  Embodiments of the present invention will be described below by taking the first to fourth embodiments as examples.

1. First Embodiment [Configuration of Image Display System]
First, the first embodiment will be described. FIG. 1 is a schematic configuration diagram of an image display system 9 according to the present embodiment. As shown in the figure, the image display system 9 includes a remote control device 1, an STB 2, and a display device 3. A rectangular touch panel 11 is provided on the surface of the remote control device 1, and a rectangular display 31 is provided on the surface of the display device 3.

  In the following description, it is assumed that the x, y, and z directions that define a three-dimensional region and the X and Y directions that define a two-dimensional region are directions as shown in FIG. That is, the x direction (the direction of the x coordinate axis) is the direction in which the long side of the touch panel 11 extends, and the y direction (the direction of the y coordinate axis) is the direction in which the short side of the touch panel 11 extends, and the z direction (the direction of the z coordinate axis). Is a direction perpendicular to the surface of the touch panel 11. Note that three-dimensional coordinates (x, y, z), which will be described later, are coordinates on a three-dimensional orthogonal coordinate system including x, y, and z coordinate axes.

  The X direction (the direction of the X coordinate axis) is a direction in which the long side of an image (image P described later) displayed on the display 31 extends, and the Y direction (the direction of the Y coordinate axis) is a direction in which the short side of the image extends. is there. Note that two-dimensional coordinates (X, Y) described later are coordinates on a two-dimensional orthogonal coordinate system including X and Y coordinate axes.

  Each configuration of the remote control device 1, the STB 2, and the display device 3 will be described below with reference to the block diagram shown in FIG. The remote control device 1 includes a control unit 12 and a remote control signal transmission unit 13 in addition to the touch panel 11.

  The touch panel 11 is a three-dimensional touch panel that continuously receives an operation input of three-dimensional coordinates (x, y, z) by a user, and sends information on the three-dimensional coordinates to the control unit 12. The touch panel 11 recognizes the coordinates of the position of the user's fingertip or the like in the neighboring three-dimensional space as the position of the three-dimensional coordinates. The means for accepting the operation input of the three-dimensional coordinates is not limited to the touch panel, and other means may be adopted.

  Based on the information received from the touch panel 11, the control unit 12 controls the remote control signal transmission unit 13 to transmit a remote control signal representing the three-dimensional coordinates (x, y, z). The remote control signal transmission unit 13 is configured to wirelessly transmit a remote control signal in accordance with control by the control unit 12.

  The STB 2 includes an image acquisition unit 21, an image processing unit 22, an image signal generation unit 23, a remote control signal reception unit 24, a control unit 25, a correspondence setting unit 26, a cursor position specifying unit 27, and the like.

  The image acquisition unit 21 receives various images P (for example, TV program images, web pages, etc.) from outside or other parts of the STB 2 (not shown) (for example, a TV tuner, a network communication unit, an application in the STB 2, an internal memory of the STB 2) Site image, photograph, etc.) are acquired, and the image P is sent to the image processing unit 22. The image acquisition unit 21 has, for example, a TV broadcast reception function and an Internet connection function, and can acquire images P such as TV programs and websites. The image P may include an object for which a touch operation is effective.

  The image processing unit 22 performs predetermined processing on the image P acquired by the image acquisition unit, and sends the processed image P to the image signal generation unit 23. The process performed by the image processing unit 22 includes a process of superimposing a cursor CS (described later in detail) on the image P.

  The image signal generation unit 23 generates an image signal representing the image P processed by the image processing unit 22, and outputs this image signal to the display device 3. The display device 3 displays the image P on the display 31 based on the image signal input from the image signal generator 23.

  The remote control signal receiving unit 24 receives the remote control signal transmitted from the remote control device 1 (remote control signal transmitting unit 13), and sends various information included in the remote control signal to the control unit 25. As a result, the control unit 25 can obtain information on three-dimensional coordinates (x, y, z) and the like.

