  By the way, the storage function of the website screen being displayed on the display unit has been implemented in association with the browser function. However, in the case where the screen of the website is usually stored, each element constituting the website is saved. Generally, a method of saving in a file format (for example, HTML file, JPEG file, MIDI file, etc.) is adopted. Such storage for each file requires a large memory capacity.

  However, in mobile communication terminal devices that are strongly demanded for miniaturization, the amount of memory mounted is limited, and a sufficient memory capacity cannot be secured for storing a normal website screen. For this reason, the number of website screens that can be saved is limited depending on the type of website screen that the user desires, which may impair the convenience of the user.

  An object of this invention is to provide the web screen preservation | save method and mobile communication terminal device which can preserve | save a website screen rationally, ensuring the convenience of a user.

From a first aspect, the present invention is a web screen storage method used for storing a website screen in a mobile communication terminal device, wherein the website screen is at least partially displayed on a display unit. When an instruction to save the information on the displayed website screen is issued, the storage capacity required when the information on the entire screen of the displayed website screen is saved in the normal format that is the format received from the web server. A size determination step for determining whether or not a storable capacity condition is satisfied; and if the result of determination in the size determination step is negative, all of the storage formats prepared in advance upon storage of the image data of the screen, determining whether the storage capacity satisfies at least one of the first applicable can save format is present That a first storage format determination step; if the first judgment in the storage format determination process results were those affirmative, among the first applicable storage format, the data compression rate is the lowest optimal A full-screen saving step of saving the full-screen image data in association with an identifier indicating a location of the website on the network in a saving format ; a result of the determination in the first saving format determining step is negative If it is, the image data of the area currently displayed on the screen among the plurality of storage formats prepared in advance is at least one second that can satisfy the storage capacity requirement. A second storage format determination step for determining whether or not an applicable storage format exists; and if the determination result in the second storage format determination step is affirmative, the second storage format determination step Display that saves the image data of the area currently displayed on the screen in association with an identifier indicating the location of the website on the network in the optimum storage format having the lowest data compression rate among the available storage formats A web screen storage method comprising: a size storage step;

  In this web screen saving method, when a screen saving instruction is given by a user input operation or the like while at least a part of the website screen is displayed on the display unit, first, it is a display target in the size determination step. The storage capacity required when the entire screen, which is the entire website screen, is stored in a normal format that is stored as a file for each element constituting the website screen. Subsequently, it is determined whether the storage capacity satisfies a predetermined storable capacity condition.

If the result of the determination in the size determination step is negative, in the first storage format determination step, the image data of the full screen is stored in the plurality of storage formats prepared in advance. It is determined whether there is at least one first applicable storage format that can satisfy the storage capacity requirement. Here, the plurality of storage formats prepared in advance are storage formats based on at least one compression level defined for at least one image format such as JPEG (Joint Photograph Experts Group) or PNG (Portable Network Graphic). Say.

That is, in the first storage format determination step, it is determined whether or not the entire screen can be stored as image data so as to satisfy the storage capacity requirement by at least one of the plurality of storage formats. If the result of this determination is affirmative for at least one first applicable storage format, in the full-screen storage process, the best data compression rate is the lowest among the first applicable storage formats. In the storage format, the image data of the entire screen is stored in association with an identifier indicating the location of the website on the network.

  Here, the reason why the data is stored in the optimum storage format with the lowest data compression ratio is to store the data in a format that has the best image reproducibility among the formats that satisfy the storage capacity requirement. The reason why the website is stored in association with the identifier indicating the network position is to use the stored image data as an index and to access the website again using the identifier.

Therefore, according to the web screen saving method of the present invention, it is possible to rationally save the image data of the entire screen, which is the entire website screen to be displayed .

In the web screen storage method of the present invention, when the result of the determination in the first storage format determination step is negative, that is, depending on a plurality of storage formats prepared in advance, the storable capacity condition is satisfied. When it is determined that it is impossible to save the entire screen, an image of the area currently displayed on the screen among the plurality of storage formats prepared in advance in the second storage format determination step. It is determined whether there is at least one second applicable storage format that can satisfy the storable capacity condition of the data. If the result of determination in the second storage format determination step is affirmative, a display size storage step is executed. In this display size saving step, the area currently displayed on the screen is saved as image data in an optimum saving format with the lowest data compression rate that satisfies the storable capacity condition. At this time, similarly to the case of the full screen saving process, the website is stored in association with the identifier indicating the position of the website on the network.

