Description

The present invention relates to an information processing apparatus, an information processing method, and a program capable of realizing appropriate calibration even when a user performs a rough or incorrect operation.

  Recently, there is an increasing demand for information processing apparatuses including a touch panel laminated on a liquid crystal display. Due to the nature of touch panels used in information processing devices, an error occurs between the user's operation position (contact position of a finger, etc.) and detection coordinates due to changes over time, etc., and calibration is appropriately performed to correct the error. There is a need to do.

  As an information processing apparatus capable of performing such touch panel calibration, the following is known. That is, the information processing apparatus confirms that each difference between the x-coordinate data and the y-coordinate data generated by the touch operation repeatedly performed on points other than the center of the touch panel is within an allowable range. The error between the coordinate data actually measured with respect to the touch-operated point and the logical coordinate data is reduced (see, for example, Patent Document 1).

The removable medium 31 can also store various data such as image data stored in the storage unit 19 in the same manner as the storage unit 19.

FIG. 2 is a functional block diagram showing a functional configuration for executing the calibration process among the functional configurations of the information processing apparatus 1.
The calibration process refers to the following process that is started when the user presses the calibration button of the input unit 17. That is, the calibration process is to calculate a deviation amount between a touch position where a touch operation is performed a plurality of times on the touch panel stacked on the display screen of the output unit 18 and the display screen, and to determine the calculated deviation amount. A series of processing until the calibration value is calculated and stored based on the result.
Here, the touch operation refers to an operation of touching or approaching an object (such as a user's finger or a touch pen) on the touch panel. Details of the touch panel will be described later.
When a touch operation is performed after execution of the calibration process, the information processing apparatus 1 recognizes the position of the touch operation based on the calibration value calculated by the calibration process, and performs various processes according to the position. Run.

In the CPU 11, when the execution of the calibration process is controlled, the display control unit 41, the input operation reception unit 42, the position information acquisition unit 43, the maximum value / minimum value determination unit 44, and the deviation amount calculation unit 45. Then, the deviation amount determination unit 46, the control unit 47, and the calibration value calculation unit 48 function.
In one area of the storage unit 19, a position information storage unit 51 and a correction information storage unit 52 are provided.

  The display control unit 41 performs control to display a captured image captured by the imaging unit 16 or a predetermined image (such as an icon 101a to an icon 101d in FIG. 4 described later) so as to be included in the display screen of the output unit 18. Run.

  In the present embodiment, a part of the input unit 17 is configured as a touch panel as described above. The touch panel is stacked on the entire display screen of the output unit 18 and detects the coordinates of the position where the touch operation is performed. The input unit 17 supplies the coordinates of the detected position to the position information acquisition unit 43 via the input operation reception unit 42.

The input operation accepting unit 42 accepts a touch operation on the touch panel of the input unit 17 as one of the input operations on the input unit 17. Specifically, the input operation receiving unit 42 receives a plurality of coordinates of a position where a touch operation has been performed on the touch panel of the input unit 17 and notifies the position information acquisition unit 43 of the coordinates of the received position.
The input operation receiving unit 42 counts the number of times that the touch operation performed on the touch panel of the input unit 17 is received. The input operation reception unit 42 notifies the control unit 47 of the counting result, that is, the number of times the touch operation is received.

  The position information acquisition unit 43 is used to calculate a calibration value of a calibration value calculation unit 48 to be described later based on the coordinates of the position received by the input operation reception unit 42, that is, the coordinates of the position where the touch operation has been performed. Position information is acquired. Specifically, the input operation reception unit 42 acquires information including A / D conversion values based on the coordinates of the position where each touch operation is performed as position information, and the position information acquisition unit 43 acquires the acquired position. The information is stored in the position information storage unit 51 of the storage unit 19, and the maximum / minimum value determination unit 44 and the deviation amount calculation unit 45 are notified that the position information has been acquired.

The maximum value / minimum value determination unit 44 determines whether the maximum value or the minimum value indicated by the position information acquired by the position information acquisition unit 43 is within a predetermined range.
Here, the maximum value and the minimum value are the maximum value and the minimum value in the x-axis direction of the display screen of the output unit 18 and the maximum value and the minimum value in the y-axis direction of the display screen of the output unit 18. Broadly divided.
That is, in the present embodiment, calibration is performed on the coordinates of the touch panel corresponding to the positions of the four corners of the display screen of the output unit 18.
In this case, the x coordinate of the touch panel corresponding to the upper left or lower left position of the display screen of the output unit 18 is the minimum value in the x axis direction. The x coordinate of the touch panel corresponding to the upper right or lower right position of the display screen of the output unit 18 is the maximum value in the x axis direction.
On the other hand, the y coordinate of the touch panel corresponding to the upper left or upper right position of the display screen of the output unit 18 is the minimum value in the y axis direction. Further, the y coordinate of the touch panel corresponding to the lower left or lower right position of the display screen of the output unit 18 is the maximum value in the y-axis direction.
The maximum value / minimum value discriminating unit 44 obtains four values of the maximum value and the minimum value in the x-axis direction and the maximum value and the minimum value in the y-axis direction from the position information acquired by the position information acquisition unit 43, respectively. Recognize and individually determine whether each of these four values is within a predetermined range.
The maximum value / minimum value determination unit 44 notifies the control unit 47 of the determination results of these four values.

