Description

  The present invention relates to a character display method for a mobile terminal, and more particularly to a character display device, a character display method, and a program for displaying a document in which pictograms and characters are mixed.

  In a conventional portable terminal, when displaying a document in which pictograms and characters are mixed, regardless of the pictograms or characters, the character attributes are set one by one, and the pictograms or characters set with the attributes are drawn to represent the pictograms. A document with mixed characters was displayed. Therefore, in conventional mobile terminals, when drawing pictograms or characters in a document in which pictograms and characters are mixed, it is necessary to set attributes one by one regardless of the pictograms or characters. It was hanging. In this specification, a pictogram means a picture (icon) made in a character size, and a character means a character or symbol that can be input by a computer.

  Character and pictographic attributes include color (red, blue, yellow, etc.), font type (Mincho, Gothic, etc.), font type (standard, italic, bold, etc.) There are attributes such as attributes, font size (8, 12, 16, etc.), background colors (white, black, yellow, etc.), and so on.

  Patent Document 1 describes a method for searching for an email containing a specific character string or pictogram from emails stored in a mobile phone. According to the first example of Patent Document 1, mails are searched depending on whether or not a specific character string is included in the subject and / or body of the mail. According to the second example of Patent Document 1, The mail is searched by the color of the pictograph in the mail. Specific codes representing pictographs include codes representing pictographic patterns and codes representing pictographic colors. In Patent Document 1, pictographs are identified by codes representing pictographic colors.

It is a block diagram of the pictogram display device concerning one embodiment of the present invention. It is a figure which shows the example of a concrete display of the document which the character and the pictogram mixed. It is a flowchart which shows the process sequence of the pictogram display routine which concerns on one Embodiment of this invention. It is a figure which shows the registration table of a pictogram.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a block diagram of a pictogram display device according to an embodiment of the present invention. FIG. 1 shows a schematic configuration of a pictogram display device 1 according to an embodiment of the present invention, that is, a mobile phone. An operation unit 11 and a display (LCD) 12 are connected to the pictogram processing unit 10.

  The pictogram processing unit 10 includes a CPU 100, a ROM 101, a RAM 102, an input interface 103, an output interface 104, and a bus line 105 that connects these to be communicable.

  The CPU 100 controls the entire mobile phone and executes a pictogram display program (to be described later) stored in the ROM 101. The CPU 100 calculates and processes the data written in the RAM 102 via the input interface 103 in accordance with a pictogram display program stored in the ROM 101, and outputs the display data of the document obtained by mixing the characters and pictograms as the output interface 104. To the display 12 via The ROM 101 stores a pictographic code registration table to be described later, and the registration table is used to determine whether each character in the document is a pictograph or a character. In this embodiment, SRAM is used for the RAM 102 and FROM is used for the ROM 101.

The operation unit 11 is a unit that operates push buttons and keys provided on the operation unit 11, and inputs operation information to the input interface 103.
The display 12 receives the display data of the document calculated and processed by the CPU via the output interface 104 and displays the document on its own screen.
Characters to be displayed and pictograms displayed by the pictogram display device according to an embodiment of the present invention described below have different character attributes and pictogram attributes.

  FIG. 2 is a diagram illustrating a specific display example of a document in which characters and pictograms are mixed. Depending on the setting of the font size of characters, 20 lines per line (up to 400 characters) can be displayed on the screen by setting the font size of characters. However, in the specific example of FIG. An example in which three lines of documents (up to 30 characters) are displayed on the screen of the telephone 1 with 10 characters per line is shown.

  The character string “ai …… e Yamakawa …… rain in rain” data and the data “wet in rain” following “rain” in the document in which characters and pictograms shown in FIG. Temporarily buffered. The buffer has a predetermined capacity for storing both the document data displayed in the entire screen area and the document data that is not displayed by projecting the screen area. The numbers 0 to 9, 10 to 19, and 20 to 29 shown in the upper part of the character string indicate the character number i of the document in which pictograms and characters are mixed. As shown in FIG. 2, in the example shown in FIG. 2, character display data is stored in character numbers i = 0-2, 4, 5, 7-11, 14-20, and 22-29, and character number i = 3. , 6, 12, 13, and 21 store pictogram display data.

