Description

  The present invention relates to an information terminal device, and more particularly to a small information terminal such as a mobile phone or a mobile information terminal having a function of acquiring a document or an image from a server through the Internet.

In recent years, with the advancement of advanced information technology, it has become possible for a user to immediately acquire various information through the Internet simply by inputting an access destination address to a personal computer. The information to be acquired is hypertext described in HTML (HyperTextMarkupLanguage) or the like, mail described in MIME (MultipurposeInternetMailExtensions), or the like. By using a hypertext display device equipped with an application called a browser or a mail display device equipped with an application called a mailer, the user requests the server to obtain information or displays the information obtained from the server on the screen. You can do it.
As such browsers, “Netscape Navigator”, “Internet Explorer”, and the like are widely used. In these browsers, image information (images) can be acquired from a server through the Internet and used as a background (background screen) or a screen saver.

  Recently, with the miniaturization of devices, browsers and mailers have also been installed in small information terminal devices such as mobile phones and portable information terminals. In the small information terminal device, as in the case of a personal computer, there is a demand for acquiring an image from a server and using it as a background screen or the like.

  In addition, in the case of a personal computer, when acquiring an image from the server and using it as a background screen, a plurality of images are accumulated and stored, and one of the images is selected and used as a background screen. can do. Therefore, in a small information terminal device, when an image is acquired from a server and used as a background screen, it is expected that a request for selecting an image is generated as in the case of a personal computer.

(First issue)
In the case of a small information terminal device, the size of the display screen is smaller than that of a personal computer, and the size of the display screen varies depending on the model. Therefore, in order to use the image acquired from the server as the background screen, it is necessary to convert the size of the image so as to fit the display screen.
However, since existing browsers are designed on the assumption that they will be used on a personal computer with a fixed screen size, they do not have the function of converting the size of an image and setting it as a background screen.
Therefore, conventionally, in a small portable information terminal, an image acquired from a server cannot be used as a background screen.

  Note that the image acquired from the server can be converted into a size once using an image processing tool or the like and set on the background screen. However, this method can only be performed by an information terminal device that has a relatively large storage capacity and can be easily input by a pointing device or the like. In particular, in the case of a mobile phone, the storage capacity is greatly limited, and the input operation is extremely complicated because of the use of numeric keys and buttons. Therefore, a method using an image processing tool is not practical.

Temporarily store as a display image.

  In step S116, the display unit 413 uses the image stored in the display image temporary storage unit 412 (that is, the image selected in step S112 or the image obtained by size conversion in step S114) as a background screen. Displayed in the display area 504.

In step S117, the input determination unit 402 determines whether the instruction received by the input unit 401 is an image display stop instruction. If the determination result in step S117 is affirmative, the display unit 413 stops the image display, and if negative, the above steps S101 to S117 are executed again.
The above is the outline of the operation of the mobile device.

Next, the main steps among the steps S101 to S117 will be described in detail.
The effective display area size setting / storage process in steps S103 and S104 is performed as follows. In the effective display area size setting unit 403, several sizes that can be set as effective display area sizes are prepared in advance. When the user presses a specific button of the input unit 401, the effective display area size setting unit 403 Select one of these sizes and set it as the effective display area size. The size set by the effective display area size setting unit 403 is stored by the effective display area size storage unit 404.
In the example of FIG. 5, either (80 × 90) or (80 × 70) is set by the effective display area size setting unit 403, and the set size is stored in the effective display area size storage unit 404. The

  Alternatively, the user may specify an arbitrary size by operating the keyboard of the input unit 401, and the effective display area size setting unit 403 may set the specified size as the effective display area size.

  The image conversion form setting / storing process in steps S106 and S107 is performed as follows. That is, several image conversion forms are prepared in advance in the image conversion form setting unit, and when the user presses a specific button of the input unit 401, the image conversion form setting unit selects one of these forms. Select and set the form as an image size conversion form. The form set by the image size conversion form setting unit 405 is stored in the image size conversion form storage unit 406.

The image size conversion forms prepared in the image conversion form setting unit are the first to third image size conversion forms.
7 to 9 are diagrams visually showing the first to third image size conversion forms.
As shown in FIG. 7, the first image size conversion form is a form that reduces the image at the same aspect ratio (that is, reduces the resolution by thinning out pixels at a certain ratio). If this first form is used, the converted image has a size that does not change its aspect ratio (that is, the shape is flattened) and fits within the effective display area.

