DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, a data display device A1 according to the present invention includes an input unit 10;
It has an editing processing unit 12, a text processing unit 14, a text buffer 16, a text analysis processing unit 18, a display processing unit 20, a VRAM 32, an output unit 34, and a control unit 36. The display processing unit 20 includes a font processing unit 22, a scroll display control unit 24, a scroll data buffer 26, a scroll control buffer 28
And a text display control unit 30. It is assumed that the data display device A1 is mounted on, for example, a mobile phone K as the information mobile terminal as shown in FIG.

Here, the input section 10 is for inputting text data, and specifically corresponds to an input key.
The edit processing unit 12 is for performing various kinds of edit processing of data. The input section 10 functions as the input means.

The text processing section 14 manages text data stored in the text buffer 16. The text buffer 16 is for storing text data.
Stores data to be displayed in the form of codes.

The text analysis processing section 18 analyzes the text stored in the text buffer 16. For example, the text analysis processing section 18 detects a keyword in a speed change process by a keyword detection described later, and a multi-line data described later. , Processing for detecting control data for displaying multiple lines is performed. This text analysis processing section 18 functions as the above-mentioned detection means.

The font processing section 22 converts character code data into bitmap data. This font processing unit 22 functions as the conversion unit.

The scroll display control section 24 controls the scroll display. The scroll display control section 24 instructs the font processing section 22 to convert the data, reads the data stored in the scroll data buffer 26, and reads the data from the VRAM 32.
When writing into the scroll data buffer, processing such as selection of a read start position in the scroll data buffer 26 and selection of a write timing are performed. In particular, the scroll display control unit 24 has a table in which the correspondence between the shift time (shift timing) and the shift interval, that is, a plurality of shift conditions, as shown in FIG. Controls time and shift interval.

Here, in the table shown in FIG. 2, the shift time as the first condition is 30 ms and the shift interval is 1
As shown in FIG. 3A, the case where bits are shifted indicates that the time for shifting is 30 ms while shifting one dot at a time. Note that one square in FIG. 3 represents one dot, and the bits to be shifted correspond to the dots. In other words, shifting by one bit means shifting by one dot. In the example shown in FIG. 4, shifting by one bit means writing to the VRAM 32 while shifting the start address of the read position by 64 bits.

The second condition shown in FIG. 2 corresponds to the condition shown in FIG.
The third condition shown in FIG. 2 is as shown in FIG.
(C), the fourth condition shown in FIG. 2 becomes as shown in FIG. 3 (d), and the fifth condition shown in FIG. 2 becomes as shown in FIG. 3 (e). become. In FIG. 2, the scroll speed increases as going from top to bottom. The scroll display control unit 24 functions as the display control unit and the scroll display control unit.

Further, the scroll data buffer 26
The bitmap data generated by the font processing unit 22 is stored therein. As shown in FIG.
It has a write area of 00 bits × 64 bits. The area of this writing area is 100 times as large as the writing area of the VRAM 32 described later. The scroll control buffer 28 is a buffer for writing control information for scroll display, and has a configuration corresponding to the text buffer 16. That is, the configuration is the same as that of the text buffer 16. In addition, the text display control unit 30
This is for performing control in the case of normal display, and instructs the font processing unit 22 to perform conversion and writes the generated bitmap data into the VRAM 32.

The VRAM (video RAM) 32 is
This is a RAM for recording data to be displayed on the output unit 34, and has a write area of 96 bits × 64 bits as shown in FIG. The output unit 34 is a display unit for displaying display data, and is configured by an LCD or the like. The control unit 36 controls each unit of the data display device A1.

The operation of the data display device A1 having the above configuration will be described. The data display device A of the present embodiment has the following functions. First, the first function is not only shift time, but also scroll time.
The shift interval is also variable. The second function is to operate the numeric keypad during scroll display to jump to a position corresponding to the operated numeric key in the data being scrolled and scroll again. A third function is to preliminarily determine a keyword to be detected, and to reduce the scroll speed when the keyword is detected in data to be displayed. A fourth function is to display data in a plurality of lines when displaying data configured to display the data in a plurality of lines.

First, the flow of the entire operation will be described with reference to the flowchart shown in FIG. First, it is assumed that a sentence is input by performing an input operation from the input unit 10. Then, the input sentence data is stored in a storage unit such as a memory (not shown).

Then, data to be displayed is selected (S
10). That is, the data to be displayed by the operator is selected from the data stored in the storage unit. At this time, the scroll data buffer 2 selected by the scroll display control unit 24 when writing to the VRAM 32 is selected.
6 is cleared.

