Description

  The present invention relates to an image display / processing terminal, a system, a program, and a storage medium, for example.

  Conventionally, the entire desktop screen of a computer terminal or an entire predetermined window is captured and sent to another terminal, and a transparent whiteboard is displayed on the desktop screen, and the writing information drawn on the desktop is displayed on the other screen. There is a screen sharing system in which the writing information is displayed on the desktop screen sent to the terminal and displayed on the desktop screen sent earlier (see Patent Document 1).

  This screen sharing system is assumed to capture the entire desktop screen or the entire predetermined window and send it to another terminal.

  Furthermore, in the technique of Patent Document 1, the whiteboard is irrelevant to screen capture, and is used only for sharing handwritten data or the like superimposed on the captured screen.

There are one through a server only, one-to-many connection in which one terminal and a plurality of terminals are connected through a server, and a group conversation without using a server. In the example of FIG. 1, a one-to-one information sharing mode is taken as an example, but in addition to this, a one-to-many mode of lecture format or each participant arbitrarily to one or a plurality of other participants Of course, many-to-many aspects such as transmitting information are also within the scope of the present invention.

  In addition, the following description will be made taking an example of a form of peer-to-peer connection (peer to peer) directly connected via a communication cable, but one-to-one, one-to-many, and many-to-many performed via a server. Of course, the embodiments are also within the scope of the present invention. The advantages of performing communication in the form of peer-to-peer are that the server is not burdened and that high-speed communication can be realized by direct connection without using a relay server. Applications suitable for peer-to-peer connections include video applications (such as video chat) that handle large amounts of data and applications that require real-time processing (such as whiteboards). Is mentioned.

  In FIG. 1, terminals 1A and 1B are connected to a network 2 as transmission means via nodes 2a and 2b, respectively, and a bidirectional dialogue between these terminals 1A and 1B is possible.

The terminal 1A that is set to a simple state selectively transmits a part of the display screen of the terminal 1A from the terminal 1A to the terminal 1B.

  FIG. 2 is a block diagram of a configuration of a terminal that can implement the image display / processing technique according to the first embodiment of the present invention. The terminal 1A (1B) includes a display device 200A (200B) such as a monitor, a PC main body 100A (100B) that performs video processing, an external recording device 700A (700B), and a pointing device 400A (400B) such as a mouse. And a keyboard 500A (500B), a microphone 600A (600B), and a speaker 300A (300B). Since the terminal 1B has the same configuration, only the terminal 1A will be described below.

  Note that the embodiment of the present invention or a specific example of the present invention described in the embodiment is realized by the CPU controlling each hardware based on software stored in the PC.

  The PC main body 100A includes a control unit 120 that performs display / processing of image data transmitted from the other party through the network 2, and a storage unit 130 for storing image data to be transmitted and received. In the drawing, D / B), a drawing unit 140 having a VRAM 141 for displaying a predetermined pattern on the display device 200A in accordance with an instruction from the control unit 120, and capturing of positional information from a pointing device 400A such as a mouse A data input / output unit 150 (I / O in the figure) enabling data exchange with the external device 700A, a sound source controller 160 for controlling the speaker 300A from which the other party's voice is output, a camera 800A, Is provided.

  The external recording device 700A includes, for example, a magnetic tape, a CD, an optical disk, a hard disk, a DVD, a flash memory, and the like, and is a computer program that implements the image display / processing technique according to the present invention and transmission data from the other party Etc. are stored.

  The image display / processing technique according to the first embodiment of the present invention is an interactive dialogue executed between the point A where the terminal 1A having the above-described structure is installed and the point B where the terminal 1B is installed. Is particularly effective.

  Reference is made to the flow diagrams with transition screens of FIGS.

  In these figures, the left two columns indicate the operation and screen state of the terminal A, and the right two columns indicate the screen state of the terminal B. Here, the screen state of the terminal B in the right two columns is affected by the operation and the screen state in the terminal A in the left two columns, while the terminal A ( The state in the left two columns) is not affected. However, this is only one example for facilitating the description of the embodiment of the present invention, and the correspondence relationship from terminal A to terminal B as described below is set in the direction from terminal B to terminal A. Of course, interrelated embodiments are also feasible.

  3A, first, an operation is started at the terminal A (3A01) (step S3A001), and as a result, an image is displayed on the screen (step S3A003).

  Next, a capture frame is displayed on terminal A (3A01) (step S3A005). In this state, for example, a screen such as a screen 3A005 is displayed on the terminal A (3A01). In this screen, screen 3A0005a is a capture frame. In this case, the capture frame is in a through display state, and the inside of the frame is apparently transparent, and the lower window image (screen 3A005b) and the desktop screen are displayed. A part of (screen 3A005c) is displayed as it is in the capture frame (3A005a) and can be observed.

