Description

  The present invention relates to a video display apparatus that displays a monitoring video, and more particularly to a video display apparatus that displays a plurality of monitoring videos having different formats.

  Conventionally, when displaying images from a plurality of surveillance cameras, the display area of a video display unit configured with a screen aspect ratio of 4: 3 is divided into four, and four systems with a screen aspect ratio of 4: 3 are monitored. A technique is known in which video is arranged in each divided area of the display area and simultaneously displayed, and the arrangement pattern is stored (see, for example, Patent Document 1).

JP 2008-017529 A

  By the way, in recent years, high-resolution video formats and various screen aspect ratios have been developed in surveillance cameras and the like. Along with this, an increasing number of surveillance systems have a plurality of surveillance videos having different video format specifications.

  In this case, the following problem has occurred. For example, in a monitor with a screen size that supports VGA (resolution is 640 x 480 pixels and screen aspect ratio 4: 3), full high-definition video (resolution is 1920 x 1080 pixels and screen aspect ratio is 16: 9) Is displayed. Then, since the screen aspect ratio differs between VGA and full high-definition, when a full high-definition video is displayed in accordance with the horizontal width of the VGA, useless areas where no video is displayed on the top and bottom of the screen are generated. On the other hand, when a full high-definition video is displayed in accordance with the VGA screen height, the left and right sides of the video are deleted and the entire video cannot be displayed. In either case, since the display is performed with the resolution lowered by about 1/3 to 1/2, the original high resolution display of the full high-definition video cannot be utilized. On the contrary, if the screen size of the display unit is made compatible with full high-definition, a similar problem occurs when displaying VGA video.

  However, in the technique of Patent Document 1, in order to display a monitoring video in a predetermined format in a display area designed in accordance with the format of the monitoring video, a plurality of monitoring videos having different formats can be freely displayed in the display area. I couldn't.

  The present invention has been made in view of the above problems, and an object thereof is to provide a technique for freely displaying a plurality of monitoring videos having different formats in a display area.

  The video display device of the present invention is a video display device that arranges and displays a plurality of monitoring videos in an arrangement area, and an arrangement position that allows the arrangement position of the displayed monitoring video to be freely set to an arbitrary position A change means is provided.

  According to the present invention, a plurality of monitoring videos having different formats can be freely displayed in the display area.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  First, the overall configuration of the image storage / delivery system will be described with reference to FIG. The image storage / delivery system includes a plurality of WEB cameras 2 (2-1 to 2-n), an image storage / delivery server 1, a plurality of client terminals 4 (4-1 to 4-m), and a network 3. The image storage / delivery server 1, the plurality of WEB cameras 2, and the plurality of client terminals 4 are connected via a network 3.

  Each of the WEB cameras 2-1 to 2-n has a unique channel number. For example, the WEB camera 2-1 has a channel number Ch1, the WEB camera 2-2 has a channel number Ch2,. A channel number Chn is assigned to the camera 2-n. The WEB camera 2 transmits a monitoring video obtained by photographing the monitoring space to the image storage / delivery server 1 via the network 3. The monitoring video may be compressed by, for example, JPEG and transmitted to the image storage / delivery server 1 in the IP packet format.

  FIG. 2 is a functional block diagram showing the configuration of the image storage / delivery server 1. The image storage / delivery server 1 includes a network interface 11, a processor 12, a program storage memory 13, a table storage memory 14, a data storage memory 17, a disk interface 15, and a disk device 16.

The network interface 11 is an interface for connecting to the network 3.
The disk interface 15 is an interface for connecting to the disk device 16.
The disk device 16 has channel-specific (site-specific) storage areas 160, for example, a ch1 storage area 160-1, a ch2 storage area 160-2,..., A chn storage area 160. -N. The disk device 16 may be configured separately from the image storage / delivery server 1.

The program storage memory 13 stores various control programs executed by the processor 12.
The table storage memory 14 stores the camera information of each WEB camera 2 and the storage area 160 for each channel that is a storage destination of the monitoring video of each WEB camera 2 in association with each other. The camera information of the WEB camera 2 includes the name of each WEB camera 2, the channel number, the frame number of the recorded monitoring video, the recording state information (whether or not recording is performed), and the like. The recording status information is updated by the processor 12 periodically checking whether each WEB camera 2 is recording via the network 3. In addition, the table storage memory 14 stores layout information of an arrangement area described later in association with user information.
The data storage memory 17 is used as a buffer area for monitoring video transmitted / received via the network 3 and a cache area when writing / reading processing is performed on the disk device 16.

