[First embodiment]
Referring to FIG. 1, information processing apparatus 10 according to the first embodiment of the present invention includes a CPU 12. The CPU 12 is connected to the memory 14 and the touch panel 16 via the bus 30, and is further connected to the display 20 via the bus 30 and the drawing controller 18.

  In the first embodiment, a case where the information processing apparatus 10 is applied to an electronic blackboard will be described. However, the information processing apparatus 10 is applied not only to an electronic blackboard but also to various information devices or electronic devices such as a tablet terminal, a smartphone, and a PC. In response to the input, handwritten characters, figures, symbols, and the like are drawn (displayed) on the display 20.

  In the first embodiment, a case where the touch panel 16 is used as an example of the input unit will be described. However, as an input unit other than the touch panel 16, a pointing device such as a computer mouse, a touch pad, or a pen tablet is used. Also good. The information processing apparatus 10 may be provided with a hardware key such as an operation panel or a hardware keyboard as other input means.

  Returning to FIG. 1, the CPU 12 governs overall control of the information processing apparatus 10. The memory 14 is used as a work area and a buffer area for the CPU 12. The touch panel 16 detects a user's touch input and outputs data (touch coordinate data) about coordinates (touch coordinates) of a position on the display surface of the display 20 instructed by the touch input. The touch panel 16 is a general-purpose touch panel, and an arbitrary system such as an electrostatic capacity system, an electromagnetic induction system, a resistance film system, and an infrared system can be used. In the first embodiment, as the touch panel 16, a capacitive touch panel is provided on the display surface of the display 20. The drawing controller 18 includes a GPU, a VRAM, and the like, and draws various images on the screen of the display 20 under the instruction of the CPU 12.

  In the drawing apparatus 10 having such a configuration, when a user uses a touch panel 16 to input characters, figures, symbols, and the like (hereinafter sometimes referred to as “characters”) by handwriting (touch input) in the handwriting input mode. According to the handwriting input, the touch panel 16 outputs touch coordinate data corresponding to the touch position to the CPU 12. The CPU 12 draws (displays) handwritten characters on the display 20 based on the touch coordinate data output from the touch panel 16. That is, under the instruction of the CPU 12, handwritten characters and the like are drawn on the VRAM in the drawing controller 18, and image data corresponding to an image including the handwritten characters and the like drawn on the VRAM is output to the display 20. Therefore, an image including characters handwritten by the user is displayed on the display 20. Hereinafter, in this specification, an image including a handwritten character is referred to as a “handwritten image” on the premise that the user handwrites the character.

  For example, in the handwriting input mode, a screen (touch screen) 100 as shown in FIG. Button images 102 a, 102 b,... Are displayed at the left end of the touch screen 100. In addition, button images 104 a and 104 b are displayed at the center lower end portion of the touch screen 100. The button image 102a is a range button provided for changing from a handwriting tool to a range specification tool. The button image 102b is a save button provided for saving image data corresponding to a handwritten image. The button image 104a is a page turning button provided for page turning. The button image 104b is a page return button provided for page return.

  Although illustration is omitted, the touch screen 100 is for selecting a palette for selecting a line type, line color, and line width, and other tools and functions (open a new page, handwriting, eraser, cancel, etc.). The button image etc. are also displayed.

  For example, the user operates the touch panel 16 with the dedicated pen 120. However, the user can also operate with fingers. The operation (input) using the touch panel 16 includes tap (short press), slide (drag), flick, long touch (long press), etc. In the first embodiment, these are “touch input” or simply They are generically named as “input”. Further, changing from a state where the touch panel 16 is not touched to a state where the touch panel 16 is touched is referred to as touch-on (pen down), and changing from a state where the touch panel 16 is touched to a state where the touch panel 16 is not touched is referred to as touch-off (pen). Say up). For continuous touch input, that is, input by sliding or flicking, the touch panel 16 outputs touch coordinate data corresponding to the current touch position at a cycle shorter than a predetermined cycle. For example, the predetermined period is 1 to several frames, and one frame is 1/30 second or 1/60 second.

  In a general electronic blackboard, when storing image data corresponding to a handwritten image, a user may input a file name using a software or hardware keyboard.

  However, it is troublesome to display a software keyboard on the display 20 or use a hardware keyboard instead of the pen 120 when handwriting input is being performed, which is inconvenient.

  Therefore, in the first embodiment, the file name can be easily set without causing the user to perform troublesome operations.

