Description

  The present invention relates to a computer apparatus and a program for printing a coded pattern that can be read by an electronic pen together with an image of a slide generated by an application.

  An electronic pen that digitizes written information has been developed. A typical example is the “Anoto pen” developed by Swedish company Anoto. Anotopen is used with dedicated paper on which a predetermined dot pattern is printed. In addition to the usual ink cartridge for writing characters, etc., the anotopen has a small camera for capturing the dot pattern printed on the dedicated paper and the position coordinates on the dedicated paper from the captured dot pattern. A processor for calculating and a data communication unit for transmitting the calculated position coordinates and the like to an external device are mounted. When the user writes characters on the special paper with an anotopen or puts a check mark on the image designed on the special paper, the small camera captures the dot pattern printed on the special paper as the pen moves. The entry information such as characters and images written by the user is recognized from the continuous position coordinates calculated by the processor. Then, this entry information is transmitted from the Anotopen by the data communication unit to a nearby terminal device such as a personal computer or a mobile phone (for example, see Patent Document 1).

  Using such a system composed of an electronic pen and a computer, the applicant has proposed a technique for displaying an operation palette on the display of a computer device and reproducing a stroke written with the electronic pen (Patent Literature). 2).

Japanese Patent No. 3874498 JP 2010-191776 A

  Instead of displaying the operation palette for operating the application on the display of the computer device, for example, when the printed palette is formed on the slide created by the application, the user holds the printed material at hand, and the user can hold the printed palette at hand. Can be operated, which is convenient. However, in order to print the operation palette, the area in which the slide can be printed is limited and must be reduced. However, in order to be able to write the slide image on the printed material with the electronic pen, coordinate values are used. Applicants have found that there is a need to relatively match the two.

  A computer apparatus according to the present invention includes: an image generation unit that generates a reduced slide image obtained by reducing a slide generated by a presentation application; an operation palette image for operating a slide display; and at least the image generation unit An assigning means for assigning a coding pattern to the reduced slide image and the operation palette image, and an image generated by the image generating means and a coding pattern assigned to the assigning means are printed so as to overlap each other. Print instruction information generating means for generating print instruction information for transmitting, and transmission means for transmitting the print instruction information generated by the print instruction information generating means to a printer.

  According to this configuration, a reduced slide image obtained by reducing the slide generated by the presentation application and an operation palette image for operating the slide display are generated by the image generation unit, and at least the image generation unit is generated by the allocation unit. A coding pattern is assigned to the reduced slide image and the operation pallet image generated by the above, and the image generated by the image generation means and the coding pattern assigned to the assignment means are superimposed by the print instruction information generation means. Thus, the print instruction information for printing is generated, and the print instruction information generated by the print instruction information generation means is transmitted to the printer by the transmission means. Therefore, a printed matter on which an operation palette and a reduced slide image are printed can be obtained by printing on the printer based on the print instruction information. Since an image of the operation pallet or slide is superimposed on the coded pattern on the printed matter, predetermined processing can be performed by reading the coded pattern on the operation pallet or slide image.

  Further, the computer device according to the present invention has a printing condition setting means for selecting printing of the operation palette for operating the slide display, and when printing of the operation palette is selected by the printing condition setting means, When a slide image generated by reducing the slide generated by the presentation application and an operation palette image are generated and printing of the operation palette is not selected, the slide is generated at the same size as the slide generated by the presentation application.

  According to this configuration, it is possible to select whether or not the operation palette is printed by the printing condition setting unit, and when the printing of the operation palette is selected by the printing condition setting unit, the image generation unit can use the presentation application. A reduced slide image obtained by reducing the generated slide and an operation palette image for operating the application for the presentation are generated. If printing of the operation palette is not selected, the slide generated by the presentation application is generated. And an assigning unit assigns a coding pattern to at least the reduced slide image and the operation palette image generated by the image generating unit, or the same size slide image, and print instruction information generating unit. Is generated by image generation means Print instruction information for printing so that the image and the coded pattern assigned to the assigning means are superimposed, and the sending means sends the print instruction information generated by the print instruction information generating means to the printer. Send. For this reason, when printing on the operation palette is not selected by printing on the printer based on the print instruction information, a printed matter is obtained in which the same-size slide image and the coded pattern are superimposed. When printing of the operation palette is selected, a printed matter in which the operation palette and the reduced slide image are superimposed on the coded pattern can be obtained. And a predetermined process can be performed by reading the coding pattern on an operation palette or a slide image.

