Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handwriting input device for inputting data by handwriting input, and more particularly to a handwriting input device for editing image data by designating a region on a screen by handwriting input of a graphic image.

[0002]

2. Description of the Related Art Recently, the importance of user interfaces in computers has been recognized. Along with this, GUI (Graphical User Interfac
e; Graphical user interface) is becoming the mainstream of user interface.

In this interface, by selecting an icon (pictorial symbol) by operating a mouse or a keyboard, it is possible to perform all operations other than character input such as command selection, file operation, and program start-up from a menu. It has become.

[0004]

However, since the conventional GUI is based on mouse operation, there is a problem in terms of operability. That is, the movement of the mouse cursor for selecting an icon by operating the mouse is not so smooth, and it takes a long time even if the user gets used to it. Also, a space for operating the mouse was required. Recently, pen input has been attracting attention as a means for overcoming the drawbacks of the mouse as a pointing device.

The pen input allows the user to directly input characters, figures and the like on the display surface in the same manner as when writing in a notebook or notebook that the user is accustomed to. Moreover, since the selection of an icon can be pointed out directly with a pen, it is very easy and fast, and it is suitable as a pointing device for GUI.

Therefore, if it becomes possible to perform editing such as deletion of data on the screen or conversion of typeface on the screen, which was conventionally performed by key operation or mouse operation, by handwriting input by pen operation, the editing work becomes easy and efficiency is increased. It is expected to improve. In addition, it is considered that the work can be performed with a natural feeling without a sense of discomfort unlike in the past.

SUMMARY OF THE INVENTION It is an object of the present invention to make it possible to easily and quickly edit image data that has already been input by handwriting input with a pen in a handwriting input device that uses pen input as a basic operation.

[0008]

The present invention comprises the following means. The display means is a device that displays image data in a bitmap format, and is composed of, for example, a liquid crystal display device.

The coordinate detecting means detects the coordinates of the operation position of the pen on the display screen of the display means. This means is composed of, for example, a pressure sensitive type, a capacitance type, an electromagnetic induction type tablet (digitizer).

The image recognition means recognizes the input of a graphic image for area designation based on the coordinate data of the operation position of the pen detected by the coordinate detection means. The area setting means
The edit target area on the screen displayed on the display means is set based on the coordinate data of the entry position of the graphic image for area designation recognized by the image recognition means.

The command recognition means recognizes the input of a previously reserved editing command based on the coordinate data of the pen operation position detected by the coordinate detection means after the area to be edited is set by the area setting means. .

The editing means performs the editing specified by the editing command recognized by the command recognizing means on the image data in the editing target area set by the area setting means.

The registration means, after the editing by the editing means is completed,
The edit command recognized by the command recognition means is registered. Then, when the image recognition means recognizes the input of a new graphic image for area designation after the registration means has registered an arbitrary edit command, the editing means uses the area setting means based on the graphic image. The image data in the set editing target area is edited by the editing command registered by the registration means.

The registration means, the image recognition means, and the editing means may be configured as described in claim 2, for example. That is, the registration means registers the arbitrarily input graphic image for designating the area and the pre-reserved edit command input corresponding to the graphic image.

Further, the image recognition means recognizes a new input of a graphic image for area designation similar to any of the graphic images registered by the registration means. The editing means recognizes the graphic image recognized by the image recognizing means with respect to the image data in the edit target area newly set by the area setting means based on the newly input graphic image for specifying the area. Editing is instructed by the editing command registered corresponding to.

The above image recognition means, area setting means,
The command recognition means, the editing means, and the registration means are composed of, for example, a CPU (central processing unit), a memory, a subsystem dedicated to image data processing, and the like.

[0017]

In the present invention, when the user hand-writes an arbitrary graphic image for designating the area by pen operation on the screen displayed on the display means, the coordinate detecting means detects the coordinates on the screen of the entry position. To detect. The image recognition means receives the detected coordinate data of the handwriting input from the coordinate detection means, and recognizes that the graphic image for area designation is handwritten based on the coordinate data. Then, the area setting means sets an edit target area on the display screen of the display means based on the recognized position data of the figure image, based on the recognized position data of the figure image.