The deviation amount calculation unit 45 recognizes each coordinate when a plurality of touch operations are performed on the same target location (the positions of the four corners of the display screen) from the position information acquired by the position information acquisition unit 43. For each of these coordinates, a deviation amount from a predetermined reference coordinate is calculated.
Specifically, in the present embodiment, the positions of the four corners of the display screen are adopted as the same target location, and two touch operations are performed on the positions of the four corners.
Accordingly, two values are obtained for each of the maximum value and the minimum value in the x-axis direction and the maximum value and the minimum value in the y-axis direction.
Therefore, the deviation amount calculation unit 45 calculates the difference of the maximum value in the x-axis direction twice, the difference of the minimum value in the x-axis direction twice, the difference of the maximum value in the y-axis direction twice, and the difference in the y-axis direction. Four differences, such as a difference between two minimum values, are calculated as deviation amounts.
The deviation amount calculation unit 45 notifies the deviation amount determination unit 46 of the calculated deviation amount.

The deviation amount determination unit 46 determines whether or not the deviation amount calculated by the deviation amount calculation unit 45 is within a predetermined predetermined deviation amount allowable range. Specifically, the deviation amount determination unit 46 trusts the deviation amounts at the predetermined positions (the four corner positions of the display screen that are the same target location) calculated by the deviation amount calculation unit 45 for calibration processing. It is discriminated whether or not it is within a predetermined deviation amount allowable range sufficient for.
The deviation amount determination unit 46 notifies the control unit 47 of the determined determination result.

The control unit 47 controls whether or not to calibrate the calibration value calculation unit 48 based on the determination result determined by the deviation amount determination unit 46. Specifically, when the control unit 47 receives a determination result indicating that the shift amount determined by the shift amount determination unit 46 is within the shift amount allowable range, the operation of the calibration value calculation unit 48 starts. To be controlled. Specifically, the control unit 47 notifies the calibration value calculation unit 48 of the determination result that the shift amount determined by the shift amount determination unit 46 is within the shift amount allowable range, thereby calculating the calibration value. The operation of the unit 48 is started.
On the other hand, the control unit 47 prohibits the operation of the calibration value calculation unit 48 when receiving a determination result that the shift amount determined by the shift amount determination unit 46 is outside the shift amount allowable range. To control. In this case, the control unit 47 controls the display control unit 41 to display a warning that the calibration has failed on the display screen of the output unit 18.
Further, the control unit 47 determines whether the touch operation is reception of the first touch operation described later, that is, how many times the touch operation is received, according to the number of times the touch operation is received by the input operation reception unit 42. Determine whether or not.

  The calibration value calculation unit 48 receives the notification of the determination result that the deviation amount is within the deviation amount allowable range, and the coordinates of the position where the touch operation accepted by the input operation acceptance unit 42 has been made are used as a trigger. Based on this, a calibration value is calculated. Specifically, the calibration value calculation unit 48 acquires the position coordinates acquired by the position information acquisition unit 43 from the position information storage unit 51, and calculates the average value of the acquired position coordinates as a calibration value. . The calibration value calculation unit 48 stores the calculated calibration value in the correction information storage unit 52.

Next, a calibration process executed by the information processing apparatus 1 having the functional configuration shown in FIG. 2 will be described with reference to FIG.
FIG. 3 is a flowchart for explaining the flow of calibration processing executed by the information processing apparatus 1 of FIG. 1 having the functional configuration of FIG.

  The calibration process is a process (may be executed in parallel) that is executed independently of a shooting process (not shown) performed by the user pressing the shutter button. The process is started when the calibration button is pressed, and the following processing is repeatedly executed.

  In step S11, the control unit 47 determines whether or not the first touch operation is accepted. Here, the acceptance of the first touch operation refers to a state in which the touch operation is accepted once for the coordinates of the touch panel corresponding to the positions of the four corners of the display screen of the output unit 18. Specifically, in the present embodiment, a state in which a touch operation is received once at a position appropriate for calibration of the input unit 17 corresponding to the four corners of the display screen of the output unit 18 (hereinafter, “ This is called “unit touch operation”. If the touch operation is accepted after the first time, it is determined as NO in Step S11, and the process proceeds to Step S12.

