  In a multi-display system, generally, a plurality of displays having the same number of pixels per unit area of the video display surface are usually arranged. However, as described in Non-Patent Documents 1 and 2, it is technically possible to construct a multi-display system by combining displays having different sizes and pixel numbers.

  When displays of different sizes and number of pixels are arranged adjacent to each other, it seems that there is not much visual discomfort if each display displays different images. However, when each adjacent display displays a part of a single image and the single image is displayed as a whole multi-display system, the resolution of the image changes sharply at the boundary between the displays, and the image is displayed. It is thought that there may be a sense of discomfort for the viewer.

  The present invention has been made in view of the problems as described above, and aims to alleviate a sense of incongruity given to a viewer of a video in a multi-display device using a plurality of displays having different sizes and pixel numbers. To do.

  The multi-display apparatus according to the present invention displays an image that has been subjected to conversion processing that changes the number of pixels per unit area in a stepwise manner at a boundary portion between displays.

  According to the multi-display device according to the present invention, even when a plurality of displays having different sizes and the number of pixels are used, it is possible to reduce visual discomfort at the boundary between the displays.

<Discomfort at the boundary between displays>
Hereinafter, in order to facilitate understanding of the present invention, first, the visual discomfort regarding the boundary between displays in a multi-display device will be described. Thereafter, an embodiment of the present invention will be described.

  FIG. 1 is a diagram showing a screen configuration example of a multi-display device in which two displays having the same video display surface size and different number of pixels are arranged adjacent to each other. As shown in FIG. 1A, the number of pixels of the right display as viewed in the drawing is 1024 × 768 pixels, and the number of pixels of the left display is 2048 × 1536 pixels. FIG. 1B is a diagram schematically illustrating the difference in the number of pixels using a black and white mosaic. The number of pixels per unit area of the video display surface changes sharply at the boundary between the two displays.

  FIG. 2 is a diagram illustrating a screen configuration example of a multi-display apparatus in which three displays having different video display surface sizes and the same number of pixels are arranged adjacent to each other. As shown in FIG. 2A, the number of pixels of each display is 1024 × 768 pixels, but the number of pixels per unit area is different because the size of the video display surface is different. As shown in FIG. 2B, even in this case, the number of pixels per unit area of the video display surface is steep at the boundary portion between the two displays on the left side and the right display on the drawing. Has changed.

  FIG. 3 is an example of a video illustrating the visual discomfort caused by a sharp change in the number of pixels per unit area of the video display surface at the boundary between the displays. Here, an example is shown in which two displays arranged side by side display a part of a single video, and the single video is displayed as the entire multi-display device.

  As shown in FIG. 3, the left display displays a fine image with a large number of pixels per unit area, whereas the right display displays a coarse image with a small number of pixels per unit area. Therefore, a sense of incongruity that the resolution of the video changes sharply occurs at the boundary between the displays, which is not desirable for the viewer.

  In the multi-display apparatus using a plurality of displays having different numbers of pixels per unit area as described above, the present invention aims to reduce the above-mentioned visual discomfort regarding the boundary portion between the displays.

<Embodiment 1>
FIG. 4 is a configuration diagram of the multi-display device 100 according to the first embodiment of the present invention. The multi-display device 100 includes displays 110 and 120 and a control device 130.

  The displays 110 and 120 are arranged so that their video display surfaces are adjacent to the left and right. The size of the image display surface of the display 110 and the size of the image display surface of the display 120 are the same. The number of pixels of the display 110 is 2048 × 1536 pixels, and the number of pixels of the display 120 is 1024 × 768 pixels. Therefore, the visual discomfort described with reference to FIGS. 1 to 3 may occur at the boundary between the displays 110 and 120.

  The control device 130 controls the operations of the displays 110 and 120. For example, the control device 130 divides a single video, assigns a divided portion to each display, and supplies a video signal of the divided portion to each display.