As a result, the edit target area on the screen is set by the handwritten input graphic image for designating the area. Subsequently, when the user manually inputs a reserved editing command by pen operation, the editing command is recognized by the command recognizing means, and the editing means edits the editing specified by the recognized editing command as the above-mentioned editing target. Perform on the image data in the area. And
After that, the editing command is registered by the registration means.

Next, when the user manually inputs a graphic image for designating a new area by operating the pen, the image recognition means recognizes the input of this graphic image. The area setting means sets a new area to be edited in the same manner as above in response to the input of this graphic image. Then, the editing means performs editing specified on the image data in the editing target area by the editing command registered by the registration means as described above.

Therefore, once the user operates the pen to input the figure image for area designation and the edit command by handwriting to execute predetermined editing, the next step is to input only the figure image for area designation. Thus, the same editing work as the previously executed editing can be performed at high speed on the image data designated by this graphic image.

In the above operation, the registration means is, for example,
When the user performs handwriting input of an arbitrary graphic image for specifying an area and an edit command reserved in advance by a pen operation, the input graphic image and the edit command are registered in association with each other. Then, when a new graphic image is input thereafter, the image recognition means recognizes the input of this graphic image, and the area setting means sets the edit target area based on the entry position of this graphic image.
Then, the editing means searches the image data in the newly set editing target area for a graphic image most similar to the newly input graphic image among the graphic images already registered. Then, the editing indicated by the editing command registered corresponding to the graphic image is performed.

Therefore, it is possible to register an editing command reserved in advance for each of a plurality of types of graphic images. After the registration, the desired editing operation can be performed at high speed simply by entering a graphic image similar to the registered graphic image in association with the desired edit command.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an external view of an embodiment of the present invention.

The apparatus shown in the figure has a basic operation of handwriting input with the pen 11 and has a handwritten character recognition function. The entire device has a pad type outer shape, and a pen storage groove 12 for storing a pen 11 is provided above the device. Further, an input / display device 13 for pen input is incorporated in almost the entire upper surface except the pen housing groove 12.

The input / display device 13 is composed of a display unit 13a composed of a bit map display such as a liquid crystal display and a coordinate input unit 13b composed of a tablet arranged so as to overlap with the display unit 13a.

Next, FIG. 2 shows a system configuration of an embodiment having the above appearance. In the figure, a CPU 21 is a central processing unit such as a microprocessor, and executes a program stored in a program memory 22 to control each component in the system.

The coordinate input unit 13b is composed of, for example, a pressure-sensitive tablet, an electromagnetic induction tablet or the like, and when a pen input is detected, the coordinate position of this pen input (coordinate data of the handwriting input writing locus) is passed through an interface (not shown). CP
Output to U21. The CPU 21 generates handwritten image data by pen input from this coordinate data and writes it in the image memory I26.

The image recognition section 23 receives the instruction from the CPU 21 and recognizes the handwritten input data as a graphic. Then, based on the handwritten input coordinate data, it is checked whether or not the recognized figure is a figure image (hereinafter referred to as an enclosing figure) designating an area having a certain size or more, and the enclosing figure is checked. Recognize handwriting input. Then, these recognition results are returned to the CPU 21.

In response to the recognition result, if the enclosing figure is input, the CPU 21 determines the area on the display screen enclosed by the enclosing figure as the edit target area from the handwritten input coordinate data of the enclosing figure. Set. Also,
Further, the edit command memory 36 is referred to check whether or not the edit command is already registered. Then, if registered, the edit command is executed for the image data in the edit target area.

The command recognition unit 24 receives the instruction from the CPU 21 and recognizes the handwritten input data as characters. The character string (or symbol) obtained by this character recognition is collated with the character string (or symbol) of the edit command stored in the reserved command memory 25 to recognize the handwriting input of the edit command. Then, the recognition result is returned to the CPU 21.

When the CPU 21 knows the input of the edit command based on the recognition result and recognizes that the enclosing graphic has been input before the input of the edit command, the CPU 21 outputs this edit command in the future. It is stored in a predetermined area of the edit command memory 36 as an edit command specified by the input enclosing figure. Then, the editing specified by this editing command is executed on the image data in the editing target area set by the surrounding figure.

The reservation command memory 25 stores text data or symbol data (character code string or symbol) for all editing commands usable in this apparatus as shown in FIG. 3, FIG. 5, FIG. 7 and FIG. It is stored in the format of (code string).

