In an apparatus for displaying a character string in the form of a list, it is rare that the list character strings of all the lines fit within the physical display screen size. As a means to move to the target line position, select an arbitrary position from the whole display and return to the normal display to move the screen display, move the cursor, or move the slider for window scrolling, the screen display range Was switching dynamically. Therefore, in order to display the character string of the line at the target position from the entire display state on the screen, it is necessary to roughly return to the normal display and then scroll further to the target line position. , It is necessary for the operator to constantly look at the screen carefully, and there is a problem that the operator himself tends to be tired. In other words, there is a problem that it takes a long time to locate the target line position. Further, in the screen scrolling method by moving the cursor, since the system itself is required to operate at a high speed, it is difficult to apply the method to a device having a low display function. In the method of scrolling the screen with the scroll slider, the operability is good under the assumption that a pointing device such as a mouse is used, but the operator always keeps watching the screen carefully to position it on the target line like the whole display method There is a need.

An object of the present invention is to provide a method and apparatus for displaying a character string which can be reliably positioned at an arbitrary target line position by a simple operation and displayed on a screen.

In order to achieve the above object, the present invention provides a character string display method for displaying a character string arranged in a list on a logical screen on a physical screen.
Character strings for a predetermined number of lines are divided into blocks, and the blocked character strings are displayed on the physical screen. In addition, the character string displayed as a block in the physical screen in response to the movement operation of the character string is moved in the physical screen, and the character string that is blocked in the normal display instruction operation is expanded into a non-blocked state. It is characterized by being displayed within.
Further, in a character string display device for displaying a character string arranged in a list form on a logical screen in a physical screen, a character string for a predetermined number of lines is blocked, and the blocked character string is displayed on the physical screen. It is characterized by having a means for causing. Also, a first operating means for instructing a character string moving operation, a second operating means for instructing a normal display state, and a block in the physical screen in response to the character string moving operation by the first operating means. Means for moving the displayed character string in the physical screen, expanding the blocked character string in a non-blocked state in response to the normal display instruction operation by the second operation means, and displaying the block in the physical screen. Features.

With such a configuration, the target character string line is not displayed in the currently displayed screen.
If it is known that the target line can be displayed by moving the screen up and down n lines, the character string for a plurality of lines can be moved by one cursor movement operation, and the target character string can be displayed. .

[0017]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an overall configuration of a list display device according to an embodiment of the present invention. In FIG. 1, reference numeral 101 denotes a display device; 102, a central processing unit serving as a character string display device having a built-in list display function; 103, an auxiliary storage device storing character string information to be displayed in a list;
Reference numeral 04 denotes a mouse for performing an auxiliary operation, and reference numeral 105 denotes a keyboard. The central processing unit 102 executes the list display program 10
6 to display and edit the character string information stored in the auxiliary storage device 103. In the present embodiment, a list block display program 107 that operates in cooperation with the list display program 106 is mounted.

FIG. 2 shows an outline of functions and operations for displaying a character string at an arbitrary line position on a screen from a normal list display state. FIG. 2A shows a screen 201 displaying an intermediate line of character information data, and a button 20 for displaying the screen as a block line.
2 and a cursor 203 indicating a display / edit target.
FIG. 2B shows a screen 204 during block row display, a button 205 for returning to normal visual display, and a cursor 206 indicating the position of a block including the display edit target row. FIG.
Represents a screen 207 that has returned to the normal visible display state from the screen displaying the block lines.

When the list display program 106 is started,
From the state where the character string information stored in the auxiliary storage device 103 is displayed in the list display format,
Is pressed with the mouse 104, the screen shifts to a block row displaying screen 204. This operation is an alternative to pressing the button 202 with a mouse by pressing a specific key in the keyboard 105 or a combination operation by simultaneously pressing a key and a key. That is, it means that the state changes from the normal list display screen state to the block line display screen state by some action. At this time, the cursor in the block line display screen state is present on the block display line including the line normally displayed in the list on the screen 201 up to now. On the screen 204 during the display of the block line, the cursor 206 can be moved to an arbitrary block line by a cursor up / down operation of the keyboard 105 or a line selection operation by the mouse 104.