  In step S <b> 12, the control unit 47 executes control for identifying and displaying the failed touch operation position on the display screen of the output unit 18 via the display control unit 41. The identification display of the failed touch operation position by the display control unit 41 will be described with reference to FIGS. If the first touch operation is accepted, it is determined as YES in step S11, and the process proceeds to step S13.

  In step S <b> 13, the control unit 47 performs control to display the normal touch position on the display screen of the output unit 18 via the display control unit 41. The display of the normal touch position by the display control unit 41 will be described with reference to FIG.

In step S14, the input operation reception unit 42 receives a touch operation by the user. When the input operation accepting unit 42 accepts the first touch operation, that is, when it is determined to be YES in step S11, the input operation accepting unit 42 performs calibration a plurality of times for all the locations out of the positions suitable for calibration. The touch operation of the application is accepted.
On the other hand, when the input operation accepting unit 42 accepts touch operations after the first time, that is, when it is determined NO in Step S11, the amount of deviation is out of the positions suitable for calibration. A calibration touch operation is accepted for a location that is determined to be outside the allowable deviation range.

  In step S15, the position information acquisition unit 43 acquires the coordinates of the position where the first touch operation has been performed based on the touch operation received in step S14. At this time, the position information acquisition unit 43 accumulates and counts the number of times the position coordinates are acquired.

  In step S16, the position information acquisition unit 43 determines whether the coordinates of the position where the touch operation acquired in step S15 is performed are the coordinates of the position where the last touch operation was performed. The position where the last touch operation has been performed refers to a position where the last touch operation for which the position coordinates have not been acquired in step S15 is performed among the positions appropriate for calibration of the input unit 17 among the unit touch operations. . Specifically, in the present embodiment, the touch operation is accepted once for all the positions suitable for calibration of the input unit 17 corresponding to the four corners of the display screen of the output unit 18. It is determined whether or not. If the acquired coordinates of the position where the touch operation has been performed are not the coordinates of the position where the last touch operation has been performed, it is determined as NO in Step S16, and the process returns to Step S14 again. That is, until the coordinates of the position where the last touch operation has been performed are obtained, the determination process of step S14 to step S16: NO is repeatedly performed, and the calibration process enters a standby state. If the acquired coordinates of the position where the touch operation was performed are the coordinates of the position where the last touch operation was performed, it is determined as YES in Step S16, and the process proceeds to Step S17.

  In step S17, the maximum value / minimum value determination unit 44 determines whether the maximum value and the minimum value of the coordinates of the position where the touch operation acquired in step S15 is performed are within a predetermined range. If it is determined that either the maximum value or the minimum value of the coordinates of the position where the touch operation has been performed is not within the predetermined range, it is determined NO in step S17, and the process proceeds to step S18. .

In step S <b> 18, the control unit 47 controls the display control unit 41 to display a calibration failure warning on the display screen of the output unit 18. The calibration failure warning display is determined by the maximum value / minimum value determination unit 44 that the maximum value and the minimum value of the coordinates of the position where the touch operation acquired in step S15 is not within the predetermined range. In this case, the coordinates of the position where the touch operation is performed are not reliable values, and a display is made to warn the user that the touch operation is invalid. Specifically, the display control unit 41 controls the display of the output unit 18 to display “input touch operation is invalid” on the display screen, so that the touch operation input to the user can be redone. Prompt.
If it is determined that the maximum value and minimum value of the coordinates of the acquired touch operation position are within the predetermined range, YES is determined in step S17, and the process proceeds to step S19.

  In step S <b> 19, similarly to step S <b> 13, the control unit 47 executes control for displaying the normal touch position on the display screen of the output unit 18 via the display control unit 41. The display of the normal touch position by the display control unit 41 will be described with reference to FIG.

  In step S20, as in step S14, the input operation reception unit 42 receives a touch operation by the user.

  In step S21, as in step S15, the position information acquisition unit 43 acquires the coordinates of the position where the second touch operation has been performed based on the touch operation received in step S20. At this time, the position information acquisition unit 43 accumulates and counts the number of times the position coordinates are acquired.

  In step S22, as in step S16, the position information acquisition unit 43 determines whether or not the coordinates of the position where the touch operation acquired in step S21 is performed are the coordinates of the position where the last touch operation was performed. . If the acquired coordinate of the position where the touch operation is performed is not the coordinate of the position where the last touch operation was performed, it is determined as NO in Step S22, and the process returns to Step S20 again. That is, until the coordinates of the position where the last touch operation has been performed are obtained, the determination process in steps S20 to S22: NO is repeatedly performed, and the calibration process is in a standby state. If the acquired coordinates of the position where the touch operation has been performed are the coordinates of the position where the last touch operation has been performed, it is determined as YES in Step S22, and the process proceeds to Step S23.