Then, first, display is performed in a normal mode (S11). In this normal mode, three-line display is performed, and scroll display is not performed. In this case,
The sentence data as display data is temporarily stored in the text buffer 16 in the form of a code string such as a character code as text data or the like.
The text data in is read out by the text processing unit 14 and sent to the font processing unit 22 according to an instruction from the text display control unit 30. The font processing unit 22 performs a process of converting the code string into bitmap data. Then, the data converted to the bitmap data is written in the VRAM 32 in a form of displaying three lines. VRAM3
2 is output to the output unit 34. Specifically, in this normal mode, the display is performed as shown in FIG. If the user wants to scroll the text in the normal mode, the text is scrolled by a predetermined amount each time the scroll button is pressed. That is, FIG.
When an operation of scrolling upward is performed in the state of FIG.
(B). The scroll direction is a vertical direction.

Next, it is determined whether a scroll display instruction has been given (S12). The scroll display in this case is a scroll display that is displayed in a one-line display so as to flow in the left direction. If it is determined that the instruction has been made, the process proceeds to step S13; otherwise, the process proceeds to step S13. Then, the process returns to step S11. In this one-line display, scrolling leftward is referred to as "leftward scrolling".

In step S13, text analysis is performed (S13). That is, the text analysis processing unit 1
8 analyzes the data to be displayed stored in the text buffer 16. In particular, processing for searching for a predetermined keyword is performed in order to perform the third function. That is, when the mode for performing the third function is set, and a predetermined keyword is set, and when the predetermined keyword is searched, predetermined speed change control data is generated.

When the mode for performing the fourth function is set, control data for displaying a plurality of lines in the data for displaying a plurality of lines is detected. That is, when the data to be displayed is originally data in which at least a part of the text data is formed in a plurality of lines as shown in FIG. It is displayed in a line. Such data is referred to as multi-line data. This may be the case, for example, when such multi-line data is externally read via an interface (not shown). At this time, the multi-line data includes
As shown in FIG. 12B, “1S”, “1E”, “2
It is assumed that control data for displaying multiple lines, such as "S" and "2E", is attached. Here, the control data indicates the number of lines and the start or end position, where “1S” indicates the start position of the first line and “1E” indicates the end position of the first line.
“2S” indicates the start position of the second line, and “2E” indicates the end position of the second line. Then, such multi-line data is stored in the text buffer 16 as one line of information, that is, as a code string, as shown in FIG. That is, the data shown in FIG. 12C can be said to be data for displaying a plurality of lines.

Then, in this text analysis processing,
When the control data for displaying a plurality of lines is detected, the control data is stored in the scroll control buffer 28. that time,
The control data for displaying a plurality of lines is stored at a position corresponding to the storage position in the display data. For example, FIG.
In the example of (c), as shown in FIG. 12 (d), it is stored at a corresponding position in the scroll control buffer 28.

Next, processing for expanding the data to be displayed in the scroll data buffer 26 is performed (S14). That is, data to be displayed among the display data stored in the text buffer 16 is converted into bitmap data in the font processing unit 22 and the bitmap data is
As shown in FIG. 4, the data is developed in the scroll data buffer 26. In the scroll display to the left,
Since the display is performed in one line, the data is developed in the scroll data buffer 26 so that the display is performed in one line.

The scroll data buffer 26
When the mode for performing the third function is set at the same time as the processing for expanding to the above, when the predetermined keyword is detected, the speed change control data generated by the text analysis processing unit 18 is deleted. , Written in the scroll control buffer 28. For example, if the keyword is "", when this word is detected, the speed change control data is generated in step S13, so that the "" data is written in the scroll data buffer 26. The speed change control data is written to a position in the scroll control buffer 28 corresponding to the position that has been set. For example, assuming that data is stored in the text buffer 16 as shown in FIG. 10A, the scroll control buffer 28 stores the speed change control in the corresponding position as shown in FIG. Data is stored. "-1" in the scroll control buffer 28 indicates the speed change control data. The speed change control data has information on the degree of change together with information on whether to increase or decrease the scroll speed. That is, the speed change control data of “−1” means that the scroll speed is reduced by one level. Note that “+2” means that the scroll speed is increased by two steps. As described above,
The scroll speed is changed by detecting the keyword.

In the process of step S14, when the mode for performing the fourth function is set, the data is developed in the scroll data buffer 26 according to the control data stored in the scroll control buffer 28. .

That is, when the bitmap data converted by the font processing unit 22 is expanded in the scroll data buffer 26, the scroll control buffer 28 stores the control data for displaying a plurality of lines. Is developed in the scroll data buffer 26, the data in the scroll control buffer 28 is sequentially checked. Then, when writing bitmap data of a certain character code into the scroll data buffer 26, if the corresponding position of the scroll control buffer 28 is searched and the control data for displaying multiple lines is detected, the scroll display control unit 24 Expansion is performed according to the control data for displaying a plurality of lines. In other words, since the control data of “1S” exists before the data of “Tokyo / Osaka”, the scroll data buffer is searched according to the other control data of “1E”, “2S”, and “2E”. 26. In other words, the data of “Tokyo / Osaka” is sandwiched between “1S” and “1E”, so this is the first row, while the data of “clear and cloudy” is sandwiched between “2S” and “2E”. Therefore, this is expanded in the scroll data buffer 26 so as to be the second line.

