  However, the page switching of the conventional electronic display device as described above merely presents the device of the expression for switching the page, the feeling when turning the book with one hand, the page switching according to it, It does not provide a sense of page turning. Therefore, it gives the user the impression of mechanical page switching and cannot provide a sense of turning pages during reading. As a result, such an operational sensation detracts from the attractiveness of the electronic display device.

  The present invention has been made in view of these problems, and an object of the present invention is to provide an electronic display device capable of switching pages (turning pages) as if turning.

  An electronic display device according to the present invention includes a display unit that displays content, an operation unit that performs a page switching operation of the content displayed on the display unit, and the content displayed on the display unit based on the operation of the operation unit. A control unit that controls page switching from the first page to the second page, and the control unit gradually changes the display position of the first page in order to update the display of the display unit in the page switching. The display unit is moved out of the display area of the display unit, the display position of the second page is gradually moved into the display area of the display unit, and the moving speed of the first page and the second page is set to In the latter half of the switching, it is set to change with at least two stages of deceleration.

  The control of this control unit facilitates the transition to the next page when switching pages, and it is possible to imagine the operation of a page when the actual book is turned over. Hold it and get the feeling of turning a book with one hand.

  Further, the control unit of the electronic display device according to the present invention is configured such that the display area of the next page in the composite image is decelerated in multiple stages in the second half of the page turning, and the first display is changed according to the operation of the operation unit. The change of the moving speed of the page and the second page and the process time from the start of page switching to the end of page switching are controlled.

  With such a configuration, the user can switch pages in various modes.

  In addition, the operation unit includes a touch sensor, and the control unit changes the moving speed of the first page and the second page and starts page switching according to the movement of the finger tracing the touch sensor. The process time from the end of page switching to the end of page switching may be controlled.

  With such a configuration, the user can change the moving speed with a simple operation.

  Further, the acceleration of the two-stage deceleration may be set in the final phase of the page switching, and the deceleration near the final phase may be set smaller than the deceleration far from the final phase.

  By this control of the control unit, the transition to the next page becomes even smoother.

  In addition, the control unit of the electronic display device of the present invention sets the moving speeds of the first page and the second page so as to decelerate after acceleration in the first half of page switching.

  By doing this, the acceleration feeling when turning pages is emphasized.

  In addition, the control unit of the electronic display device according to the present invention is configured so that the moving speed of the first page and the second page is constant until the speed of deceleration in the first half of page switching reaches the speed of deceleration in the second half of page switching. Set to maintain.

  In this way, a smooth feeling can be obtained by increasing the display area of the next page at a constant speed during page turning.

Further, the present invention is a page switching control method for controlling page switching from the first page to the second page of the content displayed on the display unit in the electronic display device, which method includes the first page. Is gradually moved out of the display area of the display unit, the display position of the second page is gradually moved into the display area of the display unit, and the first page and the second page are moved. The moving speed is set so as to change with at least two stages of deceleration in the second half of the page switching.
A program for causing a computer to execute such a method is also included in the present invention.

  The electronic display device of the present invention can display page switching and page turning that feel as if hand turning is being performed, not mechanical page switching.

  FIG. 1 is a perspective view showing an external appearance of an electronic display device 10 according to an embodiment of the present invention. The casing of the electronic display device 10 includes a thin box-shaped rectangular portion 11 and a substantially cylindrical gripping portion 13 connected to one side of the rectangular shape, and the display portion 12 is disposed in the rectangular portion 11. The part 13 is provided with a substantially E-shaped operation part 14. In addition, a battery serving as a power source for the apparatus is accommodated in the grip portion 13.

  As shown in FIG. 2, the user grasps the grip portion 13 of the electronic display device 10 with the right hand 41 or the left hand 42, traces the E-shape of the operation portion 14 with the thumb of the gripped hand, and displays it on the display portion 12. Yes Select a content such as a book and switch the page.

  As shown in FIG. 3, the E-shaped operation unit 14 includes a plurality of touch sensors 15 a to 15 h arranged along the E-shape, and is determined in advance based on the order of touch sensors touched by the finger and the time interval thereof. The displayed operation is performed.

