Description of the Related Art Conventionally, a plurality of image display devices and an image output device that outputs image information relating to each image display device are provided, and by combining partial images displayed on a plurality of screens of each image display device, 1 Multi-display systems that display two images are known. Examples of such an image display device include projectors and various displays such as liquid crystal. Examples of the image output device include a PC (Personal Computer).

By the way, in such a multi-display system, during image display, a screen (display area) in which the user's line of sight is not directed, or a screen (display area) where no active object (for example, window area) is arranged. However, in such a case, there is a problem that power consumption increases. On the other hand, there is known a control method for turning off the power of the image display device when an input operation to a pointing device such as a mouse is not performed for a predetermined time. In such a control method, an observer observes. Nevertheless, there is a problem that the power of the image display device is turned off.
In order to solve such a problem, a power saving control method is known in which a user's line-of-sight direction is detected and power-saving control of the image display apparatus is performed according to the line-of-sight direction (see, for example, Patent Document 1).

  In the power saving control method described in Patent Document 1, a user's face is captured as video data by a CCD camera, and the information processing apparatus uses the video data (the direction of the user's pupil, the direction of the face, and the use position). The user's gaze position is specified. Then, based on the line-of-sight position, the information processing apparatus turns off the power of the display device related to the display screen that the user has determined not to watch for a predetermined time or the backlight power of the display device. As a result, it is possible to save power of a display device that does not need to be displayed, and as a result, it is possible to save power of the entire multi-display system.

  However, the power saving control method described in Patent Document 1 requires a detecting means such as a CCD camera in order to detect the user's line-of-sight direction, which not only complicates the configuration but also makes the entire multi-display system expensive. There is a problem of becoming. In addition, since it is necessary to calculate a deviation based on the user's line-of-sight direction and a preset line-of-sight area, there is a problem that the processing becomes complicated.

  An object of the present invention is to provide a multi-display system, a display control method, a display control program, a recording medium, and an image output apparatus that can maintain a standby state in response to a user's unexpected operation.

  In order to achieve the above-described object, the multi-display system of the present invention forms a plurality of image display devices each having a screen for displaying an image according to input image information, and an image displayed on each screen. Forming a display image including the first object on a memory having a plurality of image forming areas, and displaying image information of the partial image related to the display image formed in each of the image forming areas. A multi-display system comprising: an image output device that outputs to each of the image display devices having the screen corresponding to the control device; and an operation device that operates the first object, wherein the image output device corresponds to the operation device. First object movement for moving the first object on the display image formed on the memory in response to an operation A standby state setting unit that sets the predetermined screen in a standby state, and another of the plurality of image forming areas that is adjacent to the screen where the first object is located and is set in the standby state In an image forming area corresponding to the screen, a buffer area setting unit that sets a buffer area in an area adjacent to the screen where the first object is located, and whether or not the first object has passed the buffer area a predetermined number of times And a standby set in the other screen corresponding to the image forming area having the buffer area when it is determined that the first object has passed the buffer area the predetermined number of times. And a first release unit for releasing the state.

When the elapsed time determination unit 5155 determines that the timer of the time measuring unit 5154 has timed up, the state setting unit 5156 sets the screen S related to the image forming area A that is the target of determination to the standby state. As a result, the image output unit 52 writes the image information in the image forming area A, and the image information output to the projector 8 related to the screen S corresponding to the image forming area A is stopped. In addition, the state setting unit 5156 determines that the target area determination unit 5153 has set the screen S corresponding to the image forming area A to be determined to be in a standby state and the image forming area A is activated. Then, the standby state set in the screen S is canceled. Thereby, image information output to the projector 8 related to the screen S is resumed.

  The target determination unit 5157 determines whether or not all the image forming areas A1 to A3 corresponding to the screens S1 to S3 have been set as determination targets. When the target determination unit 5157 determines that there is an image formation region A that is not set as a determination target, the next image formation region A, for example, the image formation region A1 is included in the determination target setting unit 5152 described above. If it is set as the determination target, the image forming area A2 is set as the determination target. Further, when it is determined that all the image forming areas A1 to A3 are set as the determination targets, that is, in the present embodiment, when the image forming area A3 is set as the determination target, the target determination unit 5157 The determination target setting unit 5152 sets the image forming area A1 as a determination target.