As shown in FIG. 8, the second image size conversion form is a form that converts the image size to a smaller size by cutting out a part of the image. If this second form is used, the portion of the converted image that extends beyond the effective display area is deleted, but the resolution does not drop.
As shown in FIG. 9, the third image size conversion form is a conversion form that reduces an image at an individual aspect ratio. If this third form is used, the converted image will be flat enough to fit within the effective display area without excess or deficiency.

  In the image storage / storage process in step S110, the image storage / storage unit 408 sequentially assigns, for example, serial numbers (0, 1, 2,...) As identifiers (ID) to the images to be stored.

The image selection process in step S112 is performed as follows. When only one image is stored and stored in the image storage and storage unit 408 in step S110, the image selection unit 409 selects the image.
When there are a plurality of images stored and stored in the image storage and storage unit 408 in step S110, the image selection unit 409 refers to the identifier given by the image storage and storage unit 408 in step S110, and selects any of the plurality of images. Or select one.
Here, an example of the simplest selection method is given. That is, when the image storage unit 408 stores, for example, three images (ID = 1 to 3) in step S110, the image selection unit 409 selects the first image (ID = 1).

The protrusion determination process in step S113 is performed as follows.
The protrusion determination unit 410 first detects the size of the image selected by the image selection unit 409 in step S112. Note that data indicating the size is attached to the images provided from the WWW servers 18 and 19, and the size of the image can be detected based on the data.
Next, the protrusion determination unit 410 compares the size of the image with the size of the effective display area in each of the horizontal direction and the vertical direction, and determines whether or not the protrusion occurs.

The image size conversion process in step S114 is performed as follows.

The image size conversion unit 411 calculates the expansion / contraction ratio so that the horizontal size of the converted image matches the horizontal size of the effective display area, and reduces the image by the expansion / contraction ratio in both the vertical and horizontal directions.

  An example of the process (1) is shown in FIG. In this example, the protrusion determination unit 410 compares the horizontal size 80 of the effective display area with the horizontal size 120 of the image, and determines that the horizontal protrusion occurs. Therefore, the image size conversion unit 411 calculates the expansion / contraction ratio (2/3) by dividing 80 by 120. Then, based on the first form, the image is reduced by (2/3) times in both the vertical and horizontal directions.

(2) If the form stored in the image size conversion form storage unit 406 in step S107 is the first form, and the protrusion determination unit 410 determines in the protrusion determination process in step S113 that vertical protrusion occurs. The image size conversion unit 411 calculates an expansion / contraction ratio such that the vertical size of the converted image matches the vertical size of the effective display area, and reduces the image by the expansion / contraction ratio in both the vertical and horizontal directions.

In this example, the protrusion determination unit 410 compares the vertical size 90 of the effective display area with the vertical size 150 of the image, and determines that the vertical protrusion occurs. Therefore, the image size conversion unit 411 calculates the expansion / contraction ratio (3/5) by dividing 90 by 150. Then, based on the first form, the image is reduced by (3/5) times in both the vertical and horizontal directions.

(3) The form stored in the image size conversion form storage unit 406 in step S107 is the first form, and the protrusion determination unit 410 determines in the protrusion determination process in step S113 that vertical and horizontal protrusions occur. In this case, the image size conversion unit 411 matches the expansion / contraction ratio so that the vertical size of the converted image matches the vertical size of the effective display area, and the horizontal size of the converted image matches the horizontal size of the effective display area. Such an expansion / contraction ratio is calculated, and the image is reduced in both the vertical and horizontal directions by the smaller expansion / contraction ratio of the two expansion ratios.

In this example, the protrusion determination unit 410 compares the horizontal size 80 of the effective display area with the horizontal size 120 of the image, and determines that the horizontal protrusion occurs. Further, the vertical size 90 of the effective display area is compared with the vertical size 150 of the image, and it is determined that the vertical protrusion occurs. Therefore, the image size conversion unit 411 calculates the expansion / contraction ratio (2/3) by dividing 80 by 120. Further, the expansion / contraction ratio (3/5) is calculated by dividing 90 by 150. Based on the first form, the image is reduced by (3/5) times in both the vertical and horizontal directions (because the latter is smaller in (2/3) and (3/5). Is).

