DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a function of creating and editing a document, and has a pen-type coordinate detecting device and a pressure detecting device as input means. The present invention relates to an information processing function such as a word processor, a personal computer, an electronic organizer, and a DTP capable of processing pressure data and outputting a processing result to an output unit.

[0002]

2. Description of the Related Art Conventionally, as disclosed in Japanese Patent Application Laid-Open No. 60-157620, a pen-type coordinate detecting device and a pressure detecting device are provided as input means, and coordinate data obtained by the input means are stored in the input means. In an information processing apparatus capable of processing pen pressure data and outputting a processing result to an output unit, the thickness, density, coloring, color, etc. of a drawn line on the coordinates of the output unit are determined according to the sensed coordinate data and the pen pressure data. There has been an information processing apparatus having a function of changing and outputting a shape.

FIG. 15 is an example of a block diagram of the prior art. The input unit 1 is a pen-type input device capable of detecting coordinates and pressure. The data conversion unit 2 converts analog data relating to pen pressure detected by the input unit 1 into digital data. The converted data and a default value relating to the pen pressure stored in the fixed data section 5 are compared by the data processing section 3, and the output information is changed and output to the output section 4 in accordance with the comparison data.

Conventionally, output processing for an input as shown in FIG. 16 has been performed in the configuration of this block diagram. Regardless of the user's pen pressure value, this K point is compared with the pen pressure input by the user with reference to the K point in FIG. 16 fixed as a default value in advance, and if the K point is larger than the reference, output is performed accordingly. A method of outputting a large width (thickness) of a drawn line was adopted.

[0005] However, there is no disclosure of a solution to a problem caused by individual differences between the average value of the writing pressure values and the maximum and minimum values.

[0006]

When the thickness of a drawing line is changed in accordance with the pen pressure, the thickness of the drawing line is not changed even if users having different pen pressures input at normal pen pressures. Every time there is a difference. This is because the user cannot set the reference line thickness, the pen pressure reference data is already fixed as the default value of the information processing device,
This is for performing a process of comparing the value with the pen pressure data input by the user to determine the magnitude of the pen pressure.

FIG. 16 is a graph showing an example of the relationship between the pen pressure of the user input and the change of the drawing line width indicating the change of the output in the prior art. The user uses the pen-type input device to input a line or a figure. In this case, the width (thickness) of the drawing line displayed on the display device increases as the pen pressure value increases.

If the pen pressure at the time of normal input is taken as the average pen pressure and the width of the drawing line output at that time is taken as the average drawing line width, if the users A and B have different pen pressures, the user A , B input differently, but the width of the drawing line is different. Ideally,
Regardless of the variation in the user's pen pressure, when input is performed at normal pen pressure, the output should be at the average stroke width. This is because the conventional technique fixes the average pen pressure data as a default value.

In contrast to the above-described prior art, the present invention makes it possible to set the default value for each user, thereby absorbing variations in pen pressure that differ for each user, and improving the usability of the pen input device. It is an object.

Conventionally, since the pen pressure reference data is already fixed as a default value of the information processing apparatus, there is no function of storing data such as a default value relating to the pen pressure in a storage device or the like.

According to the present invention, data relating to pen pressure and the like is stored in a RAM.
One or a plurality of storage devices such as a hard disk and a floppy disk are stored in the storage device, and the storage device can be called up after the storage, thereby providing a user's desired feeling of use.

(Embodiment 1) FIG. 1 is a block diagram of the present invention.

The input unit 1 has a pen-type input device having coordinate detection and pressure detection functions, and converts detection data such as coordinates and pen pressure obtained by the input unit 1 into digital data through an A / D converter or the like. A data conversion unit 2; a data processing unit 3 for processing the data obtained by the data conversion unit 2 in accordance with an application; an output unit 4 for outputting the data obtained from the data processing unit 3 to a display device or the like; reference writing pressure data unit 7 for a group Junfude圧data <br/> obtained in reference writing pressure setting unit 9 stores in the body to set the pen pressure, the singular this reference writing pressure data in a storage device Alternatively, a pen pressure data storage unit 8 for storing a plurality of units, and a system control unit 6 for controlling a system of each unit.

The X- coordinate data, Y-coordinate data and pen pressure data detected from the input unit 1 are processed by the data processing unit 3 and stored in the main unit memory shown in FIG.

FIG. 2 is a flowchart for setting the reference pen pressure by the user of the present invention.

When the user pen pressure setting function is selected, FIG.
Is displayed, and a predetermined figure is output to the display device (S100).

The figure may be , for example, a crosshair, a circle, a triangle, a square, or the like. When coordinates are detected by the input unit (S10
1) The pen pressure data at that time is read (S102).

If not detected, it waits for detection. The user reads coordinate data by touching the output figure with the input device so as to trace the figure.

When the setting input is started as shown in FIG. 6, the pen pressure data is read in accordance with the sampling clock. The count is incremented to check how many times the data has been read at the same time.

[0023] In addition, After reading the writing pressure data, read the average value + the current to an average value (flat Hitoshifude圧= (previous between the average value and the writing pressure data read now writing pressure data up to the previous pen pressure (Data) / count number) (S103), and repeat until the setting input is completed.