  In this state, in the communication destination terminal B (3A03), a capture frame (through state) is displayed at a predetermined position on the screen (step S3A005 'and screen 3A005'). On the screen 3A005 ', the desktop screen (screen 3A005'c) of the terminal B (3A03) is displayed as it is.

  Here, the “predetermined position” can be arbitrarily determined by the operator at the terminal B (3A03) and affects the movement, enlargement, and reduction of the capture frame (3A0005a) at the terminal A (3A01), as will be described later. It is possible to prevent this from happening, or it is possible to accurately reflect the movement, enlargement, and reduction of the capture frame (3A005a) at the terminal A.

  Next, the terminal A (3A01) captures a desired image displayed in the capture frame (step S3A007). Here, “capture” refers to temporarily or regularly storing one or a plurality of window image data (in this case, a part of a window) displayed in a frame surrounded by a capture frame (3A007a). Is to store. The captured image is fixedly displayed in the capture frame (3A007a). Thereafter, the capture frame (3A007a) is not in the through display state regardless of movement, enlargement, or reduction of the capture frame, and the captured image is displayed. Will be inserted.

  In this state, in the terminal B (3A03), the image captured in the capture frame (3A007a) of the terminal A is displayed in the capture frame (3A007'a) at a predetermined position on the screen (step S3A007 ', and , Screen 3A007 ').

  The reference screen (screen 3A007r) is the screen 3A007 in step S3A007, and the capture frame (3A007a) is moved in the upper left direction. As can be seen, in the state where the captured image is displayed, the image displayed in the frame does not change even when the capture frame (3A007a) is moved. Next, referring to FIGS. 3-B and 3-A, in step S3B009, terminal A (3A01) determines whether to capture an image other than the image captured in step S3A007. If YES, step S3A007 is executed again.

  On the other hand, if NO (no image other than the image captured in step S3A007 is captured), the process proceeds to step S3B011.

  In step S3B011, it is determined whether an image below the capture frame is selected by the mouse in a state where the image is captured in the capture frame in step S3A007. If NO, the process returns to step S3B009 again to determine whether to capture another image.

  On the other hand, if YES (the image below the capture frame has been selected with the mouse), in step S3B013, the inside of the capture frame is displayed as a through display. In this case, as shown in the image 3B013, the lower layer image (3B013b) selected by the mouse can be observed through the apparently transparent capture frame (3B013a). That is, the lower layer image is displayed in the capture frame.

  If the screen below the capture frame (3B013a) has been selected, it is highly likely that the operator intends to capture the image next. Accordingly, (i) the image captured in step S3A007 is cleared, (ii) the through display state is set, and (iii) the image below the capture frame (3B013a) is captured again. Instead, the process of (i) and (ii) is automatically performed with the selection of the lower layer screen as a trigger.

  This makes it possible to capture a user-friendly and simple screen.

  On the other hand, in the state of step S3B013, in the terminal B (3A03), the image captured immediately before by the terminal A (3A01) is continuously displayed or repeatedly redisplayed in the capture frame at a predetermined position on the screen. (Step S3B013 ′ and screen 3B013 ′).

  The reason for not reflecting the image of the capture frame (3B013a) of the terminal A (3A01) in the capture frame (3B013′a) in the terminal B (3A03) is that the next captured image in the terminal A (3A01) is fixed Until the terminal A (3A01) faithfully displays an image displayed in the capture frame (3A3B013a) on the terminal A (3A01) in the capture frame (3B013′a) of the terminal B (3A03) This is because it is annoying for the operator of B (3A03).

  The reason why the capture frame (3B013′a) is not set to the through display state in the terminal B (3A03) is that the terminal B (3A03) immediately before the next image is captured in the terminal A (3A01). This is because it is better to display the captured image and use it for the examination at the terminal B (3A03).

  Rather, it is sufficient to display the image in the capture frame (3B013'a) of the terminal B (3A03) after the next captured image is determined in the terminal A (3A01). Of course, the image displayed in the capture frame (3A3B013a) of the terminal A (3A01) may be displayed faithfully in the capture frame (3B013'a) of the terminal B (3A03). What is necessary is just to select previously or suitably so that it may be in any state according to a use.

  Referring to FIG. 3-C, terminal A (3A01) next operates the lower layer image surrounded by the capture frame (3C015a) in the through display state (step S3C015 and screen 3C015). “Operation” includes movement, enlargement, reduction of the image, display of another image, and the like. In short, an image to be captured next is searched, and a portion that is particularly desired to be captured is surrounded by a capture frame (3C015a).

