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

[First embodiment]
FIG. 1 is a configuration diagram showing a schematic configuration of an information processing apparatus according to an embodiment of the present invention.

  The information processing apparatus 100 can output information handled by a screen, a file, an electronic book, or the like that is activated by an application installed in the information processing apparatus 100, and the user refers to the information. It is possible to give an input instruction to the information processing apparatus 100.

  In the present embodiment, the information processing apparatus 100 such as a portable terminal will be described as shown in the figure. However, the information processing apparatus 100 is not necessarily limited to such a device, and may be a desktop personal computer, a cellular phone, a printing device, or the like. Any device having a function of displaying on a display unit such as a panel can be applied.

  FIG. 2 is a configuration diagram illustrating a schematic configuration of hardware in the information processing apparatus 100.

  Hereinafter, the hardware configuration of the information processing apparatus 100 illustrated in FIG. 1 will be described with reference to FIG.

  In FIG. 2, reference numeral 201 denotes a CPU that comprehensively controls each device and controller connected to the system bus 204.

  Further, the ROM 202 or the external memory 211 is necessary to realize a BIOS (Basic Input / Output System) or an operating system program (hereinafter referred to as an OS), which is a control program of the CPU 201, or a function executed by each server or each PC. Various programs to be described later are stored.

  A RAM 203 functions as a main memory, work area, and the like for the CPU 201. The CPU 201 implements various operations by loading a program or the like necessary for execution of processing from the ROM 202 or the external memory 211 into the RAM 203 and executing the loaded program.

  An input controller 205 controls input from an input unit 209 such as a keyboard or a pointing device such as a mouse (not shown). A video controller 206 controls display on the display unit 210 such as a CRT display (CRT) or a liquid crystal display.

  The display unit 210 is affixed with a touch panel sheet, displays a system operation screen, and transmits the position information to the CPU 201 via the input controller 205 when a displayed key is pressed.

  Reference numeral 207 denotes a memory controller, which is stored in an external storage device (hard disk (HD)), a flexible disk (FD), or a PCMCIA card slot for storing a boot program, various applications, font data, user files, editing files, various data, and the like. Controls access to an external memory 211 such as a compact flash (registered trademark) memory connected via an adapter.

  A communication I / F controller 208 is connected to and communicates with an external device via a network (for example, the LAN 104 shown in FIG. 1), and executes communication control processing on the network. For example, communication using TCP / IP is possible.

  Note that the CPU 201 can perform display on the display unit 210 by executing outline font rasterization processing on a display information area in the RAM 203, for example. In addition, the CPU 201 enables a user instruction with a mouse cursor (not shown) on the display unit 210.

  Various programs to be described later for realizing the present invention are recorded in the external memory 211 and executed by the CPU 201 by being loaded into the RAM 203 as necessary. Furthermore, definition files and the like used when executing the program are also stored in the external memory 211, and detailed descriptions thereof will be described later.

  FIG. 3 is a flowchart showing a process for controlling the movement of the magnifier, which is executed by the information processing apparatus according to the embodiment of the present invention. Each step is executed under the control of the CPU 201.

  In step S100, a drag operation of the magnifying glass is detected by a user instruction using a mouse or the like or a user instruction by a touch operation on the display unit 210 (hereinafter described as a touch operation), and the operation position on the display unit 210 ( In step S101, it is determined whether or not the magnifier is moving a specific line of the document displayed on the display unit 210. For details of the processing, see the flowchart shown in FIG. It explains using.

  In step S102, if it is determined in step S101 that the magnifier has moved a specific line of the document, the process proceeds to step S103, and it is not determined that the specific line has been moved. Then, the process proceeds to step S100.

  In step S103, the magnifying glass is moved along a predetermined trajectory (for example, the specific row is a trajectory) with respect to the specific row determined in step S102. This will be described with reference to the flowchart shown in FIG.

  In step S104, it is detected whether or not the magnifying glass is moving with respect to the specific row determined in step S102. Details of the process will be described with reference to the flowchart shown in FIG.

  In step S105, as a result of the determination in step S104, when it is determined that the magnifying glass is moving with respect to the specific line determined in step S102, the process proceeds to step S103, and the specific line is moved. If not, the process proceeds to step S100.

  FIG. 4 is a flowchart showing processing for detecting movement of a magnifying glass in a specific row, which is executed by the information processing apparatus according to the embodiment of the present invention. Each step is executed under the control of the CPU 201.

  In step S200, it is determined whether the position with respect to the display unit 210 instructed by the touch operation is within the display area of the document. If it is determined that the position is within the display area, the process proceeds to step S201. If it is determined not to be within the display area, the process proceeds to step S203.

