As shown in the figure, the 'main page 3 (203)' displayed on the screen may be additionally converted to the 'main page 4 (204)', which is the main page having the next main page number '4'.

As a result, when a main page change command is applied from the user in a situation where a specific sub page is being displayed on the screen, the main page change unit 116 does not change the next page in units of sub pages, but moves to the next main page. You can switch pages. That is, the main page change unit 116 may convert a page to a subsequent main page in units of a main page according to a main page change command applied by the user.

According to an embodiment of the present invention, the electronic device 110 may further include a region dividing unit 117 , a ratio calculating unit 118 , a region selecting unit 119 , and a main page display unit 120 .

The region divider 117 is configured to display the first subpage, which is any one of at least one subpage subordinate to the first main page, after a slide show execution command for the presentation document is applied by the user. When a simultaneous display command of the main page is applied from the user in a situation being displayed on the screen, the first sub-page is divided into rectangular regions of a preset size, and n (n is a natural number greater than or equal to 2) divided regions create them

The ratio calculator 118 checks whether an object inserted into the first sub-page exists, and when it is confirmed that at least one first object is inserted into the first sub-page, for each of the n divided areas , calculates a ratio occupied by an area of a portion overlapping with the at least one first object on the first subpage.

The region selector 119 selects the divided region calculated with the smallest ratio among the n divided regions as the simultaneous display region for displaying the main page.

When the simultaneous display area is selected, the main page display unit 120 additionally displays the first main page in the simultaneous display area on the first sub-page being displayed on the screen.
