Color grading table storage part 121 has the color grading table, preserves the corresponding relation of the color number of the pixel value of font data and display device output.

Fig. 5 represents the color grading table 503 in the example of this example.Color grading table 503 pair background parts, the 1st body part, the 2nd body part and marginal portion have the column of preserving pixel value and color number.Deburring color portion 130 and not deburring color portion 131 write down pixel value and color number and carry out reference in color grading table 503.

Data bitmap storage part 122 has data bitmap table 504, with the corresponding number of saving colors of pixel of font data.Data bitmap table 504 is preserved the character of a character that has generated or the data bitmap of figure.

As shown in Figure 6, data bitmap table 504 is made of vertical 16 pixels, horizontal 16 pixels, has the column with the corresponding number of saving colors of pixel of font data.

When what generate indication impact damper 102 will deny deburring when being masked as 1 (deburring is arranged), and deburring color portion 130 is from denying that deburring detection unit 103 sends the indication of handling, and deburring color portion 130 generates the data bitmap of band deburrings, and is recorded in the data bitmap table 504.

When what generate indication impact damper 102 will deny deburring when being masked as 0 (no deburring), and from denying that deburring detection unit 103 sends the indication of handling, not deburring color portion 131 generates the data bitmap of band deburrings, and is recorded in the data bitmap table 504.

＜data bitmap generates to be handled 〉

Below, with reference to the action of the data bitmap generating apparatus of this example of flowchart text.

Acceptance division 7 receives the generation indication that indicating device 300 sends through artificial satellite or communication line.Generating indication acceptance division 101 accepts the generation indication of input part 6 receptions and is kept to generate in the indication impact damper 102 (step 81).

Show Color obtaining section 104 is taken out the color number of background parts, the 1st body part, the 2nd body part and marginal portion from generate indication impact damper 102, and each color that will take out number is notified to deburring color portion 130 and not deburring color portion 131 (steps 82).

Character code obtaining section 105 is taken out character code from generate indication impact damper 102, and the character code notice font data that takes out is read portion 111.Font data is read a character corresponding with the character code of character code obtaining section 105 notices read by portion 111 from font data storage part 110 font data, and is notified to deburring color portion 130 and not deburring color portion 131 (steps 83).

To deny deburring detection unit 103 take out from generate indication impact damper 102 will deny the deburring sign, indicate when wanting deburring deburring color portion 130 is handled, and when not wanting deburring, indicates not deburring color portion 131 is handled (step 84).

Deburring color portion 130 generates the data bitmap of band deburring, and is recorded in the data bitmap table (step 85).

Not deburring color portion 131 generates not the data bitmap with deburring, and is recorded in the data bitmap table (step 86).

Fig. 8 is the process flow diagram of the detailed process content of expression deburring color portion 130 above-mentioned steps 85 of carrying out.。

Write down 0,1,2,3 respectively in the pixel value hurdle of deburring color portion 130 background parts, the 1st body part, the 2nd body part and marginal portion, in the good hurdle of color, write down the color number (step 11) of the background colour of Show Color obtaining section 104 notice, the 1st body colour, the 2nd body colour and edge look respectively at color grading table 503.

Deburring color portion 130 is with reference to color grading table 503, a pixel the font data of reading portion 111 notice from font data is obtained the color corresponding with pixel value number (step 12), and this color number is recorded in (step 13) in the corresponding hurdle of data bitmap table 504.This processing is carried out (step 14) to all pixels of this font data.

Above-mentioned Fig. 5 represents when background colour is that 0 (white), the 1st body colour are that 255 (black), the 2nd body colour are 160 (dark brown), the result that execution in step 11 obtained when the edge look was 64 (redness), the content of color grading table 503.

Above-mentioned Fig. 6 represent to Fig. 4 font data 502, the result who obtains to step 14 according to the content execution in step 12 of the color grading table 503 of Fig. 5, be the content of data bitmap table 504.Record carries out deburring as color number 64 (redness) of edge look in the pixel of marginal portion.

Fig. 9 is the process flow diagram of the detailed process content of expression deburring color portion 131 above-mentioned steps 86 of carrying out.

Write down 0,1,2 respectively in the pixel value hurdle of deburring color portion 131 background parts, the 1st body part, the 2nd body part, in the color hurdle, write down the color number (step 21) of the background colour of Show Color obtaining section 104 notices, the 1st body colour, the 2nd body colour respectively at color grading table 503.In the pixel value hurdle of same edge part, write down 3, the color number (step 22) of the background colour that record Show Color obtaining section 104 is notified in color number is blocked.

Deburring color portion 131 is with reference to color grading table 503, a pixel the font data of reading portion 111 notice from font data is obtained the color corresponding with pixel value number (step 23), and this color number is recorded in the corresponding hurdle of data bitmap table 504 (step 24).This processing is carried out (step 25) to all pixels of this font data.

Figure 10 represents when background colour is that 0 (white), the 1st body colour are that 255 (black), the 2nd body colour are 128 (grey), the result that execution in step 21 and 22 obtained when the edge look was 64 (redness), the content of color grading table 503.In the color hurdle of marginal portion, write down color number 0 (white) of look as a setting.

Figure 11 represent to Fig. 4 font data, the result who obtains to step 25 according to the content execution in step 23 of the color grading table 503 of Figure 10, be the content of data bitmap table 504.In the pixel of marginal portion, write down color number 0 (white) of look as a setting, do not carry out deburring.

As mentioned above, in the 1st example, the character of file deburring in advance and the font data of figure, when wanting deburring, read the font data of body part, marginal portion and background parts from memory storage, generate the data bitmap of character and figure, so, the calculation process at the edge of character and figure needn't be used for calculating one by one, the increase in processing time can be suppressed.In addition, when not wanting deburring, the marginal portion of the font data of above-mentioned memory device stores is replaced to background parts, the character that generation is made of body part, background parts and the data bitmap of figure, so, the not font data of deburring needn't be stored, the increase of font data memory capacity can be suppressed.

Therefore, can provide a kind of and generate the character, figure of band deburring apace and not with the device of the data bitmap of the character of deburring, figure with few memory capacity.

Have again, in above-mentioned example, by the marginal portion being replaced to the data bitmap that background parts goes to generate not deburring, but, equally, by body part is replaced to background parts, only can generate the data bitmap of null character (NUL) in the what is called of forming by the marginal portion.

Have again, also can represent to generate indication with other form.For example, also can make will deny that the deburring sign is corresponding with other value, represents the appointment of color with rgb value, represents character code with other code specifications.When carrying out the appointment of color with rgb value in generating indication, the record that generates the color in indication impact damper 102, color grading table 503, the data bitmap table 504 carries out with RGB entirely.
