Embodiment 1
Hereinafter, an STB (set top box) 1 according to a first embodiment of the present invention will be described in detail with reference to FIG. FIG. 1 is a block diagram showing the configuration of the STB 1 according to this embodiment.

(About the configuration of STB1)
As shown in FIG. 1, the STB 1 according to this embodiment includes a CPU (Central Processing Unit) 11, a program execution unit 12, a memory 13, a communication control unit 14, an operation signal reception unit 15, an input switching detection unit 16, and a control signal. A transmission unit 17, a position information acquisition unit 18, and a correction unit 19 are provided. The STB 1 is connected to a TV (display device) 2 capable of displaying an image (TV image or also referred to as a first image) obtained by receiving a broadcast wave.

  The CPU 11 controls the operation of the entire STB 1 by transmitting a control signal to each unit included in the STB 1. The memory 13 stores one or a plurality of programs and setting data for the STB 1. The program execution unit 12 refers to the memory 13 and executes one or more programs. The program execution unit 12 supplies an image (also referred to as an STB image or a second image) obtained by executing one or more programs to the TV 2. Note that the one or more programs stored in the memory 13 include an OS for operating the STB 1.

  The communication control unit 14 is connected to a communication network such as a telephone line, a LAN (Local Area Network), and a wireless LAN via a network terminal (not shown). The communication network is not particularly limited as long as it can transmit and receive data. The communication control unit 14 transmits and receives various data through the communication network. Specifically, a program executed by the program execution unit 12 or an image to be displayed on the TV 2 is downloaded and stored in the memory 13. The communication control unit 14 transmits data such as a search character string to the communication network. The communication control unit 14 may be configured to download the program or image from the communication network in a streaming format without storing the program or image in the memory 13.

  The operation signal reception unit 15 receives an operation signal indicating an operation performed on the STB 1 by the user, and transmits the received operation signal to the CPU 11 and the input switching detection unit 16. The operation signal received by the operation signal receiving unit 15 may be, for example, an operation signal transmitted from an STB remote controller (also called a remote controller) that transmits an operation signal for the STB 1. Moreover, the operation signal transmitted from TV remote control which transmits the operation signal to TV2 may be sufficient. In particular, when the STB 1 and the TV 2 are HDMI-connected, the signal transmitted from the TV remote controller is transferred to the operation signal receiving unit 15 using the remote control pass-through that is one of the functions of CEC. be able to.

  The input switching detection unit 16 detects an input switching signal indicating input switching of the TV 2 among the operation signals received by the operation signal receiving unit 15. Specifically, an input switching signal indicating switching from the TV image to the STB image or switching from the STB image to the TV image is detected. When the input switching detection unit 16 detects the input switching signal, the input switching detection unit 16 transmits a notification indicating that the input switching signal has been detected to the control signal transmission unit 17.

  The control signal transmission unit 17 transmits a control signal for controlling the TV 2 to the TV 2 based on the notification received from the input switching detection unit 16.

  More specifically, the input switching detection unit 16 detects an input switching signal indicating that the image input to the TV 2 is switched from the TV image to the STB image among the operation signals received from the operation signal receiving unit 15, and performs control. A notification indicating that the input switching signal has been detected is transmitted to the signal transmission unit 17. The control signal transmission unit 17 that has received the notification transmits to the TV 2 a PinP start signal (superimposed display start signal) that is a control signal indicating that PinP display of the TV image and the STB image is started. The input switching detection unit 16 detects an input switching signal indicating that the image input to the TV 2 is switched from the STB image to the TV image among the operation signals received from the operation signal reception unit 15, and the control signal transmission unit 17. A notification indicating that the input switching signal has been detected is transmitted. The control signal transmission unit 17 that has received the notification transmits to the TV 2 a PinP cancellation signal (superimposed display cancellation signal) that is a control signal indicating that the PinP display of the TV image and the STB image is cancelled.

  With the above configuration, the STB 1 can automatically start or cancel the PinP display when detecting the input switching to the TV 2.

  The position information acquisition unit 18 transmits position information indicating the display position of the TV image to be superimposed and displayed on the TV 2 when the notification indicating that the operation signal reception unit 15 starts the superimposed display is received from the TV 2. Instruct. In addition, when the position information acquisition unit 18 receives position information from the TV 2, the position information acquisition unit 18 stores the position information in the memory 13 via the CPU 11.

