Abstract

PROBLEM TO BE SOLVED: To intuitively recognize the mode of editing and the kind of plotting corresponding to current pen pressure by plotting a cursor with a color, density, and lightness corresponding to the pen pressure at the position corresponding to coordinates detected by a coordinate detecting means. SOLUTION: The coordinate detecting means 1 detects coordinate values instructed by a user and a pen pressure detecting means 2 detects pressure (pen pressure value) that the user uses at the time. A pen pressure fixing means 6 and a fixation releasing means 7 fixes the pen pressure value and resets the fixation state according to respective specific conditions. In the fixation state, a character and graphic plotting means 5 plots characters and graphics with the thickness, color, density, lightness, etc., corresponding to the fixed pen pressure value at the position corresponding to the detected coordinates. When the fixation state is reset, the characters and graphics are plotted with the size, color, density, lightness, etc., corresponding to the detected pen pressure value at the position corresponding to the detected coordinates.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus capable of inputting and editing documents and images by pen operation in a word processor, a personal computer or the like having a coordinate input device capable of detecting writing pressure such as a pen input device. It is about.

[0002]

2. Description of the Related Art In recent years, it has become possible to draw and edit characters and images on a word processor or personal computer by operating a pen, and to provide intuitive and easy operability with a pen. However, few of these pen input interfaces are sensitive to pen pressure, and few are effectively utilizing it. In order to deal with such a current situation, the conventional technology presents a method of changing the width of a line or a size of a point to be drawn according to the magnitude of the writing pressure and a method of selecting an object to be edited according to the magnitude of the writing pressure. What has been done exists. The writing pressure and the line width are in a proportional relationship. Therefore, by drawing the line while changing the writing pressure, it is possible to draw a line having a changing line width.

The technique disclosed in Japanese Patent Laid-Open No. 4-279980 proposes a method of selecting a plurality of overlapping objects or windows according to the magnitude of the writing pressure detected by the writing pressure detection device. Also, regarding the drawing of the image, by controlling the transmittance of the drawn color according to the magnitude of the writing pressure, the mixing ratio of the underlying color and the drawn color is adjusted, and the watercolor of the actual paintbrush It is designed so that you can get a natural sensation close to overpainting. In addition, the technique disclosed in Japanese Patent Laid-Open No. 5-282094 detects the magnitude of the writing pressure and changes the width of the line or the size of the point according to the magnitude of the writing pressure so that the human actually A handwriting input device that is close to the feeling of drawing is presented.

Furthermore, the technique described in Japanese Patent Laid-Open No. 195938/1983 proposes a method of inputting spread information according to the writing pressure. In this example, it is stated that pressure can be applied to the light pen while looking at the screen on the CRT so that it locks at the desired expansion, and that a circle can be drawn by specifying the compass and radius and center position. There is. In other words, set the thickness of the drawn line according to the pressure,
A circle or the like can be drawn with the drawn line of that thickness. However, it does not describe the means for locking at the desired spread.

[0005]

In the information processing apparatus as disclosed in the above publications, the line width to be drawn is changed depending on the detected writing pressure, or the color to be drawn is changed depending on the writing pressure. With the technique of changing the transmittance,
Since there is no means for immediately confirming the magnitude of the writing pressure applied to the pen by the user, the only way to adjust the writing pressure is to rely on the human sense of the hand, and to check the strength of the writing pressure. The only way to check was by moving the pen to draw a line, and then making a judgment based on the thickness of the line. Also,
If you do not want to change the above-mentioned transmittance or line width depending on the size of the writing pressure, you need to perform an operation to switch between the mode that detects the writing pressure and the mode that does not detect it. It is necessary to separate the position of the pen from the current position and select with a menu or icon, which is troublesome to operate.

In the technique disclosed in Japanese Patent Laid-Open No. 58-195938, it is possible to arbitrarily change the line width of a drawing line, lock it at a desired position, and draw a figure with the locked constant line width. Yes, but no means for locking is mentioned. If a lock instruction key is installed on the keyboard as an easily conceivable method, it is necessary to push down the key of the keyboard with the hand opposite to the hand holding the pen, and both hands must be used, resulting in poor operability. In addition, the method of providing a switch for that purpose on the pen has a problem that it causes a cost increase.