  As an example of the determination method in this step, the center position of the magnifying glass displayed at the position instructed by the touch operation (coordinate position in the display unit 210) and the center position before a certain time are stored in the storage medium such as the RAM 203. And the determination is made using the mutual center positions.

  FIG. 7 shows a magnifying glass information storage area 300 showing a map of a storage medium such as the RAM 203 storing these center positions.

  The magnifying glass information storage area 300 is a magnifying glass center position 301 indicating an area for storing the magnifying glass center position (coordinate position on the display unit 210), and an magnifying glass indicating an area for storing the magnifying glass center position for a predetermined time. It includes a mirror trajectory 302. The trajectory 302 stores at least one magnifying glass position as a history for a certain period of time.

  Furthermore, in this step, since it is determined whether or not the center position of the magnifying glass has moved with respect to the document display area, the display area for the document display unit 210 is stored in FIG. A document area information storage area 400 showing a map of a storage medium such as the RAM 203 is shown.

  The document area information storage area 400 stores the start point 401 of the document area that stores the start position (for example, the coordinate position with the upper left corner of the display section 210 as the origin) of the area where the lines constituting the document for the display section 210 are displayed. A document area size 402 for storing the size of the area in which the document is displayed in the X direction and the Y direction, and a document direction 403 for storing information for identifying whether the document is written vertically or horizontally. It is configured. Such information can be realized by applying an existing document analysis technique.

  Therefore, as a determination method in this step, whether the position coordinates of the magnifier acquired in step S100 are found based on the information stored in the document area information storage area 400, is within the range of the area where the document is displayed. Judgment is made depending on whether or not.

  In step S201, it is determined whether or not the trajectory of the position of the magnifying glass in the touch operation by the user is within a predetermined threshold. If it is determined that the trajectory is within the threshold, the process proceeds to step S202. If not, the process proceeds to step S203. Note that the threshold value is appropriately set in advance (for example, the average value of the distance between the center position of the line of the adjacent document and the center position of the line hit by the magnifier, Use the case where the center of the line is indicated).

  As an example of the determination method in this step, first, in obtaining the trajectory of the magnifying glass, the position of the magnifying glass stored in the trajectory 302 of the magnifying glass a predetermined time ago and the operation position where the touch operation is currently performed are determined. There are a method for calculating the trajectory of the magnifying glass and a method for calculating the trajectory of the magnifying glass from the positions of the magnifying glass before and after moving a certain distance based on the trajectory 302 of the magnifying glass.

  In determining whether the calculated magnifier position trajectory is within the threshold, the magnifier trajectory was within a certain angle (threshold) with the document based on the calculated magnifier trajectory. In this case, when the trajectory of the magnifying glass moves within a certain angle (threshold) with respect to the document and moves a certain distance or more, it can be used as a determination criterion by combining these.

  Depending on the user, after moving the enlargement frame to another row, the user suddenly performs an unintended operation such as moving the enlargement frame to the original row (for example, returning to the original row within a predetermined short time). Therefore, when such an operation occurs, the time until the enlargement frame moves to the original line is measured and stored.

  And about this judgment standard, it is also possible to set so that it may satisfy said judgment standard within this time. As for the time related to the unintended operation, for example, when an unintended operation occurs, a statistical value such as an average value may be used by sequentially using the time stored as a history.

In step S202, information indicating that the specific line is read is stored in the RAM 203, and in step S203, information indicating that the specific line is not read is stored in the RAM 203.
Display examples in this processing will be described with reference to FIGS.

  FIG. 9 shows the document displayed on the display unit 210 before the magnifier is displayed. When an instruction to display a magnifying glass is received from the user operation for the document 500, the magnifying glass is displayed at the operation position.

  Then, the user moves the magnifying glass to enlarge and display the character string existing at the position of the magnifying glass.

  FIG. 10 shows an example showing that the document 500 is started to be read using a magnifying glass. When an instruction to display the magnifying glass is received from the user operation for the document 500 shown in FIG. A magnifier 501 is displayed.

  Then, as shown in FIG. 10, the user controls the movement of the magnifying glass in the present invention by moving the magnifying glass 501. For example, the position before the magnifying glass 501 is moved is set as the pre-movement position 502. If the position of the user's touch operation is the touch operation position 503, the trajectory of the magnifying glass 501 is calculated from the pre-movement position 502 and the touch operation position 503, and if this trajectory moves within a predetermined threshold, The center position of the magnifying glass 501 or the line of the document closest to the center position is determined as having read the specific line described above.

  Furthermore, as shown in FIG. 11, assuming that a pre-movement position 504 indicating the position of the magnifying glass 501 before the magnifying glass 501 is moved and a user touch operation position is a touch operation position 505, the pre-movement position 502 and the touch operation From the position 503, the trajectory of the magnifying glass 501 is calculated, and even if this trajectory is slightly deviated from the specified line (within the aforementioned threshold), the magnifying glass 501 is moved over the specified line. Control to move.