  In the computer apparatus, the assigning unit may be configured to assign a coding pattern having a different coordinate range depending on whether the operation palette is printed by the print condition setting unit. Thereby, the presence or absence of the operation palette can be recognized more clearly by reading the coded pattern and obtaining the coordinates.

The generated print instruction information is transmitted to the printer. Further, when the coded pattern on the printed matter printed by the printer is read by the electronic pen and the generated coordinate information is transmitted, the coordinate information generated by reading the coded pattern from the electronic pen is received by the receiving means. When it is determined by the drawing display means that the coordinate information received by the receiving means is an entry to the reduced image, the coordinate information is corrected and the written stroke is drawn and displayed. Therefore, even if the coordinate information obtained by reading the coded pattern on the reduced image with the electronic pen is corrected, the coordinate information is corrected, so that the stroke is drawn and displayed correspondingly to the entry on the image. .

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[Display system configuration]
FIG. 1 shows a configuration of a display system according to the present embodiment. As shown in FIG. 1, the display system according to the present embodiment includes an electronic pen 1 used by a user, a computer device 2 that receives and processes entry information from the electronic pen 1, and a print instruction from the computer device 2. The printer 3 that prints the document 6 according to the above and the projector 4 that displays the same image as the image displayed on the display of the computer device 2 on the screen 5.

  The computer device 2 has a presentation application program (also referred to as a “presentation application”) installed therein, and executes the presentation application. The computer device 2 displays an image indicating the content of the presentation application on the display and displays an image similar to the image on the screen 5 via the projector 4. Further, the computer device 2 outputs a print instruction for printing the contents of the presentation application to the printer 3, thereby creating the material 6 on which the contents of the presentation application are printed.

  FIG. 2 shows an example of the document 6 on which a page with a slide generated by the presentation application is printed. A material 6A shown in FIG. 2A is a slide printed at an equal magnification. A material 6B shown in FIG. 2B is obtained by printing an operation palette 61 in the lower portion thereof and printing a slide on the same page as the material 6A with a predetermined reduction. In both materials 6, an Anoto dot pattern (coded pattern) is printed over the entire surface. Here, the dot pattern is printed with ink containing carbon that absorbs infrared rays so that it can be read by the electronic pen 1, and an image of the slide (background image) is infrared rays so that the electronic pen 1 is not mistaken. It is printed with ink that does not contain carbon. In the case of FIG. 2B, the area where the dot pattern is printed may be limited to the operation palette 61 and the reduced background image print portion 62.

  The operation pallet 61 shown in FIG. 2B is divided into a plurality (four) of sections. Each section is printed with a dot pattern assigned thereto. In order to operate the slide display of the presentation application composed of slides of a plurality of pages, the processing performed by the computer device 2 is associated with each section 1 to 4 tapped with the electronic pen 1 and stored in the storage unit 25. The For example, in order from the left of the section of the operation palette 61 (I) display the slide of the first page, (II) display the slide of the previous page, (III) display the slide of the next page, ( IV) The process of displaying the slide of the last page is stored in the storage unit 25 in association with the section identification information for identifying the sections 1 to 4. Note that the operation palette 61 is a dedicated viewer application different from the presentation application, and may operate an application that displays a slide and stroke input by the electronic pen 1. Further, the process performed by tapping the operation palette 61 with the electronic pen 1 is not limited to the above (I)-(IV).