[Configuration of Standby State Canceling Unit 516]
FIG. 9 is a block diagram illustrating a configuration of the standby state canceling unit 516.
Returning to FIG. 7, when the pointer P and the active content area CA move, the standby state release unit 516 corresponds to the image forming area A that is the movement destination based on the movement trajectory of the pointer P and the content area CA. When the screen S is set to the standby state, the standby state is canceled. When a predetermined key on the keyboard 92 is input, the standby state set on the screen S corresponding to the image forming area A where the active content area CA is located is canceled. As shown in FIG. 9, the standby state release unit 516 includes an object movement release unit 5161 and a key input release unit 5162.

The target area setting unit 51611 sets the image forming area A corresponding to the screen S for determining whether or not to cancel the standby state. Specifically, the target area setting unit 51611 sets the image forming area A corresponding to another screen S adjacent to the screen S on which the pointer P is displayed as the target area. For example, when the pointer P is displayed on the screen S2, the target area setting unit 51611 sets the image forming areas A1 and A3 corresponding to the screens S1 and S3 adjacent to the screen S2 as the target area, and the pointer When P is displayed on the screen S1, the image forming area A2 corresponding to the screen S2 adjacent to the screen S1 is set as the target area.
When the active content area CA extends over all the screens S1 to S3, the target area setting unit 51611 does not set all the screens S1 to S3 to the standby state, and each screen S1 to S1. In S3, it is determined that all are active, the target area is not set, and the processing in the object movement release unit 5161 ends.

  The region state determination unit 51612 determines whether or not the screen S corresponding to the image forming region A set as the target region by the target region setting unit 51611 is set in the standby state by the standby state setting unit 515 described above. . When the target area setting unit 51611 sets a plurality of image forming areas A corresponding to a plurality of screens S as target areas, the area state determination unit 51612 displays screens corresponding to the respective image forming areas A. It is determined whether or not S is set in a standby state.

FIG. 10 is a diagram showing the buffer area BA set in the image forming areas A1 and A3 adjacent to the active screen S2 and corresponding to the standby screens S1 and S3. In FIG. 10, in order to make the position of the buffer area BA easy to understand, the buffer area BA is shown superimposed on the screens S1 and S3 corresponding to the image forming areas A1 and A3.
The buffer area setting unit 51613 is active in the image forming area A when the area state determining unit 51612 determines that the screen S corresponding to the target image forming area A is set in the standby state. A buffer area BA having a predetermined width is set in an area adjacent to the screen S. For example, when the active screen is the screen S2, the buffer area setting unit 51613 applies each of the areas adjacent to the screen S2 in the image forming areas A1 and A3, which are target areas, as shown in FIG. A buffer area BA having a width dimension of about 10% of the entire image forming areas A1, A3 is set. The ratio of the buffer area BA may be set as appropriate.

The movement determination unit 51614 determines whether or not the pointer P and the content area CA are moved by the user's operation on the mouse 91 and the keyboard 92.
The moving object determination unit 51615 determines whether the object to be moved by the operation of the user's mouse 91 and keyboard 92 is only the pointer P or includes the content area CA. Here, since the content area CA can be moved by the pointer P, for example, when it is dragged, the moving object determination unit 51615 determines whether the moving object is only the pointer P or the content area CA It is determined whether or not the area CA is included.

  The movement trajectory acquisition unit 51616 determines the trajectory of the moved object. Here, if the moving object determination unit 51615 determines that the content area CA has moved, the movement trajectory acquisition unit 51616 acquires the movement trajectory of the active content area CA and moves only the pointer P. If it is determined that, the movement locus of the pointer P is acquired.

The movement range determination unit 51617 determines the movement range of the object based on the movement locus of the object acquired by the movement locus acquisition unit 51616.
Specifically, the moving range determination unit 51617 uses the movement trajectory of the pointer P acquired by the movement trajectory acquisition unit 51616 when the moving object determination unit 51615 determines that the moved object is only the pointer P. Based on this, it is determined whether or not the pointer P has entered the buffer area BA of the image forming area A set as the target area.
The movement range determination unit 51617 is based on the movement locus of the content area CA acquired by the movement locus acquisition unit 51616 when the moving object determination unit 51615 determines that the moved object includes the content area CA. It is determined whether or not the content area CA is the target area and the buffer area BA of the image forming area A corresponding to the other screen S adjacent to the screen S where the content area CA is located has been entered. To do.

