  Hereinafter, an image display system 1 using the image display device of the present invention will be described. Each embodiment is described for convenience of explaining the present invention, and the scope of the present invention is not limited to the following embodiment.

[1. First Embodiment]
[1.1 System configuration]
First, the first embodiment will be described. 1st Embodiment is comprised including the terminal device 10 which is portable display apparatuses, such as a tablet, and stationary display apparatuses 20, such as a large sized display, as an image display apparatus.

  The terminal device 10 and the display device 20 are configured to be connectable. For example, in the present embodiment, communication is established via a LAN (wireless LAN, wired LAN). As another connection method, other short-distance wireless communication such as Bluetooth (registered trademark) or ZigBee (registered trademark) may be used. That is, any method may be used as long as the terminal device 10 and the display device 20 can communicate with each other.

[1.2 Functional configuration]
Subsequently, the functional configuration will be described with reference to the drawings.

[1.2.1 Terminal device]
First, the functional configuration of the terminal device 10 will be described with reference to FIG. The terminal device 10 includes a control unit 100, a display unit 110, a touch detection unit 120, an image processing unit 130, a communication unit 140, and a storage unit 150.

  The control unit 100 is a functional unit for controlling the entire terminal device 10. The control unit 100 realizes various functions by reading and executing various programs stored in the storage unit 150, and is configured by, for example, a CPU (Central Processing Unit).

  The display unit 110 is a functional unit that displays various contents and the like. For example, it is configured by an LCD (liquid crystal display), an organic EL display, or the like. The display unit 110 displays the entire image in the entire display area, and a graphic is displayed in the entire image.

  The touch detection unit 120 is a functional unit for realizing an operation input by detecting a touch operation from a user. For example, it is integrated with the display unit 110 and realized by a touch panel or the like. The touch operation may be detected using any method such as a capacitance method, an electromagnetic induction method, or an infrared method. Also, the detection location may be one point, or a plurality of points may be detectable.

  In addition, a graphic is input by the touch detection unit 120. For example, the touched coordinates input from the user are detected, and the stroke information is stored from the detected coordinates. The figure is recognized based on the stroke information and stored in the figure data 152. In addition, the figure is displayed on the entire image as it is.

  The image processing unit 130 is a functional unit for realizing image processing. As the image processing unit 130, for example, various images such as performing character recognition from an input figure (handwritten character) and outputting a text character, or cutting out an image of a surrounding area from the entire displayed image. Processing is realized. Also, processing is performed for converting stroke information into a figure, or converting vector data into raster data.

  The image processing unit 130 may be realized by being stored in the storage unit 150 as a program for each process as necessary, and read and executed as necessary.

  The communication unit 140 is a functional unit for the terminal device 10 to perform communication. For example, a wireless LAN such as IEEE802.11a / b / g / n is used, or near field communication such as Bluetooth is used. Note that general communication may be performed by LTE communication or the like.

  The storage unit 150 is a functional unit that stores various programs necessary for the operation of the terminal device 10 and various data. The storage unit 150 includes, for example, a semiconductor memory, an HDD (Hard Disk Drive), or the like.

  The storage unit 150 stores graphic data 152 and tag image data 154 in addition to various programs.

  The graphic data 152 includes handwritten characters and handwritten graphics based on stroke information stored by handwriting input (for example, stroke drawing), images input from other input devices (for example, a scanner), and the like. An image received and stored from the device is stored.

  For example, stroke information input by handwriting by the user is collected and stored as one grouped figure. Also, image files such as JPEG data and BMP data are stored from scanners, digital cameras, image files, and the like.

  Here, the figure in this specification is a concept including characters and symbols. Here, the characters (symbols) include handwritten characters that are characters written by the user with a touch pen, hand, mouse, etc., and text characters indicated by ASCII codes, JIS codes, Unicode, and the like.

  Accordingly, the graphic data 152 stores text characters (sequences) input by an input means such as a keyboard, received text characters (sequences), and the like. In this case, for example, text characters (columns), coordinates where the display area is located, and coordinates as the text area may be stored together.

  In addition, the figure may be composed of a character string that is a plurality of characters. That is, when handwriting is input, the stroke input at the first time interval is recognized as one handwritten character. Moreover, when this handwritten character is continuously input, it is recognized as a handwritten character string. These are stored in the graphic data 152 as a graphic.

  Each figure may store coordinates in the display area of the display unit 110. Then, each figure is displayed according to the coordinates, so that it is displayed on the display unit 110 as an entire image.

  The tag image data 154 is data generated by cutting out a part from a figure by the user. One or a plurality of cut out graphics may be stored as tag image data, or an image cut out from the entire image may be stored as tag image data. If the cut out figure is vector data or a figure based on stroke information, it may be converted into raster data and cut out.

[1.2.2 Display device]
Next, the functional configuration of the display device 20 will be described with reference to FIG. As shown in FIG. 3, the display device 20 includes a control unit 200, a display unit 210, an operation input unit 220, a communication unit 240, and a storage unit 250.