  In the web screen storage method of the present invention, the storable capacity condition can be a size equal to or smaller than a predetermined maximum storable size. In this case, the minimum number of web screens that can be stored in the storage area for web screen storage is guaranteed.

  In the web screen saving method of the present invention, the storable capacity condition can be set to a size equal to or less than the amount of memory remaining in the web screen saving area. In this case, even if the free storage area for saving the web screen has become small, the web screen can be saved with as much screen reproducibility as possible.

The present invention is, to a second aspect, a display unit for displaying an image; and storage means including a web screen save area reserved for storing information website screen being displayed on the display unit; the A format in which information on the entire screen of the displayed website screen is received from the web server when an instruction to save the information on the displayed website screen, which is at least a part of the website screen being displayed on the display unit, is given. Size determination means for determining whether or not the storage capacity required when saving in a normal format satisfies a storable capacity condition; and when the result of determination by the size determination means is negative, in the plurality of storage format, which is prepared in advance, the time of storage of the image data of the entire screen, the storage capacity of at least one of the first optimal can satisfy the condition Possible a first storage format determining means for determining whether storage format is present; the by when the result of judgment is the affirmative the first storage format determining unit, the first applicable save format among, the data compression rate is lowest optimal storage format, the image data of the entire screen, a full screen storing means for storing in association with an identifier indicating a network location of the web site; the first storage format If the result of the determination by the determination means is negative, the image data of the area currently displayed on the screen among the plurality of storage formats prepared in advance is stored in the storage capacity condition Second storage format determination means for determining whether or not there is at least one second applicable storage format that can satisfy the condition; a result of determination by the second storage format determination means is affirmative If it is, the image data of the area currently displayed on the screen in the optimum storage format having the lowest data compression rate among the second applicable storage formats is transferred to the network of the website. A display size storing means for storing in association with an identifier indicating a position .

In this mobile communication terminal device, when an instruction to save the screen is given while at least a part of the website screen is displayed on the display unit, the size determination means displays the entire screen that is the entire website screen to be displayed. A determination is made as to whether or not the storage capacity required when saving in a normal format that saves as a file for each element constituting the website screen satisfies the storable capacity condition. If the result of this determination is negative, the entire screen cannot be stored in the file format for each element, so the first storage format determination means is prepared in advance in the mobile communication terminal device. Whether or not there is at least one first applicable storage format that can satisfy the storable capacity condition when storing the image data for the entire screen among the plurality of storage formats. judge.

If the result of the determination by the first storage format determination means is affirmative, it means that image data can be stored in the at least one first applicable storage format. Therefore, from the viewpoint of the reproducibility of the screen, the full screen storage means selects the optimum storage format with the lowest data compression rate among the applicable first applicable storage formats. The full screen storage means stores the image data of the full screen of the website in an optimum storage format in association with an identifier indicating the location of the website on the network.

That is, the mobile communication terminal device of the present invention can store the image data of the entire screen, which is the entire website screen to be displayed , using the web screen storage method of the present invention described above. Therefore, according to the mobile communication terminal device of the present invention, it is possible to rationally store the website screen.

In the mobile communication terminal of the present invention, when the result of the determination by the first storage format determination means is negative, that is, when the entire screen cannot be stored, the second storage format determination means Whether there is at least one second applicable storage format that can satisfy the storable capacity condition of the image data in the area currently displayed on the screen among the plurality of storage formats prepared in advance. Determine whether or not. If the result of the determination by the second storage format determination means is affirmative, the display size storage means does not target the entire screen, but targets the area currently displayed on the screen at the timing when the screen storage is selected. It will be saved as image data. At this time, the display size storage means selects the storage format having the lowest data compression rate that satisfies the storable capacity condition, that is, the best reproducibility. Then, the display size storage unit stores the displayed area as a target in association with the identifier indicating the position of the website on the network.

