When the display device according to the present invention has such a content reproduction function, the display device may not include a configuration for connecting to an external source device.

(First embodiment)
FIG. 1 is a block diagram showing a configuration example of a display device according to the first embodiment of the present invention.
As illustrated in FIG. 1, the display device 1 according to the present embodiment includes a control unit 10 and a display unit 13, and includes a touch sensor 12 and an operation unit 14 as the operation input unit. Note that only one of the touch sensor 12 and the operation unit 14 may be provided as the operation input unit. In addition, the display device 1 illustrated in FIG. 1 includes a communication unit 11 for communicating with an external source device.

  The display unit 13 includes a display panel that displays an image. Examples of the display panel include various display panels such as a liquid crystal display and an organic electroluminescence display. The communication unit 11 is a communication interface for communicating with an external source device in a wired or wireless manner. Various communication interfaces corresponding to communication standards can also be applied.

  The control unit 10 controls the entire display device 1. The control unit 10 operates the program stored in the program storage area and performs various controls. For example, the control unit 10 includes a central processing unit (CPU) or a micro processing unit (MPU), a RAM (Random Access Memory) as a work area, and a control device such as a storage device. / It can also be mounted as an IC chip set.

  This storage device includes a control program (including a program for executing display change processing according to the present invention), a UI (User Interface) image for displaying as an OSD (On Screen Display) image, various setting contents, and the like. Remembered. Examples of the storage device include a flash ROM (Read Only Memory) and an EEPROM (Electrically Erasable and Programmable ROM). Depending on the type of the display device 1, an HDD (Hard Disk Drive) may be employed as the storage device.

  The touch sensor 12 is a sensor that detects a touch operation on the display area (all display areas) of the display unit 13 by the user. For example, a surface type or projection type electrostatic capacity method, electromagnetic induction method, infrared method, surface Various types of sensors such as an elastic wave method and a resistive film method can be applied. The touch sensor 12 is often provided as a panel so as to overlap the surface of the display unit (display panel) 13, and is also referred to as a touch panel alone or in combination with the display panel.

  When the touch sensor 12 detects a touch operation, the touch sensor 12 passes information (input coordinate information) for specifying a position where the touch operation is performed to the control unit 10, or the control unit 10 inputs a touch operation to the touch sensor 12 by a polling process or the like. To monitor. The touch sensor 12 and the part that controls the touch sensor 12 in the control unit 10 constitute a touch operation unit that receives a touch operation by the user. In response to detection of the touch operation input by the touch operation unit, the control unit 10 acquires the detected input coordinate information, determines which position on the display screen of the display unit 13 the input coordinate is, and Based on the determination result, processing corresponding to the display is performed on the display screen of the display unit 13.

  The operation unit 14 includes a pointing device that receives an operation input by a user in a state where a pointer is displayed on the display area of the display unit 13, and a reception unit that receives an operation signal from the pointing device by wire or wirelessly. Examples of pointing devices include a mouse, a joystick, a touch pad, and a trackball.

  Further, the display device 1 has hardware keys (operation buttons) such as a power key and a volume adjustment key (not shown), detects an operation input from the key, passes it to the control unit 10, and responds to the operation. The control unit 10 executes the process. For example, when the power key is pressed for a predetermined time (t seconds) or longer, the power is turned on or off. When the power key is pressed for less than t seconds, an OSD image showing an operation menu is read and superimposed on the display unit 13 and displayed. You may let them. What is necessary is just to accept various settings about the display apparatus 1 from the touch sensor 12 or the operation part 14 in the state which displayed this OSD image.

  Next, main features of the present invention will be described. First, the control unit 10 displays an image input from a different source device in each of the divided display areas obtained by dividing the display area of the display unit 13 (all display areas visible to the user) into two or more. Display control is performed as follows. This display control itself can be realized by an existing multi-screen display technique.

  As a main feature of the present invention, the control unit 10 receives a predetermined operation starting from a point on a line having a predetermined thickness including the boundary line between the divided display areas in such a state. The display control is performed so as to move the boundary line. Such display change processing will be described in detail.

  The term “on the line having the predetermined thickness” refers to the inside of a rectangle within a predetermined range (a predetermined width and preferably a predetermined range centered on the boundary line) sandwiching the boundary line. The determination of being a point on a line of a predetermined thickness including the boundary line (hereinafter referred to as determination I) is performed by using the vertical coordinate of the touched point in the horizontal direction when a vertical line boundary exists. Compared with the horizontal coordinate range of a line with a predetermined thickness including the boundary line, and if the coordinate is within the coordinate range, it is determined that the point is on the line with the predetermined thickness including the boundary line (recognition) )do it. Similarly, when there is a horizontal boundary line, the determination may be made by comparing the coordinates in the vertical direction based on the same concept.