When the movement range determination unit 51617 determines that the pointer P has entered the buffer area BA, the movement locus determination unit 51618 determines whether or not the pointer P has passed the buffer area BA.
When the movement trajectory determination unit 51618 determines that the pointer P has passed the buffer area BA, the number determination unit 51619 determines whether the pointer P has passed the buffer area BA a predetermined number of times. The number of times is set to three in the present embodiment, but may be one, and the number may be set as appropriate.

  The state change unit 5161A corresponds to the first release unit, the second release unit, and the release unit of the present invention. When the number determination unit 51619 determines that the pointer P has passed the buffer area BA a predetermined number of times, and When the movement range determination unit 51617 determines that the content area CA has entered another image formation area A, the standby state of the screen S corresponding to the image formation area A into which the pointer P and the content area CA have entered Is released. As a result, the image information related to the screen S is output to the projector 8, and the partial image is displayed on the screen S.

  The cancellation determination unit 5161B determines whether there is a screen S whose standby state has been canceled by the state change unit 5161A. When the cancellation determination unit 5161B determines that there is a screen S in which the standby state is canceled, the acquisition of the current object position and the setting of the target area are performed again. On the other hand, when the cancellation determination unit 5161B determines that there is no screen S in which the standby state is canceled, the current object position is reacquired, but the target area is not reset. Thereby, even if the pointer P remains in the buffer area BA, it is determined whether or not the standby state is canceled for the screen S corresponding to the image forming area A in which the buffer area BA is set. Keep the target area set.

[Configuration of Key Input Canceling Unit 5162]
The key input release unit 5162 performs a predetermined input operation for switching the active content area CA on the display image T2 on the keyboard 92, for example, input of a function key or simultaneous input of a plurality of keys. When an operation signal corresponding to a predetermined input operation is input via the operation signal input unit 4, the standby state of the screen S corresponding to the image forming area A where the activated content area CA is located is canceled. The key input release unit 5162 includes a key input determination unit 51621, a target region setting unit 51622, a target region state determination unit 51623, and a target region release unit 51624.

The key input determination unit 51621 determines whether or not an operation signal corresponding to the predetermined input operation described above is included in the operation signals input to the operation signal input unit 4.
When the key input determination unit 51621 determines that the operation signal corresponding to the predetermined input operation is input, the target area setting unit 51622 positions the content area CA activated according to the input operation. An image forming area A to be set is set as a target area. Note that the position of the activated content area CA is acquired by the content position acquisition unit 5112 of the object position acquisition unit 511 described above.

The target area state determination unit 51623 determines whether or not the screen S corresponding to the image forming area A set as the target area is set in the standby state.
The target area release unit 51624 corresponds to the third release unit of the present invention, and the screen S corresponding to the image forming area A set as the target area is set in the standby state by the target area state determination unit 51623. When it is determined, the standby state of the screen S is canceled. Thereby, the image output of the partial image displayed on the screen S is resumed by the image output unit 52.

[Display control processing]
Hereinafter, the processes ST1, ST2, ST4, and ST5 constituting the display control process executed by the PC 2 that is the image output apparatus will be described. This display control process is executed by the control means 5 reading the program corresponding to each process ST1, ST2, ST4, ST5 from the storage means 6.

[Image display processing ST1]
FIG. 11 is a flowchart showing the process of the image display process ST1.
When displaying an image with MDS1, PC2 which is an image output apparatus performs image display process ST1. This image display processing ST1 is executed by the control means 5 reading the image display program stored in the storage means 6 of the PC 2, and the control means 5 is formed on the memory 53 in each projector 81-83. Image information related to the partial images T21 to T23 obtained by dividing the display image T2 is output, and the projectors 81 to 83 display the partial images T21 to T23 on the screens S1 to S3, respectively, thereby displaying the display image T2. It is processing to do.
In this image display processing ST1, as shown in FIG. 11, the division number acquisition unit 521 of the image output unit 52 constituting the control means 5 of the PC 2 sets the display image set by the division number setting unit 513 of the main control unit 51. The division number of T2, that is, the division number of the coordinate space of the memory 53 is acquired (step ST11).