  The control unit 25 controls the operation of each unit in the STB 2 so that the STB 2 operates normally. The operation performed by the control unit 25 includes an operation of sending information on the three-dimensional coordinates (x, y, z) to the correspondence setting unit 26 and the cursor position specifying unit 27.

  The correspondence setting unit 26 sets the correspondence between the two-dimensional coordinates (x, y) and the two-dimensional coordinates (X, Y). Two-dimensional coordinates (X, Y) are coordinates indicating a position on the image P. The position of the two-dimensional coordinates (x, y) is mapped on the image P by setting the corresponding relationship. Note that the x and y coordinates in the two-dimensional coordinates (x, y) are the same as the x and y coordinates in the three-dimensional coordinates (x, y, z).

  In addition, the cursor position specifying unit 27 specifies the position of the cursor CS to be superimposed on the image P based on the correspondence (setting of correspondence) set by the correspondence setting unit 26. That is, the cursor position specifying unit 27 specifies the coordinates (X, Y) corresponding to the current two-dimensional coordinates (x, y) as the current cursor CS position. As described above, the cursor position specifying unit 27 has a function of converting the two-dimensional coordinates (x, y) into the two-dimensional coordinates (X, Y) on the image P.

  The cursor position specifying unit 27 sends information on the specified coordinates (X, Y) to the image processing unit 22. Then, the image processing unit 22 performs processing on the image P so that the cursor is superimposed on the position of the coordinates (X, Y). As a result, the user can move the cursor CS to a desired position on the image P by operating the cursor CS using the touch panel 11 while viewing the image P displayed on the display 31.

  Note that the control unit 25 determines whether or not a fingertip or the like is touching the touch panel 11 based on the z coordinate in the three-dimensional coordinates (x, y, z), and recognizes various touch operations. That is, the control unit 25 recognizes various touch operations such as a short press, a long press, and a drag based on a contact time of the fingertip or the like with the touch panel 11 or a moving state of the fingertip or the like that is in contact.

  When an object for which a touch operation is valid is included in the image P, when the touch operation is performed on the object, the control unit 25 considers that the user has given an instruction according to the object and the content of the operation. As an example, when a short press touch operation is performed on an object of a certain option, the control unit 25 considers that the option has been selected by the user.

[Setting of correspondence, etc.]
As described above, the correspondence setting unit 26 sets the correspondence between the two-dimensional coordinates (x, y) and the two-dimensional coordinates (X, Y). Further, the correspondence setting unit 26 changes the setting of the correspondence according to the z coordinate (hereinafter simply referred to as “z coordinate”) in the three-dimensional coordinates (x, y, z). .

  In the case of the present embodiment, the setting of the corresponding relationship is changed according to the magnitude relationship between the z coordinate and the predetermined threshold value α. The threshold value α is a fixed threshold value appropriately determined in advance based on a predetermined test result or the like in the STB2 development stage.

  Hereinafter, the change of the setting of the correspondence will be described in more detail with reference to FIGS. 3 to 5. 3 and 4 schematically show the correspondence between the input enabled area CT1 and the cursor movable area CT2. The input possible area CT1 is an entire area in the xy plane direction on the touch panel 11 (an area where a user can input an operation), and corresponds to a fluctuation range of coordinates (x, y). The cursor movable area CT2 is an area in which the cursor CS on the image P can be moved, and corresponds to a fluctuation range of coordinates (X, Y).

  FIG. 3 shows a correspondence relationship between the input enabled area CT1 and the cursor movable area CT2 when the z coordinate is larger than the threshold value α (a finger or the like is further from the touch panel 11 than the threshold value α). The cursor movable region CT2 shown in the figure is set so as to substantially match the entire region of the image P displayed on the display 31.