  The reason why the determination is made not by the boundary line itself but by a line having a predetermined thickness including the boundary line is that it is difficult for the user to always specify the boundary line accurately, and the user tries to specify the boundary line. This is to widen the range considered to be operated.

  When the touch sensor 12 is used as the operation input unit, the predetermined operation indicates a predetermined touch operation. Whether or not the predetermined touch operation starting from the above point has been accepted may be determined on the control unit 10 side, but the touch sensor 12 may be configured to be performed by the touch sensor 12 itself. When the operation unit 14 is used as the operation input unit, the predetermined operation refers to a predetermined operation using a pointing device. It may be determined on the control unit 10 side whether or not the predetermined operation starting from the above point has been accepted.

  The determination of the predetermined operation (hereinafter referred to as determination II) depends on how the predetermined operation is defined. Next, this definition will be described with an example.

  As an example, the predetermined operation may be defined as a slide operation that designates the point and slides from the designated position in a direction substantially perpendicular to the boundary line. Here, the designation means designation by touching in the case of a touch operation, and designation by clicking one button provided in the case of an operation by a pointing device. This slide operation is an operation of moving and stopping without releasing the specified touch or clicked button, and is sometimes referred to as a swipe operation. In addition to this example, the touch may be performed with a user's finger or a touch pen.

  In this case, it is preferable that the control unit 10 performs display control so that the boundary line is moved in the vertical direction of the boundary line by the amount slid by the sliding operation. Instead, the control unit 10 may perform display control so that the boundary line is moved by a predetermined distance in the direction in which the sliding operation is received.

  Further, instead of the slide operation, the predetermined operation may be defined as a flick operation that designates the point and plays it in a direction substantially perpendicular to the boundary line from the designated position. This flick operation is an operation that is frequently used particularly for a touch operation, but can also be defined as an operation that stops a click while moving in the above-mentioned direction after specifying by a click in an operation with a pointing device. In this case, the control unit 10 may perform display control so that the boundary line is moved in the vertical direction of the boundary line by a predetermined distance.

  Supplementarily, the difference in the determination method between the slide operation and the flick operation will be described. Here, the touch operation with the touch sensor 12 will be described as an example, but even the operation unit 14 is basically the same except that the designation by the touch is replaced with the designation by the click or the like. The description is omitted except for this.

  The distinction between the two can be determined by any one of, for example, (1) a touch period, (2) a touch start position, and (3) a rest period at the start of touch. In (1) above, if the period after the touch is moved in parallel and released until the touch is released is shorter than the first predetermined time, it is determined that the flick operation has been performed. It is determined that the slide operation has been performed up to the position where the touch is released.

  In (2) above, if a touch is started from a distance within a predetermined range from the boundary line including the boundary line, it is determined that a slide operation has been performed, and the predetermined thickness is determined. When a touch is started from a distance within the line and outside the predetermined range, it is determined that a flick operation has been performed.

  In (3) above, it is determined that the slide operation has been performed when the stationary state continues for the second predetermined time or longer at the start of touching, and when the stationary operation is not performed at the start of touching (less than the second predetermined time). It is determined that the operation is a flick operation. However, regarding an example of the touch operation, for example, in Windows 7 or later, since a long press touch is assigned to a right click operation by a pointing device such as a mouse, when it is determined as a slide operation in (3) above (and a flick operation) In the case of determination), it is preferable to display the determination result by OSD display or the like. In the example of the designation operation by clicking or the like, a slide operation or a flick operation may be accepted for an operation of a button other than the right click operation.

  Next, display control for moving the boundary line will be described with reference to FIGS. 2, 3A, and 3B, taking an actual use scene as an example. Here, the touch operation with the touch sensor 12 will be described as an example. However, even with the operation unit 14, the designation by touch is replaced with the designation by clicking a button or the like. The description is omitted except for the part.

  2 is a diagram illustrating an example of a state in which the boundary line is touched in the two-screen display state that is a state before the display change process in the display device of FIG. 1, and FIG. 3A illustrates another example of the state. FIG. Moreover, FIG. 3B is a figure which shows an example of the 2 screen display after performing a display change process with respect to the display apparatus of FIG. 2 or FIG. 3A. 2 and 3A, the bezel portion 17 is also illustrated. The bezel portion 17 is a frame provided around the display portion 13, and can basically be said to be a frame (outer edge) for disposing the display portion 13 in the cabinet of the display device 1.