  When the handwritten stroke is entered in the document 6 with the electronic pen 1, the computer apparatus 2 displays the handwritten stroke superimposed on the corresponding position on the screen of the presentation application displayed on the display. The stroke is temporarily stored in the storage means 25 and projected on the screen 5 via the projector 4. Here, compared with the case where the material 6 is the material 6A type of FIG. 2A, when the material 6 is the material 6B of FIG. Therefore, the computer apparatus 2 performs processing on the coordinate data transmitted from the electronic pen 1 in consideration of the reduction ratio, corrects the coordinate data to appropriate coordinate data, and then displays the handwritten stroke on the screen of the presentation application. Display.

[Dot pattern]
Next, an Anoto dot pattern (coded pattern) formed on the material 6 will be described. FIG. 3 is a diagram illustrating the relationship between the dots of the dot pattern printed on the material 6 and the values to which the dots are converted. As shown in FIG. 3, each dot of the dot pattern is associated with a predetermined value depending on its position. In other words, each dot is associated with a value of 0 to 3 depending on which direction the top, bottom, left, or right is shifted from the reference position of the grid (intersection of the vertical line and horizontal line). The value of each dot can be further converted into a first bit value for the X coordinate and a second bit value for the Y coordinate. The position coordinates on the material 6 are determined by the combination of the information thus associated.

  FIG. 4A shows an arrangement of a certain dot pattern. As shown in FIG. 4A, 6 × 6 dots are arranged in a range of about 2 mm in length and width so that a unique pattern can be obtained regardless of where 6 × 6 dots are taken from any part of the material 6. Yes. The dot pattern formed by these 36 dots holds the position coordinates (for example, where the dot pattern is located on the material 6). FIG. 4B is a diagram in which each dot shown in FIG. 4A is converted into a value associated with the regularity shown in FIG. 3 according to the shift direction from the reference position of the lattice. This conversion is performed by the electronic pen 1 that captures an image of a dot pattern.

[Electronic pen]
Next, the electronic pen 1 will be described. As shown in FIG. 5, the electronic pen 1 includes a pen unit 104, an LED 105, a CMOS camera 106, a pressure sensor 107, a processor 108 including a CPU, a memory 109 such as a ROM and a RAM, A communication unit 111 including a real-time clock 110, an antenna, and the like, and a battery 112 are provided. The tip of the pen unit 104 is a pen point unit 103, and the user touches the pen point unit 103 of the electronic pen 1 on the material 6 and enters a stroke (handwritten stroke) of characters or the like, Tap (tap the material 6 with the pen tip 103). Here, the first contact of the pen tip 103 of the electronic pen 1 with the material 6 is referred to as pen-down, and the removal of the pen tip 103 from the contacted (contacted) state is referred to as pen-up. A trajectory written between the pen-down and pen-up of the electronic pen 1 is one stroke, and characters, figures, etc. are composed of one or a plurality of strokes.

  The battery 112 is for supplying electric power to each component in the electronic pen 1. For example, the battery 112 is configured to turn on / off the electronic pen 1 itself by attaching and detaching a cap (not shown) of the electronic pen 1. May be. The real time clock 110 transmits time information indicating the current time (time stamp) and supplies the time information to the processor 108. The pressure sensor 107 detects the pressure applied through the pen unit 104 from the pen tip unit 103 when the user writes or taps a character or mark on the material 6 with the electronic pen 1, that is, the writing pressure, and the value is detected by the processor. To 108.

  The processor 108 switches on / off the switches of the LED 105 and the CMOS camera 106 based on the writing pressure data supplied from the pressure sensor 107. That is, when the user writes characters or the like on the material 6 with the electronic pen 1, the pen pressure is applied to the pen tip portion 103, and when the pressure sensor 107 detects a writing pressure exceeding a predetermined value, the processor 108 It is determined that entry has started, and the LED 105 and the CMOS camera 106 are operated. Then, the communication unit 111 associates the pen-down information PD detected by the pressure sensor 107 with a pen ID described later, and transmits it to the computer apparatus 2 as entry information. When the user completes one stroke and moves the electronic pen 1 away from the material 6, the pressure sensor 107 detects a pen-up because no writing pressure exceeding a predetermined value is detected. Then, the communication unit 111 associates the pen-up information detected by the pressure sensor 107 with the pen ID, and transmits it to the computer apparatus 2 as entry information.

