Description
In order to display characters in colors on the display screen of a color display device, the device is required to include a character information storing means for storing character information on characters displayed on the display screen and color information storing means for storing color information on the display color and background color of the device characters. Thus, a display means can display a predetermined character on the display screen in a predetermined color, on the basis of the information stored in the character information storing means and color information storing means.
FIG. 6 is a flow chart showing the processing for storing character data in the character data storing part 21 to FIG. 4;
The clock signal from the clock generator 6 is also applied to the CRT control circuit 9. The CRT control circuit 9 reads out from the refresh memory 10 in a period when the microprocessor 3 does not access the refresh memory 10. The read-out data is converted by the parallel-serial converter 11 into a train of square pulses. The pulse train thus obtained is used as a video signal v which is applied to the CRT 1. The CRT 1 also receives a synchronizing signal s which is delivered from the CRT control circuit 9. Thus, when an instantaneous value of the video signal v takes a high level, a display dot on the display screen of the CRT which corresponds to the above instantenuous value, is made bright. The display screen of the CRT 1 is scanned in such a manner that the first (namely, uppermost) to last scanning lines are successively scanned and each scanning line is scanned from left to right, on the basis of the synchronizing signal s, to be able to use all display dots on the display screen of the CRT 1. Accordingly, the CRT control circuit 9 reads out data from the refresh memory 10 in such a manner that data to be displayed in the first row is successively read out in a direction from left to right and then data to be displayed in the second row is successively read out in a direction from left to right, and the read-out data is sent to the parallel-serial converter 11. The CRT control circuit 9 sends memory addresses to the refresh memory 10 so that data can be read out from the refresh memory 10 in the above-mentioned manner.
The refresh memories 101, 102 and 103 are simultaneously applied with a data read-out instruction which is sent out from the CRT control circuit 9 and includes a read pulse, a row address, a column address, and so on. Thus, the refresh memories 101, 102 and 103 deliver data at the same time. Data from the refresh memories 101, 102 and 103 are applied to the parallel-serial converters 111, 112 and 113, respectively, to be converted into a red video signal vR, a green video signal vG and a blue video signal vB, each of which has the form of a bit-serial pulse train. The video signal vR, vG and vB are applied to the CRT 1, to make bright or dark the red display dots, green display dots and blue display dots, respectively, thereby performing color display.
Next, explanation will be made on the editorial processing in colors which is the subject of the present invention. First, the contents of each of various information-storing parts or areas will be explained, with reference to FIGS. 4 and 5a through 5e. As explained previously and shown in FIG. 4, information as to the kind of each of the characters displayed on the display screen of the CRT 1 such as the first and second characters, is stored in the character information storing part 21, and color information with respect to each of these characters is stored in the color information storing part 22. The information as to the kind of the characters and the color information thereof are stored in continuous storage areas of the storing part 21 and continuous storage areas of the storing parts 22, respectively, in accordance with the character display positions on the display screen of the CRT 1. Like a character code, color information of one character is stored in a one-byte storage area. The color information includes information with regard to the display color (hereinafter referred to as "front color") of a character and information with regard to the background color (hereinafter referred to as "back color") of the character. In FIG. 4, reference symbols RF, GF AND BF at the seventh, sixth and fifth bits of one byte correspond to a red front color, a green front color and a blue front color, respectively, and reference symbols RB, GB and BG at the third, second and first bits correspond to a red back color, a green back color and a blue back color, respectively.