  For example, when a meeting minutes is written on a board using an electronic blackboard, the user often first writes the agenda of the meeting as a title on the upper or left upper part of the display surface of the display 20. In addition, when the minutes data (image data) is stored after writing on the board, the agenda is likely to be input as a file name.

  Therefore, in the first embodiment, when handwriting is started in the handwriting input mode, a frame (106) for inputting a file name (title) is displayed at a predetermined position on the upper part of the display surface, and the frame (106) The handwritten character (handwritten character) is recognized at a predetermined timing and used as a file name when storing image data of a handwritten image. In this specification, the handwritten character means one handwritten character string or character string.

  3 and 4 are illustrative views showing an example of transition of the touch screen 100 when a character is handwritten on the touch screen 100 and the handwritten image is stored. FIG. 3A is an example of the touch screen 100 displayed on the display 20 when handwriting is started in the handwriting input mode. As described above, on the touch screen 100, the button images 102a, 102b,... Are displayed at the left end thereof, and the button images 104a and 104b are displayed at the center of the lower end thereof. In addition, a dotted frame 106 is displayed at the top of the touch screen 100. In the first embodiment, the frame 106 is displayed at a predetermined position and size on the touch screen 100 (display surface of the display 20). For example, as shown in FIG. 3A, a two-dimensional coordinate system (screen coordinate system) is set for the display 20, and the lower left vertex of the display surface of the display 20 is set to the origin O. The position and size of the frame 106 are determined at two points, point P1 and point P2.

  It should be noted that characters and points P1 and P2 in the coordinate system shown in FIG. 3A are only used for internal processing of the information processing apparatus 10 and are not displayed on the display 20. Further, the coordinate system need not be limited to the embodiment, and can be arbitrarily set.

  Also, as shown in FIG. 3A, the characters “file name” are displayed in the frame 106, indicating that the characters handwritten in the frame 106 can be set as the file name. However, this is an example and should not be limited. For example, the frame 106 may blink until characters are handwritten in the frame 106, or a message such as “Please input a file name in the frame” may be displayed near the frame 106.

  Therefore, the user uses the pen 120 to handwrite characters and character strings to be set as file names in the frame 106. For example, the touch screen 100 shown in FIG. 3B shows a state in which the character string “review group” is handwritten as the file name.

  Following the agenda, the user handwrites the minutes (board writing). At this time, as shown in FIG. 4A, the user handwrites characters outside the frame 106. In the first embodiment, when touch coordinate data indicating the outside of the frame 106 is input, it is determined that the handwriting of the character outside the frame 106 has started, and the character handwritten in the frame 106 at this timing Be recognized. As described above, since the range of the frame 106 is determined by the points P1 and P2, for example, if the coordinates of the points P1 and P2 are (x1, y1) and (x2, y2), they are determined by these. When an out-of-range point is indicated, an input outside the frame 106 is detected. And the character handwritten in the frame 106 is recognized based on a plurality of points detected within the range of the points P1 and P2. For example, when character recognition is executed, the display area 110 is displayed in the upper right part of the touch screen 100, and the recognition result of character recognition, that is, the recognized character (one character or character string) is displayed in the display area 110. . However, this is only an example, and a message indicating that the character recognition has succeeded may be displayed. Alternatively, the user may be notified of the success of character recognition by blinking the frame 106 or changing the color of the frame 106.

  In addition, since the character recognition of the handwritten character is already known and character recognition itself is not the essential content of this invention, description of the specific process of character recognition is abbreviate | omitted.

  If the character recognition is successful, the frame 106 and the display area 110 are erased from the touch screen 100 at an appropriate timing. Therefore, when the board of minutes is continued, the touch screen 100 as shown in FIG. After that, when the minutes of the minutes are finished and the button image 102b is touched (turned on), the save screen 200 is displayed in front of the touch screen 100 as shown in FIG.

  Referring to FIG. 5, the save screen 200 indicates that a handwritten image is saved at the top, a file name display area 202 is provided below, and further below the button image 204 a and 204b is provided. In the file name display area 202, the file name set as described above, here, “minutes. ***” is displayed as a default setting. However, “***” is an extension. The button image 204a is provided for executing saving, and the button image 204b is provided for changing a file name.

  Therefore, when the button image 204a is touched (turned on), the image data of the handwritten image is stored in a nonvolatile memory such as a hard disk or an SD card with the file name displayed in the file name display area 202. Such a non-volatile memory may be provided in the information processing apparatus 10 or may be provided in the information processing apparatus 10 in a detachable manner.

