Description

  In the present invention, two or more monitors (displays) are virtually connected to each other, and pointers for designating positions on the screen in response to an operation of a pointing device or the like can be moved between the screens. It relates to the technology to display.

  When interpreting a medical image acquired with various modalities such as CT (Computed Tomography), MRI (Magnetic Resonance Imaging), or an ultrasonic diagnostic apparatus, the medical image or its medical image is observed. In some cases, a plurality of pieces of information such as a radiogram interpretation report for inputting a message are displayed simultaneously. In such a case, since a large display area is required, a “multi-monitor (multi-display)” in which a plurality of monitors are connected to one computer and displayed as if it were one large monitor. There is a case where a function called is used. Here, two monitors (hereinafter, one is called “primary monitor” and the other is called “secondary monitor”) are connected to one computer, and the right side of the primary monitor screen and the left side of the secondary monitor are connected. An example in which they are virtually connected so as to be continuous will be described.

JP 2006-59251 A

  In such a multi-monitor function, the size of the screen is determined based on the resolution set for each monitor, the positional relationship of the screen of each monitor is specified, and the screens are connected.

  However, the positional relationship between the screens set based on the resolution does not necessarily match the apparent positional relationship (in the physical space) when each monitor is arranged. Further, the number of pixels and the pixel pitch of each monitor are not necessarily the same. Therefore, the distance on each screen based on the resolution does not necessarily match the apparent distance (in physical space) on each monitor.

  For this reason, for example, when two monitors are arranged side by side and the pointer is moved from one screen to the other with a pointing device such as a mouse, the screen before moving and the screen after moving The position of the pointer in the vertical axis may not match. That is, when the pointer is moved along the horizontal direction, the pointer does not move continuously before and after the movement between the screens, and the movement of the pointer does not become intuitive (does not match the user's vision). There is.

  An object of the embodiment of the present invention is to provide a display device that can be operated intuitively even when screens of a plurality of monitors having different numbers of pixels and pixel pitches are virtually connected.

The pointer control unit displays the pointer on one of the first screen and the second screen, and when the pointer reaches one end along the second axis of the one screen, the pointer control unit displays the pointer on the other screen. Move. The reference setting unit determines the position in the first axis direction of the region along the first axis direction shared between the first screen and the second screen for each of the first screen and the second screen. The reference position. The information generation unit receives a designation of the same position between the first screen and the second screen, which is different from the reference position in the region, for each of the first screen and the second screen. The number of pixels a between the designated position and the reference position on the screen of FIG. 5 and the number of pixels b between the designated position and the reference position on the second screen are obtained. The pointer control unit obtains a position along the direction of the first axis based on the ratio b / a of the number of pixels a and b when the pointer is moved from the first screen to the second screen. When the pointer is moved from the screen 2 to the first screen, the position along the direction of the first axis is obtained based on the ratio a / b of the number of pixels a and b, and the pointer is moved to the obtained position.

  First, the configuration of the display device according to the present embodiment will be described with reference to FIG. As shown in FIG. 1, the display device according to the present embodiment includes a U / I 10, a screen information setting unit 21, a screen information storage unit 22, a position designation marker control unit 23, and an inter-screen movement information generation unit 24. And an inter-screen movement information storage unit 25, an operation content analysis unit 31, a pointer control unit 32, and a pointer display update unit 33. The U / I 10 includes an operation unit 101 and display units 102A and 102B (that is, a plurality of monitors). The display device according to the present embodiment provides a mode for performing “position alignment between screens” as preparation before performing a screen operation, and operates a pointer C0 displayed on the screen to display desired information on the screen. It operates in a mode for performing a display operation, that is, a “screen operation”. In the following, description will be made focusing on the configuration that operates in each mode of “alignment between screens” and “screen operation”.

(Alignment between screens)
The screen information setting unit 21 is configured to set the resolution of each screen displayed on the display units 102A and 102B and the positional relationship between the screens. The screen information setting unit 21 sets the screen resolution (in this case, the number of pixels constituting the screen) set in advance for each of the display units 102A and 102B from the U / I 10 (or the display units 102A and 102B). And information indicating the positional relationship between these screens.

  For example, FIG. 2A is a diagram schematically illustrating the resolution of each screen and the positional relationship between the screens. In FIG. 2A, Ma shows the screen of the display unit 102A, and this screen has a width of 750 pixels in the vertical direction and 1000 pixels in the horizontal direction. Mb indicates the screen of the display unit 102B, and this screen has a width of 1375 pixels in the vertical direction and 1000 pixels in the horizontal direction. In the example shown in FIG. 2A, the upper right side of the screen Ma and the lower left side of the screen Mb are arranged to be connected. Hereinafter, the area where the screens Ma and Mb are connected may be referred to as an area Y0. The screen Ma corresponds to the “first screen”, and the screen Mb corresponds to the “second screen”.

  The screen information setting unit 21 sets one of the display units 102A and 102B determined in advance as a primary monitor. In the following description, it is assumed that the display unit 102A (that is, the screen Ma side) is set as a primary monitor, and the display unit 102B (that is, the screen Mb side) is set as a secondary monitor.

The screen information setting unit 21 uses a predetermined position on the screen Ma corresponding to the display unit 102A set in advance as a primary monitor as a reference (origin) of a common coordinate system in the screen Ma and the screen Mb. The position (coordinate determined by the pixel on the screen Ma) and the position of another screen, that is, the screen Mb (coordinate determined by the pixel on the screen Mb) are specified. For example, in the example of FIG. 2A, the position of each screen is specified using the upper left point of the screen Ma, which is the primary monitor, as a reference (ie, origin (0, 0)), the horizontal direction is the x axis, and the vertical direction is the y axis. doing. In this case, the coordinates of each point on the screen Ma are (0, 750) for the lower left point, (1000, 750) for the lower right point, and (1000, 0) for the upper right point. The coordinates of each point on the screen Mb are (1000, 625) for the upper left point, (1000, 625) for the lower left point, (2000, 625) for the lower right point, and (2000, 625) for the upper right point. −625). As shown in FIG. 2A, when the screens Ma and Mb are arranged side by side in the horizontal direction, the y axis corresponds to the “first axis” and the x axis corresponds to the “second axis”. . The origin in the y-axis direction (y = 0) is also the origin on the screen Ma and the screen Mb.
Thus, in order to arrange as shown in FIG. 2A, the upper side of the screen Ma as the primary monitor is set to the origin of y = 0, and in the above example, the screen Mb as the second monitor is located at the position of y = 0. Adjustment is necessary to align the position of the midpoint pixel along the y-axis. In addition, this requires adjustment of the position in real space (so-called visual dimension of the screen) which will be described later. These can be adjusted even in a general computer. If the aligned position is shifted, adjustment is required in the same way. In the following description, this adjustment is described as being made.

