  Hereinafter, a method for moving the image displayed on the image display control device 10 will be described. FIG. 4 is a diagram schematically illustrating an image moving operation method according to an embodiment of the present invention. Point A shown in FIG. 4 is the starting point of the drag operation, point C is the end point, and point B is a point on the path of the drag operation. A rectangular area 52 in FIG. 4 is an image displayed on the display unit 12. Note that FIG. 4 shows xy coordinate axes for the sake of explanation, and it is assumed that the user's seat is at the position of the origin of FIG.

  FIG. 5 is a flowchart illustrating an image moving operation method according to an embodiment of the present invention. First, when a point A at which no image is displayed on the display unit 12 is touched (see FIG. 4), this touch operation is detected by the touch sensor of the operation unit (touch panel) 16 (step S10). Then, based on the touch detection signal from the operation unit 16, counting is started by a timer (not shown), and the coordinates of the touch position are detected at predetermined time intervals following the drag operation. The coordinates of the touch position are recorded in the pointing table of the memory (SDRAM) 20 together with the moving distance, moving speed, and the like.

  FIG. 6 is a diagram illustrating an example of a pointing table. In the pointing table 40 shown in FIG. 6, the coordinates of the touch position detected at predetermined intervals, the movement distance from the immediately preceding detection point, and the movement speed are recorded. This moving distance is calculated from the coordinates of the detection point by the CPU 18, and the moving speed is calculated from the moving distance and the count number of the timer.

Returning to the description of the flowchart of FIG. 5 , the process proceeds to step S <b> 12, and the direction of the drag operation is detected by the drag direction determination algorithm.

  FIG. 7 is a flowchart showing the drag direction determination algorithm. First, when a drag operation is detected (step S10 in FIG. 4), the coordinates of the start point A and the second detection point B are read from the pointing table 40 (see FIG. 6) (step S30). Next, the slope k (= (Ya−Yb) / (Xa−Xb)) of the line segment AB is calculated from the coordinates of the points A and B (step S32). This gives the drag direction.

  In the present embodiment, the drag direction is calculated from the start point A and the second detection point B, but the drag direction may be calculated using the third and subsequent detection points.

  Here, a case where the drag direction is calculated using the third and subsequent detection points D will be described. FIG. 8 is a diagram illustrating a method of calculating the drag direction from the start point A and the point D. As shown in FIG. 8, when there is a detection point between the starting point A and the point D, the slope of the line segment AD (a chain line in the figure) may be the drag direction, or between the point A and the point D The slope of the straight line 42 obtained by least square approximation of the detection point group may be used as the drag direction.

Returning to the description of the flowchart of FIG. 5 again, the process proceeds to step S14, and the movement target image is selected by the selection image determination algorithm. At this time, for example, which image is selected is displayed to the user by a method such as changing the color of the frame of the selected image 52.

  FIG. 9 is a flowchart showing the selected image determination algorithm. First, an image displayed on a half line 50 (see FIG. 4) extending from the starting point A to the edge (END) of the display unit 12 with an inclination k on the opposite side of the user's seat is searched (step S40). Next, the display image 52 on the half line 50 is selected as a movement target image (step S42).

  FIG. 10 is a diagram for explaining a method of selecting a movement target image. As shown in FIG. 10A, an image 52 touching the half line 50 is a movement target image.

  In the present embodiment, as shown in FIG. 10B, when the center region 52A of the image 52 (for example, a rectangular region of about 50% of the area of the image) touches the half line 50, the moving target image It is good.

  In the present embodiment, all the images 52 on the half line 50 may be movement target images, or a part thereof (for example, an image separated from the user by a predetermined distance or more).

  In this embodiment, the image on the half line extending to the opposite side as viewed from the user's seat is moved. However, the image on the line passing through the start point and the end point of the drag operation is moved. Also good. In this case, an image displayed on the user side from the starting point of dragging can also be operated.

Returning to the description of the flowchart of FIG. 5 again, the process proceeds to step S16, and the movement distance L (A → C) between the points A and C is calculated. In step S16, the movement distance L (A → C) is calculated as the sum of the movement distances (La,..., Lb,..., Lc) of the pointing table 40.

  Then, the movement distance of the movement target image is calculated by a movement distance determination algorithm (described later) (step S18), and the display position of the movement target image is determined according to the movement distance calculated in step S18 and the drag direction detected in step S12. The display unit 12 is moved (step S20).

  As a result, as shown in FIG. 4, the image can be moved toward the user's seat without directly touching the image. Also, if a drag operation is performed in the direction from point B to point A, the image can be pushed in the opposite direction of the user.

  Next, an example of the movement distance determination algorithm will be described. FIG. 11 is a diagram illustrating correspondence between the finger movement of the drag operation and the movement of the image. As shown in FIG. 11, when the movement target image 52 moves from the point P to the point Q on the display unit 12 in accordance with the drag operation from the start point A to the end point C, the moving distance L (P → Q) of the image is It is represented by the following formula (1).

L (P → Q) = nL (A → C) (1)
Here, n is a proportionality coefficient, for example, n ≧ 1.

  According to the present embodiment, by setting the proportionality coefficient n to be greater than 1, the user can obtain a distant image by a small drag operation.

  Note that the proportional coefficient n may be changed according to the distance from the user (for example, the proportional coefficient n increases as the distance from the user's seat increases).