  Note that the position information acquired by the position information acquisition unit 18 includes coordinate information of at least one vertex of the TV image displayed on the PinP by the TV 2, and the vertical and horizontal widths of the TV image with the vertex as the starting point. You may add the value which shows. The coordinate information may be coordinate information on the xy plane by defining an x-axis and a y-axis that are orthogonal to each other with either one of the center or vertex of the image display area of the TV 2 as the origin. For example, the variable indicating the x coordinate is X, the variable indicating the y coordinate is Y, the variable indicating the vertical width starting from (X, Y) is H, and the variable indicating the horizontal width starting from (X, Y) is W. The position information may be defined by four variables X, Y, H, and W. Further, the position information is obtained by using two coordinate information of the coordinates (X1, Y1) of any vertex of the TV image displayed in PinP and the coordinates (X2, Y2) of the vertex facing the vertex (X1, Y1). Also good.

  Further, when the display size of the TV image displayed on the Pin 2 by the TV 2 is determined in advance and the display position of the TV image displayed on the PinP is limited to a plurality of predetermined display positions, the position information is further added. It can be simplified. That is, the position information indicating the plurality of predetermined display positions is stored in the STB 1 and a position number corresponding to the position information is determined in advance. The position information acquisition unit 18 may be configured to acquire the position information by acquiring the position number from the TV 2. For example, when the display position when the TV 2 displays the TV image in PinP is only either the lower right or the lower left of the display area, the position information acquisition unit 18 sets 0 or 0 associated with the lower right or the lower left, respectively. Only numeric data such as 1 is acquired as position information. In this case, the amount of data acquired by the position information acquisition unit 18 from the TV 2 can be reduced.

  Based on the position information acquired by the position information acquisition unit 18, the correction unit 19 does not overlap an object (for example, an icon or a widget) included in the STB image acquired from the program execution unit 12 with the TV image displayed on PinP. As described above, the display position of the object is corrected, and a new STB image is generated. The correction unit 19 supplies the generated new STB image to the TV 2. Details of the STB image correction processing performed by the correction unit 19 will be described later.

  The correction unit 19 determines whether the object overlaps the TV image based on the position information acquired by the position information acquisition unit 18, and corrects the display position of the object only when the object overlaps. Also good. Moreover, in this embodiment, although the correction | amendment part 19 demonstrates the structure which correct | amends an STB image and produces | generates a new image, this invention is not limited to this. For example, the correction unit 19 may be configured to transmit an operation signal indicating that the display position of the object is moved to the program execution unit 12 so that the object does not overlap the TV image.

  The TV 2 is a display device that can display an image (TV image) obtained by receiving broadcast waves. In this embodiment, a case where a TV is used as the display device will be described. However, the display device is not particularly limited as long as it is configured to display an image obtained by receiving broadcast waves.

The area 22 may be displayed.

(About the object display position correction process)
FIG. 3C is a diagram showing an example of an image displayed on the TV 2 in a state where the TV 2 displays the image shown in FIG. 3A on the screen display area 21. As shown in FIG. 3C, when the TV 2 displays the TV screen display area 22 in the PinP display, the STB 1 defines the area where the TV screen display area 22 is displayed in the STB image as the TV image prohibited area 250. Set as. The STB 1 moves the display position of the icon 24 a overlapping the set TV image prohibited area 250 so as not to overlap the TV image prohibited area 250.

In order to specifically implement the embodiments described herein,
(Case 1) When STB1 is configured to display a plurality of objects (icons, widgets, etc.) so as not to overlap each other, and (Case 2), STB1 does not overlap a plurality of objects (icons, widgets, etc.) with each other It is possible to assume both cases when not configured to display in this way. Here, with the configuration shown in FIG. 3C, even in the case 2 described above, the icon 24a and the TV screen display area 22 can be displayed so as not to overlap. As another example of the process for correcting the display position of the object, a process as shown in FIG. 3D may be performed (corresponding to the case 1).