  As described above, each of the images displayed in the divided display area is an image input from a different source device. The display device 1 illustrated in FIG. 1 receives a total of two images, a first image and a second image. In particular, as shown in FIG. 2, the first image 20a is input from the PC 4p, the second image 20b is input from the smartphone 4s, and the first image 20a and the second image 20b are displayed in different divided display areas. Take the scene that is being taken as an example.

  The second image 20b is the same image as the image 46a displayed on the display unit 46 of the smartphone 4s. In addition, the display device 1 illustrated in FIG. 2 is connected to both the PC 4p and the smartphone 4s with two cables. One of them is a cable for transmitting an image, and the other one is a cable for transmitting information of a user operation such as a touch operation by the touch operation unit to the source device side.

  Examples of the former cable include a cable of a High-Definition Multimedia Interface (HDMI: registered trademark, hereinafter the same) standard and a Mobile High-definition Link (MHL: registered trademark, the same applies below) standard. As the latter cable, for example, a cable of Universal Serial Bus (USB: registered trademark, hereinafter the same) standard can be mentioned. 3A to 3E omit the illustration of the source device. When connecting wirelessly, for example, a Miracast compatible HDMI adapter, a WiFi (registered trademark) wireless device, or the like may be mounted on the display device 1 or the source device.

  In the example of FIG. 2, there are two divided display areas on the left and right, and the boundary line is in the vertical direction. FIG. 2 shows an example in which a slide operation is performed on the boundary line. Compared with the example of FIG. 2, the example of FIG. 3A displays a pointer 21 indicating that the boundary line is movable when a line with a predetermined thickness including the boundary line is touched. The only difference is that In other words, the pointer 21 is a cursor icon for clearly entering the screen composition ratio change mode. Of course, in the slide operation and the flick operation, when a point on the line having a predetermined thickness including the boundary line is touched, the pointer 21 is displayed on the line, and reception on the pointer 21 is started at that stage. Also good. After the touch is released, a slide operation or a flick operation is performed and the boundary line is moved, or when a second touch is performed again or when a predetermined time has elapsed, the display of the pointer 21 may be deleted. .

  By displaying such a pointer 21, the user can be informed that the boundary line can be moved. In the case of an operation using a pointing device instead of a touch operation, the normal pointer may be changed to the pointer 21 as described above.

  As shown in FIG. 2 or FIG. 3A, when the user performs a slide operation to the left with a finger F starting from a point on a line having a predetermined thickness including the boundary line between the divided display areas, the touch sensor 12 Then, the control unit 10 performs display control so as to move the boundary line by the amount of sliding as shown in FIG. 3B.

  Here, moving the boundary line means that the control unit 10 recognizes the boundary line and changes the ratio between the divided display areas in the direction perpendicular to the boundary line (in this example, the horizontal direction). Means. In the example of changing the display state from FIG. 2 or FIG. 3A to FIG. 3B, the first image 20a is reduced in the horizontal direction to become the first image 20c, and the second image 20b is enlarged in the horizontal direction to obtain the second image 20d. It has become. In this example, the control unit 10 maintains the aspect ratio of the size of the image displayed in each of the divided display areas before and after the movement of the boundary line (before and after the change of the size of the divided display area). It is changed by reduction / enlargement processing (scaling processing). In addition to such scaling processing, black band addition or black band removal processing may be performed as necessary.

  The simultaneous change of the screen size during the two-screen display is conventionally adjusted with the left and right keys from a menu or the like, but in the present embodiment, this adjustment is performed as a boundary line as illustrated in FIG. 2 or FIGS. 3A and 3B. Is performed by a touch operation (boundary line touch) on a line having a predetermined thickness including Thereby, in this embodiment, it is possible to change the ratio of two screens that are excellent in visual and sensation.

  As an alternative process, the control unit 10 changes the size of the image displayed in each of the divided display areas before and after the movement of the boundary line by changing the display range without changing the scale. Also good. Changing the display range without changing the scale means that the display image is partially hidden from the state before the movement or the hidden portion is displayed. In this case as well, black band addition or black band removal processing may be performed as necessary.

