Image forming apparatus and method
First Claim
1. An image forming apparatus for dealing with videotex codes consisting of a sequential arrangement of geometric codes representing individual image areas as respective geometric drawings and also characteristic codes representing attributes of said geometric drawings, said apparatus comprising:
- means for effecting transmission of said geometric codes and characteristic codes;
an order table for supervising the order of transmission of said geometric codes and characteristic codes;
a characteristic code table communicating with said order table and enabling selection of said characteristic codes; and
means for analyzing data in said tables and effecting changes therein.

Abstract
In changing or otherwise handling sequential videotex codes composed of geometric codes representing individual image areas as respective geometric drawings and also characteristic codes representing attributes of the geometric drawings, the order of transmission of the geometric codes and characteristic codes is supervised on an order table and a characteristic code table is provided for supervising the characteristic codes, with correction or rearranging of the videotex code data being effected on these tables. In the case where the videotex codes are to represent an input color image, a histogram of the frequencies of occurrence of all colors represented by color data for each input color image is produced and a predetermined relatively small number n of colors having the highest frequencies of occurrence, either in the histogram as a whole, or in divisions of the histogram, are selected and each image area has assigned thereto color data representing the one of the n selected colors closest to the actual color of the image area in question.

11. A method of changing videotex codes consisting of a sequential arrangement of codes including geomoetric codes representing individual image areas as respective geometric drawings and also corresponding characteristic codes representing attributes of said geometric drawings, said method comprising the steps of:
-
temporarily storing said videotex codes in said sequential arrangement; analyzing the temporarily stored codes as geometric and characteristic codes, respectively, and entering said geometric codes and pointers identifying corresponding characteristic codes in an order table according to the order of said geometric codes in said sequential arrangement; entering said characteristic codes in a characteristic code table according to the order of said pointers identifying the characteristic codes; and changing said codes on said tables. - View Dependent Claims (12)