  When the button image 204b is touched, the file name is instructed to be changed. For example, a software keyboard is displayed on the display 20, and a new file name can be input using the software keyboard. However, a hardware keyboard may be used.

  3 to 5, the case where the character recognition is successful has been described. However, as shown in FIG. 6, when a symbol or a figure other than a character is written in the frame 106, the character recognition fails, For example, a message indicating that character recognition has failed is displayed. In such a case, for example, after the touch screen 100 shown in FIG. 6 is displayed for an appropriate period of time, the content handwritten in the frame 106 is erased, and a message to input a file name from the beginning is displayed in the display area 110. Is done. At this time, all touch coordinate data detected immediately before is deleted. Then, the touch screen 100 shown in FIG.

  When handwriting input is started from outside the frame 106, characters are not handwritten in the frame 106, and character recognition fails as in the above case.

  The above-described operation of the information processing apparatus 10 is realized by the CPU 12 executing an information processing program stored in the memory 14. In the first embodiment, as an example of the information processing program, a program (handwriting control processing program) for drawing and saving handwritten characters is executed. Specific processing will be described later with reference to a flowchart.

  FIG. 7 shows a memory map 40 of the memory 14. Referring to FIG. 7, memory 14 includes a program storage area 50 and a data storage area 70. The program storage area 50 stores a handwriting control processing program. The handwriting control processing program includes an input detection program 52, a drawing program 54, a display program 56, a character recognition program 58, a file name creation program 60, and a storage program 62.

  The input detection program 52 is a program for acquiring touch coordinate data output from the touch panel 16 and storing it in the data storage area 70 in time series. However, the input detection program 52 is also a program for detecting input from a hardware keyboard connected to the information processing apparatus 10 or a hardware operation panel or operation button provided in the information processing apparatus 10.

  The drawing program 54 is a program for drawing a handwritten character indicated by the touch coordinate data detected according to the input detection program 52. Specifically, when the drawing program 54 is executed, the GPU draws a handwritten image including handwritten characters on the VRAM in the drawing controller 18 under the instruction of the CPU 12. That is, image data corresponding to the handwritten image is generated. The display program 56 is a program for outputting screen data generated according to the drawing program 54 to the display 20. Therefore, the handwritten image is displayed on the display surface of the display 20.

  The character recognition program 58 is a program for recognizing a handwritten character based on touch coordinate data output from the touch panel 16 and storing the recognized character in response to handwriting input. The first embodiment is a program for recognizing handwritten characters in a frame 106 that is defined according to the frame data 76. The file name creation program 60 creates a file name using a character string (recognized character) indicated by the recognition result of the character recognition program 58, or automatically creates a file name when no recognized character is stored. It is a program to do. The storage program 62 attaches a file name created according to the file name creation program 60 or a file name changed by the user to the image data corresponding to the handwritten image, and saves it in a nonvolatile memory such as a hard disk or an SD card. It is a program to do.

  The data storage area 70 stores touch coordinate data 72, handwritten input data 74, frame data 76, recognized character data 78, image generation data 80, and the like.

  The touch coordinate data 72 is current touch coordinate data output from the touch panel 16. The handwritten input data 74 is data in which touch coordinate data for handwritten characters is stored in time series. Of the touch coordinate data output from the touch panel 16, touch coordinate data other than the touch coordinate data for handwritten characters is erased after being used for the processing of the CPU 12. That is, after it is determined that the button images 102a, 102b, 104a, and 104b displayed on the touch screen 100 have been pressed, they are deleted.

  The frame data 76 is data for defining the position and range of the frame 106. That is, the coordinate data of the points P1 and P2. The recognized character data 78 is data (text data) about a recognized character recognized and stored in accordance with the character recognition program 58. The image generation data 84 is polygon data or texture data for generating screen data for the touch screen 100. The image generation data 84 is executed by the drawing controller 18 in order to generate screen data such as the touch screen 100 and the file storage screen 200.

  In the data storage area, other data necessary for executing the information processing program is stored, and a timer (counter) and a register necessary for executing the information processing program are provided.

  FIG. 8 is a flowchart showing the handwriting control process of the CPU 12 shown in FIG. Referring to FIG. 8, when CPU 12 starts the handwriting control process, CPU 12 sets a handwriting input mode, and executes an initial process in step S1. In the initial processing, the touch coordinate data 72 and the recognized character data 78 in the data storage area 70 are deleted, the frame data 76 is set to a default value, and the image generation data 80 is read from the nonvolatile memory.