Next, the display image dividing unit 522 divides the display image T2 by the acquired number of divisions (step ST12). In other words, in this embodiment, the display image dividing unit 522 sets the reading position of the display image T1 formed on the coordinate space of the memory 53, thereby setting the image forming areas A1 to A3 corresponding to the screens S1 to S3. Is specified.
Thereafter, the screen state determination unit 523 determines whether there is a screen set in the standby state among the screens S1 to S3 (step ST13).

If the screen state determination unit 523 determines that there is a screen set in the standby state, the partial image output unit 524 displays the image forming area A corresponding to the screen S set in the standby state. The image information written in the image forming area A corresponding to the screen S that is not set in the standby state is output to the projector 8 without outputting the image information written in (step ST14). Accordingly, among the projectors 81 to 83, the projector that has input image information displays a partial image related to the image information, and the projector that has not input image information does not perform image formation. Can be achieved.
On the other hand, when the screen state determination unit 523 determines that there is no screen set in the standby state, the partial image output unit 524 displays image information regarding all the partial images T21 to T23 as projectors 81 to 83. (Step ST15). Thereby, the display image T2 comprised by each partial image T21-T23 is displayed on the screen SC.

[Standby state setting process ST2]
Next, the standby state setting process ST2 will be described.
FIG. 12 is a flowchart showing the process of the standby state setting process ST2.
The standby state setting process ST2 is executed by the control unit 5 of the PC 2 reading out the standby state setting program stored in the storage unit 6, and each of the standby state setting processes ST2 is performed according to the position of the pointer P on the memory 53 and the active content area CA. This is a process of setting the screens S1 to S3 to the standby state. The image information related to the screen S set in the standby state by this processing ST2 is not transmitted and output to the projector 8 in the above-described image display processing ST1.
Specifically, in the standby state setting process ST2, as shown in FIG. 12, first, the division number acquisition unit 5151 of the standby state setting unit 515 constituting the main control unit 51 of the control means 5 is operated by the division number setting unit 513. The number of divisions of the set display image T2 is acquired (step ST21).

Next, the pointer position acquisition unit 5111 and the content position acquisition unit 5112 of the object position acquisition unit 511 acquire the position of the pointer P and the active content area CA, respectively (steps ST22 and ST23).
Thereafter, the determination target setting unit 5152 sets the image forming area A corresponding to the determination target screen S for determining whether or not to set the standby state (step ST24). In this stage, the determination target setting unit 5152 sets the image forming area A1 as a determination target.

Next, the target area determination unit 5153 determines whether the screen S corresponding to the image forming area A set as the determination target by the determination target setting unit 5152 is active (step ST25). Specifically, the target area determination unit 5153 has the pointer P or the active content area CA in the image forming area A based on the pointer P acquired by the object position acquisition unit 511 and the absolute coordinates of the content area CA. It is determined whether or not to do.
If the target area determination unit 5153 determines that the pointer P or the active content area CA exists in the determination target image forming area A, the screen S corresponding to the image forming area A is in a standby state. Is determined (step ST26). At this time, when the target area determination unit 5153 determines that the standby state is not set, the standby state setting unit 515 proceeds to step ST33.

  On the other hand, when the target area determination unit 5153 determines that the screen S corresponding to the image forming area A to be determined is set in the standby state, the standby state of the screen S is canceled (step ST27). Thereafter, the timer reset unit 514 resets the timer of the time measuring unit 5154 (step ST28), and the standby state setting unit 515 proceeds to step ST33.

In the determination in step ST25, if the target area determination unit 5153 determines that the pointer P and the active content area CA are not present in the determination target image forming area A, the elapsed time determination unit 5155 counts the time. It is determined whether the timer of unit 5154 is activated, that is, whether the timer is being monitored (step ST29).
When the elapsed time determination unit 5155 determines that the timer is not started in the determination in step ST29, that is, when it is determined that the timer is not being monitored, the timer related to the image forming area A to be determined. Is started, and the timer starts counting down from a predetermined time (step ST30).

On the other hand, in the determination in step ST29, when the elapsed time determination unit 5155 determines that the timer is activated, that is, when it is determined that the timer is being monitored, the elapsed time determination unit 5155 It is determined whether or not the timer has expired (step ST31). At this time, if the elapsed time determination unit 5155 determines that the time is not up, the standby state setting unit 515 proceeds to step ST33.
When the elapsed time determination unit 5155 determines that the time is up, the state setting unit 5156 sets the screen S corresponding to the image forming area A to be determined to be in a standby state (step ST32). Thereby, the image information related to the partial image to be displayed on the screen S is not transmitted and output from the image output unit 52 to the projector 8. Thereafter, the standby state setting unit 515 proceeds to step ST33.