  On the other hand, FIG. 4 shows a correspondence relationship between the input possible region CT1 and the cursor movable region CT2 when the z coordinate is smaller than the threshold value α (a finger or the like is closer to the touch panel 11 than the threshold value α). The cursor movable region CT2 shown in this figure is set to be a partial region (region having a smaller area than the entire region) of the image P displayed on the display 31.

FIG. 5 schematically shows the correspondence between the coordinates (x, y) in the input-capable region CT1 and the coordinates (X, Y) in the cursor-movable region CT2. As shown in this figure, the input enabled region CT1 has an upper left corner coordinate (0, 0) and a lower right corner coordinate (x _max , y _max ), and 0 ≦ x ≦ x _max and 0 The region satisfies the condition of ≦ y ≦ y _max . The cursor movable region CT2 is set such that 0 ≦ X ≦ X _max and 0 ≦ Y ≦ Y _{max where} the coordinates of the upper left corner are (0, 0) and the coordinates of the lower right corner are (X _max , Y _max ). An area that satisfies the above condition.

The coordinates (X, Y) are determined according to the following expression (1) when the coordinates (x, y) are specified.
X = (X _max / x _max ) × x
Y = (Y _max / y _max ) × y (1)
As is clear from the above equation (1), the outer edge of the input possible area CT1 corresponds to the outer edge of the cursor movable area CT2. X is proportional to x, and Y is proportional to y. Therefore, the user can easily operate the cursor as desired by regarding the input possible area CT1 as the cursor movable area CT2.

  As described above, in the present embodiment, the correspondence relationship between the coordinates (x, y) and the coordinates (X, Y) is changed so that the area of the cursor movable region CT2 changes according to the z coordinate. For this reason, the user uses the remote control device 1 to perform a fine operation (for example, an operation of touching a character on the software keyboard for character input) to pinpoint a small area on the image P. Is easy.

  That is, when performing such a fine operation, the user can bring the finger or the like closer to the touch panel 11 so that the z coordinate becomes smaller than the threshold value α, and the area of the cursor movable region CT2 can be reduced. . The smaller the area of the cursor movable region CT2, the smaller the amount of movement of the cursor CS when a finger or the like is slid in the xy plane direction. As a result, it becomes easy to perform fine operations.

  The image processing unit 22 may superimpose the cursor CS on the image P, and may superimpose a graphic such as a frame line representing the outer edge of the cursor movable region CT2 on the image P. In this way, the user can grasp the outer edge of the current cursor-movable region CT2, so that the cursor CS can be more easily operated.

  Further, the switching of the area of the cursor movable region CT2 may be executed immediately when the magnitude relationship between the z coordinate and the threshold value α changes. The switching may be performed when the magnitude relationship between the z coordinate and the threshold value α is changed and the state is maintained for a certain time. In this way, it is possible to avoid a situation where the switching is excessively performed due to a slight change in the z coordinate near the threshold value α.

  Further, on / off of a function for switching the area of the cursor movable region CT2 according to the z coordinate (hereinafter referred to as “switching function” for convenience) can be switched according to a predetermined condition. good. As an example, on / off of the switching function may be switched according to a user setting. In this case, a user who thinks that the switching function is unnecessary can set the switching function to OFF.

  As another example, on / off of the switching function may be automatically switched according to information on an object for which a touch operation included in the image P is valid. That is, on / off of the switching function may be switched based on information such as the size, number, or arrangement density of the object.

  For example, if the object is relatively large, the user can easily touch the object even if the area of the cursor movable region CT2 is not reduced. Therefore, in this case, the switching function is turned off. On the other hand, if the object is relatively small, it is difficult for the user to appropriately touch the object unless the area of the cursor movable region CT2 is reduced. Therefore, in this case, the switching function is turned on.

  As yet another example, the STB 2 may be configured to record the history of past touch operations, and on / off of the switching function may be automatically switched based on the history. For example, when the distribution of coordinates (X, Y) touched in the past is not scattered throughout the image P and is biased to a specific area of the image P, the touch operation in that area is easier. In other cases, the switching function may be turned on, and in other cases, the switching function may be turned off.