  In the next step S <b> 3, the initial touch screen 100 is displayed on the display surface of the display 20. That is, under the instruction of the CPU 12, the initial touch screen 100 as shown in FIG. 3A is displayed on the display surface of the display 20 by the drawing controller 18. At this time, a frame 106 in a predetermined range is displayed at a predetermined position on the touch screen 100 in accordance with the frame data 76, and a character string “file name” is displayed therein.

  In the subsequent step S5, a character recognition process (see FIG. 9) described later is executed. Although details will be described later, in the character recognition process, handwritten characters in the frame 106 provided on the touch screen 100 are character-recognized, and the character recognition result (recognized character) is stored as a file name.

  Subsequently, in step S7, it is determined whether or not the save button has been pressed (turned on). That is, the CPU 12 determines whether or not the touch position corresponding to the touch coordinate data input from the touch panel 16 indicates the area where the button image 102b is displayed. The same applies to the case where it is determined whether or not the button image has been pressed.

  If “NO” in the step S7, that is, if the save button is not pressed, it is determined whether or not a handwriting input is being performed in a step S9. That is, the CPU 12 determines whether or not the touch coordinate data is output from the touch panel 16 and the button images 102a, 102b, 104a, and 104b are not turned on.

  If “NO” in the step S9, that is, if handwriting input is not being performed, the process returns to the step S7 as it is. On the other hand, if “YES” in the step S9, that is, if handwriting input is being performed, the current touch coordinate data output from the touch panel 16 is written in the data storage area 70 in a step S11. That is, the touch coordinate data is stored as handwritten input data 74 in time series. In step S13, handwritten characters are drawn, and the process returns to step S7. Here, under the instruction of the CPU 12, the drawing controller 18 draws a point at the position indicated by the touch coordinate data. Therefore, during handwriting input, a line (trajectory) is drawn by a plurality of points, and a character is drawn by one or a plurality of lines.

  If “YES” in the step S7, that is, if the save button is pressed, a save process (see FIG. 10) described later is executed in a step S15, and the handwriting control process is ended.

  FIG. 9 is a flowchart of the character recognition process in step S5 shown in FIG. Hereinafter, although the character recognition process will be described, a process having the same contents as the process described in the handwriting control process of FIG. 8 will be briefly described.

  As shown in FIG. 9, when starting the character recognition process, the CPU 12 determines whether or not handwriting is being input in step S31. If “NO” in the step S31, that is, if handwriting input is not being performed, the process returns to the step S31 as it is. On the other hand, if “YES” in the step S31, the touch coordinates are stored in a step S33, a handwritten character is drawn in a step S35, and the process proceeds to a step S37.

  When handwritten input in the frame 106 is detected, the characters “file name” in the frame 106 are deleted at an appropriate timing.

  In step S37, it is determined whether or not the handwritten input is within the frame 106. Here, the CPU 12 refers to the frame data 76 to determine whether or not the touch coordinates corresponding to the current touch coordinate data are within the frame 106. If “YES” in the step S37, it is determined that the handwritten input is within the frame 106, and the process returns to the step S31 as it is.

  On the other hand, if “NO” in the step S37, that is, if the handwritten input is outside the frame 106, the handwritten character in the frame is recognized in step S39. In step S41, it is determined whether the character recognition is successful. If “YES” in the step S39, that is, if the character recognition is successful, the recognized character is displayed in the display area 110 in a step S43, the recognized character is saved as a file name in a step S45, and the character recognition process is returned. To do. In step S43, the recognition result (recognized character) is displayed in the display area 110 as shown in FIG. In step S <b> 45, the CPU 12 stores the text data corresponding to the recognized character as the recognized character data 78 in the data storage area 70.

  On the other hand, if “NO” in the step S41, that is, if the character recognition fails, an error message is displayed in the display area 110 in a step S47, and the character recognition process is returned. That is, in step S47, as shown in FIG. 6, the CPU 12 displays a message indicating that character recognition has failed.

  Note that when the process of step S47 is executed, all touch coordinate data detected immediately before is erased.

  FIG. 10 is a flowchart of the storage process in step S15 shown in FIG. As shown in FIG. 10, when the CPU 12 starts the storage process, it determines whether or not the recognized character is stored in step S61. That is, the CPU 12 determines whether the recognized character data 78 is stored in the data storage area 70.