In step ST33, the object determination unit 5157 determines whether or not all the image forming areas A1 to A3 corresponding to the partial images T21 to T23 constituting the display image T2 have been set as determination objects by the determination object setting unit 5152, that is, It is determined whether or not the above-described steps ST25 to ST33 have been executed for all the image forming areas A1 to A3 and the screens S1 to S3 corresponding to the image forming areas A1 to A3 (step ST33).
If the target determination unit 5157 determines that all the image forming areas A1 to A3 are set as determination targets by the determination target setting unit 5152, the process returns to step ST22, and the position of the pointer P and the active content area CA are returned. After the position is acquired, the determination target setting unit 5152 sets the image forming area A1 as a determination target, and executes the above-described steps ST25 to ST32.

On the other hand, when the target determination unit 5157 determines that there is an image formation region A that is not set as a determination target by the determination target setting unit 5152, the determination target setting unit 5152 determines the next image formation region A as a determination target. (Step ST34), and the above-described steps ST25 to ST32 are executed for the image forming area A and the screen S corresponding to the image forming area A.
Thus, the standby state setting process ST2 ends.

[Key input release process ST4]
Next, the key entry release process ST4 will be described.
FIG. 13 is a flowchart showing the process of the key entry release process ST4.
The key input release process ST4 is executed by the control means 5 processing the key input release program stored in the storage means 6 of the PC 2, and an input operation (input of a function key, When a plurality of keys are input at the same time, the content area CA selected in response to the key input operation is activated, and the screen corresponding to the image forming area A where the content area CA is located This is a process for canceling the standby state of S.

In the key input release process ST4, as shown in FIG. 13, first, the contents of the operation signal input from the keyboard 92 via the operation signal input unit 4 of the PC 2 are configured in the main control unit 51 of the PC 2. The key input determination unit 51621 of the key input release unit 5162 determines (step ST41). Specifically, the key input determination unit 51621 determines whether or not the operation signal includes a predetermined operation signal, that is, a signal for switching the selection state (active state) of the content area CA in the display image T2. Thus, it is determined whether or not a predetermined input operation has been performed on the keys of the keyboard 92.
If the key input determination unit 51621 determines that the predetermined operation signal is not input, the key input release unit 5162 ends the key input release processing ST4.

On the other hand, when the key input determination unit 51621 determines that the predetermined operation signal is input, the content position acquisition unit 5112 of the object position acquisition unit 511 is selected and activated by the user's input operation. The position of the content area CA is acquired (step ST42).
Next, the target area setting unit 51622 of the key input releasing unit 5162 determines the image forming area A of the memory 53 including the content area CA from the position (coordinates) of the content area CA acquired in step ST42. (Step ST43). Here, when the content area CA extends over a plurality of image forming areas A, the target area setting unit 51622 sets the plurality of image forming areas A as target areas.

Thereafter, the target area state determination unit 51623 determines whether or not the screen S corresponding to the image forming area A that is the target area set in step ST43 is set in the standby state (step ST44).
Here, when the target area state determination unit 51623 determines that the screen S is not set to the standby state, that is, the screen S is already active, the key input release unit 5162 The time release process ST4 is terminated.

On the other hand, when the target area state determination unit 51623 determines that the screen S is set in the standby state, the target area release unit 51624 waits for the screen S in which it is determined that the standby state is set. The state is released (step ST45). Thereby, the output of the image information related to the partial image to be displayed on the screen S set in the standby state is resumed by the image output unit 52, and the partial image is displayed by the projector 8.
In addition, the timer reset unit 514 resets the timer of the time measuring unit 5154 related to the image forming area A corresponding to the screen S (step ST46).
Thus, the key entry release process ST4 ends.

