tables listing color values in order of contrast on pages 6
and 7 of the specification.
Specific embodiments are shown in block diagram form in
Figs. 2 and 3. Block 30 represents a keyboard or other memory
device to supply character information signals on line 33 and
synchronizing signal information on line 31 to a picture
memory 34. In the case of Fig. 2, the picture memory is
preceded by a histogram former 32, which detects color
indicator signals. A picture memory 34 stores one or more
pages of information or a bit map. The stored information is
then transmitted to a charac- ter generator 36, which receives
information about each character or bit, including a color
code (page 10, lines 9-23). These com- ponents receive a
synchronizing signal from control unit 42 so that the
character code information can be consecutively read and
converted into pixels having a three bit color indication
(page 10, lines 32-34). The claimed apparatus can also detect
specific character categories and/or specific text configura-
tions in the output signal of the character generator by means
of a detector in the character generator which is set by