Next, scroll display control is performed (S1).
5). That is, as shown in FIG. 8, for the data developed in the scroll data buffer 26, while sequentially moving the head address of the data that is the display range R,
The data for the display range R is read and written to the VRAM 32. That is, since the scroll data buffer 26 has 64 bits in the vertical direction, if it is desired to shift one bit in the horizontal direction, the address shifted by 64 bits (8 bytes) may be set as the head address in the next timing. In this scroll display, the shift is performed according to a predetermined shift condition, that is, the shift interval and the shift time. However, when shifting from step S14, the scroll is performed according to the shift interval and the shift time determined in the initial setting. Is performed. The initially set shift condition is set, for example, to one of the conditions defined in the table of FIG. The specific display mode in step S15 is as shown in FIG. 9. One-line display is a scroll display that sequentially moves to the left.

In the scroll display control in step S15, when the mode of the third function for changing the shift condition when a predetermined keyword is detected is selected, this processing is performed.

That is, as the scroll display control unit 24 shifts the display range in the scroll data buffer 26, the information recorded at the corresponding position in the scroll control buffer 28 is also searched, and the speed change control data is When read, the shift condition is changed according to the control information.

That is, the scroll data buffer 26
In the display range of, it is always checked which character is displayed as text data, and it is checked whether control data is stored at a position in the scroll control buffer 28 corresponding to the character. Then, when the keyword falls within the display range, the speed change control data is written in the corresponding position of the scroll control buffer 28, so that the shift condition is changed according to the speed change control data.

For example, if the keyword is "" and the processing when the keyword is detected is to lower the shift condition by one step, the shift is performed as shown in FIG. When "" is entered in the display range R, speed change control data is detected in the scroll control buffer 28 which is simultaneously searching. Therefore, the shift condition is lowered by one step according to the detected control data. To write to the VRAM 32. For example, in the example of FIG. 2, when scroll display is initially performed under the third condition, display control is performed by changing to the second condition.

When the mode of the fourth function is set and the data in which the control data for displaying multiple lines is inserted as shown in FIG.
Since the data is expanded into a plurality of lines at 14, the data is naturally output to the output unit 34 in the form of a plurality of lines.

Next, it is determined whether the scroll display of the data to be displayed has been completed (S16). That is, it is determined whether the display of the data to be displayed has been completed to the end. Then, when the scroll display is completed, the process ends, and when not, the process proceeds to step S17.

In step S17, when a key operation is performed during the scroll display in step S15, the operated key is determined (S1).
7). Then, if there is an input of an effective key, that is, any of the predetermined keys, step S18
The process proceeds to any one of steps S20 to S20. On the other hand, if the key is not a valid key, scrolling to the left is continued.

If the operated key is a key operation indicating a speed change instruction, a process of changing the scroll speed is performed (S18). That is, when a plurality of shift conditions are provided, and an operation for designating one of them is performed, the control unit 36 analyzes the input key and sends the information to the scroll display control unit 24. .
The scroll display controller 24 controls the scroll data buffer 26 according to the information and the selected shift condition.
Is written to the VRAM 32.
For example, assume that there are five levels shown in FIG.
The shift condition of the condition, that is, the scroll time is 30 ms and the shift interval is 1 bit,
If the shift condition of the condition, that is, an operation of setting the shift time to 10 ms and the shift interval to 3 bits, is performed, the writing to the VRAM 32 is performed under the condition, and the scroll display is performed under the condition (S15). . That is, scroll display is performed while changing the shift condition. For example, in the table shown in FIG. 2, since a plurality of shift conditions are defined for different shift intervals and different shift times, the shift intervals and shift times can be made variable.

On the other hand, if any of the operated keys is a key operation for instructing a change of the display position, a process of changing the display position is performed (S19). That is, a process of jumping the display position is performed. Specifically, the display position is determined based on which one of the ten keys T (see FIG. 15) is pressed. Specifically, the position of the ratio obtained by multiplying the number of the ten key T by 10 is set as the display position. That is, in the display target data, for example, when 3 of the ten keys T is pressed, the position of the data amount of 30% from the head of the display target data is set as the display position. This is because the scroll display control unit 24 knows the start address and the end address of the data to be displayed, calculates the ratio based on the pressed numeric key, and calculates the start address of the display range after the jump. . The data to be displayed here is one piece of text data, and is composed of, for example, one file. After the start address of the display range after the jump is calculated, the data of the display range from that position is transferred to the VRA.
Writing to M32, and then shifting. That is,
Scroll left. For example, if the first address is 101 and the last address is 1000, and a ten key is pressed, (1000-100) × 0.
6 + 100 = 640, and the position of 640 is the head address of the display range after the jump. In other words, Ten
It is possible to jump to a different position according to the input of a different one of the keys.