In order to solve the above problems, the present invention changes the shape, size, color, etc. of the pen cursor according to the pen pressure, and the user recognizes the shape to change the mode of editing under the current pen pressure. The purpose is to be able to intuitively recognize the type of drawing. Further, in the present invention,
Detecting changes in the pen pressure applied to the pen and responding to the changes in line width and edit mode, etc. is suitable for different situations (mode change)
The purpose is to make it possible by a simple pen operation.

Further, in the present invention, it is used that the mode in which the line width, the edit mode, etc. are changed in response to the change in the pen pressure applied to the pen and the mode in which it is not changed is switched. The purpose is to make it easy for the person to recognize. Further, according to the present invention, the user can easily set the condition for detecting the change in the pen pressure applied to the pen and switching between the mode in which the line width, the edit mode and the like change and the mode in which it does not. It is intended to be possible.

FIG. 2 is a system configuration diagram showing an embodiment of the present invention. Reference numeral 21 is a pen input device including a coordinate detection device 21a and a writing pressure detection device 21b. By bringing the pen 21c into contact with the tablet 21d, the coordinates and writing pressure (the pen 21c is moved to the tablet 21d).
Pressure) is detected. Reference numeral 22 denotes a central processing unit, which executes programs stored in the RAM 28 and the ROM 29 described below and performs various processes on devices and devices connected to the CPU bus. For example, the pen input device 21
Drawing data is written to a specific address on the following V-RAM 23 based on the information obtained from the above. Reference numeral 23 is a RAM that holds the image image displayed on the display 24. By writing drawing data in the RAM 28 described below, the drawing content is reflected on the display. Reference numeral 25 denotes a disk control device, which controls reading / writing of data from / to a storage device 26 such as a hard disk or a floppy disk described below.

Further, the storage device 26 stores a program, data controlled by the program, and the like, and can be stored for a long term. The keyboard 27 is a device for inputting keys, and detects information on the pressed keys. The RAM 28 is a readable / writable memory, and the ROM 29 is a read-only memory, both of which hold programs and data, and the CPU 22 directly controls the programs and data held therein. Reference numeral 30 denotes a timer control device that manages time, and by starting this device, it is possible to measure the time from one instant to the next. A sound output device 30 controls the speaker 31 to emit a sound.

FIG. 3 shows the overall flow of this apparatus. Routine in this flowchart, the user pen event is started every time that occurs by manipulating the pen 21c (Step S _1). What is a pen event? When the pen 21c touches the tablet 21d (pen down), the pen 21c remains touching the tablet 21d (pen drag), and the pen 21c is released from the tablet 21d (pen up). This is an event that occurs.

Further, an event occurs at the moment when the pen 21c is touched on the tablet 21d in the pen down mode, at a short interval during dragging with the pen drag (order of several milliseconds), and at the moment when the pen 21c moves away from the tablet 21d in the pen up mode. Occurs. In this flowchart,
First, the coordinates and the pen pressure value when a pen event occurs are substituted into variables (steps S ₂ and S ₃ ). The coordinates and the writing pressure value are values obtained by being digitized by the coordinate detection device 21a and the writing pressure detection device 21b.

The variables (X, Y) are secured in the RAM 28. The variables and flags shown in the following examples are also the same. Next, it is judged whether the fixed state flag is ON or not (step S ₄ ), so that the process is changed to the drawing / editing variable process (step S ₅ ) or the drawing / editing fixed process (step S ₆ ).
Branch to The fixed state flag is a flag that indicates whether the current drawing or editing state of the pen 21c is changed by a pen pressure, which will be described later, or is fixed regardless of a change in the pen pressure. Drawing / Editing Variable processing and drawing
The processing content of the edit fixing processing will be described in detail in an example described later. When the drawing and editing process is completed the current coordinates and writing pressure value of the variable (X ', Y') to exit and save the P '(step S _7, S _8).