  Next, the screen information setting unit 21 specifies a predetermined position in the region Y0 where these screens are joined as the reference position P0 based on the information indicating the position between the specified screens Ma and Mb. For example, in the example shown in FIG. 2C, of the end portions along the y-axis direction of the region Y0, the end portion closer to the x-axis (the point in the region Y0 that first appears along the increasing direction of the y-axis) Is the reference position P0 (that is, in this example, the origin in the y-axis direction (y = 0) is the reference position P0). In the present embodiment, the screen information setting unit 21 that specifies the reference position P0 corresponds to a “reference setting unit”.

  The screen information setting unit 21 includes information indicating the resolution of each screen, information indicating the positional relationship between the screens (that is, the coordinates of the screens Ma and Mb), and position information indicating the specified reference position P0. The screen information is stored in the screen information storage unit 22 as screen information. The screen information storage unit 22 is a storage area for storing screen information.

  It should be noted that the screen resolution of each of the display units 102A and 102B and information indicating the positional relationship between these screens may be set by the operator via the operation unit 101. In this case, the screen information setting unit 21 first receives from the U / I 10 (or the display units 102A and 102B) information indicating the resolution ranges that can be set for the display units 102A and 102B. Based on this information, the screen information setting unit 21 generates an operation screen for designating the resolution of each screen and the positional relationship between these screens, and this operation screen is displayed on at least one of the display units 102A and 102B. To display. The screen information setting unit 21 receives information indicating the resolution of each screen and information indicating the positional relationship between the screens designated on the operation screen via the operation unit 101. The screen information setting unit 21 may store these pieces of information as screen information in the screen information storage unit 22.

  Note that the respective resolutions between the screens Ma and Mb do not necessarily match the sizes actually occupied by the display units 102A and 102B (sizes in the real space). This is because the number of pixels and the pixel pitch are different between the display unit 102A and the display unit 102B, and the magnitude relationship based on the resolution does not consider these pieces of information. In addition, the positional relationship between the screens based on the resolution is not always exactly the same as the physical positional relationship in the height direction of the display units 102A and 102B. Thereby, for example, when the pointer C0 is horizontally moved from the screen Ma toward the screen Mb, the height on the screen Mb of the display unit 102B is different from that on the screen Ma of the display unit 102A due to the difference in pixel pitch. The pointer C0 may be displayed at the position of. Therefore, in the display device according to the present embodiment, in response to an operation from the operator via the operation unit 101, information for correcting a shift due to the difference in the number of pixels or the pixel pitch is generated. Hereinafter, the position designation marker control unit 23, the inter-screen movement information generation unit 24, and the inter-screen movement information storage unit 25 related to the generation of this information will be described. Hereinafter, as shown in FIG. 2A, the coordinate space for recognizing the positional relationship of each screen based on only the resolution (not reflecting the size occupying the real space) as shown in FIG. A physical coordinate space that reflects the actual occupied size such as the position in appearance displayed on the screen of a monitor such as the display units 102A and 102B may be referred to as “real space”.

  The position designation marker control unit 23 displays on each of the screen Ma and the screen Mb markers Xa and Xb for designating positions along the end including the region Y0 to which these screens are connected. Specifically, the position designation marker control unit 23 displays the marker Xa on the screen Ma so as to be movable along the right side (y-axis direction) of the screen Ma. Similarly, the position designation marker control unit 23 displays the marker Xb on the screen Mb so as to be movable along the left side (y-axis direction) of the screen Mb.

  Reference is now made to FIG. 2B. FIG. 2B is a diagram for explaining alignment between the screens, and the positional relationship between the display units 102A and 102B and each of these screens (that is, the screens Ma and Mb) in the real space (in other words, visually). Dimensional positional relationship of the screen). As shown in FIG. 2B, the position in the real space is a visual position including a stand that supports each screen. In FIG. 2B, screens Ma ′ and Mb ′ indicate the screens Ma and Mb in the real space. Markers Xa 'and Xb' indicate the markers Xa and Xb on the real space displayed on the screens Ma 'and Mb'. Y0 'represents an area where the screens Ma' and Mb 'are connected in real space.

  The operator operates the respective screens so that the positions of the markers Xa ′ and Xb ′ along the y-axis (that is, in the vertical direction) visually match in real space via the operation unit 101. To do. For example, the position specifying marker control unit 23 displays the pointer C0 on the screens Ma ′ and Mb ′, and drags each of the markers Xa ′ and Xb ′ with the pointer C0 to operate the position of each marker. May be. As another method, each of the markers Xa ′ and Xb ′ may be displayed along the region Y <b> 0 ′ so that the position can be changed. As a result, the same position in the real space in the region Y0 ′ is designated for the screens Ma ′ and Mb ′ by the markers Xa ′ and Xb ′. In response to the operation from the operation unit 101, the position designation marker control unit 23 specifies the positions of the markers Xa 'and Xb' in the logical space, that is, the positions of the markers Xa and Xb.

  Reference is now made to FIG. 2C. FIG. 2C shows a state after the positions of the markers Xa and Xb in the logical space are specified in response to the designation of the positions of the markers Xa ′ and Xb ′ in the real space in the image shown in FIG. 2A. ing. When the positions of the markers Xa ′ and Xb ′ are matched on the screens Ma ′ and Mb ′ in the real space between the display units 102A and 102B having different pixel pitches, the positions of the markers Xa and Xb in the logical space are as follows: A shift occurs as shown in FIG. 2C.

