The characters input to the input box 22 are not limited to characters, but may be any display units such as codes, symbols, pictograms, and pictograms. In the following description, this character may be simply called a character.
When a character is input from an input device such as a keyboard, the display (display control device) of the present embodiment displays the input character in the input box 22. At the same time, the computer sets the input status to the background corresponding to the input amount. Change color.
 That is, when the upper limit of the number of characters (the amount of the character buffer) to be input to the input box 22 is 15 characters, and when 10 characters are input, the background from the left side of the input box 22 to a position about 67% from the left is input. change.
 As described above, in the present embodiment, even if the width of the input field 22 is shorter than the display width of the characters that can be input, the input character amount (input state) with respect to the character buffer amount can be displayed simultaneously with the input characters. Like that.
 <Configuration of display control device>
 FIG. 2 is a schematic configuration diagram of the display control device of the present invention. In the present embodiment, a display control device is configured by causing a general-purpose computer to execute a display control program.
 As shown in FIG. 2, the display control device 1 of the present embodiment includes, in a main body 11, an arithmetic processing unit 12 including a CPU (central processing unit) and a main memory, and a hard disk in which software for arithmetic processing is stored. (Storage means) 13, an input / output port 14 as a data input / output unit, a communication control unit (CCU: Communication Control Unit) 15 for connecting to a network for communication.
 An operating system (OS) application software is installed on the hard disk 13 of the main body 11.
 The input / output port 14 is connected to input means such as a keyboard and a mouse, and output means such as a display speed.
The arithmetic processing unit 12 realizes functions such as a column display control unit, an input receiving unit, and an attribute acquiring unit by processing based on information from peripheral devices and application software. Further, the arithmetic processing unit 12 secures a character buffer in the main memory based on the application software, and temporarily stores the character being input in this buffer. The arithmetic processing unit 12 functions as a column display control unit, based on display data stored in the hard disk 13 or display data downloaded from another computer via the CCU 15, based on the window 21 or the like. Display input box 22 on the display. In addition, the arithmetic processing unit 12 draws a character input from a keyboard, a mouse, or the like in the input box 22 at the same time as the function of the display unit. Draw input status.
 In addition, as a function of the input receiving unit, the arithmetic processing unit 12 receives a character input to the input field 22 from the input unit such as the keyboard or the mouse, and stores the input into the character buffer of the main memory.
 Further, the arithmetic processing unit 12 acquires attribute information such as the number of characters that can be input in the input box 22 and the number of characters that can be displayed in the input box 22 as a function of the attribute obtaining unit.
 As described above, in the present embodiment, the example in which the arithmetic processing unit 12 of the general-purpose computer executes the predetermined steps according to the display control program to realize the function of the above-described means and configures the display control device has been described. The present invention is not limited to this, and the display control device of the present invention may be an electronic device configured with dedicated electronic circuits for the column display control means, the input receiving means, the attribute acquiring means, and the like.
 <Display control procedure>
 FIG. 3 is an explanatory diagram of steps executed by the display control program. First, the display controller 12 initializes the character buffer and the input column 22 by the function of the column display controller. In the initialization process of the input box 22, the input box 22 in the initial state in which a blank or a default value is described is drawn at a predetermined position in the window 21 (step 100, hereinafter, as in S 100 0). Abbreviated).
 Next, the arithmetic processing unit 12 acquires the attribute of the input box 22 by the function of the attribute acquiring means (S101). In this embodiment, the maximum number of characters that can be input to the character buffer, the font, the character size, and the like are acquired as the attributes.
 Further, the arithmetic processing unit 12 calculates the width mx when the maximum number of characters is actually displayed based on this attribute (S102).
 Then, the arithmetic processing unit 12 waits for a character to be input (S103).
 When a character is input from a keyboard or a mouse, the arithmetic processing unit 12 stores the input character in a character buffer by the function of the input receiving means, and obtains the number of input characters by referring to the buffer (S104) .