FIG. 4 is a flowchart of a routine for drawing a cursor in claims 1, 2, and 6. This routine is called from the drawing and editing variable processing (step S _5), or drawing and editing fixation treatment (Step S _6), pen pressure value of the coordinate is passed as an argument when called. In this routine, first, the arguments are substituted into p and (x, y), respectively (step S ₁₁ ). Then p
The cursor is selected according to the size of and the bit map image is developed in the work area W prepared on the RAM 28 (step S ₁₂ ).

In claim 1, for example, as shown in FIG. 5A, the writing pressure p is 0 <p < P ₁ , P ₁ <p < P ₂ , P ₂ <p <
P _MAX (P _MAX is the maximum value of the writing pressure) is divided, and the cursor 1, the cursor 2, and the cursor 3 are associated with the writing pressure in each range. For each cursor, prepare such that the user can see the cursor and immediately know what the current drawing and editing mode is. For example, when the width of the drawn line changes depending on the writing pressure, the thickness of the pen tip such as a pencil, marker, or brush of paint is different so that the drawn thickness can be seen as shown in FIG. 5B. Prepare something like this. The cursor resources are the RAM 28, the ROM 29, or the storage device 26.
The cursor is stored in one of the two, and the cursor to be displayed is selected by the writing pressure p from the stored data, and the cursor is expanded to the work area on the RAM 28.

In the second aspect, as shown in FIG.
And the writing pressure p have a relation such as α = p / P _MAX (0 < p < P _MAX ), and the α is used to change the shade of color, the brightness, and the degree of color mixture. In this example, a case will be described in which the color changes from white to red as the writing pressure value p increases, as shown in FIG. 6B, for example. When the color when the writing pressure is 0 is C ₁ and the color when the writing pressure is increased to P _MAX is defined as C ₂ , the color C to be colored on the cursor is C = (1-α) C ₁ + αC _Expressed as ₂ . In step S ₁₂ the color C, RAM
Color on the cursor that is expanded above. Here, the color C is represented as a vector having independent parameters, but it does not particularly mention what component (for example, each component of RGB) the parameter is.
In addition, when changing the shade of color or brightness,
Can be represented.

After selecting the bitmap image of the cursor by using claim 1 or claim 2 as described above, the fixed state flag is referred to (step S ₁₃ ), and if the flag is on, further patterning is performed. Or an icon is added to W (hereinafter, the state in which a pattern, an icon, or the like is added to the cursor is referred to as the cursor being locked). This allows
According to the sixth aspect, it is possible to distinguish a cursor having the same shape when drawing or editing is in a fixed state and when the fixed state is released. The fixed state flag is turned on or off when a specific condition is satisfied in the flowchart of the drawing / editing variable process (step S ₅ ) and the drawing / editing fixed process (step S ₆ ) described later. For example, in FIG. 7A, the fixed state flag is turned on and the cursor is locked because the variable drawing / editing process satisfies the condition of claim 4, and in FIG. 7B, the drawing / editing variable process is performed.
This shows that the fixed state flag is turned off because the edit fixed process satisfies the condition of claim 10 and the locked state of the cursor is released.

The processing from step S ₁₅ onward shows the procedure for transferring data to the V-RAM 23 in order to draw the cursor. First, before the cursor bitmap data W is transferred to the address on the V-RAM 23 corresponding to the coordinates (x, y) (step S ₁₉ ), the cursor previously displayed in this routine is erased, so that it is already saved. 'the (x' bitmap data W are the, y ') to transfer (step S _16). In addition, if there is no save data to W '(when the display cursor is the first of this time) is to skip this (step S _15). W 'at step S _19, W
Was saved bitmap display area fraction of W from the top V-RAM 23 before forwarding on to the V-RAM 23 from the (x, y) (step S ₁₇₎ are those, (x ', y') is (x , Y) is saved (step S ₁₈ ).
Both are the bitmap and coordinates of the cursor that was previously displayed by this routine.

Next, the drawing / editing variable processing (step S ₅ ) and the drawing / editing / fixing processing (step S ₆ ) mentioned above will be described. The former is a process in which the drawing type and the editing mode are changed according to the magnitude of the writing pressure, and the latter is a process in which the drawing type and the editing mode are fixed regardless of the change in the writing pressure. 8 and 9 show the former flow.
Is an example of claim 4, and FIG. 9 is an example of claim 5. Figure 10,
FIG. 11, FIG. 12 and FIG. 13 show the latter flow, and FIG.
Is an example of claim 7, FIG. 11 is an example of claim 9, FIG. 12 is an example of claim 9, and FIG. 13 is an example of claim 10.