  The position designation marker control unit 23 notifies the inter-screen movement information generation unit 24 of information indicating the positions of the identified markers Xa and Xb.

  The inter-screen movement information generation unit 24 reads the screen information stored in the screen information storage unit 22. When the screen information is read, the inter-screen movement information generation unit 24 reads the position information of the reference position P0 included in the screen information.

  Next, the inter-screen movement information generation unit 24 receives the positions of the markers Xa and Xb from the position designation marker control unit 23 (specifically, the marker Xa operated so as to match in real space as shown in FIG. 2B). Information indicating the position of 'and Xb' in the logical space) is received. Upon receiving these pieces of information, the inter-screen movement information generation unit 24 calculates widths (that is, the number of pixels) W1a and W1b along the region Y0 between the reference position P0 and the markers Xa and Xb. . In the example of FIG. 2C, the region Ya indicates a region along the y-axis direction with the reference position P0 and the marker Xa as ends. The width W1a indicates the width along the y-axis direction of the region Ya. Similarly, a region Yb indicates a region along the y-axis direction with the reference position P0 and the marker Xb as ends. The width W1b indicates the width along the y-axis direction of the region Yb. The width W1a and the width W1b indicate the same width in the real space, and the difference in the interval in the logical space is due to the difference in the pixel pitch between the display units 102A and 102B. For example, when the pixel pitch of the display unit 102B is 1/2 of the pixel pitch of the display unit 102A, the distance (number of pixels) on the screen Mb in the logical space is the same distance in the real space. Is twice the distance (number of pixels) on the screen Ma.

  3A to 3C show one mode of the positional relationship between the screens Ma and Mb on the logical space when the markers Xa ′ and Xb ′ are operated so that the positions of the markers Xa ′ and Xb ′ coincide in the real space. Yes. For example, FIG. 3A shows an example in which the lower right side of the screen Ma and the upper left side of the screen Mb are joined. In the example of FIG. 3A, the coordinates of each point on the screen Ma are (0, 0) for the upper left point, (0, 750) for the lower left point, (1000, 750) for the lower right point, and (1000, 750) for the upper right point. (1000, 0). The coordinates of each point on the screen Mb are (1000, 250) for the upper left point, (1000, 1500) for the lower left point, (2000, 1500) for the lower right point, and (2000, 250) for the upper right point. ) In this case, of the end portions along the y-axis direction of the region Y0 where the screens Ma and Mb are joined, the end portion closer to the x-axis is the position (1000, 250), and this point is the reference position. P0. The inter-screen movement information generation unit 24 calculates the widths W1a and W1b based on the number of pixels of each screen based on the reference position P0. As described above, in this example, the origin in the y-axis direction is set as the reference position P0. Since the origin in the y-axis direction is the origin for both the screen Ma and the screen Mb, the reference position P0 is It is also a point where markers in the real space match. Therefore, in other words, the widths W1a and W1b correspond to the number of pixels of each screen in the width from the position where the positions on the y-axis in real space coincide with each other to the next coincident position.

  FIG. 3B shows an example in which the screens Ma and Mb are arranged so that the left side of the screen Mb includes the right side of the screen Ma. In the example of FIG. 3B, the coordinates of each point on the screen Ma are (0, 0) for the upper left point, (0, 750) for the lower left point, (1000, 750) for the lower right point, and (1000, 750) for the upper right point. (1000, 0). The coordinates of each point on the screen Mb are (1000, -250) for the upper left point, (1000, 1000) for the lower left point, (2000, 1000) for the lower right point, and (2000, 1000) for the upper right point. −250). In this case, of the end portions along the y-axis direction of the region Y0 where the screens Ma and Mb are joined, the end portion closer to the x-axis is the (1000, 0) position, and this point is the reference position. P0. The inter-screen movement information generation unit 24 calculates the widths W1a and W1b based on the reference position P0.

  FIG. 3C shows an example in which the screens Ma and Mb are arranged so that the right side of the screen Ma includes the left side of the screen Mb. In the example of FIG. 3C, the coordinates of the points on the screen Ma are (0, 0) for the upper left point, (0, 1250) for the lower left point, (1000, 1250) for the lower right point, and (1000, 1250) for the upper right point. (1000, 0). The coordinates of each point on the screen Mb are (1000, 250) for the upper left point, (1000, 1000) for the lower left point, (2000, 1000) for the lower right point, and (2000, 250) for the upper right point. ) In this case, of the end portions along the y-axis direction of the region Y0 where the screens Ma and Mb are joined, the end portion closer to the x-axis is the position (1000, 250), and this point is the reference position. P0. The inter-screen movement information generation unit 24 calculates the widths W1a and W1b based on the reference position P0.

  When the widths W1a and W1b are calculated, the inter-screen movement information generation unit 24 calculates coefficients ka and kb by dividing these. The coefficient ka indicates a coefficient when the pointer C0 is moved from the screen Ma toward the screen Mb. The inter-screen movement information generation unit 24 calculates the coefficient ka based on the calculation formula ka = W1b / W1a. Similarly, the coefficient kb indicates a coefficient when the pointer C0 is moved from the screen Mb toward the screen Ma. The inter-screen movement information generation unit 24 calculates the coefficient kb (= 1 / ka) based on the calculation formula kb = W1a / W1b.

  The inter-screen movement information generating unit 24 generates inter-screen movement information D10 based on the calculated coefficients ka and kb and screen information indicating the positional relationship between the screens Ma and Mb. For example, FIG. 4 shows an example of the data structure of the inter-screen movement information D10. Of the data shown in FIG. 4, each of D11, D12, and D13 is information set by the information setting unit 21 as described above. In FIG. 4, D11 indicates an identifier for identifying the screens Ma and Mb. D12 indicates the priority set between the screens Ma and Mb. Here, the primary screen is given priority as the reference (origin) of the coordinate system in which the two screens are common. In the example of FIG. 4, the screen Ma is set to primary. D13 is position information indicating the positions of the screens Ma and Mb. In the example of FIG. 4, the position of each screen is indicated by an upper left coordinate D131, an upper right coordinate D132, a lower right coordinate D133, and a lower left coordinate D134. The position information D13 is an example, and the data structure is not limited as long as the positions of the screens Ma and Mb can be specified. D14 indicates a coefficient calculated for each of the screens Ma and Mb. In the example of FIG. 4, the coefficient ka corresponds to the screen Ma, and the coefficient kb corresponds to the screen Mb.