  The control unit 200 is a functional unit for controlling the entire display device 20. The control unit 200 realizes various functions by reading and executing various programs stored in the storage unit 250, and is configured by, for example, a CPU (Central Processing Unit).

  The display unit 210 is a functional unit that displays various contents and the like. For example, it is configured by an LCD (liquid crystal display), an organic EL display, or the like. The entire image is displayed on the display unit 210, and a figure is displayed therein.

  The operation input unit 220 is a functional unit for realizing operation input from a user. For example, an external keyboard, mouse, and display unit 210 are integrated with each other and realized by a touch panel or the like. The touch operation may be detected using any method such as a capacitance method, an electromagnetic induction method, or an infrared method. Also, the detection location may be one point, or a plurality of points may be detectable.

  The communication unit 240 is a functional unit for the display device 20 to perform communication. For example, a wireless LAN such as IEEE802.11a / b / g / n is used, or near field communication such as Bluetooth is used.

  The storage unit 250 is a functional unit that stores various programs and various data necessary for the operation of the display device 20. The storage unit 250 includes, for example, a semiconductor memory, an HDD (Hard Disk Drive), or the like.

  In addition to the various programs, the storage unit 250 stores graphic data 252, sticky note image data 254, and sticky note data 256.

  The graphic data 252 stores a graphic input in the display device 20 and a graphic received from the terminal device 10. The stored graphic data is displayed in the display area of the display unit 210. Since the graphic data 252 is stored as the same type of data as the graphic data 152, detailed description thereof is omitted.

  Also, the tag image data 254 is received from the terminal device 10. Based on the sticky note image data 254, sticky note data 256 is generated and stored.

  Here, the sticky note data described in the present embodiment is data that makes it possible to manage a figure as one unit. The tag data is not only displayed, but can be changed in color or moved and displayed in the display area.

  What is included as the tag data may be a graphic included in the tag image data, or may be a text character converted from a handwritten character. In addition, the tag data may be displayed / hidden switched, pasted, or deleted freely.

  The sticky note data may be displayed superimposed on other displayed content (for example, a graphic or an image), or may be displayed alone.

[1.3 Process flow]
Next, the flow of processing in the present embodiment will be described with reference to the drawings.

[1.3.1 Overview of processing]
First, generation of sticky note data in the present embodiment will be described. Here, although the case where it performs in the terminal device 10 is demonstrated, you may perform in the display apparatus 20. FIG. Moreover, as will be described later, the processing may be performed separately between the terminal device 10 and the display device 20 by processing.

  4A, the handwritten character string B10 “Deadline” is displayed as a graphic. The handwritten character string B <b> 10 is displayed on the display area of the display unit 110.

  The user selects (specifies) the handwritten character string B10 so as to surround it. The area specified by the selection at this time is defined as a surrounding area R10. That is, since this stroke is formed so as to surround the handwritten character string B10, it is recognized that it is a sticky note selection input.

  When it is recognized that the input is a tag selection input, the coordinates of the surrounding area are acquired so as to include the handwritten character string B10. The coordinates of the surrounding area are the coordinates of the area R12 in FIG. The handwritten character string B10 included in the region R12 is recognized as the tag image data T10 (FIG. 4C).

  The data recognized as the tag image data T10 can be transmitted to another device. Also, FIG. 4D shows the conversion from the tag image data T10 to the tag data H10. In this figure, the handwritten character string “deadline” is converted into the text character string “deadline” by being converted to the tag data H10. By converting to a text character string, it becomes possible to add or edit text characters. The tag data stores tag attributes (information attached to the tag) such as color information, shape, user, and size.

  In addition, a plurality of figures may be selected in the surrounding area. In this case, it is good also as displaying sticky note data for every figure, and good also as displaying collectively as one sticky note data. When different types of figures (for example, characters and images) are selected, the sticky note data may be displayed for each figure or the sticky note selection input may be canceled.

[1.3.2 Sequence diagram]
Next, the first embodiment will be described with reference to FIG. FIG. 5 is a sequence diagram showing processing on the transmitting side for transmitting the tag image data based on the tag data and processing on the receiving side for reception. In the present embodiment, the terminal device 10 is described as an example of the transmission side, and the display device 20 is described as an example of the reception side.

  First, when handwritten input is detected by the terminal device 10 (step S102; Yes), input coordinates are acquired (step S104). The acquired coordinates are stored as stroke information (step S106).

  If no surrounding area is formed (step S108; No), the stored stroke information is stored in the graphic data 152 as a graphic. For example, any conventional technique may be used as a method of storing the stroke information as, for example, handwritten characters (columns) or as line segments.

  If the stroke forms a surrounding area (step S108; Yes), it is determined that a sticky note is selected and the coordinates of the surrounding area are acquired (step S110).

  Here, as the coordinates of the surrounding area, for example, coordinates including the surrounding area may be extracted. Here, it may be determined whether or not the position of the surrounding area is a predetermined position (step S112). Specifically, for example, a position that can be recognized as a sticky note selection input in the input possible area may be set, and may be recognized as a sticky note selection input when a surrounding area is formed at the position.

