Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic book device,
In particular, the present invention relates to an electronic book device provided with a mechanism for changing the cycle of automatic page turning according to the content of the displayed page.

[0002]

2. Description of the Related Art Conventionally, this kind of electronic book device with an automatic page turning function has been used to adjust the page turning speed, that is, the display time for each page so as to correspond to the reading speed peculiar to an individual. ing.

For example, as disclosed in Japanese Unexamined Patent Publication No. 4-47458, an automatic page turning variable cycle clock generator capable of specifying a cycle from the outside is provided, and an individual page can be selected from a predetermined cycle list by an operation from the outside. The page turning speed is adjusted by selecting the cycle suitable for the reading speed.

[0004]

However, it is desirable that the pages of a book are originally turned over when the reader (user) finishes viewing the contents of the page. Here, the time required for the reader to finish reading the page depends on the content of each page, and the display time should be longer for the page with more displayed content. Therefore, if pages are turned at a constant cycle that has been set regardless of page contents as in the prior art, there is a problem that the time required for the reader to read and the page display time become excessive or insufficient.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention.

The book data storage device 101 stores book data which is the content of coded books.
As shown in FIG. 2, the content of the book includes header data 201 that holds information unique to the book and page data 202 that holds information about each page in the book. The header data 201 includes initial setting data 203 and a page address 204 indicating a storage address and a data amount of each page data 202. The initial setting data 203 includes at least a display start page, and a character display reference time TC, a figure display reference time TF, and an image display reference time TI, which are display times per unit amount of characters, figures, and images. The page data 202 includes an in-page data address 205 indicating a relative storage address and data type of each character / graphic / image data in the page, and each character / graphic / image. Of character data 206, graphic data 207, and image data 208.

The book data input device 102 first reads the header data 201 from the book data storage device 101, and sets the page initial value in the initial setting data 203 in the page counter 111. Next, the book data input device 1
02 reads the page data 202 corresponding to the value of the page counter 111 with reference to the in-page address data 204, and transfers it to the display screen generation device 103.

The display screen generating apparatus 103 has an in-page data address 2 in which the location of each data of characters, figures and images is recorded from the input page data 202.
05, the coded data of characters, figures, and images are sequentially converted into page image data. At this time, the book data input device 102 counts the numbers NC, NF, and NI of characters, figures, and images, and the display time setting device 104.
Output to. Next, the display screen generation device 103 outputs the generated page image data to the display device 105, and outputs the display image generation end signal 121 to the input / output control device 106 as soon as the output is completed.

The display time setting device 104 formulas the page display time TS of the page based on the input character quantity NC, figure quantity NF, and image quantity NI (1.01).
And output to the input / output control device 106.

TS = TC.NC + TF.NF + TI.NT (1.01) For example, TC = 0.1 sec, TF = 1 sec, TI =
If set to 1 sec, NC = 100 characters, N
When F = 1 and NI = 1, TS = 12 sec.

Upon receipt of the display image generation end signal 121, the input / output control device 106 receives the internal image state flag 112.
To ON state. When the input / output control device 106 receives the page display time TS from the display time setting device 104, the input / output control device 106 receives the image status flag 112 and the timer status flag 11.
When both 3 are in the ON state (how this state will be described later), the image state flag 112 and the timer state flag 113 are set to OFF, the timer control signal 124 is output to the timer 107, and page display is performed. The time TS is set in the page display time register 114, and the timer 107
When the timer starts counting, the input / output control device 106 outputs the display control signal 122 to the display device 105 to display the page image data of the page. Further, the input / output control device 1
06 is an input control signal 12 to the book data input device 102.
3 is output and input of page data for the next page is started. The timer 107 sends a time-up signal 125 to the input / output control unit 106 when the display time set in the page display register 114 elapses after the start of clocking.
Set to.

If either the image state flag 112 or the timer state flag 113 is OFF at the time of inputting the page display time TS, the state is maintained until both flags are turned ON. In addition, at startup,
Image state flag 112 is OFF, timer state flag 1
13 is initialized to ON.

When the book data input device 102 receives the input control signal 123 from the input / output control device 106, after incrementing the page counter 111, the page data 202 corresponding to the page indicated by the page counter 111.
Enter.

By repeating the above process,
An automatic page turning operation is realized.

[0017]

As described above, the electronic book device with the automatic page turning function according to the present invention sets the display time based on the contents of the display page and stores it according to the contents of the page being displayed by the display time setting device. Since the display time is automatically adjusted by the display, it is possible to provide an automatic page turning function according to the reading speed of the reader.