  FIG. 3D shows a case where the TV 2 displays the PinP display of the STB image and the TV image while the TV 2 displays the image shown in FIG. 3A in the screen display area 21. It is the figure which showed an example of the image to do. As shown in FIG. 3D, when the TV screen display area 22 is PinP-displayed so that the TV 2 overlaps the icon 24a, the STB 1 displays the same display position and display size as the TV screen display area 22 in the STB image. The TV image widget 25 is arranged. The TV image widget 25 is one of the objects included in the STB image supplied from the STB 1 to the TV 2 and is an area for displaying a blank. Normally, a plurality of objects included in the STB image are configured so as not to overlap each other. Therefore, the TV image widget 25 is positioned at a position where the STB 1 overlaps the TV screen display area 22 displayed in the PinP on the STB image. Can be displayed so that the icon 24a and the TV screen display area 22 do not overlap. That is, the TV image widget 25 is an area where the placement of objects included in the STB image such as the icon 24 is prohibited.

  In order to display the TV image widget 25 on the STB image, the STB 1 receives a notification indicating that the TV 2 starts PinP display of the STB image and the TV image from the TV 2. When STB1 and TV2 are HDMI-connected, an operation signal indicating the start of PinP display transmitted from the TV remote controller is received using the remote control pass-through which is one of the functions of CEC.

Subsequently, the program execution unit 12 modifies the STB image supplied to the TV 2 so as to move the display position of the object based on the operation signal received in step S109.

(Step S111)
Subsequently, the program execution unit 12 supplies the TV 2 with the STB image in which the display position of the object is corrected in step S110.

(Step S112)
Subsequently, the TV 2 displays the STB image supplied from the STB 1 in the screen display area 21 in step S111.

(Regarding problems with conventional technology)
As described above, in the prior art, when PinP display is performed after the switching operation to the STB image, there is a possibility that an image as shown in (b) or (c) of FIG. 3 is displayed. In this case, it is necessary to move (correct) the object so as not to overlap the TV screen display area 22 by an input operation from the user with respect to the object displayed overlapping the TV screen display area 22. For this reason, there is a problem that a complicated operation by the user may occur when using the PinP display of the STB image and the TV image.

(About the object position correction procedure in this embodiment)
Next, with reference to FIG. 5, a description will be given of a procedure for correcting the position of an object displayed by the STB 1 so as to overlap the TV image when the TV 2 performs the PinP display of the STB image and the TV image in the present embodiment. FIG. 5 is a sequence diagram for explaining a procedure for the STB 1 to correct the display image when the TV 2 in the present embodiment starts or cancels the PinP display.

(Steps S201 to S206)
First, as in step S101 in FIG. 4, the TV 2 displays a TV image in the screen display area 21. The subsequent processing from step S202 to step S206 (processing until the TV 2 displays the STB image) is also the same as the processing from step S102 to step S106 described with reference to FIG. .

(Step S207)
Subsequently, the operation signal receiving unit 15 receives an operation signal indicating an operation for starting PinP display from the TV remote controller. In the present embodiment, the case where the operation signal receiving unit 15 receives an operation signal from the TV remote controller will be described. However, this does not specify the present invention, and the operation signal receiving unit 15 receives the operation signal from the STB remote controller. It is good also as a structure which receives. When the operation signal receiving unit 15 receives an operation signal from the STB remote controller, the processes in steps S208 and S209 are omitted.

(Step S208)
Subsequently, the TV 2 that has received the operation signal indicating the operation of starting the PinP display in step S207 transmits a notification indicating that the PinP display is started to the STB 1. In step S202, when the input switching detection unit 16 detects the input switching signal and the control signal transmission unit 17 transmits the PinP start signal to the TV 2, the TV 2 transmits the PinP start signal. It is good also as a notice of starting PinP display.

(Step S209)
Subsequently, the STB 1 receives a notification indicating that the PinP display transmitted from the TV 2 is started in step S208.

(Step S210)
Subsequently, when the STB 1 receives a notification indicating that the PinP display starts from the TV 2 in Step S209, the position information acquisition unit 18 displays the position information indicating the display position of the TV screen display area 22 when the PinP is displayed on the TV 2. Instructs TV 2 to transmit.

(Step S211)
Subsequently, the TV 2 receives the position information transmission instruction transmitted from the position information acquisition unit 18 in step S210.

(Step S212)
Subsequently, the TV 2 that has received the position information transmission instruction transmitted from the position information acquisition unit 18 in step S <b> 211 transmits position information indicating the display position of the TV screen display area 22 to the position information acquisition unit 18.

(Step S213)
Subsequently, the position information acquisition unit 18 acquires position information indicating the display position of the TV screen display area 22 transmitted from the TV 2 in step S212.