  For example, when the electronic display device 10 is held with the right hand, when the content selection menu is displayed on the display unit 12, as shown in FIG. 4A, the touch sensor is changed from 15b → 15c → 15e. If the user sequentially traces with the finger, the selection position of the content moves downward on a menu including a large number of content titles. Conversely, if the user traces in the order of 15e → 15c → 15b, the selection position moves upward.

  Further, as shown in FIG. 4B, when the touch sensor is traced with a finger in the order of 15e → 15d, the first page of the content selected on the menu is displayed on the display unit 12.

  Further, as shown in FIG. 4C, when the touch sensor is traced with a finger in the order of 15a → 15b, the page of the displayed content is switched in the forward direction, and when traced in the order of 15b → 15a, the reverse direction Page switching to is performed. At this time, if the tracing speed is larger than a predetermined value s2, the page is turned at a high speed. If the tracing speed is between s1 and s2, the page is turned at a medium speed. If the tracing speed is less than s1, the page is turned. Pages are turned at a low speed (the state in which pages are turned one page at a time in response to an operation of tracing with a finger in this way is referred to as “normal mode”). Also, after touching the touch sensor with your finger, if you keep touching without removing your finger from the touch sensor, you will enter the “medium speed mode” where you can switch pages continuously, and if you keep touching for a predetermined time or longer Then, a transition is made to the “high speed mode” in which a predetermined number of pages (for example, every 10 pages) are skipped and switched. As described above, in accordance with the operation on the operation unit 14, the control unit 16 controls the change in the moving speed of the page and the process time from the start of page switching to the end of page switching.

  Further, as shown in FIG. 4D, when the touch sensor is traced with a finger in the order of 15h → 15g, the operation unit 14 of the electronic display device 10 is switched to an operation corresponding to left-hand holding.

  FIG. 5 shows an operation when the electronic display device 10 is held with the left hand. This is the case with right hand holding, and content selection is performed by tracing the touch sensor in the order of 15h → 15f → 15e or vice versa (FIG. 5A), and display of the selected content The start is performed by tracing the touch sensor in the order of 15e → 15d (FIG. 5B), and the page switching is performed by tracing the touch sensor in the order of 15h → 15g or vice versa (FIG. 5 ( c)) Further, switching to right hand holding is performed by tracing the touch sensor in the order of 15b → 15a. A configuration in which a gravity sensor and an acceleration sensor are separately provided and the display of the display unit 12 is automatically reversed when the electronic display device 10 is flipped up and down without touching the touch sensor may be employed.

  FIG. 6 is a block diagram showing a configuration of the electronic display device 10. The device 10 includes a display unit 12, a touch sensor 15 that functions as an operation unit, a storage unit 17 that stores content, a temporary storage unit 18 that temporarily stores display images, and a control unit 16 that controls display. have.

  The storage unit 17 is a storage medium such as a memory card attached to the apparatus, and stores a large number of browsing contents together with menu information thereof. The storage medium is generally removable and is provided with a copyright protection function, and the content cannot be copied to another recording medium, but the type is not particularly limited.

  The temporary storage unit 18 includes a volatile memory, and the page displayed on the display unit 12 of the content to be browsed and the pages before and after the page are read from the storage unit 17 and temporarily stored.

  The control unit 16 holds a program in which the control operation is defined in association with input information of the touch sensor 15. When information is input from the touch sensor 15, the control unit 16 identifies the validity of the information and is effective. In this case, the display of the display unit 12 is controlled according to the program.

  Next, a page switching display operation in the electronic display device 10 will be described.

  When the power of the apparatus 10 is turned on, the control unit 16 reads the menu information from the storage unit 17 and displays it on the display unit 12, and highlights the first title among the many titles included in this menu screen. Then, the right-handed display control that is initialized is started. In addition, as shown in FIG.4 (d), when there exists input from 15g following 15h of the touch sensor 15, the time in the meantime is measured with a clock (not shown), and measurement time was preset. When it is shorter than the threshold value, this input information is identified as valid, and the display control is switched to left-handed display control.

  As shown in FIG. 4A, when there is an input in this order from 15b, 15c, 15e of the touch sensor 15, the control unit 16 measures the time between them, and the measurement time is preset. If the input information is shorter than the threshold, the input information is identified as valid, and the title position to be highlighted on the menu screen is moved downward. Similarly, when there is an input in the order of 15e, 15c, and 15b, when the information is identified as valid, the position of the title to be highlighted on the menu screen is moved upward.

