Next, the monochrome printer (4) stores red, green, and blue electronic figure memories (21), (22), and (23) corresponding to each dot on both sides of the color display (3) marked -I-. The logical sum condition of the bits at the same address specified by the figure information number stored in is taken, and if the result is "l", the corresponding dot is printed on the printing surface and the entire figure is printed. .

[rP1 problem to be solved by invention] Conventional color graphic table 71 Since monochrome 1 is used as it is in the printing machine, it is a figure formed by a 441 flattened pattern of multiple colors, and the brightness of adjacent colors in the pattern is the same or approximate I-. If the pattern is printed using a monochrome printer, the color boundaries cannot be distinguished, resulting in a disadvantage that clear monochrome printing cannot be achieved. In addition, in order to display and print clearly on both the color display and the monochrome printer, it is necessary to display the graphics twice, one for screen display and one for printing. It also had some drawbacks, such as abandoning the good color development of a color screen by crushing it, displaying figures with only borders or fine line patterns on the screen, and printing in monochrome.

The present invention has been made to solve the above-mentioned problems, and even when monochrome printing is performed at the same time as a color display of a figure in which a pattern is formed by touching colors of the same or similar brightness, the color screen is It is an object of the present invention to obtain a color graphic display device that can display graphics with good color development and that can clearly distinguish the boundaries of patterns and perform monochrome printing.

Monochrome graphic information is stored based on this control result, and monochrome printing can be performed based on this monochrome graphic information. Graphics in which colors of the same or similar brightness touch to form a pattern can be displayed as color graphics. Even if monochrome printing is performed at the same time, graphics can be displayed with good color development on a color screen, and the boundaries of the pattern can be clearly distinguished during monochrome printing.

Next, the operation of the color graphic display device according to the present embodiment will be explained, and the explanation of the same or equivalent portions as the operation of the conventional device will be omitted. First, a reversal command (65) is input to the figure generation processor (1) and the first
This mode displays only the outline of the figure (outline mode). In this outline mode, the color command page 81) and the fill command (62) are executed by the figure generation processor (
1), the color designation control unit (11) and filling control unit (12) of the graphic generation processor (1) generate graphic information in the same way as in the conventional device, and are specified by the graphic information. Colors and regions are stored in the color frame memory (2) (divide the specified color into three primary colors and store them in the color frame memories (21), (22), (23) of red, green, and blue corresponding to the three primary colors). do.

In addition to the outputs of the color designation control section (11) and the filling control section (12), inversion information of the filling inversion Φ non-inversion control section (13) is input to the monochrome figure memory (51). A NAND condition is applied to the bits at the same address as the graphic information stored in the graphic memory (2), and as a result, the corresponding bits of the monochrome graphic memory (51) are Graphic processing is performed using cents of "0" or "1". Through this graphic processing, the first graphic stored in the monochrome graphic memory (51) becomes a hollow graphic in which only the boundary is drawn.

Next, the figure generation processor (1) is given a non-reversal command (
6B) is input, the mode becomes a mode (filling mode) in which the second figure (shown in FIG. 2) is displayed half-filled. In this fill mode, the color command page 63) and the fill command (64) are distributed to the shape generation processor (1).
When input, this graphic generation processor (1) performs a logical sum condition on the bits at each address that is the same as the graphic information input to the color circumference memory (2), and as a result, the monochrome graphic memory (51) Each corresponding bit of “o”
Alternatively, set it to °゛l゛ and perform graphic processing. Through this graphic processing, the second graphic stored in the monochrome graphic memory (51) becomes a graphic in which all the corresponding parts are filled out.

When a print instruction is given, the t51 and second figures generated in each of the outline and fill modes are stored in the figure information stored in the monochrome figure memory (51).
Print a dot at a specific position on the monochrome printer (4) corresponding to the 1" bit.

Therefore, the printed figure is a hollow figure with only a frame drawn (
, the first figure) and the filled figure (the second figure),
The boundaries become clear.

Note that the criteria for selecting each of the outline and filling modes is appropriately selected based on the brightness difference between adjacent colors among the various colors forming the pattern of the target figure. That is, the outline mode is set only when the brightness difference between the adjacent colors exceeds the viewer's permissible discrimination range, and the fill mode is set when it is within the permissible range.

In the above embodiment, a color graphic display device is provided with a monochrome graphic memory (51) and is equipped with means for reversing processing. It may be changed to memory, or figures suitable for monochrome display can be generated using the same command sequence (program) as in the case of color.

[Effects of the Invention] As explained below, the present invention includes a figure generation processor having a one-color specification control section, a fill control section, and a fill inversion/non-inversion control section, and a figure generation processor that generates color figure information based on the output of the figure generation processor. A figure memory having a color circumference memory for storing and a monochrome figure memory for storing monochrome figure information, and a figure is displayed on a color display based on the output of the color circumference memory, and 1- Motsuchrome figures are displayed. Since we have adopted a configuration in which figures are printed using a monochrome printer based on the output of the memory, it is possible to invert or non-invert the area specified by the color command and fill command in response to an externally input invert or non-invert command. Control is performed, monochrome graphic information is stored based on this control result, and monochrome printing can be performed based on this monochrome graphic information, and a pattern in which colors of the same or similar brightness touch each other to form a pattern is printed as a color graphic. Even if monochrome printing is performed at the same time as display, it is possible to display graphics with good color development on a color screen, and the monochrome printing can be performed with clearly distinguishable boundaries between patterns.