  The processor 12 reads out various control programs stored in the program storage memory 13, develops them in a RAM (not shown), and executes them, thereby controlling each part of the image storage / delivery server 1, as well as the image storage / delivery server 1. Realize the function.

  When the processor 12 acquires the monitoring video of the WEB camera 2 via the network 3 and the network interface 11, the processor 12 stores the monitoring video in the storage area 160 of the disk device 16 corresponding to the channel number of the WEB camera 2.

  Further, the processor 12 displays the monitoring video stored in the storage area 160 on the display unit of the client terminal 4 via the network 3 in response to a request from the client terminal 4. The processor 12 may perform user authentication when displaying the monitoring video on the client terminal 4. The processor 12 reads layout information of an arrangement area corresponding to the authenticated user from the table storage memory 14 and follows the layout information. The monitoring video may be displayed in the layout.

  The client terminal 4 includes a display unit and an operation unit (not shown). For example, a monitoring video stored in the image storage / delivery server 1 is acquired via the network 3 on a WEB browser, and the monitoring video is displayed on the display unit. Play.

  FIG. 3 is an example of a screen for reproducing the monitoring video on the client terminal 4 and shows a display area 500 of a display unit (not shown) in the client terminal 4. In the display area 500, a monitoring video list 200, an arrangement area 600, and an arrangement save button 400 are displayed. The monitoring video list 200 displays a list of currently displayed monitoring videos. For example, the monitoring cameras A to D display the name of the WEB camera 2 that is currently recording based on the recording state information in the table storage memory 14, indicating that real-time monitoring video can be displayed. The recorded videos E and F indicate the names of the monitoring videos stored in the storage area 160. The monitoring video displayed in the monitoring video list 200 corresponds to conditions specified in advance by the user, for example, the channel number of the WEB camera 2, the frame number of the monitoring video, the recording time, and the like.

  In the arrangement area 600, the monitoring video selected by the user from the monitoring video list 200 is arranged and displayed as the arrangement video 61. In the arrangement area 600, additional information such as a still image 62 and an illustration 63 desired by the user can be displayed. The arrangement save button 400 is the layout information in the arrangement area 600, that is, the contents information arranged in the arrangement area 600 (arranged video 61, still image 62, illustration 63, etc.) and the arrangement of the contents in the arrangement area 600. This button saves the position. When the save layout button 400 is pressed, the processor 12 stores the layout information of the placement area 600 in the table storage memory 14. Therefore, for example, when the client terminal 4 is restarted, the monitoring video can be displayed in the arrangement area 600 based on the layout information read from the table storage memory 14. In the following description, examples of various display areas, arrangement areas, and arrangement videos will be described. However, the display area 500 will be described only when the display areas are not distinguished, and only when the arrangement areas are not distinguished. The arrangement area 600 will be described, and in particular, the arrangement video 61 will be described when each arrangement video is not distinguished.

  First, the user selects a desired monitoring video from the monitoring video list 200 via the client terminal 4. The user can select the monitoring video by moving the mouse over the desired monitoring video in the monitoring video list 200. Next, the user drags the selected monitoring video and drops it at a position to be arranged in the arrangement area 600. As a result, the monitoring video selected by the user is arranged at the dropped position and displayed as the arrangement video 61. In FIG. 3, each of the monitoring camera A, the monitoring camera B, the monitoring camera C, the monitoring camera D, and the recorded video E in the monitoring video list 200 is selected and dragged and dropped into the arrangement area 600. It corresponds to each of video A, video B, video C, video D, and video E. The user can arrange a desired still image 62, for example, a floor plan of the monitoring video list 200 on which each WEB camera 2 is installed, at a desired position in the arrangement area 600 by, for example, copy and paste. Further, the user draws an arrow as an illustration 63 in the arrangement area 600, and associates each of the images A to E arranged in the arrangement area 600 with the still picture 62 (plan view) by the arrow, and the still picture 62 (plan view). In the above, the installation locations of the images A to E can be pointed out in an easy-to-understand manner with arrows. In addition to the arrows, the illustration 63 includes various figures such as lead lines and balloons, characters, lines, and the like.

