When the x-axis coordinates (X1A) (X1B) intersect, the enlargement / reduction set magnification before the intersection and the enlargement / reduction set magnification after the intersection are switched.

  FIG. 7 shows an enlargement / reduction display process of the second embodiment using the two display devices (A) 11A, (B) 11B and the touch panels (A) 12A, (B) 12B in the foldable portable information terminal 10. It is a flowchart which shows.

  As shown in FIG. 6, on each of the touch panels (A) 12A and (B) 12B in the upper and lower display devices (A) 11A and (B) 11B, for example, touch with each fingertip of the user's right hand and left hand When an operation is detected (step A1), the coordinates (X0A, Y0A) (X0B, Y0B) specified on the respective display screens (11A, 11B) are displayed on the touch panels (A) 12A, (B). It is calculated based on the touch position detection signal from 12B (step A2).

  Here, the fingertips at the first designated points (X0A, Y0A) (X0B, Y0B) on the two display screens (11A, 11B) are moved along the x-axis direction by, for example, arrows a and b in FIG. As shown, when the movement of the touch designated point is detected when the display image (25) is first moved in the shrinking direction (step A3), the designated point coordinates (X1A) of the destination (moving) are detected. , Y1A) (X1B, Y1B) is calculated (step A4), and it is determined whether or not each x-axis coordinate (X1A) (X1B) intersects (step A5).

  Then, if it is determined that the x-axis coordinates (X1A) (X1B) of the designated point that is moving on each display screen (11A, 11B) do not intersect (step A5 (N)), that is, each designation at the present time If it is determined that the point coordinates (X1A, Y1A) (X1B, Y1B) are located in front of the intersection position K and are moving in the direction of shrinking the display image (25) from the beginning, Each specified point coordinate (X1A, Y1A) (X1B) at the time of the current coordinate calculation (after movement) from the X direction difference (X0A-X0B) between the specified point coordinates (X0A, Y0A) (X0B, Y0B) at the time of coordinate calculation , Y1B) is determined to have a smaller X-direction difference (X1A-X1B) (step A6 (N)).

  Then, the image data (25) being displayed is reduced according to the movement of each designated point (X1A, Y1A) (X1B, Y1B) according to the set magnification (small) 22g set by default at the start of the display process. Is displayed (step A7).

  After that, when the designated point coordinates (X1A, Y1A) (X1B, Y1B) reach the intersection position K, it is determined that the x-axis coordinates (X1A) (X1B) of the designated points intersect. (Step A5 (Y)), it is determined whether or not the current change magnification flag 22f is set to "0" (Step A9).

  Here, when it is determined that the current change magnification flag 22f is set to “0” by default at the start of the display process (step A9 (Y)), the change magnification flag 22f is set to “0”. “→” is changed and set (step A10), and the current set magnification (small) 22g is changed to the set magnification (large) 22g (step A11).

  Then, the movement of each designated point (X1A, Y1A) (X1B, Y1B) that has reached the intersection position K is further continued as indicated by arrows a and b, so that the display image (25) is expanded. When the current coordinate is calculated from the X direction difference (X1A-1-X1B-1) between the specified point coordinates (X1A-1, Y1A-1) (X1B-1, Y1B-1) at the previous coordinate calculation If it is determined that the X-direction difference (X1A-X1B) between the specified point coordinates (X1A, Y1A) (X1B, Y1B) (after movement) is larger (steps A3 to A6 (Y)), the change is made. The displayed image data (25) is enlarged and displayed in accordance with the movement of the designated points (X1A, Y1A) (X1B, Y1B) in accordance with the set magnification (large) 22g (step A8).

  Thereafter, for example, with each fingertip placed on the display screen (11A, 11B), the moving operation of each designated point (X1A, Y1A) (X1B, Y1B) is reversed in the direction of shrinking the display image (25). If this is the case, the X direction difference (X1A-1-X1B-1) between the specified point coordinates (X1A-1, Y1A-1) (X1B-1, Y1B-1) at the time of the previous coordinate calculation will be Since it is determined that the X-direction difference (X1A-X1B) between the designated point coordinates (X1A, Y1A) (X1B, Y1B) at the time of coordinate calculation (after movement) is smaller (steps A3 to A6 (N)). The displayed image data (25) is reduced and displayed in accordance with the movement of the designated points (X1A, Y1A) (X1B, Y1B) in accordance with the set magnification (large) 22g that has been changed (step A7). .