The edit command memory 36 stores the above-mentioned edit commands inputted after enclosing figures of various shapes. The image memory I26 is a memory for storing the latest handwritten input image data pen-input on the screen of the input / display device 13 in a bitmap format.

The image memory II 27 is a memory for storing the already input image data currently displayed on the screen in the bitmap format. Display memory 28
Is a frame memory that stores the image data of the screen displayed on the display unit 13a in a bitmap format.

The display control unit 29 reads the image data from the display memory 28, converts the image data into a serial video signal and outputs the serial video signal to the display unit 13a, and at the same time, the display unit 13a.
The horizontal / vertical synchronization signal is supplied to the display unit 13
The image of the image data stored in the display memory 28 is displayed on a.

The image processing section 31 receives an instruction from the CPU 21, and with respect to the image data in the image memory II 27 displayed in the edit target area set by the enclosing figure recognized by the image recognizing section 23,
The edit command memory 36 is created by inputting only the edit command or the enclosed figure recognized by the command recognition unit 24.
The edit process specified by the edit command read from is executed. In this editing processing, the arithmetic unit 33 is caused to execute processing such as converting the image data into bold characters. Then, new image data obtained by this editing process is sequentially written in the image development memory 32. And
When the editing process is completed, the image data stored in the image development memory 32 and obtained by the editing process is transferred to the corresponding area of the image memory II.

The image development memory 32 is a bit-map type memory for temporarily storing the image data of the area to be edited in the image memory II 27 which has been edited by the image processing section 31 as described above.

Under the control of the image processing unit 31, the arithmetic unit 33 performs a predetermined editing process such as converting the image data in the editing target area in the image memory II 27 into bold characters.

The page file 34 stores a plurality of pages of a document of one page (corresponding to one screen of the display unit 13) created by pen input. The CPU 21 writes this in the page file 34 each time a one-page document is created on the input / display device 13.

Next, a method of handwriting input for instructing deletion, font change, etc. in the embodiment of the above construction will be described with reference to FIG. FIG. 3 is a schematic diagram for explaining a method of inputting a surrounding figure when deleting a part of handwritten input data that has already been input. In the figure, a rectangular frame shows the display screen of the input / display device 13. Also, as shown in FIG. 3A, the six x marks 41 on the upper left side and the spiral mark 4 on the lower right side of the six x marks 41.
2 and the five triangles 43 below it indicate image data such as already input characters, numbers, or symbols.

After handwriting the image data with the pen 11 as described above, it is necessary to delete the six x marks 41 on the upper left side and the five Δ marks 43 on the lower right side. In this case, as shown in (a) of the figure, first, a circular enclosing figure 44 surrounding only the six X marks 41 to be deleted.
Specify the deletion area by writing one stroke. This surrounding figure 44
Can be closed or open.

On the device side, this written box figure 4
When 4 recognizes that it is a graphic image instructing to edit the inside of the box, the area inside the box figure 44 is automatically set as the edit target area.

Next, the user, as shown in FIG.
In the vicinity (immediately lower right in the example of the same figure) of the above boxed figure, "delete" which is a reserved editing command is entered. As a result, the image data (six x marks 41) surrounded by the enclosing graphic 44 is deleted (erased) as shown in FIG. Then, this edit command "delete" is automatically registered in the device.

Then, as shown in FIG. 6 (c), the user draws a square enclosing figure 45 that encloses all of the five Δ marks 43 in the lower right, and again designates the deletion area. As described above, the shape of the enclosing figure instructing to edit is not limited to any particular shape, and may be any shape that is recognized as the enclosing figure.

When the device recognizes that the written figure 45 is an enclosing figure, the area inside the enclosing figure 45 is automatically set as an edit target area, and the previously registered edit command "delete" is issued. This is executed for the image data (five Δ marks 43) of the set editing target area.

As a result, the image data (five triangles 43) designated by the enclosed figure 45 is converted into the image data (d) in FIG.
It is deleted (erased) as shown in. Note that the edit command that the user can enter together with the enclosing figure is not limited to "delete", but it is also possible to change the font such as bold character conversion,
In the case of color display, it is possible to input a command or the like for designating color change or the like.