  Further, when the process is executed in the entire display area, the determination in step S112 may not be performed. That is, the process may proceed to step S114 after step S110.

  Subsequently, the sticky note image data is acquired based on the surrounding area (step S112; Yes → step S114). That is, a figure included in the surrounding area is acquired and acquired as sticky note image data. Then, the acquired tag image data is transmitted to the display device 20 on the receiving side (step S116).

  When receiving the tag image data (step S150), the display device 20 on the receiving side converts the tag image data into tag data based on the tag image data (step S152). Specifically, when handwritten characters (strings) are included in the tag data, a process of converting into text characters (strings) is performed. In addition, you may display as a handwritten character (sequence) as it is.

  Subsequently, the display position of the tag data is determined (step S154), and the tag data is displayed (step S156).

  There are a plurality of methods for determining the display position of the tag data. First, a method of determining a position for displaying sticky note data as an initial setting and displaying the sticky note data at the initial setting position is conceivable. In addition, the display position of the tag data may be determined by the terminal device 10 that has transmitted the tag image data. For example, the screen may be divided into four and the area to be displayed for each terminal may be determined.

[1.4 Operation example]
Next, an operation example in the present embodiment will be described with reference to FIG. In FIG. 6A, two graphics are displayed in the display area of the terminal device 10. A handwritten character string B100 “Idea” and a handwritten character string B110 “Deadline” are displayed.

  At this time, the rectangle R100 is input by the user. Since this input is a surrounding area, it is recognized as a sticky note selection input. The handwritten character string B100 included in the rectangle R100 is acquired as sticky note image data.

  This sticky note image data is transmitted from the terminal device 10 to the display device 20. The display device 20 displays the tag data H100 based on the tag image data. In the tag data H100, the handwritten character string “idea” is converted into a text character string “idea” and displayed.

  The tag data H100 can be freely moved by the user, and the size can be changed. In addition, as in the present embodiment, it is possible to edit a character (string) by being converted into a text character.

  As described above, according to the present embodiment, the user performs an operation of enclosing a necessary graphic, thereby transmitting the graphic input by one image display device to another image display device as sticky note data and displaying it. can do.

  Thereby, for example, an input operation can be performed using a terminal device (for example, an image display device such as a tablet) used by the user. Further, even when there are a plurality of users, it is possible to input a graphic from each terminal device and transmit it.

[2. Second Embodiment]
A second embodiment will be described. The second embodiment is processing for recognizing the attributes of tag data based on the selection input method in tag selection input. In other words, the attribute of the tag data is recognized in accordance with the attribute of the area (enclosed area) selected and input.

  Note that the system configuration in the present embodiment is the same as that of the first embodiment described above, and a description of the configuration and the like is omitted. In the present embodiment, description will be made centering on points different from the first embodiment.

[2.1 Data structure]
7 replaces the storage unit 150 in the first embodiment with a storage unit 150b. As shown in FIG. 7, the storage unit 150b stores graphic data 152, tag image data 154, and a tag data attribute determination table 156.

  The tag data attribute determination table 156 is a table that stores the tag data attribute according to the attribute of the surrounding area input as a tag selection input, in this embodiment, the surrounding area stroke (shape). For example, as shown in FIG. 8A, the attribute (for example, “red” as the color) of the tag data is stored in association with the stroke shape (for example, “circular”) that is the attribute of the region.

  In this embodiment, color is used as an example of the attribute of the tag data, but other display patterns such as size (font size), font type, and border color of the tag data may be stored.

[2.2 Process flow]
The processing flow of this embodiment will be described based on the sequence diagram of FIG. In addition, the same code | symbol is attached | subjected to the process same as 1st Embodiment, and the description is abbreviate | omitted.

  If the detected stroke is a surrounding area and it is determined that a sticky note is selected (step S102 to step S112; Yes), the shape of the enclosed stroke is determined (step S202), and the determined stroke shape is determined. Based on the tag, the attribute of the tag data (tag data attribute) is determined (step S204). Specifically, the tag data attribute is determined based on the tag data attribute determination table 156.

  Subsequently, sticky note image data is acquired based on the surrounding area (step S114). Thereafter, the acquired sticky note image data and sticky note data attributes are transmitted to the display device 20 (step S206). In addition, you may transmit as other information (for example, various information, such as a tag size), and tag additional information including a tag data attribute.

  Further, the flow of processing in the present embodiment is an example, and may be changed within a range where no contradiction occurs in the data. For example, the tag data attribute may be determined after first acquiring the tag image data based on the surrounding area (step S206 → step S204).

  The display device 20 receives the tag image data and the tag data attributes (step S252). Thereafter, it is converted into sticky note data, and the sticky note data display position is determined (steps S152 → S154).

  Then, the attribute of the tag data is determined based on the received tag data attribute (step S254). Then, the sticky note data is displayed based on the determined attribute of the sticky note data (step S256).

