ включает в себя прием в конечное запоминающее устройство первого и второго видеопотоков. Первый видеопоток отличается от второго видеопотока. Каждый видеопоток включает в себя последовательности из видеоизображений, каждое из которых имеет множество пикселей. Каждый пиксель имеет один компонент яркости и два компонента цветности. Способ включает в себя этап, на котором преобразовывают с использованием вычислительного процессора компонент яркости первого пикселя в первом изображении первого видеопотока в компонент непрозрачности. Способ также включает в себя этап, на котором объединяют, используя вычислительный процессор, компонент непрозрачности первого пикселя и цветовые компоненты второго пикселя в исходящий пиксель. Способ, в конечном счете, включает в себя этап, на котором выводят выходной видеопоток, содержащий исходящий пиксель.