  FIG. 5 is a diagram schematically illustrating how the number of pixels per unit area is gradually decreased toward the boundary portion. In the video displayed on the display 110, the number of pixels per unit area gradually decreases in accordance with the boundary portion between the display 110 and the display 120. For example, the region 111a has the number of pixels per unit area that the display 110 originally has, the region 111c has the same number of pixels per unit area as the display 120, and the region 111b is intermediate between them. The configuration pattern of the number of pixels per unit area is not limited to the example illustrated in FIG. 5, and other configuration patterns may be used as long as the number of pixels gradually decreases toward the boundary portion.

  As a technique for reducing the number of pixels per unit area, for example, it is conceivable to average a plurality of adjacent pixel values (for example, each RGB value in the case of a pixel expressed by an RGB value). In the example shown in FIG. 5, two adjacent pixel values are averaged in the region 111b, and four adjacent pixel values are averaged in the region 111c. The effect as shown in FIG. 5 can be exhibited by gradually increasing the number of pixels to be performed. The method of reducing the number of pixels is not limited to this, and other methods may be used as long as the same effect can be exhibited.

  When the display 110 displays an image with a reduced number of pixels per unit area, the control device 130 can supply the image to the display 110, or the display 110 itself can display pixels as illustrated in FIG. The number can also be reduced. That is, the process for converting the number of pixels illustrated in FIG. 5 may be performed by the control device 130 or the display 110. When the display 110 performs the conversion process, it may be performed based on the judgment of the display 110 itself or according to an instruction from the control device 130.

  FIG. 6 is a diagram illustrating a result of performing the conversion process for reducing the number of pixels described in FIG. 5 on the video in FIG. The number of pixels per unit area in the left part of the drawing gradually decreases as it approaches the boundary part. Therefore, as compared with FIG. 3, the change in the number of pixels at the boundary between the displays 110 and 120 is moderate, and the visual discomfort for the viewer who watches the video is alleviated.

<Embodiment 1: Summary>
As described above, in the multi-display device 100 according to the first embodiment, the display 110 displays an image in which the number of pixels per unit area is reduced as the boundary with the display 120 is approached. Thereby, it is possible to relieve the visual discomfort caused by the sharp change in the number of pixels per unit area at the boundary portion. Furthermore, by using together the display 120 having a small number of pixels per unit area, the cost of the entire multi-display device 100 can be suppressed.

  In the first embodiment, it has been described that the displays 110 and 120 have the same image display surface size and different pixel numbers as in FIG. 1, but the image display surface size differs and the number of pixels as in FIG. Even if they are the same, the same effect can be obtained by performing the same conversion process as in the first embodiment on the video of the display having a large number of pixels per unit area. The same applies to the following embodiments.

  In the first embodiment, when there is a possibility that a display having a smaller number of pixels per unit area of the image display surface than the display 120 may be arranged on the right side of the display 120 toward the drawing, the display 120 is the same as the display 110. It is also possible to display an image that has been subjected to the conversion process. The same applies to the following embodiments.

<Embodiment 2>
Since the multi-display device 100 is a device for providing a large screen, if the displays 110 and 120 are always placed side by side, a large storage space is required, which is inconvenient. Therefore, these displays may be arranged adjacent to each other only during operation, and the displays may be separated and accommodated during other periods. When the multi-display device 100 is operated, these displays are newly arranged adjacent to each other.

  When the displays are arranged adjacent to each other, which display is arranged at which position may not always be determined. For example, in the first embodiment, the display 110 having a large number of pixels per unit area is arranged on the left side in the drawing, but may be arranged on the right side in the next operation opportunity. Furthermore, at the next operation opportunity, a display having the same number of pixels per unit area as that of the display 110 may be arranged adjacently, and conversion processing may be unnecessary.

  Therefore, in the second embodiment of the present invention, the number of pixels per unit area of the display arranged adjacent to the display 110 and the position where the display is arranged are dynamically obtained and used for the conversion processing of the number of pixels. A configuration example to be reflected will be described.