[Status monitoring process ST5]
Next, the state monitoring process ST5 will be described.
FIG. 14 shows a buffer area of the image forming area A3 corresponding to the screen S3 in which the pointer P located in the image forming area A2 is adjacent to the screen S2 corresponding to the image forming area A2 and is set in the standby state. It is a figure which shows the state which penetrate | invaded in BA. FIG. 15 is a diagram illustrating a state in which the pointer P has passed through the buffer area BA. FIG. 16 shows another example in which the active content area CA located in the image forming area A2 is adjacent to the screen S2 corresponding to the image forming area A2 and corresponds to the screen S3 set in the standby state. It is a figure which shows the state which penetrate | invaded in image formation area A3.
The state monitoring process ST5 is a process for canceling the standby state set in the divided screen corresponding to the movement destination of the object based on the movement locus of the object.

In this state monitoring process ST5, as shown in FIG. 14, an image forming area A (in FIG. 14, corresponding to another screen S that is adjacent to the screen S on which the pointer P is displayed and is set in the standby state). When the buffer area BA is set in the area adjacent to the screen where the pointer P is located in the image forming area A3), and the pointer P passes the buffer area BA a predetermined number of times as shown in FIG. Then, the standby state of the screen S corresponding to the image forming area A in which the buffer area BA is set is canceled.
In this state monitoring process ST5, as shown in FIG. 16, the active content area CA is an image forming area A (in FIG. 16, the image forming area A3 corresponding to the other screen S set in the standby state). ), The standby state of the other screen S is canceled. In this way, the image information of the partial image to be displayed on the other screen S from which the standby state is released is output to the projectors 81 to 83 by the image output unit 52.
Such a state monitoring process ST5 is executed when the control unit 5 of the PC 2 reads the state monitoring program stored in the storage unit 6.

FIG. 17 is a flowchart showing the process of the state monitoring process ST5.
Specifically, in the state monitoring process ST5, as shown in FIG. 17, first, the pointer position acquisition unit 5111 and the content position acquisition unit 5112 of the object position acquisition unit 511 perform the pointer P that is an object and the active content area CA. Each position is acquired (step ST51).
Next, the target area setting unit 51611 constituting the object movement time cancellation unit 5161 of the standby state cancellation unit 516 displays a screen adjacent to the screen S on which the partial image including the pointer P and the active content area CA is displayed. The corresponding image forming area A of the memory 53 is set as a target area (step ST52).

Thereafter, the area state determination unit 51612 determines whether or not the screen S corresponding to the image forming area A set as the target area is set in the standby state (step ST53).
Here, when the area state determination unit 51612 determines that the screen S is not set to the standby state, the object movement time cancellation unit 5161 returns to step ST51, and the pointer P and the active content area CA are displayed. Prepare to be moved. The reason for returning to step ST51 is to prepare for switching the active content area CA by the user's operation on the keyboard 92.
On the other hand, when the area state determination unit 51612 determines that the screen S is set in the standby state, the buffer area setting unit 51613 has the pointer P and the active content in the image forming area A that is the target area. The aforementioned buffer area BA is set in the area adjacent to the screen on which the area CA is displayed (step ST54).

Then, the movement determination unit 51614 determines whether or not at least one of the pointer P, which is an object, and the content area CA has been moved (step ST55).
At this time, if the movement determination unit 51614 determines that neither the pointer P nor the content area CA has moved, the movement determination unit 51614 returns to step ST51. As shown in the above-described key input release process ST4, when a predetermined input operation is performed on a key on the keyboard 92, it is assumed that the active content area CA has been switched, and the process proceeds to step ST51. Return.

  On the other hand, when the movement determining unit 51614 determines that these objects have been moved, the moving object determining unit 51615 determines whether the moved object is only the pointer P or includes the content area CA. (Step ST56). When the moving object determining unit 51615 determines that only the pointer P has moved, the object moving time canceling unit 5161 executes the pointer moving time process ST6 and determines that the content area CA has moved. The object movement release unit 5161 executes the content movement process ST7.

[Pointer moving process ST6]
FIG. 18 is a flowchart showing the process of the pointer movement process ST6.
As described above, the pointer moving time process ST6 is a screen corresponding to the image forming area A when the moved pointer P passes through the buffer area BA of the image forming area A set as the target area a predetermined number of times. This is a process for canceling the standby state of S.
In this pointer movement process ST6, as shown in FIG. 18, first, the movement locus acquisition unit 51616 of the object movement time cancellation unit 5161 acquires the movement locus of the pointer P (step ST61).
Next, the movement range determination unit 51617 determines whether or not the pointer P has entered the image forming area A that is the target area set in step ST52, based on the acquired movement locus of the pointer P. (Step ST62). If the movement range determination unit 51617 determines that the pointer P has not entered the image forming area A, the object movement release unit 5161 ends the pointer movement processing ST6.