  The inter-screen movement information generation unit 24 stores the generated inter-screen movement information D10 in the inter-screen movement information storage unit 25. The inter-screen movement information storage unit 25 is a storage unit for storing the inter-screen movement information D10. When the pointer C0 is moved between the screens Ma and Mb during the screen operation, the display device according to the present embodiment specifies the position of the pointer C0 after the movement based on the inter-screen movement information D10. Hereinafter, operations related to the screen operation will be described.

(Screen operation)
When the operator operates the pointer C0 via the operation unit 101, the operation content, that is, information indicating the movement amount and direction of the operation unit 101 (for example, a mouse) is transmitted from the operation unit 101 to the operation content analysis unit 31. Be notified.

  When receiving the information indicating the operation content from the operation unit 101, the operation content analysis unit 31 calculates the movement amount and movement direction of the pointer C0 as operation information based on this information. The operation content analysis unit 31 outputs the calculated operation information to the pointer control unit 32.

  The pointer control unit 32 is a control unit for managing and controlling the position of the pointer C0. When the display device is activated, the pointer control unit 32 reads the inter-screen movement information D10 from the inter-screen movement information storage unit 25, and the positional relationship between the screens Ma and Mb based on the screen information included in the inter-screen movement information D10. Is identified. The pointer control unit 32 may read this screen information from the screen information storage unit 22 and specify the positional relationship between the screens Ma and Mb.

  In addition, the pointer control unit 32 specifies the position (initial position) of the pointer C0 based on the notified positional relationship between the screens Ma and Mb. Based on the information indicating the specified position, the pointer display update unit 33 described later causes the pointer C0 to be displayed at any one of the screens Mb and Mb (that is, the initial position). The position of the pointer C0 is updated by the pointer control unit 32 when an operation through the operation unit 101 is received. The operation of each unit when receiving the operation of the pointer C0 will be described below.

  The pointer control unit 32 specifies and manages the position of the pointer C0 by the number of pixels on the coordinates determined by the inter-screen movement information D10. The position (coordinates) in the y-axis direction at that time is the screen Ma. Is specified by the number of pixels of the pixel pitch of the screen Ma from the origin (0,0), and when it is in the screen Mb, it is specified by the number of pixels of the pixel pitch of the screen Mb from the origin (0,0). To do. When the pointer C0 moves between the screens Ma and Mb, the pointer control unit 32 uses the coefficients ka and kb indicating the relationship between the screens Ma and Mb in the inter-screen movement information D10 for the position (coordinates) in the y-axis direction. Adjust its position.

  When the pointer C0 is operated via the operation unit 101, the pointer control unit 32 receives operation information of the pointer C0 from the operation content analysis unit 31. The pointer controller 32 specifies on which screen of the screens Ma and Mb the pointer C0 is based on the current position information of the pointer C0. Here, the description will be made assuming that the pointer C0 exists on the screen Ma.

  While monitoring the position of the pointer C0, the pointer control unit 32 receives the operation content for the pointer C0 as operation information at every predetermined timing, and updates the position of the pointer C0 based on this operation information. Specifically, when receiving the operation information, the pointer control unit 32 compares this operation information with the current position information of the pointer C0, and specifies the position after the pointer C0 is moved.

  When the position after the movement of the pointer C0 is specified based on the operation information, the pointer control unit 32 determines whether or not the pointer C0 has reached one end joined with the other screen. For example, when the pointer C0 exists on the screen Ma, the pointer control unit 32 determines whether or not the pointer C0 has reached the right side of the screen Ma. Similarly, when the pointer C0 exists on the screen Mb, the pointer control unit 32 may determine whether or not the pointer C0 has reached the left side of the screen Mb.

  When the pointer C0 has not reached one end joined with the other screen, the pointer control unit 32 outputs information indicating the position after the movement of the specified pointer C0 to the pointer display update unit 33.

  When the pointer C0 reaches one end joined to the other screen, that is, the right side of the screen Ma, the pointer control unit 32 performs the coefficient ka associated with the screen Ma (that is, the screen Ma to the screen Mb). The coefficient ka) when moving toward the movement is extracted from the inter-screen movement information D10. The pointer control unit 32 multiplies the extracted ka by the coordinate in the direction (that is, the y-axis direction) along the region Y0 where the screens Ma and Mb are joined among the coordinates of the pointer C0 after movement. Correct with. The operation at this time will be specifically described below with reference to FIG. 5A. FIG. 5A is a diagram for explaining a method of adjusting the position of the pointer C0 when moving between screens, and shows a case where the pointer C0 moves from the screen Ma toward the screen Mb.

  In the example shown in FIG. 5A, the pointer C0 is moved toward the screen Mb from the position P1a that is separated from the x axis (y = 0) by the width W1 (the number of pixels in the screen Ma) on the screen Ma in the y axis direction. Shows the case. At this time, the pointer control unit 32 extracts the coefficient ka for the width W1 that is the distance along the y-axis direction from the x-axis to the position P1a, that is, the width W1 that is the y-axis direction component of the position P1a. Multiply The pointer control unit 32 uses the width W1 × ka (the number of pixels in the screen Mb) calculated by this calculation as the position along the y-axis direction of the pointer C0 after movement (that is, the y-axis direction component), and the pointer C0. Find the position of.

  When moving from the screen Mb toward the screen Ma, the pointer control unit 32 shifts the coefficient kb associated with the screen Mb from the inter-screen movement information D10 (that is, from the screen Mb to the screen Ma). The coefficient kb) in the case of moving toward is extracted, and the position of the pointer C0 after the movement may be obtained based on the coefficient kb. For example, FIG. 5B shows a case where the pointer C0 has moved from the screen Mb toward the screen Ma.