  At this time, the capture frame on the terminal B (3A03) and the display image therein are not changed from the image (3A07a) most recently captured by the terminal A (3A01). The reason is as described above.

  Next, in step S3C017, it is determined whether the capture frame (3C015a) has been selected by the terminal A (3A01). If not selected (NO), the process returns to step S3C015 to operate the lower layer screen.

  If the capture frame is selected (YES), the “other image” (part of the screen 3C021b surrounded by 3C021a) captured in the capture frame, which is different from the previously captured image (3A007a) ) Is captured in the capture frame (3C021a) (step S3C019).

  If YES in step S3C019 (capture another image), the process proceeds to step S3C021, and the lower layer image (part of the screen 3C021b) surrounded by the capture frame is captured in the capture frame (3C021a). The

  On the other hand, if NO in step S019 (no other image is captured), step S0169 is repeated until it is determined that another image is to be captured.

  The reference screen (screen 3C021r) is obtained by moving the capture frame (3C021a) in which the image is captured on the screen 3C021 in the lower right direction. As can be seen, in the state where the captured image is displayed, the image displayed in the frame does not change even when the capture frame (3C021a) is moved.

  In the state of step S3C021, terminal B (3A03) displays the image captured by terminal A (3A01) within the capture frame (3C021'a) of terminal B. Accordingly, it can be confirmed that the terminal B (3A03) has captured an image different from the previous one.

  By the end of the above process, the exemplary steps of the first embodiment are completed (step S3C023).

  These flowcharts show one exemplary flow that can be adopted in the embodiment of the first embodiment of the present invention. In practice, a flow of processing different from this flow is adopted. obtain. This is because the basic feature of the present embodiment is that when the lower layer image of the capture frame is selected by the mouse (“Y” in step S3B009), the capture frame is displayed as a through display (step S3B010). is there.

  Another basic feature of the present embodiment is that the terminal B (3A03) is reflected so as to continue displaying the image (for example, 3A007a) most recently captured by the terminal A (3A01). This is because unnecessary information can be prevented from being sent to the terminal B. Even if the capture frame is moved, enlarged, or reduced at the terminal A, it is preferable that the terminal B maintains the capture frame at a predetermined position and size. This is because it is convenient for examining the image on the terminal B.

  This embodiment is mainly useful when an image that is surrounded by a capture frame and desired to be captured is changed or its position is moved. In other words, it is useful when the lower layer image that can be observed through the capture frame displayed through is freely changed when the image to be captured is not decided.

  In addition, in a state where a predetermined image is not captured in the capture frame (for example, 3B013a), an image captured immediately before the capture frame can be recognized in the capture frame in the through display state, and a lower layer image can also be recognized. It is also convenient to display the image so thinly (not shown), or display the image captured by the terminal B so thinly that the lower layer image can be recognized (not shown). With such a configuration, it is possible to easily compare an image to be captured in the future with an image captured previously or an image captured by a communication partner.

  Furthermore, a configuration may be adopted in which a memo or the like can be written in the capture frame in a state where a predetermined image is captured in the capture frame (for example, 3A007a) (see FIG. 5). With this configuration, in addition to the lower-level image capturing function, a function that enables writing of predetermined information can be provided.

  Reference is made to the flow diagrams with transition screens of FIGS. In these figures, the left two columns indicate the operation and screen state of the terminal A, and the right two columns indicate the screen state of the terminal B. Here, the screen state of the terminal B in the right two columns is affected by the operation and the screen state in the terminal A in the left two columns, while the terminal A ( The state in the left two columns) is not affected. However, this is only one example for facilitating the description of the embodiment of the present invention, and the correspondence relationship from terminal A to terminal B as described below is set in the direction from terminal B to terminal A. Of course, interrelated embodiments are also feasible.

  4A, first, an operation is started at the terminal A (4A01) (step S4A001), and as a result, an image is displayed on the screen (S4A003) (not shown).

  Next, a capture frame is displayed on terminal A (4A01) (step S4A005). In this state, for example, a screen such as the screen 4A005 is displayed on the terminal A (4A01). In this screen, 4A0005a is a capture frame. In this case, the capture frame is in a through display state, and the lower layer window image (screen 4A005b) and a part of the desktop screen (screen 4A005c) are visible as they are. It is displayed in the upper transparent capture frame (4A005a) and can be observed.

  In this state, in the communication destination terminal B (4A03), a capture frame (through display state) is displayed at a predetermined position on the screen (step S4A005 'and screen 4A005'). On the screen 4A005 ', the desktop screen (screen 4A005'c) of the terminal B (4A03) is displayed as it is.