  In the mobile communication terminal device of the present invention, the storable capacity condition can be set to a size not larger than a predetermined maximum storable size. In this case, when the screen is saved, each image data is saved in a size equal to or smaller than a certain value. For this reason, the minimum number of web screens that can be saved in the storage area for web screen saving is guaranteed.

  In the mobile communication terminal device of the present invention, the storable capacity condition can be set to a size equal to or less than the amount of memory remaining in the web screen storage area. In this case, even when the free storage area for saving the web screen has been reduced, the web screen can be saved with as much screen reproducibility as possible.

  Therefore, according to the web screen storage method of the present invention, there is an effect that rational web screen storage can be performed in the mobile communication terminal device.

  In addition, according to the mobile communication terminal device of the present invention, there is an effect that rational web screen storage can be performed.

Save in the save area 25.

<Operation>
Next, the operation of storing the web screen in the mobile communication terminal apparatus 10 configured as described above will be mainly described.

  First, when the web browser 31 is activated and it is detected that the user has selected to save the web screen being browsed by an input operation from the operation unit 12 or the like while browsing the website, The storage control unit 32 is activated.

  When the screen storage control unit 32 is activated, as shown in FIG. 4, first, in step S11, the total size determination unit 33 displays information related to the website screen in the same format as that transmitted from the web server. The total size of all files in the case of saving in a normal format composed of HTML files, individual image files, and the like is calculated. Subsequently, in step S12, the total size determination unit 33 determines whether the total size is equal to or smaller than a predetermined size. Here, the predetermined size is the remaining amount of memory in the screen storage area 25. If the result of the determination is affirmative, it means that there is an area where the total size can be stored. Therefore, the total size determination unit 33 reports the fact to the normal storage unit 36, and the processing is step. Proceed to S13.

  In step S <b> 13, the normal storage unit 36 that has received a report that the determination result by the total size determination unit 33 is affirmative stores the information on the website screen in the screen storage area 25 in the normal format. When the storage is completed, the process ends.

  If the result of the determination in the above step S12 is negative, it means that the size is too large to be stored in the format for each file, so that the total size determination unit 33 indicates that the storage determination unit 34, the process proceeds to step S14. In step S14, compression storage processing is performed to store the entire screen, which is the entire screen that can be displayed on the website, as an image.

  In the compression storage process, as shown in FIG. 5, first, in step S21, the compression determination unit 34 performs post-compression for all compression levels that can be selected in the file format employed when storing the entire screen as an image. It is determined whether or not the size (compressed size) has been calculated. Here, the “adopted file format” is, for example, a JPEG format, a GIF format, or the like, and is set in advance. Further, as the “compression level”, a plurality of levels are prepared in advance including the case where compression is not performed.

  If the determination result in step S21 is negative, the process proceeds to step S22. In step S22, the storage determination unit 34 calculates the compressed data size of the image data of the entire screen according to a selectable compression level.

  Subsequently, in step S23, the storage determination unit 34 determines whether or not the compressed data size calculated in step S22 is equal to or smaller than a predetermined size, that is, the remaining amount of memory available for storing image data in the screen storage area 25. Determine whether. If the result of the determination is negative, the process returns to step S21 in order to determine that the next compression level is applied. And the process of step S21-S23 is repeated until the result of a positive determination is obtained in step S21 or step S23.

  Note that in the repetition of the processing of steps S21 to S23, the compression size in step S22 is calculated in the order of the degree of compression.

  If the result of the determination in step S23 is affirmative, it means that it is possible to save the compressed image, so the compression format for which the latest compression size has been calculated is selected as the saving format. Then, the process proceeds to step S24.

  In step S24, the storage determination unit 34 first outputs to the display unit 13 an inquiry to the user as to whether or not to save the entire screen as an image compressed in the selected storage format. When saving is selected by the input operation of the user who has seen this display, the saving determination unit 34 reports the fact and the selected saving format to the full-screen saving unit 37. Then, the process proceeds to step S25.

  In step S <b> 25, the full screen storage unit 37 performs a process of compressing the image data of the full screen according to the selected storage format and storing it in the screen storage area 25. At the time of the storage, the image is stored in the screen storage area 25 in association with the URL of the website. When the storage is completed, the process of step S14 ends. As a result, the compression storage process ends (see FIG. 4).