[2.3 Example of operation]
The operation example of 2nd Embodiment is demonstrated based on FIG. FIG. 10A is a diagram in which sticky note data H100 based on the sticky note image data transmitted from the terminal device 10 is displayed on the display device 20 in the first embodiment.

  In this state, the “deadline” that is the handwritten character string B110 is selected in the surrounding area R110 indicated by the stroke. In this case, tag image data including the handwritten character string B110 is acquired and transmitted to the display device 20. At this time, the attribute of the tag data is also transmitted.

  In the display device 20, FIG. 10B shows the tag data H110 converted from the received tag image data. As in the case of the sticky note data H100 of the first embodiment, the case where the shape of the stroke of the surrounding area is a rectangle and the case where the shape of the stroke of the surrounding area is a circle as in the case of the sticky note data H110 of the present embodiment. Data attributes have changed. That is, the sticky note data H100 and the sticky note data H110 are displayed in different colors.

  As described above, according to the present embodiment, the attribute of the tag data can be easily switched by switching the shape to be selected when the user selects the graphic.

  Further, the shape of the stroke of the surrounding area for determining the attribute of the tag data and the attribute of the tag data may be arbitrarily set by the user. Thereby, a favorite attribute (for example, color) can be assigned to a favorite shape.

  Further, the tag data attribute determination table 156 may be stored in the display device 20 and the attribute determination of the tag data may be performed by the display device 20. In other words, the sticky note image data and the stroke information of the surrounding area are transmitted from the terminal device 10 to the display device 20. Then, the display device 20 may determine the attribute of the tag data from the transmitted information.

[3. Third Embodiment]
A third embodiment will be described. In the third embodiment, the display attribute such as color is set as the attribute of the tag data, but a content attribute may be set.

  In the third embodiment, the tag data attribute determination table 156 in FIG. 8A is replaced with the tag data attribute determination table in FIG. 8B in the second embodiment.

  That is, an attribute (for example, “high” as importance) is stored in association with the stroke shape. That is, it is possible to add a content attribute such as importance as an attribute of the tag data. These attributes may be attributes such as “erasable” and “non-erasable”, and attributes indicating the owner (for example, Mr. A for a circle and Mr. B for a rectangle).

  The sticky note data is displayed according to the determined attribute of the sticky note data (steps S254 → S256 in FIG. 9). Thereby, the sticky note data behaves according to the sticky note data attribute. For example, if the tag data with the importance level “high” is set to “cannot be deleted”, the user cannot delete the tag data.

  The display device 20 may change the display format according to these attributes. For example, a high importance item may be displayed in “red” or “large”.

  As described above, according to the present embodiment, it is possible to easily attach the attribute of the tag data based on the drawing pattern other than simple display.

[4. Fourth Embodiment]
A fourth embodiment will be described. In the fourth embodiment, when an attribute is attached to tag data, the attribute is set based on the attribute of the surrounding area, not the shape of the stroke.

  In the fourth embodiment, the tag data attribute determination table 156 in FIG. 8B is replaced with the tag data attribute determination table in FIG. 8C in the third embodiment. That is, as the attribute of the surrounding area, for example, the attribute of the tag data (the owner “A” in this embodiment) is associated with the attributes such as “clockwise” and “counterclockwise”.

  For example, as an attribute of the surrounding area, it is also possible to set, for example, “a stroke of the surrounding area is detected with two fingers” or “the surrounding area is input together with other operations”. .

  Further, as described above, other attributes such as size, color, and importance may be set as the attribute of the tag data.

  For example, an operation example of the fourth embodiment is shown in FIG. On the terminal device 10, a handwritten character string B200 and a handwritten character string B210 are displayed. Then, the handwritten character string B200 is selected as the surrounding area R200 clockwise, and the handwritten character string B210 is selected as the counterclockwise surrounding area R210.

  Here, the tag data selected and converted by the surrounding area is displayed on the display device 20. Since the tag data H200 and the tag data H210 have different attributes, the display is also different.

  As described above, according to the present embodiment, it is possible to easily change the attribute of the tag data according to the way of selecting the surrounding area when the tag selection input is performed.

[5. Fifth Embodiment]
The fifth embodiment is an embodiment in the case where recognition of tag data is performed on the display device 20 side. The present embodiment is an embodiment in which the processing flow shown in FIG. 5 of the first embodiment is replaced with FIG. Based on FIG. 12, the flow of processing of the present embodiment will be described.

  In the terminal device 10, an image including a graphic is displayed. Among these, a graphic as tag data is selected in the surrounding area, and the image data is transmitted to the display device 20 (step S302).

  When receiving the image data (step S310), the display device 20 executes a graphic recognition process from the received image data (step S312), and acquires a graphic from the image.

  Here, various methods are conceivable as a method for acquiring a graphic from an image. When stroke information is transmitted together with image data, the graphic is recognized with reference to the stroke information. When the image is vector data, the figure is recognized with reference to the vector data. In the case of raster data, the figure is recognized from the figure shape.