Next, the operation for realizing the editing work such as the deletion of the surrounding figure by handwriting input and the change of the character style will be described with reference to the flowchart of FIG. When the user performs a handwriting operation (handwriting input) with the pen 11 on the input / display device 13, the coordinate input unit 13b causes the handwriting input coordinate position (normalized coordinate set on the coordinate input unit 13b at the pen operated position). The coordinate position in the system. In the present embodiment, the normalized coordinate system set in the display unit 13a and the coordinate input unit 13b match each other), and this coordinate data is detected by the CPU 21.
Is notified by interruption (S1).

The CPU 21 creates image data in which the input handwritten input coordinate data is the same as the locus drawn in time series, and writes it in the image memory I26 (S2).

When the handwriting input by the user is completed and the interruption from the coordinate input unit 13b is interrupted for a predetermined time or longer, the CPU 21 determines that the handwriting input is completed,
The image data newly written in the image memory I26 by handwriting this time and the already input / displayed handwritten input image data stored in the image memory II27 are OR-synthesized and written in the display memory 28.
The display control unit 29 reads out the OR-combined image data from the display memory 28 and causes the display unit 13a to display an image corresponding to the image data (S3).

By the above operation, when the user performs handwriting input on the input / display device 13 with the pen 11, the characters and figures input by the pen are immediately displayed on the input / display device 13 (see FIG. 3). .

Next, the CPU 21 checks whether or not the handwritten data written in the image memory I26 by the pen input is an enclosing figure (S4). In this process, C
The PU 21 transfers the image data of the handwritten input stored in the image memory I26 to the image recognition unit 23 and gives an instruction to determine whether the image data is an enclosing figure. The image recognition unit 23 checks whether or not the image data of the handwriting input is an enclosing graphic designating an area having a certain size or more, and notifies the CPU 21 of the recognition result. When the CPU 21 learns from this notification that the enclosing figure designating the edit area has been pen-input (S4, Yes), it then refers to the edit command memory 36 to check whether or not the edit command is stored (registered) ( S5).

Then, when it is found that the user is not registered (S
5, No), waiting for the next handwriting input, step S9-
In S11, the same processing as the above-described steps S1 to S3 is performed on the handwritten input image data following the input of the surrounding figure.

As a result, the image data such as the reserved edit command which is handwritten after the above-mentioned enclosing figure is input is immediately displayed on the input / display device 13 together with the enclosing figure (for example, FIG. 3). (See (b)).

Next, the CPU 21 inputs the image data handwritten after the input of the enclosing figure in the image memory I26 displayed on the input / display device 13 as described above by the reserved editing command. It is checked whether there is any (S12). In this process, the command recognition unit 24 converts the handwritten image data in the image memory I26.
, And instruct it to determine whether or not the edit command has been reserved (registered) in advance. Command recognition unit 24
Reserves the transferred image data in the reserved command memory 2
5 is compared with the edit command stored in 5, and the comparison result is notified to the CPU 21.

When the CPU 21 knows from this notification that the pre-reserved edit command has been input by the pen (S12,
Yes), the edit command is stored in the edit command memory 36.
Is registered (stored) in (S13).

Then, the editing process corresponding to the editing command is executed for all the image data displayed in the area surrounded by the enclosing figure in the image memory II 27 (S6).

Then, the contents (editing process result) in the image memory II 27 are displayed on the input / display device 13 (step S7). Next, after clearing the contents of the image memory I26 (step S8), the process returns to step S1.

As a result of the above operation, when the user hand-writes the "delete" command following the previously entered box figure, the "delete" command is registered and the "delete" command is executed. After executing the command,
The displayed enclosing figure and the command are erased, and the image data previously enclosed by the enclosing figure is erased as shown in FIGS. 3 (c) and 4 (c), for example. Also,
For example, when the "bold" command is input by handwriting, the image data previously surrounded by the enclosed figure is displayed in bold.

In step S12 described above, if the image data input by handwriting after inputting the enclosing figure is not a reserved edit command (S12, No), it is determined to be normal image data and the image memory I2
The image data in 6 and the image data in the image memory II 27 are OR-combined at corresponding bit positions,
The result obtained by this logical operation is the image memory II2.
7 (S15). Then, the process proceeds to step S8.