(Step S214)
Subsequently, based on the position information acquired in step S213, the correcting unit 19 determines whether the display position of the TV screen display area 22 overlaps any one of the plurality of objects included in the STB image. Determine whether or not. When the correction unit 19 determines that no object overlaps the TV screen display area 22, the STB 1 proceeds to the process of step S216, and when the correction unit 19 determines that any object overlaps. Advances to the process of step S215.

(Step S215)
Subsequently, the correction unit 19 corrects the display position of the object determined to overlap with the display position of the TV screen display area 22 in step S215 so as not to overlap the display position of the TV screen display area 22.

(Step S216)
Subsequently, when the correction unit 19 determines that no object overlaps the TV screen display area 22 in step S214, the correction unit 19 corrects the STB image acquired from the program execution unit 12. Instead, the STB image is supplied to the TV 2. When the correction unit 19 corrects the display position of the object of the STB image in step S215, the correction unit 19 supplies the corrected STB image to the TV 2.

(Step S217)
Subsequently, the TV 2 displays the STB image supplied from the STB 1 in the step S 216 in the screen display area 21 and displays the TV image in the TV screen display area 22.

  Through the processing up to step S217, the STB 1 automatically corrects the STB image when the STB image and the TV image are displayed in PinP. In the following steps, a process for returning the object whose display position has been corrected in step S215 to the original position when the TV 2 cancels the PinP display will be described.

(Step S218)
Subsequently, the TV 2 receives an operation signal indicating an operation for canceling the PinP display from the TV remote controller.

(Step S219)
Subsequently, the TV 2 that has received the operation signal indicating the operation of canceling the PinP display in Step S218 transmits a notification indicating that the PinP display is cancelled, to the STB1. Further, the display of the TV screen display area 22 which has been displayed in PinP is canceled.

(Step S220)
Subsequently, the STB 1 receives a notification indicating that the PinP display transmitted from the TV 2 is canceled in step S219.

(Step S221)
Subsequently, in step S215, the correction unit 19 determines whether or not the correction unit 19 has corrected the display position of any of the plurality of objects included in the STB image. If the correction unit 19 determines in step S215 that none of the objects has corrected the display position, the STB 1 ends the process. If the correction unit 19 determines in step S215 that the display position of any object has been corrected, the STB 1 proceeds to the process of step S222.

(Step S222)
Subsequently, the correcting unit 19 returns the display position of the object determined to have corrected the display position in step S221 to the original position. At this time, as an example of a method for returning the display position to the original display position, when the correction unit 19 corrects the display position of the object in step S215, the correction unit 19 indicates that the object has been corrected. A method for storing the correction information in the memory 13 is exemplified. Specifically, the correction unit 19 associates position information indicating the original display position of the object with object information indicating the object, and stores the information in the memory 13 as correction information. In step S222, the correction unit 19 refers to the correction information stored in the memory 13, and corrects the STB image so as to return the object to the original display position. Further, instead of the position information indicating the original display position of the object, movement information indicating the movement amount of the object at the time of correction in step S215 may be used.

(Step S223)
Subsequently, the correction unit 19 supplies the STB image in which the display position of the object is corrected to the TV 2 in step S222.

(Step S224)
Subsequently, the TV 2 displays the STB image supplied from the STB 1 in the screen display area 21 in step S223.

  Through the processes from step S218 to step S224, the STB 1 automatically corrects the STB image when canceling the PinP display of the STB image and the TV image.

  Note that when the TV 2 notifies the STB 1 that the PinP display is started in step S208, the positional information may be transmitted together. In this case, the processing from step S209 to step S212 can be omitted.

(Advantages of STB1)
As described above, the STB 1 is an STB that supplies an STB image obtained by executing one or a plurality of programs to the TV 2 that can display a TV image obtained by receiving a broadcast wave. A position information acquisition unit 18 (corresponding to “position information acquisition means” in the claims) that acquires position information indicating a display position of a TV image when a TV image and an STB image are displayed in PinP, and the position information Based on the above, a correction unit 19 that corrects the display position of at least one of the one or more objects included in the STB image so that the object does not overlap the TV image (see “Correcting means in claims”) ”).

