The line width adjustment unit 123 adjusts the line width of the enlarged / reduced data based on the determined line width, and generates character or graphic data (also referred to as “display data”) used for display. The line width adjustment unit 123 outputs the generated display data to the display unit 130.

  The display unit 130 displays characters and graphics based on the display data input from the line width adjustment unit 123.

FIG. 4 is a flowchart illustrating an example of processing contents of the display device 100 according to the present embodiment.
(Step S401) The handwriting input unit 111 receives characters and figures from the user 200 (FIG. 1). The handwriting input unit 111 generates drawing data based on the input of the user 200. The handwriting input unit 111 outputs the generated drawing data to the input size measurement unit 121. Then, the process proceeds to step S402.

(Step S <b> 402) The command input unit 112 determines whether there is a command input for enlargement / reduction of drawing data from the user 200. Here, as an example, command input by pinch-in / pinch-out will be described.
When pinch-in / pinch-out is performed (YES), the command input unit 112 detects the touch of the user 200 with two fingers. The command input unit 112 generates touch position related information based on the detected two touch areas. Here, the touch position related information is the above-described enlargement / reduction information. The command input unit 112 outputs the generated touch position related information to the enlargement / reduction unit 122. Then, the process proceeds to step S404.
When the pinch-in / pinch-out is not performed (NO), the display unit 130 displays the handwritten input character or figure without enlarging / reducing (step S403). Then, it returns to step S401.

  (Step S404) The input size measuring unit 121 acquires drawing data from the handwriting input unit 111, and measures the size of characters and figures. The input size measurement unit 121 generates size information based on the measured size of characters and figures. The input size measurement unit 121 outputs the drawing data and the size information to the enlargement / reduction unit 122. Then, the process proceeds to step S405.

  (Step S <b> 405) The enlargement / reduction unit 122 acquires touch position related information from the command input unit 112. The enlargement / reduction unit 122 determines the enlargement / reduction ratio of the drawing data based on the touch position related information. The enlargement / reduction unit 122 acquires drawing data and size information from the input size measurement unit 121. The enlargement / reduction unit 122 performs enlargement / reduction of the drawing data based on the size information and the enlargement / reduction ratio of the drawing data, and generates enlargement / reduction data. The enlargement / reduction unit 122 outputs the enlargement / reduction data and the enlargement / reduction ratio to the line width adjustment unit 123. Then, the process proceeds to step S406.

  (Step S406) The line width adjustment unit 123 acquires the enlargement / reduction data and the enlargement / reduction ratio from the enlargement / reduction unit 122. The line width adjustment unit 123 determines the line widths of characters and figures used for display from the acquired enlargement / reduction data and enlargement / reduction ratio. The line width adjustment unit 123 changes the line width of the enlarged / reduced data based on the determined line width, and generates display data. The line width adjustment unit 123 outputs the generated display data to the display unit 130. Then, the process proceeds to step S407.

  (Step S407) The display unit 130 displays characters and figures based on the display data input from the line width adjustment unit 123.

  The touch position related information includes the position of the touch area and the movement information of the touch area. In enlargement / reduction by pinch-in / pinch-out, the enlargement / reduction ratio can also be determined based on the speed or acceleration of change in the distance between the two touch areas. In the present embodiment, the determination of the enlargement / reduction ratio in the enlargement / reduction unit 122 is not limited to a specific method.

  The enlargement / reduction command is not limited to pinch-in / pinch-out with the thumb and forefinger, and other fingers, pens, or the like may be used. In addition, the user 200 may specify the size of characters and figures by a completely different method such as directly inputting the enlargement / reduction ratio as a numerical value or adjusting the scroll bar on the screen. Further, the user 200 may determine the size in each of the X-axis direction and the Y-axis direction.

FIG. 5A and FIG. 5B are diagrams illustrating a modification example of an enlargement / reduction command input method and display in the present embodiment.
FIG. 5A is an example of a display when the user performs handwriting input.
FIG. 5B is an example of a display when the user completes handwriting input.
5A and 5B, the display unit 130 displays character strings 300a and 300b, respectively. The character string 300a is a character string input in an arbitrary size at an arbitrary position of the handwriting input unit 111 by the user. The character string 300b is a character string 300a that is reduced in accordance with a ruled line drawn in the horizontal direction after completion of handwriting input.

