A user terminal has two screens. One screen displays content in a state intended by the creator of the content. The displayed content is composed of a plurality of bocks, and each block can be enlarged. Content corresponding to a block for which enlargement is directed is displayed on the other screen. The content displayed in the other screen has an enlarged form. Regarding the enlargement, rules are set. For example, an image or the like that is the subject of processing to be enlarged is processed without changing vertical and horizontal ratios.