  The LED 105 and the CMOS camera 106 are attached near the pen tip portion 103 of the electronic pen 1, and an opening 102 is formed in a portion of the housing 101 that faces the LED 105 and the CMOS camera 106. The LED 105 illuminates infrared rays toward the vicinity of the pen tip portion 103 on the material 6. The region is slightly deviated from the position where the pen tip 103 contacts the material 6. The CMOS camera 106 is provided with an infrared filter that transmits infrared rays and blocks non-infrared rays. The CMOS camera 106 captures a dot pattern in an area illuminated by the LED 105 and processes image data of the dot pattern as a processor. 108. Here, since the ink material of dots reflects infrared rays, the infrared rays irradiated by the LED 105 are reflected by the dots. Therefore, the dot portion has a relatively large amount of infrared reflection, and the portion other than the dot has a relatively small amount of infrared reflection. By photographing with the CMOS camera 106, a dot area and other areas can be distinguished by providing a threshold value based on the difference in the amount of reflected infrared light. Note that the shooting area by the CMOS camera 106 is a range including a size of about 2 mm × about 2 mm as shown in FIG. 4A, and the shooting by the CMOS camera 106 is performed at regular intervals of about 50 to 100 times per second. Is called.

  The processor 108 performs X and Y coordinates (simply “positional coordinates”, “position coordinates” on the material 6 of the stroke (handwriting) to be entered by the user from the dot pattern of the image data supplied by the CMOS camera 106 during the user entry. (Also called “coordinate information”) is continuously calculated. That is, the processor 108 converts the image data of the dot pattern as shown in FIG. 4 (a) supplied by the CMOS camera 106 into the data array shown in FIG. 4 (b). The data is converted into a Y coordinate bit value, and X, Y coordinate data is calculated from the data array by a predetermined calculation method. Then, the processor 108 associates the current time (time stamp: entered time information) transmitted from the real-time clock 110, the pen pressure data, and the X and Y coordinate data. Hereinafter, these associated data are collectively referred to as “coordinate attribute information”. In addition, since the 6 × 6 dot pattern in the document 6 does not overlap in the document 6, when the user enters characters or the like with the electronic pen 1, it indicates which position in the document 6 the entered position corresponds to. It can be specified by coordinate calculation by the processor 108.

  The memory 109 stores property information such as a pen ID such as “pen01” for identifying the electronic pen 1, a pen manufacturer number, and a pen software version. Then, the communication unit 111 associates the pen ID, time information (time stamp), writing pressure data, and X and Y coordinate data, and transmits them to the computer apparatus 2 as entry information. Transmission to the computer apparatus 2 by the communication unit 111 is performed immediately and sequentially by wireless transmission such as Bluetooth (registered trademark). Here, one or a plurality of coordinate attribute information generated between the pen-down and pen-up of the electronic pen 1 and transmitted to the computer device 2 is stored as stroke information by the computer device 2. In other words, one stroke is made up of one or a plurality of X, Y coordinates (coordinate points), and the computer apparatus 2 can use one or a plurality of pieces constituting one stroke by pen down information and pen up information. Recognize coordinate attribute information. As described above, a set of coordinate attribute information generated by the electronic pen 1 when the user enters one stroke is referred to as “stroke information”. The pen tip 103 does not have ink and transmits pen pressure to the pressure sensor 107 via the pen unit 104.

[Computer device]
Next, the computer apparatus 2 will be described. The computer device 2 includes, as hardware, an antenna device capable of data communication with the electronic pen 1, a processor such as a CPU, a memory such as ROM and RAM, a display, a personal computer including a mouse and a keyboard, and the like. .

Then, the computer device 2 performs a predetermined process based on the entry information received from the electronic pen 1.