  As described above, in the display device 1 according to the present embodiment, it is possible to display images input from different source devices in each of the divided display areas obtained by dividing the display unit 13 and is troublesome. Thus, the size of the divided display area can be changed (adjusted) by an intuitive operation without requiring an operation. In other words, in this embodiment, the display change process for changing the size ratio between the divided display areas is a predetermined operation starting from a point on a line having a predetermined thickness including the boundary line. Therefore, operability is improved because it can be realized by an operation that matches the user's intention.

  Although the display change process of the present invention including this embodiment has been described on the assumption that the divided display area is rectangular, the vertical display range is not limited to the rectangular display area. As long as the horizontal range is known, the same display change process can be executed by treating the four sides of the range as the boundary line. In addition, in the display change process of the present invention including this embodiment, the timing between the touch operation or the operation by the pointing device and the display change process corresponding thereto, that is, the interval for executing the display change process may be arbitrarily determined. .

(Second Embodiment)
A second embodiment of the present invention will be described with reference to FIGS. 3C, 3D, and 4 together. FIG. 4 is a flowchart for explaining an example of the display change process in the display device according to the second embodiment of the present invention. 3C is a diagram showing an example of a single screen display (full screen display) state that is a state before the display change process in the display device of FIG. 1, and is a diagram for explaining the display change process of FIG. is there. 3D is a diagram illustrating an example of a three-screen display after the display change process is performed on the display device in FIG. 3B, and FIG. 3E is a display change process performed on the display device in FIG. 3B. It is a figure which shows the other example of subsequent 3 screen display.

  Although the present embodiment will be described with a focus on differences from the first embodiment, various application examples described in the first embodiment can be similarly applied. For example, in this embodiment, a touch operation with the touch sensor 12 will be described as an example. However, even with the operation unit 14 which is an example of another operation input unit, designation by touch is designation by clicking a button or the like. This is basically the same only by replacing it with, and the description thereof is omitted.

  In addition to the display change process (referred to as the first display change process) in the first embodiment, the control unit 10 in the present embodiment also performs a display change process (referred to as the second display change process) described below. .

  In the second display change process, an image different from the image displayed on the display unit 13 (display region of the display unit 13) (one image or each image of the divided display region) can be input to the display device 1. In this state, the touch sensor 12 starts from a point on a boundary line between the display unit 13 (the display region) and the bezel portion 17 (that is, a line having a predetermined thickness including four outer frame line segments of the display region). It is executed when a predetermined operation (predetermined touch operation) is received.

  Here, the input possible state is a state in which one image (first image 20e) is displayed in the display area as illustrated in FIG. Indicates a state in which another image (second image 46 a) has been input to the display device 1. As described above, it is desirable that the input state is an actually input state, but it is only necessary to be able to input according to an input instruction from the control unit 10.

  Further, the boundary line here refers to any of the four sides (the outer frame line segment of the display area) indicating the display area of the display unit 13. For example, as shown in FIG. 3C, when a predetermined touch operation starting from a point on the boundary line (side) on the right side of the display device 1 is received, the second display change process is performed. Further, as the predetermined touch operation, a slide operation or a flick operation in a direction substantially perpendicular to a boundary line existing between the bezel portion 17 and the display area can be applied.

  Further, the line having a predetermined thickness here refers to the inside of a rectangle within a predetermined range (basically, a predetermined range inward from the outer edge of the display area) including the boundary line. However, in the case of a projection-type capacitive touch sensor, the touch may be detected even by the bezel portion 17, so that the predetermined range including the portion outside the outer edge of the display area is used. It may be left.

  In the second display change process, the control unit 10 generates a new divided display area so as to move the boundary line, and displays the other image in the newly generated divided display area. Take control.

  With reference to FIGS. 3C and 3B, an example in which the slide operation is adopted as the predetermined touch operation will be described. In the state where the first image 20e is displayed as shown in FIG. 3C, the user performs the above slide operation starting from a point on a line of a predetermined thickness including the boundary line (side) on the right side of the display device 1 with the finger F. If it is detected, the touch sensor 12 detects it and passes it to the control unit 10. The control unit 10 moves the boundary line by the amount of the slide to generate one new divided display area, and displays the other image (second image 46a that can be input) in the new divided display area. Display control.

  For example, when the user slides to the position of the finger F illustrated in FIG. 3B, the control unit 10 reduces the first image 20e displayed in the original display area as illustrated in FIG. 3B and reduces the first image 20c. The second image 20d obtained by enlarging the second image 46a is displayed in the new divided display area.