  In step S23, the shift amount calculation unit 45 calculates the shift amount between the coordinates of the position where the first touch operation is performed and the coordinates of the position where the second touch operation is performed. Specifically, the deviation amount calculation unit 45 includes the coordinates of the position where the first touch operation acquired in step S15 in the same place and the position where the second touch operation acquired in step S21 is performed. The difference of coordinates is calculated respectively.

  In step S24, the deviation amount determination unit 46 determines whether the deviation amount calculated in step S23 is within a predetermined range, that is, within a deviation amount allowable range. Specifically, the deviation amount determination unit 46 has the coordinates of the position where the first touch operation is performed and the coordinates of the position where the second touch operation are performed within the deviation amount allowable range sufficient for use of calibration. It is determined whether or not. If it is determined that the calculated deviation amount is not within the predetermined range, ie, the deviation amount allowable range, NO is determined in step S24, and the process returns to step S18. That is, until the calculated deviation amount, that is, until the deviation amount falls within the deviation amount allowable range, the determination process of step S11 to step S24: NO is repeatedly executed, and the calibration process enters a standby state. When the calculated deviation amount is within the predetermined range, that is, within the deviation amount allowable range, it is determined as YES in Step S24, and the process proceeds to Step S25.

  In step S25, the calibration value calculation unit 48 calculates the average value of the first and second coordinates as a calibration value. Specifically, the calibration value calculation unit 48 calculates the average based on the coordinates of the position where the touch operation is acquired in step S15 and the coordinates of the position where the touch operation is acquired in step S21. The value is calculated as a calibration value.

  In step S26, the calibration value calculation unit 48 stores the calibration value calculated in step S25 in the correction information storage unit 52. The information processing apparatus 1 can perform calibration based on the calibration value stored in the correction information storage unit 52. When this process ends, the calibration process ends.

Further, the calibration process of FIG. 3 will be specifically described below with reference to FIG.
FIG. 4 shows an example of the display screen of the display of the output unit 18 for displaying the normal touch position during the calibration process of FIG.

In FIG. 4, cross-shaped icons (touch point instruction images) 101 a, 101 b, 101 c, and 101 d are arranged in the vicinity of the four corners of the display screen of the output unit 18.
As described above, when it is determined in step S11 that the first touch operation is accepted, that is, when it is the first touch operation, the display control unit 41 displays the display on the output unit 18. The normal touch position is displayed on the screen.
As shown in FIG. 4, the normal touch position display means that icons 101 a, 101 b, 101 c, and 101 d that indicate locations where a touch operation is necessary for executing calibration are displayed to the user on the display of the output unit 18. To display on the display screen. When the user performs a touch operation on each icon 101a, 101b, 101c, 101d displayed on the display screen of the output unit 18, the coordinates of the position where the touch operation has been performed are acquired (step S15). . In the present embodiment, the icons 101a, 101b, 101c, and 101d are displayed on the display screen of the output unit 18 at a time. However, the present invention is not limited to this. You may make it display one by one in the order which decided clockwise etc. at each corner of the display screen.

Even when the second and subsequent touch operations are accepted, the display control unit 41 displays the normal touch position on the display screen of the output unit 18 (step S19). In this case, as in FIG. 4, cross-shaped icons 101a, 101b, 101c, and 101d that prompt the user to perform a touch operation are displayed on the display screen of the output unit 18.
In the present embodiment, the first normal touch position display (step S13) and the second and subsequent normal touch position display (step S19) display the same icons 101a, 101b, 101c, and 101d. However, it is not limited to this. For example, the color, density, and shape of each icon 101a, 101b, 101c, 101d may be changed so as to be different from the display of the first normal touch position. Thereby, the user can identify whether the reception of the current touch operation is the reception of the first touch operation or the reception of the second or subsequent touch operations.

  On the other hand, when it is determined that the coordinates of the position where the first touch operation is performed and the coordinates of the position where the second touch operation are performed are not within an allowable range sufficient for use of calibration (step S24). : NO), a calibration failure warning is displayed (step S18). In this case, the display control unit 41 displays “Calibration failure” on the display screen of the output unit 18 to notify the user that the calibration has failed. In this case, as shown in FIG. 5, the control unit 47 determines that the touch operation is the second or subsequent touch (step S11: NO), and the failure touch position identification display as shown in FIG. 5 is performed (step S12). ).