The arithmetic processing unit 12 calculates a width (display width) aw when all the input characters are displayed based on the number of input characters and the font to be used (S105). Further, the arithmetic processing unit 12 calculates the relative width Bw of the input character by using the width of the input field as the width of the maximum number of characters according to the following equation (S106).
 B w = width of input field X (a w / m x)
 Then, the arithmetic processing unit 12 redraws the input field 22 by using the function of the display control means so as to change the background color of the portion corresponding to the calculated relative width (S107). Fig. 1 shows the case where 10 characters are input for the number of characters that can be input (15 characters), and the color of the background (shaded area) of about 67% is changed from the left side, and the remaining About 33% of the background is white in the initial state.
 Therefore, when the first character is input, the first character is displayed and at the same time, the background color of about 73% from the left is changed. This indicates that approximately 73% is currently input, and that approximately 27% can be input.
 As described above, when the display control device of the present embodiment is used, the input status can be confirmed based on the ratio of the background color. Therefore, even if the width of the input field is smaller than the display width of the input characters, You can intuitively understand what you are typing and how much you can enter.
 Further, according to the present embodiment, the input amount can be indicated only by the area where the input column is displayed, so that the display area of the display can be effectively used.
 <Modification 1>
 In this modification, the display method of the input status is different from the above-described embodiment. The other configuration is almost the same, so that the description is omitted.
 FIG. 4 shows an example in which the background color is changed when displaying the input status, instead of changing the background color.
 The arithmetic processing unit 12 of this example calculates the relative width of the input character according to steps 100 to 106 of the display control procedure shown in FIG. Redraw the input box 22 to change the color of the frame.
 Fig. 4 shows the case where 10 characters are entered for the number of characters that can be entered (15 characters). The color of the frame (shaded area) of about 67% from the left is changed, and the remaining About 33% of the frame is white in the initial state.
Figure 5 shows an example of changing the text format instead of changing the background and frame colors. are doing.
 In the example shown in the figure, the input box 22 is redrawn so that the characters corresponding to the relative widths are changed to bold characters in step 7.
 In this example, 10 characters can be displayed in the input field at one time.If the ratio of the input characters to the maximum number of input characters is 1% or more and less than 10%, the first character is bold and 10% or more If it is less than%, the character format is changed every 10% so that the second character becomes bold.
 <Variation 2)
 This modified example is a case where the present invention is applied to display control at the time of character input in a web browser, in which the display control program of the present invention is provided as an ablet (for example, a program module that does not depend on ΔS such as JAVA (trademark)). Is shown. Other configurations are the same as those of the above-described embodiment.
 6 to 8 are explanatory diagrams of a display control procedure of the present modification, and FIG. 9 is an explanatory diagram of an input field displayed in the present modification.
 When the user instructs the activation of the web browser, the arithmetic processing unit 12 invokes the corresponding application software from the hard disk 13 to activate the web browser. When the web browser is started, the arithmetic processing unit 12 starts a processing loop for the web page to be browsed (S110).
 When the user inputs the URL of the web page to be browsed, the arithmetic processing unit 12 requests the web page from the web server based on the URL (S111).
 When the web page (data of the web page described in HTML or the like, hereinafter simply referred to as a page) is received from the web server (S112), the arithmetic processing unit 12 analyzes the HTML of the page (S113). ), It is determined whether or not the web page includes a request to generate an ablet for display control (S114).
 If the applet generation request is not included, the display of the page is completed (S116), and the loop for each requested page ends (S117).
If an ablet generation request is included in step 114, the arithmetic processing unit 12 reads out the requested ablet on the hard disk 13 or downloads the ablet from the web server as the ablet generation process, and also downloads the ablet from the web server. Start the software to be executed (for example, a Java virtual machine) (S115). The arithmetic processing unit 12 performs the arithmetic processing based on this ablet, thereby realizing the above-described functions of the column display control unit, the input receiving unit, the attribute acquiring unit, and the like, and executes the later-described steps.