As a result, the normal handwritten image data input subsequently to the enclosed figure is directly input.
In step S5, if the handwritten input editing command has already been stored (registered) in the editing command memory 36 (S5, Yes), the CPU 21
Immediately proceeds to the process of step S6.

As a result, once the edit command is registered, the edit command can be continuously executed only by continuously inputting only the enclosing figure. If the image data input by handwriting is not the enclosing figure but the normal image data in step S4 (S4, No), it is determined that the editing process has been completed and is registered in the editing command memory 36. The edited command is deleted (S14), and the process proceeds to step S15.

By the above operation, when the user interrupts the continuous input of the enclosed figure, the execution of the edit command is terminated, the registration of the edit command is canceled, and the normal image data input / execution is resumed. Next, a second embodiment of the present invention will be described.

In the above-described first embodiment, only one edit command can be registered, and after registration, one registered edit command is executed by inputting an arbitrary enclosed figure. . On the other hand, in the second embodiment, one editing command is registered in correspondence with one enclosing figure, so that a plurality of editing commands can be registered in correspondence with a plurality of enclosing figures, and the registration is performed. By inputting a graphic similar to the predetermined enclosing graphic, it is possible to select and execute a desired edit command from among a plurality of registered edit commands.

The appearance and system configuration of the second embodiment are similar to those of the first embodiment shown in FIGS. 1 and 2. However, in the system configuration shown in FIG. 2, the contents stored in the edit command memory 36 are different from those in the first embodiment as described above.

Here, the method of registering the edit command in the edit command memory 36 in the second embodiment is schematically shown in FIG. As shown in the figure, the edit command memory 3
In FIG. 6, a plurality of handwritten input editing commands are stored in association with a plurality of types of enclosing figures (key figures) serving as keys. In the example of the figure, the "Delete" command that instructs the deletion of the data in the editing area using the circular enclosing figure with a partially open lower left as a key figure in order from the top,
The "red" command that specifies the red display of the data in the editing area that uses the downward U-shaped (square with the open bottom side) enclosing shape as the key shape, and finally consists of a pair of open parenthesis and closing parenthesis A "bold" command for instructing the bold display of the data in the editing area using the enclosed graphic as a key graphic is registered. These enclosing figures and edit commands are registered in the edit command memory 36 by the user's handwriting input by a predetermined method.

FIG. 6 and FIG. 7 are schematic diagrams for explaining a method of registering the enclosing figure and the edit command, and a method of executing the registered edit command. The four x-marks 51 at the upper side, the spiral mark 52 at the lower-left side thereof, and the two Δ-marks 53 at the lower-right side thereof shown in FIG. 6 (a) are respectively the characters, numbers, or symbols that have already been input. The image data of is shown.

Here, it is assumed that it is necessary to delete the upper four X marks 51. In this case, as shown in FIG. 7A, first, a circular enclosing figure 54 that encloses only the four crosses 51 to be deleted is drawn, and then shown in FIG. As described above, the edit command “delete” is entered in the vicinity of the above-described box figure (in this case, immediately lower right). This allows
Image data surrounded by a box 54 (4 x marks 5
1) is deleted (erased) as shown in FIG. At this time, the edit command "delete" and the circular enclosing figure 54 are displayed in the edit registration memory 36 as shown in FIG.
Will be automatically registered within.

After this, for example, when it becomes necessary to delete the image data (two Δ marks 53) below the deleted image data (four X marks 51), FIG.
As shown, the user has a circular enclosing figure 5 having the same shape as the enclosing figure 54 in which only the two Δ marks 53 are previously registered.
Simply surround it with 5. In other words, the enclosing figure 55 having the same shape as the enclosing figure 54 is drawn by one stroke according to the size of the image data to be deleted, and the deleting area is designated.

On the device side, this written figure 55
Is recognized as a circular enclosing figure similar to the enclosing figure 54 already registered, and the area inside the enclosing figure 55 is automatically set as the edit target area. Then, the edit command “delete” registered corresponding to the enclosing figure 54 is executed.

As a result, the image data (two Δ marks 53) surrounded by the enclosing figure 55 is deleted (erased) as shown in FIG. Next, with reference to the schematic diagram shown in FIG. 7, a handwriting input method for rewriting a part of handwritten input data that has already been input into bold characters will be described.