FIG. 5 shows an example of a display screen on the display of the output unit 18 for identifying and displaying the failed touch position during the calibration process of FIG.
In FIG. 5, similarly to FIG. 4, cross-shaped icons (touch point instruction images) 201 a, 201 b, 201 c, and 201 d are arranged near the four corners of the display screen of the output unit 18.
If it is determined in step S24 that the amount of displacement is not within the predetermined range is the upper right corner of the display screen, the touch position of the icon 201b is highlighted around the icon 201b corresponding to the upper right corner of the display screen. The highlight icon 202 to be displayed is displayed. The user can identify whether or not the touch operation on the upper right of the display screen is inappropriate by checking the highlight icon 202. Therefore, the user can easily identify which part of the touch operation is a touch operation that is not suitable for calibration by checking the emphasis icon 202. In the above-described embodiment, the position where the calibration has failed is displayed to the user by displaying the emphasis icon 202 around the icon 201b corresponding to the location where the deviation amount is determined not to be within the allowable deviation amount range. However, it is not limited to this. For example, the icons 201a, 201b, 201c, and 201d are displayed in all the four corners of the display screen of the output unit 18 without clearly indicating a portion where the determined displacement amount is not within the displacement amount allowable range. May be.

  In the above-described embodiment, the emphasis icon 202 is displayed around the icon 201b corresponding to the location where it is determined that the deviation amount is not within the deviation amount allowable range, so that the position where the calibration has failed is displayed to the user. However, it is not limited to this. For example, as illustrated in FIG. 6, an icon 301 b corresponding to a location where it is determined that the determined shift amount is not within the shift amount allowable range may be indicated by an arrow 302.

FIG. 6 shows another embodiment of the display screen of the display of the output unit 18 for identifying and displaying the failed touch position during the calibration process of FIG. In FIG. 6, similarly to FIG. 5, cross-shaped icons (touch point instruction images) 301 a, 301 b, 301 c, and 301 d are arranged in the vicinity of the four corners of the display screen of the output unit 18.
An arrow 302 indicating the touch position of the icon 301b is displayed around the icon 301b corresponding to the location where it is determined in step S24 that the shift amount is not within the shift amount allowable range. Then, the text 303 displays “touch position where calibration has failed” to indicate that the location corresponding to the icon 301b is a location where calibration has failed. By checking the arrow 302 and the text 303, the user can identify whether the touch operation on the upper right of the display screen is inappropriate. Therefore, the user can easily identify which part of the touch operation is not suitable for calibration by checking the arrow 302 and the text 303.

  In the above-described embodiment, the icons 101a, urge the user to perform a touch operation on all four corners of the display screen of the output unit 18 as well as the portion where the deviation amount is determined not to be within the deviation amount allowable range. Although 101b, 101c, and 101d are displayed, it is not restricted to this. For example, as shown in FIG. 7, the icon 401 and the emphasis icon 402 may be displayed only at a location corresponding to a location where the determined shift amount is determined not to be within the shift amount allowable range.

FIG. 7 shows another embodiment of the display screen of the display of the output unit 18 for identifying and displaying the failed touch position during the calibration process of FIG. In FIG. 7, unlike FIG. 5, the cross-shaped icon (touch point instruction image) 402 is displayed on the display of the output unit 18 only at a location corresponding to a location where the discriminated discrepancy amount is not within the discrepancy amount allowable range. Is located near the upper right corner of the display screen.
An emphasis icon 402 indicating the touch position of the icon 401 is displayed around the icon 401 corresponding to the location where the displacement amount is determined not to be within the displacement amount allowable range in the process of step S24. The user can identify whether or not the touch operation on the upper right of the display screen is inappropriate by checking the highlighted icon. Therefore, the user can easily identify which part of the touch operation is a touch operation that is not suitable for calibration by checking the emphasis icon 402.

  In the above-described embodiment, in the above-described embodiment, not only the position where the shift amount is determined not to be within the allowable shift amount range but also all four corners of the display screen of the display of the output unit 18 Although icons 301a, 301b, 301c, and 301d for prompting a touch operation are displayed, the present invention is not limited to this. In addition, by displaying an arrow 302 indicating the touch position of the icon 301b around the icon 301b corresponding to the location where it is determined that the shift amount is not within the shift amount allowable range, the position where the calibration has failed is displayed to the user. However, it is not limited to this. For example, as shown in FIG. 8, only the icon 501 corresponding to a location where it is determined that the determined deviation amount is not within the deviation amount allowable range may be displayed, and the location may be indicated by an arrow 502.

FIG. 8 shows another embodiment of the display screen of the display of the output unit 18 for identifying and displaying the failed touch position during the calibration process of FIG. In FIG. 8, unlike FIG. 6, a cross-shaped icon (touch point instruction image) 501 is displayed on the display of the output unit 18 only at a location corresponding to a location where the discriminated deviation amount is not within the deviation amount allowable range. Is located near the upper right corner of the display screen.
An arrow 502 indicating the touch position of the icon 501 is displayed around the icon 501 corresponding to the location where it is determined in step S24 that the shift amount is not within the shift amount allowable range. Then, the text 503 displays “It is a touch position where calibration has failed” to indicate that the location corresponding to the icon 501 is a location where calibration has failed. By checking the arrow 502 and the text 503, the user can identify whether the touch operation on the upper right of the display screen is inappropriate. Therefore, by checking the arrow 502 and the text 503, the user can easily identify which part of the touch operation is not suitable for calibration.
The information processing apparatus 1 according to the first embodiment of the present invention has been described above.
Next, the information processing apparatus 1 according to the second embodiment of the present invention will be described.