 Note that this example shows a case where a dialog for prompting the user to input an ID and a password is displayed in order to perform an authentication process.
 First, the arithmetic processing unit 12 performs an initialization process (S200). In the initialization processing, a character buffer is secured in a predetermined memory area, and a drawing area is initialized. Next, the arithmetic processing unit 12 acquires, from the server, data necessary for display, that is, the attribute of the input box 22, by the function of the attribute acquiring means (S201). In the present modification, information such as the maximum number of characters that can be input to the character buffer, a normal background color, and a solid background color indicating the input amount is acquired as the attribute.
 The arithmetic processing unit 12 draws an input box 24 in an initial state in which a blank or a default value is described in a designated place on the web page (S202), and starts a processing loop until the user ID is determined (S202). 203).
 In the processing loop, the arithmetic processing unit 12 sets the maximum number of characters n, the normal background color (colorl), and the painted background color (color2) in the input field 24 (S300), and waits for input (S301). .
 If an input is made, it is determined whether or not the processing by the Enter key or the confirmation button (not shown) has been completed. If the processing has been completed, the user ID determination processing loop ends (S204). It performs user ID authentication processing (S205) and final page acquisition (S206).
 If not, the arithmetic processing unit 12 receives the input character by the function of the input receiving unit, stores the character in the character buffer, and draws the character stored in the character buffer in the input box 24 (S303). ).
 Further, the arithmetic processing unit 12 calculates the width mx when the maximum number of characters is actually displayed based on the attribute (S304).
Then, the arithmetic processing unit 12 obtains the number of input characters stored in the buffer (305), and displays all the characters input from the number of input characters and the font to be used. Width (display width) aw is calculated (S306).
 Further, the arithmetic processing unit 12 calculates the ratio (the relative width of the input character) Bw of the display width of the input character to the width of the input field according to the following equation (S307).
 B w = width of input field X (a w / m x)
 Then, the arithmetic processing unit 12 redraws the input column 24 by using the function of the column display control means so as to change the background color of the portion corresponding to the calculated relative width (S 308). Fig. 9 shows a case where 10 characters are input for the number of characters that can be input (15 characters), and the color of the background (shaded area) of about 67% from the left is changed to a solid background color The remaining 33% of the background is the normal background color.
 As described above, according to the present modification, even in the input field on the web page, the input status can be easily grasped even if the width of the input field is set short as in the above-described embodiment.
 << Embodiment 2 >>
 The present embodiment is different from the above-described first embodiment in control for displaying a display range (input position) as an input state, and other configurations are substantially the same. The same elements as those in the above-described embodiment are denoted by the same reference numerals, and the description thereof will not be repeated.
 FIG. 10 is an explanatory diagram of a display control procedure according to the present modification, and FIG. 11 is an explanatory diagram of an input field displayed in the present modification.
 As shown in the figure, the display control unit 12 first performs a process of initializing the character buffer and the input column 25 by the function of the column display control unit. In the initialization process of the input field 25, an input field 25 in an initial state in which a blank field or a default value is described is drawn at a predetermined position of the window 21 (step 400).
 Next, the arithmetic processing unit 12 determines whether or not scrolling has been performed (S401). The scrolling is performed by, when a character is input beyond the width of the input field 25, adding a new character to the right end and shifting the previous character to the left. In addition, when characters are input beyond the width of the input shelf 25, the scroll moves the cursor 31 to the left end or the right end of the input box 25, and the characters in that direction are moved. This is also done by displaying them sequentially.
If it is determined that the scroll has been performed, the arithmetic processing unit 12 acquires the number of input characters by referring to the character buffer (S402). Also, the arithmetic processing unit 12 obtains the width of the input field, the font used, the character size, and the like as attributes of the input field 25 by the function of the attribute obtaining means, and based on this attribute, the width when all the input characters are displayed. aw is calculated (S403).