  The receiving means 22 is constituted by an antenna receiving circuit or the like, receives entry information from the electronic pen 1 and transmits it to the processing means 24. The image output unit 27 transmits an image signal according to an instruction from the processing unit 24 to the projector 4. The transmission unit 28 transmits the print instruction information of the material 6 according to the instruction from the processing unit 24 to the printer 3. The data transmission method to the printer 3 and / or the projector 4 may be wired or wireless. The display means 26 is constituted by a display or the like, and displays the contents instructed by the processing means 24.

  The storage means 25 is configured by a memory such as a hard disk, ROM, or RAM. The storage unit 25 stores the entry information received from the electronic pen 1 for each pen ID according to the processing instruction of the processing unit 24. The storage unit 25 stores in advance a presentation application program, various types of information such as design templates used in the presentation application, and a printer driver program for printing each slide created by the presentation application together with a dot pattern. is doing. In addition, the storage unit 25 stores design data of the operation palette 61 printed on the material 6, information that associates each section of the operation palette 61 with the processing performed by the computer apparatus 2, Various information used in the display system according to the present embodiment is stored such as from which dot pattern address each dot pattern is assigned when not inserted. Further, the storage unit 25 stores data of each slide (page) created by the presentation application, and a background image file serving as a background image for displaying each slide on the screen in conjunction with the material 6.

  Further, as shown in FIG. 7, the storage unit 25 stores the page number of the slide used in the presentation application, the background image file as the background image corresponding to each page, the resolution specified by the user at the time of printing, the printing The size of the background image specified by the user at the time of printing (varies depending on the paper size such as A4 and A3), the reduction rate of the background image, the coordinate range of the assigned dot pattern, and the dot pattern for each presence or absence of the operation palette Addresses are stored in association with each other. Also, as shown in FIG. 8, when printing the operation palette 61 as “present”, the correspondence between each section of the operation palette 61 and the coordinate range of the dot pattern assigned to it is stored. And the memory | storage means 25 memorize | stores the data containing the corresponding data (coordinate definition information) shown in FIG.7 and FIG.8 and the actual data of a background image file as a PPG file.

Thereby, whether or not the operation palette 61 is inserted, the same background image file is generated in advance, and the user does not insert the operation palette without being aware of which setting the background image file is generated. The printing paper created in this case and the printing paper created when inserting the operation palette 61 can be used simultaneously.
Regarding the reduction ratio of the background image, when the operation palette 61 is not inserted (“No”) with respect to the image created on the slide, the image is reduced to the same size (100%) without being reduced. Is set to be reduced to a predetermined ratio (for example, 75%). Note that the reduction ratio may be automatically calculated so that the background image (picture) fits within the paper size according to the size of the operation palette 61 inserted on the paper.
Even if the dot pattern printed on the document 6 is the same page (slide), it is set at different dot pattern addresses depending on whether the operation palette 61 is inserted or not. Is set. Here, the dot pattern address is address (address) information for specifying each section in the coordinate range partitioned by the role / function in which the dot pattern is used. As shown in FIG. 7, the dot pattern is specified for each page number to be printed in a superimposed manner depending on whether the operation palette 61 is inserted or not.

  FIG. 10 is a conceptual diagram for explaining dot pattern assignment. As shown in FIG. 10, when assigning a dot pattern to the background image file File1.png of page 1, the dots in the coordinate range belonging to the dot pattern address 15,00,01 are used for printing when the operation palette 61 is not inserted. A pattern is assigned (FIG. 10A), and dot patterns in a coordinate range belonging to different dot pattern addresses 10, 00, 01 are assigned for printing when the operation palette 61 is inserted (FIG. 10B). As described above, even in the same page, dot patterns having different dot pattern addresses and different coordinate ranges are assigned depending on whether the operation palette 61 is inserted or not. Regardless of the presence or absence of the operation palette 61, dot patterns having different dot pattern addresses and different coordinate ranges are assigned to each page.