The two cross marks 61 on the upper left and the spiral mark 62 on the lower right of FIG. 9A indicate image data such as characters, numbers, or symbols that have already been input.

After such handwriting input, it is assumed that it is necessary to rewrite the two x marks 61 into bold letters. In this case as well, as shown in (a) of the same figure, an enclosing figure 63 (a pair of open parenthesis and a closing parenthesis) that surrounds only the image data (two crosses 61 in the example of the same figure) to be rewritten in bold type. )
Enter and specify the area to be converted to bold.

On the device side, the written box figure 6 is written.
3 is recognized as a graphic image for instructing editing inside the box, and the inside area of the box figure 63 is automatically set as the edit target area.

Next, the user, as shown in FIG.
The edit command "bold" is entered near the surrounding figure. As a result, the image data (two x marks 61) surrounded by the enclosing figure 63 are converted into bold characters as shown in FIG. Then, the edit command "bold" and a pair of parenthesized figures 63 are automatically registered in the edit command memory 36 as shown in FIG.

Next, it is assumed that the user also needs to convert the image data (one spiral mark 62) below the image data (two cross marks 61) just deleted to bold.
Also in this case, the user may simply enclose only the spiral mark 62 with an enclosing figure 64 having the same shape as the enclosing figure 63 previously registered to designate the area, as shown in FIG.

On the device side, this written figure 64
Is recognized as a pair of parenthesized box-shaped figures similar to the already registered box-shaped figure 63, and the inside area of the box-shaped figure 64 is automatically set as the edit target area, and the data in this edit target area is set. On the other hand, the edit command "bold" registered in correspondence with the box figure 63 is executed.

As a result, the edit command "bold type" registered in association with the enclosing figure 63 in advance is the image data (spiral mark 6) enclosed by the enclosing figure 64.
2), the spiral mark 6 is displayed as shown in FIG.
2 is converted to bold.

In this way, once the edit command is entered together with the enclosing figure to perform the editing, from the second editing, the enclosing figure corresponding to the desired edit command is simply entered and the edit area is designated. The desired edit is executed immediately.

Next, the operation of the second embodiment will be described with reference to the flowchart of FIG. When the user performs handwriting input with the pen 11 on the input / display device 13, steps S21 to S24 similar to steps S1 to S4 in the flowchart of FIG. 6 are performed, and either the enclosed figure or the normal image data is processed. It is recognized whether was input.

When the CPU 21 recognizes that it is an enclosing figure (S24, Yes), the enclosing figure is collated with the key figure stored (registered) in the edit command memory 36 to determine whether it is similar to any of the key figures. It is checked whether they are similar (S25).

If a key input figure similar or similar to the entered box figure is registered as a result of this comparison (S25, Yes), the edit command corresponding to the key figure is read from the edit command memory 36. (S2
6).

Then, the image memory II in the editing target area surrounded by the box-shaped figure input by handwriting this time II
The edit command is executed for the image data in 27 (S27).

In this editing process, the CPU 21 inputs
Based on the coordinate data of the box-shaped figure input by handwriting on the screen of the display device 13 or the storage position data of the box-shaped figure stored in the image memory I26, the area (editing target area) surrounded by the box-shaped figure is displayed. The corresponding area in the image memory II 27 is recognized.

By the above operation, if the read editing command is the "delete" command, the image memory II 27
The image data of the above-mentioned edit target area in is deleted.
On the other hand, if the edit command is a "bold" command, the image data of the edit target area in the image memory II27 is transferred to the image processing unit 31, and the processing for converting the transferred image data to the bold character is instructed.

The image processing unit 31 receives the instruction from the CPU 21, and causes the arithmetic unit 33 to execute a process of converting the image data into bold characters. Then, new image data obtained by this processing is written in the image development memory 32. Then, the image data stored in the image development memory 32 (image data converted to bold by the “bold” command) is transferred to the corresponding area of the image memory II.

Thereafter, the CPU 21 causes the image memory I
The image data in 26 and the image data in the image memory II 27 are OR-combined at corresponding bit positions, and the result obtained by this logical operation is used in the image memory.
Stored in II27 (S28), and further image memory
After clearing 26 (S35), the process returns to step S21 to wait for the next handwriting input.

