Image　files　with　RAW　format　are　simple,　no　header　and　no　color　palette,　and　each　byte　directly　stands　for　a　pixel　intensity.　So　many　researchers　who　study　image　compression　or　image　processing　algorithms　constantly　use　RAW　format　file.　But　it　is　difficult　to　display　intuitively　the　qualities　of　the　images　with　RAW　format　after　image　compression　or　image　processing.　In　this　paper　we　convert　image　files　with　RAW　format　to　BMP　format　in　a　fractal　Video　decompression　system　and　display　the　decompressed　image　sequence　as　a　section　of　Video.　Furthermore,　we　use　multi-thread　technology　to　implement　decompression　and　display　synchronously　so　that　end　users　of　the　fractal　Video　decompression　system　don＇t　need　to　wait　a　long　time　to　view　the　decompressed　Video.