  When the STB 2 is configured to record the past touch operation history, the area or position (or both) of the cursor movable region CT2 may be determined based on the history. good. For example, when the distribution of coordinates (X, Y) touched in the past is not scattered throughout the image P and is biased to a specific region of the image P, the region is covered as much as possible. The area or position may be determined.

  Further, as already described, the threshold value α is provided in the STB 2 of the present embodiment, and the coordinates (x, y) are set so that the area of the cursor movable region CT2 changes according to the magnitude relationship between the z coordinate and the threshold value α. ) And the coordinates (X, Y). Here, the threshold value α is not limited to one, and a plurality of threshold values α may be provided.

  When a plurality of threshold values α are provided, the area of the cursor movable region CT2 may be changed each time the magnitude relationship between the z coordinate and any one of the threshold values α is changed. For example, when the z coordinate gradually decreases, the area of the cursor movable region CT2 may be gradually reduced every time the z coordinate falls below any of the threshold values α. When n threshold values α are provided, the area of the cursor movable region CT2 can be changed in n + 1 stages.

  The STB 2 may have a specification in which the area of the cursor movable region CT2 is continuously changed as the z coordinate changes. An example of the STB 2 having such specifications will be described below as a second embodiment.

2. Second Embodiment Next, a second embodiment will be described. Note that the second embodiment is basically the same as the first embodiment except for the point related to the change in the area of the cursor movable region CT2. In the following description, emphasis is placed on the description of parts different from the first embodiment, and description of common parts may be omitted.

FIG. 6 schematically shows a change pattern of the area of the cursor movable region CT2 in the present embodiment. The variation range of the z coordinate in the present embodiment is from 0 (the position of the surface of the touch panel 11) to z _max . Note that z _max is the maximum value of the z coordinate that can be input using the touch panel 11, for example.

As shown in FIG. 6, when the z coordinate is z _max , the STB 2 sets the cursor movable region CT2 as a region having a width L _max and a height H _max . Further, when the z coordinate is 0, STB2 sets the cursor movable region CT2 as a region having a width L _min (<L _max ) and a height H _min (<H _max ).

When the z coordinate is z ₁ (where 0 <z ₁ <z _max ), the STB 2 sets the cursor movable region CT2 as a region having a width L ₁ and a height H ₁ . L ₁ and H ₁ are values determined according to the following equation (2).
L ₁ = L _min + (L _max −L _min ) × z ₁ / z _max
H ₁ = H _min + (H _max −H _min ) × z ₁ / z _max (2)

  In the present embodiment, the width and height of the cursor movable region CT2 are determined by the method described above. Therefore, the area of the cursor movable region CT2 is continuously changed with the change of the z coordinate. Thus, the user can finely adjust the area of the cursor movable region CT2 so that the cursor CS can be easily operated.

  In the present embodiment, as the z coordinate approaches the surface of the touch panel 11, the two-dimensional coordinates (x, y) and the position coordinates (X, Y) on the image P are reduced so that the area of the cursor movable region CT2 is reduced. The correspondence setting of is changed. Therefore, the user can intuitively adjust the area of the cursor movable region CT2.

3. Third Embodiment Next, a third embodiment will be described. The third embodiment is basically the same as the first embodiment except that the position of the cursor movable region CT2 is determined according to the position of the cursor CS. In the following description, emphasis is placed on the description of parts different from the first embodiment, and description of common parts may be omitted.

  In the present embodiment, when the area of the cursor movable region CT2 is reduced (for example, when shifting from the state of FIG. 3 to the state of FIG. 4), the position of the cursor movable region CT2 is the cursor CS at that time. It is decided according to the position.

  More specifically, as shown in FIG. 7, the position of the cursor movable region CT2 is determined such that the position of the cursor CS is at the center of the cursor movable region CT2. As a result, the operation of the cursor CS after the area of the cursor movable region CT2 is reduced becomes easy for the user.