In FIG. 8, as shown in the graph of FIG. 14 (a), since the time measurement is started, T _MAX time, the amount of change in writing pressure is within ΔP from P ₀ , and the amount of change in coordinates is. When it is within ΔL from X ₀ and Y _{0 in the} X direction and the Y direction, respectively, when T _MAX is exceeded, the writing pressure is P ₀ and the coordinate is (X ₀ , Y ₀ ).
Shows a flow for switching to a fixed state (the drawing type and the editing mode are constant regardless of the writing pressure). The condition for starting the time measurement is the previous coordinates (X ', Y')
And writing pressure P '(coordinates and writing pressure values saved when the routine of FIG. 3 is called when a pen event occurs and is called), when both steps S ₂₂ and S ₂₃ are satisfied. Here, the max in step S ₂₁ {X, Y}, a representation method that takes the maximum value of X and Y.

Therefore, in step S ₂₂ , it is judged whether both the amount of change of X with respect to X ₀ and the amount of change of Y with respect to Y ₀ are equal to or less than ΔL. In Step S ₂₇ and S ₂₈ If this condition is not satisfied, the drawing cursor drawing process,
Perform edit processing and exit. The former passes (X, Y) and P as arguments to the above-mentioned routine of FIG. 4, and draws a cursor corresponding to the coordinates and the writing pressure. The latter uses the same arguments as the former to perform drawing processing and editing processing corresponding to the coordinates and the writing pressure (for example, changing the line width according to the magnitude of the writing pressure).

However, in the present invention, since the processing contents of drawing and editing are not important, a specific example will not be described. If both conditions in steps S ₂₂ and S ₂₃ are satisfied, the timer is turned on in step S ₂₄ and the coordinates and writing pressure at that time are substituted into (X ₀ , Y ₀ ) and P ₀ , respectively, and steps S ₂₅ and S _26. , Steps S ₂₇ and S ₂₈ are processed and terminated.
Here, turning on the timer starts time measurement. When this routine is called next time, since the timer has already been turned on, the processing from step _S36 onward will be performed. If the elapsed time from turning on the timer in step S ₃₇ is equal to or less than T _max , the current coordinates and the writing pressure change with respect to the coordinates (X ₀ , Y ₀ ) at the start of time measurement and the writing pressure P ₀ . Compare whether the quantity meets steps S ₃₀ and S ₃₁ . If both are satisfied, steps _S33 and _S34
Process and exit.

In steps S ₃₃ and S ₃₄ , (X ₀ , Y ₀ ) and P ₀ are passed as arguments, and cursor drawing processing and drawing /
Although the editing process is being performed, if this is within T _max time and the conditions of steps S ₃₀ and S ₃₁ are satisfied, the user does not change the shape of the cursor or the like to allow the user to operate the pen. This is so that it is possible to visually judge whether or not the coordinates and the writing pressure are equal to or less than a predetermined change amount when performing.
If the condition is not satisfied in step S ₃₀ or S _31, turns off the timer and exit processing steps S ₂₇ and S _28.
By turning off the timer Here, it will be the processing after step S ₂₁ is when the routine is called in the next time.

In FIG. 9, as shown in the graph of FIG. 15, when the coordinate change amount is L _max , the writing pressure change amount is within ΔP from P ₀ , and when the coordinate change amount exceeds L _max. Pen pressure to P ₀
Shows a flow for switching to the fixed state. Conditions for starting the measurement of the coordinates of the amount of change If the condition is satisfied in step S ₅₁ as compared to the previous P '(Step S ₈₎ (that is, the current of the brush pressure value with respect to the previous pen pressure value of The change amount is within ΔP). If this condition is not satisfied and exit processing steps S ₅₅ and S _56, but if corresponding to this condition by turning on the pen pressure constant flag, each current coordinates and writing pressure of (X _0, Y ₀ ) and P ₀ (steps S ₅₃ and S ₅₄ ), and steps S ₅₅ and S ₅₆ are processed and the process ends. At this time, when this routine is called next time, the writing pressure constant flag is turned on, so that the processing in and after step S ₆₂ is processed.

