Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document processing apparatus with an enlargement / smoothing function, and in particular, an image of an enlarged character which has been enlarged by a magnifying command for a character or symbol is temporarily displayed on the display, The present invention relates to a device that enables key input during smoothing processing to facilitate key input.

[0002]

2. Description of the Related Art Conventionally, in a word processor equipped with a display, an image of a basic size of a character such as a character or a symbol is stored as a dot pattern (image data) composed of a dot matrix, and an input code is input. The dot pattern of the character corresponding to the data can be displayed on the display or printed on the printing paper in the normal character size or in the enlarged character size.

By the way, when displaying or printing a magnified character in which the character is magnified, simply enlarging the dot pattern of the character will roughen the contour of the character and impair the aesthetic appearance of the character. Various character enlargement techniques have been proposed in which, in addition to the processing, smoothing processing for smoothing the contour is simultaneously performed.

For example, in Japanese Patent Laid-Open No. 61-208082, a dot pattern corresponding to 5 dot lines is read out from the supplied character pattern, and the rightmost dot row data of this dot pattern is converted into an address. Based on the partial pattern including the conditions of interpolation and deletion, which are converted in address by the means and stored in advance in the partial pattern memory,
There is described a character pattern generation device in which a dot pattern for one dot line at the center of the dot pattern is enlarged, and thereafter, similar enlargement / smoothing processing is similarly performed for each dot line.

Further, in Japanese Patent Publication No. 63-10433, contour data is obtained by tracing contours by using a mask method on a region including a character pattern consisting of a dot matrix, and edges are sequentially obtained from the contour data. If the inclination between the adjacent edges is horizontal or vertical, these straight-line dots are simply enlarged, while if they are inclined, enlargement processing based on an arithmetic expression is performed to perform edge-to-edge interpolation. The character pattern enlarging method is described.

[0006]

As described above, in the character pattern generator disclosed in JP-A-61-28082 and the character pattern enlargement system disclosed in JP-B-63-10433, enlargement is instructed. With respect to characters and symbols, the dot pattern is enlarged for each dot line and smoothing is continuously performed, or enlargement and edge-to-edge interpolation are performed continuously based on the detected inclination between adjacent edges. The character corresponding to the character code input by key operation is not displayed until all of these processes are completed. Therefore, especially when instructing enlargement of multiple characters, it corresponds to the character code input by key operation for a long period from when instructing enlargement of these multiple characters until the image creation of the smoothed enlarged characters is completed. There is a problem that the display response speed of the displayed character becomes very slow and the operator is frustrated, and the efficiency of document creation decreases in proportion to the lengthening of the processing time.

It is an object of the present invention to provide a document processing apparatus with an enlargement / smoothing function which enables key input during smoothing processing executed in response to an enlargement instruction and enables key input to be performed quickly and smoothly. It is in.

Further, the image data of the enlarged character created by the enlargement processing means is smoothed by the smoothing processing means, and the image data output to the video RAM by the output control means is the image data smoothed by the smoothing processing means. Can be rewritten. On the other hand, whether or not there is an input from the input means is determined by the input determination means. When the input determination means determines that there is an input, the smoothing processing by the smoothing processing means is interrupted by the interruption command means.

As described above, the image of the enlarged character of each input character is output to the video RAM and is temporarily displayed on the display. While the image data of the enlarged character is smoothed, the processed image data is processed. When sequentially displaying on the display, when a key input is made, the smoothing process is interrupted and the key input is prioritized, so that the key input according to the key operation can be performed quickly and smoothly. As a result, the display response speed of the input character becomes very fast, and the operator's irritation can be eliminated, and the image of the enlarged character can be confirmed although smoothing processing has not been performed, and the processing efficiency of the document creation processing is greatly improved.

Display position data indicating the display position of the upper left corner of the image on the display, that is, the position (coordinates) of the upper left corner of the storage position in the video RAM 14, and the flag data of the completion flag KF for instructing the completion of the smoothing process are respectively stored. ..

Next, a character display control routine executed by the control unit C of the word processor 1 will be described with reference to the flowchart of FIG. Here, the main routine of the character display control is executed in the foreground, while the smoothing processing control is executed in the background for the main routine.
Further, the scanning scan for determining the presence / absence of key input on the keyboard 10 is executed every minute time. In the figure, reference numeral Si (i = 30, 31, 32 ...
・ ・) Is each step.

When the edit key of the keyboard 10 is operated, this control is started, and the presence / absence of a key input is first repeated every minute time (S30: No). Then, when the character key is operated (S30 / S31: Ye
s), the dot pattern of the code data corresponding to the character key is read from the character generator ROM 20 and stored in the pattern memory 32 (S32), and the enlargement flag LF is not set (S33: No),
The dot pattern is written in the video RAM 14 (S36), and the process returns to S30. That is, at the same time when the dot pattern is written in the video RAM 14, the display data based on the dot pattern is output to the display 12 by the hardware and displayed at the cursor display position.

On the other hand, when the enlargement key is operated (S
30: Yes, S31: No, 37: Yes), the enlargement flag LF is set (S38), and the process returns to S30. Next, when the size key is operated to specify the character size (S30: Yes, S31 / S37: No, 3

Next, it is determined whether or not there is a key input (S57), when there is no key input (S57: No), the counter i is incremented by 1 (S53), and when the smoothing process does not end for the enlarged pattern (S54: No). ) And S55 and subsequent steps are repeated. On the other hand, while executing S53 to S57,
When the key input is performed, it is determined Yes in S57,
The flag TF is set (S58), this control is interrupted and the process returns to the main routine. Then, S30 and subsequent steps of the main routine are executed.

By the way, in the main routine, S30
When it is determined that there is no key input when the control is returned to (S30: No), the smoothing process is executed again. Then, when the smoothing process for one enlargement pattern is completed (S54: Yes), the completion flag KF for the enlargement character which is pointed by the pointer P and has completed the smoothing process is set (S59). Next, when the next enlarged character information is stored in the information memory 35 (S60: Yes), the pointer P is incremented by 1 and the initial value "1" is stored in the counter i (S61), and S55 and thereafter. Repeated.

When the smoothing process is executed for all the enlarged characters stored in the information memory 35 (S60: No), the flag TF is reset (S6).
2) Immediately return to the main routine. Further, when the control is started, the flag TF is reset (S50: No), and when all the flags KF are set (S51: No), the process immediately returns to the main routine.

On the other hand, when the normal size key is operated in the main routine (S30: Yes, S31).
・ S37 ・ S39: No, S41: Yes), flag L
F is reset (S42), and the process returns to S30. When any key other than the character key, the enlargement key, the size key, the normal size key, and the end key is operated (S30:
Yes, S31, S37, S39, S41, S43: N
o), the process corresponding to the operated key is executed (S4
4) After that, the process returns to S30. When the end key is operated (S30: Yes, S31 and S37).
-S39-S41: No, S43: Yes), end processing such as storing the document data stored in the text memory 31 in the floppy disk drive device 14 is executed (S45), and this control ends.

As described above, the enlarged pattern data enlarged for each input character is the video RAM 1
4 and once displayed on the display 12, while smoothing the enlarged pattern data and sequentially displaying the processed pattern data on the display 12, when the key is input, the smoothing process is interrupted and the key is pressed. Since the input is prioritized, the key input according to the key operation can be performed quickly and smoothly. Therefore, the display response speed of the input characters can be very fast and the operator's irritation can be eliminated, and the image of the enlarged characters can be confirmed without smoothing processing.