  Here, the “predetermined position” can be arbitrarily determined by the operator at the terminal B (4A03) and affects the movement, enlargement, and reduction of the capture frame (4A0005a) at the terminal A (4A01), as will be described later. It is possible to prevent this from happening, or it is possible to accurately reflect the movement, enlargement, and reduction of the capture frame (4A005a) at the terminal A.

  Next, the terminal A (4A01) captures a desired image displayed in the capture frame (step S4A007). The significance of capture is as described above. In this state, in the terminal B (4A03), the image captured in the capture frame (4A007a) of the terminal A is displayed in the capture frame (4A007'a) at a predetermined position on the screen (step S4A007 ', and , Screen 4A007 ').

  Next, with reference to FIG. 4-B, it is determined whether or not the terminal A (4A01) captures another image different from the image (4A007a) captured in step S4A007 (step S4B009).

  If YES (capture another image), the process returns to step S4A007 again, and the image is captured in the capture frame.

  If NO (other images are not captured), the process proceeds to step S4B011.

  In step S4B011, it is determined whether dragging of the capture frame (4A007a) has started.

  If YES (dragging of capture frame (4A007a) is started), the process proceeds to step S4B013, the capture frame is displayed in a through display (transparent), and the lower layer image (here, window screen 4B013b) is displayed. (Image 4B013a). If the capture frame (4B011a) has been dragged, it is highly likely that the operator intends to capture another portion of the underlying image that has been captured so far. Accordingly, (i) the image captured in step S4A007 is cleared, (ii) the through display state is set, (iii) the capture frame (4B013a) is then moved, and (iv) the capture frame after the movement (4B013a) The process of (i), (ii) and (iii) is automatically performed with the capture of the capture frame (4B013a) as a trigger without going through the complicated operation of capturing the lower layer image again. It is.

  This makes it possible to capture a user-friendly and simple screen.

  On the other hand, in the state of step S4B013, in the terminal B (4A03), the image (4A007a) captured immediately before by the terminal A (4A01) continues to be displayed or repeatedly in the capture frame at a predetermined position on the screen. It is redisplayed (step S4B013 ′ and screen 4B013 ′).

  The reason for not reflecting the image of the capture frame (4B013a) of the terminal A (4A01) in the capture frame (4B013′a) in the terminal B (4A03) is that the next captured image in the terminal A (4A01) is fixed Until the terminal A (4A01) faithfully displays the image displayed in the capture frame (4B013a) in the capture frame (4B013a) on the terminal A (4A01), This is because it becomes “nuisance” for the operator of B (4A03).

  The reason why the capture frame (4B013′a) is not in the through display state in the terminal B (4A03) is that the terminal A (4A01) displays the image captured immediately before the next image is captured. This is because the terminal B (4A03) is better used for examination.

  Rather, it is sufficient for the terminal A (4A01) to display the image in the capture frame (4B013'a) of the terminal B (4A03) after the next captured image is determined. Of course, the image displayed in the capture frame (3A3B013a) of the terminal A (4A01) may be displayed faithfully in the capture frame (4B013'a) of the terminal B (4A03). What is necessary is just to select suitably so that it may be in any state according to a use.

  On the other hand, if NO in step S4B001 (dragging of the capture frame (4A007a) has not started), the process returns to step S4B009 again to determine whether to capture another image.

  The capture frame displayed through in step S4B013 continues to be dragged in step S4B015. This drag is performed mainly for the purpose of surrounding the image to be captured next by moving a capture frame (4B013a) that is apparently transparent in the frame.

Reference is made to FIG.
Next, in step S4C017, it is determined whether or not the position of the image to be captured is determined by the dragged capture frame (4B013a).

  If NO in step S4C017 (the position of the image to be captured has not been determined), the process returns to step S4B015 again and the dragging of the capture frame (4B013a) is continued.

  If YES in step S4C017 (the position of the image to be captured has been determined), in step S4C019, the drag of the capture frame is released (released), and (a) the latest captured image is redisplayed (screen 4C019a).

  In addition, with the trigger of releasing the drag of the capture frame (4B013a) in the through display state (releasing the mouse) (step S4C019 and image 4C019), “the image captured before dragging” In addition to “Redisplay (Image in 4A007a)”,

(B) Immediately capture the image immediately below the capture frame when released.
Or
(C) maintaining the through display;
It is also possible to configure so as to take the process.

  These modes can be selected and set in advance by the operator, and the corresponding processing is executed accordingly.

