Abstract

PROBLEM TO BE SOLVED: To provide a display control device by which sentences are made easy to read, scrolling operations are reduced, and quoted portions can be clearly displayed as quoted portions, even in apparatuses having small display devices. SOLUTION: When a linefeed exists in a sentence, line-feeding is not performed and some kind of mark, for example '↓' is displayed. In this case, for distinguishing it from letters in the sentence, a color of the mark '↓' or a background color thereof is made different from that of the sentence or a background color thereof. If there is a tab, tab spaces are not displayed and the tab is replaced to some mark, for example '→', to be displayed. In the same way, by changing the color of the mark or a background color, it is made clear that the mark '→' is different from the characters in the sentence. If a quotation mark, for example '>' exists, the letters or the background are made to be one color, until the next linefeeding. By making the color different from that of the body sentences, it can be clearly indicated that the portion is a quoted part.

All the character strings in the received mail are displayed by simply folding them according to the width of the display device.

When there is a line break in the text of the received mail, the line after that is displayed as a blank and displayed from the next line. Also, if there is a tab in the text of the received email,
Display blanks depending on the tab. Further, when replying to a received mail, it is customary to add a quotation mark, for example, “>” to the beginning of the sentence in the quoted portion from the text of the received email to clearly indicate the quoted portion. When the quoted portion is quoted again, a quotation mark such as ">>" is added at the beginning of the sentence. When such an email is received, a quotation mark is displayed at the beginning of the line.

Specifically, when a mail of the style shown in FIG. 3 is sent from the sending side, the receiving side displays the text sentence from the sending side as it is, so that the receiving side display device is small. In particular, when the number of characters in one line is small, the number of lines increases accordingly. For example, when the sentence of FIG. 3 is displayed on the display device of 4 lines with 6 characters per line, the display state is as shown in FIG. The solid line in FIG. 4 indicates the range that can be displayed on one screen.

The memory 14 stores the digital signal output from the base band unit 10 once. When the input character string data stored in the memory 14 or input by the character input means 13 is temporarily stored in the memory 14 and there is data to be displayed in the data stored in the memory 14, the replacement target control code detection means 2 CPU 1 for outputting display data to the baseband unit 10 for outputting display data to the baseband unit 10, and temporarily storing input character string data, transmission data, and reception data output by the CPU 1, and if necessary, the CPU 1 The memory 14 for outputting to and the character input for outputting the input character string data to the CPU 1, which is used for inputting characters by the user. Means 13, replacement target code table 3 for storing control codes preset as replacement target codes, replacement target control code detecting means 2 for detecting control codes, and quotation mark detected by replacement target control code detecting means 2. Quotation mark counter 4 to count
And a replacement correspondence table 7 that stores (after replacement) graphic character codes or / and color control tags corresponding to the control codes to be replaced (control codes such as line feed, tabs, quotation marks).
A character code replacement means 6 for replacing and deleting the control code, a color control means 5 for controlling the replaced character color or background color, and a display means 8 for outputting the text sentence after the replacement processing to the display. And a display 9 for displaying text sentences.

In the display controller having the above structure,
When displaying the received mail, the text of the mail is CP
It is taken out from the memory 14 by U1 and output to the replacement target control code detecting means 2. The replacement target control code detecting means 2 refers to the control codes, "line feed", "tab", ">", etc., which are preset in the replacement target code table 3, and according to the text sentence of the display data input from the CPU 1. Detect the control code.

When the replacement target control code detecting means 2 detects the control code "line feed", the character code replacing means 6
A control code "line feed" is added to the symbol corresponding to the control code "line feed" stored in the replacement correspondence table 7, for example, "↓".
Is replaced and output to the display means 8. The color control means 5 outputs color information to the display means 8 so that this symbol “↓” is displayed in a character color or background color different from the text. Display means 8
Outputs a signal to the display 9 so as to display according to the information.

Is replaced and output to the display means 8. The color control means 5 outputs color information to the display means 8 so that this symbol "→" is displayed in a character color or background color different from the text. Display means 8
Outputs a signal to the display 9 so as to display according to the information.

When the replacement control code detecting means 2 detects a reference symbol, for example, a control code ">", the reference symbol counter 4 counts the number of consecutive control codes ">". The character code replacement means 6 deletes consecutive control codes “>”. The color control means 5 displays color information such that one sentence from the detected quotation mark to the next line feed is displayed in accordance with the count number of the quotation mark counter 4 and in a character color or background color different from the text. Output to the means 8. The display 9 displays a sentence according to the output of the display unit 8.

When the above processing is performed and the sentence as shown in FIG. 3 is displayed, it becomes as shown in FIG. Here, since "Sashisuse Sotetsu Tetsuto" is a citation, it has a character color or a background color different from the text. In addition, "Nani Nune no Hifueho" is a sentence with two quotation marks, so it has a different text color or background color from the text and "Sashisuseso Satotsuto" and clearly shows the quotation relationship. Control code "tab" is "→"
, And the control code "line feed" is replaced with "↓",
No line break processing is performed. The symbol "→" after replacement,
"↓" has a character color or background color different from that of the text or the quoted text, and clearly indicates that it is different from the symbol existing in the text. By this processing, in this example, the number of lines that cannot be displayed on the display at one time can be reduced from four to three. Even if the quoted portion is folded and displayed, the quoted relation can be displayed in an easy-to-understand manner by changing the character color or the background color.

Next, an explanation will be given of the case where the text displayed in this way is edited to reply. A character input from the user is input from a character input means 13 such as a keyboard, and is temporarily stored in the memory 14 by the CPU 1. CP
When it is necessary for the U1 to display the input character string data as the main text as a new input, the input character string data is sent from the CPU 1 to the color control means 5 in order to display it with a color. The color control means 5 outputs color information to the display means 8 so as to display in a character color or background color different from the quoted portion displayed in the character string data. The display means 8 outputs a signal to the display 9 so as to display according to the information. By this processing, the quoted portion and the newly input portion are clearly distinguished by the character color or the background color, and the quotation relationship can be more clearly displayed and can be displayed in an easy-to-read manner.