  On the other hand, as shown in FIG. 12, assuming that a pre-movement position 506 indicating the position of the magnifying glass 501 before the magnifying glass 501 is moved and a user touch operation position is a touch operation position 507, the pre-movement position 506 and the touch operation The trajectory of the magnifier 501 is calculated from the position 507, and when the trajectory is greatly deviated from the specified row (outside the above-described threshold), the user may be referring to another row. Because it is considered, it is not determined that the specific line mentioned above is read.

  FIG. 5 is a flowchart showing processing relating to the movement control of the magnifier executed by the information processing apparatus according to the embodiment of the present invention. Each step is executed under the control of the CPU 201.

  In step S300, whether or not the document is written horizontally is determined based on the document direction 403 stored in the document area information storage area 400. If the document is determined to be written horizontally, the process proceeds to step S301. That is, if it is determined as vertical writing, the process proceeds to step S302.

  In step S301, the Y coordinate of the line specified in step S202 is set as the Y coordinate of the center position of the magnifier, and in step S302, the X coordinate of the line specified in step S202 is set as the X coordinate of the center position of the magnifier.

  In step S303, the distance to which the magnifier moves is calculated. When the Y coordinate is set in step S301, the X coordinate of the position of the magnifier and the X coordinate of the position designated by the touch operation are used. When the X coordinate is set in step S302, the Y coordinate is calculated using the Y coordinate of the position of the magnifier and the Y coordinate of the position instructed by the touch operation. Calculate the distance between them.

  In step S304, it is determined whether or not the document is horizontally written using the determination result in step S300. If the document is determined to be horizontally written, the process proceeds to step S305. If the document is not determined to be horizontally written, that is, if it is determined to be vertically written. Then, the process proceeds to step S306.

  In step S305, the Y coordinate set in step S301 is fixed and the magnifier is moved in the X coordinate direction. In step S306, the X coordinate set in step S302 is fixed and the magnifier is moved in the Y coordinate direction. Let

  When the processes of step S305 and step S306 are finished, the process proceeds to step S303.

  FIG. 6 is a flowchart showing a process related to detection of reading of a target row executed by the information processing apparatus according to the embodiment of the present invention. Each step is executed under the control of the CPU 201.

  In step S400, it is determined whether or not the position relative to the display unit 210 instructed by the touch operation is within a predetermined range with respect to the row specified in step S202, and is determined to be within the predetermined range. If not, the process proceeds to step S401. If it is not determined that the position is within the predetermined range, the process proceeds to step S403.

  As a determination method in this step, the center position 301 of the magnifying glass stored in the document area information storage area 400 is a predetermined position with respect to the coordinate position of the start point coordinates 401 of the document area of the line specified in step S202. Judgment is made based on whether or not it is within the range.

  In step S401, it is determined whether or not the trajectory of the position of the magnifier in the touch operation by the user is within a predetermined threshold value. If it is determined that it is within the threshold value, the process proceeds to step S402, and within the threshold value. If not, the process proceeds to step S403.

  As a determination method in this step, the magnifying glass trajectory obtained from the magnifying glass center position 301 and the magnifying glass trajectory 302 stored in the document area information storage area 400 is the start point of the document area of the line specified in step S202. The determination is made based on whether or not the coordinate position of the coordinate 401 is within a predetermined position range (within a threshold value). The determination method is the same as that described above in step S201.

  In step S402, information indicating that the specified target line is being read is stored in the RAM 203, and in step S403, information indicating that the specified target line is not being read is stored in the RAM 203.

[Second Embodiment]
In the first embodiment, it has been described that the movement of the magnifying glass is controlled. However, in the second embodiment, the user moves the magnifying glass by performing highlight display on the specified row. A mode for facilitating this will be described. Since the basic configuration and processing are the same as those in the first embodiment, description thereof will be omitted, and the following description will be given using the same reference numerals.

  FIG. 13 is a flowchart showing a process for controlling the highlighted display of the row related to the magnifying glass, which is executed by the information processing apparatus according to the embodiment of the present invention. Each step is executed under the control of the CPU 201.

  In step S500, highlight display is performed on the specific row read by the magnifier in steps S100 to S102.

  For example, when it is determined that the magnifying glass has been read for a specific row as shown in FIG. 10, the touch operation indicating the position is indicated from the position of the magnifying glass 501 as shown in FIG. 14. When the orbit of the magnifier up to the position 508 is on a specific line or in the vicinity, the background of the special hand line is colored to display the highlight line 509. Do.

  In step S501, if it is not determined that the position with respect to the display unit 210 instructed by the touch operation is within a predetermined range with respect to the row specified in step S500, the process proceeds to step S502.

