Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information terminal device, and more particularly, to a small information terminal such as a portable telephone or a portable information terminal having a function of acquiring a document or an image from a server via the Internet.

[0002]

2. Description of the Related Art In recent years, as information has advanced, it has become possible for a user to immediately obtain various types of information via the Internet simply by inputting an access destination address to a personal computer. The information to be acquired is HTML (H
hypertext described in hyperTextMarkupLanguage) or MIME (Mult
ipuroseInternetMailExten
e.g., e.g. 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,
It can request the server to acquire information, or display the information acquired from the server on the screen. As such a browser, "Netscape (registered trademark) N"
aviator "or" InternetExplorer "
er "are widely used. In these browsers, image information (images) is acquired from the server via the Internet, and is obtained in the background (background screen).
And can be used as a screen saver.

[0003] Recently, with the miniaturization of devices, browsers and mailers have come to be mounted on small information terminal devices such as mobile phones and portable information terminals. Also in the case of small information terminal devices, similarly to the case of personal computers, there has been a demand for acquiring an image from a server and using it as a background screen or the like.

In the case of a personal computer, when an image is acquired from a server and used as a background screen, a plurality of images are accumulated and stored, and one of the plurality of images is selected and the background is selected. Can be used as a screen. Therefore, in the case of acquiring an image from a server and using it as a background screen in a small information terminal device,
As in the case of a personal computer, it is expected that a request to select an image will occur.

[0005]

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

It is possible to set the image obtained from the server on the background screen after the size of the image is once converted using an image processing tool or the like. However, this method cannot be performed unless the information terminal device has a relatively large storage capacity and can easily perform an input operation using a pointing device or the like. In particular, in the case of a mobile phone, the storage capacity is greatly restricted, and the input operation is extremely complicated because the ten keys and buttons are used. Therefore, a method using an image processing tool is not practical.

(Second Problem) In an information terminal device having no pointing device, particularly, in a mobile phone, a user desires one of a plurality of images obtained from a server.
It is not easy to select sheets.

In an information terminal device without a pointing device, the following method is conceivable for selecting one desired by a user from a plurality of images. That is, the names of a plurality of images are displayed on the screen, and when the user designates one name by key operation, the image corresponding to the name is selected. In this case, it is necessary to generate the name of each image, but it is not easy for an information terminal device because any image is merely a set of pixel data.

Therefore, a first object of the present invention is to provide an information terminal device which can acquire an image from a server, convert the size of the image, and use the image as a background screen.

[0010] A second object of the present invention is to obtain an image from a server, store the obtained image, and select and display an image desired by a user from a plurality of stored images. It is to provide a terminal device.

In FIG. 6, when the power of the mobile device is turned on, the input unit 401 starts an operation of receiving an instruction input from a user (step S101). next,
The input determination unit 402 determines whether the instruction received by the input unit 401 is an effective display area size setting instruction (Step S102). If the determination result in 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 the 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).

Next, the input judging section 402
It is determined whether or not the received instruction is an image size conversion form setting instruction (step S105). If the result of the determination in step S105 is negative, step S108 is subsequently executed. If the decision result in the step S105 is affirmative, the image size conversion form setting unit 4
In step 05, an image size conversion form is set (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).

Next, the input judging section 402
It is determined whether or not the received instruction is an image acquisition instruction (step S108). If the determination result in 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 via the Internet 17 (step S109). Next, the image storage unit 408 stores the image acquired by the image acquisition unit 407 in step S109 (step S110).

Next, the input judging section 402
It is determined whether or not the received instruction is an image selection instruction (step S111). If the result of the determination in 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 in the image storage unit 408 in step S110 (step S112).

Next, the protruding judging section 410 compares the size of the image selected by the image selecting section 409 in step S110 with the effective display area size stored in the effective display area size storage section 404 in step S104. It is determined whether the image protrudes from the effective display area 504 (step S113). If the determination result of step S113 is negative, subsequently, step S115
To S117 are executed.

If the decision result in the step S113 is affirmative, the image size converting section 411 proceeds to the step S107.
In step S104, the size of the image selected by the image selection unit 409 is stored in the effective display area size storage unit 40.
In step S107, the image size conversion form storage unit 4 is adapted to match the stored effective display area size.
Is converted using the form stored in step 06 (step S
114). Subsequently, steps S115 to S117
Is executed.

In step S115, display image temporary storage section 412 temporarily stores the display image. That is, the display image temporary storage unit 412 stores in the step S1
The image selected by the image selection unit 409 in 10 or the image obtained by size conversion by the image size conversion unit 411 in step S115 (that is, the image after the size conversion) is temporarily stored as a display image.

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

In the step S117, the input judgment section 402
Determines whether the instruction received by the input unit 401 is an image display stop instruction. When the determination result in step S117 is affirmative, the display unit 413 stops displaying the image, and when the determination result is negative, the above-described steps S101 to S1 are performed again.
17 is executed. 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 and storage processing in steps S103 and S104 is performed as follows. Several sizes that can be set as the effective display area size are prepared in advance in the effective display area size setting unit 403. When the user presses a specific button of the input unit 401, the effective display area size setting unit 403 , One of those sizes is selected and set 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. FIG.
In the example of, by the effective display area size setting unit 403,
Either (80 × 90) or (80 × 70) size is set, and the set size is stored by the effective display area size storage unit 404.

Alternatively, the user may operate the keyboard of the input unit 401 to specify an arbitrary size, 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 and storage processing 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 section, and when the user presses a specific button of the input section 401, the image conversion form setting section sets one of those forms. Select and set the form as the image size conversion form. Image size conversion form setting unit 40
5 is stored in the image size conversion form storage unit 406.

The image size conversion forms prepared in the image conversion form setting section are the first to third forms.
One image size conversion form. 7 to 9
FIG. 5 is a diagram visually illustrating first to third image size conversion forms. As shown in FIG. 7, the first image size conversion form is a form in which the image is reduced at the same vertical and horizontal ratio (that is, the resolution is reduced by thinning out the pixels at a fixed ratio). Using this first form, the converted image has a size that does not change its aspect ratio (that is, its shape is flattened) and that fits entirely within the effective display area.

As shown in FIG. 8, the second image size conversion form is a form for converting the size of an image to a smaller size by cutting out a part of the image. If this second form is used, the converted image will not lose its resolution, although the portion protruding from the effective display area will be deleted. The third image size conversion form is, as shown in FIG.
This is a conversion form that reduces the image at individual vertical and horizontal ratios. If this third form is used, the converted image has a flat shape, but has a size that fits entirely within the effective display area without excess or deficiency.