  Here, when predetermined graphic data is detected in the recognized graphic, the shape of the detected graphic is determined (step S314; Yes → step S316). For example, the shape of the surrounding area is detected, or the shape of a figure when another figure is included in the surrounding area is detected. Then, it is determined that the detected shape is a sticky note selection input, and a graphic included in the detected area is acquired as sticky note image data (step S318).

  Then, the tag image data is converted to the tag data, the display position of the tag data is determined (step S320), and the attribute of the tag data is determined (step S322). Then, the sticky note data is displayed based on the converted sticky note data, the display position and the attribute of the sticky note data (step S324).

  If not all the sticky note data included in the image is displayed, the process is repeatedly executed (step S326; No-> step S316). If displayed, the process is terminated (step S326; Yes).

  As described above, according to the present embodiment, the necessary sticky note data can be displayed on the display device 20 by transmitting the images collectively from the terminal device 10. There is no need to transmit the sticky note image data each time, and the communication traffic between the terminal device 10 and the display device 20 can be reduced. In addition, when the display device 20 has a higher processing capability than the terminal device 10, an effect that the processing can be performed collectively can be expected.

[6. Sixth Embodiment]
Subsequently, a sixth embodiment will be described. In the sixth embodiment, when the sticky image data is acquired based on the surrounding area selected as the sticky note selection input, even if the sticky image data is out of the surrounding area but is in the same graphic group, the sticky image data is acquired. It is a form.

  In this embodiment, in step S114 of the processing flow of FIG. 5 of the first embodiment, the sticky note image data is acquired based on the surrounding area. That is, in the first embodiment, a graphic included in the surrounding area is acquired as sticky note image data.

  In this embodiment, when a part of the figure is included in the surrounding area, the figure is acquired as sticky note image data.

  This will be described with reference to FIG. The handwritten character string B400 in FIG. 13 constitutes one figure with “idea”. That is, handwritten characters such as “A” are configured based on the stroke information. The handwritten characters “I”, “De”, “A” gather, and the handwritten character string “Idea” is formed.

  Here, the encircling region R400 includes an “ideal” portion. However, the graphic including “ide” is the handwritten character string B400 “idea”. Therefore, in this case, the “idea” graphic is acquired as a graphic included in the surrounding area.

  Then, “idea” is displayed as the tag data H400 on the display screen of the display device 20. That is, the handwritten character string “idea” is converted into the text character string “idea” and displayed as sticky note data.

  As described above, according to the present embodiment, when the user selects a graphic including a handwritten character string, the region including the graphic may be selected.

[7. Seventh Embodiment]
A seventh embodiment will be described. The seventh embodiment is an embodiment in the case where a selection operation is performed before transmission for tag image data selected by the surrounding area.

  The seventh embodiment is an embodiment in which the processing of the terminal device 10 shown in FIG. 5 in the first embodiment is replaced with the processing flow of FIG. In addition, about the process same as FIG. 5, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  After acquiring the tag image data based on the surrounding area (step S114), it is determined whether or not there is a touch operation on the surrounding area (step S502). Here, if there is a touch operation, the acquired tag image data is transmitted to the display device 20 (step S116).

  An example of operation in the present embodiment is shown in FIG. In FIG. 15A, the handwritten character string B500 is selected by the surrounding area R500. At this time, when the user touches (performs a tap operation) in the surrounding area R500, the tag image data is transmitted to the display device 20. As a result, the tag data H500 is displayed as shown in FIG.

  As described above, according to the present embodiment, after the tag image data is selected by the surrounding area, the user can transmit the tag image data at an arbitrary timing. Thereby, for example, when a plurality of sticky note data is displayed, it is possible to display them in an order that the user likes.

  In addition, as a process of step S502, what is performed after step S114 is an example, For example, you may perform before step S114. That is, the sticky note image data may be acquired after the touch operation is detected.

  Further, step S502 may determine a predetermined time timing as the detection timing. For example, if there is no touch operation within 5 seconds, the tag image data may be canceled (that is, not selected).

[8. Eighth Embodiment]
An eighth embodiment will be described. The eighth embodiment is an embodiment in the case where a cancel operation is performed before transmission for the tag image data selected by the surrounding area.

  The eighth embodiment is an embodiment in which the processing flow of the terminal device 10 shown in FIG. 5 in the first embodiment is replaced with the processing flow of FIG. In addition, about the process same as FIG. 5, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  After the tag image data is acquired based on the surrounding area (step S114), it is determined whether or not a touch operation has been performed outside the surrounding area (step S522). Here, if there is a touch operation outside the area, the acquired tag image data is canceled and the tag image data is not transmitted to the display device 20 (step S524).

  On the other hand, if no touch operation is detected outside the area, the acquired tag image data is transmitted (step S522; No → step S116). Note that whether or not there is a touch operation outside the area is determined based on whether or not the touch operation is performed within a predetermined time. For example, if the touch is not made within 3 seconds, the result of step S522 is No, and the acquired tag image data is transmitted to the display device 20.

