Abstract

See full text

A system is provided for capturing a key signal within video frames that includes a camera that captures a sequence of media content of a live scene that includes an electronic display having a higher frame rate than an output frame rate of the camera, and a key signal processor that convert all frames in the sequence of media content to the output frame rate of the camera, analyzes a sequence of frames to determine the key signal based on the electronic display outputting a sequence of frames including media content and at least one key frame included in the sequence, and combine remaining frames of the sequence of frames to create a live output signal. Moreover, the key signal processor determines, for each pixel in the frames, whether the pixel has a set chromaticity, and generates a key mask for each pixel in each frame.
