Abstract

Provided is a display apparatus that displays a first page and a second page. The display apparatus includes a determining unit configured to determine whether or not the layout of the first page is similar to the layout of the second page by comparing an object included in the first page with an object included in the second page which is different from the first page; and a display unit configured to display the first page on a screen based on a display area having been set by a user, wherein, if the determining unit determines that the layout of the first page is similar to the layout of the second page, the display unit displays the second page on the screen based on the set display area.

Claims

1. A display apparatus that displays a first page containing a plurality of objects and a second page containing a plurality of objects, the display apparatus comprising:

a memory; and

a processor configured to execute instructions stored in the memory, to act as units comprising;

(a) a setting unit configured to set one or more non-display objects among the objects contained in the first page;

(b) a first control display unit configured to carry out control to enlarge and display, on a screen, the objects contained in the first page, except the one or more non-display objects set by the setting unit;

(c) a receiving unit configured to receive an instruction to switch from display of the first page to display of the second page;

(d) a comparing unit configured to, in response to the received instruction, perform a comparison between the objects contained in the second page and the one or more non-display objects, wherein an object, of the objects contained in the second page, is determined to be equivalent to a non-display object, of the one or more non-display objects, if the object and the non-display object have in common at least one of;

a position and a size; and

(e) a second control display unit configured to, in response to the comparison, carry out control to enlarge and display, on the screen, the objects contained in the second page, except one or more objects determined from the comparison to be equivalent to any one of the one or more non-display objects set by the setting unit.

2. The display apparatus according to claim 1, wherein a display area of the screen is set based on a magnification at which a page is displayed on the screen.

3. The display apparatus according to claim 1, wherein a display area of the screen is set by scrolling and scaling of a page based on a user'"'"'s instruction.

4. The display apparatus according to claim 3, wherein the scrolling is performed by a swipe operation made by a user, and the scaling is performed by a pinch-out operation or a pinch-in operation made by the user.

5. The display apparatus according to claim 1, wherein an object of the one or more non-display objects is an image of a partial area in a page.

6. A system that processes a first page containing a plurality of objects and a second page containing a plurality of objects, the system comprising:

at least one memory; and

at least one processor configured to execute instructions stored in the at least one memory, to act as units comprising;

(a) a setting unit configured to set one or more non-display objects among the objects contained in the first page;

(b) a first control display unit configured to carry out control to enlarge and display, on a screen, the objects contained in the first page, except the one or more non-display objects set by the setting unit;

(c) a receiving unit configured to receive an instruction to switch from display of the first page to display of the second page;

(d) a comparing unit configured to, in response to the received instruction, perform a comparison between the objects contained in the second page and the one or more non-display objects, wherein an object, of the objects contained in the second page, is determined to be equivalent to a non-display object, of the one or more non-display objects, if the object and the non-display object have in common at least one of;

a position and a size; and

(e) a second control display unit configured to, in response to the comparison, carry out control to enlarge and display, on the screen, the objects contained in the second page, except one or more objects determined from the comparison to be equivalent to any one of the one or more non-display objects set by the setting unit.

7. The system according to claim 6, wherein a display area of the screen is displayed by scrolling and scaling of a page based on a user'"'"'s instruction, scrolling is performed by a swipe operation made by the user, and scaling is performed by a pinch-out operation or a pinch-in operation made by the user.

8. A display method for displaying a first page containing a plurality of objects and a second page containing a plurality of objects, the display method comprising:

setting one or more non-display objects among the objects contained in the first page;

carrying out control to enlarge and display, on a screen, the objects contained in the first page, except the one or more non-display objects;

receiving an instruction to switch from display of the first page to display of the second page;

comparing, in response to the received instruction, between the objects contained in the second page and the one or more non-display objects, wherein an object, of the objects contained in the second page, is determined to be equivalent to a non-display object, of the one or more non-display objects, if the object and the non-display object have in common at least one of;

a position and a size; and

carrying out, in response to the comparison, control to enlarge and display, on the screen, the objects contained in the second page, except one or more objects determined from the comparison to be equivalent to any one of the one or more non-display objects.

9. A non-transitory storage medium storing a program for causing a computer to execute a method for displaying a first page containing a plurality of objects and a second page containing a plurality of objects, the method comprising:

setting one or more non-display objects among the objects contained in the first page;

carrying out control to enlarge and display, on a screen, the objects contained in the first page, except the one or more non-display objects;

receiving an instruction to switch from display of the first page to display of a second page;

comparing, in response to the received instruction, between the objects contained in the second page and the one or more non-display objects, wherein an object, of the objects contained in the second page, is determined to be equivalent to a non-display object, of the one or more non-display objects, if the object and the non-display object have in common at least one of;

a position and a size; and

carrying out, in response to the comparison, control to enlarge and display, on the screen, the objects contained in the second page, except one or more objects determined from the comparison to be equivalent to any one of the one or more non-display objects.

10. A display apparatus that displays a first page containing a plurality of objects and a second page containing a plurality of objects, the display apparatus comprising:

a memory; and

a processor configured to execute instructions stored in the memory, to act as units comprising;

(a) a setting unit configured to set one or more non-display objects among the objects contained in the first page;

(b) a first control display unit configured to carry out control to enlarge and display, on a screen, the objects contained in the first page, except the one or more non-display objects;

(c) a receiving unit configured to receive an instruction to switch from display of the first page to display of the second page;

(d) a comparing unit configured to, in response to the received instruction, perform a comparison between the objects contained in the second page and the one or more non-display objects, wherein an object, of the objects contained in the second page, is determined to be equivalent to a non-display object, of the one or more non-display objects, if the object and the non-display object have in common at least one of;

an object position, an object size, and an object type, wherein the object type is one of the group consisting of photograph, line, table, graphic, decorative object, and page number; and

(e) a second control display unit configured to, in response to the comparison, enlarge and display, on the screen, the objects contained in the second page, except one or more objects determined, by the comparing unit, to be equivalent to any one of the one or more non-display objects.
