A. First Embodiment:
FIG. 1 is an explanatory diagram showing an outline of a network configuration in a network map that visually shows a connection state of devices on a network drawn by a program according to an embodiment of the present invention. In the present embodiment, the network 100 includes a first wireless LAN device 10, a second wireless LAN device 20, a third wireless LAN device 30, a first terminal device CL1, and a second terminal device CL2. It is an area network. In the present embodiment, the wireless LAN devices 10 to 30 and the terminal devices CL1 and CL2 are connected by wireless communication, respectively. However, some may be connected by wire.

The first wireless LAN device 10 is connected to the Internet INT via a cable and has a function as a router. The second wireless LAN device 20 and the third wireless LAN device 30 are connected to the Internet INT via the first wireless LAN device 10. In the present embodiment, for example, the second wireless LAN device 20 performs wireless communication in the 5 GHz band, and the third wireless LAN device 30 performs wireless communication in the 2.4 GHz band.

The terminal devices CL1 and CL2 are devices connected to the Internet INT via the wireless LAN devices 10 to 30. The first terminal device CL1 is wirelessly connected to the first wireless LAN device 10, and the second terminal device CL2 is wirelessly connected to the second wireless LAN device 20. The terminal devices CL1 and CL2 are smartphones in the present embodiment. The terminal devices CL1 and CL2 are not limited to smartphones, but may be personal computers, tablet PCs, or mobile phone devices. In the present embodiment, the first terminal device CL1 executes a network map display program.

FIG. 2 is a block diagram of the first wireless LAN device 10 and the first terminal device CL1 according to the embodiment of the present invention. The first wireless LAN device 10 includes a wireless communication unit 12, a content providing unit 14, and a memory 16. The wireless communication unit 12 communicates with other devices such as wireless LAN devices 20 and 30 and terminal devices CL1 and CL2. In the present embodiment, the content providing unit 14 provides the main body image stored in the memory 16 to another device. The "main body image" is an image showing the appearance of the wireless LAN device. The main body image includes a deformed icon image.

The first terminal device CL1 includes a wireless communication unit C10, a processor C20, a memory C30, a display unit C40, and a camera C50. The wireless communication unit C10 communicates with other devices, for example, wireless LAN devices 10, 20, and 30. The processor C20 executes a network map display program recorded in the memory C30 to perform a network map drawing process described later. The display unit C40 displays a network map.

FIG. 3 is a flowchart showing a network map drawing process according to an embodiment of the present invention. First, the first terminal device CL1 acquires connection information from each of the wireless LAN devices 10 to 30 in step S100. The connection information is, for example, device information such as a model number of each wireless LAN device, a connection destination, a type, an operating system (OS) and a number of connected terminal devices, and information including a connection mode. In the present embodiment, the "connection mode" refers to, for example, the transfer speed of wired communication in connection to the Internet INT, the radio band or frequency of wireless communication, the connection mode such as Bluetooth (registered trademark), or wireless communication. Shows the communication status such as radio wave strength, communication quality, link speed, amount of noise, etc.

Next, the first terminal device CL1 constructs a network map in step S110. In the present embodiment, the first terminal device CL1 displays each wireless LAN device by a main body image. In the present embodiment, the first terminal device CL1 acquires the main body image from the content providing unit 14 of each wireless LAN device. The main body image may be possessed by the first terminal device CL1. Further, the first terminal device CL1 may acquire the main body image from the server on the Internet INT by using the device information of the wireless LAN device acquired in step S100.

FIG. 4 is a diagram showing an example of a network map in step S110. The network map is displayed on the screen D1 of the first terminal device CL1. The wireless LAN devices 10, 20 and 30 correspond to the nodes N1, N2 and N3, respectively. In the present embodiment, the first terminal device CL1 can display the model number MN of each wireless LAN device and the number NT of the terminal devices connected to each wireless LAN device under the main body image BM1.

Steps S120 to S160 are processes for drawing an image of the installation location of the wireless LAN devices 10, 20, and 30 on the network map. First, in step S120, the first terminal device CL1 selects a wireless LAN device to be processed in steps S130 to S160. This selection is made, for example, by tapping one node on the network map. If there is only one wireless LAN device, step S120 may be omitted. Next, in step S130, the first terminal device CL1 sets the installation location of the wireless LAN device selected in step S120. For example, the first terminal device CL1 sets the installation location of the wireless LAN device 10 as "under the stairs". The first terminal device CL1 may be selected from predetermined options as the installation location, or characters indicating the installation location may be directly input.

Subsequently, the first terminal device CL1 causes the location image to be selected in step S140. The "location image" is an image showing the installation location of the wireless LAN device. In the present embodiment, the first terminal device CL1 displays a plurality of candidate images as candidates for location images as options. The location image may be acquired from the wireless LAN device 10. Further, the image captured by the first terminal device CL1 in advance with the camera C50 and stored, or the image captured by the camera C50 may be used.