  FIG. 7 is a configuration diagram of the multi-display device 100 according to the second embodiment. In the second embodiment, the display 110 includes RFID (Radio Frequency IDentifier) reader devices 112a to 112d, and the display 120 includes RFIDs 122a to 122d. For convenience of explanation, the displays 110 and 120 are not in contact with each other in FIG. 7, but when the multi-display apparatus 100 is actually operated, these displays are disposed in contact with each other as in the first embodiment.

  The RFIDs 122 a to 122 d store data representing the number of pixels per unit area of the video display surface of the display 120. For example, the size of the video display surface and the number of pixels, or the number of pixels per unit area can be stored. Each RFID 122a-122d can be placed at a location that is expected to be adjacent to another display. For example, it can be arranged on the left and right side surfaces of the video display surface, the bottom surface and the top surface of the video display surface, and the like.

  The RFID reader devices 112a to 112d are devices that can read data stored in the RFIDs 122a to 122d. Each RFID reader device 112a-112d can be placed at a location that is expected to be adjacent to another display. For example, like the RFIDs 112a to 112d, they can be arranged on the top, bottom, left and right sides of the video display surface.

  When an operator who installs the multi-display device 100 installs each display, the RFID reader devices 112a to 112d that are arranged adjacent to the display 120 read data by approaching any one of the RFIDs 122a to 122d. It will be. Thereby, the number of pixels per unit area of the video display surface of the display 120 actually installed at the operation site can be dynamically acquired.

  When the control device 130 performs the conversion processing described with reference to FIG. 5, the control device 130 uses the number of pixels read by the RFID reader device 112 (or data from which this can be derived) to determine whether to perform the conversion processing. And the extent of the conversion process can be determined. When the number of read pixels is smaller than that of the display 110, the same conversion process is performed.

  Furthermore, by identifying which of the RFID reader devices 112a to 112d has read the number of pixels, the direction in which the conversion process is performed can be determined. For example, if the RFID reader device 112a has read the number of pixels, the number of pixels may be decreased from the center of the image display surface of the display 110 toward the right end as viewed in the drawing. In order to identify which of the RFID reader devices 112a to 112d has read the number of pixels, for example, the number of each RFID reader device 112 may be acquired together. Communication between the RFID reader device 112 and the control device 130 may be performed via an appropriate communication network.

  When the display 110 itself performs the conversion process described with reference to FIG. 5, the control device 130 supplies an image that has not been subjected to the conversion process to the display 110, and the display 110 itself performs the same processing as the control device 130 described above. Just do it. Whether or not to perform the conversion process and its direction may be instructed based on the data acquired from the RFID reader device 112 by the control device 130, or determined based on the data acquired by the display 110 itself from the RFID reader device 112. May be.

<Embodiment 2: Summary>
As described above, the multi-display device 100 according to the second embodiment includes the RFID 122 that stores the number of pixels per unit area of the video display surface of the display 120, and further includes the RFID reader device 112 that reads the RFID 122. Thereby, it is possible to dynamically adjust whether or not to perform the pixel number conversion process on the video displayed on the display 110 and the direction of the conversion process.

  In FIG. 7, the display 110 includes the RFID reader device 112 on each of the top, bottom, left, and right surfaces, and the display 120 includes the RFID 122 on each of the top, bottom, left, and right surfaces. For example, in the case where only the RFID reader device 112a and the RFID 122c are provided, the effect of the present invention can be exerted at least when the arrangement relationship as shown in FIG. 7 occurs.

  In the second embodiment, RFID is used as a device for storing the number of pixels of the display 120. However, the same effect can be exhibited even by a device other than RFID. However, in consideration of convenience during installation work, it is considered convenient to use RFID that can be read only by bringing the reader device and the ID chip close to each other.

  As a device other than the RFID, for example, a device that communicates by NFC (Near Field Communication) and its reader device are conceivable. Alternatively, data representing the number of pixels of the display 120 is described on a barcode (in this case, a pixel number presentation device) and pasted on each side of the display 120, and the display 110 includes a barcode reader that reads the barcode. May be. Even with these configurations, the same effects as those of the second embodiment can be exhibited.