  An example of the process (4) is shown in FIG. In this example, the protrusion determination unit 410 compares the horizontal size 80 of the effective display area with the horizontal size 120 of the image, and determines that the horizontal protrusion occurs. Therefore, the image size conversion unit 411 deletes the left end portion (corresponding to the horizontal size 20) and the right end portion (corresponding to the horizontal size 20) from the image based on the second form. Instead of deleting the left and right sides of the image equally, only the left end portion (equivalent to the horizontal size 40) may be deleted, or only the right end portion (equivalent to the horizontal size 40) may be deleted.

(5) If the form stored in the image size conversion form storage unit 406 in step S107 is the second form, and the protrusion determination unit 410 determines in the protrusion determination process in step S113 that vertical protrusion occurs.

In this example, the protrusion determination unit 410 compares the vertical size 90 of the effective display area with the vertical size 150 of the image, and determines that the vertical protrusion occurs. Therefore, the image size conversion unit 411 deletes the upper end portion (corresponding to the vertical size 30) and the lower end portion (corresponding to the vertical size 30) of the image based on the second form. Instead of deleting the top and bottom of the image equally, only the upper end portion (equivalent to the vertical size 60) may be deleted, or only the lower end portion (equivalent to the vertical size 60) may be deleted.

(6) The form stored in the image size conversion form storage unit 406 in step S107 is the second form, and the protrusion determination unit 410 determines in the protrusion determination process of step S113 that vertical and horizontal protrusions occur. In this case, the image size conversion unit 411 first deletes the left end portion and the right end portion of the image protruding from the effective display area, and then deletes the upper end portion and the lower end portion of the image protruding from the effective display area.

  An example of the process (6) is shown in FIG. In this example, the protrusion determination unit 410 compares the horizontal size 80 of the effective display area with the horizontal size 120 of the image, and determines that the horizontal protrusion occurs. Further, the vertical size 90 of the effective display area is compared with the vertical size 150 of the image, and it is determined that the vertical protrusion occurs. Therefore, based on the second form, the image size conversion unit 411 first deletes the left end portion (equivalent to the horizontal size 20) and the right end portion (equivalent to the horizontal size 20) of the image, and then the upper end portion (vertical size) of the image.

(7) If the form stored in the image size conversion form storage unit 406 in step S107 is the third form, and the protrusion determination unit 410 determines in the protrusion determination process in step S113 that lateral protrusion occurs. The image size conversion unit 411 calculates an expansion / contraction rate so that the horizontal size of the converted image matches the horizontal size of the effective display area, and reduces the image in the horizontal direction with the expansion / contraction rate.

  An example of the process (7) is shown in FIG. In this example, the protrusion determination unit 410 compares the horizontal size 80 of the effective display area with the horizontal size 120 of the image, and determines that the horizontal protrusion occurs. Therefore, the image size conversion unit 411 calculates the expansion / contraction ratio (2/3) by dividing 80 by 120.

Create an image list box that describes (hereinafter referred to as image information).

  As the image information described in the image list box, it is preferable to use an image storage location (such as “moon.gif” or “star.gif”). This is because the storage location of an image is associated with the image and often includes the name of the image, so that the user can immediately understand what image corresponds to the image storage location. In addition, the storage position of the image can be easily obtained by analyzing the HTML document (the HTML document should have been acquired from the WWW servers 18 and 19 prior to acquiring the image).

  The image selection unit 409 focuses on any one of a plurality of boxes constituting the image list box and moves the focus up and down (and / or left and right) according to the user's key operation. When a determination is input by a user's key operation in a state where a certain box is focused, the image selection unit 409 selects one image (or image information) described in the box. .

FIG. 14 is a flowchart showing details of the HTML document analysis processing in step S208 of FIG. Hereinafter, how the HTML document analysis 1007 analyzes an HTML document will be described with reference to FIGS. 13 and 14. FIG.

  14, the HTML document analysis 1007 first decomposes the HTML document stored and stored in the HTML storage / storage unit 1006 in step S207 of FIG. 12 into a plurality of elements (step S301), and then identifies (ID) each element. (Step S302). Here, the ID is a serial number starting from 0. Therefore, if the number of elements obtained by the decomposition in step S301 is N, ID = 0, 1, 2,..., (N−1) is assigned to each element.

  Next, the HTML document analysis 1007 sets an initial value (in this case, 0) to “k” indicating the identifier of the element to be analyzed (step S303). Next, the HTML document analysis 1007 determines whether or not the element “k” includes some information prepared in advance, and further, based on the determination result, the element “k” is prepared in advance. Which of the plurality of element types belongs is specified (step S304).