  In the example shown in FIG. 5B, the pointer C0 is moved toward the screen Ma from the position P2a that is separated from the x axis (y = 0) by the width W2 (the number of pixels in the screen Mb) in the y axis direction on the screen Mb. Shows the case. At this time, the pointer control unit 32 extracts the coefficient kb with respect to the width W2 that is the distance along the y-axis direction from the x-axis to the position P2a, that is, the width W2 that is the y-axis direction component of the position P2a. Multiply The pointer control unit 32 uses the width W2 × kb (the number of pixels in the screen Ma) calculated by this calculation as the position along the y-axis direction of the pointer C0 after movement (that is, the y-axis direction component). Find the position of.

  When the position of the pointer C0 after the movement is obtained, the pointer control unit 32 indicates the information indicating the obtained position and the information indicating the position of the destination screen (that is, the position of the screen Mb when moving from the screen Ma). Information) and determine whether or not the position obtained by the pointer C0 is in the screen after movement (in the screen Mb). When the pointer C0 is in the screen after movement, the pointer control unit 32 outputs information indicating the corrected position of the pointer C0 to the pointer display update unit 33.

  If the position obtained by the pointer C0 is not in the screen after movement, the pointer control unit 32 performs correction so that the pointer C0 moves to a predetermined position in the screen after movement. A specific example of this operation will be described separately for pattern 1 to pattern 3 with reference to FIGS. 6A to 6C.

(Pattern 1)
First, the operation according to the pattern 1 will be described with reference to FIG. 6A. FIG. 6A is a diagram for describing an aspect of adjustment of the pointer position when moving between screens. FIG. 6A shows a case where the pointer C0 obtained by the coefficient Kb as described above is not located in the screen Mb when the pointer C0 is moved from the position indicated by P3b toward the screen Ma from the screen Mb. In this case, the pointer control unit 32, for example, of the end portions (that is, the upper side and the lower side) along the y-axis direction of the screen Ma after movement, the end portion closer to the position of the pointer C0 before movement. The position of the pointer C0 is corrected so as to move to a position on X0. In particular, in the example illustrated in FIG. 6A, the pointer control unit 32 sets a position P10 in contact with the area Y0 where the screens Ma and Mb are joined among the positions on the end X0 as the position P3a of the pointer C0 after movement. to correct.

(Pattern 2)
Next, the operation according to the pattern 2 will be described with reference to FIG. 6B. FIG. 6B shows an aspect different from the example shown in FIG. 6A. In the example shown in FIG. 6B, an example in which the position of the pointer C0 after movement is specified according to the distance between the position of the pointer C0 before movement and the area Y0 where the screens Ma and Mb are joined is shown.

  Specifically, the pointer control unit 32 first sets the distance from the position P10 serving as the base point to the position of the pointer C0 before the movement from the position P10 in contact with the region Y0 among the positions on the end X0. calculate. For example, as illustrated in FIG. 6B, when the position of the pointer C0 before the movement is a position P41b on the screen Mb, the pointer control unit 32 determines the distance W4b between the position P41b and the base position P10. Is calculated.

  When the distance W4b is calculated, the pointer control unit 32 calculates the distance W4a by multiplying the distance W4b by a predetermined ratio. For this ratio, for example, a coefficient kb when moved toward the movement from the screen Mb to the screen Ma may be used. Alternatively, W4a = W4b may be set.

  When the distance W4a is calculated, the pointer control unit 32 corrects a position that is a distance W4a away from the base position P10 on the end X0 as the position P41a of the pointer C0 after movement. That is, when the position of the pointer C0 before movement is a position P42b that is further away from the position P41b along the y-axis direction from the position P10, the pointer control unit 32 moves from the position P10 along the x-axis direction to the position P41a. It is corrected so that the pointer C0 moves to a position P42a further away.

(Pattern 3)
Next, the operation according to the pattern 3 will be described with reference to FIG. 6C. FIG. 6C shows an aspect different from the example shown in FIGS. 6A and 6B. In the example shown in FIG. 6C, the movement is performed according to the distance between the position of the pointer C0 before the movement and the area Y0 where the screens Ma and Mb are joined and the movement direction (entrance angle) of the pointer C0 before the movement. An example of specifying the position of the subsequent pointer C0 is shown.

  Specifically, the pointer control unit 32 first sets the distance from the position P10 serving as the base point to the position of the pointer C0 before the movement from the position P10 in contact with the region Y0 among the positions on the end X0. calculate. For example, as illustrated in FIG. 6B, when the position of the pointer C0 before the movement is a position P41b on the screen Mb, the pointer control unit 32 determines the distance W5b between the position P41b and the base position P10. Is calculated.

  Further, when the pointer C0 enters the position P50b on the screen Mb, the pointer control unit 32 specifies the moving direction of the pointer C0 based on the position information of the pointer C0 immediately before and the position information of the position P50b. As a specific example, the pointer control unit 32 may hold the position information of the pointer C0 for a predetermined time immediately before (for example, 100 msec) and calculate the moving direction of the pointer C0 based on the information. In the example of FIG. 6C, this movement direction is indicated by an angle formed with the end X0. For example, when the pointer C0 enters the position P50b along the direction P51b, the pointer control unit 32 specifies the angle θ1 formed by the movement direction P51b and the end X0 as information indicating the movement direction of the pointer C0. . Similarly, when the pointer C0 enters the position P50b along the direction P52b, the pointer control unit 32 specifies the angle θ2 formed by the movement direction P52b and the end X0 as information indicating the movement direction of the pointer C0. To do. As long as the moving direction of the pointer C0 can be specified, the information indicating the moving direction is not limited to the information indicating the angle. For example, information indicating the moving direction may be specified as a vector indicated by an x-axis direction component and a y-axis direction component.