  Since RFID reads data by bringing a reader device closer (or by bringing RFID closer to the reader device), it is convenient from the viewpoint that data can be read when the displays approach each other during installation work. On the other hand, for example, when a wireless method that does not require a reader device such as a wireless LAN device is used, the process of determining which side a display with a small number of pixels is arranged adjacent to is complicated (for example, radio waves) It is necessary to judge the position using intensity etc.). Therefore, the method of the second embodiment in which the reader device is brought closer to the RFID is considered more convenient.

  In the second embodiment, the display 110 includes the RFID reader device 112, and the display 120 includes the RFID 122. For example, a display with a larger number of pixels per unit area is arranged on the left side of the display 110 toward the drawing. If possible, an RFID storing the number of pixels per unit area of the video display surface of the display 110 may be disposed on the left side surface of the display 110. Similarly, an RFID reader device may be arranged on the right side surface of the display 120, for example. The same applies to the other surfaces of each display.

  In the second embodiment, it has been described that the display 120 includes some device for presenting the number of pixels on the outer surface portion, and the display 110 includes the reader device. In consideration of the possibility that various displays may be installed in actual operation situations, both displays 110 and 120 may include a pixel number presentation device and its reader device.

<Embodiment 3>
In the second embodiment, the number of pixels per unit area of the image display surface of the display 120 is acquired by the RFID reader device 112 and the RFID 122. Instead of using the RFID reader device 112 and the RFID 122, for example, manual input is performed. The number of pixels per unit area can also be specified by. For example, this may be realized by setting the setting interface of the display 110 itself, or the same may be performed by the operation interface of the control device 130.

  Similarly to the above, the direction in which the process of converting the number of pixels is performed can also be specified by manual input. For example, it can be specified to decrease the number of pixels in the direction from the center of the display 110 toward the right end (toward the drawing). The direction of the conversion process itself may be specified, or the position of the boundary portion with the display having a small number of pixels may be specified. This designation may be realized by setting through the setting interface of the display 110 itself, or the same may be carried out through the operation interface of the control device 130.

<Embodiment 4>
FIG. 8 is a diagram showing a display arrangement in the multi-display device 100 according to Embodiment 4 of the present invention. In the case where the video display surface of the multi-display device 100 is arranged vertically, consider a case where the display size of the multi-display device 100 as a whole is larger than the height of a human being, for example, a large display installed outdoors.

  In this case, it is assumed that the human line of sight will be mostly concentrated within his height. Therefore, by arranging a display having a large number of pixels per unit area within the range, it is possible to display a portion where the line of sight concentrates with higher definition than other portions. Specifically, it is desirable that at least a part of the image display surface of the display having a large number of pixels per unit area is included in a range of approximately 50 cm to 250 cm in the vertical direction from the installation surface of the multi-display device 100.

<Embodiment 5>
FIG. 9 is a diagram showing a display arrangement in the multi-display device 100 according to the fifth embodiment of the present invention. Even in the case of a large display as described in the third embodiment, when the person viewing the image is away from the multi-display device 100 or when displaying a rapidly changing image, the line of sight is displayed on the multi-display device 100. It is assumed that it is concentrated near the center of the surface. For example, a display that displays a performance pattern at a concert venue, a display that displays the progress of a race at a racetrack, and the like correspond to this.

  In this case, it is desirable to arrange each display so that the video display surface of the display having a large number of pixels per unit area includes the center of the video display surface of the multi-display device 100. Thereby, it is possible to display a portion where the line of sight concentrates with higher definition than other portions.

<Modification of the present invention>
The present invention is not limited to the above-described embodiments, and includes various modifications. For example, the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described. Further, a part of the configuration of a certain embodiment can be replaced with the configuration of another embodiment, and the configuration of another embodiment can be added to the configuration of a certain embodiment. In addition, it is possible to add, delete, and replace other configurations for a part of the configuration of each embodiment.

  For example, in the above embodiment, the number of pixels of the display 110 is 2048 × 1536 pixels and the number of pixels of the display 120 is 1024 × 768 pixels. However, the number of pixels of the display is not limited thereto.