  Further, as shown in FIG. 4B, when there is an input from 15d following 15e of the touch sensor 15, the control unit 16 displays this input information when the measurement time is shorter than a preset threshold value. The first and second pages of the title content that is identified as valid and highlighted on the menu screen are read from the storage unit 17, stored in the temporary storage unit 18, and the first page is displayed. Displayed on the unit 12.

  Further, as shown in FIG. 4C, when there is an input from 15b following 15a of the touch sensor 15, the control unit 16 sets the measurement time between them to preset times h0, h1, h2 (h0>). Compare with h1> h2). When the measurement time is longer than h0, the input information is invalidated. When h0 ≧ measurement time> h1, page switching is performed in the low-speed normal mode. When h1 ≧ measurement time> h2, medium speed is obtained. In the normal mode, page switching is executed. When h2 ≧ measurement time, page switching is executed in the high-speed normal mode.

  The page switching in the normal mode is performed by using the image data of the first page and the second page stored in the temporary storage unit 18 to display an image in which the display position of the second page gradually changes as shown in FIG. The display unit 12 sequentially updates the display using the combined image. At this time, in the low-speed normal mode, the temporal increase in the display area of the second page occupied in the composite image is set as shown in FIG. In the present invention, the increase in the display area of the second page means that the first page (current page, first page) moves outside the display area of the display unit 12 while the second page (next page, second page). Page) moves into the display area of the display unit 12.

  FIG. 7 shows a state in which the display area of the second page occupying the composite image increases with time similarly to FIG. 13, and tn on the horizontal axis indicates the update time of the composite image at the start of page switching ( 0) and the vertical axis represents the ratio (%) of the display area of the second page in the composite image at time tn and the display area of the second page in the composite image at time t (n-1). Represents the difference from the percentage (%).

  By following the setting shown in FIG. 7, the display area of the second page accelerates and increases rapidly until time t2 (t1: 8.3%, t2: 22.1%), and 2 occupies the composite image at time t2. The display area of the page reaches 30.4%. The display area of the second page is decelerated after this rapid acceleration. From t3 to t7, the display area increases by 12.4% for each update of the composite image, and the second page occupies the composite image at time t7. The display area reaches 92.4% cumulatively. After that, the display area of the second page decreases, but the deceleration acceleration is not constant, the increase at time t8 is 5.5%, 1.4% at time t9, and 0.2% at time t10. 6%, the acceleration of deceleration decreases as the time approaches t11, and the display area of the second page reaches 100% cumulatively at time t11. t11 is the time when the elapsed time from the page switching start time (0) is 1100 ms. Further, “acceleration of deceleration” is the same as “deceleration”, and “deceleration” corresponds to the inclination of the graph of FIG. Therefore, in the case of “two-stage deceleration”, the speed decreases with at least a two-stage graph inclination.

  In this way, when increasing the display area of the second page to a predetermined level, rather than realizing it by equal acceleration, it is higher than the predetermined level as in the period from 0 to t3 in FIG. After accelerating, decelerating to a predetermined level emphasizes the acceleration and gives a feeling of turning.

  Further, when the method of increasing the display area of the second page is decelerated in the second half of the page switching, the page switching is not performed at a constant acceleration, but during the period from t7 to t11 in FIG. As the final phase is approached, the acceleration of deceleration is reduced, so that a reverberation can be given to the switching to the second page, and the impression of mechanical page switching can be eliminated.

  Further, in the medium speed normal mode, the temporal increase in the display area of the second page in the composite image is set as shown in a graph b in FIG. 8 (the graph a in FIG. 8 is the same as FIG. 7). Shows slow normal mode).

  By following this medium-speed normal mode, the display area of the second page is accelerated and increased to the time t2 (t1: 8.3%, t2: 28.2%), and the composite image at the time t2 is displayed. The display area occupied by the second page reaches 36.5%. The display area of the second page is decelerated after this rapid acceleration. From t3 to t5, it increases by 19.3% for each update of the composite image, and the second page occupies the composite image at time t5. The display area reaches 94.4% cumulatively. In the deceleration process in the latter half of the page switching, the increase is 4.1% at time t6 and 1.4% at time t7, and the display area of the second page reaches 100% cumulatively at time t8. t8 is the time when the elapsed time from the page switching start time (0) is 800 ms.