  The layout area 600 changes its shape and size automatically or by user operation in accordance with the display area 500. For example, when the client terminal 4 accesses the image storage / delivery server 1, the processor 12 acquires the size of the display area 500 of the client terminal 4 and sets the arrangement area 600 having a size matching the size of the display area 500. It can be displayed on the client terminal 4. And the processor 12 should just be comprised so that the size and shape of the displayed arrangement | positioning area | region 600 can be changed according to a user's operation via the client terminal 4. FIG.

  For example, as illustrated in FIG. 4A, an arrangement area 601 in which four arrangement videos 61 can be arranged is provided in the display area 501. 4B, a display area 502 larger than the display area 501 in FIG. 4A is provided with an arrangement area 602 in which nine arrangement images 61 can be arranged in accordance with the size of the display area 502. Yes. Also, as shown in FIG. 4C, when a display area 503 and a display area 504 are newly added by a sub monitor, an arrangement area 603 is added to each of the new display area 503 and the display area 504. An arrangement region 604 can be provided. In this way, by enlarging, reducing, or deforming the arrangement area 600 in accordance with the shape and size of the display area 500, the display area 500 that changes according to the resolution and the number of screens can be used without waste, and a large number of monitoring images can be obtained. Can be effectively used for displaying a list of high-resolution images.

  The arrangement of the arrangement video 61 in the arrangement area 600 will be described in more detail. In FIG. 5A, four types of monitoring video are arranged in each divided area obtained by virtually dividing the arrangement area 601 into four, and the VGA arrangement videos 611 and 16: 9 are arranged with a screen aspect ratio of 4: 3. This is an example in which an installed full HD arrangement video 612, a 16: 9 vertical installation full HD arrangement video 613, and a 16: 9 diagonal installation full HD arrangement video 614 are arranged. A VGA monitoring video 611 having a screen aspect ratio of 4: 3 is arranged on the upper right of the arrangement area 601 and is arranged in a quarter area of the arrangement area 601 without waste. On the other hand, in the upper left of the arrangement area 601 where the 16: 9 horizontally installed full HD monitoring video 612 is arranged, a useless area is generated vertically, and the 16: 9 vertically installed full HD monitoring video 613 is arranged. In the lower right of the arrangement area 601, useless areas are generated in the left and right, and in the lower left of the arrangement area 601 in which the 16: 9 diagonal full HD monitoring video 614 is arranged, useless empty areas are generated in the upper, lower, left, and right. ing.

  Thus, as shown in FIG. 5B, the arrangement position of the 16: 9 horizontal full HD arrangement video 612 is adjusted by adjusting the arrangement position so as to match the upper side of the arrangement area 601. Unnecessary free space can be crushed. Further, with respect to the arrangement position of the 16: 9 vertically installed full HD arrangement image 613, the arrangement position is adjusted so as to match the right side of the arrangement area 601 so that a useless empty area generated on the right side can be crushed. it can. Also, the 16: 9 diagonal full HD arrangement video 614 is arranged so that a part of the arrangement video 614 is hidden behind the arrangement video 612 by shifting the arrangement position upward. Thereby, a collective empty area 60 can be secured, and a new arrangement video 61, still picture 62, etc. can be arranged in this empty area 60.

  The user not only can freely move the arrangement video 61 arranged in the arrangement area 600 in the arrangement area 600 but also creates a cut-out area in which a part of the video area of the arrangement video 61 is cut out. Hereinafter, when it is not necessary to distinguish each cutout area, it is possible to arrange the cutout area 610) in the arrangement area 600. FIG. 6 is an image diagram in which the user cuts out the arrangement video and rearranges it in the arrangement area. In the 16: 9 vertical full HD arrangement video 613 in FIG. 6A, the central portion of the video area is cut out into a rectangle by a cut-out area 610b, and cut out into the arrangement area 601 shown in FIG. 6B. It is arranged as 610b. Also, the 16: 9 diagonal full HD arrangement image 614 shown in FIG. 6A is cut out into a substantially square shape by the cutout area 610a at the center of the image area, and the arrangement area shown in FIG. The cutout area 610a is arranged at 601. Further, the arrangement position of the 16: 9 horizontal full HD arrangement video 612 shown in FIG. 6A is adjusted so as to be aligned with the upper side of the arrangement area 601 and shown in FIG. 6B. As described above, the space is rearranged so that the useless empty area generated on the monitoring video 612 is crushed. In this way, the cutout area 610 can secure a wider empty area 60, and a new arrangement video 61 or the like can be arranged in the empty area 60.

