Abstract

A display control method for displaying thumbnail images of respective pages of one document having a plurality of pages on a display unit includes: generating an image in which respective thumbnail images of the plurality of pages are arranged in a predetermined direction based on the sequence of pages so as to partially overlap with adjacent thumbnail images, at least a thumbnail image of a first selected page selected from the plurality of pages is disposed on the frontmost surface, and the gap between a thumbnail image of a second selected page other than the first selected page and a thumbnail image of a page which is before or after the second selected page is larger than before the second selected page is selected; and displaying the generated image in the generating on the display unit.

Claims

1. A display control method for displaying thumbnail images of respective pages of one document having a plurality of pages on a display unit, comprising:

generating an image in which respective thumbnail images of the plurality of pages are arranged in a predetermined direction based on the sequence of pages so as to partially overlap with adjacent thumbnail images, at least a thumbnail image of a first selected page selected from the plurality of pages is disposed on the frontmost surface, and the gap between a thumbnail image of a second selected page other than the first selected page and a thumbnail image of a page which is before or after the second selected page is larger than before the second selected page is selected; and

displaying the image generated in the generating on the display unit.

2. The display control method according to claim 1,

wherein the respective thumbnail images of the plurality of pages are images in which the corresponding page is erected on a horizontal plane provided within an imaginary space and rotated from a predetermined reference position within the imaginary space about an imaginary rotation axis crossing the horizontal sides of the page, and the page is viewed overhead within the imaginary space.

3. The display control method according to claim 1,

wherein a rotation angle of the thumbnail image of the second selected page is smaller than the rotation angle of each of the thumbnail images of pages which are before and after the second selected page.

4. The display control method according to claim 1,

wherein a plan-view image of the first selected page having a larger size than the thumbnail image is displayed together with the respective thumbnail images of the plurality of pages.

5. The display control method according to claim 1,

wherein the display unit includes a plurality of scanning lines, a plurality of data lines, and a plurality of pixels formed corresponding to the intersections between the plurality of scanning lines and the plurality of data lines and changes the gradation of the pixels by a writing operation of applying a voltage to the pixels several times, and

wherein the method further includes

determining pixels of which the gradation is to be changed among the plurality of pixels by comparing image data representing an image to be newly displayed on the display unit and scheduled image data representing an image scheduled to be displayed on the display unit by the writing operation in progress, and

starting the writing operation with respect to pixels which are determined to be the pixels of which the gradation is to be changed and in which the writing operation is not being performed so that the pixels have a gradation set by the image data, and starting the writing operation with respect to pixels which are determined to be the pixels of which the gradation is to be changed and in which the writing operation is being performed so that the pixels have a gradation set by the image data after the writing operation being performed is finished.

6. A display apparatus comprising:

a display unit that displays thumbnail images of respective pages of one document having a plurality of pages;

a display image generation unit that generates an image in which respective thumbnail images of the plurality of pages are arranged in a predetermined direction based on the sequence of pages so as to partially overlap with adjacent thumbnail images, at least a thumbnail image of a first selected page selected from the plurality of pages is disposed on the frontmost surface, and the gap between a thumbnail image of a second selected page other than the first selected page and a thumbnail image of a page which is before or after the second selected page is larger than before the second selected page is selected; and

a controller that causes the image generated by the display image generation unit to be displayed on the display unit.

7. An electronic apparatus comprising the display apparatus according to claim 6.