  If “YES” in the step S61, that is, if a recognized character is stored, a file name is created using the recognized character in a step S63, and the process proceeds to a step S67. Therefore, in step S63, a file name is created by adding a character string of a period and an extension (for example, “***”) to the recognized character.

  On the other hand, if “NO” in the step S61, that is, if the recognized character is not stored, a file name is created by the automatically set character string in a step S65, and the process proceeds to the step S67. For example, in step S65, the file name is automatically created based on the numerical values for the date and time. Specifically, when a file name is created at 19:59 on September 19, 2013, a file name such as “20130919 — 1959. ***” is created. The CPU 12 acquires the date and time from the RTC provided in the information processing apparatus 10.

  In step S67, the save screen 200 is displayed on the front surface of the touch screen 100 as shown in FIG. At this time, the file name created in step S63 or S65 is displayed in the display area 202. Subsequently, in step S69, it is determined whether or not to execute storage. Here, the CPU 12 determines whether or not the button image 204a on the save screen 200 has been pressed. If “NO” in the step S69, that is, if the saving is not executed, it is determined whether or not the file name is changed in a step S71. Here, the CPU 12 determines whether or not the button image 204b on the save screen 200 has been pressed.

  If “NO” in the step S71, that is, if the file name is not changed, the process returns to the step S69 as it is to wait for an instruction to save or change the file name. On the other hand, if “YES” in the step S71, that is, if the file name is changed, the file name is changed in a step S73, and the process returns to the step S69. For example, in step S73, a software keyboard is displayed on the display 20 in an area on the front surface of the touch screen 100 where the save screen 200 is not displayed, and the file name is changed according to the user's operation. The

  If “YES” in the step S69, that is, if the saving is executed, the handwritten image is saved in a step S75, and the process returns to the handwriting control process. In step S75, the CPU 12 attaches the file name displayed in the display area 202 of the storage screen 200 to the image data corresponding to the handwritten image drawn on the touch screen 100, and stores the image data in the nonvolatile memory.

  According to the first embodiment, when image data of a handwritten image including handwritten characters is stored, a file name using handwritten characters is attached within a predetermined frame, so that there is no need to input a file name separately. You can easily give a file name.

  In addition, according to the first embodiment, when a character used for a file name is handwritten in a predetermined frame and subsequently a character is handwritten outside the frame, the character in the frame is automatically recognized. The user's hand is not bothered. In other words, it is easy to use.

  Furthermore, according to the first embodiment, the first handwritten character or character string such as the agenda can be attached as the file name, so that a file name suitable for later management and search can be attached.

  In the first embodiment, when touch input outside the frame is detected, the handwritten character in the frame is recognized. However, the present invention is not limited to this. For example, when moving to a page (page advance, page back) different from the current page or opening a new page, the handwritten characters in the frame may be recognized. Even in such a case, characters are recognized in accordance with a normal operation such as page-forwarding, page-returning, or opening a new page, so that the user's hand is not bothered. In this case, since the characters in the frame are recognized at the timing of displaying another page, there is no need to start writing characters from within the frame. Therefore, for example, it suffices if characters are written in the frame before the page is sent, and the degree of freedom in writing the file name is increased.

  In such a case, as shown in FIG. 11, a part of the character recognition process shown in FIG. 9 is changed. In brief, when the CPU 12 draws a handwritten character in step S35, the CPU 12 determines whether to display another page in step S37a. Here, the CPU 12 determines whether the button 104a or the button 104b has been pressed or an instruction to open a new page has been issued.

  If “NO” in the step S37a, that is, if another page is not displayed, the process returns to the step S31 as it is. On the other hand, if “YES” in the step S37a, that is, if another page is displayed, the handwritten characters in the frame are recognized in step S39.

  When an instruction to display another page is given, the touch screen 100 for the other page is displayed on the display 20 after the process of step S5 shown in FIG.

In the first embodiment, when a handwriting input outside the frame or an instruction to display another page is input, the handwritten character in the frame is recognized. When a predetermined time (for example, 30 seconds to 1 minute) has passed, the handwritten character in the frame may be recognized.
[Second Embodiment]
The information processing apparatus 10 according to the second embodiment is the same as the information processing apparatus 10 according to the first embodiment except that the position and size of the frame 106 can be arbitrarily specified within the range of the touch screen 100. Will be described, and redundant description will be omitted. In the information processing apparatus 10 of the second embodiment, since the user designates the frame 106, the frame 106 is not displayed on the initial touch screen 100 displayed when the handwriting control process is started.