  Further, the vertical or / and horizontal size of the arrangement image 61 may be set freely. For example, FIG. 7 is an image diagram showing a state in which the horizontal size in the 16: 9 horizontal installation video 612 is changed to a scale different from the vertical size and arranged in the arrangement area 601.

  In FIG. 7A, switching lines 620a and 620b are provided for the 16: 9 horizontally arranged image 612. The switching line 620a is used to change the size of the arrangement video 612 to 4: 3 ratio by simply linearly compressing the arrangement image 612 in the left direction from the set position in the horizontal direction. In addition, the switching line 620b is a simple linear compression of the arrangement image 612 in the right direction from the set position to change the size of the arrangement image 612 to a 4: 3 ratio. Here, simple linear compression refers to compressing the compression target area at the same compression rate. FIG. 8 is an image diagram illustrating the compression rate of the arrangement video 612 in the horizontal direction. As shown in FIG. 8A, by performing simple linear compression on the image area from the both ends of the arrangement video 612 to the switching lines 620a and 620b, the accuracy with respect to the drawing of the subject (whether the line is bent is straight). Or the like). As shown in FIG. 8 (b), when a 16: 9 video is displayed on a 4: 3 ratio screen, it is continuous in the horizontal direction as it approaches both ends of the arranged video 612 without simple linear compression. If the image is compressed and displayed at a different compression rate, the accuracy of the drawing of the subject cannot be determined, which is not suitable for monitoring purposes. Therefore, here, simple linear compression is performed so that the shape of the subject can be accurately grasped.

  Returning to FIG. 7A, the arrangement video 612 ′ is obtained by changing the size from the 16: 9 ratio to the 4: 3 ratio by performing simple linear compression with the switching lines 620 a and 620 b as a boundary. In the arrangement video 612 ′, the switching lines 620a and 620b are clearly shown. Thus, as shown in FIG. 7C, for example, when a 16: 9 arrangement video 612 is arranged on a four-division screen based on a 4: 3 image, a wasteful portion is generated vertically and the whole is reduced. However, according to the arrangement video 612 ′ that is simply linearly compressed with the switching lines 620a and 620b as a boundary, it can be arranged without waste without reducing the resolution of the necessary portion. . Here, as an example, the switching lines 620a and 620b are respectively set to 1/4 positions from the left and right of the arrangement video 612, but can be set to free positions such as 1/3. For example, for an important subject, the switching lines 620a and 620b can be moved so as not to compress a portion where the subject is reflected.

  Further, as shown in FIG. 7 (b), the entire arrangement image 612 is simply linearly compressed in the horizontal direction with respect to the arrangement image 612 of 16: 9 horizontally installed, and the arrangement image 612 ′ corresponding to the 4: 3 ratio is obtained. 'May be generated. Even in this case, as shown in FIG. 7C, the arrangement video 612 ″ can be arranged on the 4: 3 ratio screen without waste. 7A and 7B, the case where the horizontal size of the arrangement video 612 is changed has been described as an example. However, the vertical size and the diagonal size can be changed, for example, You may arrange | position by changing the size of the vertical direction of the arrangement | positioning image | video 613 of 16: 9 vertical installation.

  Further, the arrangement image 61 may be three-dimensionally rotated and arranged in the arrangement area 600. For example, FIG. 9 is an image diagram of a display area in which four arrangement videos 61 corresponding to the cameras 2 to 5 among the cameras 1 to 5 are displayed by being three-dimensionally rotated. In FIG. 9A, the arrangement video 615 of the camera 1 is arranged in front of the display area, and the arrangement pictures 616 to 619 of the cameras 2 to 5 are arranged on the left, right, and top of the display area, respectively. As shown in FIG. 9B, the arrangement image 615 of the camera 1 at this time is an arrangement of the image on the xy plane as it is without being rotated. On the other hand, the arrangement video 616 of the camera 2 is obtained by arranging an image obtained by rotating the image on the xy plane with respect to the x axis, and the arrangement video 617 of the camera 3 is rotated with respect to the y axis. The images are arranged. The arrangement video 618 of the camera 4 is an arrangement of an image obtained by rotating an image on the xy plane in the opposite direction to the arrangement video 617 of the camera 3 with respect to the y axis. The arrangement video 619 of the camera 5 is an arrangement of an image obtained by rotating an image on the xy plane in the opposite direction to the arrangement video 616 of the camera 2 with respect to the x axis. As a result, the arrangement image 61 is displayed in a three-dimensionally projected manner in the display area 500 because the arrangement image 61 is three-dimensionally rotated and arranged. In addition, although the example which rotated the arrangement | positioning image | video 61 with respect to the x-axis and the y-axis was shown here, you may arrange | position by rotating the arrangement | positioning image | video 61 with respect to the z-axis.