After selecting the location image, the first terminal device CL1 generates an installation location image in step S150. The "installation location image" is an image including a location image and a main body image of the wireless LAN device. In the present embodiment, the installation location image is an image obtained by synthesizing the main body image and the location image. Details of the generation of the display image will be described later. The installation location image may be an image in which the location image and the main body image are arranged side by side, as long as the installation location of the wireless LAN device and the main body can be visually grasped.

Subsequently, the first terminal device CL1 draws a network map in step S160. More specifically, on the network map constructed in step S110, the wireless LAN device selected in step S120 is drawn and displayed with the installation location image generated in step S150. Finally, the first terminal device CL1 determines in step S170 whether or not the drawing of the network map is completed. When the drawing of the network map is completed, for example, when the installation location image is generated and displayed for all the wireless LAN devices included in the network 100, the network map drawing process is terminated. On the other hand, if the drawing of the network map is not completed, the first terminal device CL1 returns to the process of step S120 and continues drawing the network map. In step S170, the user may be able to select whether or not the drawing of the network map is completed. Further, the information set in the procedure of steps S120 to S140 described above may be stored in the storage device of the first terminal device CL1 and reused for drawing the network map.

FIG. 5 is a diagram showing an example of a network map in which the drawing process of the network map is completed. The installation location image M1 including the main body image BM1 of the first wireless LAN device 10 and the location image PM1 is displayed on the node N1. Similarly, the installation location images M2 and M3 are displayed on the other nodes N2 and N3. In the present embodiment, the installation location PL is displayed below the installation location image M1 instead of the model number MN (FIG. 4) of the wireless LAN device. In addition, only one of the model number MN and the installation location PL may be displayed, or both may be displayed.

FIG. 6 is a flowchart showing an installation location image generation process according to the embodiment of the present invention. Here, the installation location image M1 of the node N1 will be described as an example. First, the first terminal device CL1 determines in step S200 whether or not the color tones of the location image PM1 and the main body image BM1 are similar. The similarity of color tones can be obtained, for example, by the Batacharia coefficient, which is the similarity of histograms. When the color tone similarity is equal to or higher than a predetermined threshold value, the first terminal device CL1 proceeds to step S210 to adjust the color tone of the location image PM1 and reduce the color tone similarity between the location image PM1 and the main body image BM1. .. The color tone is adjusted, for example, by gamma correction or changing the brightness. On the other hand, when the degree of similarity of color tones is less than the threshold value, the first terminal device CL1 proceeds to step S220.

Subsequently, the first terminal device CL1 applies a filter to the location image PM1 in step S220. The filter is preferably smoothed in order to make the main body image stand out from the place image, and for example, a median filter that removes noise in the image, a Gaussian filter that blurs the image using a Gaussian function, or the like can be applied. The entire location image may be smoothed, or only the location image around the main body image when synthesizing in step S230 described later may be smoothed. The order of the color tone adjustment in step S210 and the filtering process in step S220 may be reversed. Further, in order to reduce the degree of similarity in color tone between the location image PM1 and the main body image BM1, only one of the color tone adjustment and the filtering process may be performed.

Finally, the first terminal device CL1 synthesizes the location image PM1 and the main body image BM1 in step S230. Image composition uses, for example, logical operations such as alpha blending and exclusive OR. When the location image PM1 is an image taken by a camera C50 or the like and the first wireless LAN device 10 is reflected, the terminal device CL1 extracts the outline of the first wireless LAN device 10 from the location image PM1. The main body image BM1 may be created, or the installation location image M1 may be created by enlarging the first wireless LAN device 10 portion of the location image PM1.

According to the program of the present embodiment described above, the first terminal device CL1 displays the installation location image including the main body image and the location image of the wireless LAN device on the network map, so that the installation location of the wireless LAN device is set. Easy to grasp.

Further, the installation location image is an image obtained by synthesizing the main body image and the location image, and the first terminal device CL1 performs the color tone adjustment and the filtering process to reduce the similarity of the color tone between the location image and the main body image. Therefore, the installation location of the wireless LAN device can be grasped more easily.

Further, since the first terminal device CL1 acquires the main body image from each wireless LAN device, the main body image of each wireless LAN device can be reliably displayed.

Further, since the first terminal device CL1 displays a plurality of candidate images as candidates for the place image as options, the place image can be surely displayed.

Further, since the first terminal device CL1 displays the number of wireless terminals connected to each wireless LAN device on the network map, the number of wireless terminals connected to the wireless LAN device can be confirmed on the network map.

Further, the wireless communication in the 5 GHz band is represented by two dotted lines L2, and the wireless communication in the 2.4 GHz band is represented by one dotted line L3. The arrow W1 displayed on the node N3 indicates that the wireless connection status between the node N1 and the node N3 is poor. In the present embodiment, "the wireless connection condition is bad" is, for example, a case where the link speed and the signal strength acquired in step S100 of FIG. 3 are lower than a predetermined threshold value. Further, the icon CIM indicates that the terminal device CL1 that performs the network map drawing process is connected to the first wireless LAN device 10. The icon CIM includes rectangles a1 to a3 depending on the radio wave intensity.