Next, the HTML document analysis 1007 notifies the HTML information storage and storage unit of the analysis result of step S304, that is, what element type the element “k” belongs to and what kind of information it has (step step). S305).
Next, the HTML document analysis 1007 increments “k” (step S306), and then determines whether “k” is greater than “N−1” (step S307). If the determination result in step S307 is negative, the HTML document analysis 1007 returns to step S304 and repeats the same processing as described above. If the determination is affirmative, the processing ends.

The above-described series of processing will be described more specifically in the case of analyzing the HTML document in FIG. In the above steps S301 and S302, the HTML document analysis 1007 divides the HTML document into line units, and considers that the information described in each line 1301-1307 is one element constituting the HTML document. ID = 0 to 6 are assigned. In step S304, the HTML document analysis 1007 performs processing for each element with ID = 0 to 6 (that is, the first to seventh lines 1301 to 1307 in FIG. 13).
(A) whether to include a character string,
(B) whether to include the storage position,
(C) Whether to include the link destination,
Respectively. Based on the determination results (a) to (c), it is specified which of the three element types “text”, “link”, and “image” the element belongs to. .

  That is, the HTML document analysis 1007 first determines that an element with ID = 0 (first row 1301) includes a character string but does not include a storage position and link information, and based on the determination result, the element type Is "text". Next, for the element with ID = 1 (second row 1302), it is determined that it includes the character string and link information but does not include the storage position. Based on the determination result, the element type is “link”. Identify. Next, for the element with ID = 2 (the third row 1303), it is determined that the storage position is included but the character string and link information are not included, and the element type is “image” based on the determination result. Identify. The same determination is performed for each element of ID = 3 to 6 (fourth to seventh rows 1304 to 1307), and the element type is specified based on the determination result.

The HTML element information storage unit 1008 receives the analysis result of the HTML document analysis 1007, and stores and stores it as HTML element information.
FIG. 15 is a diagram showing an example of HTML element information (obtained by analyzing the HTML document of FIG. 13) stored and stored in the HTML element information storage unit 1008 of FIG. In FIG. 15, the HTML element information includes, for each element (ID = 0 to 6) constituting the HTML document, the type of the element (here, “text”, “link”, or “image”). And information (in this case, a character string, a storage position, and a link destination) that the element has.

  The character string is information indicating the name of the element or the entire HTML document (such as “information about an celestial object”), and the storage position is information indicating the position where the entity of the element is stored (“moon.gif”). The link destination is information (such as “moon.html”) indicating the link destination of the element.

Returning to FIG. 12 again, next, the information extraction unit 1009 determines the type (here, the type stored in the extraction element type storage unit 1004 in step S204 from the HTML element information stored and stored in the HTML element information storage unit 1008 in step S209. Only information of elements belonging to “image”) is extracted (step S210).
Therefore, from the HTML element information shown in FIG. 15, information of elements belonging to “image” (three elements with ID = 2, 4, and 6), that is, storage positions of three images “moon. Only “gif”, “sun.gif” and “star.gif” are extracted.

  Next, the extraction information storage unit 1010 stores the information extracted by the information extraction unit 1009 in step S210 (step S211). Next, the information list box creation unit 1011 creates an information list box in which the information stored in the extracted information storage unit 1010 is stored in step S211 (step S212). This information list box includes the same number of boxes as the number of information extracted by the information extraction unit 1009 in step S210.

  Next, the information list box temporary storage unit 1012 temporarily stores the information list box created by the information list box creation unit 1011 in step S212 (step S213). Next, the display unit 1013 displays the information list box temporarily stored in the list temporary storage unit in step S213 (step S214).

  FIG. 16 is a diagram illustrating an example of an information list box displayed on the display unit 1013 in step S214. In FIG. 16, the information list box is composed of three boxes 1601 to 1603 arranged in a vertical line. When called from the top box 1601 in order, such as the 0th box, the 1st box,..., “Moon.gif” is in the 0th box 1601, and “sun.gif” is in the 1st box 1602. However, “star.gif” is described in the second box 1603, respectively.

  In the information list box of FIG. 16, the storage positions “moon.gif”, “sun.gif”, and “star.gif” of the entity of the image are described in the form of characters. The entity of the image may be acquired from the position, and the images of the moon, the sun, and the stars themselves may be described as shown in FIG.

