FIG. 4 is a diagram showing an example of the software configuration of the user terminal 1. The user terminal 1 includes a data reception section 111, a text data acquisition section 112, and a screen data creation section 113. Note that each functional unit included in the user terminal 1 may be realized, for example, by executing a program such as JavaScript received from the management server 2.

The data receiving unit 111 receives image data and lightweight document data from the management server 2 .

The text data acquisition unit 112 acquires text data from lightweight document data. The text data acquisition unit 112 can also acquire text data as well as the position and style of the text data from the lightweight document data. The location can be a location on a page. The style may include at least the size of characters (font size). Note that the text data acquisition unit 112 can also extract links set in the text data based on the lightweight document data.

The screen data creation unit 113 creates screen data for displaying image data so that text data can be selected. The screen data can be written in HTML, for example. For example, the screen data creation unit 113 can display text data by superimposing image data on an element with a background. At this time, the screen data creation unit 113 may display the text data transparently. The screen data creation unit 113 can display a page of document data superimposed on image data according to the position and style acquired by the text data acquisition unit 112. This allows the user to select transparent text on the image data at the position and size displayed on the image. The screen data creation unit 113 can set the link in the text if the link is extracted. For example, a link can be set in the HREF attribute of the A element, and text can be set as the content of the A element.

FIG. 5 is a diagram showing a display example of screen data created by the screen data creation unit 113. A page image 411 representing each page of document data is displayed on the web page 40 displayed based on the screen data, and text 412 displayed on the page is arranged to be superimposed on the page image 411. Since the text 412 is text data, it can be selected by dragging the pointer 413 on the web page 40 and the text can be copied to the clipboard.

<Operation>