In step S ₆₃ , it is determined whether the amount of change in coordinates from (X ₀ , Y ₀ ) exceeds L _max. If not, it is compared whether the amount of change in writing pressure with respect to P ₀ is within ΔP. (Step S ₅₈ ), and if this condition is satisfied, steps S ₅₉ and S ₆₀ are processed and the process ends. Here, P ₀ is passed as an argument because the shape of the cursor is not changed while the amount of change in coordinates is within L _max and the condition of step S ₅₈ is satisfied.
This is for the user to visually judge that the amount of change in writing pressure is less than or equal to a predetermined amount during pen operation during this period.

If the condition of step S ₅₈ is not satisfied, the amount of change in writing pressure exceeds a predetermined amount, so the writing pressure constant flag is turned off (step S ₅₇ ), and steps S ₅₅ and S ₅₆ are processed and terminated. . In step S ₆₃ , the coordinate change amount is ΔL
If it exceeds, the fixed state flag is turned on (step S ₆₄ ).
Then, after substituting the writing pressure value P ₀ at the measurement start time into P _fix , the processes in and after step S ₆₆ are finished. The fixed state flag and P _fix are as described in the description of FIG.

FIG. 10 shows a flow for releasing the fixed state when the writing pressure becomes 0 as shown in the graph of FIG. In step S _72, when the pen pressure value of 0 or less (pen 21c is away from the tablet 21d) ends the fixed state flag OFF (S ₇₁₎ to. When the fixed state flag is off, when the pen event occurs next time and the routine of FIG. 3 is called, the drawing / editing variable process (step S ₅ ) is processed and the drawing type and the editing mode are the pen pressure. The process shifts depending on the size.
Further, when the fixed state flag is turned off,
Patterns and icons on the appended which was cursor is erased to in the fixed state in the routine (step S _3).
In step S _72, when the pen pressure is greater than 0 performs the processing of steps S ₇₃ and S ₇₄ at the writing pressure P _fix. This P
_{The fix} is a value that has no relation to the magnitude of the writing pressure currently applied by the user, and is the value set when switching to the fixed state in FIG. 8 or 9 described above, or set by another means. This is the value that was set.

In FIG. 11, when the writing pressure does not become larger than 0 for T _max time after the writing pressure becomes 0 as shown in the graph of FIG. 17, the fixed state is released in the subsequent pen processing. Shows the flow for. Step S
_{In 83} , when the writing pressure value is 0 or less, the timer is turned on (step S ₈₂ ) and the time measurement is started. Step S
_{At 81, it is} already determined whether the timer is on, and if the timer is on, step _S82 is skipped. This is a countermeasure when a pen event occurs when the pen is separated from the tablet. Is. If stylus pressure is greater than 0 in step S _83, the timer is judged whether it is turned on, if the timer is not turned on, the process of step S ₉₂ and S ₉₃ at a fixed writing pressure P _fix Do.

If the timer is already turned on in step S ₈₄ , the elapsed time from the start of time measurement is T
_If it is compared with _max (step S ₈₆ ), and the elapsed time is within T _max (that is, the time until the pen 21c is lifted up from the tablet 21d and lowered again on the tablet 21d does not exceed the predetermined time), the timer Is turned off (step S ₉₁ ), the processes of steps S ₉₂ and S ₉₃ (fixed writing pressure process) are performed, and the process ends. If the elapsed time in step S ₈₆ exceeds T _max (i.e., when the time of the pen 21c until down from the up from the tablet 21d exceeds a predetermined time), the fixed state flag is turned off (step S ₈₇₎ Then, the processes from step S ₈₇ are performed. The fixed state flag P _fix is the same as that described with reference to FIG.