  On the other hand, in step S24, when it is selected not to save by the user's input operation, the process of step S14 is finished as it is, and the compression saving process is finished.

  If the result of the determination in step S21 described above is affirmative, the process proceeds to step S26. In this step S26, a display size storing process for storing image data in a display size that is the size currently displayed on the display unit 13 is performed.

  In the display size saving process, as shown in FIG. 6, first, in step S31, the save determination unit 34 selects all the compression levels that can be selected in the file format employed when saving the display size screen as an image. Then, it is determined whether or not the size after compression (compressed size) has been calculated. If the result of the determination is negative, the process proceeds to step S32. In step S32, the storage determination unit 34 calculates the data size after compression of the image data on the display size screen according to a selectable compression level.

  Subsequently, in step S33, the storage determining unit 34 determines whether or not the compressed data size calculated in step S32 is equal to or smaller than a predetermined size, that is, a remaining memory capacity available for storing image data in the screen storage area 25. Determine whether. If the result of the determination is negative, the process returns to step S31 in order to determine that the next compression level is applied. Then, the processes in steps S31 to S33 are repeated until a positive determination result is obtained in step S31 or step S33.

  In the repetition of the processes of steps S31 to S33, the data size after compression in step S33 is calculated in the order of the lower degree of compression, as in the case of the repetition of the processes of steps S21 to S23 described above.

  If the determination result in step S33 is affirmative, the process proceeds to step S34. In step S34, the storage determination unit 34 first outputs to the display unit 13 a question as to whether or not to save the display size screen as an image compressed in the selected storage format. To do. When saving is selected by the input operation of the user who has seen this display, the saving determination unit 34 reports the fact and the selected saving format to the display size saving unit 38. Then, the process proceeds to step S35.

  In step S35, the display size storage unit 38 performs a process of compressing the image data of the display size screen according to the selected storage format and storing it in the screen storage area 25. At the time of the storage, the image is stored in the screen storage area 25 in association with the URL of the website. When the storage is completed, the process of step S26 ends. As a result, the process of step S14 ends, and the compression storage process ends (see FIGS. 4 and 5).

  On the other hand, if it is selected not to save in step S34 by the user's input operation, the process of step S26 is terminated as it is. As a result, the process of step S14 ends, and the compression storage process ends.

  If the result of the determination in step S31 described above is affirmative, it is determined that storage has been determined for all the compression levels of the predetermined file format, and still not less than the remaining amount of memory in the screen storage area 25. is there. For this reason, when the result of the determination in step S31 is affirmative, the process proceeds to step S36, and “not storable” is displayed on the display unit 13. And the process of step S26 is complete | finished. As a result, the process of step S14 ends, and the compression storage process ends.

  As described above, the mobile communication terminal device of the present invention includes the display unit 13 and the image storage area 25 as a premise. When a screen save command is given while a website is being displayed, the entire screen, which is the entire website screen to be displayed, is saved as a file for each element constituting the website screen. The total size determining unit 33 determines whether or not the storage capacity required in the case of storing satisfies the storable capacity condition.

  If the result of determination by the total size determination unit 33 is negative, the image data is stored for the entire screen in a plurality of storage formats prepared in advance in the mobile communication terminal device. At this time, the storage determination unit 34 further determines whether or not there is at least one applicable storage format that can satisfy the storage capacity requirement.

  If the result of the determination by the storage determination unit 34 is affirmative, the optimum storage format with the lowest data compression rate is selected from the applicable applicable storage formats. Therefore, the full screen storage unit 37 stores the image data in the storage format in association with the identifier indicating the location of the website on the network.

  When the result of the determination in the storage determination unit 34 is negative and the entire screen cannot be stored, the target is not the entire screen but the area currently displayed on the screen at the timing when the screen storage is selected. As image data. Also at this time, the screen size storage means selects the storage format with the lowest data compression rate that satisfies the storable capacity condition. Subsequently, the display size storage unit 38 stores the displayed area as a target in association with the identifier indicating the position of the website on the network.

Therefore, according to the present embodiment, it is possible to provide a web screen saving method and a mobile communication terminal device that can rationally save a website screen while ensuring user convenience.