  Furthermore, among the coordinate ranges of the dot pattern assigned when the operation palette 61 is inserted, a coordinate range to be superimposed on each section of the operation palette 61 is specified. FIG. 8 shows association data (coordinate definition information) indicating the coordinate range corresponding to each section of the operation palette 61 among the coordinate range of the assigned dot pattern. This correspondence is also stored in the storage means 25.

  As described above, the dot pattern to be printed on the material 6 is specified corresponding to each page depending on whether or not the operation palette 61 is inserted, and stored as correspondence data included in the PPG file. When the same page is printed with different print paper sizes, the dot patterns are assigned differently in the coordinate range of the same dot pattern address.

  The processing unit 24 mainly includes a printing condition setting unit 241, an image generation unit 242, a dot pattern assignment unit 243, a print instruction information generation unit 244, and a drawing display unit 245. The processing unit 24 performs various processes such as starting a presentation application and creating a slide in response to an input by the user input unit 21.

The printing condition setting unit 241 displays the printing condition setting window 7 and the like on the display unit 26, and sets the setting content input in the window as the printing condition.
The image generation unit 242 generates a background image from all slides at the time when the printing conditions are determined by the user. Further, the image generation unit 242 generates an image of the operation palette 61 based on the design data of the operation palette so as to have a size corresponding to the paper size to be printed.
The dot pattern assigning means 243 assigns a dot pattern belonging to a predetermined dot pattern address to the background image and the image on the operation palette 61 when the operation palette 61 is inserted and when the operation palette 61 is not inserted. The dot pattern may be allocated from a dot pattern database or may be generated after being generated by a predetermined algorithm. The dot pattern assignment unit 243 stores the association information (coordinate definition information) of the assigned dot pattern in the storage unit 25 together with the actual data of the background image file as a PPG file.
The print instruction information generation unit 244 determines whether or not to reduce the background image for the image generation unit 242 depending on whether the operation palette 61 is inserted or not, based on the set print conditions. The coordinate range of the dot pattern assigned for each target page and the reduction ratio (presence / absence of the operation palette 61) of the background image corresponding to the page is specified. Then, the print instruction information generation unit 244 generates a print instruction information for printing a dot pattern with ink containing carbon that absorbs infrared rays, and prints a background image with ink that does not absorb infrared rays. Is transmitted from the transmission means 28 to the printer 3.

  When the drawing display means 245 receives the entry information from the electronic pen 1, the drawing display means 245 determines the entered page and entry area based on the coordinate information included in the entry information. When the drawing display unit 245 determines that the operation palette 61 is not inserted in the document 6, the drawing display unit 245 executes a process (stroke drawing process) for drawing and displaying a handwritten stroke according to the coordinate information included in the entry information. To do. At this time, if the corresponding background image is not displayed on the display, the drawing display means 245 causes the display means 26 to display the background image in accordance with the entered page or entry area. On the other hand, when the drawing display means 245 determines that the operation palette 61 is inserted and determines that the background image print portion 62 is printed in a reduced size, it fills in the background image. The coordinate information included in the entry information is corrected so as to correspond, and a process (stroke drawing process) for drawing and displaying a handwritten stroke is executed. Further, after executing the stroke drawing process, the drawing display unit 245 associates the drawn handwritten stroke with the background image (slide) and stores it in the storage unit 25. Instead of storing the handwritten stroke in association with the background image, an image obtained by superimposing the handwritten stroke on the background image may be stored in the storage unit 25. In addition, when the drawing display unit 245 determines that the operation palette 61 is inserted and determines that it is the operation palette 61, the drawing display unit 245 displays the section of the operation palette 61 specified based on the coordinate information. Perform the associated process.

[Print processing flow]
Next, the processing will be specifically described with reference to the print processing flow shown in FIG.

  The user activates the presentation application and creates a slide for presentation. The processing unit 24 of the computer apparatus 2 creates a slide in response to an input by the user input unit 21 (step S101). A slide may be created across multiple pages.

