Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to an HTML (Hypertext Markup L) sent from a server via a network.
The present invention relates to an information processing apparatus that receives and displays data such as an anguage.

[0002]

2. Description of the Related Art In recent years, a form in which a device such as a printer connected to a network using a WWW (World Wide Web) technology is controlled from a terminal such as a personal computer or a workstation by a Web browser has been considered.

[0003] Further, it has been studied to mount a browser capable of displaying an HTML document on a liquid crystal panel of a device such as a copying machine and access the Internet from the device side.

A browser activated on a device such as a copying machine has the following limitations unlike a browser activated on a personal computer. (1) Incompatibility with browsers running on personal computers. Therefore, when the HTML is interpreted and displayed, it is displayed differently from the display on the personal computer. This is also due to the fact that HTML originally has different display characteristics depending on the browser. (2) The screen size is small. In general, a large screen is rarely provided on a device from the viewpoint of reducing costs and reducing the occupied area. In the case of a PDA (mobile terminal), there is the same limitation. For this reason, another URL (Uniform Resource Locator) may be prepared in a PDA or the like.

[0005] Usually, in order to eliminate a difference in display between browsers and a difference in screen size, an HTTP (Hypertext Transf.
er Protocol), the browser data (OS or browser type) sent to the server is referred to, and the HTML data returned by the server as a response is changed. For example, in the HTTP data shown in FIG. 10, the browser information is written in the underlined part in the figure, and the server refers to this and returns the HTML data suitable for the browser.

Further, as in the HTML data shown in FIG. 11, a code corresponding to the type and version of the browser is embedded in the HTML data sent from the server, and the data is displayed by the corresponding browser and version. I have.

[0007]

However, in such a conventional technique, although the difference in the display by the browser is eliminated to some extent, the processing for converting the HTML to the layout information is not strictly specified, and therefore the browser is not provided. There is a problem that the difference in display due to cannot be sufficiently eliminated.

[0008]

SUMMARY OF THE INVENTION The present invention is an information processing apparatus made to solve such a problem. That is, the present invention provides communication control means for inputting / outputting data to / from a server connected to a network, interpretation means for interpreting display information from data input by the communication control means, and display information interpreted by the interpretation means. Layout control means for controlling a display layout based on the layout information, and display means for displaying data based on the layout controlled by the layout control means.

In the present invention, the display information is interpreted by the interpreting means based on the data input by the communication control means, and the layout control means controls the layout for display based on the interpreted display information. . As a result, the display size of the display means and the layout suitable for the browser can be accurately set.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of an information processing apparatus according to the present invention. FIG. 1 is a block diagram illustrating an information processing apparatus according to the present embodiment, and shows an example in which the information processing apparatus is applied to a multifunction peripheral. Here, the MFP executes various functions such as copy / facsimile / printer, and is assumed to be connected to the Internet via a network N.

That is, the information processing apparatus 1 of the present embodiment
Is a communication control unit 2 for inputting and outputting data via the network N, an operation input / display unit 3 for performing an information processing operation, an image reading unit 4 including a scanner or the like, and an image reading unit 4. Image or network N
An image information storage unit 5 for storing an image transmitted from a host via a computer, and an image forming unit 6 for performing a predetermined process on the image
And an image output unit 7 composed of a printer engine, and a control unit 8 for controlling each unit.

FIG. 2 is a plan view for explaining an example of the operation input / display unit. The operation input / display unit 3 includes an input / output LCD 31 composed of a touch panel, “START”, and “ST”.
Various buttons B such as "OP" and a lamp L for notifying "communicating" and the like are provided. Various settings and operating conditions (number of copies, copy density, etc.) are displayed on the LCD 31, and a desired value can be input by the operator pressing the finger. In the present embodiment, HTML data can be displayed on the LCD 31 by a browser.

FIG. 3 is a configuration diagram of a browser that displays HTML data. HT that composes the browser
The ML parser 10 interprets the HTML data, and
The contents of the HTML are displayed on the LCD 31 (see FIG. 2) using the section 11 and the layout information control / drawing section 12.

FIG. 4 is a diagram for explaining the flow of processing when HTML is sent from the server. That is, the HTML data transmitted from the server is transmitted to the HTTP unit 11.
To the HTML parser 10 where the HTML
Is interpreted. The HTML parser 10 refers to the layout information included in the HTML, and sends the layout information to the layout information control / rendering unit 12. The layout information control / drawing unit 12 controls a layout suitable for the LCD 31 (see FIG. 2) based on the layout information.