  Conversely, when the touch sensor 12 detects the slide operation starting from a point on a line having a predetermined thickness including the left side, the control unit 10 displays the second image 20d on the left side and displays the first image on the right side. The image 20c is displayed. Further, when the slide operation starting from a point on a line having a predetermined thickness including a horizontal boundary line (upper side or lower side) is received, the control unit 10 similarly sets the boundary line in the vertical direction. The display control may be performed to display the other image in a new divided display area.

  Here, even when the image displayed in the display area is composed of a plurality of images displayed in each of the divided display areas, the other image is displayed in a divided display area different from the entire image. Display it. As a result, the entire image is also reduced as a whole by a scaling process or the like. At this time, the entire image may be subjected to scaling processing for each divided display area of each image.

  Such processing will be described with reference to FIGS. 3B and 3D, taking an example in which the slide operation is adopted as the predetermined touch operation. In the state where the first image 20c and the second image 20d are displayed on the two screens as in the display state of FIG. 3B, the user positions the finger F illustrated in FIG. 3D from the boundary line between the right bezel portion 17 and the display area. When the slide operation is performed, the touch sensor 12 detects it and passes it to the control unit 10. This sliding operation is a sliding operation toward the inner direction perpendicular to the right side of the display area.

  The control unit 10 reduces the first image 20c and the second image 20d displayed in the original display area as shown in FIG. 3D to display the first image 20f and the second image 20g, respectively, and displays a new divided display. The third image 20h is displayed in the area. Note that the third image 20h is an image obtained by performing scaling processing or the like on an image input from a source device different from the PC 4p or the smartphone 4s in FIG. 3A as necessary.

  Conversely, when the touch sensor 12 detects a slide operation starting from the boundary line between the left bezel portion 17 and the display area, the control unit 10 displays the third image 20h on the left side and the first image on the right side. 20f is displayed, and the second image 20g is further displayed on the right side thereof.

  In addition, when the slide operation starting from a point on the boundary line between the upper or lower bezel portion 17 and the display area is received, the control unit 10 similarly moves the side (boundary line) to perform a new division. Display control for displaying the other image in the display area may be performed. For example, when the slide operation starts from a point on the boundary line with the upper bezel portion 17, the third image 20h is displayed on the upper side, and the first image 20f and the second image 20g are arranged on the lower side. Display it.

  Thus, even when the image displayed in the display area is composed of a plurality of images displayed in each of the divided display areas, the other image is displayed in a separate display area different from the entire image. May be displayed. However, it is also possible to move only a part of the boundary line (side) and not perform a scaling process on a certain divided display area.

  Such processing will be described with reference to FIGS. 3B and 3E, taking an example in which the slide operation is adopted as the predetermined touch operation. A case where the user slides the finger F as illustrated in FIG. 3E in the display state of FIG. 3B and a state where a new image (image 20k in FIG. 3E) is input will be described.

  In this case, the control unit 10 displays the second image 20d as it is among the first image 20c and the second image 20d displayed in the original display area (denoted as the second image 20j in FIG. 3E), and A first image 20i obtained by reducing one image 20c is displayed, and a third image 20k is displayed in a new divided display area generated by the reduction. As described above, when the vertically long image 20d and the horizontally long image 20c are displayed in the original display area, and another image 20k to be newly displayed is horizontally long, the vertically long image 20d is converted into a scaling process or the like. What is necessary is just to display as it is, without giving.

  Further, the image to be reduced may be specified as the image closest to the position of the slide operation regardless of the landscape orientation or portrait orientation. The display change process from the state shown in FIG. 3B to the state shown in FIG. 3E can also be realized by such a process.

  An example of display control (drawing control) when a touch on a boundary line is detected will be described with reference to FIG. Here, for simplification of explanation, a slide operation is adopted as the predetermined touch operation, and the display device 1 will be described as being capable of displaying either full screen display or two screen display.

  First, the control unit 10 determines whether or not a boundary touch has occurred based on the detection result from the touch sensor 12 (step S1). When the boundary touch has occurred (YES in step S1), the control unit 10 checks the current screen configuration and determines whether the screen configuration is a two-screen configuration (step S2).

  If it is not a two-screen configuration (NO in step S2), that is, if it is a full-screen display (single-screen display), the control unit 10 can input another image for a two-screen configuration. It is confirmed whether there is another source device (step S3). If there is nothing else (NO in step S3), the control unit 10 treats the boundary touch operation accepted in step S1 as invalid, returns to step S1, and waits for the next boundary touch.