  When the distance W5b and the moving direction of the pointer C0 (that is, the angle θ1 or θ2) are specified, the pointer control unit 32 specifies the position on the end X0 based on these pieces of information. As a specific example, the pointer control unit 32 specifies a position where a line extending the moving direction of the pointer C0 that has entered the position P50b intersects with the end X0 based on these pieces of information.

  For example, assume that the pointer C0 enters the position P50b in the movement direction P51b. In this case, the pointer control unit 32 calculates the distance W51a = W5b · tan θ1 from the position P10 serving as the base point on the end X0 based on the distance W5b and the angle θ1. When the distance W51a is calculated, the pointer control unit 32 corrects a position separated by the distance W51a from the base position P10 on the end X0 as the position P51a of the pointer C0 after movement.

  Similarly, assume that the pointer C0 enters the position P50b in the movement direction P52b. In this case, the pointer control unit 32 calculates the distance W52a = W5b · tan θ1 from the position P10 serving as the base point on the end X0 based on the distance W5b and the angle θ2. When the distance W52a is calculated, the pointer control unit 32 corrects a position that is a distance W52a away from the base position P10 on the end X0 as the position P52a of the pointer C0 after movement.

  When the pointer C0 reaches one end joined to the other screen, the pointer control unit 32 does not immediately move the pointer C0 to the other screen, but reaches a predetermined time (for example, several hundreds). [Msec]), the pointer C0 may be moved. By operating in this way, when the operator moves the pointer C0 unintentionally due to an operation mistake, it is possible to reduce the case where the pointer C0 moves against the operator's intention.

  Further, the pointer control unit 32 is operated so as to adjust the moving speed of the pointer C0 in the logical space (the ratio of the moving amount of the pointer C0 to the operating amount of the operating unit 101 such as a mouse) by the coefficients ka and kb. May be. As described above, when the pixel pitch is different, the distance occupied in the real space is different from the number of pixels in the logical space. Therefore, even when the operation amount for the pointer C0 is the same on each screen, the movement amount (movement distance) of the pointer C0 in the real space is shorter on the screen with the finer pixel pitch than on the other screen (that is, the screen). The moving speed of the pointer C0 is slow). Therefore, when the movement amount of the pointer C0 in the logical space with respect to the operation amount (that is, the movement speed of the pointer C0) is adjusted by the coefficients ka and kb, In addition, it is possible to display the moving speed of the apparent pointer C0 constant.

  As described above, when the pointer C0 moves between the screens, the position of the pointer C0 is corrected based on the coefficients ka and kb, so that even when the pixel pitch is different between the display units 102A and 102B, Before and after the movement, the position of the pointer C0 does not change and operates continuously. Therefore, the operation of the pointer C0 matches the visual sense of the operator, and an intuitive operation is possible.

  Further, in the conventional display device, it is possible to move between the screens Ma and Mb only from the region Y0 where the screens Ma and Mb are virtually joined. Therefore, even if an attempt is made to move the pointer C0 to the other screen through a place other than the area Y0, the position of the pointer C0 is not moved and remains on the one screen. Therefore, when the operator moves the pointer C0 from one screen to the other screen, the operator needs to move the pointer C0 to the position of the area Y0. As a result, the operation became intermittent and the usability was poor. However, by controlling the position of the pointer C0 as described above, it is possible to move the pointer C0 to the other screen from a place other than the region Y0 that joins the screens Ma and Mb. Therefore, the operation becomes continuous, and the operator can perform a more intuitive operation.

  When the pointer control unit 32 specifies the position of the pointer C0 after movement, the pointer control unit 32 outputs position information indicating the position to the pointer display update unit 33. When the pointer display update unit 33 receives the position information of the pointer C0, the display of the display units 102A and 102B is displayed so that the pointer C0 is displayed at a position on the screen Ma or Mb indicated by the position information. Update.

  Next, the operation of the display device according to the present embodiment will be described with reference to FIGS. 7A and 7B.

  First, the operation in the mode for performing “position alignment between screens” will be described with reference to FIG. 7A. FIG. 7A is a flowchart showing the operation of the display device according to the present embodiment in a mode for performing “position alignment between screens”.

(Step S11)
The screen information setting unit 21 is configured to set the resolution of each screen displayed on the display units 102A and 102B and the positional relationship between the screens. The screen information setting unit 21 indicates information indicating the screen resolution set in advance for each of the display units 102A and 102B from the U / I 10 (or the display units 102A and 102B) and the positional relationship between these screens. Receive information.

  The screen information setting unit 21 sets one of the display units 102 </ b> A and 102 </ b> B as a primary monitor having a high priority. In the following description, it is assumed that the display unit 102A (that is, the screen Ma side) is set as a primary monitor, and the display unit 102B (that is, the screen Mb side) is set as a secondary monitor.

  The screen information setting unit 21 specifies the position of the other screen, that is, the screen Mb, that is, the coordinates on the basis of the predetermined position on the screen Ma corresponding to the display unit 102A that is preset as the primary monitor. . For example, in the example of FIG. 2A, the position of each screen is specified with the upper left point of the screen Ma as a reference (that is, the origin (0, 0)) and the horizontal direction as the x axis and the vertical direction as the y axis. In this case, the coordinates of each point on the screen Ma are (0, 750) for the lower left point, (1000, 750) for the lower right point, and (1000, 0) for the upper right point. The coordinates of each point on the screen Mb are (1000, 750) for the upper left point, (1000, 625) for the lower left point, (2000, 625) for the lower right point, and (2000, 625) for the upper right point. -750).

  Next, the screen information setting unit 21 specifies a predetermined position in the region Y0 where these screens are joined as the reference position P0 based on the information indicating the position between the specified screens Ma and Mb. For example, in the example shown in FIG. 2C, of the end portions along the y-axis direction of the region Y0, the end portion closer to the x-axis (the point in the region Y0 that first appears along the increasing direction of the y-axis) Is the reference position P0.

  The screen information setting unit 21 includes information indicating the resolution of each screen (here, the number of pixels), information indicating the positional relationship between the screens (that is, the coordinates of the screens Ma and Mb), and the identified reference position. The position information indicating P0 is stored in the screen information storage unit 22 as screen information.

