Embodiments of the present invention will be described below in detail with reference to the drawings.

(1) First Embodiment (1-1) Configuration of First Embodiment FIG. 2 is a block diagram showing a display device according to a first embodiment of the present invention. That is, the display device 1 detects an operation of the touch panel 3 arranged on the liquid crystal display panel 2 by the touch panel controller 4, and accesses an electronic book (not shown) under the control of the central processing unit (CPU) 5 based on the detection result. . Here, the e-book is
It is a recording medium such as a magnetic disk, an optical disk, and a memory card on which a novel or the like is recorded. The magnetic disk is a floppy disk, a click (registered trademark of IO Mega Corporation), the optical disk is a mini disk (registered trademark of Sony Corporation), a DVD-RAM, etc., and the memory card is a memory stick (Sony Corporation). And the like).

Further, the display device 1 displays a video random access (VRAM) based on the access result.
LCD (Liquid) with a work area secured in Memory 6
The contents recorded in the electronic book are displayed on the liquid crystal display panel 2 by driving the controller 7.
Thus, the display device 1 displays the contents of the electronic book on the liquid crystal display panel 2.

In these controls, the central processing unit 5 secures a work area in a random access memory (RAM) 8 and executes a predetermined processing procedure recorded in a read-only memory (ROM) 9 to execute a user operation. The contents of the display are switched in response to the operation of.

FIG. 1 is a front view showing the entire configuration of the display device 1. As shown in FIG. Here, in the display device 1, the above-described circuit block is housed in a thin plate-shaped housing, and the liquid crystal display panel 2 and the touch panel 3 are stacked and arranged on the upper surface of the housing. Thus, the display device 1 can switch the display screen variously by operating the display screen.

In this display, the central processing unit 5
Displays a frame W such that the pages overlap each other on the right and left pages, as in the case where the book is viewed stereoscopically from the near side, and displays the contents of the electronic book inside the frame W. . Further, in the display of the frame W, the central processing unit 5 detects the number of pages before and after the currently displayed page, and the pages appearing to be overlapped on the right and left pages, respectively, so as to correspond to the number of pages before and after. The frame W is displayed by the thicknesses DR and DL of the frame. In this embodiment, for the right page, the overlap of this page is formed on the right side and below the right page, and for the left page, the overlap of this page is formed on the left side and below the left page. . Thus, in this embodiment,
In the display corresponding to the fore-edge and the ground on both the left and right pages, the frame W is formed by the corresponding linear display in the top in the width corresponding to the number of pages.

Thus, the central processing unit 5 displays the actual book in such a manner that the thickness of the portion corresponding to the fore-edge and ground (Noshita) portions can be recognized.

As a result, the central processing unit 5 can visually grasp the position of the currently displayed page as if the book was actually opened, thereby improving the usability. . By the way, in the state shown in FIG. 1, when the right page side is the unread page side and the left page side is the finished page side, the portion corresponding to the foreground and ground of the right page is displayed thickly. This means that many unread pages are left on the right side of the page.

FIG. 3 and FIG. 4 are flowcharts showing the processing procedure of the central processing unit 5. By executing this processing procedure with the electronic book displayed as described with reference to FIG. The display screen is switched in response to.

That is, the central processing unit 5 proceeds from step SP1 to step SP2, and determines whether or not the user operates the touch panel 3 to input data based on the data input from the touch panel controller 4. Here, if a negative result is obtained, the central processing unit 5 repeats step SP2, and waits for a user operation.

When the user operates the touch panel 3 to input data, the central processing unit 5
Moves from step SP2 to step SP3, where it is determined whether or not this user operation is an operation related to page turning. Here, when the user drags a predetermined position on the touch panel with a finger or the like, the central processing unit 5 determines that the operation is related to page turning, and proceeds to step SP4.