  On the other hand, when the movement range determination unit 51617 determines that the pointer P has entered the image forming area A that is the target area, the movement locus determination unit 51618 sets the pointer P to the image forming area A. It is determined whether or not the buffer area BA has been passed (step ST63). If the movement locus determination unit 51618 determines that the pointer P does not pass through the buffer area BA, the object movement release unit 5161 corresponds to the image formation area A set as the target area. Without releasing the standby state of the screen S, the pointer moving process ST6 is terminated.

  On the other hand, when the movement trajectory determination unit 51618 determines that the pointer P has passed the buffer area BA, the number determination unit 51619 determines whether the pointer P has passed the buffer area BA a predetermined number of times. (Step ST64). Here, when the number determination unit 51619 determines that the pointer P has not passed the buffer area BA a predetermined number of times, the object movement time cancellation unit 5161 is set to the target area as in the above case. Without releasing the standby state of the screen S corresponding to the image forming area A, the pointer movement processing ST6 is ended.

If the number determination unit 51619 determines that the pointer P has passed the buffer area BA a predetermined number of times, the standby state set in the screen S corresponding to the image forming area A having the buffer area BA is released. (Step ST65). Thereby, the image information related to the partial image to be displayed on the screen S is output to the projector 8 by the image output unit 52, and the partial image is displayed on the screen SC by the projector 8.
Thereafter, the timer reset unit 514 resets the timer related to the image forming area A, which is included in the timer unit 5154 of the standby state setting unit 515, in the standby state setting process ST2 described above (step ST66).
Thus, the pointer movement process ST6 is completed, and the object movement release unit 5161 proceeds to step ST57 of the state monitoring process ST5.

[Content move processing ST7]
FIG. 19 is a flowchart showing the process of the content movement process ST7.
When the content area CA that is activated by being selected by the pointer P or the like has entered the image forming area A that is the target area, as described above, the content moving process ST7 is performed. This is a process for canceling the standby state set in the screen S corresponding to.
In the content movement processing ST7, as shown in FIG. 19, first, the movement trajectory acquisition unit 51616 acquires the movement trajectory of the moved active content area CA (step ST71). Thereafter, based on the acquired movement trajectory of the content area CA, the movement range determination unit 51617 has entered at least a part of the content area CA into the image forming area A set as the target area in step ST52. (Step ST72). If the movement range determination unit 51617 determines that the content area CA has not entered the image forming area A, the object movement release unit 5161 ends the content movement process ST7.

On the other hand, when the movement range determination unit 51617 determines that at least a part of the content area CA has entered the image forming area A that is the target area, the state changing unit 5161A corresponds to the image forming area A. The standby state set for the screen S to be released is released (step ST73). Thereafter, the timer reset unit 514 resets the timer related to the image forming area A, which is included in the timer unit 5154 of the standby state setting unit 515 (step ST74).
As described above, the object movement release unit 5161 ends the content movement process ST7 and proceeds to step ST57 of the state monitoring process ST5.

Returning to FIG. 17, in step ST57 of the state monitoring process ST5, the release determination unit 5161B of the object movement time release unit 5161 has been set as the target area by executing the pointer movement time process ST6 and the content movement time process ST7. It is determined whether or not the standby state of the screen S corresponding to the image forming area A has been released (step ST57).
If the release determination unit 5161B determines that the standby state of the screen S has been released, the process returns to step ST51 in order to acquire the position of the object on the memory 53 and set the target area again. .

On the other hand, if the release determination unit 5161B determines that the standby state of the screen S has not been released, the object position acquisition unit 511 acquires the position of the object on the memory 53 (step ST58). Then, the object moving release unit 5161 returns to Step ST53.
This is because the pointer P and the active content area CA are not moved from the image forming area A where the pointer P and the content area CA are located, and the image forming area A where the pointer P is the target area. This is because there is no need to change the target area when it is within the set buffer area BA. In particular, when the pointer P is located in the buffer area BA and the image forming area A of the target area is changed, the screen corresponding to the image forming area A where the pointer P is located is recognized as an active screen, This is to prevent the standby state of the screen S from being released.