  The position information acquisition unit 18 of the STB 1 acquires position information indicating the display position of the TV screen display area 22 from the TV 2 when the TV 2 starts PinP display of the STB image and the TV image. Based on the position information acquired by the position information acquisition unit 18, the correction unit 19 automatically corrects the display position of the object displayed overlapping the TV screen display area 22 among the plurality of objects included in the STB image. To do.

  With the above configuration, when the TV 2 starts PinP display of the STB image and the TV image, only the object overlapping the TV image among the objects included in the STB image can be automatically moved. The operation by is not necessary.

  Therefore, the STB 1 can reduce troublesome operations by the user when using the PinP display using the STB 1 and the TV 2.

  In addition, when the STB 1 does not have the configuration for sending the position information transmission instruction to the display device in step S210, the user may set the display position and the display size of the TV image widget 25 in advance. . That is, when the STB 1 receives a notification that the PinP display starts from the TV 2, the correction unit 19 displays the TV image widget 25 at a predetermined display position. The correcting unit 19 corrects the display position of the object that overlaps the predetermined display position. Therefore, even when the TV image to be displayed in PinP and the object included in the STB image are overlapped and displayed by the above processing, the STB 1 can automatically correct the display position of the object.

  Further, even when the TV 2 does not have the configuration for transmitting the position information in step S212, the user may set the display position and display size of the TV image widget 25 in advance. Also in the above case, the STB 1 can perform the same processing and automatically correct the display position of the object.

(Appendix 1)
In the present embodiment, STB1 is a dongle type, and the case where it is connected to the HDMI connection terminal of TV2 has been described. However, the present invention is not limited to this. For example, a configuration similar to that of the STB 1 in the present embodiment may be built in the TV remote controller. In the above case, the connection between the STB 1 and the TV 2 can transmit and receive a CEC command by making a wireless connection such as Wireless HDMI, for example. The STB image is supplied from the program execution unit 12 to the TV 2 by using, for example, WiFi (registered trademark) Display. Similarly, a configuration similar to that of the STB 1 in the present embodiment may be built in a keyboard for performing an input operation to the TV 2. Also in the above case, the connection between the STB 1 and the TV 2 can transmit and receive CEC commands by wireless connection such as Wireless HDMI, for example. The STB image is supplied from the program execution unit 12 to the TV 2 by using, for example, WiFi (registered trademark) Display. In addition, since the size of the housing is larger when incorporated in a keyboard than when incorporated in a remote control, a D-sub 15 pin or HDMI terminal can be further provided for wired connection. Furthermore, a comfortable mouse operation becomes possible by mounting a touchpad on the keyboard.

[Embodiment 2]
Next, the display device 100 according to the second embodiment of the present invention will be described in detail with reference to FIG. For convenience of explanation, members having the same functions as those described in the embodiment are given the same reference numerals, and descriptions thereof are omitted. The display device 100 according to the present embodiment is different from the display device 100 according to the first embodiment in the processing performed by the correction unit 19.

(Example of processing performed by the correction unit 19)
An example of processing performed by the correction unit 19 according to the present embodiment will be described with reference to FIG. In the following description, among the objects included in the STB image, an object that overlaps the TV screen display area 22 and whose display position is to be corrected by the correcting unit 19 is also referred to as a “target object”. is there.

  FIG. 6 is a conceptual diagram for explaining an example of processing performed by the correction unit 19 included in the STB 1 according to the present embodiment.

  In the example illustrated in FIG. 6A, the correction unit 19 uses icons 24 a to c among the plurality of icons 24 included in the STB image based on the position information acquired from the position information acquisition unit 18. It is determined that the display area 22 overlaps. That is, the correction unit 19 specifies that the icons 24a to 24c are target objects.

  The correction unit 19 may correct the display positions of the icons 24a to 24c as shown in FIG. That is, as shown in FIG. 6B, the icons 24a to 24c identified as the target objects are moved in the same direction (in the example shown in FIG. 6B, rightward toward the display surface). Thus, the display positions of the icons 24a to 24c are corrected so that the icons 24a to 24c do not overlap the TV screen display area 22. Here, “move in the same direction” refers to, for example, a process of changing only one of the x-coordinate and y-coordinate indicating the display positions of the icons 24a to 24c.