  FIG. 3 is a flowchart showing a processing procedure of a pictogram display routine according to an embodiment of the present invention. Below, when a new document created on the mobile phone 1, an unsent or sent mail document, or a received mail document is displayed on the screen, or a document that is not displayed by protruding the area of the display screen A pictogram display routine according to an embodiment of the present invention that starts when the display area is scrolled up and down or left and right to display a portion will be described. In the method of scrolling and displaying, after processing the entire document including the part that protrudes the display area, the data of the area of the document to be displayed on the screen is transferred according to the scroll operation. There are a method of displaying on the screen and a method of displaying after processing the area of the document to be displayed on the screen in a displayable manner according to the scroll operation. In the present embodiment, the latter method is adopted.

  First, in step S1, the following values are initialized. The count value i of the character to be referred to is set to 0, the length max of the drawn character string is set to 0, and the count value drew of the drawn character is set to 0. Here, the count value i of the character to be referred to corresponds to the character number i shown in FIG. Also, the count value docs of the last reference character of the document is set. This final reference character count value docs is set to the known maximum number of characters that can be displayed on the screen when a document is displayed on the entire display area of the display 12, and is a part of the display area on the screen. When a document is displayed, the number of characters of the document displayed on the screen is set. In the latter case, the number of characters included in the document is counted in advance.

  In step S2, i <max is determined. If i <max, the process proceeds to step S3, and if i ≧ max, the process proceeds to step S11.

  In step S3, it is determined whether or not character data exists in the character with the character number i (hereinafter referred to as the i-th character). If the determination result is YES, the process proceeds to step S4, and if the determination result is NO Terminates this routine. Since character data exists in the blank display, the process proceeds to step S4 when the blank is displayed. Whether or not the i-th character data exists is determined by whether or not a character code corresponding to the character data is registered in advance and stored in the ROM 101.

In step S4, character data of the i-th character is acquired.
The pictogram registration table will be described below.

  FIG. 4 is a diagram showing a pictogram registration table. In the pictogram registration table shown in FIG. 4, the character code, color, and background color corresponding to the pictogram are registered in advance and stored in the ROM 101. In FIG. 4, a pictogram registration number, pictogram, character code, color, and background color are shown in order from the left column. For pictograms, the character code is unique registration data. For pictograms, the color and background color are attributes of the pictogram and can be arbitrarily registered for each pictogram. Thus, for example, a registration number 1 is registered with a heart-shaped pictogram, a character code 123aaa, a red heart color and a white background color, and a registration number 11 is registered with a heart-shaped pictogram, a character code 123aab, a blue heart The white background colors of and are registered. In the present embodiment, as a character attribute, the color is set to black and the background color is set to white. Therefore, the character attribute and the pictogram attribute are different.

Returning again to the flowchart of FIG.
In step S5, it is determined whether or not the i-th character is a pictograph. This determination is made based on whether or not there is a match between the character codes of the pictograms registered in advance in the pictogram registration table as shown in FIG. When the determination result is YES, the process proceeds to step S6, and when the determination result is NO, the process proceeds to step S9. By this process, the appearance of pictograms in the document is searched.

In step S6, after setting the attributes of the (i-drew) characters from the drew-th character to the i-th character in the character string, these characters are drawn. By this process, characters that appear continuously are drawn until a pictogram appears.
In step S7, after setting the attribute of the i-th pictogram, the i-th pictogram is drawn. By this process, characters appearing continuously are drawn until a pictogram appears, and then a pictograph is drawn.
In step S8, the value of i is set to drew (drew = i).
In step S9, 1 is added to i (i = i + 1), and the process returns to step S2. This process counts the number of characters that appear continuously until a pictogram appears.