  In the case of YES in step S2, the control unit 10 displays an arrow clearly indicating the boundary line change start (that is, entering the screen composition ratio change mode) such as the pointer 21 in FIG. 3B (step S4), and then accepts it. The amount of movement of the boundary line is detected from the amount of movement of the arrow (step S5).

  Thereafter, the control unit 10 calculates the ratio of the divided display area (two screens) from the movement amount detected in step S5, that is, the end position of the slide operation in the boundary touch (step S6), and performs scaling processing based on the ratio. By performing the above, each screen is reconstructed (display change processing) (step S7). Further, if YES in step S3, that is, if a two-screen configuration is possible, the processes in steps S4 to S7 are executed.

  Further, in the second display change process in the present embodiment, when the flick operation is adopted as the predetermined touch operation, the side (boundary line) is moved by a predetermined distance as in the first display change process. A new divided display area may be generated and the other image may be displayed in the new divided display area.

  As described above, in the display device 1 according to the present embodiment, the display change process for increasing a new divided display area is also performed visually and sensibly by a predetermined touch operation starting from a point on the boundary line. Since it can be realized by a touch operation that matches the intention, the operability is improved.

  Conversely, in the display state of FIG. 3B, when the user slides the finger F from the position shown in FIG. 3B to the right bezel portion 17 in the right direction, the touch sensor 12 detects it, The control unit 10 may perform display control so that one divided display area is deleted as in the display state of FIG. 3C, and as a result, only the first image 20e may be displayed. Similarly, in the display state of FIG. 3D, when the user slides the finger F to the right from the position of the boundary line shown in FIG. 3D, the touch sensor 12 detects that, and the control unit 10 detects that in FIG. As in the display state, display control may be performed so as to delete the divided display area on the right side of the position of the boundary line, and as a result, only the first image 20c and the second image 20d may be displayed.

  That is, when the touch sensor 12 receives the slide operation (slide operation in a direction substantially perpendicular to the boundary line) starting from a point on a line having a predetermined thickness including the boundary line between the divided display areas, the boundary line is Display control is performed so as to move, and finally the touch sensor 12 accepts the slide operation to reach a point on a line of a predetermined thickness including the boundary line between the display unit 13 (the display region) and the bezel unit 17. In such a case, the display control is performed so that the boundary line is moved to the bezel portion 17 and the divided display area is deleted.

  Also, such deletion can be performed by a flick operation instead of a slide operation. Specifically, in the first display change process in the first embodiment, the touch sensor 12 starts a flick operation (substantially perpendicular to the boundary line) starting from a point on a line having a predetermined thickness including the boundary line between the divided display areas. When the control unit 10 accepts a direction flick operation), the control unit 10 may perform display control so as to move the boundary line to the bezel unit 17 and delete the divided display area. That is, in the first display change process, if the predetermined distance is set as the distance from the boundary line to the bezel portion 17, the display change process from the display state of FIG. 3B to the display state of FIG. Display change processing from the 3D display state to the display state of FIG. 3B can be realized.

(Third embodiment)
A third embodiment of the present invention will be described. In this embodiment, the predetermined touch operation for performing the first display change process in the first embodiment and the second display change process in the second embodiment is other than the slide operation and the flick operation. A certain pinch-out operation or pinch-in operation is adopted.

  Although the present embodiment will be described with a focus on differences from the first embodiment, various application examples described in the first embodiment can be similarly applied. However, the present embodiment is an example of a pinch-out operation or a pinch-in operation, and is basically a process for a touch operation with the touch sensor 12 and is limited to a case where the touch sensor 12 is compatible with multi-touch. In order to cope with multi-touch, for example, a projection-type capacitive sensor or the like may be employed. Of course, even the operation unit 14 having a pointing device can be similarly applied if a pointing device is constructed or buttons are assigned so that a pinch-out operation and a pinch-in operation are possible.

  In the present embodiment, the predetermined touch operation is a pinch-out operation. This pinch-out operation is also called a stretch operation. A boundary line (a boundary line between divided display areas as in the first embodiment or a boundary line with the bezel portion 17 as in the second embodiment can be similarly applied. When the touch sensor 12 accepts an operation to open the two fingers so as to sandwich or cover a line having a predetermined thickness including), the control unit 10 performs a new division. Display control is performed so that a display area is generated and another image is displayed in the newly generated divided display area. However, as described in the second embodiment, it is necessary that an image different from the image displayed in the display area can be input to the display device.

