    • G09G5/24—Generation of individual character patterns

Definitions

  • FIG. 3 The character depicted in FIG. 3, in the graphical form thus formed, is first displayed within a 16 x 12 bit matrix.
  • This 16 x 12 bit matrix with the columns P1 to P16 and the rows Z1 to Z12 is now split into two matrices, FIGS. 4 and 5.
  • 4 contains the odd number 3
  • FIG. 5 the even-numbered columns of FIG. 3.
  • the characters are stored in two character generators ZG1 and ZG2 in the inventive mixing circuit arrangement (FIG. 6).
  • the character generator ZG1 which may have a memory content of 2K x 8 bits, for example, contains an 8 x 12 pixel matrix, corresponding to FIG.