  When it is determined that the designated point coordinates (X1A, Y1A) (X1B, Y1B) have reached the intersection position K, and the x-axis coordinates (X1A) (X1B) of the designated points have intersected. (Step A5 (Y)), since it is determined that the current change magnification flag 22f is changed and set to "1" (Step A9 (N)), the change magnification flag 22f is changed from "1" to "" It is reset to 0 ″ (step A13), and the changed current set magnification (large) 22g is changed again to the set magnification (small) 22g (step A14).

  Further, the movement of each designated point (X1A, Y1A) (X1B, Y1B) that has reached the intersection position K is continued in the direction opposite to the arrows a and b, thereby expanding the display image (25). The current coordinate is more than the X-direction difference (X1A-1−X1B-1) between each specified point coordinate (X1A-1, Y1A-1) (X1B-1, Y1B-1) at the previous coordinate calculation. When it is determined that the X-direction difference (X1A−X1B) between the designated point coordinates (X1A, Y1A) (X1B, Y1B) at the time of calculation (after movement) is larger (steps A3 to A6 (Y)), The image data (25) being displayed is enlarged and displayed in accordance with the movement of each designated point (X1A, Y1A) (X1B, Y1B) in accordance with the set magnification (small) 22g which has been changed again and set (step) A8).

  Thereafter, when the user touch operation on the display screen (11A, 11B) is canceled and it is determined that the fingertip has been removed from the touch panel (A) 12A, (B) 12B (step A12), the series of enlargement / reduction display processes described above. Is terminated (step A12 → end).

  Therefore, the enlargement / reduction display function of the second embodiment using the two display devices (A) 11A, (B) 11B and the touch panels (A) 12A, (B) 12B in the foldable portable information terminal 10 having the above-described configuration. When the movement of each touch designated point (X0A, Y0A) (X0B, Y0B) on each display screen (A) 11A, (B) 11B is detected, between the designated point coordinates of the movement source The difference between the x-axis direction difference and the x-axis direction difference between the designated point coordinates of the movement destination is compared, and the x-direction difference between the designated points of the movement destination is larger than the x-direction difference between the designated points of the movement source. If it is determined that the display image data (25) is smaller, the display image data (25) is reduced according to the movement of each designated point according to the set magnification (small or large) 22g set according to the set magnification flag 22f. If it is judged, it is enlarged. Therefore, unlike the enlargement / reduction operation in the conventional display device, any two points on the upper display screen (11A) and the lower display screen (11B) are directly designated and the display image is enlarged or reduced. Enlargement or reduction display can be performed by a simple operation that is easy to understand in a sense of moving in a direction.

  In addition, when the x-axis coordinates (X1A) (X1B) associated with the movement of each designated point intersect, the setting magnification flag 22f is set in accordance with the change from “0” to “1”. When the magnification 22g is changed from “small” to “large” and enlarged or reduced, and when crossing again, the setting magnification flag 22f is changed again from “1” to “0”. Since the set magnification 22g is changed again from “large” to “small” and enlarged or reduced, the current enlargement / reduction set magnification is changed from “small” to “large” or “large” to When the display image (25) is to be enlarged / reduced instead of “small”, this can be done simply by crossing each designated point in the X-axis direction.

  In the enlargement / reduction display function of the second embodiment, designated points on the respective display screens (11A, 11B) are targeted for two display screens (11A, 11B) that are vertically expanded and adjacent to each other. The display image data (25) is enlarged / reduced by moving in the x-axis direction in the direction of expanding each other or in the direction of shrinking. However, the enlargement / reduction of the third embodiment will be described. As described in the display function, the display image data (25) is obtained by moving the designated points on each display screen (11A, 11B) in the y-axis direction so as to expand or contract each other. For example, a designated point that is moving in the shrinking direction enters the boundary between the display screens (11A, 11B), or further exceeds one of the display screens (11A, 11B). 11A or If the two specified points are or accidentally get onto 11B), it may not generate the malfunction configuration performed appropriately corresponding control.

(Third embodiment)
FIG. 8 shows an enlargement / reduction display function of the third embodiment using the two display devices (A) 11A and (B) 11B and the touch panels (A) 12A and (B) 12B in the foldable portable information terminal 10. It is a figure which shows the user operation form in.

  In the enlargement / reduction display function of the third embodiment, for example, the fingertips of both hands placed on each display screen (11A, 11B) a display image displaying two display screens (11A, 11B) as one screen. Is enlarged and displayed by moving in the direction away from each other along the y-axis coordinates, and reduced and displayed by moving in the approaching direction.