  In the above-described embodiment, the proportional coefficient n can be arbitrarily determined. For example, the proportional coefficient n may be changed according to the touch pressure, the moving speed of the drag operation, or the like.

  FIG. 12 is a diagram illustrating an example of correspondence between the touch pressure and the value of the proportional coefficient n, and FIG. 13 is a diagram illustrating an example of correspondence between the moving speed of the drag operation and the value of the proportional coefficient n. Note that the values of n shown in FIGS. 12 and 13 are merely examples, and these values are determined in consideration of operability in accordance with the size of the display unit 12 and the like.

  In the above moving distance determination algorithm, the image is stopped when the drag ends. However, after the hand is released from the display unit 12 and the drag operation is released, the image is stopped after the image moves a predetermined distance. You may make it do.

  FIG. 14 is a diagram illustrating correspondence between the finger movement of the drag operation and the movement of the image. As shown in FIG. 14, the movement target image 52 moves from the point P on the display unit 12 to the point Q ′ in accordance with the drag operation from the start point A to the end point C. When the user releases his hand at the end point C, the image 52 decelerates at a predetermined acceleration and stops at the point Q.

  If the moving speed at the point Q ′ is Vc, the acceleration is a, and the elapsed time from the end of the drag is t, the moving speed V of the image 52 is expressed by the following equation (2).

V = Vc-at (2)
In this case, the acceleration a may be variable. For example, if the value of the acceleration a is increased from the point R in the vicinity of the user's seat, the image can be stopped at a position that is easy to see in front of the user, so that the operability is improved. Further, with regard to the direction of the acceleration a, the operability can be further improved if the direction is closer to the user's seat.

  Next, another example of the image moving operation method will be described. FIG. 15 is a diagram schematically illustrating an image moving operation method according to another embodiment of the present invention. In FIG. 15, points A1 and A2 are starting points of the drag operation, points C1 and C2 are end points, and points B1 and B2 are points on the path of the finger of the drag operation. A rectangular area 52 in FIG. 15 is an image displayed on the display unit 12.

  FIG. 16 is a flowchart showing an image moving operation method according to another embodiment of the present invention. FIGS. 17 to 19 are diagrams showing modes of the drag operation.

  First, as shown in FIG. 15, when two points A1 and A2 on the display unit 12 are touched almost simultaneously, a touch operation is detected by the touch sensor of the operation unit (touch panel) 16 (step S50). Then, as in the above-described embodiment, counting is started by a timer (not shown) based on the touch detection signal from the operation unit 16, and the coordinates of the touch position are calculated at predetermined time intervals. The coordinates of the touch position are recorded in the pointing table of the memory (SDRAM) 20 together with the moving distance, moving speed, and the like.

  Next, the drag directions (inclinations k1, k2) of the drag operation starting from the two points A1 and A2 are detected by the drag direction determination algorithm (step S52). Note that the drag direction determination algorithm is the same as that in the above-described embodiment, and thus description thereof is omitted.

  Then, the movement target image is selected by the selected image determination algorithm (step S54). As shown in FIG. 15, when dragged in a direction substantially perpendicular to the line segment A1A2, half straight lines 50-1 and 50 that extend from the starting points A1 and A2 to the opposite side of the user's seat at inclinations k1 and k2, respectively. The image 52 displayed in the region between -2 (selection region) is selected as the movement target image.

  As shown in FIG. 17, when the two drag paths are substantially parallel (y direction) and the positions of the starting points A1 and A2 are shifted in the y direction, the line segment A1A2 is substantially perpendicular to the drag path. The line segment thus rotated becomes the width of the selected area.

  As shown in FIG. 18, when three or more points are touched simultaneously on the display unit 12, the width of the selected area is set so that the width of the selected area becomes maximum. In FIG. 18, the line segment A1A5 is the width of the selected region.

  In the present embodiment, the image between the two half lines extending in the opposite direction when viewed from the user's seat is moved, but between the two straight lines passing through the starting point and the ending point of the drag operation. The image may be moved.

  Next, the movement distances L (A1 → C1) and L (A2 → C2) of each drag operation are calculated (step S56), and the movement distance of the movement target image is calculated by the movement distance determination algorithm (step S58). . Here, the moving distance of the image is calculated in the same manner as in the above-described embodiment, using one of the moving distances L (A1 → C1) and L (A2 → C2) of each drag operation, or the average.

  Further, the movement direction of the movement target image is calculated from the combined vector direction of the direction vectors of the half lines 50-1 and 50-2. The moving direction may be either one of the direction vectors of the half lines 50-1 or 50-2.

  As shown in FIG. 19, when the two drag paths are substantially fan-shaped, the moving direction of the image is the intersection E of the extension lines to the user side of the half lines 50-1 and 50-2 (fan-shaped It is good also as moving toward the important position.

  Then, the display position of the movement target image is moved on the display unit 12 according to the movement distance calculated in step S58 and the above movement distance (step S60).

  When the operation of this embodiment is performed using an input pen, the same operation may be performed using two input pens, or a selection area can be set with one input pen. Also good. Here, when the selection area is set with one input pen, for example, the start point A1 is first selected by an operation such as double-clicking, and the second start point A2 is dragged. Processing can be performed.