In FIG. 12, as shown in the graph of FIG. 18, after the time measurement is started, T _max , the writing pressure change amount is within ΔP from P ₀ , and the coordinate change amount is X ₀ . Y ₀
From ΔL in the X and Y directions respectively,
A flow for releasing the fixed state when T _max is exceeded is shown. Since the condition for releasing the fixed state is the same as the condition for switching to the fixed state in FIG.
The location where the condition is judged in 2 is the same as the relevant location in FIG. Therefore, in FIG. 12, only the points different from FIG. 8 will be described. In FIG. 12, drawing and editing are performed as cursor drawing and the like irrespective of the magnitude of the writing pressure, and therefore, they are passed as the P _fix argument as in steps S ₁₀₇ , S ₁₀₈ , S ₁₁₃ , and S ₁₁₄ . P _fix is the same as the description described with reference to FIG. In step S ₁₁₈ , the fixed state flag is turned off when the above condition is satisfied. This fixed state flag is also as described in the description of FIG.

In FIG. 13, as shown in the graph of FIG. 19A, the amount of change in writing pressure becomes P _max or more by the time ΔT from the start of time measurement, and the change in coordinates up to that point. A flow for releasing the fixed state when the amount is within ΔT is shown. The conditions for starting time measurement are
This is a case where the amount of change from the previous coordinate satisfies the condition of step S ₁₃₂ (the amount of change of the coordinate with respect to the previous coordinate is within ΔL), and when the condition is satisfied, the timer is turned on (step S ₁₃₃ ) and step S _{134 is performed.} Perform the following processing.

If the condition in step S ₁₃₂ is not satisfied, the processing in step S _{116 and the} subsequent steps is ended. In steps S ₁₃₆ and S ₁₃₇ , the processing is performed with a fixed writing pressure value P _fix irrelevant to the writing pressure applied to the pen. Figure 1 for P _fix
0 is as described. The timer was turned on when this routine was called (time measurement has started)
If the elapsed time is performed to determine whether conditions are satisfied in step S _141, if this condition is satisfied, the timer off for the predetermined time has elapsed (step ₁₃₈₎
Then, the processes of steps S ₁₃₆ and S ₁₃₇ are performed and the process ends.

[0053] If in step S ₁₄₁ is within the predetermined time, the amount of change in coordinate from the time of starting the time measurement it is determined whether conditions are satisfied or step S _144. Here, by giving the value of P _max close to the maximum possible writing pressure value, it is possible to narrow down the pen operation to satisfy this condition to some extent. For example, when the maximum value that the writing pressure value can take is P _MAX , in order to satisfy the condition of step S ₁₄₄ , P ₀ < P _MAX − is obtained from P _MAX −P ₀ > P _max.
If P _max is reached and P ₀ is not close to 0, then step S ₁₄₄
Can not meet. That is, in the pen operation of the user, it is necessary to temporarily lower the writing pressure to near 0, and then raise the writing pressure to a value close to the maximum value or less within a predetermined time within a predetermined time.

As described above, the possibility that the fixed state is unintentionally released during the drawing / editing process of the fixed state is reduced. If the condition is satisfied in step _S144 , the fixed state flag is turned off (step ₁₄₇ ) and the processes in step _{148 and} thereafter are performed. In steps S ₁₂₉ and S ₁₃₀ , since the fixed state of the writing pressure is released at that point, P _{fix is set} as an argument.
P is passed instead of. If the condition is not satisfied in step _S144, it is in the process of detecting whether or not the condition for releasing the fixed state is satisfied, and therefore the coordinates between them are fixed to the values at the time measurement start point (step S
₁₄₅ , S ₁₄₆ ), and care is taken so that during the operation, drawing and editing processes are not applied to changes in coordinates. Further, in step S ₃₈ or step S ₃₄ , the user can be informed of the change to the fixed state by emitting a beep sound or the like through the sound output device 31, and steps S ₇₁ , S ₈₇ , S _{118. Alternatively} , in S147, the user can be notified of the change from the fixed state to the released state by a beep sound or the like.

Furthermore, by securing ΔL, ΔP and T _max in FIG. 8 as variables on the RAM and substituting the numerical values input from the input devices 21 and 27 into these variables,
It is possible to arbitrarily secure the conditions for switching to the fixed state. The same applies to ΔP and L _max in FIG. 9, and the conditions for releasing the fixed state in the same manner for T _max in FIG. 11, ΔL, ΔP and T _max in FIG. 12, and ΔL, ΔT and P _max in FIG. Can be set.
