METHOD OF ENCODING AND DECODING COLOR VIDEO PICTURE

摘要

A digital color image digitizing and communication process comprises the steps of dividing digital data representing the overall picture information for a image into sets of data representing shape and color information for blocks of the image with the color information including the major colors for the corresponding block and the variation in shades or hues of the colors within the block, separating each of the data sets into a first group of data representing the major colors constituting the block and a second group of data comprising the remaining data in the data sets, transmitting the first group of data and the second group of data to a decoder, processing the received first data group to display the encoded image in its major colors, and combining the first group of data with the selected data from the second data group and processing the combined data to display the encoded image with the variations in shades of the major colors.