FIG. 10 is a flow chart showing the operation of the color information processing means CTLE for processing the color information stored in the color information storing portion 22. According to the means CTLE, the display color of each of the characters included in that portion of the color information storing portion which corresponds to the colored editorial area set by the means CRAS, is set to the color specified by the color setting means ECRS. In more detail, bits which correspond to the above characters and indicate the same color as specified by the means ECRS, are set to a level "1". As mentioned previously, the symbols RF, GF and BF in FIG. 4 designate the red front color indicating bit, green front color indicating bit and blue front color indicating bit, respectively, and the symbols RB, GB and BB designate the red back color indicating bit, green back color indicating bit and blue back color indicating bit, respectively. Now, the flow chart of FIG. 10 will be explained below in detail. In steps 1001 and 1002, the editorial area start address and editorial area end address in the color information storing part 22 are calculated on the basis of the start and end positions of the colored editorial area by the means CRAS, and are stored in the RAM 2 at predetermined addresses thereof. Next, in step 1003, a pointer for indicating each address of the color information storing portion 22 is set at the start address calculated in step 1001. Further, it is indicated that the following processing is carried out at addresses specified by the pointer. In step 1004, the color information which has been stored in the RAM 2 in step 904 of FIG. 9, is read out, and it is judged which of the red front color, green front color and blue front color is indicated by the read-out color information. One of steps 1005, 1006 and 1007 is selected in accordance with the front color thus determined, and thus one of the bis "RF ", "GR " and "BR " at the address indicated by the pointer is set to the level "1". In step 1008, the color information which has been stored in the RAM 2 in step 908 of FIG. 9, is read out, and it is judged which of the red back color, green back color and blue back color is indicated by the read-out color information. One of steps 1009, 1010 and 1011 is selected in accordance with the back color thus determined, and thus one of the bits "RB ", "GB " and "BB " at the address indicated by the pointer is set to the level "1". In step 1012, the address indicated by the pointer is advanced by one, to perform the above operation at the next address. It is judged in step 1013 whether the advanced address is greater than the end address calculated in step 1002, or not. When the advanced address is greater than the end address, the color updating processing terminates. When the advanced address is not greater than the end address, the processing in step 1004 is carried out.
FIG. 13 is a flow chart showing the operation of the character pattern preparing means CPG. Referring to FIG. 13, red character pattern, green character pattern and blue character pattern which will be transferred to the refresh memories 101, 102 and 103, respectively, are prepared in the storage areas R, G and B of FIGS. 5a, 5b and 5c, by means of red character pattern preparing means RPGN, green character pattern preparing means GPGN and blue character pattern preparing means BPGN. The operation of each of the means RPGN, GPGN and BPGN will be explained below in detail, with reference to FIGS. 14, 15 and 16. FIG. 14 is a flow chart showing the operation of the red character pattern preparing means RPGN. Referring to FIG. 14, the zero clear is performed for the storage area R (step 1401). Then, it is judged in step 1402 whether the bit RF in the color information storing part 22 has a level "1" or not. When the bit RF has the level "1", the character font information which has been stored in the storage area P in step 1203 of FIG. 12, is transferred to the storage area R (step 1403). Then, it is judged in step 1404 whether the bit RB in the color information storing part 22 has the level "1" or not. When the bit RB has the level "1", the logical sum of the character font information which has been stored in the storage area P in step 1204 of FIG. 12, and the character font information stored in the storage area R, is produced and stored in the storage area R (step 1405).
FIG. 15 is a flow chart showing the operation of the green character pattern preparing means GPGN. Referring to FIG. 14, the zero clear is performed for the storage area G (step 1501). Then, it is judged in step 1505 whether the bit GF in the color information storing part 22 has the level "1" or not. When the GF has the level "1", the character font information which has been stored in the storage area P in step 1203 of FIG. 12, is transferred to the storage area G (area 1503). Then, it is judged in step 1504 whether the bit GB has the level "1" or not. When the bit GB has the level "1", the logical sum of the character font information which has been stored in the storage area P in step 1204 of FIG. 12, and the character font information stored in the storage area G, is produced and stored in the storage area G (step 1505).
FIG. 16 is a flow chart showing the operation of the blue character pattern preparing means BPGN. Referring to FIG. 16, the zero clear is performed for the storage area B (step 1601). Then, it is judged in step 1602 whether the bit BF in the color information storing portion 22 has the level "1" or not. When the bit BF has the level "1", the character font information which has been stored in the storage area P in step 1203 of FIG. 12, is transferred to the storage area B (step 1603). Then, it is judged in step 1604 whether the bit BB has the level "1" or not.
