Film mode progressive scan conversion

摘要

The television system with progressively scanned display has an input line for transmitting a current video field of data originally produced on film. A first memory stores data for a most recent previous video field, and a second memory stores data for a second most previous video field. A processor compares the most recent previous field with the current field and the second most previous field such that a motion signal is selected by comparing motion signals between the current field and the most recent previous field, and between the most recent previous field and the second most previous field, where the minimum motion signal is used to generate progressive frames of the data originally produced on film. A spatial light modulator displays the progressive frames of video data as an image. The processor is operable to set a minimum threshold for the minimum motion signal to reduce noise effects.
