[0070]
6 is a flowchart showing an operation in which the mobile device shown in FIG. 4 acquires an image from the WWW servers 18 and 19 and converts the size, and displays it as a background screen in the effective display area 504 shown in FIG. . Hereinafter, the operation of the mobile device according to the first embodiment of the present invention will be described with reference to FIGS.
[0071]
In FIG. 6, when the mobile device is turned on, the input unit 401 starts an operation of accepting an instruction input from the user (step S101). Next, the input determination unit 402 determines whether or not the instruction received by the input unit 401 is an effective display area size setting instruction (step S102). If the determination result of step S102 is negative, step S105 is subsequently executed.
If the determination result in step S102 is affirmative, the effective display area size setting unit 403 sets an effective display area size (step S103). Next, the effective display area size storage unit 404 stores the size set by the effective display area size setting unit 403 in step S103 (step S104).
[0072]
Next, the input determination unit 402 determines whether or not the instruction received by the input unit 401 is an image size conversion form setting instruction (step S105). If the determination result of step S105 is negative, step S108 is subsequently executed.
If the determination result of step S105 is affirmative, the image size conversion form setting unit 405 sets an image size conversion form (step S106). Next, the image size conversion form storage unit 406 stores the form set by the image size conversion form setting unit 405 in step S106 (step S107).
[0073]
Next, the input determination unit 402 determines whether the instruction received by the input unit 401 is an image acquisition instruction (step S108). If the determination result of step S108 is negative, step S111 is subsequently executed.
If the determination result in step S108 is affirmative, the image acquisition unit 407 acquires an image from the WWW servers 18 and 19 through the Internet 17 (step S109). Next, the image accumulation storage unit 408 accumulates and stores the image acquired by the image acquisition unit 407 in step S109 (step S110).
[0074]
Next, the input determination unit 402 determines whether or not the instruction received by the input unit 401 is an image selection instruction (step S111). If the determination result of step S111 is negative, step S117 is subsequently executed.
If the determination result in step S111 is affirmative, the image selection unit 409 selects one of the images stored and stored by the image storage storage unit 408 in step S110 (step S112).
[0075]
Next, the protrusion determination unit 410 compares the size of the image selected by the image selection unit 409 in step S110 with the effective display area size stored in the effective display area size storage unit 404 in step S104, and the image is valid. It is determined whether or not to protrude from the display area 504 (step S113). If the determination result of step S113 is negative, steps S115 to S117 are executed subsequently.
[0076]
If the determination result in step S113 is affirmative, the image size conversion unit 411 changes the size of the image selected by the image selection unit 409 in step S107 to the effective display region size stored in the effective display region size storage unit 404 in step S104. In order to be adapted, the image size conversion form storage unit 406 performs conversion using the form stored in step S107 (step S114). Subsequently, steps S115 to S117 are executed.
[0077]
In step S115, the display image temporary storage unit 412 temporarily stores a display image. That is, the display image temporary storage unit 412 stores the image selected by the image selection unit 409 in step S110 or the image obtained by the image size conversion unit 411 performing size conversion in step S115 (that is, the image after size conversion). Temporarily store as a display image.
[0078]
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.
[0079]
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.
[0080]
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
[0081]
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.
[0082]
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.
[0083]
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.
[0084]
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.
[0085]
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.
[0086]
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).
[0087]
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.
[0088]

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.
[0128]
Next, HTML document analysisPart1007 sets an initial value (0 in this case) to “k” indicating the identifier of the element to be analyzed (step S303). Next, HTML document analysisPart1007 determines whether the element “k” includes some information prepared in advance, and further, based on the determination result, the element “k” includes a plurality of element types prepared in advance. Which type belongs to which of them is specified (step S304).
[0129]
Next, HTML document analysisPart1007 notifies the HTML information storage unit of the analysis result of step S304, that is, what element type the element “k” belongs to and what information it has (step S305).
Next, HTML document analysisPart1007 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 analysisPartIn step 1007, the process returns to step S304, and the same process as described above is repeated. If the result is affirmative, the process ends.
[0130]
The above-described series of processing will be described more specifically in the case of analyzing the HTML document in FIG. HTML document analysis in steps S301 and S302 abovePart1007 divides the HTML document into units of lines, regards the information described in the lines 1301 to 1307 as one element constituting the HTML document, and assigns ID = 0 to 6 to each element. In step S304, HTML document analysis is performed.Part1007 is about each element of ID = 0-6 (namely, the 1st-7th lines 1301-1307 of 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. .
[0131]
That is, HTML document analysisPart1007 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. Based on the determination result, the element type is “text”. Identifies it. 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.
[0132]
HTML element information storage unit 1008 is an HTML document analyzerPartThe analysis result 1007 is received and stored as HTML element information.

[0146]
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.
[0147]
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.
[0148]
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.
[0149]
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.
[0150]
When the enter key 1107 is pressed,DecisionThe fixing unit 1802 determines the information described in the box focused by the focus unit 1801 as information to be selected by the information selection unit 1014 (step S410), and then the information selection process is ended. The
[0151]
Returning to FIG. 12 again, the element acquisition unit 1015 then has an element (here, an image) corresponding to the information (here, the storage position) selected by the information selection unit 1014 in step S216 in the HTML accumulation storage unit 1006. It is determined whether or not to perform (step S217). If the determination result in step S217 is affirmative, the element acquisition unit 1015 acquires the element from the HTML storage unit 1006 (step S218), and then step S221 is executed.
[0152]
If the determination result in step S217 is negative, the element acquisition unit 1015 acquires the element from the outside of the mobile device. Here, the element acquisition unit 1015 requests the HTML acquisition unit 1005 to transmit the element from the WWW servers 18 and 19 through the Internet 17. The element is acquired (step S219), and the HTML storage unit 1006 stores and stores the element (step S220). Thereafter, step S221 is executed.
In the following, in step S219, the element acquisition unit 1015 acquires the image (the element assigned ID = 2 in FIG. 15) stored in the position “moon.gif” from the WWW servers 18 and 19 through the Internet 17. Will be described.
[0153]
Next, the display image temporary storage unit 1016TheThe image acquired by the element acquisition unit 1015 in step S219 is temporarily stored as a display image (step S221). Subsequently, the display unit 1013 uses the image stored in the display image temporary storage unit 1016 as a background screen in the display area 1101. (Step S222).
[0154]
Next, the input determination unit 1002 determines whether or not the instruction received by the input unit 1001 is an image display stop instruction (step S223). If the determination result of step S223 is affirmative, the display unit 1013 stops the image display, and if negative, the above steps S201 to S223 are executed again.
