First Claim
1. A computer-implemented file conversion method for extracting, from an HTML file acquired through the internet and composed of a plurality of pieces of data displayable on a display unit and with a start and an end of each piece of data indicated by respective identifiers in the form of tags, data displayable on a limited-capability device, in accordance with the identifiers, and for outputting the extracted data to the limited-capability device, the file conversion method comprising:
- a step of determining what characteristic of the HTML file is to be converted;
a step of detecting the tags by reading the file;
a step of determining whether the data indicated by the detected tags is displayable on the limited-capability device;
a step of extracting the data, the start and the end of which are indicated by the detected tags and which is determined to be displayable on the limited-capability device;
a step of displaying on the display unit the extracted data to be shaped for display on the limited-capability device;
a step of reading out a stored conversion rule that is specific to each set of tags and that has having shaping conditions including character count per line and image size limitations;
a step of converting, based on the read-out conversion rule, the extracted data to meet the limitations for display on the limited-capability device; and
a step of outputting an output file that is newly created from the extracted data that has been shaped in the step of shaping, as a different file from the HTML file, to the limited-capability device for display,wherein the step of extracting the data is performed by referencing a processing condition data area of a memory file that defines the tags of the HTML data that is displayable on the limited-capability device, andwherein the processing condition data area has a data structure containing a plurality of categories, and wherein the file conversion method further comprises selecting the processing condition data to be used, based on the category selected from among the plurality of categories.

Abstract
A file conversion method, a data converter, and a file display system for extracting data handled by a limited capability display device from a plurality of pieces of data displayable on a standard display unit with a start and an end of each piece of data indicated by respective identifiers and for outputting the extracted data to the device in which the identifier is detected by reading the file and it is then determined whether identified data can be displayed on the limited capability display device. The data identified by the identifier is extracted and an output file, different than the file that was read, is created from the extracted data.

8. A converter for extracting, from an HTML file acquired through the internet and composed of a plurality of pieces of data displayable on a display unit and with a start and an end of each piece of data indicated by respective identifiers in the form of tags, data displayable on a connected limited-capability device, and for outputting the extracted data to the limited-capability device, the file converter comprising:
-
means for selecting a characteristic of the HTML file that is to be converted; file storage means for storing the HTML file; detector means for detecting the tags corresponding to the selected characteristic that indicates an area of the data to be displayed on the limited-capability device from the HTML file stored in said HTML file storage means; extractor means for extracting, from said HTML file, the data with the start and the end thereof indicated in accordance with the identifier detected by the detector means, wherein the extracted data is one of a map, a coupon, and address information, wherein the data is extracted by referencing a processing condition data area of a memory file that defines the tags of the HTML data that is displayable on the limited-capability device, and wherein the processing condition data area has a data structure containing a plurality of categories, and the processing condition data to be used is selected based on the category selected from among the plurality of categories; convertor means for converting date of the HTML file that is between the tags according to a stored predetermined conversion rule for the tags; output means for outputting the extracted data to the limited-capability device, whereby the limited-capability device displays on a screen thereof one of the map, the coupon, and the address information; and control means for controlling the detector means to detect the tags indicating the start and the end of the displayable data for the purpose of converting the data displayable on the limited-capability device from said HTML file stored in said file storage means based on the stored predetermined conversion rule having shaping conditions, for controlling said extractor means to extract, as a new output file with the selected characteristic having been converted, data including the start and the end indicated by the tags from said HTML file, and for controlling said output means to output the new output file to the limited-capability device for display. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 22)