Returning to FIG. 12 again, next, the input determination unit 1002 determines whether or not the instruction received by the input unit 1001 is an information selection instruction (step S215). If the determination result of step S215 is negative, the process returns to step S201, and the input unit 1001 accepts the next input instruction.
When the determination result of step S215 is positive, the information selection unit 1014 selects any one of the information stored in the extracted information storage unit 1010 in step S211 (step S216).

Here, details of the information selection processing in step S216 will be described.
FIG. 18 is a block diagram illustrating a configuration of the information selection unit 1014 of FIG. In FIG. 18, the information selection unit 1014 includes a focus unit 1801 and a determination unit 1802.
The focus unit 1801 focuses one of the boxes in the information list box displayed by the display unit 1013.

  The above-mentioned “focus on one box” means a process of changing the display mode of one box so that the one box is visually distinguished from other boxes, for example, the frame of the one box A process that emphasizes a line or changes brightness or color. In the following, a frame window 1901 applied to one box 1602 on the information list box as shown in FIG.

  In addition, when the up / down keys 1103 and 1104 of the input unit 1001 are pressed while the focus is on one box in the information list box displayed by the display unit 1013, the focus unit 1801 moves the focus up and down accordingly.

That is, in the information list box of FIG. 19, the focus 1901 applied to the box 1602 is moved to the box 1601 adjacent to the box 1602 when the up key 1103 is pressed, and the down key 1104 is pressed to press the down key 1104. It is moved to the adjacent box 1603.

  When the determination key 1107 is pressed in the information list box (see FIG. 19) displayed by the display unit 1013 while the focus unit 1801 focuses on any one box, the setting unit 1802 displays the information list box. The described information is determined as information to be selected by the information selection unit 1014.

  FIG. 20 is a flowchart showing details of the selection process in step S216 of FIG. “Max_num” described in FIG. 20 indicates the number of information extracted by the information extraction unit 1009 in step S210 of FIG. “Id” is determined by the focus unit 1801 among a plurality of boxes (here, a total of three boxes of the 0th to 2nd boxes 1601 to 1603) constituting the information list box displayed on the display unit 1013 in step S214. Indicates the box that currently has focus.

In FIG. 20, first, the focus unit 1801 performs an initialization process (step S401). In this initialization process, an initial value (here, 0) is set to “id”, and the number of extracted information (here, 3) is set to “max_num”.
Next, the focus unit 1801 focuses on the “id” -th box in the information list box (see FIG. 19) displayed by the display unit 1013 (step S402). That is, at the beginning of the selection process, the 0th (that is, the highest) box 1601 is focused.
Next, the input determination unit 1002 determines which of the up key 1103, the down key 1104, and the enter key 1107 is pressed, and notifies the focus unit 1801 and the setting unit 1802 of the determination result ( Step S403).

When the down key 1104 is pressed, the focus unit 1801 performs the following processing. First, “id” is incremented (step S404), and then it is determined whether “id” is larger than “max_num−1” (step S405). When the determination result in step S405 is negative, the focus unit 1801 returns to step S402 and focuses on the “id” -th box.
If the determination result in step S405 is affirmative, the focus unit 1801 returns “id” to the initial value (here, 0) (step S406), and returns to step S402.

  That is, when the down key 1104 is pressed, the focus applied to a certain box is moved to the lower adjacent box (for example, the focus applied to the first box 1602 is moved to the second box 1603). Moved). However, when the down key 1104 is pressed while the focus is on the lowest box (here, the second box 1603), the focus is on the highest box (here, the 0th box 1601). And jump moved.

When the up key 1103 is pressed, the focus unit 1801 performs the following processing. First, “id” is decremented (step S407), and then it is determined whether or not “id” is smaller than “0” (step S408) If the determination result in step S408 is negative, the focus unit 1801 Returning to S402, the “id” box is focused.
If the determination result of step S408 is affirmative, the focus unit 1801 sets “max_num−1” to “id” (step S409), and returns to step S402.

  That is, when the up key 1103 is pressed, the focus applied to a certain box is moved to the upper adjacent box (for example, the focus applied to the first box 1602 is changed to the 0th box 1601. Moved). However, when the up key 1103 is pressed in a state where the focus is on the top box (here, the 0th box 1601), the focus is on the bottom box (here, the second box 1603). And jump moved.