[Second Embodiment]
The information processing apparatus 1 according to the second embodiment of the present invention can have basically the same hardware configuration and functional configuration as the information processing apparatus 1 according to the first embodiment.
Therefore, FIG. 1 is also a block diagram showing a hardware configuration of the information processing apparatus 1 according to the second embodiment. As in the first embodiment, the second embodiment can be configured by a digital camera, for example.

Further, the calibration process executed by the information processing apparatus 1 according to the second embodiment is basically the same as the calibration process according to the first embodiment. Therefore, FIG. 9 is also a flowchart for explaining the flow of calibration processing according to the second embodiment.
However, in the second embodiment, the process of steps S23 to S25 in the calibration process employs the flowchart of FIG. 9 instead of the flowchart of FIG. 3 employed in the first embodiment.
FIG. 9 is a flowchart for explaining the flow of calibration processing according to the second embodiment, which is executed by the information processing apparatus 1 of FIG. 1 having the functional configuration of FIG.

In the calibration process of FIG. 3 in the first embodiment described above, the unit touch operation is accepted twice, whereas in the calibration process of FIG. 9 in the second embodiment, the unit touch operation is accepted a plurality of times. The difference is that the calibration value is calculated based on the position coordinates more than the number of statistically reliable as the number of mothers. Specifically, the second embodiment is different from the first embodiment in that steps S43 to S47 are executed instead of steps S23 to S25.
Thus, hereinafter, such differences will be mainly described, and description of the coincident points will be omitted as appropriate.

  The calibration process is a process (may be executed in parallel) that is executed independently of a shooting process (not shown) performed by the user pressing the shutter button. It starts when the calibration button is pressed. In this case, the processing of step S31 to step S42 similar to the processing of step S11 to step S22 in the first embodiment is executed.

  In step S43, the deviation amount calculation unit 45 calculates the deviation amount based on the position coordinates acquired each time. Specifically, the deviation amount calculation unit 45 uses the coordinates of the position at which the first touch operation is performed among the coordinates of the position at which the touch operation has been acquired a plurality of times as a reference. Then, the deviation amount calculation unit 45 calculates the deviation amount between the coordinates of the position where the first touch operation is performed and the coordinates of the position where the touch operation is acquired each time. In the present embodiment, the coordinates of the position at which the first touch operation is performed are used as the reference coordinates, but the present invention is not limited to this, and any one of the touch operations is performed each time. The coordinates of the selected position can be used as a reference.

  In step S44, the deviation amount determination unit 46 determines whether or not the deviation amount calculated in step S43 has a deviation amount coordinate outside the predetermined range, that is, outside the deviation amount allowable range. Specifically, the shift amount determination unit 46 includes a shift amount between the coordinates of the position where the first touch operation is performed as a reference and the coordinates of the position where the touch operation is performed other than that, It is determined whether or not there is a coordinate having a deviation amount outside the allowable deviation amount range that is sufficient to use calibration. If it is determined that the calculated deviation amount is outside the predetermined range, that is, there is a coordinate outside the deviation amount allowable range, YES is determined in step S44, and the process proceeds to step S45. On the other hand, when it is determined that the calculated deviation amount is outside the predetermined range, that is, there is no coordinate outside the deviation amount allowable range, NO is determined in step S44, and the process proceeds to step S47. move on.

  In step S45, the deviation amount determination unit 46 excludes coordinates outside the deviation amount allowable range, that is, outside the deviation amount allowable range. Specifically, the deviation amount determination unit 46 identifies and excludes the position coordinates that have been determined that the deviation amount calculated in step S43 is greater than or equal to the deviation amount allowable range. It is determined whether the deviation amount is within the allowable range, for example, a deviation from 3σ or not greatly deviates from the acquired A / D value. In the present embodiment, a predetermined deviation amount allowable range is defined as a reliable range, but is not limited to this, and the size of the display screen of the display of the output unit 18 and position information acquisition The position can be appropriately changed based on the position information acquired by the unit 43.