  As shown in FIG. 12A, in the second embodiment, a button image 108a is further displayed below the button images 102a, 102b,... The button image 108a is used for handwritten input of characters used for the file name. Specifically, as shown in FIG. 12A, when the button image 108a is touched, it is instructed to hand-write characters used for the file name, and as shown in FIG. The frame 106 can be specified using. As can be seen from FIG. 12B, when the pen 120 is dragged to move diagonally downward to the right, the frame 106 is designated (set) by the touch-on position and the touch-off position, and the frame is displayed on the touch screen 100. 106 is displayed. At this time, the button image 108b is displayed on the touch screen 100 instead of the button image 108a. The button image 108b is used for character recognition of handwritten characters in the frame 106 and storing the recognized characters.

  In the second embodiment, the conversion button 108b is displayed instead of the file name button 108a. However, the conversion button 108b may be additionally displayed.

  When the user designates the frame 106, the user handwrites characters in the frame 106 as shown in FIG. However, since the characters in the frame 106 are recognized when the button image 108b is pressed, it is not necessary to hand-write the characters in the frame 106 immediately after the frame 106 is designated. When the button image 108b is pressed after handwriting a character in the frame 106, the handwritten character in the frame 106 is recognized as shown in FIG. 13B, and the recognition result is displayed in the display area 110. Note that the case where the character recognition fails is the same as the case shown in the first embodiment.

  FIG. 14 is a flowchart showing the handwriting control process of the CPU 12 in the second embodiment. Hereinafter, although the handwriting control process shown in FIG. 14 will be described, the same process as the process described in the handwriting control process of the first embodiment will be briefly described.

  As shown in FIG. 14, when starting the handwriting control process, the CPU 12 executes an initial process in step S111. However, the frame data 76 is also deleted here. Next, in step S113, the initial touch screen 100 is displayed on the display 20. However, on the initial touch screen 100, the frame 106 is not displayed, but the file name button, that is, the button image 108a is displayed below the button images 102a, 102b,.

  In a succeeding step S115, it is determined whether or not the file name button is pressed. If “NO” in the step S115, that is, if the file name button is not pressed, the process proceeds to a step S123 as it is.

  On the other hand, if “YES” in the step S115, that is, if the file name button is pressed, a conversion button is displayed in place of the file name button in a step S117, and a frame designation process described later (FIG. 15) is performed in a step S119. In step S121, a character recognition process (see FIG. 16), which will be described later, is executed, and then the process proceeds to step S123.

  In step S123, it is determined whether the save button has been pressed. If “NO” in the step S123, it is determined whether or not a touch input is being performed in a step S125. If “NO” in the step S125, the process returns to the step S115 as it is. On the other hand, if “YES” in the step S125, the touch coordinates are stored in a step S127, a handwritten character is drawn in a step S129, and the process returns to the step S115.

  If “YES” in the step S123, a storing process is executed in a step S131, and the handwriting control process is ended. The storage process in step S131 is the same as that described with reference to FIG. 10 in the first embodiment, and thus a duplicate description is omitted.

  FIG. 15 is a flowchart of the frame designation process in step S119 shown in FIG. As shown in FIG. 15, when starting the frame designation process, the CPU 12 determines whether or not the start point is designated in step S131. That is, the CPU 12 determines whether or not the touch coordinate data is not output from the touch panel 16 and the touch coordinate data is output.

  If “NO” in the step S131, that is, if the start point is not designated, the process returns to the same step S131 as it is. On the other hand, if “YES” in the step S131, that is, if the start point is instructed, the coordinates of the instructed start point are stored in a step S133. Here, the coordinate data of one point in the frame data 76 is stored. In the next step S135, it is determined whether an end point has been designated. Here, the CPU 12 determines whether or not the state where the touch coordinates are output from the touch panel 16 is changed to the state where the touch coordinate data is not output.

  If “NO” in the step S135, that is, if the end point is not instructed, the frame 106 defined by the start point and the current touch position is displayed on the touch screen 100 in a step S137, and the process returns to the step S135. On the other hand, if “YES” in the step S135, that is, if an end point is designated, the coordinates of the designated end point are stored in a step S139. Here, the coordinate data of other points in the frame data 76 is stored. Therefore, the frame data 76 is determined (designated). In step S141, the frame 106 defined by the start point and the end point is displayed, and the process returns to the handwriting control process.