  It should be noted that the screen resolution of each of the display units 102A and 102B and information indicating the positional relationship between these screens may be set by the operator via the operation unit 101. In this case, the screen information setting unit 21 first receives from the U / I 10 (or the display units 102A and 102B) information indicating the resolution ranges that can be set for the display units 102A and 102B. Based on this information, the screen information setting unit 21 generates an operation screen for designating the resolution of each screen and the positional relationship between these screens, and this operation screen is displayed on at least one of the display units 102A and 102B. To display. The screen information setting unit 21 receives information indicating the resolution of each screen and information indicating the positional relationship between the screens designated on the operation screen via the operation unit 101. The screen information setting unit 21 may store these pieces of information as screen information in the screen information storage unit 22.

(Step S12)
The position designation marker control unit 23 displays on each of the screen Ma and the screen Mb markers Xa and Xb for designating positions along the end including the region Y0 to which these screens are connected. Specifically, the position designation marker control unit 23 displays the marker Xa on the screen Ma so as to be movable along the right side (y-axis direction) of the screen Ma. Similarly, the position designation marker control unit 23 displays the marker Xb on the screen Mb so as to be movable along the left side (y-axis direction) of the screen Mb.

  Reference is now made to FIG. 2B. The operator operates the respective screens so that the positions of the markers Xa ′ and Xb ′ along the y-axis (that is, in the vertical direction) visually match in real space via the operation unit 101. To do. For example, the position specifying marker control unit 23 displays the pointer C0 on the screens Ma ′ and Mb ′, and drags each of the markers Xa ′ and Xb ′ with the pointer C0 to operate the position of each marker. May be. As another method, each of the markers Xa ′ and Xb ′ may be displayed along the region Y <b> 0 ′ so that the position can be changed. As a result, the same position in the real space in the region Y0 ′ is designated for the screens Ma ′ and Mb ′ by the markers Xa ′ and Xb ′. In response to the operation from the operation unit 101, the position designation marker control unit 23 specifies the positions of the markers Xa 'and Xb' in the logical space, that is, the positions of the markers Xa and Xb.

  The position designation marker control unit 23 notifies the inter-screen movement information generation unit 24 of information indicating the positions of the identified markers Xa and Xb.

(Step S13)
The inter-screen movement information generation unit 24 reads the screen information stored in the screen information storage unit 22. When the screen information is read, the inter-screen movement information generation unit 24 reads the position information of the reference position P0 included in the screen information.

(Step S14)
Next, the inter-screen movement information generation unit 24 receives the positions of the markers Xa and Xb from the position designation marker control unit 23 (specifically, the marker Xa operated so as to match in real space as shown in FIG. 2B). Information indicating the positions of “and Xb” is received. Upon receiving these pieces of information, the inter-screen movement information generation unit 24 calculates widths (that is, the number of pixels) W1a and W1b along the region Y0 between the reference position P0 and the markers Xa and Xb. . In the example of FIG. 2C, the region Ya indicates a region along the y-axis direction with the reference position P0 and the marker Xa as ends. The width W1a indicates the width along the y-axis direction of the region Ya. Similarly, a region Yb indicates a region along the y-axis direction with the reference position P0 and the marker Xb as ends. The width W1b indicates the width along the y-axis direction of the region Yb. The width W1a and the width W1b indicate the same width in the real space, and the difference in the interval in the logical space is due to the difference in the pixel pitch between the display units 102A and 102B. For example, when the pixel pitch of the display unit 102B is ½ of the pixel pitch of the display unit 102A, when the same distance is shown in the real space, the distance (number of pixels) on the screen Mb in the logical space. ) Is twice the distance (number of pixels) on the screen Ma.

  When the widths W1a and W1b are calculated, the inter-screen movement information generation unit 24 calculates coefficients ka and kb by dividing these. The coefficient ka indicates a coefficient when the pointer C0 is moved from the screen Ma toward the screen Mb. The inter-screen movement information generation unit 24 calculates the coefficient ka based on the calculation formula ka = W1b / W1a. Similarly, the coefficient kb indicates a coefficient when the pointer C0 is moved from the screen Mb toward the screen Ma. The inter-screen movement information generation unit 24 calculates the coefficient kb (= 1 / ka) based on the calculation formula kb = W1a / W1b.

  The inter-screen movement information generating unit 24 generates inter-screen movement information D10 based on the calculated coefficients ka and kb and screen information indicating the positional relationship between the screens Ma and Mb.

(Step S15)
The inter-screen movement information generation unit 24 stores the generated inter-screen movement information D10 in the inter-screen movement information storage unit 25.

  Next, the operation in the mode for performing the “screen operation” will be described with reference to FIG. 7B. FIG. 7B is a flowchart showing the operation of the display device according to the present embodiment in the mode for performing “screen operation”.

(Step S21)
When the display device is activated, the pointer control unit 32 reads the inter-screen movement information D10 from the inter-screen movement information storage unit 25, and the positional relationship between the screens Ma and Mb based on the screen information included in the inter-screen movement information D10. Is identified. The pointer control unit 32 may read this screen information from the screen information storage unit 22 and specify the positional relationship between the screens Ma and Mb.

  When the operator operates the pointer C0 via the operation unit 101, the operation content, that is, information indicating the movement amount and direction of the operation unit 101 (for example, a mouse) is transmitted from the operation unit 101 to the operation content analysis unit 31. Be notified.

(Step S22)
When receiving the information indicating the operation content from the operation unit 101, the operation content analysis unit 31 calculates the movement amount and movement direction of the pointer C0 as operation information based on this information. The operation content analysis unit 31 outputs the calculated operation information to the pointer control unit 32.

  When the pointer C0 is operated via the operation unit 101, the pointer control unit 32 receives operation information of the pointer C0 from the operation content analysis unit 31. The pointer controller 32 specifies on which screen of the screens Ma and Mb the pointer C0 is based on the current position information of the pointer C0. Here, the description will be made assuming that the pointer C0 exists on the screen Ma.