  In step S <b> 46, the deviation amount determination unit 46 determines whether or not there are more coordinates than the statistically reliable number as the number of mother bodies. Specifically, the deviation amount determination unit 46 determines whether or not position coordinates sufficient for calibration still remain even if the coordinates outside the deviation amount allowable range are excluded in step S45. To do. If there are no more statistically reliable coordinates as the number of mother bodies, it is determined as NO in step S46, and the process returns to step S38. That is, until the number of coordinates that is statistically credible or more is acquired as the number of mothers, the determination process of step S31 to step S46: NO is repeatedly executed, and the calibration process is in a standby state. In other words, in the second embodiment, three or more calibration touch operations are accepted until the number of coordinates that is statistically reliable as the number of bases is acquired (step S40). Then, a deviation amount is calculated for each of the coordinates of the touch operation position of the calibration three times or more (step S43). If more than the number of statistically reliable coordinates is acquired as the number of mothers, it is determined as YES in step S46, and the process proceeds to step S47.

  In step S47, the calibration value calculation unit 48 calculates the average value of the coordinates remaining as a result of the exclusion in step S45 as the calibration value. Specifically, the calibration value calculation unit 48 calculates the average based on the coordinates of the position where the touch operation is acquired in step S35 and the coordinates of the position where the touch operation is acquired in step S41. The value is calculated as a calibration value.

  In step S48, the calibration value calculation unit 48 stores the calibration value calculated in step S47 in the correction information storage unit 52. The information processing apparatus 1 can perform calibration based on the calibration value stored in the correction information storage unit 52. When this process ends, the calibration process ends.

As described above, the information processing apparatus 1 according to the present embodiment includes the input operation receiving unit 42, the deviation amount calculation unit 45, the deviation amount determination unit 46, and the control unit 47.
The input operation receiving unit 42 receives an operation of touching or approaching an object on the touch panel as a calibration touch operation on the touch panel.
The deviation amount calculation unit 45 calculates the deviation amount of the coordinates of the calibration touch operation position with respect to the same location received by the input operation reception unit 42.
The deviation amount determination unit 46 determines whether or not the deviation amount calculated by the deviation amount calculation unit 45 is within a deviation amount allowable range.
The control unit 47 controls whether to perform calibration using the coordinates of the calibration touch position based on the determination result by the deviation amount determination unit 46.
In this case, if the deviation amount calculated by the deviation amount calculation unit 45 is out of the deviation amount allowable range, it is determined that the calibration operation has failed, and the calibration operation by the user is executed again. The calibration is prevented from being executed. Therefore, appropriate calibration can be executed even when the user performs a rough or incorrect operation.

  Furthermore, the control unit 47 of the information processing apparatus 1 according to the present embodiment performs a plurality of times for the same location by the input operation receiving unit 42 when the shift amount determination unit 46 determines that the shift amount is outside the shift amount allowable range. Control is performed to accept the calibration touch operation again. In this case, if the amount of deviation is outside the tolerance range of deviation, it is determined that the calibration operation has failed, the calibration operation by the user is performed again on the same location, and improper calibration is executed. I tried to prevent it. Therefore, appropriate calibration can be executed even when the user performs a rough or incorrect operation.

Furthermore, the input operation reception unit 42 of the information processing apparatus 1 according to the present embodiment receives a plurality of calibration touch operations for each of the plurality of locations on the touch panel, with each of the plurality of locations on the touch panel as the same location.
Then, the shift amount calculation unit 45 calculates the shift amount of each of the plurality of locations on the touch panel, and the shift amount determination unit 46 calculates the shift amount for each of the plurality of locations on the touch panel calculated by the shift amount calculation unit 45. It is determined whether each is within the allowable range.
Then, when the shift amount determination unit 46 determines that at least one of the shift amounts at the plurality of locations on the touch panel is outside the first range, the control unit 47 determines whether the input operation reception unit 42 has a plurality of the same locations on the touch panel. The control for receiving the calibration touch operation once is executed again. In this case, it is possible to reduce the burden on the user's calibration by allowing the user to perform the calibration operation again only at a location that is determined not to be within the allowable deviation amount range.

  Furthermore, the control unit 47 of the information processing apparatus 1 according to the present embodiment, when the shift amount determination unit 46 determines that at least one of the shift amounts at a plurality of locations is outside the shift amount allowable range, the input operation reception unit 42. The control for re-accepting a plurality of calibration touch operations for all of the plurality of locations is executed. In this case, expect calibration with higher accuracy by allowing the user to perform the calibration operation again at all locations, not just at the locations determined to be outside the tolerance range. Can do.

  Furthermore, the control unit 47 of the information processing apparatus 1 according to the present embodiment, when the shift amount determination unit 46 determines that at least one of the shift amounts at a plurality of locations is outside the shift amount allowable range, the input operation reception unit 42. Thus, the control for re-accepting the touch operation of the calibration for a plurality of times only for the part determined to be out of the allowable deviation amount range among the plurality of parts is executed. In this case, it is possible to reduce the burden on the user's calibration by allowing the user to perform the calibration operation again only at a location that is determined to be out of the allowable deviation amount range.