  An operation example in this embodiment is shown in FIG. In FIG. 17A, the handwritten character string B520 is selected by the surrounding area R520. At this point, when the user touches (tap-operates) P520 outside the surrounding area R520, the tag image data selected by the surrounding area R520 is cancelled.

  That is, as shown in FIG. 17B, the sticky note data is not displayed on the display device 20 due to the cancellation.

  Thus, according to this embodiment, the user can cancel the tag image data after the tag image data is selected by the surrounding area. Thereby, for example, even when an unnecessary figure is selected, it is possible to prevent the display from being displayed on the display device by canceling.

[9. Ninth Embodiment]
A ninth embodiment will be described. The ninth embodiment is an embodiment that switches from stroke information to normal graphic input instead of sticky note selection input.

  Although this embodiment can be described in combination with the above-described embodiment, for example, a case where it is combined with the eighth embodiment will be described.

  That is, in the eighth embodiment, the processing for canceling the sticky note image data is executed in step S524 of FIG. 16, but at this time, a diagram may be actually drawn on the terminal device 10 based on the stroke information. .

  An example of the operation in this case is shown in FIG. FIG. 18A is the same as FIG. 17A of the eighth embodiment, and the surrounding area R520 is selected around the handwritten character string B520. The user touches P520 outside the area of the surrounding area R520.

  In this case, as shown in FIG. 18B, the surrounding area R520 is displayed as a figure B522 which is a diagram as it is. That is, the stroke information of the sticky note selection input is used as it is as the stroke information for drawing the figure.

  Thus, according to the present embodiment, the user can input by switching between the tag selection input and the graphic drawing input. This switching may be combined with other embodiments. For example, the switching may be performed according to the shape of the surrounding area, or may be switched depending on the attribute of the surrounding area. Further, in the seventh embodiment, it may be configured such that a figure drawing input (that is, no sticky note image data is not transmitted) is made when the inside of the surrounding area is touched, and sticky note image data is sent when nothing is done.

[10. Tenth Embodiment]
A tenth embodiment will be described. The tenth embodiment is an embodiment in which an operation is performed by displaying a menu after selecting a figure in the surrounding area.

  An operation example of this embodiment will be described with reference to FIG. FIG. 19A is a diagram when the handwritten character string B600 is selected by the surrounding area R600. At this time, a menu display M600 is displayed on the display screen of the terminal device 10.

  Here, when the user selects a subsequent operation from the menu displayed on the menu display M600, the behavior with respect to the tag image data is determined. For example, when “transfer sticky note” is selected, sticky note data H600 is displayed as shown in FIG.

  At this time, the attribute of the tag data may be selected from a menu and set. Further, various behaviors such as drawing processing and image transfer may be selected.

  Thus, according to the present embodiment, by using the menu display, the user can select a plurality of behaviors for the tag image data.

[11. Eleventh Embodiment]
An eleventh embodiment will be described. In the eleventh embodiment, a case will be described in which recognition is performed as tag image data when a figure is included in the surrounding area.

  In the embodiment described above, a graphic included in the surrounding area is acquired and used as sticky note image data. For example, in FIG. 5 in the first embodiment, the tag image data is acquired based on the surrounding area in step S114.

  Here, when graphic data is not included in the surrounding area, the tag image data may not be acquired.

  That is, in step S114, graphic data included in the surrounding area is acquired based on the surrounding area. In this case, if graphic data is not included in the surrounding area, the tag selection input is canceled. That is, in this case, the tag image data is not acquired and is not transmitted to the display device 20.

  Further, when the tag image data is not acquired, a line segment may be drawn based on the stroke information input as the surrounding area.

  By adopting such a configuration, the sticky note data is displayed on the display device by selecting so as to surround the portion including the graphic, and if the graphic is not included, the line segment is drawn It becomes.

[12. 12th Embodiment]
A twelfth embodiment will be described. In the twelfth embodiment, when tag image data is transmitted from the terminal device 10, information held by the terminal device 10 is transmitted.

  For example, various information is stored in the terminal device 10. For example, the information held by the terminal device 10 includes various information such as setting information such as an IP address and identification information unique to the terminal device, login information (user name), and user information such as a user name input by handwriting. It is remembered. The setting information and user information will be described together as environment information of the terminal device 10 below.

  The environmental information stored in the terminal device 10 is transmitted to the display device 20 in step S116 of the first embodiment.

  Here, the environment information may be information stored in advance, or may be information set and stored by the user. Further, it may be information set at the time of factory shipment, such as terminal-specific information (terminal manufacturing identification information, MAC address, etc.).

  In addition to login information, user information (user name) associated with a handwritten input figure may be used. This user information may be terminal login information or information linked to an input device (for example, a touch pen).

  By transmitting these environmental information to the display device 20, in step S152, the color of the sticky note, the size of the sticky note, and the transmittance are changed based on the information held by the terminal device 10 such as the environmental information. It is possible to change attributes such as changing.