When a button 205 is pressed with the mouse 104 on the screen 204, a normal visible state list display screen 207 (FIG. 3) is displayed. At this time, the line of the character string displayed on the screen 207 is the cursor 20 on the block line.
6 (FIG. 2B) is the row corresponding to the block in which it exists. This operation is an alternative to pressing the button 205 with the mouse 104 by pressing a specific key in the keyboard 105 or a combination operation by simultaneously pressing the key and the key. That is, it means that the state is shifted from the normal block line display screen state to the list display screen state by some predetermined action. A feature of the present invention is that, although operation with a mouse is also possible, movement of the screen display to an arbitrary line position is realized only by a simple keyboard operation.

FIGS. 4 and 5 show a list display program 1.
List block display program 1 called from 06
It is a flowchart which shows the outline | summary of the process of 07. First,
In step 401, a mouse operation or a keyboard input from the operator is accepted when the list display program 106 is displaying and editing character string information in a normally visible display state. Next, in step 402, it is determined whether the operator has pressed the mouse on the block line display button or performed an operation for shifting to block line display from the keyboard 105.
If it is determined that the block line display button has not been pressed with the mouse or the operation for shifting to the block line display has not been performed from the keyboard 105, the process returns to step 401, and the list display program 106 displays the character information in the normal visible state. Display and edit.

If it is determined in step 403 that the block row display button is pressed with the mouse or an operation for shifting to block row display is performed from the keyboard 105, the process proceeds to step 403. In step 403, an operation for displaying a block line is performed, and the number of block display lines is obtained from the total number of lines of the character information data. In step 404, the screen display state is switched from the normal list display to the block line display based on the number of block lines calculated in step 403. Thereafter, the block line display state is set until the display is explicitly switched to the normal list display state. In step 405,
Waiting for operation in block line display state.

When the operator operates the mouse 104 or the keyboard 1
If the operation from step 05 is performed, the process proceeds to step 406. If the operation of moving the cursor upward with the keyboard 105 is performed and there is a block line that can be moved upward, the cursor is moved to one line in step 407. Move upward. Similarly, the process proceeds to step 407 and the keyboard 105
When the operation of moving the cursor downward is performed by the operation and there is a block line that can be moved downward, the cursor is moved one line upward in step 409. In the mouse click operation, the determination is made in step 410. If the clicked position of the mouse 104 is a part of the block display line, the process proceeds to step 411, and the cursor is moved to the block line specified by the mouse 104.

If any other operation has been performed, the process proceeds to step 412, where it is determined whether the normal display button has been pressed or a keyboard operation for shifting to the normal list line display has been performed. In this determination, when the normal display button is not pressed and the keyboard operation for shifting to the normal list line display is not executed, the process returns to step 405, and
Waiting for operation in block line display state.

If it is determined in step 412 that the normal display button has been pressed or the keyboard operation for shifting to the normal list line display has been executed, the process proceeds to step 413, where the block indicated by the cursor in the normal visible state is displayed. Step 4 displays the character string of the line corresponding to the display line on the screen.
Proceed to 14. In step 414, if the display editing operation of the character string information is not completed, the process returns to step 401 and the list display program 106 is continued. The processing of the list block display program 107 in the present embodiment is in the range from step 403 to step 412.

FIG. 6 is a diagram showing a correspondence relationship between a logical list line existing when character string information is displayed in a list format and a block list display line. When the total number of lines of character information data to be developed in the logical screen is defined as N and the number of lines per block is defined as L, the number B of lines to be displayed in a block
Can be expressed by the following equation 1.

[0028]

B = (N + (L-1) / L where N = the total number of lines of character string information, L = the number of lines per block. For example, if N = 100 and L = 40, then B = 139
Truncation below / 40 at /40=3.5 results in B = 4 rows. This is because the number of lines to be displayed as a block is four, and the cursor 206 indicating the position of the block on the screen 204 is moved by one line, so that the character string in the visible state is L = 40.
It means that line movement is possible.

Therefore, according to the present embodiment, an information terminal having a small physical display screen, for example, a portable telephone 701 having a liquid crystal screen 702 as shown in FIG. It will be extremely effective. Also, the approximate position of the information that the user wants to see in the information on the logical screen in advance (for example, beginning of sentence, end of sentence, etc.)
If the information is known, the target information can be reached in a short time by scrolling to that part while keeping the block display.

[0030]

As described above, according to the present invention, the cursor moving operation in the block row display state allows
Selective movement to the target display position can be performed by a fraction of the operation of character string display in the ordinary list format, and the time required to reach the target information is significantly reduced compared to the conventional method, and operability is improved. Can be improved.