  Also in the normal mode of medium speed, in the first half of page switching, after accelerating to a predetermined level or higher, the speed is decelerated to a predetermined level to emphasize the feeling of acceleration. Therefore, you can feel the hand turning.

  Further, in the second half of page switching, the acceleration of deceleration decreases as the final phase of page switching is approached, and therefore, switching to the second page can have a reverberation.

  Further, in the high-speed normal mode, the temporal increase in the display area of the second page in the composite image is set as shown by a graph c in FIG.

  By following this high-speed normal mode, the display area of the second page in the composite image at time t1 reaches 55.2%. Thereafter, the increase in the display area of the second page slows down, increasing by 37.3% at time t2, 5.5% at time t3, and 1.9% at time t4. The display area reaches 100% cumulatively. t5 is the time when the elapsed time from the page switching start time (0) is 500 ms.

  Also in this high-speed normal mode, after accelerating greatly at time t1 in the first half of page switching, it is decelerated at time t2 to emphasize the feeling of acceleration. Further, during the period from t2 to t5, the closer to the final phase of page switching, the slower the acceleration of deceleration, so that the switching to the second page has a reverberation.

  When the second page is displayed on the display unit 12, the control unit 16 reads the next page from the storage unit 17, and stores the currently displayed page and the previous and subsequent pages in the temporary storage unit 18.

  Then, as shown in FIG. 4C again, when there is an input from 15b following 15a of the touch sensor 15, the control unit 16 performs page switching to the next page in the normal mode in the above-described procedure. To do. When there is an input from 15a following 15b of touch sensor 15, control unit 16 performs page switching to the previous page in the normal mode in the same procedure.

  In addition, when there is an input from 15b following 15a of the touch sensor 15 and the input from 15b continues thereafter, the control unit 16 measures the duration with a clock (not shown). Then, when the measurement time exceeds a preset time m1, a “medium speed mode” in which page switching is continuously performed is executed. In this medium speed mode, the temporal increase in the display area of the second page in the composite image is set as shown in FIG.

  In FIG. 9, the first page switching is performed from 0 to t3, the next page switching is performed from t3 to t6, the next page switching is performed from t6 to t9, and from t9 to t12. The next page is switched. In each page switching, the pattern in which the display area of the next page in the composite image increases in time is the same. In the case of the first page switching, the increase is 89% at time t1 and 11% at time t2. At time t3, the display area of the next page reaches 100% cumulatively. t3 is the time when the elapsed time from the page switching start time (0) is 300 ms.

  Also in the medium speed mode, after accelerating greatly at the beginning (t1) of page switching, the vehicle decelerates at time t2 to emphasize the acceleration feeling. Also, in the deceleration process, the acceleration of deceleration is reduced as the final phase of page switching is approached, so that the transition to the next page has a reverberation.

  In addition, the control unit 16 sequentially reads out the next page from the storage unit 17 and stores it in the temporary storage unit 18 in time for switching to the next page displayed on the display unit 12.

  Further, the control unit 16 measures the time from the start of the medium speed mode with a clock (not shown), and the input from the touch sensor 15b is stopped before the measurement time reaches the time m2 (m2> m1). In this case, the page switching to the subsequent page is stopped when the page switching during the implementation is completed. Further, when the measurement time reaches the time m2 without stopping the input from the touch sensor 15b, the “high speed mode” for switching the page to the page after k pages is executed.

  In this high-speed mode, page switching is performed as follows: (n + k) page, (n + 2k) page, (n + 3k) page, (n + 4k) page after page n. To express the difference from medium-speed mode, A distance (margin) is provided between pages to be switched.

  In this case, the temporal increase in the display area of the next page in the composite image is set as shown in FIG. Here, page switching from (n + k) to page (n + k) is performed from 0 to t3, page switching from (n + 2k) is performed from t3 to t6, and page (n + 3k) is performed from t6 to t9. Page switching is performed, and page switching from (n + 4k) to (n + 4k) is performed from t9 to t12. However, in this page switching, switching between pages including a margin is performed, but since the vertical axis in FIG. 10 indicates a value of% focusing on only the page, the accumulation exceeds 100%.