The central processing unit 5 executes this step SP
At 4, it is determined whether or not this page feed operation is a page feed to the previous page. Here, if a positive result is obtained, the central processing unit 5 proceeds to step SP5, decrements the page number and returns the page number to the number corresponding to the previous page, whereas if a negative result is obtained, the central processing unit 5 proceeds to step SP6. The page number is incremented and the page number is advanced to the number corresponding to the next page.

In this series of determinations, the central processing unit 5, as shown by arrows in FIGS. 5 and 6, respectively, indicates a portion corresponding to the ground formed below the frame W or the inside of the frame W. In, when the touch on the touch panel 3 is detected and then dragged across the page display from the pressed position, it is determined that the operation is a page feed operation.

At this time, if the setting of the electronic book is such that the right page side is the unread page side and the left page side is the finished page side, the drag from the left page side to the right page side is performed as shown in FIG. It is determined that the drag from the right page side to the left page side is a page feed to the next page as shown in FIG. On the other hand, for example, in the case of an electronic book of Japanese literature, when the setting of the electronic book is the page side on which the right page has been read and the page on the left is an unread page, as shown in FIG. The drag on the right page side is determined to be a page feed to the next page, and conversely, the drag from the right page side to the left page side is determined as a page feed to the previous page as shown in FIG.

The central processing unit 5 switches the display in the frame W to the previous page side and the next page side in step SP5 and step SP6, respectively, based on the result of this determination,
It returns to step SP2.

On the other hand, in the case of such an operation other than the drawing across the pages, the central processing unit 5 determines that the operation is other than the page feed, and determines from step SP3 to step S3.
Move to P7.

Here, the central processing unit 5 determines whether or not the operation is related to a jump. Here, as shown in FIG.
When a pressing operation of the touch panel 3 is detected at a portion corresponding to a fore edge which is a display portion where the pages of the frame W on the right page side or the left page side overlap, the central processing unit 5 determines that the operation is related to jumping. . When the pressing operation of the fore-edge portion is detected in this way, the central processing unit 5 switches the display color to the fore-edge portion in a diagonal band shape, and forms a drawing guide using the band-shaped display B.

When the central processing unit 5 determines that the operation is related to jumping in this way, it proceeds from step SP7 to step SP8 (FIG. 4), and sets a page number according to the drawing by the user. Here, the page number is set by assigning the widths DR and DL of the fore-edge to the corresponding number of unread pages and the number of pages that have been read, respectively, and set according to the position of the pressing operation by the user. That is, for example, when the 100th page is currently displayed on the right page side and 100 unread pages remain on the right page side, the central processing unit 5 sets the right side of the band-shaped display B from the inside. When the 1/4 portion is pressed, the page number is set to 125 pages, which is the currently displayed 100 page plus 1/4 of the remaining 100 pages.

After setting the page number in this manner, the central processing unit 5 proceeds to step SP9, and determines whether or not the pressing operation of the touch panel 3 has been completed. Here, if a negative result is obtained, the central processing unit 5 proceeds to step S
The process proceeds to P10, and the page number detected in this way is displayed near the area pressed by the balloon F.
Return to 8.

On the other hand, when the pressing operation of the touch panel 3 is completed, the central processing unit 5 proceeds from step SP9 to step SP11, switches the display in the frame W to the display corresponding to the page number, and then proceeds to step SP2. Return.

On the other hand, if it is determined in step SP7 (FIG. 3) that the operation is not a jump-related operation,
That is, when the background portion other than the display of the book is pressed, the central processing unit 5 proceeds from step SP7 to step SP12. Here, the central processing unit 5 displays a predetermined menu, sets a bookmark on, for example, the currently displayed page in response to a user operation in this menu, and then returns to step SP2.

When the bookmark is set in this manner, the central processing unit 5 uses the color specified by the user in the fore-edge portion as if the bookmark were sandwiched between the corresponding pages as shown in FIG. A display screen is formed by arranging the bookmark display BM.

When the bookmark portion displayed in this way is pressed by the user, the central processing unit 5 switches the display in the frame to the display of the corresponding page, and thereby the bookmark of the bookmark selected by the user is displayed. Display the page.