  Note that how the position of the cursor movable region CT2 is determined is not limited to the above-described form, and various forms can be adopted in consideration of user operability and the like. For example, as shown in FIG. 8, the position of the cursor movable region CT2 may be determined such that the positional relationship between the cursor movable region CT2 and the cursor CS is saved before and after the reduction.

4). Fourth Embodiment Next, a fourth embodiment will be described. The fourth embodiment is basically the same as the first embodiment except that the cursor movable region CT2 is moved according to the operation. In the following description, emphasis is placed on the description of parts different from the first embodiment, and description of common parts may be omitted.

  In the present embodiment, when the user performs a predetermined cursor operation in a state where the area of the cursor movable region CT2 is reduced (for example, the state shown in FIG. 4), a process of moving the cursor movable region CT2 (hereinafter referred to as convenience). (Referred to as “movement process”). Details of this movement process will be described below with reference to FIG.

  FIG. 9A illustrates a state where the area of the cursor movable region CT2 is reduced. A constant region (colored portion in the figure) near the outer edge in the cursor movable region CT2 is set as a region X for receiving an instruction to execute the movement process.

  More specifically, when the cursor CS stays at any position in the area X for a certain period of time, the cursor is movable by a predetermined distance in the direction corresponding to that position (the direction indicated by the dotted arrow in the figure). CT2 is set to move. Thereby, the user can move the cursor movable region CT2 in a desired direction by performing an operation of moving the cursor CS in the region X. At this time, the area of the cursor movable region CT2 is not changed.

  For example, when the user wants to move the cursor movable region CT2 in the lower left direction, as shown in FIG. 9B, the user moves the cursor CS to a position in the region X that is closer to the lower left of the cursor movable region CT2. Move. As a result, as shown in FIG. 9C, the object of moving the cursor movable region CT2 in the lower left direction is achieved.

  The moving process described above is an example of a process for moving the position of the cursor movable region CT2 on the image P according to a predetermined condition. As specific forms of the processing, various forms can be adopted in consideration of user operability and the like in addition to the form of movement processing performed in the present embodiment.

5. Others As described above, the remote control device 1 (input device) accepts input of three-dimensional coordinates and gives three-dimensional coordinate information (x, y, z) to the STB 2 (information processing device). As a result, the STB 2 acquires three-dimensional coordinate information (x, y, z) from the remote control device 1.

  In addition to the form of acquiring the coordinate information (x, y, z) in this way, the STB 2 also has a function of accepting, for example, a three-dimensional coordinate input, and acquires the coordinate information (x, y, z) alone. You may come to do.

  The STB 2 includes a correspondence setting unit 26 and a cursor position specifying unit 27. The correspondence setting unit 26 has two-dimensional coordinates (x, y) corresponding to the two-direction coordinates (x coordinate and y coordinate) in the coordinate information and a position (X, Y) on the image P (on a predetermined target). Set the correspondence with. The cursor position specifying unit 27 specifies the position based on the setting of the correspondence relationship.

  Furthermore, the correspondence setting unit 26 changes the setting of the correspondence according to the coordinates (z coordinate) in the remaining one direction in the coordinate information. Therefore, according to STB2, it is possible to easily perform fine operations and the like without requiring partial enlarged display of an image.

  In addition, the STB 2 superimposes the cursor CS, which is display information (more specifically, a graphic indicating the specified position) corresponding to the specific result, on the image P. Thereby, the specific result can be reflected in the image P.

  The correspondence setting unit 26 sets the correspondence so that the region (cursor movable region CT2) on the image P corresponding to the fluctuation range (inputable region CT1) of the two-dimensional coordinates (x, y) is determined. To do. Then, the cursor position specifying unit 27 changes the setting of the correspondence relationship so that the area of the cursor movable region CT2 changes.