  While monitoring the position of the pointer C0, the pointer control unit 32 receives the operation content for the pointer C0 as operation information at every predetermined timing, and updates the position of the pointer C0 based on this operation information. Specifically, when receiving the operation information, the pointer control unit 32 compares this operation information with the current position information of the pointer C0, and specifies the position after the pointer C0 is moved.

(Step S23)
When the position after the movement of the pointer C0 is specified based on the operation information, the pointer control unit 32 determines whether or not the pointer C0 has reached one end joined with the other screen. For example, when the pointer C0 exists on the screen Ma, the pointer control unit 32 determines whether or not the pointer C0 has reached the right side of the screen Ma. Similarly, when the pointer C0 exists on the screen Mb, the pointer control unit 32 may determine whether or not the pointer C0 has reached the left side of the screen Mb.

(Step S23, Step S24)
If the pointer C0 has not reached one end joined with the other screen (step S23, N), the pointer control unit 32 updates the pointer display information indicating the position after the movement of the specified pointer C0. It outputs to the part 33 (step S24).

(Step S23, Step S31)
When the pointer C0 reaches one end joined to the other screen, that is, the right side of the screen Ma (step S23, Y), the pointer control unit 32 performs the coefficient ka (that is, the screen) associated with the screen Ma. The coefficient ka) in the case of moving toward the movement from Ma to the screen Mb is extracted from the inter-screen movement information D10 (step S31).

(Step S32)
The pointer control unit 32 multiplies the extracted ka by the coordinate in the direction (that is, the y-axis direction) along the region Y0 where the screens Ma and Mb are joined among the coordinates of the pointer C0 after movement. Correct with. The operation at this time will be specifically described below with reference to FIG. 5A. FIG. 5A is a diagram for explaining a method of adjusting the position of the pointer C0 when moving between screens, and shows a case where the pointer C0 moves from the screen Ma toward the screen Mb.

  In the example shown in FIG. 5A, the pointer C0 is moved toward the screen Mb from the position P1a that is separated from the x axis (y = 0) by the width W1 in the y axis direction on the screen Ma. At this time, the pointer control unit 32 performs a width W1 that is a distance along the y-axis direction from the x-axis (y = 0) to the position P1a, that is, a width W1 that is a y-axis direction component of the position P1a. Multiply the extracted coefficient ka. The pointer control unit 32 obtains the position of the pointer C0 using W1 × ka calculated by this calculation as a position along the y-axis direction of the pointer C0 after movement (that is, the y-axis direction component).

(Step S33, Step S24)
After obtaining the position of the pointer C0 after movement, the pointer control unit 32 information indicating this position and information indicating the position of the screen after movement (that is, information indicating the position of the screen Mb when moving from the screen Ma). To determine whether or not the pointer C0 whose position has been obtained is located within the screen after movement. When the pointer C0 is located in the screen after movement (step S33, N), the pointer control unit 32 outputs information indicating the corrected position of the pointer C0 to the pointer display update unit 33 (step S33). S24).

(Step S33, Step S34)
When the pointer C0 whose position has been obtained is not located in the screen after movement (step S33, Y), the pointer controller 32 causes the pointer C0 to move to a predetermined position in the screen after movement. Make corrections.

  As a specific example, the pointer control unit 32 has an end X0 closer to the position of the pointer C0 before the movement among the ends (that is, the upper side and the lower side) along the y-axis direction of the screen Ma after the movement. The position of the pointer C0 is corrected so as to move to the upper position. In particular, in the example illustrated in FIG. 6A, the pointer control unit 32 sets a position P10 in contact with the area Y0 where the screens Ma and Mb are joined among the positions on the end X0 as the position P3a of the pointer C0 after movement. to correct.

  Further, as shown in FIG. 6B, the pointer control unit 32 determines the position of the pointer C0 after movement according to the distance between the position of the pointer C0 before movement and the area Y0 where the screens Ma and Mb are joined. You may specify. Further, as shown in FIG. 6C, the pointer control unit 32 determines the distance between the position of the pointer C0 before movement and the area Y0 where the screens Ma and Mb are joined, and the movement direction (entry of the pointer C0 before movement). The position of the pointer C0 after movement may be specified according to the angle.

  When the position of the pointer C0 after movement is specified, the pointer control unit 32 outputs position information indicating this position to the pointer display update unit 33 (step S24).

(Step S25)
When the pointer display update unit 33 receives the position information of the pointer C0 from the pointer display update unit 33, the pointer display update unit 33 displays the pointer C0 so that the pointer C0 is displayed at a position on the screen Ma or Mb indicated by the position information. The display of the parts 102A and 102B is updated.

(Step S26)
Until the end of the display device is instructed (step S26, N), as described above, the operation of the pointer C0 is accepted, the position of the pointer C0 after the movement is specified based on the contents of the operation, and the display of the pointer C0 is updated. Repeat the operation. When the display device is instructed to end (step S26, Y), the series of operations described above is ended.

  As described above, the display device according to the present embodiment corrects the position of the pointer C0 based on the coefficients ka and kb as described above when the pointer C0 moves between the screens, thereby displaying the display units 102A and 102B. Even when the pixel pitch is different between the two, the position of the pointer C0 does not change before and after the movement between the screens, and it operates continuously. Therefore, the operation of the pointer C0 matches the visual sense of the operator, and an intuitive operation is possible.

  Further, in the conventional display device, it is possible to move between the screens Ma and Mb only from the region Y0 where the screens Ma and Mb are virtually joined. Therefore, even if an attempt is made to move the pointer C0 to the other screen through a place other than the area Y0, the position of the pointer C0 is not moved and remains on the one screen. Therefore, when the operator moves the pointer C0 from one screen to the other screen, the operator needs to move the pointer C0 to the position of the area Y0. As a result, the operation became intermittent and the usability was poor. However, by controlling the position of the pointer C0 as described above, it is possible to move the pointer C0 to the other screen from a place other than the region Y0 that joins the screens Ma and Mb. Therefore, the operation becomes continuous, and the operator can perform a more intuitive operation.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