  When the fingertips are moved along the y-axis direction on the upper and lower display screens (11A, 11B), for example, as shown in FIG. 8A, designated points that are moving in a contracting (approaching) direction are displayed. When the boundary between the display screens (11A and 11B) is entered, the movement locus of each designated point is shown in FIG. It is determined that they intersect across the boundary of the display screen, and the display returns to the same enlarged / reduced display again. In addition, two designated points are entered on the other display screen (11B or 11A) when the designated point on one display screen (11A or 11B) exceeds the boundary between the display screens (11A, 11B). In the case where it has occurred, the display returns to the same enlarged / reduced display again after waiting for the return of each designated point on each display screen (11A, 11B) within a predetermined time.

  FIG. 9 shows an enlargement / reduction display process of the third embodiment using the two display devices (A) 11A, (B) 11B and the touch panels (A) 12A, (B) 12B in the foldable portable information terminal 10. It is a flowchart which shows.

  As shown in FIG. 8A, in each of the touch panels (A) 12A and (B) 12B in the upper and lower display devices (A) 11A and (B) 11B, for example, each of the user's right hand and left hand When the touch operation by the fingertip is detected (step B1), the coordinates (X0A, Y0A) (X0B, Y0B) designated on the display screens (11A, 11B) are displayed on the touch panels (A) 12A, (B) Calculated based on the touch position detection signal from 12B (step B2).

  Here, the fingertip at the first designated points (X0A, Y0A) (X0B, Y0B) on the two display screens (11A, 11B) is moved along the y-axis direction, for example, arrow a in FIG. , B, when the movement of the touch designated point is detected when the display image (25) is first moved in the shrinking direction (step B3), the designated point of the destination (moving). The coordinates (X1A, Y1A) (X1B, Y1B) are calculated (step B4).

  Then, the specified point coordinates (X1A, Y1A) at the time of the current coordinate calculation (after movement) than the y-direction difference (Y0A-Y0B) between the specified point coordinates (X0A, Y0A) (X0B, Y0B) at the previous coordinate calculation. ) When it is determined that the Y-direction difference (Y1A-Y1B) between (X1B, Y1B) is smaller, the image data (25) being displayed according to the preset enlargement / reduction ratio is designated by each As the points (X1A, Y1A) (X1B, Y1B) move, they are reduced and displayed (step B5).

  On the other hand, when the fingertip at each designated point (X0A, Y0A) (X0B, Y0B) is moved in the direction to expand along the y-axis direction, each designated point coordinate (X0A , Y0A) (X0B, Y0B) Y-direction difference (Y1A) between the designated point coordinates (X1A, Y1A) (X1B, Y1B) at the time of the current coordinate calculation (after movement) than the y-direction difference (Y0A-Y0B). When it is determined that -Y1B) is larger, the displayed image data (25) is moved according to a preset enlargement / reduction ratio to the designated points (X1A, Y1A) (X1B, Y1B). Accordingly, the image is enlarged and displayed (steps B3 to B5).

  For example, as shown in FIG. 8A, the fingertips at the designated points (X0A, Y0A) (X0B, Y0B) are reduced and displayed while being moved in the direction of contraction along the y-axis direction. In this state (steps B3 to B6 → B3), one finger, in this case, the finger that has been moved on the upper display screen (11A) side enters the boundary with the lower display screen (11B), and the one finger When it is determined that the touch detection of the designated point (X1A, Y1A) due to has disappeared (step B6 (Y)), the timer operation of the timer counter 22j is started for a predetermined time (step B7).

  Then, before the elapse of a fixed time (timer over) due to the timer operation is determined (step B8 (N)), the other finger, that is, the finger moved on the lower display screen (11B) side in this case is also the same. When it is determined that touch detection of the designated points (X1A, Y1A) (X1B, Y1B) by both fingers has been eliminated (step B9 (Y)), entering the boundary portion between the display screens (11A, 11B) If it is determined that the touch detection on both display screens (11A, 11B) has been restored before the elapse of the fixed time (timer over) is determined (step B11 (N)) (step B12 (Y)). ), For example, as indicated by arrows c and d in FIG. 8B, it is determined that the movement trajectory of each designated point has moved across the boundary portion of the display screen (11A, 11B). The new designated point coordinates (X1A, Y1A) (X1B, Y1B) at the time of the H detection recovery are calculated (step B13).

  Then, it is determined whether normal touch detection has been performed by confirming whether or not each newly calculated designated point coordinate (X1A, Y1A) (X1B, Y1B) is an actual coordinate position (step B14 ( Y)), and after that, the movement of the designated point coordinates (X1A, Y1A) (X1B, Y1B) is judged again, and the designated point coordinates (X1A, Y1A) (X1B, Y1B) are similarly determined. The display image data (25) is enlarged / reduced in accordance with the movement of (step B3 to B5).