  In general, objects arranged on the display screen are often arranged in order from the upper left toward the lower right toward the display screen. That is, the areas on the right side and the lower side toward the display screen are areas where no objects are arranged and there is a high possibility that space is available. In the example shown in FIG. 6A, by setting the right direction from the target object in advance as the same direction, the target object can be moved to an empty space. Therefore, the correction unit 19 suppresses the influence on the layout of the icons 24 other than the icons 24a to 24c, and sets the display positions of the icons 24a to 24c so that the icons 24a to 24c do not overlap the TV screen display area 22. It can be corrected.

  In the example shown in FIG. 6B, the right direction from the target object is set as the same direction in which the target object is moved. However, this is not intended to limit the present invention. Any direction may be set as the same direction.

  Further, it is preferable to determine the same direction by referring to the position information acquired from the position information acquisition unit 18 and the display position of one or more objects included in the STB image. The STB 1 determines in which of the vertical, horizontal, and horizontal areas the least number of objects are arranged with reference to the display position of the TV screen display area 22, and determines the direction in which the determined area exists. Set as the same direction.

  A specific example of the determination procedure will be described. As the coordinates indicating the position information, a case will be described in which x-axis and y-axis that are orthogonal to each other with the lower left corner as the origin toward the screen display area 21 are defined and coordinates on the xy plane are used. For example, when the coordinate indicating the display position of the object included in the STB image is (x1, y1) and the coordinate indicated by the position information acquired from the position information acquisition unit 18 is (x2, y2), X = x1-x2 and the difference Y = y1-y2 are calculated, respectively. When the difference X indicates a positive value, the object exists on the right side (x-axis positive direction side) of the TV screen display area 22, and when the difference X indicates a negative value, the object It can be determined that it exists on the left side (x-axis negative direction side) of the screen display area 22. Similarly, when the difference Y shows a positive value, the object exists above the TV screen display area 22 (y axis positive direction side), and when the difference Y shows a negative value, the object Can be determined to exist below the TV screen display area 22 (y-axis negative direction side). The correction unit 19 performs each of the objects included in the STB image of the above procedure. With the above procedure, the STB 1 can calculate the number of objects existing in each of the vertical and horizontal directions with reference to the display position of the TV screen display area 22.

  For example, when the number of objects arranged in the right area with respect to the display position of the TV screen display area 22 is the smallest, the STB 1 determines the right direction as the same direction. When the number of objects arranged in the lower area with respect to the display position of the TV screen display area 22 is the smallest, the STB 1 determines the downward direction as the same direction. That is, the STB 1 refers to the position information acquired from the position information acquisition unit 18 and the display position of one or more objects included in the STB image, and has the largest number of objects arranged with respect to the TV screen display area 22. A smaller direction is determined as the same direction. Accordingly, in the example shown in FIG. 6B, since the influence on the layout of other objects other than the target object can be suppressed, the user feels uncomfortable when the display position of the target object is corrected. Can be reduced.

  In the example shown in FIG. 6B, the correction unit 19 corrects the display positions of the icons 24a to 24c so as to maintain the relative positional relationship between the icons 24a to 24c that are target objects. Is preferred.

  When the display positions of the icons 24a to 24c are corrected, it may be difficult for the user to immediately grasp the new display position of the corrected target object. Therefore, the user is forced to bear a burden for searching for the corrected target object.

  According to the above configuration, the display position of the plurality of target objects is corrected while maintaining the relative positional relationship between the plurality of target objects, so that the burden for the user to search for the corrected target objects is reduced. Can be reduced.

  Further, the correcting unit 19 may correct the display positions of the icons 24a to 24c as shown in FIG. As shown in FIG. 6C, the correction unit 19 moves the icons 24a, 24b, and 24c upward, rightward, and downward, respectively, by moving the icons 24a, 24b, and 24c. The display positions of the icons 24 a to 24 c are corrected so that the icons c do not overlap the TV screen display area 22. Specifically, the correction unit 19 calculates the distance between the center coordinates indicating the center of the icon 24 a specified as the target object and each side of the TV screen display area 22. The correction unit 19 moves the icon 24a in the direction where the calculated shortest side exists (in the example shown in FIG. 6C, the upward direction). The correction unit 19 performs the same process for the icons 24b and 24c. When correcting the display position of the target object, it is desirable that the movement distance of the target object is the shortest so that the user can easily grasp the new display position of the corrected target object. In particular, when using a display device with a large screen, if the target object is moved to a position beyond the range of the user's field of view, the user may lose sight of the corrected target object. obtain.

