Referring to FIG. 3, a method of displaying a web page including the second image 160 through the display unit 230 through the user terminal 230 will be described in more detail.

In operation 310, the user terminal 100 may attempt to access a web page including the first image 150. For example, a user of the user terminal 100 may attempt to access a web page including the first image 150 through a predetermined connection application installed in the user terminal 100. The connection application may be, for example, a web browser application or an application including a web engine for displaying a web page in a window area. Access to the web page may be made by inputting the address of the web page through the user terminal 100 or by selecting a link to the web page.

In operation 320, the controller 220 may hook a URL of the first image 150 included in the web page to which the user terminal 100 is connected. For example, the controller 220 may hook the URL of the first image 150 included in the web page using a web engine included in a predetermined connection application. Hooking the URL of the first image 150 may be to intercept the URL of the first image 150. For example, the URL of the first image 150 included in the HTML code of the web page may be hooked.

In operation 330, through the communication unit 210, the controller 220 may request the second image 160 from the image conversion server 120 based on the URL of the hooked first image 150. For example, the controller 220 may request the second image 160 from the image conversion server 120 based on the URL of the hooked first image 150 using a web engine of a predetermined connection application. The request of the second image 160 is made by using the URL of the hooked first image 150 and a predetermined quality value. The second image 160 requests an image whose quality is changed to have a predetermined quality value as the second image 160. It may be.

In this case, the predetermined quality value may be preset by the user terminal 100. For example, the user of the user terminal 100 may set a predetermined quality value through a user interface provided through the interface provider 225. For example, the predetermined quality value 50 may be such that the size of the second image 160 is 50% compared to the first image 150.

In operation 340, the control unit 220 may receive the second image 160 from the image conversion server 120 through the communication unit 210, and the first image may be received as the received second image 160. By replacing 150, the second image 160 can be provided as a response to the attempted connection at step 310. In other words, in response to the attempt to connect in step 310, a web page on which the first image 150 is replaced by the second image 160 received from the image conversion server 120 is displayed on the display 230. Can be. The second image 160 may be an image in which the quality (or size) of the first image 150 is changed to a predetermined quality value included in the operation 330.

In steps 310 to 340, the user terminal 100 may optimize data usage by displaying images in loading and providing a web page.

As described above, the description of the technical features described above with reference to FIGS. 1 and 2 may be applied to FIG. 3 as it is, and thus redundant descriptions thereof will be omitted.

4 illustrates a method of determining a predetermined quality value for changing a quality of an original image, according to an example.

An additional method of determining the "predetermined quality value" described in step 330 described above with reference to FIG. 3 will be described in more detail.

The predetermined quality value may be automatically determined by performing steps 410 to 430 in addition to being preset by the user terminal 110.

In operation 410, the user terminal 100 may establish a connection with an external server. The external server may be a server external to the user terminal 100 and may be, for example, the image conversion server 120 described above. Alternatively, the server may be any server capable of transmitting / receiving data with the other user terminal 100. The user terminal 100 may establish a connection with such an external server periodically (for example, every predetermined time).

In operation 420, the user terminal 100 may transmit a test packet to an external server or receive a test packet from an external server. The test packet may be a packet having a unit size. The unit size may be small so as not to significantly affect the data usage of the user terminal 100.

In step 430, at the user terminal 110 or the external server side, a predetermined quality value may be determined based on the difference between the transmission time and the reception time of the test packet. When the predetermined quality value is determined at the external server side, when the user terminal 100 requests the second image 160 from the image conversion server 120, the predetermined quality value is separately transmitted to the image conversion server 120. It may not be.

The predetermined quality value may be set to a lower value as the difference between the transmission time and the reception time of the test packet increases. In other words, as the difference between the transmission time and the reception time of the test packet increases, it may be determined that the communication state between the user terminal 100 and the external server is not smooth, and therefore, the predetermined quality value may be set to a lower value. have.

Even if the user does not set a predetermined quality value through the user terminal 100 by the steps 410 to 430, the web page including the second image 160 having the optimal quality value is displayed on the display unit 230. Can be displayed through.

As described above, the description of the technical features described above with reference to FIGS. 1 to 3 may be applied as it is to FIG. 4, and thus redundant descriptions thereof will be omitted.

5 is a flowchart illustrating a method of providing content including an image whose quality is changed according to a communication state of a user terminal according to an example.

Steps 320 to 340 described above with reference to FIG. 3 may be determined according to a communication state of the user terminal. Reference is made to steps 510 to 530 in more detail.

In operation 510, the controller 220 may identify a communication state of the user terminal 100. For example, the controller 220 may identify whether the user terminal 100 is communicating using a cellular network.

When the user terminal 100 is identified as communicating using a cellular network, the above-described steps 320 to 340 may be performed. That is, as the above-described steps 320 to 340 are performed, a web page including the second image 160 having an optimal quality is provided to the user terminal 100, thereby using cellular data of the user terminal 100. Can be reduced.

If it is determined that the user terminal 100 is not communicating using the cellular network, in step 520, the controller 220 sets the use of the function of providing the second image 160 of the embodiment to the user terminal 100. (Ie, setting of use of the quality change image providing method) can be determined to be ON.

That is, when the usage setting of the data saver function corresponding to the usage setting of the second image 160 providing function of the embodiment is turned ON, the user terminal 100 is connected to the Wi-Fi in step 510. Even when identified as communicating via e), steps 320 to 340 may be performed.

The use setting of the function of providing the second image 160 is turned ON, so that the steps 320 to 340 are set to be performed.

If the usage setting of the second image 160 providing function is not turned ON, steps 320 to 340 may not be performed (step 530). That is, in response to a request for access to a web page from the user terminal 100, a web page including the original first image 150 is displayed on the display unit 230.

As described above with reference to FIG. 5, the data saver function may be executed according to a communication state of the user terminal 100 and a user setting for the user terminal 100.

As described above, the description of the technical features described above with reference to FIGS. 1 to 4 may be applied as it is to FIG.

FIG. 6 is a flowchart illustrating a method of calculating and providing data usage saved by providing an image whose quality is changed according to an example.

In operation 610, the controller 220 may provide the user terminal 100 with the second image 160 instead of the first image 150 according to the operation 340 described above with reference to FIG. 3. Data usage saved in the user terminal 100 may be calculated. For example, the controller 220 may accumulate the data usage saved for a predetermined period (eg, one day, one week, one month). Alternatively, or additionally, the controller 220 may accumulate the saved data usage for the entire period (from the time when the user terminal 100 starts driving or when the data saver function is first used).

In operation 620, the controller 220 may provide information about the calculated saving data usage. For example, the controller 220 may display information about the saved data usage calculated by step 610 through the user interface.

Through steps 610 and 620, the user can check the data usage saved by using the data saver function.

As described above, the description of the technical features described above with reference to FIGS. 1 to 5 may be applied to FIG. 6 as it is, and thus redundant descriptions thereof will be omitted.