If the end of the setting is selected (S104), the average value of the current pen pressure data is stored in the main body memory shown in FIG. 12 as the reference pen pressure data of the user who made this setting (S105).

FIG. 3 is a flowchart in the case where a drawing line is inputted after the above-mentioned reference pen pressure data is registered.

The following flow is repeated until an end command in the document creation / editing process is selected (S106).

When coordinates are detected by the input unit (S1)
07), and stores the coordinate data in the memory (S10).
8) Then, the pen pressure data is also stored in the memory (S10).
9).

The registered reference pen pressure data and the currently read pen pressure data are compared numerically (S110).

In proportion to the comparison result, for example, if the pressure data just read is N times larger than the reference pen pressure data, the data of the drawing line which is N times thicker than the drawing line at the time of the reference pen pressure data is calculated (for example, drawn line data = read writing pressure data / reference writing pressure data × (maximum drawn line width - minimum drawn line width) / 2), and stored in the memory (S 111).

Then, a drawing line is output at the designated coordinate position of the display device with the thickness stored in the memory (S11).
2).

FIG. 4 is a graph showing a change in the width of the output drawing line with respect to the input pen pressure data when the first embodiment is performed.

Assuming that the average pen pressure is the case where the users A and B having different pen pressures input at the same normal pen pressure, the width of the drawing line at the average pen pressure differs in the conventional method. However, in the present invention, the average pen pressures of the users A and B are registered, and the average drawing line is always output at the average pen pressure.

Embodiment 2 FIG. 1 is a block diagram of the present invention, and details are the same as those in Embodiment 1.

The X- coordinate data, Y-coordinate data, and pen pressure data detected from the input unit 1 are processed by the data processing unit 3 and stored in the main unit memory shown in FIG.

FIG. 7 is a flowchart for setting the reference pen pressure by the user according to the present invention.

When the user pen pressure setting function is selected, FIG.
Is displayed, and a screen for inputting the maximum value and the minimum value of the pen pressure by the user is displayed (S2).
00).

The method of inputting the maximum and minimum values of the pen pressure is, for example, as shown in FIG. There is a method of applying pressure to the input device with the pen pressure considered to be the minimum.

When the coordinate data is read from the input unit (S201), the pen pressure data at that time is read by the input unit (S202).

If the coordinate data is within the maximum input range of the pen pressure (S203), the pen pressure data is stored in the address nn03 (pen pressure setting maximum value data) in the main body memory having the configuration shown in FIG. (S204).

However, if the coordinate data is within the minimum pen pressure input range (S205), the pen pressure data is stored at address nn04 (pen pressure setting minimum value data) in the main memory having the configuration shown in FIG. S206).

When the end of the pen pressure setting is selected (S20)
7) Calculate the input / output inclination from the maximum and minimum pen pressures (for example, input / output inclination = (maximum drawing line width-minimum drawing line width) / (maximum pen pressure value-minimum pen pressure value)) Then, it is stored in the main body memory (S208).

[0042] Finally, calculate the mean value from the maximum value and the minimum value of the writing pressure (e.g., average value = (maximum brush pressure value - minimum brush pressure value) / 2) to the memory as a reference writing pressure data The setting is stored (S209) , and the setting ends.

FIG. 3 is a flowchart in the case where a drawing line is input after the reference pen pressure data is registered, and the operation is the same as that of the first embodiment.

FIG. 8 is a graph showing a change in the width of the output drawing line with respect to the input pen pressure data when the second embodiment is performed.

Assuming that the average pen pressure is the case where the users A and B having different pen pressures input at the same normal pen pressure, the width of the drawing line at the average pen pressure differs in the conventional method. .

Further, since the rate of change of the drawing line width with respect to the pen pressure is fixed, for example, when a user with relatively high pen pressure performs an input, the maximum drawing line width is obtained despite the normal input. The drawing line width is close to, and if you increase the pen pressure slightly, the drawing line width will be maximum, or conversely, to enter a thin line close to the minimum drawing line width, you need to reduce the pen pressure considerably. In some cases, input becomes difficult.

However, in the present invention, the maximum value and the minimum value of the user's pen pressure are registered, and the relation between the input pen pressure value and the output drawing line width is treated functionally (for example, output drawing line width data = input / output of input / output). With the inclination data x the input pen pressure data), the maximum stroke width is output at the maximum pen pressure of each user, and the minimum stroke width is output at the minimum pen pressure. The size changes and is output.

The first and second embodiments have a pen-type coordinate detecting device and a pressure detecting device, and are capable of obtaining coordinate data and pen pressure data. A registration means for registering as pen pressure data, a comparison processing means for comparing the data obtained by the input means with the reference pen pressure data registered by the registration means, and a processing means for determining the thickness of the drawing line to be output, and an input means for obtaining This is realized by an information processing device constituting these, such as output means for outputting a drawing line at coordinates based on the coordinate data obtained.

The registration means registers the user's own normal pen pressure previously input by the input means as reference pen pressure data. After the registration, the pen pressure data sensed at the time of pen input is registered by the comparison processing means at any time. The pen pressure data is compared with the reference pen pressure data, and the thickness of the drawing line output to the output unit is changed in accordance with the difference, thereby absorbing a variation in pen pressure that differs for each user.