  As a determination method in this step, the center position 301 of the magnifying glass stored in the document area information storage area 400 is a predetermined position with respect to the coordinate position of the start point coordinates 401 of the document area of the line specified in step S500. Judgment is made based on whether or not it is within the range.

  In step S502, it is determined whether or not a character string exists at a position with respect to the display unit 210 instructed by the touch operation. If it is determined that the character string exists, the process proceeds to step S503. Is not displayed, and the process proceeds to step S500.

  In step S503, highlight display is performed on a line including a character string that exists at a position relative to the display unit 210 instructed by the touch operation. However, highlighting is performed using a different color from the already highlighted line.

  In step S504, the highlighted display of the already highlighted line that is different from the highlighted line in step S503 is not displayed. The timing of the non-display is that the highlight display is performed in step S503 and the display is not performed after a predetermined time has elapsed, or the magnifying glass is applied to the row in which the highlight display is performed in step S503. After moving the same line for a predetermined distance, it is not displayed.

  As a result, it is possible to further improve usability by identifying and presenting to the user the line to which the magnifier is newly applied and the line to which the magnifier has already been applied.

  For example, as shown in FIG. 15, if the position where the magnifier is applied in FIG. 14 is the magnified position 510 as the position before the magnifier is moved, and the position designated by the user operation is the touch operation position 511. The magnifying glass 501 takes a trajectory beyond the range of a predetermined position from the originally identified line (the line to which the magnifying glass shown in FIG. Highlight the line.

  FIG. 16 shows an example in which there is no character string at the position relative to the display unit 210 instructed by the touch operation in step S503.

  Assuming that the position before the movement of the magnifier is the magnifier position 513 and the position designated by the user operation is the touch operation position 514, when there is no character string at the touch operation position 514, that is, the touch operation position 514 is the document position. FIG. 16 shows that the highlight display is not displayed when it is not in the display area.

[Third embodiment]
In the first embodiment, the invention for controlling the movement of the magnifying glass is described, and in the second embodiment, the invention for performing the highlight display to support the movement of the magnifying glass has been described. In the third embodiment, An invention that performs highlight display to support the movement of the magnifying glass while controlling the movement of the magnifying glass will be described. Since the basic configuration and processing are the same as those in the first and second embodiments, the description thereof will be omitted, and the following description will be given using the same reference numerals.

  FIG. 17 is a flowchart showing processing for supporting and controlling the movement of the magnifying glass, which is executed by the information processing apparatus according to the embodiment of the present invention. Each step is executed under the control of the CPU 201.

  In step S100 to step S102, the line read using the magnifying glass is specified. In step S500, the line is highlighted. In steps S103 to S104, the above-described specified line is displayed. Control the movement of the magnifier.

  In step S600, if it is determined in step S104 that the magnifier has moved with respect to the specific line determined in step S102, the process proceeds to step S500, and the specific line is changed. If not determined to be moving, the process proceeds to step S601.

  In step S601, it is determined whether or not there is a character string at a position relative to the display unit 210 instructed by the touch operation. If it is determined that the character string exists, the process proceeds to step S503. Is not displayed, and the process proceeds to step S602.

  In step S602, after canceling the movement control of the magnifier in step S103, the process proceeds to step S100.

  FIG. 17 shows that the movement of the magnifying glass is controlled and the highlight display is performed. The touch operation position 515 indicating the position of the touch operation before the movement of the magnifying glass 501 is set as the touch operation position. Assuming that the instructed position is the touch operation position 516, since the trajectory calculated from the touch operation position 515 and the touch operation position 516 is at a predetermined position from the specified row, the magnifying glass 501 fixes the Y coordinate. , The X coordinate is advanced, and the background of the specified row is highlighted (517).

  On the other hand, FIG. 18 shows that the row to be controlled for movement of the magnifying glass moves to another row, and further, the row to be subjected to highlight display moves to another row. Assuming that the touch operation position 518 indicating the position of the touch operation before the movement of the mirror 501 is the current touch operation position 519, the trajectory calculated from the touch operation position 518 and the touch operation position 519 is Since it is located outside the predetermined position from the specified line, the magnifying glass 501 advances the X coordinate with the Y coordinate fixed to the next specified line, and this newly specified line. Is highlighted (520).

  As described above, according to the present invention, by controlling the movement of the magnifier that magnifies and displays the text operated by the user, there is an effect that the text can be easily read by a simple operation.

  That is, when reading a document on the screen, it is possible to prevent an unintended operation of the magnifying glass due to a shake of the user's drag operation.

  For example, when a user reads a document, if the drag trajectory is unintentionally deviated from the line being read, keep the magnifying glass away from the line being read, so that another line in the middle of the document It is possible to prevent unintentional movement.