  Further, in this embodiment, it is possible to cope with deletion of the divided display area. In that case, the predetermined touch operation may be a pinch-in operation. This pinch-in operation is also simply called a pinch operation. About two boundary lines, each boundary line (even if it is a boundary line between divided display areas as in the first embodiment, the boundary line with the bezel portion 17 as in the second embodiment) If the touch sensor 12 accepts an operation to close the two fingers after touching a line with a predetermined thickness including the same), the control unit 10 Display control is performed so that the divided display area surrounded by the book boundary is deleted and only the remaining image is displayed.

  Here, it supplements about the process of the black belt part in this embodiment and 1st, 2nd embodiment. 3B, FIG. 3D, and FIG. 3E, as to which black belt portion the black belt portion is attached to when the image is displayed (that is, to which image it belongs) And the divided display area including the black belt portion is determined based on the determination result, and the boundary line between the divided display areas may be determined. As an alternative process, the divided display area may be defined excluding the black belt portion, and the black belt portion may be treated as the “line of a predetermined thickness including the boundary line”. In that case, regarding the black belt portion, the center line in the width direction is treated as a boundary line, and the width of the black belt is adopted as the predetermined thickness (the predetermined thickness is changed according to the width of the black belt portion). You can do it.

(Fourth embodiment)
A fourth embodiment of the present invention will be described with reference to FIG. FIG. 5 is a functional block diagram showing a configuration example of a display device according to the fourth embodiment of the present invention. The display device 5 illustrated in FIG. 5 can be said to be a detailed configuration example of the display device 1 of FIG. 1 and can be applied to any of the first to third embodiments. In this embodiment, the touch operation with the touch sensor 12 will be described as an example, but the operation unit 14 which is an example of another operation input unit is basically the same, and the description thereof is omitted. .

  The display system illustrated in FIG. 5 can perform two-screen display on the display device 5 using video output from the PC 4p and the smartphone 4s. The display device 5 includes a control unit 50 corresponding to the control unit 10 of the display device 1, a touch panel 54 corresponding to the touch sensor 12, and a display unit 53 corresponding to the display unit 13. As for the communication unit corresponding to the communication unit 11 of the display device 1, only the connection cable is illustrated in the display device 5.

  The control unit 50 includes a display control unit 51 and a touch panel control unit 52. In addition, the display control unit 51 includes an input video processing unit 51a, a screen configuration construction unit 51b, and a display processing unit 51c. The touch panel control unit 52 includes a touch event detection unit 52a, a touch event control unit 52b, a touch event transmission unit 52c, and a selector 52d.

  Moreover, PC4p illustrated in FIG. 2 and the smart phone 4s are each connected to the display apparatus 5 with the said connection cable. The PC 4p includes a main control unit 41p, a display control unit 42p, and a cursor control unit 45 that control the whole. The smartphone 4s includes a main control unit 41s, a display control unit 42s, a display unit 46, and a touch panel control unit 47 that control the whole. The display control unit 42p has a video processing unit 43p and an output processing unit 44p, and the display control unit 42s has a video processing unit 43s and an output processing unit 44s.

  First, video output from the PC 4p and the smartphone 4s will be described. In the PC 4p, the video processing unit 43p performs various video processing on the video to be output to the display device 5, and the output processing unit 44p performs processing to output the video after video processing via the connection cable. . The cursor control unit 45 controls the movement of the cursor position in the video. The cursor control unit 45 can be incorporated as a part of the operation system (OS) of the PC 4p.

  Similarly, in the smartphone 4s, the video processing unit 43s performs various video processing on the video to be output to the display device 5, and the output processing unit 44s outputs the video after video processing via a connection cable. Perform the process. The video processing in the video processing units 43p and 43s may include processing for correcting video color, video rotation processing, video scaling processing, processing for adding / removing a black band portion from the video, and the like.

  In addition, the smartphone 4s can display the video output from the display control unit 42s on the display unit 46, and the display unit 46 includes a touch panel (not shown). This touch operation on the touch panel is also accepted by the touch panel control unit 47 described later, and processing according to the touch operation information (input coordinate information and the like) is executed. The touch panel control unit 47 can be incorporated as a part of the operation system (OS) of the smartphone 4s. Of course, the PC 4p may be provided with a similar display unit (and touch panel).

  The input video processing unit 51a performs video processing such as processing for correcting the color of the video on the video input from the PC 4p or the smartphone 4s, and outputs the video processing to the screen configuration building unit 51b. However, this video processing may not be performed for a video that is not finally displayed on the display unit 53.