In the present embodiment, such an HTML parser 10 interprets the layout information included in the HTML, and controls the layout information control / drawing unit 12 to control the layout suitable for the LCD as the display means. LCD
HTML data can be displayed with a layout that matches the display size of the HTML data.

Here, a specific example of the layout information will be described. The HTML parser 10 switches parser portions with reference to a description of a browser and a screen size suitable for display as layout information in the received HTML data.

FIG. 5 is a diagram showing an example of correspondence between a browser name and a parser path name. That is, the browser name and
Correspondence with a parser path name that stores a parser part for performing HTML interpretation corresponding to the browser is held by table data or the like. Then, the HTML parser refers to the browser name included in the received HTML, reads a parser path name corresponding to the browser name from the table data and the like, and reads a parser portion corresponding to the browser from the read parser path name. . By using this parser portion, it becomes possible to perform a display suitable for the transmitted HTML data.

For example, when HTML data as shown in FIG. 6 is transmitted, the HTML parser
After reading the part enclosed by the HEAD tags in L, the parser part is switched. As a result, the parser of the HAED part may be common. Also, the browser name is
The parser path name included in the comment line and corresponding to the browser name is read by referring to this. The output from any parser part is the layout information defined inside the browser, and the actual drawing is performed based on the layout information.

FIG. 7 is a diagram showing an example in which a parser and a screen size suitable for displaying this data are embedded in the HTML data. When such HTML data is received, the HTML parser 10 (see FIG. 3)
After reading the header part of this HTML data,
Load the parser into local memory from the path specified by the "PARSER" parameter. Thus, the display suitable for the HTML data can be performed by switching the parser portion.

FIG. 8 is a diagram showing an internal representation obtained after parsing the HTML tag information. That is, FIG.
(A) is an internal expression relating to the font size of characters and the like, interprets "5" specified by the parameter of the tag type "SIZE", and sets the font size of the characters and the like to 5 points.

FIG. 8B is an internal representation relating to the image. The image is referred to based on the path indicated by the tag type “SRC”, and the image is represented by the parameters specified by the tag types “WIDTH” and “HIGHHT”. Of the tag type "BORDE"
The thickness of the border of the image is set by the parameter designated by "R".

Here, the reduction / enlargement processing by the layout information control / rendering unit 12 (see FIG. 3) in the information processing apparatus of the present embodiment will be described. That is, the HTML parser 10
When the layout information control / drawing unit 12 interprets the tag as shown in FIG. 8 and sets the layout in the layout information control / drawing unit 12 (see FIG. 3), the layout information control / drawing unit 12 The layout is set by performing the scaling process.

The enlargement / reduction ratio is calculated by the following equation. Scale rate = number of screen width dots of device LCD / number of screen width dots suitable for display

That is, at the stage of receiving the HTML data, the parameter (number of dots) of the screen size suitable for display embedded in the header part of the HTML data (the number of dots) and the screen width of the LCD of the information processing apparatus (The number of dots), the enlargement / reduction ratio is obtained by the above formula.

When the tag information in the HTML data is parsed and the layout is set, the layout information control / rendering unit 12 (see FIG. 3) uses the scaling factor obtained in advance for the parameter relating to the font or image size. Multiply,
A scaling process suitable for the size of the LCD is performed.

For example, when the tag type shown in FIG. 9 is interpreted at a scaling ratio of 80%, the font size "SIZE"
Is 5 points × 80% = 4 points, the image size width “WIDTH” is 120 dots × 80% = 96 dots, the height “HIGHT” is 60 dots × 80% = 48 dots, and the border “BORDER” is 0 dots × 80% = 0
It becomes a dot.

[0027] Thus, the received HTML data can be subjected to scaling processing suitable for the size of the LCD, and can be displayed in the original layout of the HTML data.

[0028]

As described above, the information processing apparatus according to the present invention has the following effects. That is, since the display information is interpreted by the interpretation means based on the data input by the communication control means and the layout for the display is controlled by the layout control means, the display size of the display means and the layout suitable for the browser are set. This makes it possible to provide a screen display that is easy to see by sufficiently absorbing the difference in display by the browser.