  FIG. 16 is a flowchart of the character recognition process in step S121 shown in FIG. Since this character recognition process is the same as that described with reference to FIG. 9 in the first embodiment, a duplicate description is omitted. As shown in FIG. 16, in the character recognition process of the second embodiment, step S37b is provided instead of step S37. That is, when the CPU 12 draws the handwritten image in step S35, the CPU 12 determines whether or not the conversion button is pressed in step S37b.

  If “NO” in the step S37b, that is, if the conversion button is not pressed, the process returns to the step S31 as it is. Therefore, the handwriting of characters is continued. On the other hand, if “YES” in the step S37, that is, if the conversion button is pressed, the handwritten characters in the frame 106 are recognized in step S39.

  According to the second embodiment, the user designates a frame, recognizes the handwritten characters in the frame at the timing when the conversion button is pressed, and uses them for the file name. The timing, position, and range to be set can be arbitrarily set.

  In addition, according to the second embodiment, as in the first embodiment, when saving image data of a handwritten image including handwritten characters, a file name using handwritten characters in a predetermined frame is attached. There is no need to input a separate file name, and the file name can be easily assigned.

  In the second embodiment, the characters in the frame are recognized when the conversion button is pressed. However, the present invention is not limited to this. For example, when a character is handwritten in the frame immediately after the frame is specified and the character in the frame is recognized, the character is handwritten in the frame as in the first embodiment. The character may be recognized at a timing when handwriting is performed outside the frame or an instruction to display another page is given.

In addition, immediately after designating a frame, when a character is handwritten in the frame and the character in the frame is recognized, the state in which no handwriting input is made in the frame is a predetermined time (for example, When 30 seconds to 1 minute) elapses, the handwritten characters in the frame may be recognized.
[Third embodiment]
The information processing apparatus 10 according to the third embodiment does not display the frame 106 on the touch screen 100 and does not detect the handwritten input, and when the time during which this state continues exceeds a predetermined time, Since the information processing apparatus 10 is the same as the information processing apparatus 10 of the first embodiment except that all handwritten characters input by handwriting are recognized, different contents will be described and redundant description will be omitted.

  FIG. 17A shows an example in which the touch screen 100 is displayed and characters are handwritten. When the user has handwritten characters and no handwritten input has passed for a predetermined time (for example, 30 seconds to 1 minute), all handwritten characters handwritten so far are recognized. When the character recognition is successful, the recognition result of the character recognition is displayed in the display area 110 as shown in FIG.

  The information processing apparatus 10 of the third embodiment is the same as the handwriting control process (FIG. 8) of the first embodiment except that the frame 106 is not displayed on the touch screen 100 and a part of the character recognition process is different. . Therefore, here, the character recognition processing of the third embodiment will be described with reference to the drawings. However, the same processing as already described will be briefly described.

  FIG. 18 is a flowchart showing character recognition processing in the third embodiment. As shown in FIG. 18, when starting the character recognition process, the CPU 12 resets the timer in step S30. That is, the timer value is set to 0. As a timer, a timer provided in the data storage area 70 can be used. In the next step S31, it is determined whether or not handwriting is being input. If “YES”, the touch coordinates are stored in step S33, handwritten characters are drawn in step S35, and the process returns to step S30.

  On the other hand, if “NO” in the step S31, the timer is counted up in a step S32, and it is determined whether or not the count value exceeds a predetermined time in a step S34. If “NO” in the step S34, that is, if the count value does not exceed the predetermined time, it is determined that the predetermined time has not elapsed since the handwritten input is lost, and the process returns to the step S31. On the other hand, if “YES” in the step S34, that is, if the count value exceeds a predetermined time, it is determined that the predetermined time has passed since the handwriting input is lost, and all handwritten characters are recognized in a step S39a.

  Since the processing after step S41 is the same as the character recognition processing of the first embodiment, a duplicate description is omitted.

  According to the third embodiment, when handwritten input is continued for a predetermined time after handwritten input, all the handwritten characters input so far are recognized as characters. You can easily add file names without bothering you.

  For example, in a meeting, if the agenda is handwritten on the electronic blackboard and then a predetermined time elapses before the discussion starts, the file used to save the minutes data that was handwritten earlier Can be used for names.