  The screen configuration building unit 51b selects a video input from the PC 4p or the smartphone 4s as appropriate based on an instruction from the touch event control unit 52b, which will be described later, performs a scaling process, and builds a screen configuration such as combining two screens. The video processing is performed and output to the display processing unit 51c. This video processing can include processing for adding / removing a black belt portion from the video. The display processing unit 51c performs processing for causing the display unit 53 to display the video output from the screen configuration construction unit 51b. As a result, an image is displayed in the display area of the display unit 53.

  Processing when the touch panel 54 is touched in the display area with respect to the video displayed in this way will be described. When a touch operation is performed on the display area, the touch panel 54 passes information (input coordinate information) for specifying a position where the touch operation is performed to the touch event detection unit 52a. The touch event detection unit 52a detects information indicating what kind of operation (touch event) the touch operation is, for example, information indicating a slide operation, a flick operation, or the like. The determination relating to this detection corresponds to the above-described determination II. The touch event detection unit 52a passes the input coordinate information and the information (hereinafter collectively referred to as touch information) to the touch event control unit 52b.

  The touch event control unit 52b determines whether the touch information is information on the PC 4p or the smartphone 4s based on the current screen information constructed by the screen configuration construction unit 51b and the input coordinate information. The input coordinate information is passed to the touch event transmission unit 52c together with information on the current screen constructed by the screen configuration construction unit 51b, which is the determination result.

  When the determination result is PC4p, the touch event transmission unit 52c instructs the selector 52d to match (switch) the instruction destination so that the instruction can be transmitted to the PC4p side, and then transmits the touch information to the PC4p. Upon receiving the touch information, the PC 4p performs processing such as the cursor control unit 45 moving the position of the cursor as indicated by the touch information, designating and inverting the character selection range, and moving the icon. Then, the processed video is reflected by the video processing unit 43p and finally reflected as a display video on the display unit 53.

  On the other hand, when the determination result is the smartphone 4s, the touch event transmission unit 52c instructs the selector 52d to match (switch) the instruction destination so that the instruction can be transmitted to the smartphone 4s side, and then to the smartphone 4s. Send touch information. The smartphone 4s that has received the touch information performs processing such as the touch panel control unit 47 moving the touch position as indicated by the touch information, designating the character selection range to invert, and moving the icon. Then, the processed video is reflected by the video processing unit 43p and finally reflected as a display video on the display unit 53.

  In addition, when the split display of two or more split displays is performed, the touch event control unit 52b is based on the touch information, and the touch information is from a point on a line having a predetermined thickness including the boundary line between the split display areas. It is determined whether or not a predetermined touch operation is started. This determination corresponds to the above-described determination I.

  As the predetermined touch operation, a case will be described in which a slide operation for sliding in a direction substantially perpendicular to the boundary line is employed. If the touch event control unit 52b starts from the above point and determines that it is such a slide operation, the touch event control unit 52b only slides from the information indicating the target boundary line and the information indicating the slide amount. The display ratio of each divided display area is calculated so as to move the boundary line, and is passed to the screen configuration construction unit 51b together with information indicating the target boundary line. At this time, instructions such as addition / removal of a black belt may be given to the screen configuration construction unit 51b as necessary. After that, the image of the result of moving the boundary line is displayed on the display unit 53 by the screen configuration building process in the screen configuration building unit 51b and the display process in the display processing unit 51c.

  A case where a flick operation that flicks the boundary line in a direction substantially perpendicular to the boundary line is employed as the predetermined touch operation will be described. If the touch event control unit 52b determines that the flick operation starts from the above point, the touch event control unit 52b moves the boundary line by a predetermined distance from the information indicating the target boundary line and the information indicating the predetermined distance. The display ratio of each divided display area is calculated so as to be transferred to the screen configuration construction unit 51b together with information indicating the target boundary line. At this time, instructions such as addition / removal of a black belt may be given to the screen configuration construction unit 51b as necessary. After that, the image of the result of moving the boundary line is displayed on the display unit 53 by the screen configuration building process in the screen configuration building unit 51b and the display process in the display processing unit 51c.

  Here, for the sake of simplification of explanation, the case where only the first display change process is executed has been described. When other display change processing is also employed, for example, whether or not the touch event control unit 52b indicates a predetermined touch operation that is accepted when executing the employed display change processing based on the touch information. The calculation is performed to move the boundary line as necessary (calculation of the display ratio of each divided display area), and the calculation result is displayed on the screen together with the information indicating the target boundary line. What is necessary is just to pass to the construction part 51b.