  When characters or figures are input to the handwriting input unit 111, the display unit 130 displays the command input unit 112a in order to determine completion of input. When the command input unit 112a detects a user's touch, the input size measurement unit 121 measures the size of characters and figures input to the handwriting input unit 111, and generates size information. The input size measurement unit 121 outputs the generated size information to the enlargement / reduction unit 122. The enlargement / reduction unit 122 determines the enlargement / reduction rate based on the size information input from the input size measurement unit 121 and the interval between the ruled lines displayed on the display unit 130. The enlargement / reduction unit 122 enlarges / reduces the drawing data of the character string 300a based on the enlargement / reduction ratio and the size information, and generates enlargement / reduction data. The enlargement / reduction unit 122 outputs the generated enlargement / reduction data and the enlargement / reduction ratio to the line width adjustment unit 123. The line width adjustment unit 123 adjusts the line width of the enlarged / reduced data input from the enlargement / reduction unit 122 based on the enlargement / reduction ratio, and generates display data. The line width adjustment unit 123 outputs the generated display data to the display unit 130. The display unit 130 displays the character string 300b between the ruled lines based on the display data input from the line width adjusting unit 123. As described above, the control unit 120 may perform the enlargement / reduction process by using the command input unit 112a to detect the completion of the handwriting input as a trigger.

The process of the input size measuring unit 121 (FIG. 3) will be described in detail with reference to FIG.
FIG. 6 is a diagram illustrating an example of measurement of the size of characters and figures according to the present embodiment.
FIG. 6 shows the upper left of the handwriting input unit 111 as the origin of the XY two-dimensional coordinate system.
FIG. 6 shows a state in which the handwriting input unit 111 has input the hiragana character 300c “a”. The input size measuring unit 121 detects maximum values Xmax and Ymax and minimum values Xmin and Ymin of coordinates in the X-axis direction and the Y-axis direction in the drawing data. The input size measuring unit 121 determines the sizes Xi and Yi of the character 300c based on the following equation.
Xi = Xmax-Xmin
Yi = Ymax−Ymin (1)
The input size measurement unit 121 outputs Xi and Yi and coordinates (Xmin, Ymin) to the enlargement / reduction unit 122 as size information.

  The coordinate information included in the size information is not limited to (Xmin, Ymin). For example, the coordinate information may be coordinates such as (Xmax, Ymax) that can specify an area including characters and graphics. Further, the size of characters and figures is not limited to the above format. For example, the size of a character or figure may be a region such as the smallest circle that encloses the character or figure and is defined by a radius and center coordinates. Further, for example, depending on the enlargement / reduction format such as pinch-in / pinch-out, the input size measurement unit 121 does not measure the size of characters and figures, and outputs the entire input area of the handwriting input unit 111 as size information. May be.

An example of specific processing by the enlargement / reduction unit 122 and the line width adjustment unit 123 will be described in detail.
The enlargement / reduction unit 122 acquires drawing data and size information from the input size measurement unit 121. The enlargement / reduction unit 122 enlarges / reduces the drawing data based on the size information and the enlargement / reduction ratio R, and generates enlargement / reduction data. Specifically, the enlargement / reduction unit 122 generates enlargement / reduction data by enlarging / reducing an area in the drawing data specified by the size information in each of the X-axis direction and the Y-axis direction. The size Xo in the X-axis direction and the size Yo in the Y-axis direction of the characters and figures after enlargement / reduction are expressed by the following equations.
Xo = Xi x R
Yo = Yi × R (2)

Further, the line width Ws of the enlarged character or figure is expressed by the following equation using the line width Wi of the input drawing data.
Ws = Wi × R (3)
In the present embodiment, the line width adjustment unit 123 may or may not grasp the line width Wi of the input drawing data.

The enlargement / reduction unit 122 outputs the generated enlargement / reduction data and the enlargement / reduction ratio R to the line width adjustment unit 123. The line width adjustment unit 123 acquires the enlargement / reduction data and the enlargement / reduction ratio R from the enlargement / reduction unit 122. The line width adjustment unit 123 adjusts the line width based on the enlargement / reduction ratio R. The line width Wta used for display is determined based on the following equation as an example, but is not limited thereto.
Wta = Ws / R = Wi (4)
Note that the line width Ws of the scaled character or figure is the line width indicated by the data when the data about the line width is included in the scaled data. Further, the line width adjustment unit 123 may measure the line width Ws from the enlarged / reduced data.

  The line width adjustment unit 123 generates display data in which the line width of the enlarged / reduced data is Wta. Thereby, the size of the character or figure of display data becomes Xo and Yo, and the line width of the character or figure becomes Wta.