On the other hand, if it is found in step S25 that the key figure similar or similar to the input box figure is not registered in the edit command memory 36 (S25, N).
o), the CPU 21 waits for the next handwriting input (S2).
9).

Then, in steps S29 to S31, the same processing as that in steps S21 to S23 described above is performed on the handwritten input image data following the input of the surrounding figure. As a result, the image data such as the edit command input by handwriting after the input of the surrounding figure is immediately displayed on the input / display device 13 together with the surrounding figure.

Then, the CPU 21 inputs and
It is checked whether or not the image data input by handwriting after the input of the enclosing figure in the image memory I26 displayed on the display device 13 is a pre-reserved edit command (S32). In this processing, the CPU 21 transfers the handwritten input image data stored in the image memory I26 to the command recognition unit 24, and gives an instruction to determine whether or not the editing command is reserved (registered) in advance. . The command recognition unit 24 collates the transferred image data with the edit command stored in the reserved command memory 25, and notifies the CPU 21 of the collation result.

When the CPU 21 knows from this notification that the pre-reserved edit command has been input by the pen (S31,
Yes), the edit command is stored (registered) in a predetermined area of the edit command memory 36 by using the previously input surrounding figure as a key (S33). Then, the above step S27
Go to processing.

As a result, when an edit command is input by handwriting after an enclosing figure not yet registered in the edit command memory 36, this editing command is registered using the enclosing figure as a key and surrounded by the enclosing figure. The edit processing is performed on the image data in the area in which the edit command is executed.

On the other hand, the CPU 21 executes the above step S32.
Then, when it is known that the normal image data is input (S3
2, No), the image data in the image memory I26 and the image data in the image memory II27 are OR-combined at corresponding bit positions, and the result obtained by this logical operation is stored in the image memory II27 (S3).
4), the process proceeds to step S35 described above. As a result, both the previously input surrounding graphic and the subsequently input image data are processed as normal image data. That is, even the enclosed figure can be input as normal image data.

In step S24, if the image data input by handwriting is not an enclosing figure, (S
24, No), it is determined that normal image data is input, and the process proceeds to step S34.

As a result, normal image data can be continuously input. In the first and second embodiments described above, as the edit command, a character image such as "delete" or "bold" indicating the edited content is input by handwriting, but the present invention is not limited to such an input method. For example, as shown in the upper part of the table shown in FIG. 9, the symbol image of the X mark or the sawtooth mark may be input by handwriting as a “delete” command. Also,
Similarly, as shown in the next row of the table, "copy"
As a command, a spiral mark with an upward arrow or a letter C surrounded by a circle may be input by handwriting. Also, the type of command is not limited to the above commands, and as shown in the next and subsequent stages, a “move” command for instructing movement of image data in the editing area,
It may be another command such as a "red" command for instructing to display the image data in the editing area in red. Then, the "move" command may be handwritten by inputting a circled letter M or a spiral mark with a downward arrow. Alternatively, the "red" command may be input by handwriting with the English character Red or the initial character R thereof.

Further, in the above embodiment, the editing is performed only on the image data input by handwriting input, but the present invention is not limited to this.
For example, it may be image data such as text data converted into a character code by handwritten character recognition or text data input from the outside by download or the like.
Further, in the present embodiment, the enclosed figure is input as the figure image for designating the edit target area, but the present invention is not limited to such an input method.
For example, key brackets may be written in the upper left corner and the lower right corner of the area in which the image data to be edited is displayed to specify the area. That is, if there is a handwritten image in which the area can be designated, it is not necessarily the enclosed figure.

[0096]

According to the present invention, when an edit target is designated and an edit command is entered and executed by a graphic image for area designation, the edit command is registered, and thereafter only the graphic image for area designation is manually input. Then, the registered edit command is executed on the image data whose area is specified by this graphic image. For this reason,
The image data can be edited on the screen easily and at high speed.

According to the second aspect of the present invention, since a plurality of edit commands can be registered by using graphic images having different shapes as keys, a graphic image to be input by handwriting according to a desired type of edit command can be registered. Can be used properly. Therefore, a plurality of types of editing can be performed easily and at high speed by handwriting input of different graphic images.