  Furthermore, the control unit 47 of the information processing apparatus 1 according to the present embodiment employs the average value of the coordinates of the touch operation position of a plurality of calibrations for the same location as a calibration result. In this case, a calibration with higher accuracy can be expected by adopting an average value of coordinates of a plurality of touch operation positions that have been successfully calibrated as a result of calibration.

  Furthermore, the information processing apparatus 1 according to the present embodiment includes an output unit 18. The output unit 18 displays the number of times the calibration touch operation received by the input operation receiving unit 42 is identifiable. In this case, the user's operability can be improved by displaying in a distinguishable manner whether the calibration operation to be executed subsequently is the first time or the second time.

  Furthermore, the information processing apparatus 1 according to the present embodiment further includes an output unit 18. When the deviation amount discriminating unit 46 determines that the deviation amount at the same location is out of the deviation amount allowable range, the output unit 18 displays the same location in an identifiable manner or displays a predetermined warning. In this case, when the control for executing the calibration operation by the user is performed again, it is possible to identify the touch position determined that the shift amount is not within the shift amount allowable range. Alternatively, by displaying a warning of a touch position that is determined not to be within the deviation amount allowable range, it is possible to clearly notify the user of the calibration touch position where the calibration has failed.

  Furthermore, the input operation accepting unit 42 of the information processing apparatus 1 according to the present embodiment accepts two calibration touch operations for the same part of the touch panel. Then, the deviation amount calculation unit 45 calculates the deviation amount for the other of the coordinates of the touch operation position of the calibration twice for the same location received by the input operation reception unit 42 with respect to the other as a predetermined reference. . In this case, since the shift amount is calculated based on the coordinates of the touch operation position of the calibration twice for the same location, it is expected that reliable calibration is executed.

Furthermore, the input operation receiving unit 42 of the information processing apparatus 1 according to the present embodiment receives three or more calibration touch operations on the same portion of the touch panel.
Further, the deviation amount calculation unit 45 calculates the deviation amount for each of the coordinates of the touch operation position of the calibration performed three or more times for the same location, which is received by the input operation reception unit 42.
Also, the deviation amount determination unit 46 determines whether or not each of the deviation amounts calculated by the deviation amount calculation unit 45 for the calibration touch operation for three or more times with respect to the same location is within the deviation amount allowable range. Determine.
Then, the control unit 47 excludes the coordinates of the touch operation position of the calibration that is determined to be the deviation amount outside the deviation amount allowable range by the deviation amount determination unit 46, and obtains the calibration execution result. In this case, the touch panel calibration operation performed by the user is performed three or more times, and the deviation amount of one or more touch positions is further calculated three times, and the calculated deviation amount is predetermined. It is further determined whether or not it is within the range. Further, since the determined deviation amount is further excluded by excluding the calibration operation in which it is determined that the deviation amount is not within the deviation amount allowable range, more accurate calibration can be expected.

  Further, the control unit 47 of the information processing apparatus 1 according to the present embodiment calculates the average value of the coordinates of the touch operation position of the calibration that is determined as the deviation amount within the deviation amount allowable range by the deviation amount determination unit 46. Adopted as a result of calibration. In this case, by adopting the average value of the coordinates of the touch operation position at the time of successful calibration as a result of the calibration, it is possible to expect a more accurate calibration.

Furthermore, the information processing apparatus 1 according to the present embodiment further includes a maximum value / minimum value determination unit 44.
The maximum value / minimum value determination unit 44 determines whether or not the coordinates of the touch operation position of the first calibration for the same location received by the input operation reception unit 42 are within a predetermined range.
When the maximum value / minimum value determination unit 44 determines that the coordinates of the touch operation position of the first calibration for the same location are out of the predetermined range, the control unit 47 determines that the same location by the input operation reception unit 42 The control for re-accepting the touch operation of the first calibration with respect to is executed.
In this case, it is determined whether or not the position coordinates of one or more coordinates of the touch position acquired by the first calibration operation are within a predetermined range. When it is determined that one or more position coordinates of the acquired touch position are not within the predetermined range, the first calibration operation is executed again. As a result, it is possible to discriminate in advance the first calibration operation that is obviously inappropriate as well as the second calibration operation.

  In addition, this invention is not limited to the above-mentioned embodiment, The deformation | transformation in the range which can achieve the objective of this invention, improvement, etc. are included in this invention.

In the above-described embodiment, when the input operation reception unit 42 receives a touch operation after the first time, that is, when it is determined NO in Step S11, the input operation reception unit 42 is out of the positions suitable for calibration. Although only a calibration touch operation is accepted for a location whose amount is outside the tolerance range, the present invention is not limited to this.
For example, it is possible to accept a plurality of calibration touch operations, not only where the deviation amount is out of the deviation amount allowable range among the positions suitable for calibration.