FIG. 5C shows characters input to the handwriting input unit 111. Three “a” are drawn with the same line width, but the size of each character is different. The size of the characters decreases from left to right.
FIG. 5D shows characters after enlargement / reduction by the enlargement / reduction unit 122. As shown in FIG. 5C, when “3” is input to the handwriting input unit 111, the three “a” have the same line width but different sizes. Therefore, as shown in FIG. 5D, if each of the three characters is changed to the same size, the line widths are different. Specifically, since the left character and the central character are reduced, the line width becomes narrower. Since the right character is enlarged, the line width becomes thick.
FIG. 5E shows a character whose line width is adjusted based on the present embodiment. The line width of “A” on the left input with large characters does not become thin despite the reduction of the characters. The line width of “A” on the right input with small characters does not become thick, despite the expansion of the characters. The line width of any character is maintained at the input line width regardless of the change in the character size.

Thus, according to the present embodiment, the display unit 130 displays characters or figures. The enlargement / reduction unit 122 changes the size of the character or graphic. The line width adjustment unit 123 maintains the line width of the character or figure before and after the change by the enlargement / reduction unit 122 based on the line width and enlargement / reduction ratio of the character or figure after the change by the enlargement / reduction unit 122.
As a result, the display device 100 can change the size of the character or graphic while displaying the line width of the character or graphic. Therefore, the display device 100 can display the characters and graphics in an easy-to-see manner even when the size of the characters and graphics is changed. For example, when a plurality of characters having different sizes are displayed with the same size, the display device 100 can display the characters with the same line width. In another example, when the size of a character or a figure is reduced, the display device 100 can prevent the line width of the character or the figure from becoming too narrow and reducing the visibility. .

In addition, according to the present embodiment, the line width adjustment unit 123 maintains the line width of the character or figure by dividing the enlargement / reduction ratio with respect to the line width of the character or figure after being changed by the enlargement / reduction unit 122. .
Accordingly, the display device 100 can display characters and figures while maintaining the line width before and after enlargement / reduction even in a situation where the line width of the input characters and figures cannot be known.

(Second Embodiment)
The line width adjustment unit 123b according to the second embodiment adjusts the line width that is maintained before and after the size change based on the coefficient.
The display device 100b according to the present embodiment includes functional units of the display device 100 according to the first embodiment, and a line width adjustment unit 123b instead of the line width adjustment unit 123 of the display device 100. Of the functional units of the display device 100b, the same reference numerals are used for portions corresponding to the respective units of the display device 100 of the first embodiment, and description thereof is omitted.

The line width adjustment unit 123b has a function of calculating the above-described line width Wta (formula (4)), similarly to the line width adjustment unit 123 in the first embodiment. Further, the line width adjustment unit 123b adjusts the line width by using an arbitrary coefficient Kb in addition to the line width Wta. This line width is hereinafter referred to as line width Wtb. The following formula shows an example of the line width Wtb.
Wtb = Wta × Kb (5)

The coefficient Kb is the size Xo and Yo of the character or figure after the size change by the enlargement / reduction unit 122, and the line width Wta calculated by the line width adjustment unit 123b as in the first embodiment (formula (4)). ). For example, when the size after reduction is small, the line width adjustment unit 123b multiplies the line width Wta by a coefficient Kb smaller than 1. Accordingly, the display device 100b can display small characters and figures with a thin line width. Conversely, when the size after enlargement is large, the line width adjustment unit 123b multiplies the line width Wta by a coefficient Kb greater than 1. Thereby, the display device 100b can display a large character or figure with a thick line width.
Note that the line width adjustment unit 123b may set the coefficient Kb opposite to the above example and divide the coefficient Kb.

FIG. 7A shows a rule for setting the coefficient Kb based on the size of the enlarged character or figure and the line width Wta in the present embodiment.
The table t710 is a table in which the size of the character or figure after scaling (item t711), the line width Wta (item t712), and the coefficient Kb (item t713) are associated with each other.
The character size t711 after enlargement / reduction is the product of Xo and Yo. The line width adjustment unit 123b calculates the product of the sizes Xo and Yo of the characters and figures after the change. In addition, the line width adjustment unit 123b calculates the line width Wta (formula (4)) in the same manner as the line width adjustment unit 123 in the first embodiment. The line width adjustment unit 123b refers to the line width adjustment rule t710 and determines the coefficient Kb based on the character size Xo · Yo and the line width Wta. The line width adjustment unit 123b calculates the line width Wtb based on the determined coefficient Kb and the above equation (5). The line width adjustment unit 123b generates display data in which the line width of the scaled data is Wtb.