In the third embodiment, unlike the first and second embodiments, no frame is displayed and character recognition is started when a predetermined time has elapsed. You may display that it is in text, change the color of a handwritten character, or blink a handwritten character.
[Fourth embodiment]
The information processing apparatus 10 of the fourth embodiment designates the frame 106 so as to surround the handwritten character, and recognizes the handwritten character in the frame 106 when storing the image data of the handwritten image. Since the second embodiment is the same as the second embodiment, different contents will be described, and redundant description will be omitted.

  In the fourth embodiment, as in the second embodiment, when the handwriting control process is started, the frame 106 is not displayed. Accordingly, as shown in FIG. 19A, a handwritten image is drawn on the touch screen 100 where the frame 106 is not displayed. When the user presses the range button (button image 102a) after the handwriting input has advanced to some extent, the frame 106 can be designated using the pen 120 as shown in FIG. In the fourth embodiment, the frame 106 is designated using the pen 120 so as to surround the handwritten character. The method for designating the frame 106 is the same as in the second embodiment.

  Subsequently, as shown in FIG. 20, when the user presses the save button (button image 102b), the handwritten characters in the frame 106 are recognized. Then, a file name is created using the recognition result, and a storage screen 200 similar to that shown in FIG. 5 is displayed on the front surface of the touch screen 100. The storage process is the same as in the first embodiment.

  Therefore, for example, in the fourth embodiment, as in the case of writing the minutes of the minutes, the characters are handwritten and the data about the minutes (image data of the handwritten image) is saved to the file name. The handwritten character to be used can be selected (designated).

  In the fourth embodiment, when the frame 106 is designated, the data is saved immediately. However, if the handwriting input is continued without saving the data, the designated frame 106 is canceled (erased). ) So that it can be specified again.

  FIG. 21 is a flowchart showing the handwriting control process of the CPU 12 in the fourth embodiment. Hereinafter, the handwriting control process of the fourth embodiment will be described, but the same process as the already described process will be briefly described.

  As shown in FIG. 21, when starting the handwriting control process, the CPU 12 executes an initial process in step S201. However, the frame data 76 is also deleted here. Next, an initial touch screen 100 is displayed on the display 20 in step S203. However, the frame 106 is not displayed.

  In a succeeding step S205, it is determined whether or not handwriting is being input. If “NO” here, the process returns to the same step S205. On the other hand, if “YES” in the step S205, the touch coordinates are stored in a step S207, and handwritten characters are drawn in a step S209.

  In step S211, it is determined whether the range button has been pressed. That is, the CPU 12 determines whether or not the button image 102a has been touched. If “NO” in the step S211, that is, if the range button is not pressed, the process returns to the step S205. On the other hand, if “YES” in the step S211, that is, if the range button is pressed, a frame specifying process is executed in a step S213. That is, the frame data 76 is stored in the data storage area 70 in accordance with a user instruction. As described above, the frame designation process is the same as that described with reference to FIG. 15 in the second embodiment, and thus detailed description thereof is omitted.

  In step S215, it is determined whether the save button has been pressed. That is, the CPU 12 determines whether or not the button image 102b is touched. If “NO” in the step S215, that is, if the save button is not pressed, the process returns to the same step S215 and waits for the save button to be pressed. On the other hand, if “YES” in the step S215, that is, if the save button is pressed, a character recognition process (FIG. 22) described later is executed in a step S217, a save process is executed in a step S219, and handwriting control is performed. The process ends. As described above, the storage process in step S219 is the same as that described with reference to FIG. 10 in the first embodiment, and thus detailed description thereof is omitted.

  FIG. 22 is a flowchart of the character recognition process in step S217 shown in FIG. Since this character recognition processing is the same as the contents of steps S39 to S47 described with reference to FIG. 9 in the first embodiment, detailed description thereof is omitted. In the fourth embodiment, steps S31 to S37 are omitted because character recognition is performed after a frame is specified for characters that have been handwritten.

  According to the fourth embodiment, after handwriting a character, the user can specify a desired character from all handwritten characters and use it as a file name when saving image data of a handwritten image. Because you can, you can easily name the file using handwritten characters.

  In the fourth embodiment, the save button is operated after the frame is specified. However, after the frame is specified, a predetermined time (for example, 30 seconds to 1 minute) has passed without any operation. In such a case, the saved screen may be displayed by automatically recognizing handwritten characters in the frame.

  In addition, the specific numerical values, coordinate system, screen configuration, and the like given in the above-described embodiments are examples, and can be appropriately changed according to actual products.
