ABSTRACT:
A method and apparatus for providing accurate, real-time monitoring of image compression processing. Video data is compressed by a microprocessor running a video compression algorithm. A product of this compression process is a decompressed (i.e., companded) image to be used in the compression of the next video image. This companded image is also used by the video capture system for display for real-time monitoring of video compression processing. In a preferred embodiment, every video frame that is compressed, is also displayed in real-time on a display monitor.