In the table of FIG. 7A, for example, when the size of the character or figure after the change is 10,000 or more and less than 80,000, and the line width Wta is greater than 10 and less than or equal to 14, The coefficient Kb is set to 0.7. That is, the line width is reduced. Conversely, if the size of the character or figure after the change is greater than 1 million and less than or equal to 2 million in terms of the number of pixels, and the line width Wta is greater than or equal to 5 and less than or equal to 20, the coefficient Kb = 1. That is, the line width is not changed.
Note that the coefficient Kb is not limited to the above example, and various factors may be set in consideration of the visibility and impression of characters and figures.

(Third embodiment)
The line width adjusting unit 123c in the third embodiment adjusts the line width maintained before and after the size change based on the constant.
The display device 100 c according to the present embodiment includes each functional unit of the display device 100 according to the first embodiment, and a line width adjustment unit 123 c instead of the line width adjustment unit 123 of the display device 100. Of the functional units of the display device 100c, portions corresponding to the respective portions of the display device 100 of the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

The line width adjustment unit 123c has a function of calculating the above-described line width Wta (formula (4)), similarly to the line width adjustment unit 123 in the first embodiment. Further, the line width adjusting unit 123c adjusts the line width using an arbitrary constant Kc in addition to the line width Wta. This line width is hereinafter referred to as line width Wtc. The following formula shows an example of the line width Wtc.
Wtc = Wta + Kc (6)

The constant Kc is set based on the enlargement / reduction ratio R input from the enlargement / reduction unit 122 and the line width Wta (formula (4)) calculated by the line width adjustment unit 123c as in the first embodiment. . For example, when the enlargement / reduction ratio R is small, the line width adjustment unit 123c adds a negative constant Kc to the line width Wta. Thereby, the display apparatus 100c can display a character and a figure with a thin line | wire width. Conversely, when the enlargement / reduction ratio is large, the line width adjusting unit 123c adds a positive constant Kc to the line width Wta. Thereby, the display apparatus 100c can display a character and a figure with a thick line | wire width.
The line width adjusting unit 123c may set and subtract the constant Kc opposite to the above example.

FIG. 7B shows a rule for adjusting the line width based on the enlargement / reduction ratio R and the line width Wta in the present embodiment.
The table t720 is a table in which the enlargement / reduction ratio R (item t721), the line width Wta (item t722), and the constant Kc (item t723) are associated with each other.
The line width adjustment unit 123c calculates the line width Wta (formula (4)) in the same manner as the line width adjustment unit 123 in the first embodiment. The line width adjustment unit 123c refers to the table t720 and determines the constant Kc based on the enlargement / reduction ratio R and the line width Wta input from the enlargement / reduction unit 122. The line width adjustment unit 123c calculates the line width Wtc based on the determined constant Kc and the above equation (6). The line width adjustment unit 123c generates display data in which the line width of the enlarged / reduced data is Wtc.

In the table of FIG. 7B, when the enlargement / reduction ratio is 0.1 or more and less than 0.3, and the line width Wta is greater than 10 and less than or equal to 14, the constant Kc = −3. That is, the line width after reduction is reduced. Conversely, when the enlargement / reduction ratio is greater than 3 and less than or equal to 10 and the line width Wta is greater than or equal to 5 and less than or equal to 20, the constant Kc = 0. That is, the line width after enlargement is not changed.
Note that the constant Kc is not limited to the above example, and may be set in various ways in view of the visibility and impression of characters and figures.

FIG. 5F is a diagram conceptually illustrating an example of display of characters and graphics according to the second and third embodiments.
Each of the line width adjustment units 123b and 123c can adjust the line width like the characters in FIG. 5F based on the coefficient Kb and the constant Kc.

  The three embodiments described above can also be used in combination. For example, the line width adjustment unit may combine the second and third embodiments and use an equation including a plurality of coefficients and constants for calculation of the displayed line width. The line width adjustment unit may set coefficients and constants based on other criteria such as a user instruction and the resolution of the display unit 130 as well as the size and enlargement / reduction ratio of characters and graphics.

  Note that a part of the display device in the above-described embodiment, for example, the input size measurement unit, the enlargement / reduction unit, and the line width adjustment unit may be realized by a computer. In that case, the program for realizing the control function may be recorded on a computer-readable recording medium, and the program recorded on the recording medium may be read by a computer system and executed. Note that the “computer system” here is a computer system built in a display device, and includes an OS and hardware such as peripheral devices. The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM and a CD-ROM, and a hard disk incorporated in a computer system.