  Also in this high-speed mode, after accelerating greatly at the beginning of page switching (t1), it decelerates at time t2 to emphasize the acceleration feeling. Also, in the deceleration process, the acceleration of deceleration is reduced as the final phase of page switching is approached, so that the transition to the next page has a reverberation.

  Further, the control unit 16 sequentially reads out the corresponding pages from the storage unit 17 and stores them in the temporary storage unit 18 in time for the next page switching to be displayed on the display unit 12.

  In addition, when the input from the touch sensor 15b is stopped, the control unit 16 stops the subsequent page switching to the page when the page switching during the implementation is completed.

  Here, the processing in the forward medium speed mode and the high speed mode has been described, but the same applies to the reverse direction.

  The above operation control will be described generally with reference to FIG. FIG. 11 illustrates changes in the image at each stage in the normal mode shown in FIG.

  (A) has shown the change of the image in the time t1-t3. At this stage, the acceleration is further emphasized by decelerating after the movement is accelerated once. (B) after (A) shows changes in the image at times t3 to t7. At this stage, the image moves at a constant speed, so that a smooth feeling can be given to the movement.

  Next, (C) shows a change in the image from time t7 to t9. At this stage, the movement is gradually decelerated and the page movement speed is reduced. (D) after (C) shows a change in the image at time t9 to t11. At this stage, the reverberation when the page movement stops can be produced by reducing the acceleration of deceleration from the previous (D).

  In this example, the display position of the current page 1 is gradually moved out of the display area of the display portion surrounded by the frame, and the display position of the next page 2 is gradually moved into the display area of the display portion within the frame, Composite images are generated sequentially. Further, as shown in (C) and (D), the moving speeds of the current page 1 and the next page 2 are set to change at least in two stages of deceleration acceleration in the second half of page switching. This control is common not only in the other normal modes shown by b and c in FIG. 8, but also in the medium speed mode in FIG. 9 and the high speed mode in FIG.

  Further, it is desirable that the acceleration of the two-stage deceleration is set in the final phase of page switching as shown in (C) and (D). Further, as shown in (D), the acceleration of deceleration near the final phase is set to be smaller than the acceleration of (C) deceleration farther from the final phase than (D). Is emphasized. This control is common not only in the other normal modes shown in FIGS. 8B and 8C but also in the medium speed mode in FIG. 9 and the high speed mode in FIG.

  Further, as in the step (A), it is desirable to set the moving speeds of the current page 1 and the next page 2 to decelerate after acceleration in the first half of page switching. Further, as in step (B), the moving speed of the current page 1 and the next page 1 is maintained at a constant speed until it reaches the deceleration of (C) in the second half of the page switching after the deceleration in the first half of the page switching. It is desirable to set so as to. These controls are the same in the other normal modes shown in FIG.

  In this way, in this electronic display device, the appearance of the next page in page switching is sharpened, so that the impression of mechanical page switching can be diminished and the feeling of turning can be produced. Especially, in the latter half of page switching, when decelerating the increase in the display area of the next page, the acceleration of the deceleration is lowered as it approaches the final phase of page switching, so without sudden feeling, Soft landing can be performed to the next page, and a reverberation can be given to switching to the next page.

  In this deceleration process, at least the acceleration of the deceleration is set to two stages, a1 and a2 (<a1), the acceleration closer to the final phase of page switching is set to a2, and the far side from the final phase of page switching The effect is obtained by setting the acceleration to a1.

  Note that the configuration and operation procedure of the operation unit described here, mode setting such as normal mode, medium speed mode, and high speed mode, and setting of the increase characteristic of the next page image in each mode are all examples. However, the present invention is not limited to them. It is also possible to configure the operation unit with a cross key or a plurality of keys divided vertically and horizontally.

  Although various embodiments of the present invention have been described above, the present invention is not limited to the matters shown in the above-described embodiments, and those skilled in the art can make modifications and applications based on the description and well-known techniques. This is also the scope of the present invention, and is included in the scope for which protection is sought.

  The electronic display device of the present invention can make the user feel “page switching (page turning)” as if turning a book, and can read electronic books such as novels, art books, and photo books. The present invention can be widely applied to various electronic display devices such as terminals and image viewers that sequentially display taken pictures.