[13. 13th Embodiment]
A thirteenth embodiment will be described. The thirteenth embodiment is an embodiment in which the display form is changed on the display device 20 based on the attribute information and the environment information transmitted together with the tag image data in the twelfth embodiment.

  Specifically, the display device 20 can select display based on the attribute, or can display environment information (for example, display a user name together with tag data). For example, the user name is displayed together with the tag data, the IP address of the transmitted terminal, the machine name, etc. are displayed.

  The display device 20 can perform switching between valid / invalid of attributes and display / non-display of environment information.

  An operation example in the present embodiment is shown in FIG. FIG. 20A is a diagram showing the display device 20 when the environmental information is “ON”. For example, the user display is set to “ON” in the region R700.

  In this case, the user name “A” is displayed in the vicinity of the tag data H700. A user name “B” is displayed near the tag data 710.

  At this time, FIG. 20B shows a case where the user display is turned “OFF” by operating the selection of the region R700. In FIG. 20B, the user name is not displayed in the vicinity of the tag data H700 and the tag data H710.

  Thus, according to the present embodiment, it is possible to display / hide environmental information on the display device 20. Note that the terminal device 10 may perform switching between display / non-display of the environment information. Further, for example, display / non-display as the entire setting may be switched, or may be switched for each tag data. The display / non-display may be switched depending on the shape of the surrounding area.

[14. 14th Embodiment]
A fourteenth embodiment will be described. In the fourteenth embodiment, display / non-display of sticky note data is switched using environmental information and attributes.

  For example, attributes and environment information are stored for each piece of tag data. Therefore, the user can select and display the tag data to be displayed in a batch or hide the data.

  An example of the operation in this embodiment is shown in FIG. In FIG. 21, the tag data to be displayed is selected in the surrounding area R800. Specifically, the user A's tag data is displayed and the user B's tag data is selected to be hidden.

  In this case, for example, as compared with FIG. 20A, the sticky note data H800 in which the user A is stored as the environmental information is displayed, but the sticky note data in which the user B is stored as the environmental information is displayed. It has not been.

  In the above-described embodiment, environment information has been described as an example. However, for example, display / non-display may be switched by designating attributes of sticky note data such as color and shape. The display / non-display switching may be switched from the terminal device 10.

  Further, a plurality of environmental information and attributes may be combined. For example, display / non-display may be switched by a combination of sticky data with a high importance of Mr. A and red sticky data of Mr. B.

[15. Fifteenth embodiment]
A fifteenth embodiment is described. In the description of the above-described embodiment, the case where the terminal device 10 and the display device 20 communicate with each other has been described. However, an embodiment in which processing is executed by the terminal device 10 or the display device 20 alone will be described.

  FIG. 22 is a processing flow for explaining processing executed by the terminal device 10 or the display device 20. This is a process for realizing the operation of the second embodiment only by each device. It is assumed that the apparatus that executes the process of FIG. 22 stores the data in the storage unit shown in FIG.

  The same processes as those in the process flow shown in FIG. 9 are denoted by the same reference numerals, and the description thereof is omitted. In FIG. 9, the terminal device 10 acquires (recognizes) tag data (tag image data, tag data attributes) and the display device 20 displays the tag data, but the processing in FIG. Realized with the same device.

  That is, the attribute of the tag data is determined from the shape of the enclosed stroke by handwriting input from the displayed graphic (step S102; Yes → S104 → S106 → S108; Yes → S110 → S112; Yes → S202). → S204). Then, sticky note image data is acquired based on the surrounding area (step S114).

  The acquired tag image data is converted into tag data (step S152), and the display position of the tag data is determined (step S154). When the tag data attribute is determined (step S254), the tag data is displayed (step S256).

  Here, what is displayed as the tag data may be displayed by replacing the original selected figure, or may be displayed on a display (for example, another area). For example, FIG. 23 is an example of a screen example when realized by the terminal device 10.

  As shown in FIG. 23A, the handwritten character string B800 is selected in the surrounding area R800. At this time, as shown in FIG. 23B, the handwritten character string B800 is replaced and displayed as the tag data H800.

  FIG. 24A shows a state where a handwritten character input area and a graphic display area (sticky note data display area) are separated. For example, the handwritten character string B850 is input and displayed in the handwritten character input area at the bottom of the display screen.

  Here, the handwritten character string B850 is selected by the closed region R850, whereby the tag data H850 is displayed. At this time, the tag data H850 is displayed separately from the handwritten character string B850. Note that, as described in the above-described embodiment, for example, “Mr. A” can be displayed as the name of the input person (owner) in the tag data H850 in FIG.

  Thus, according to the present embodiment, it is possible to execute the same processing even in the same apparatus. In this embodiment, the flow of the second embodiment has been replaced. However, in other embodiments, the tag image data and the tag data attribute are determined and displayed based on the tag image data and the tag data attribute. Of course, it is possible.

  For convenience of explanation, it is described as being converted to sticky note data, but it is of course possible to display directly based on, for example, sticky note image data and attributes of the sticky note data.

