    摘要: A movie set can include light sources each producing a light corresponding to a light channel, at least one high-frame rate camera, and a controller connected to the light sources and camera to synchronize the camera and light sources. The number of light channels can be proportional to the frame rate. For example, if the filming frame rate is 120 frames per second (fps) and the playback frame rate is 24 fps, then 5 light channels can be used. In this example, for every one playback frame, 5 frames were filmed by the high frame rate camera. The controller modulates the light channels such that each of the 5 frames has different lighting characteristics. In post-production, contributions from each of the light channels can be included or excluded from the final frame. An optical flow algorithm can be used to stitch together frames with different dynamic light characteristics.
