Display device, image forming apparatus, and display control method
First Claim
1. A display device comprising:
- a display section configured to display an e-book containing a plurality of pages;
a detection section configured to detect first touch point and a second touch point different from the first touch point on a display surface of the display section; and
a display control section having a reading mode and a search mode, a page selected from among the plurality of pages contained in the e-book being displayed in the display section in parallel to the display surface of the display section in the reading mode, the plurality of pages being turned in response to movement of one of the first and second touch points in the search mode, whereinthe display control section changes mode from the reading mode to the search mode upon the detection section detecting the first and second touch points in the reading mode,the display section displays a fore edge of the e-book in a closed and upright state in response to mode change from the reading mode to the search mode,in the search mode, the display control section;
sets a speed of page turning of the plurality of pages to a first page turning speed in response to movement of the first touch point,performs page turning at the first page turning speed, andsuspends page turning in response to movement of the first touch point stopping, sets the speed of page turning to a second page tuning speed different from the first page turning speed before the first touch point stops in response to movement of the second touch point stopping,performs page turning at the second page turning speed, andsuspends page turning in response to the movement of the second touch point,the display control section selects a page opened at suspension of the page turning in response to movement of one of the first and second touch points stopping,the display control section changes the mode from the search mode to the reading mode in response to the detection section detecting disappearance of the first and second touch points, andthe page turning speed is the number of pages turned per unit time,in response to the movement of the second touch point different from the first touch point that stops, the display control section performs page turning in a direction different from a page turning direction in page turning before the first touch point stops,the page turning direction is a direction toward an end page or a front page of the plurality of pages, andthe control sectionperforms page turning of the plurality of pages in a direction toward an end page of the plurality of pages in response to movement of the first touch point, andperforms page turning of the plurality of pages in a direction toward a front page of the plurality of pages in response to movement of the second touch point.

Abstract
A display device (10) includes a display section (210), a detection section (220), and a display control section (100). The display section (210) displays a plurality of pages (P). The detection section (220) detects a plurality of touch points on a display surface of the display section (210). The display control section (100) performs page turning of the plurality of pages in response to movement of one of the touch points and suspends page turning in response to movement of the touch point stopping. In response to movement of a touch point different from the touch point that stops among the plurality of touch points, the display control section (100) performs page turning at a page turning speed different from that in page turning before the touch point stops. The turning speed is the number of pages (P) turned per unit time.