[16. Sixteenth Embodiment]
A sixteenth embodiment will be described. In addition to the fifteenth embodiment, an embodiment in which the data is once stored as sticky note data will be described.

  25 and 26 are process flows for explaining the process executed by the terminal device 10 or the display device 20. This is a process for realizing the operation of the second embodiment only by each device. It is assumed that the apparatus that executes the processing of FIGS. 25 and 26 stores the data in the storage unit shown in FIG.

  The same processes as those in the process flow shown in FIG. 9 are denoted by the same reference numerals, and the description thereof is omitted. In FIG. 9, the terminal device 10 acquires (recognizes) tag data (tag image data, tag data attributes) and the display device 20 displays the tag data, but FIG. 25 and FIG. 26 processes are realized by the same apparatus.

  That is, when the process of FIG. 25 is executed, the user's operation acquires the tag image data and the tag data attribute (steps S102 to S114), and stores the tag image data and the tag data attribute ( Step S602).

  When the process of FIG. 26 is executed, the sticky note image data and sticky note data attributes stored in step S602 are read (step S652), converted into sticky note data, and displayed (steps S152 to S256). ).

  Thus, according to the present embodiment, it is possible to execute the same processing even in the same apparatus. In the present embodiment, the flow of the second embodiment has been described. However, in other embodiments, the tag image data and the tag data attribute are stored in the terminal device, and the stored tag image data and tag data are stored. Of course, it is possible to display based on the attribute.

  Also, once sticky note data is stored, it becomes possible to exchange sticky note data in different programs and processes. In addition, by specifying an external storage device (for example, a USB memory) as the storage location of the sticky note data, it can be displayed on another device that is not directly connected.

[17. Seventeenth Embodiment]
A seventeenth embodiment will be described. In the seventeenth embodiment, in addition to the above-described embodiments, a case where the timing of sending sticky note data is different will be described.

  That is, in the above-described embodiment (for example, the first embodiment), the sticky note data is transmitted with the operation surrounding the figure as a trigger, but the figure is specified when the no-operation state continues for a certain time after the entry, The identified figure is transmitted as sticky note data.

  In this case, an area where data from the timing when the no-operation state has continued for a certain time last time is cut out as a rectangular area and transmitted as tag data. The processing of this embodiment will be described with reference to FIG. Note that FIG. 27 replaces the processing flow of FIG. 5, and the same processes are denoted by the same reference numerals and description thereof is omitted.

  After the stroke information is stored, it is determined whether or not a certain time has passed (step S702). Here, when a predetermined time has elapsed, the coordinates of the rectangular area that becomes the tag image data are acquired (step S704). If the position of the rectangular area is within the predetermined area (step S706; Yes), the tag image data is acquired based on the rectangular area (step S708).

  For example, according to the example of FIG. 6, by handwriting “idea” and continuing the non-operation state for a certain period of time, the rectangular region is cut out so that the portion described as “idea” fits. In the cutting out of the rectangular area, it may be cut out in a rectangular area in which the handwritten text fits, or the angle of the rectangular area to be cut out may be adjusted in consideration of the inclination of the handwritten character. By adjusting the rectangular area, data equivalent to the rectangle R100 is generated.

  In step S702, the tag determination ON means that it is necessary to distinguish between normal handwriting input and tag data input. Therefore, an operation such as changing the input mode between normal handwriting input and tag data input is performed. Also good. When the sticky note data input mode is “ON” or when handwritten input is performed after the pen mode for sticky note data input is selected, the sticky note determination is turned on. If the sticky note determination is ON, sticky note image data is acquired.

  Specifically, a mode for performing normal handwriting input (handwriting input mode) and a mode for performing handwriting input that can be converted into tag data (tag data input mode) can be selected. Here, when the tag data input mode is selected and handwriting input is performed, the processing of the present embodiment is executed. That is, after handwriting input, it is converted into sticky note data (sticky note image data) after a predetermined time has elapsed. Here, the handwritten input input in the handwriting input mode, which is the normal input mode, is not converted into sticky note data (sticky note image data) even after a predetermined time has elapsed. As described above, for example, when the tag data input mode is selected as the specific input mode, the data is converted into tag data.

  For example, as described in the first embodiment, when an input figure is enclosed (an enclosed area is formed by a stroke), it is converted into sticky note data (sticky note image data). In the present embodiment as well, an operation of surrounding the inputted figure may be an operation of converting to sticky note data before a predetermined time elapses.

  Note that the tag determination ON may be switching of a tag data input mode, a mode ON switch, or the like. In addition, in the case of a predetermined operation (for example, an operation is performed while pressing a button of a pen, a hand-written input is performed while touching with one hand), sticky note determination may be determined to be ON.

  In addition, depending on the system, when input to a predetermined area, all may be determined as sticky image data, or all handwritten input may be converted into sticky image data.

  Further, in the above-described embodiment, the “rectangular region” is described. However, it may be a surrounding region (closed region), and may be various shapes such as a circle, an ellipse, a triangle, and a trapezoid. The user may set the shape of the area.