  In addition, the cutout area 610 may be cut out from a range that spans the plurality of arrangement videos 61. FIG. 10A is an image diagram for creating a cutout area from an arrangement area in which a plurality of arrangement videos are arranged. As shown in FIG. 10A, monitoring video H to monitoring video N are arranged as the placement video 61 in the placement area 605. The cutout area 610c extends over the video H, the video K, and the video I, and the cutout area 610e extends over the video L, the video M, and the video N. The cutout area 610d is cut out from the video area of the video M only.

  As shown in FIG. 10B, the user can also display the cutout area 610c to the cutout area 610e on the entire display area 500. This is because an arrangement area 600 wider than the physical display area 500 of the display unit of the client terminal 4 is virtually defined, and an arbitrary range of the arrangement area 600 is designated by the cutout area 610 and is displayed in the display area 500. To display. At this time, if the cutout area 610 is specified to be small, a higher-definition arrangement video 61 can be displayed in the display area 500. Conversely, if the cutout area 610 is specified to be large, the definition of the arrangement video 61 is reduced. In addition, it is possible to improve the listing for a plurality of arrangement images 61. Further, the entire arrangement range can be displayed in the display area 500 by matching the cutout area 610 to the arrangement range of the arrangement image 61 in the arrangement area 600.

  In addition, a plurality of cutout areas 610 may be assigned to one display area 500 to change the display content of the display area 500. This assignment change may be performed manually or automatically according to a preset schedule. In addition, switching from one cutout area 610 to the next cutout area 610 may be switched at a time, or may be switched with a transition effect so as to shift continuously or deformed. In this way, a plurality of cutout areas 610 can be displayed cyclically, and the listability and accessibility to a large number of arrangement videos 61 can be improved. It goes without saying that different display areas 610 may be displayed in each display area 500 using a plurality of display areas 500 by a multi-monitor or the like.

  Further, a plurality of arrangement areas 600 may be provided in one display area 500 so that the arrangement video 61 can be laid out in each arrangement area 600. FIG. 11 shows an example of a screen in which three display areas 605 to 607 are provided in one display area 505. The arrangement area 607 is laid out from the viewpoint of video monitoring regarding the xx building, and is registered in the table storage memory 14 as the pattern A. The arrangement area 605 is laid out for the purpose of displaying a list of all monitoring videos, and is registered in the table storage memory 14 as a pattern B. In the arrangement area 606, representative videos of the base videos are laid out and registered in the table storage memory 14 as a pattern C. The screen display of each of the arrangement areas 605 to 607 is configured to be switchable with tabs. In FIG. 11, the tab portion on which the pattern A is displayed is displayed in the foreground because it is currently selected. As described above, the layout information of the plurality of arrangement areas 600 is stored in the table storage memory 14 and the layout information is switched and displayed, so that the display unit having the display area 500 can be shared among a plurality of users and various operation modes. can do. In FIG. 11, an example in which the arrangement areas 605 to 607 can be switched by tabs has been described. However, a plurality of arrangement areas 600 may be configured to be switchable by a user interface such as a button or a menu.

  As described above, according to the present embodiment, the arrangement video 61 is freely arranged at an arbitrary position in the arrangement area 600 provided in accordance with the display area 500, and the arranged arrangement video 61 is cut out or enlarged. By reducing, moving, or rotating, the layout in the arrangement area 600 can be freely changed. Therefore, it is possible to display a lot of arrangement videos 61 having different formats, and it is possible to make the display easy to see according to the needs of the user. In addition, in the empty area 60 secured by changing the layout of the arrangement video 61 arranged in the arrangement area 600, a new monitoring video 61, a description of the monitoring video 61, a still image 62 such as a warning and an advertisement, an illustration 63, etc. Since the additional information can be added, the convenience of the user and the added value of the entire display can be increased.