  In the example shown in FIG. 6C, the target object can be moved in the direction in which the distance between the target object and each side of the TV screen display area 22 is the shortest. Therefore, STB1 has been corrected. The burden for the user to search for the target object can be reduced.

  Furthermore, the correcting unit 19 may correct the display positions of the icons 24a to 24c as shown in FIG. In the example shown in (d) of FIG. 6, the correction unit 19 moves the icons 24 a to 24 c similarly to the example shown in (c) of FIG. 6, and further, the outer edges of the icons 24 a to 24 c and the TV screen display area 22. The display positions of the icons 24a to 24c are corrected so that the sides of the icons are in contact with each other.

  When the user is watching for a long time after the display positions of the icons 24a to 24c are corrected by the correction unit 19, the user determines which icon 24 is the icon 24 whose display position has been corrected. It can happen that you forget it.

  In the example shown in FIG. 6D, the display positions of the icons 24a to 24c are corrected so that the outer edges of the icons 24a to 24c whose display positions are corrected and the sides of the TV screen display area 22 are in contact with each other. It is possible to clearly indicate which of the icons 24 included in the STB image is the icon 24 whose display position has been corrected by the correction unit 19.

  Therefore, in the example shown in FIG. 6D, the STB 1 can further reduce the burden for the user to search for the corrected target object.

  Furthermore, the correction unit 19 may correct the display positions of the icons 24a to 24c as shown in FIG. In the example shown in (e) of FIG. 6, the correction unit 19 moves the icons 24 a to 24 c as in the example shown in (c) of FIG. 6, and further displays the image with an inclination in the display surface. The display positions of the icons 24a to 24c are corrected.

  In the example shown in (e) of FIG. 6, any of the icons 24 included in the STB image is displayed by displaying the icons 24a to 24c whose display positions are corrected with an inclination in the display surface. Whether the icon 24 has the display position corrected by the correcting unit 19 can be clearly indicated.

  Therefore, in the example shown in FIG. 6E, the STB 1 can further reduce the burden for the user to search for the corrected target object.

(Modification of processing performed by the correction unit 19)
Subsequently, a modified example of processing performed by the correction unit 19 according to the present embodiment will be described with reference to FIGS. 7 and 8 are conceptual diagrams for explaining another example of processing performed by the correction unit 19 included in the STB 1 according to the present embodiment. In the example shown in FIGS. 7 and 8, the target object is moved in the same direction as shown in FIG. 6B, and the right direction from the target object is set as the same direction. A modification of the above case will be described.

  In the example shown in (a) of FIG. 7, based on the position information acquired from the position information acquisition unit 18, the correction unit 19 includes icons 24 a to 24 c among the plurality of icons 24 included in the STB image. Is identified. As shown to (a) of FIG. 7, the icons 24d-f which are other objects exist in the right direction of the icons 24a-c which are the movement destinations of the icons 24a-c. As shown in FIG. 7B, the correcting unit 19 secures a space for moving the icons 24a to 24c by moving the icons 24d to 24f in the right direction set as the same direction. The correction unit 19 moves the icons 24a to 24c to the secured space, so that the icons 24a to 24c are not displayed on the TV screen display area 22 and the icons 24d to 24f. To correct.

  As an example of specific processing performed by the correction unit 19, the correction unit 19 is based on position information acquired from the position information acquisition unit 18 and position information indicating display positions of a plurality of objects included in the STB image. It is determined whether another object exists in the movement destination (right direction) of the icons 24a to 24c that are target objects. When it is determined that there is no other object at the movement destination of the icons 24a to 24c, the correction unit 19 performs the same process as the process illustrated in FIG. When it is determined that there are other objects (icons 24d to f) at the destinations of the icons 24a to 24c, the icons 24a to 24c and the icons 24a to c are moved by moving the icons 24a to 24c to the right. It is determined whether or not 24d to f overlap. When it is determined that the icons 24a to 24c do not overlap with the icons 24d to 24f, the correction unit 19 moves the icons 24a to 24c to the right, so that the icons 24a to 24c are displayed on the TV screen display area 22 and The display positions of the icons 24a to 24c are corrected so as not to overlap any of the icons 24d to 24f. When it is determined that the icons 24a to 24c overlap with the icons 24d to f, the correcting unit 19 moves the icons 24d to f in the right direction, thereby creating a space for moving the icons 24a to 24c. It is determined whether it can be secured. In the calculation of the space in the example shown in FIG. 7, for example, the distance between the right side of the TV screen display area 22 and the right side of the screen display area 21, the display position of another object existing at the destination, and the object Calculate based on the size. If it is determined that a space for moving all the icons 24a to 24c can be secured, the correcting unit 19 moves the icons 24d to 24f to the right and moves the icons 24a to 24c to the right. By doing so, the display positions of the icons 24a to 24c are corrected so that the icons 24a to 24c do not overlap any of the TV screen display region 22 and the icons 24d to 24f. Processing when it is determined that a space for moving all the icons 24a to 24c cannot be secured will be described later with reference to another drawing.