  In Steps B6 and B7, for example, it is determined that the touch detection of the designated point (X1A, Y1A) by one finger has been lost, for example, and after a certain period of time timer operation has started, a certain period of time has elapsed (timer over). (Step B8 (Y)), or whether it is determined that the designated point coordinates for detecting the touch position have moved abruptly, and it is determined that a certain time has elapsed from the timer operation (timer over) (Step B9-> B10-> B11 (Y)) or touch detection of the designated point with the other finger is also eliminated, and the timer operation is started without touch detection of both designated points (X1A, Y1A) (X1B, Y1B). When it is determined that the predetermined time has elapsed (timer over) (step B9 → B11 (Y)), one of the display screens (11A, 11B) It is determined that both fingers are placed on the top or that the user operation for the enlargement / reduction has been completed, and the series of enlargement / reduction display processing is terminated (step B8 (B11)). → end).

  Therefore, the enlargement / reduction display function of the third embodiment using the two display devices (A) 11A, (B) 11B and the touch panels (A) 12A, (B) 12B in the foldable portable information terminal 10 having the above configuration. According to the above, when the movement in the y-axis direction of each touch designated point (X0A, Y0A) (X0B, Y0B) on each display screen (A) 11A, (B) 11B is detected, The display image data (25) is enlarged / reduced according to the difference between before and after the movement and a predetermined set magnification depending on whether the specified point coordinates are in the expanding direction or the contracting direction. It is completely different from the above operation, and it is sensuously understood that any two points on the upper display screen (11A) and the lower display screen (11B) are directly designated and the display image is moved in the direction of expanding or contracting. Enlargement or reduction display can be performed by a simple operation that is easy to understand.

  Then, during the enlargement / reduction display processing of the display image accompanying the movement operation of the designated points (X0A, Y0A) (X0B, Y0B) along the y-axis direction, the designated points (X0A, Y0A) (X0B, Y0B) Even when it is determined that the touch detection of one or both designated points is temporarily lost when the finger that moves the screen passes through the boundary portion between the display screens (11A, 11B), the fixed time elapses due to the timer operation. If it is determined that the touch detection of both the designated points has been performed again before, the enlargement / reduction process of the display image corresponding to the movement of the new designated point coordinates is resumed. / Discontinuation of processing associated with passing of designated points between the display screens (11A, 11B) during the reduced display processing can be minimized.

  In the enlargement / reduction display function of each of the embodiments, the touch panel (A) 12A, (A) 11B detects by placing a finger on each display screen ((A) 11A, (B) 11B). A configuration for enlarging or reducing the display image according to whether the calculated designated point coordinates (X0A, Y0A) (X0B, Y0B) are moved in the direction of expanding or reducing the distance between the specified points. However, as will be described in the enlargement / reduction display function of the fourth embodiment, the display image in which the two display screens ((A) 11A, (B) 11B) are displayed as one display screen. After specifying the enlargement / reduction center position by touching one point on any one display screen (image), the touch point is moved in a predetermined direction on the other display screen. Perform the move operation Accordingly, the display may be enlarged or reduced with the image position designated on the one display screen as the center.

(Xb, Yb) is calculated, and the movement determination standby state for the designated point coordinates (Xb, Yb) is entered (steps C4 / C6).

  Here, as shown in FIG. 10A, the designated point coordinates (Xb, Yb) with respect to the other display screen (11B) have moved in the upward (−y axis direction) or right (+ x axis direction) direction. Is determined (step C4 (Y)), the enlargement amount is calculated according to the moving distance and a predetermined set magnification, and the touch designated point (Xa, Ya) on the one display screen (11A) is the center. The displayed image is enlarged and displayed (step C5).

  On the other hand, if it is determined that the designated point coordinates (Xb, Yb) with respect to the other display screen (11B) have moved downward (+ y axis direction) or left (−x axis direction) (step C6 ( Y)), the amount of reduction is calculated according to the moving distance and a predetermined set magnification, and the displayed image is reduced around the touch designated point (Xa, Ya) on the one display screen (11A). Is displayed (step C7).

  In FIG. 10B, after the touch designated point (Xa, Ya) is first detected on the lower display screen (11B) as one display screen (step C1 → C2), the other upper display screen ( 11A) When the movement of the designated point coordinates (Xb, Yb) in the lower left direction is determined (step C3 → C6 (Y)), the reduced display centered on the first touch designated point (Xa, Ya). The operation (step C7) is shown.