FIG. 13 schematically shows the process of jumping the display position. As shown in FIG. 13, the display is performed while shifting at the set shift interval until the operation for the jump is performed. When jumping (see FIGS. 13A and 13B), the jump interval is shifted to the calculated display position after the jump, which is different from the set shift interval. (Fig. 13
(C)). After that, scrolling is performed by returning to the previous shift interval (FIG. 13).
(D)).

On the other hand, if any of the operated keys is a key operation for instructing a display change, the display is changed (S20). This display change means display in a normal mode, and when this operation is performed, the display position is set. In other words, data subsequent to the data displayed by scrolling leftward is displayed in the normal mode, that is, in three-line display.
From the code string sent from the first mode when displaying in the normal mode.

As described above, according to the data display device of the present embodiment, not only the shift time but also the shift interval is variable when scrolling to the left, so that even when the shift time is reduced, the shift interval is increased. By doing so, the effect of the afterimage phenomenon in the LCD can be reduced. That is, in FIG. 2, when the condition is shifted from the first condition to the third condition via the second condition, the shift interval is the same and the shift time becomes shorter, so that the image is more susceptible to the afterimage phenomenon. The influence of the afterimage phenomenon can be reduced by increasing the shift interval as in the condition.

According to the data display device of the present embodiment, the user can jump to a predetermined position by operating the numeric keypad, so that a desired position can be displayed by a simple operation. In particular, the mobile phone terminal has a numeric key, and the numeric key can be used effectively to jump to a display location.

Further, a keyword to be detected is determined in advance, and if the keyword is detected in the data to be displayed, the shift condition is changed, so that the scrolled data can be easily read. Further, when displaying data for displaying a plurality of lines, the data is analyzed and a plurality of lines are displayed, so that the scrolled data can be easily read.

It is to be noted that a recording medium (for example, a memory card) holding a program for executing the above processing, that is, the processing according to the flowchart shown in FIG. The flowchart may be executed by installing the program in the provided RAM. In that case, in the flowchart shown in FIG.
Step S18 corresponds to the determination processing of determining a shift interval when scrolling display data, and step S18 corresponds to the storage processing of storing bitmap data in a buffer.
Step S15 corresponds to a reading process of reading data stored in the buffer according to the determined shift interval. Step S19 corresponds to a process of jumping the reading position of the data stored in the buffer according to the key operated by the input operation.

Next, a second embodiment will be described. Second
The data display device A2 according to the embodiment has a configuration substantially the same as that of the first embodiment. However, as shown in FIG. 14, the communication unit 11 and the mailbox control unit 38 are added to the components of the first embodiment. And a mailbox data buffer 40. Here, the communication unit 11 controls communication of electronic mail with the outside. The mailbox control unit 38 manages the mailbox data buffer 40, and the mailbox data buffer 40 temporarily stores the data of the received e-mail. It is assumed that the data display device A2 is also mounted on the portable terminal K as in the first embodiment.

That is, when an e-mail is received via the communication unit 11, the data of the e-mail is stored in the mailbox data buffer 40. afterwards,
The text processing unit 14 extracts text data, that is, a text part, from the e-mail data stored in the mailbox data buffer 40 and stores the text data in the text buffer 16. And this text buffer 16
Are displayed according to the flowchart shown in FIG. That is, the same processing as in the first embodiment is performed.

Therefore, the electronic mail data can be scrolled and displayed not only with the shift time but also with the shift interval, and can be changed by using the ten keys, by changing the shift condition by using a keyword, or by displaying a plurality of lines. Etc. can be performed. In particular, FIG.
When the data for displaying a plurality of lines shown in (c) is received, the data can be displayed in a plurality of lines, and the display can be easily viewed.

Although the embodiment according to the present invention has been described above, the present invention is not limited to the embodiment, and various other modifications are possible. For example, in the above-described embodiment, an example has been described in which the present invention is applied to a mobile phone. However, the present invention is not limited to this, and can be applied to other devices.

The table for determining the shift conditions is shown in FIG.
However, the present invention is not limited to this. For example, the shift condition may be set so that the shift interval is increased as the shift time becomes shorter.

In the above-described jump processing using the numeric keys, the display position is jumped by pressing the numeric key during scroll display. However, the display in the normal mode, that is, the display in the still display state is performed. At this time, it is also possible to make it possible to jump with the ten keys.