  Therefore, in the example shown in FIG. 7, as a result of moving the target object in the same direction, other objects existing at the destination and the moved target object are prevented from being displayed so as to overlap each other. be able to.

  Moreover, it is preferable that the correction part 19 corrects the display position of icon 24a-c so that the relative positional relationship between the icons 24a-c which are object objects may be maintained.

  When the display positions of the icons 24a to 24c are corrected, it may be difficult for the user to immediately grasp the new display position of the corrected target object. Therefore, the user is forced to bear a burden for searching for the corrected target object.

  Therefore, in the example shown in FIG. 7, the STB 1 corrects the display position of the plurality of target objects while maintaining the relative positional relationship between the plurality of target objects. The burden for searching can be reduced.

  Next, processing in a case where it is determined that a space for moving all the icons 24a to 24c in the example illustrated in FIG. 7 cannot be secured will be described with reference to FIG. In the example shown in FIG. 8A, as in FIG. 7A, there are other objects at the destinations of the icons 24a to 24c (the right direction of the icons 24a to 24c) as the target objects. Icons 24d to f exist. Whether or not the correction unit 19 can secure a space for moving all the icons 24a to 24c by moving the icons 24d to f in the right direction by the same procedure as in the example shown in FIG. Determine. In the example shown in FIG. 8A, the correction unit 19 determines that a space for moving all the icons 24a to 24c cannot be secured. In the above case, the correction unit 19 generates a folder 24g that is an object in which some or all of the icons 24a to 24c are collected, and determines whether or not a space for displaying the generated folder 24g can be secured. To do. As shown in FIG. 8B, when it is determined that the space for displaying the folder 24g can be secured, the correction unit 19 secures the space by moving the icons 24d to 24f to the right. The generated folder 24g is displayed in the reserved space, and the icon 24c is moved rightward. Through the above processing, the correction unit 19 corrects the display position of the icon 24 so that the folder 24g and the icon 24c do not overlap the TV screen display area 22 and any of the icons 24d to f.

  Therefore, in the example shown in FIG. 8, the STB 1 displays that the target object moved in the same direction is displayed so that the other target object existing at the destination and the moved target object overlap. Can be prevented.

(Appendix 2)
In the first and second embodiments, the “first image” has been described as an image obtained by receiving a broadcast wave. However, this does not limit the above-described embodiment. For example, the TV 2 may be configured to display an image indicated by an image signal supplied from an external device as a “first image”.

Next, the display device 100 according to the third embodiment of the present invention will be described in detail with reference to FIG. For convenience of explanation, members having the same functions as those described in the embodiment are given the same reference numerals, and descriptions thereof are omitted.

  The display device 100 according to the present embodiment is a display device that includes each unit included in the STB 1 and the TV 2 according to the first embodiment. As illustrated in FIG. 9, the display device 100 includes a program execution unit 12, a memory 13, a communication control unit 14, an operation signal reception unit 15, an input switching detection unit 16, a control signal transmission unit 17, a position information acquisition unit 18, a correction. A unit 19, an image control unit 30, an antenna 31, a tuner unit 32, an image control unit 33, a superimposed display processing unit 34, and a display unit 35 are provided.

  The image control unit 30 controls the program execution unit 12, the memory 13, the communication control unit 14, the operation signal reception unit 15, the input switching detection unit 16, the control signal transmission unit 17, the position information acquisition unit 18, and the correction unit 19. The operation of each unit is controlled by transmitting.

  The antenna 31 is a receiving means for receiving broadcast waves. The broadcast wave received by the antenna 31 is supplied to the tuner unit 32.