  When printing the created slide (page), the user clicks a print button (not shown) of the presentation application or selects a print menu to input a print instruction. Then, the printing condition setting unit 241 displays the printing condition setting window 7 shown in FIG. The user performs a check in the dot print check column 71 and a printer designation from the printer designation pull-down menu 72 in the print condition setting window 7. Further, the user sets a page range to be printed by input to the all page designation print field 73 or the page designation print field 74 and the page input field 76. In addition, when changing the number of copies to be printed, the user also sets the number of copies in the copy number designation column 77. Subsequently, the user designates whether or not the operation palette 61 is to be inserted in the operation palette insertion designation field 78, checks the background image creation instruction field 79, sets the resolution in the resolution setting field 80, and then OKs. Clicking on the button 81 confirms the print instruction. Thereby, the printing condition setting unit 241 sets the setting contents as the printing conditions (step S102). The print condition setting unit 241 sets other conditions necessary for printing, such as the paper size to be printed, entered in other print condition setting windows as print conditions.

  The image generation unit 242 generates a background image file for each page from all slides (pages) (step S103). Further, the image generation unit 242 generates an image of the operation palette 61 according to the paper size set as the printing condition.

  Next, the dot pattern assigning means 243 assigns dot patterns in a coordinate range belonging to a predetermined dot pattern address to the background image and the operation palette 61 image when the operation palette 61 is inserted and when the operation palette 61 is not inserted. Assign (step S104). In this case, the dot pattern assigning unit 243 assigns a dot pattern in a different coordinate range for each page as described above, and assigns a dot pattern in a different coordinate range depending on whether or not the operation palette 61 is inserted. Then, as shown in FIG. 7, the dot pattern assignment unit 243 creates association information indicating the printing conditions for each page and the coordinate range of the assigned dot pattern, and the background image generated by the image generation unit 242. Along with the actual data of the file, it is stored in the storage means 25 as a PPG file. At this time, as shown in FIG. 8, the dot pattern assigning means 243 further specifies the coordinate range of each section in the operation palette 61 when the operation palette 61 is inserted, creates association information, and associates each page. Attached information and actual data of the background image file are stored in the storage means 25 as a PPG file.

  Subsequently, the print instruction information generation unit 244 recognizes whether or not to insert the operation palette 61 from the set print conditions (step S105). When the print instruction information generation unit 244 recognizes that the operation palette 61 is to be inserted (step S105: Yes), the image generation unit 242 sends the background image data for each page to be printed to a predetermined ratio. A further reduced image is generated, and a print image (print pattern) for printing by inserting the operation palette 61 at a predetermined position and print image information regarding a dot pattern in the corresponding coordinate range are generated (steps S106 and S107). ). On the other hand, in the process of step S105, if the print instruction information generation unit 244 recognizes that the operation palette 61 is not inserted (step S105: No), the background image data for each page to be printed is reduced. Without printing (100%), print image information relating to the dot pattern in the coordinate range corresponding to the print image (print pattern) to be printed is generated (step S107). Then, the print instruction information generating unit 244 generates a print instruction information for printing a dot pattern with ink containing carbon that absorbs infrared rays, and printing a print image (print pattern) with ink that does not absorb infrared rays, The print instruction information is transmitted from the transmission unit 28 to the printer 3 (step S108). The printer 3 receives the print instruction information and prints each material 6.

[Stroke display processing flow]
Next, the stroke display processing flow by the display system using the printed material 6 will be described with reference to FIGS. The stroke input display by the electronic pen 1 may be on the presentation application or a dedicated viewer application different from the presentation application that created the slide.

  First, the user displays a background image (slide) corresponding to an arbitrary page of the material 6 to be used on the display. When the user enters or taps characters or the like on the material 6 with the electronic pen 1, the electronic pen 1 transmits the generated entry information to the computer device 2 (step S201). Specifically, at the time of pen-down, the electronic pen 1 generates entry information in which the pen-down information PD and the pen ID are associated with each other, and transmits the generated entry information to the computer device 2. Entry information associating the coordinate attribute information including the coordinate information calculated by imaging the dot pattern and the pen ID is continuously generated and sequentially transmitted to the computer device 2. At the time of pen-up, the pen-up information PU and pen The entry information associated with the ID is generated and transmitted to the computer apparatus 2.