 Further, the arithmetic processing unit 12 acquires a distance p os X from the top of the scrolled input character string to the left end of the input box 25 (S404). For example, in FIG. 11, since the third character of the input character string is displayed at the left end of the input field, the character width of the previous two characters, pOSX, is obtained.
 Next, the arithmetic processing unit 12 obtains the ratio (relative character width) Bw of the width of the input box 25 to the display width aw of the input character obtained in step 403 by the following formula (S405).
 Bw = input field width X (input field width aw)
 Further, the arithmetic processing unit 12 obtains the background color change start position p os B by the following equation (S406).
 p os B = p os x X (input field width / aw)
 Then, the arithmetic processing unit 12 performs drawing by using the function of the column display control means so as to change the background color of the input column 25 from the calculated position p os B by the relative character width Bw (S407). FIG. 11 shows a case where the third to thirteenth characters of the inputted fifteen characters are displayed.
 FIG. 12 shows a case where the fifth to fifteenth characters are displayed by scrolling.
 As a result, the user can easily grasp the position of the displayed character, that is, the position of the displayed character, that is, the position to be edited. As described above, according to the present embodiment, even when the width of the input field is smaller than the display width of the input characters, the input status such as “Where the input character string is displayed” is displayed. Can be shown.
 Further, according to the present embodiment, the input position can be indicated only by the area where the input field is displayed, so that the display area of the display can be effectively used.
In the present embodiment, the display position for the input character is shown. However, the number of characters that can be input as attribute information is acquired, and the character width when all the number of characters is displayed is set to aw, and steps 403 to 407 are performed. , Relative width Bw, start position pos B First, the background color may be changed from the start position P os B by the width of the relative width B w to indicate where the position in the inputtable character range is displayed, <Modification 1 〉
 In this modification, the display method of the input status is different from the above-described embodiment. The other configuration is almost the same, so that the description is omitted.
 FIG. 13 shows an example in which the color of the frame is changed instead of changing the background color when displaying the input status.
 The arithmetic processing unit 12 of the present example obtains the relative width B w of the input character and the change start position p 0 s B according to steps 40 0 to 40 6 of the display control procedure shown in FIG. In step 7, the input field 25 is redrawn so as to change the color of the frame having the relative width Bw from the change start position posB.
 Fig. 14 shows an example of changing the character format instead of changing the background and frame colors.
 In the example shown in the figure, the input field 25 is redrawn in step 407 so that the characters corresponding to the relative width are changed to bold characters.
 In this example, the number of characters that can be displayed at one time in the input field is 11 characters, so if the change start position is 0% or more and less than 9% of the width of the input field, change from 1st character to 9% and less than 18% If there is, the format of 8 characters is changed by shifting the starting position every 9%, like the third character if it is 18% or more and less than 27%.
 <Variation 2)
 FIG. 15 simultaneously shows the input amount displayed by the control procedure of FIG. 3 and the position displayed by the control procedure of FIG.
 In the input field 26 in the figure, the input amount and the position are displayed by the background color.
 In the input field 27 in the figure, the input amount and the position are displayed by the color of the frame. <Modification 3)
 FIG. 16 shows an example in which, when an input character is input over a plurality of lines, the display position is displayed in a rectangular shape in the input field.
In this modified example, in addition to the display position in the width direction of the input field 28, the height direction is also displayed in the display start position and the input field 28 with respect to the number of input lines. The display position is shown by calculating the ratio of the rows and changing the background color of the corresponding part in the width and height directions.
 << Embodiment 3 >>
 The present embodiment is different from the above-described first embodiment in control for displaying that the number of input characters has exceeded the maximum value of the number of input characters, and other configurations are substantially the same. The same elements as those in the above-described embodiment are denoted by the same reference numerals, and the description thereof will not be repeated. FIG. 17 is an explanatory diagram of a display control procedure of the present modification, and FIGS. 18 and 19 are explanatory diagrams of input fields displayed in the present modification.
