- character type determining section 104 determines whether or not the character is a half-width character. If the character is determined to be a half-width character (YES in S104), the process proceeds to SI06. If not (NO in S104), the process proceeds to S105. In S105, the layout calculation unit 106 determines the position of the full-width character in consideration of the character spacing and line spacing based on the position of the immediately preceding character. In the case of the present embodiment, for vertical writing, the character position of the first character is determined in the upper right part of the display screen in consideration of the margin of the display screen.
- the layout calculation unit 106 counts the number of single-byte characters following the next character after the character whose display position is to be determined. In S107, layout calculation unit 106 calculates the display position of continuous half-width characters. In the case of the present embodiment, the layout calculation unit 106 focuses on the fact that the width of a half-width character is half the width of a full-width character, and adjusts the display so that two half-width characters are displayed side by side in an area of a full-width one character. , Calculates the display position of consecutive half-width characters.
- the layout calculation unit 106 calculates the display position of the punctuation mark.
- the display position is calculated by substituting the coordinates that would have been calculated assuming that the selected character was a full-width character, into a function obtained in advance.
- the function determined in advance is the relationship between the coordinates that would have been calculated if the selected character were a full-width character and the coordinates that would have been calculated because the selected character was a punctuation mark. Required based on
- the layout calculation unit 106 determines whether or not characters can still be displayed on the display unit 107 based on the display positions of the characters calculated so far. If it is determined that characters can still be displayed, the process returns to S102. If not (NO in S109), the process proceeds to S110. In S110, the rate calculation unit 106 creates the rate data of the electronic document based on the display position of each character, and displays the sentence using the display unit 107.
- the input unit 103 reads an electronic document to be displayed (S100).
- the character type determination unit 104 searches the text to be displayed for characters that can be converted to half-width characters, and causes the half-width character conversion unit 105 to convert the searched full-width characters to half-width characters (S 1 0 1).
- the layout calculation unit 106 03014611 is selected (S102). If the coordinates of the display position are to be calculated for the first time, the character displayed at the top of the screen of the display unit 107 is selected. From the second time on, if you want to calculate the coordinates of the display position, select the character next to the character whose display position was previously calculated.
- the character type determination unit 104 determines whether the selected character is a punctuation mark (S103). In this case, since it is determined that the punctuation mark is present (YES in S103), the layout calculation unit 106 calculates the display position of the punctuation mark (S108). The display position is calculated by substituting the coordinates that would have been calculated if the selected character were assumed to be full-width characters, into a previously determined function. The function determined in advance is the relationship between the coordinates that would have been calculated if the selected character were a full-width character and the coordinates that would have been calculated because the selected character was a punctuation mark.

Then, an image is displayed using the display unit 107 (S110).
- the character type determination unit 104 determines whether or not the selected character is a punctuation mark. Since it is not a punctuation mark (NO in S103), character type determining section 104 determines whether or not the character is a half-width character. Since the character is determined to be a half-width character (YES in S104), the layout calculation unit 1 The number of single-byte characters following the character following the character whose display position is to be determined is counted (S106). After counting the number of characters, the layout calculation unit 106 calculates the display position of the continuous half-width character (S107). With reference to FIG.
