Abstract
Provided is a gray scale shape data encoder in shape data coding devices, including: video signal generating device for receiving a video signal, extracting and outputting shape data; transparency data extracting device for receiving the shape data from the shape data extracting device, extracting and outputting transparency data; boundary block merging device for receiving the transparency data output from the transparency data extracting device, performing a boundary block merging, and outputting the merged signal; transparency data coding device for receiving the transparency data merged in the boundary block merging device, coding and outputting them; supporting device for receiving the shape data from the shape data extracting device and extracting binary shape data; binary shape data coding device for receiving binary shape data from the supporting device, coding and outputting them; and binary shape data decoding device for receiving the coded binary shape data from the binary shape data decoding device, re-decoding them and outputting the reproduced binary shape data.