According to MDS1 of this embodiment demonstrated above, there can exist the following effects.
That is, in the buffer area setting step ST54, the buffer area setting unit 51613 is adjacent to the screen S where the pointer P is located (the screen S on which the partial image including the pointer P is displayed) and is in the standby state setting unit 515. In the image forming area A (at least one of the image forming areas A1 to A3) of the memory 53 corresponding to the screen S (at least one of the screens S1 to S3) set to the standby state in the standby state setting process ST2. A buffer area BA is set in an area adjacent to the screen S where the pointer P is located. Then, based on the movement trajectory of the pointer P moved by the pointer movement unit 5121 of the object movement unit 512 in accordance with the operation of the mouse 91 and the keyboard 92, the movement range determination unit 51617 and the movement locus determination unit 51618 cause the pointer to When it is determined that P has entered the buffer area BA and has passed through the buffer area BA, in the number determination step ST63, the number determination unit 51619 determines that the pointer P sets the buffer area BA in advance. It is determined whether the number of times has passed. At this time, if the number determination unit 51619 determines that the pointer P has passed the buffer area BA a predetermined number of times, in the release step ST65, the state change unit 5161A sets the image formation area in which the buffer area BA is set. The standby state of the screen S corresponding to A is canceled.

  According to this, when the pointer P moves from the screen S where the pointer P is located to another screen S that is adjacent to the screen S and set to the standby state, When the buffer area BA set in the image forming area A corresponding to the screen S is passed a predetermined number of times, the standby state of the other screen S is released. For this reason, when the user slightly moves the mouse 91 or the like as the operation device and operates the pointer P, the standby state set on the screen S to which the pointer P is moved is not released. Accordingly, when the standby state of the screen S is canceled by operating the pointer P, the pointer P is operated so as to pass through the buffer area BA of the image forming area A corresponding to the screen S set in the standby state a predetermined number of times. When such an operation is not performed, the standby state of the screen S can be maintained. Accordingly, it is possible to prevent the standby state of the screen S from being released by an operation of the mouse 91 or the like that is not intended by the user, and thus, power saving of the entire MDS 1 can be realized with a simple configuration.

  Further, the above-described pointer movement processing ST6 is executed when the pointer P as the first object moves. That is, unlike the content area CA, when the pointer P that moves frequently on the display image T2 and does not have a display area as large as the content area CA moves, the pointer P sets the buffer area BA in advance. When the number of passes has passed, the standby state of the screen S corresponding to the image forming area A in which the buffer area BA is set is released. According to this, even when the user has moved the pointer P unintentionally, the standby state of the screen S as the movement destination can be reliably maintained. Therefore, it is possible to eliminate the trouble that the standby state is canceled by the user's unexpected operation and the partial image is displayed on the screen S.

In addition, when the content area CA as the second object is moved by the content moving unit 5122 according to the operation of the mouse 91 and the keyboard 92, the movement locus of the content area CA acquired by the movement locus acquisition unit 51616 is displayed. Based on the movement range determination step ST72 of the content movement process ST7, a part of the content area CA enters the image forming area A corresponding to the screen S set in the standby state by the movement range determination unit 51617. It is determined whether or not. If the movement range determination unit 51617 determines that the content area CA has entered the image forming area A, the state changing unit 5161A adds the content area CA to the image forming area A in the second release step ST73. The standby state of the corresponding screen S is released.
According to this, when the content area CA having a predetermined display area moves into the screen S set in the standby state, the standby state of the screen S is released and the content area CA is displayed. Therefore, it is possible to prevent a part of the content area CA that is highly required to be displayed from being displayed. Therefore, the moved content area CA can be reliably displayed.

Further, when the active content area CA is switched by the user's operation on the keyboard 92, the position of the switched content area CA is acquired by the content position acquisition unit 5112. If the screen S corresponding to the image forming area A in which the content area CA is located is set in the standby state by the target area cancellation unit 51624 in the cancellation step ST45, the standby state of the screen S is Canceled.
According to this, when a plurality of content areas CA are located on the display image T2, the desired content area CA can be easily switched and the content area CA can be reliably displayed. Therefore, the selected and activated content area CA can be reliably displayed.
