In step S910, the connection information acquisition unit 260 of the wireless communication terminal 200 requests the connection information from the image processing device set as the connection target. When the connection processing unit 262 of the wireless communication terminal 200 acquires the connection information (for example, SSID, password, IP address, etc.) transmitted by the image processing device set as the connection target, the connection processing unit 262 uses the connection information to obtain the connection information.

<Functional configuration of the present embodiment>
Next, the functional configuration will be described. FIG. 10 is a functional block diagram of the wireless communication terminal 500. The wireless communication terminal 500 includes a first transmission / reception unit 552, a second transmission / reception unit 554, a reception signal strength measurement unit 556, a connection target identification unit 558, a connection information acquisition unit 560, a connection processing unit 562, a job request unit 564, and storage. It has a read processing unit 566 and a tilt detection unit 572. Each of these parts is a function or means realized by operating any of the components shown in FIG. 6 by a command from the CPU 202 according to a program for a wireless communication terminal stored in the HDD 208. .. Further, the wireless communication terminal 500 has a storage unit 568 constructed by the HDD 208 shown in FIG.

<Each functional part of wireless communication terminal 500>
Next, each part of the wireless communication terminal 500 will be described. The first transmission / reception unit 552, the second transmission / reception unit 554, the reception signal strength measurement unit 556, the connection information acquisition unit 560, the connection processing unit 562, the job request unit 564, and the storage / reading processing unit 566 are shown in FIG. The functions of each part of the wireless communication terminal 200 can be applied.

The tilt detection unit 572 of the wireless communication terminal 500 is realized by a command from the sensor 212 and the CPU 202 shown in FIG. The tilt detection unit 572 detects the tilt such as the angle of the wireless communication terminal 500 based on the measurement information such as the acceleration measured by the sensor 212.

FIG. 11 shows an example of acceleration measured by the wireless communication terminal 500. When an acceleration sensor is applied to the sensor 212, the acceleration is measured when an object is moved by the sensor 212. For example, the longitudinal direction of the LCD 214 of the wireless communication terminal 500 is the Y-axis, the left-right direction of the LCD 214 is the X-axis, and the direction perpendicular to the plane consisting of the X-axis and the Y-axis is the Z-axis. In this case, the wireless communication terminal 500 can obtain the acceleration in the left-right direction of the wireless communication terminal 500 by detecting the acceleration in the X-axis direction, and the wireless communication terminal 500 moves up and down by detecting the acceleration in the Y-axis direction. The acceleration in the direction can be obtained. Further, the wireless communication terminal 500 can obtain the acceleration in the front-back direction of the wireless communication terminal 500 by detecting the acceleration in the Z-axis direction. The tilt detection unit 572 determines the tilt of the wireless communication terminal 500 or the like by determining whether or not the acceleration measured by the sensor 212 has converged within a certain range.

FIG. 12 shows an example of the inclination of the wireless communication terminal 500, and shows a case where the wireless communication terminal 500 is inclined by 45 degrees from the horizontal direction. In this case, the tilt detection unit 572 detects that the acceleration of the wireless communication terminal 500 in the Y-axis direction is sin 45 °. When the tilt detection unit 572 can detect that the tilt of the wireless communication terminal 500 falls within a predetermined range, the tilt detection unit 572 notifies the connection target identification unit 558 of that fact. Here, the predetermined range is preset based on the inclination of the operation unit 122 of the image processing device 100. For example, when connecting the wireless communication terminal 500 to the image processing device 100, it is assumed that the user often holds the wireless communication terminal 500 parallel to the display screen of the touch panel 172 of the operation unit 122. When the wireless communication terminal 500 and the display screen of the touch panel 172 are parallel to each other, the inclinations of the two are equal. Therefore, the tilt detection unit 572 determines whether or not the tilt of the wireless communication terminal 500 is within a predetermined range from the tilt of the display screen of the touch panel 172.

The value of the inclination of the operation unit 122 of the image processing device 100 (the inclination of the display screen of the touch panel 172) is stored in advance in the storage unit 568 by, for example, the wireless communication terminal 500.

The connection target identification unit 558 of the wireless communication terminal 500 is realized by a command from the CPU 202 and a program for the wireless communication terminal stored in the HDD 208. The connection target identification unit 558 causes the storage / reading processing unit 566 to read the reception signal strength management table of the reception signal strength management DB 570 of the storage unit 568. Further, the connection target identification unit 558 is based on the reception signal strength of the device information disclosure packet stored in the reception signal strength management table and whether or not it is detected that the inclination of the wireless communication terminal 500 falls within a predetermined range. To specify the image processing device to be connected. Here, the predetermined range is preset according to the shape of the image processing device 100, and is stored in, for example, the storage unit 568.

