Abstract

PURPOSE: To shorten an access time for retrieval, and also to improve economy with improved efficiency of coding and simplified filing operation, by coding a color picture by dividing it into a color region code, boundary code, etc.
CONSTITUTION: Pictures used for information services have a relatively-small number of kinds and many of them have relative-wide regions where the same color continues, which are advantageous to coding. For example, a picture with background 101 colored in red, triangle 102 in green, and rectangle 103 in bule is coded as shown by (a) to (c). Namely, (a) shows a coding format example (color region code) for the region where the same color continues, (b) shows a coding format example (boundary code) for the part where white and black lines expressing a boundary, line pattern and character are residing or different-color regions adjoin, and (c) showns a command code example indicating the start and end of coding data.