  The reason for adopting the above (b) will be described. In (b), using the release as a trigger, the screen below the capture frame (4B013a) that was in the through display state is captured (captured) and is displayed in the frame. The fact that the drag of the capture frame (4B013a) has been released can be considered that the operator of terminal A can infer that he wants to capture the lower layer image surrounded by the capture frame in the released state. It is done.

  In this case, (iv) First, only the capture frame is moved and the drag is released to maintain the through display state. (V) Next, the complicated process of capturing the image displayed in the capture frame. Without performing the above steps, the operations (iv) and (v) are automatically performed collectively by using one action of releasing the draft as a trigger. This is because such an operation matches the intention of the producer of terminal A.

In any of the above cases (a) to (c), terminal B (4A03) continues to display the most recently captured image (4A007a) at terminal A (4A01), as in step S4B015 ′. Has been.
The reason is as described above.

With continued reference to FIG.
Next, in step S4C021, the terminal A (4A01) captures the image displayed in the capture frame (4C021a). In this case, in the terminal B (4A03), the image newly captured by the terminal A (4A01) is displayed in the capture frame (4C021′a) (step S4C021).

  As a result, the terminal B (4A03) can confirm that the terminal A has captured an image different from the previous one.

  Upon completion of the above steps, the exemplary steps of the second embodiment are completed (Step S4C023).

  These flow charts show one exemplary flow that can be adopted in the embodiment of the second embodiment of the present invention. In practice, a flow of processing different from this flow is adopted. obtain. This is because the basic feature of this embodiment is that when the capture frame is started to be dragged (in the case of “Y” in step S4B011), the capture frame is displayed as a through display (step S4B013).

  Another basic feature of the present embodiment is that the terminal B (4A03) reflects the image captured most recently by the terminal A (4A01). This is because unnecessary information can be prevented from being sent to the terminal B. Even if the capture frame is moved, enlarged, or reduced at the terminal A, it is preferable that the terminal B maintains the capture frame at a predetermined position and size. This is because it is convenient for examining the image on the terminal B.

  This embodiment is mainly useful when changing the position of the capture frame without manipulating the image below the capture frame. In other words, the image to be captured is determined, but it is useful for determining which portion of the image to capture.

  The terminal A (4A01) in the through display state (for example, 4B013a) displays the image captured immediately before so as to be thin enough to recognize the lower layer image (not shown). It is also convenient to display the image captured in B so thin that the lower layer image can be recognized (not shown). With such a configuration, it is possible to easily compare an image to be captured in the future with an image captured previously or an image captured by a communication partner.

  Furthermore, a configuration may be adopted in which a memo or the like can be written in the capture frame in a state where an already captured image is displayed in the capture frame (for example, 4A007a) (see FIG. 5). With this configuration, in addition to the lower-level image capturing function, a function that enables writing of predetermined information can be provided.

<Embodiment 2>
In FIG. 1, for example, the system employed in this embodiment is a stand-alone system that does not include the network 2 or the terminal (1B), but includes only the terminal 1A.

  In this embodiment, the screen operation and display modes of the stand alone terminal 1A alone are almost the same as those described in the first embodiment (FIGS. 3A to 3C).

  The difference is that in this embodiment, only the terminal A (3A01) in FIGS. 3A to 3C is targeted, and the terminal B (3A03) is not considered.

  In the present embodiment, the image captured by the terminal A is not reflected on the other terminals, but the desired image is captured in the own terminal and stored in the storage medium. Operations such as capturing and storing in a storage medium are scheduled. Alternatively, the captured image may be written or subjected to predetermined image processing and then stored in a storage medium.

  It is also possible to later send a plurality of images stored in this way to other terminals in the order of storage, so that the terminal as in the first embodiment can be performed. Reflecting the image capture process at A to the terminal B can be realized in a pseudo manner.

  In this embodiment, the screen operation and display modes of the stand alone terminal 1A alone are almost the same as those described in the second embodiment (FIGS. 4A to 4C).

  The difference is that in this embodiment, only the terminal A (4A01) in FIGS. 4A to 4C is targeted, and the terminal B (4A03) is not considered.

  In the present embodiment, the image captured by the terminal A is not reflected on the other terminals, but the desired image is captured in the own terminal and stored in the storage medium. Operations such as capturing and storing in a storage medium are scheduled. Alternatively, the captured image may be written or subjected to predetermined image processing and then stored in a storage medium.

  It is also possible to later send a plurality of images stored in this way to other terminals in the order of storage, so that the terminal as in the second embodiment can be performed. Reflecting the image capture process at A to the terminal B can be realized in a pseudo manner.

  It should be noted that the various display controls described above may be realized by sharing a control program with an operating system (OS).