  On the other hand, when i ≧ max in step S2, the process proceeds to step S11. In step S11, drew <docs is determined. When drew <docs, the process proceeds to step S12. When drew ≧ docs, the process proceeds to step S13.

In step S12, (i-drew) characters from the drew-th character to the i-th character in the character string are drawn.
In step S13, 1 is added to max (max = max + 1), and the process returns to step S2.

The manner in which the document shown in FIG. 2 is displayed according to the flowchart shown in FIG. 3 will be described below.
First, at step S1, i = 0, max = 0, and drew = 0 are initially set.

If NO in step S2, the process proceeds to step S11. If NO in step S11, the process proceeds to step S13, and max = max + 1 = 1 is calculated and the process returns to step S2.
Next, since it is YES at step S2, the process proceeds to step S3, and since it is YES at step S3, the i = 0th character “A” is acquired at step S4. , I = i + 1 = 1 is calculated, and the process returns to step S2.

  This time, it is NO for the second time in step S2, and the process proceeds to step S11. Since NO in step S11, the process proceeds to step S13 and max = max + 1 = 2 is calculated and the process returns to step S2.

  This time, it is the second YES in step S2, and the process proceeds to step S3. Since YES in step S3, i = 1st character “I” is acquired in step S4, and the process proceeds to step S5 because the i-th character is not a pictogram. In step S9, i = i + 1 = 2 is calculated, and the process returns to step S2.

  This time, NO is the third time in step S2, and the process proceeds to step S11. Since NO in step S11, the process proceeds to step S13, and max = max + 1 = 3 is calculated and the process returns to step S2.

  This time, it is the third YES in step S2, and the process proceeds to step S3. Since YES in step S3, the i = 2nd character “U” is acquired in step S4, and the process proceeds to step S5 because the i-th character is not a pictograph. In step S9, i = i + 1 = 3 is calculated, and the process returns to step S2.

  This time, NO is the fourth time in step S2, and the process proceeds to step S11. Since NO in step S11, the process proceeds to step S13, and max = max + 1 = 4 is calculated and the process returns to step S2.

  This time, it is the fourth YES in step S2, and the process proceeds to step S3. Since YES in step S3, i = 3rd character “heart-shaped pictogram: see i = 3 in FIG. 2” is acquired in step S4. Proceeding to S5, since the i-th character is a pictograph, the process proceeds to step S6, and the character “A” is made up of 3 (= i-drew) characters from drew = 0 to the third (i = 3) character. After setting the common attribute, the character “A” is drawn, and after setting the attribute of i = 3rd character “heart-shaped pictogram: i = 3 in FIG. 2” in step S7, “heart-shaped pictogram” Is drawn, drew = 3 is set in step S8, the process proceeds to step S9, i = i + 1 = 4 is calculated, and the process returns to step S2.

  This time, NO is the fifth time in step S2, and the process proceeds to step S11. Since NO in step S11, the process proceeds to step S13, and max = max + 1 = 5 is calculated and the process returns to step S2.

  Thereafter, similarly, steps S2 to S13 are repeatedly executed, and when the last character of the document is reached after drawing the 0th character of the document or after drawing the pictogram, i = 21 in the example shown in FIG. After drawing the pictogram, when i = 29 reaches the last character of the document, YES is determined in step S11, and in step S12, 8 (= i) from drew = 21 to the 29th (i = 29) character. -Drew) After setting the common attribute for the character “forget it because it forgot”, draw the same eight characters and end this routine.

  As described above, in the character display device of the present invention, in a document in which characters and pictograms are mixed, description has been made using an example in which the attributes of characters and attributes of pictograms are different, but the present invention is not limited to this, Character attributes and pictogram attributes match, and characters having different attributes from the character attributes and pictogram attributes, for example, characters having a first attribute drawn in black, pictograms, and second drawn in blue The present invention can also be applied to drawing a document in which characters having attributes are mixed.