 The display control unit 12 first performs initialization processing of the character buffer and the input box 29 by the function of the display control means. In the initialization process of the input box 29, an input box 29 in an initial state in which a blank or a default value is described is drawn at a predetermined position of the window 21 (step 500).
 Next, the arithmetic processing unit 12 acquires the maximum number of characters (maximum number of characters) for which input is valid as an attribute of the input field 25 by the function of the attribute acquisition means (S501).
 Then, the arithmetic processing unit 12 waits for input (S502), and when a character is input, acquires the number of input characters by referring to the character buffer (S503).
 Further, the arithmetic processing unit 12 acquires the initial value of the background color (white in this example) and the changed value (red in this example) as the attributes of the input field 25 by the function of the attribute acquisition means. The period value is set (S504).
 Next, the arithmetic processing unit 12 determines whether or not the number of input characters has exceeded the maximum number of characters (S505), and if so, sets the background color to red (S506). Then, the arithmetic processing unit 12 draws an input field in a state where the background is red and the characters are input (S507). On the other hand, if it is determined in step 505 that the number of input characters does not exceed the maximum number of characters, the arithmetic processing unit 12 draws an input field in which the characters are input while the background is white.
 As described above, according to the present embodiment, whether the number of input characters exceeds the maximum number of characters (input status) can be displayed by the background of the input column, and it can be easily grasped whether the number of characters exceeds the maximum number of characters.
Therefore, in fields such as questionnaire input fields, the maximum number of characters is 15 characters. However, if the user enters 30 characters and presses the send button, the user is prevented from actually being cut off and registered with 15 characters without noticing.
 Further, according to the present embodiment, the input status such as “whether or not the maximum number of characters has been exceeded” can be indicated only by the area where the input field is displayed, so that the display area of the display can be effectively used. .
 This embodiment is performed simultaneously with the first embodiment. When the number of input characters is equal to or less than the maximum number of characters, the background color of a portion corresponding to the input amount is changed to a first background color (for example, green). The remaining background may be the initial background color (eg, white), and if the number of input characters exceeds the maximum number of characters, the background color may be changed to the second background color (eg, red). In addition, this embodiment is performed simultaneously with the second embodiment. If the number of input characters is equal to or less than the maximum number of characters, the display position is indicated by a first background color (for example, green), and the number of input characters exceeds the maximum number of characters. In this case, the background color may be changed to a second background color (for example, red). If the number of input characters is less than the maximum number of characters, the input amount is indicated by the first background color (for example, yellow) and the display position is indicated by the second background color (for example, green). For example, the background color may be changed to a third background color (for example, red). Further, instead of the background color, the frame color may be displayed.
 It should be noted that the display control device and the display control program of the present invention are not limited to the above-described embodiment, and it is needless to say that various changes can be made without departing from the gist of the present invention. Industrial applicability
 As described above, according to the present invention, even when the width of the input field is set smaller than the display width of the number of characters that can be input, the input status can be easily grasped.
 The present invention is not limited to the general-purpose computer described in the above embodiment, but can be similarly applied to a telephone, a FAX, an electronic calculator, and the like as long as the device can input characters while confirming the input characters in an input box.
 《Computer readable recording medium》
A program (display control program) that causes a computer to realize the above functions can be recorded on a computer-readable recording medium. And con The function can be provided by reading and executing the program on the recording medium in the evening.
 Here, a computer-readable recording medium is a recording medium that stores information such as data and programs by electrical, magnetic, optical, mechanical, or chemical action and can be read from a computer. Say. Examples of such a recording medium that can be removed from a computer include a flexible disk, a magneto-optical disk, a CD-R0M, a CD-R / W, a DVD, a DAT, an 8 mm tape, and a memory card.
 In addition, a recording medium fixed to the computer includes a hard disk and a ROM (lead only memory).