  In the computer apparatus 2, when the receiving unit 22 sequentially receives the entry information transmitted from the electronic pen 1, the drawing display unit 245 of the processing unit 24 stores the entry information in the storage unit 25 (step S301). Next, the drawing display unit 245 recognizes the page number of the presentation application written by the electronic pen 1 (step S302). Specifically, the drawing display means 245 refers to the coordinate definition information stored in the storage means 25 shown in FIGS. 7 and 8, and based on the coordinate information included in the entry information acquired in step S301, Recognizes the page number of the presentation application written by the electronic pen 1. At this time, the drawing display means 245 also recognizes whether or not the operation palette 61 is present, the reduction rate of the background image, and whether or not any section of the operation palette 61 has been entered. Next, the drawing display means 245 determines whether or not the operation palette 61 is inserted in the material 6 (step S303). When the drawing display unit 245 determines that the operation palette 61 is not inserted in the document 6 (step S303: No), the drawing display unit 245 determines whether the background image corresponding to the recognized page number corresponds to the coordinate information included in the entry information. A process (stroke drawing process) for drawing and displaying a handwritten stroke at the position to be executed is executed (step S304). At this time, the same image as the display of the display means 26 is projected on the screen 5 by the projector 4.

  On the other hand, when the drawing display means 245 determines that the operation palette 61 is inserted in the material 6 (step S303: Yes), the area filled in from the information recognized in step S302 is the background image print portion 62. Whether it is the operation palette 61 or other unrelated area (step S305).

  When the drawing display means 245 determines that the entered area is the background image print portion 62 (step S305: background image print portion), the drawing display means 245 corresponds to the case where the entry to the background image is not reduced. Then, the coordinate information included in the entry information is corrected (step S306), and a process of drawing and displaying a handwritten stroke at the corresponding position of the background image corresponding to the recognized page number (stroke drawing process) is executed (step S304). ). Specifically, the drawing display means 245 makes the relative coordinate value from the reference point of the background image the reciprocal of the reduction ratio, and makes the entry in the background image corresponding. At this time, the same image as the display of the display means 26 is projected on the screen 5 by the projector 4.

  When the drawing display means 245 determines that the entered area is any section of the operation palette 61 (step S305: operation palette), the drawing display means 245 performs processing specified by the section of the operation palette 61 (step S307). ). On the other hand, when the drawing display means 245 determines that the entered area is another irrelevant area (step S305: irrelevant area), the drawing display unit 245 ends without performing any processing.

  In step S304, the drawing display unit 245 executes processing for drawing / displaying a handwritten stroke (stroke drawing processing), associates the handwritten stroke with the page, and overwrites and saves the page in the storage unit 25.

  FIG. 13 is a diagram illustrating an example in which both the document 6A on which the operation palette is not printed and the document 6B on which the operation palette 61 is printed are filled with the electronic pens 1A and 1B for the same page. As shown in FIG. 13, the entry (letter “A”) to the document 6A by the electronic pen 1A corresponds to the coordinate range in the dot pattern and the page size, so that the background image is displayed on the display of the display means 26. A handwriting stroke is drawn so as to correspond to the entry to the entry, and the entry (character “I”) to the material 6B by the electronic pen 1B is also corrected because the coordinate information included in the entry information is corrected (step S306). (See), handwriting strokes are drawn so that the background image is appropriate.

[Effects of this embodiment]
As described above, according to the present embodiment, the user can select whether or not to insert the operation palette 61 when printing the slide created by the presentation application of the computer apparatus 2. Even if the slide background image is reduced and printed because the coordinate information generated by the electronic pen 1 is corrected, the background image is displayed in the same manner as when the operation palette 61 is not inserted. Handwritten strokes are drawn so that the entry is appropriate. Further, when the operation palette 61 is inserted into the printed material 6, the computer apparatus 2 can perform processing corresponding to the section by tapping the operation palette 61 with the electronic pen 1.