Here, a case where the connection target is specified based on whether or not the average value μ of the received signal strength of the device information disclosure packet exceeds the threshold value Rs will be examined. Even if the connection target is specified based on whether the average value μ exceeds a certain threshold Rs and the standard deviation σ is within a certain range based on the standard deviation σ in addition to the average value μ. good.

FIG. 13 shows an example (No. 2) of the time change of the received signal strength of the device information disclosure packet received by the wireless communication terminal 200. In FIG. 13, the horizontal axis is time (t) and the vertical axis is the received signal strength (RSSI) of the device information disclosure packet. As shown in FIG. 13, depending on the antenna characteristics of the wireless communication terminal 200, the received signal strength of the device information disclosure packet transmitted by the image processing device 100 may be accidentally measured as a value larger than the threshold value Rs. In this case, since the wireless communication terminal 200 exceeds a certain threshold value Rs, which is the average value μ of the received signal strength of the device information disclosure packet, the wireless communication terminal 200 transmits a connection information request to the image processing device and is transmitted by the image processing device. Connection processing may be performed based on the connection information. There is no problem if this connection process is the image processing device intended by the user, but it is a problem if it is not the user's intention such as leaving the wireless communication terminal in a state where it can be connected to the image processing device. be.

FIG. 14 shows an example (No. 3) of the time change of the received signal strength of the device information disclosure packet received by the wireless communication terminal 200. In FIG. 14, the horizontal axis is time (t) and the vertical axis is the received signal strength (RSSI) of the device information disclosure packet. In FIG. 14, the received signal strength of the device information disclosure packet transmitted by the two image processing devices of the first image processing device and the second image processing device is measured. Of the first image processing device and the second image processing device, the first image processing device is the image processing device in front of the user and is desired to be connected. However, the received signal strength of the device information disclosure packet transmitted by the second image processing device may be accidentally measured as a value larger than the threshold value Rs. In this case, since the wireless communication terminal exceeds a certain threshold value Rs [dB], which is the average value μ [dB] of the received signal strength, the connection information request is transmitted to the second image processing device, and the image processing device transmits the connection information request. Connection processing may be performed based on the transmitted connection information.

As described above, in the wireless communication terminal 500 according to the present embodiment, in addition to the received signal strength of the device information disclosure packet, the inclination of the wireless communication terminal 500 is determined from the inclination of the display screen of the operation unit 122 of the image processing device 100. The connection target is specified based on whether or not it is within the range of. As a result, the wireless communication terminal 500 can reduce the connection with the image processing device not intended by the user.

<Operation of image processing system>
FIG. 15 mainly shows the operation of the wireless communication terminal 500 of the image processing system according to the present embodiment. Steps S1502-S1506 can apply steps S902-S906 of FIG.

In step S1508, when there is an image processing device in which the average value μ of the received signal strength exceeds the threshold value Rs, the connection target identification unit 558 of the wireless communication terminal 500 determines the inclination of the wireless communication terminal 500 by the inclination detection unit 572. Determine if it is detected to be in range. If it is not detected that the inclination of the wireless communication terminal 500 falls within a predetermined range, the process returns to step S1502.

In step S1510, when the tilt detection unit 572 detects that the tilt of the wireless communication terminal 500 falls within a predetermined range, the connection target identification unit 558 of the wireless communication terminal 500 sets the image processing device as the connection target. Set.

In step S1512, the connection information acquisition unit 560 of the wireless communication terminal 500 requests the connection information from the image processing device set as the connection target. When the connection processing unit 562 of the wireless communication terminal 500 acquires the connection information transmitted by the image processing device set as the connection target, the connection processing unit 562 uses the connection information to perform connection processing with the image processing device.

After the connection process is performed in step S1512, the job request unit 564 of the wireless communication terminal 500 transmits a job such as printing or scanning requested by the user from the second transmission / reception unit 554 to the connected image processing device. ..

In the flowchart shown in FIG. 15, the processing of steps S1502-S1506 and S1510 may be performed after the processing of step S1508.

In step S1506 of FIG. 15, the connection target identification unit 558 collectively determines whether or not there is an image processing device in which the average value μ of the received signal strength of the device information disclosure packet exceeds the threshold value Rs. This determination may be made individually for each image processing device. For example, the connection target identification unit 558 individually calculates the average value of the received signal strength of the image forming apparatus each time the device information disclosure packet is received from each image forming apparatus, and the calculated average value μ exceeds the threshold value Rs. If so, the process of step S1508 may be executed.

And send.

For example, in the case of the image processing device 100 in which the angle of the operation unit 122 is fixed, the device information disclosure packet creation unit 406 stores the inclination value of the operation unit 122 in the storage unit 416 in advance, and the stored operation. The value of the inclination of unit 122 is included in the device information disclosure packet and transmitted.

Further, if the image processing device 100 can change the inclination of the operation unit 122, the image processing device 100 has a value of the inclination of the operation unit 122 based on the acceleration measured by the sensor 170, similarly to the wireless communication terminal 500.
