Abstract

The purpose of the invention is to make page transitions in display control for sequentially displaying partial images of a page image not feel unnatural to a user regardless of whether the page progression direction is right to left or left to right. The invention is provided with a control unit (41) which, upon receiving a scroll instruction from an operation unit (42) while the last partial image of the current page is being displayed on a display unit (43), causes a display unit (43) to display the first partial image of the next page after having the display unit (43) display a page-crossing image which straddles the boundary between the page image of the current page and the page image of the next page. The control unit (41) sequentially moves the display region of the page-crossing image from the bottom left of the page image of the current page to the top right of the page image of the next page when the page progression direction is right to left, and sequentially moves the display region of the page-crossing image from the bottom right of the page image of the current page to the top left of the page image of the next page when the page progression direction is left to right.

Description

ビューワ装置、表示制御方法及びプログラムViewer device, display control method, and program
　本発明は、電子書籍を構成する複数ページのページ画像を表示する際に表示画面のサイズに対応した部分画像を順次表示するビューワ装置、表示制御方法及びプログラムに関する。 The present invention relates to a viewer device, a display control method, and a program for sequentially displaying partial images corresponding to the size of a display screen when displaying a plurality of page images constituting an electronic book.
　近年の情報技術の革新に伴い、紙媒体にプリントされる書籍をデジタル化し、携帯端末などのビューワ装置で閲覧するという情報配信形態が確立されてきた。 With recent innovations in information technology, an information distribution form has been established in which books printed on paper media are digitized and viewed on a viewer device such as a portable terminal.
　特許文献１～３には、電子コミックの１ページ分の画像（ページ画像）を１画面では表示不可能である場合に、ページ画像から１画面で表示可能な部分画像を観察順序の情報に基づいて順次に表示するビューワ装置が開示されている。例えば、ユーザによる画面送り操作があるたびに、観察順序を示す情報に基づいて順次に表示領域を移動させ、その表示領域内に含まれる部分画像ごとに表示を行う。 In Patent Documents 1 to 3, based on the information of the observation order, partial images that can be displayed on one screen from page images when an image (page image) of one page of an electronic comic cannot be displayed on one screen. A viewer device that sequentially displays images is disclosed. For example, each time the user performs a screen feed operation, the display area is sequentially moved based on information indicating the observation order, and display is performed for each partial image included in the display area.

　しかしながら、現在ページの最後の部分画像が表示された状態で、次ページの部分画像を表示させるために、画面送り指示を入力すると、現在ページの最後の部分画像から次ページの先頭の部分画像に表示がいきなり切り換わるため、閲覧者に違和感を与えるという問題がある。 However, when the screen advance instruction is input to display the next partial image in the state where the last partial image of the current page is displayed, the last partial image of the current page is changed to the first partial image of the next page. Since the display is suddenly switched, there is a problem that the viewer feels uncomfortable.
　具体的には、紙媒体に印刷された日本語のコミック（漫画書籍）であれば、見開きの右ページの左下部分から左ページの右上部分に、閲覧者の視線がゆっくり移動するのに対して、日本語の電子コミックでは、画面送り指示を入力すると、現在ページである右ページの最後の部分画像から次ページである左ページの先頭の部分画像に、表示がいきなり切り換わってしまう。つまり、電子コミックの閲覧者に対し、紙媒体に印刷されたコミックを閲覧する場合とは異なる表示となり、閲覧者に違和感を与えてしまうことになる。 Specifically, in the case of Japanese comics (manga books) printed on paper media, the viewer's line of sight slowly moves from the lower left part of the right page to the upper right part of the left page. In Japanese electronic comics, when a screen advance instruction is input, the display is suddenly switched from the last partial image on the right page, which is the current page, to the first partial image on the left page, which is the next page. That is, the display is different from the case of browsing a comic printed on a paper medium for a viewer of an electronic comic, which gives the viewer a sense of incongruity.
　また、紙媒体に印刷された日本語のコミック（漫画書籍）であれば、見開きの右ページの左下部分から左ページの右上部分に、閲覧者の視線がゆっくり移動するのに対して、紙媒体に印刷された英語のコミック（漫画書籍）であれば、見開きの左ページの右下部分から右ページの左上部分に、閲覧者の視線がゆっくり移動する。つまり、日本語のような右から左のページ進行方向属性の電子コミックと、英語のような左から右のページ進行方向属性の電子コミックとでは、ページ進行方向が異なるため、ページ切り換わり時に閲覧者に違和感を与えない表示制御を行うためには、ページ進行方向属性に基づいて表示制御を行う必要があるが、ページ進行方向属性に基づいてページ切り換わり時の表示制御を切り替える技術が存在しなかった。 In addition, in the case of a Japanese comic (manga book) printed on a paper medium, the viewer's line of sight slowly moves from the lower left part of the right page to the upper right part of the left page, whereas the paper medium In the case of an English comic (comic book) printed on, the viewer's line of sight slowly moves from the lower right part of the left page of the spread to the upper left part of the right page. In other words, because the page progression direction is different between an electronic comic with a right-to-left page progression direction attribute such as Japanese and an electronic comic with a left-to-right page progression direction attribute such as English, it is viewed when the page changes. In order to perform display control that does not give the user a sense of incongruity, it is necessary to perform display control based on the page progress direction attribute, but there is a technology for switching display control at the time of page switching based on the page progress direction attribute. There wasn't.
　本発明の目的は、ページ進行方向が右から左または左から右のいずれであっても、ページ画像の部分画像を順次表示する表示制御においてページが切り換わるときに、紙媒体の電子書籍を閲覧するときと同様な見え方となるように表示制御を行うことができ、閲覧者に違和感を与えないようにすることが可能なビューワ装置、表示制御方法及びプログラムを提供することにある。 An object of the present invention is to view a paper medium electronic book when a page is switched in display control for sequentially displaying partial images of a page image, regardless of whether the page traveling direction is right to left or left to right.

In this example, the page image 80L of the next page has six frames (seventh frame F7, eighth frame F8, ninth frame F9, tenth frame F10, eleventh frame F11, and twelfth frame). Among these, the seventh frame F7, the eighth frame F8, and a part (upper left portion) of the tenth frame F10 are included in the first display area of the page image 80R of the next page. It is.
　以上のように、制御部４１は、複数ページのページ画像のうちの現在ページのページ画像における表示部４３の画面サイズに対応した表示領域の部分画像を表示部４３に表示させる第１の表示制御手段であって、現在ページの最初の表示領域から最後の表示領域まで操作部４２によって画面送り指示の入力を受け付けるごとに表示領域を順次進めて、その表示領域の部分画像を表示部４３に表示させる第１の表示制御手段として機能する。また、制御部４１は、現在ページのページ画像における最後の表示領域の部分画像を表示部４３に表示させた状態で、操作部４２によって画面送り指示の入力を受け付けた場合、現在ページのページ画像と次ページのページ画像との境界を跨いだページ跨ぎ画像を表示部４３に表示させた後、次ページのページ画像における最初の表示領域の部分画像を表示部４３に表示させる第２の表示制御手段として機能する。また、制御部４１は、第２の表示制御手段として、現在ページのページ画像と次ページのページ画像とを互いに隣接させて構成した合成ページ画像を記憶部４５に一時的に記憶させ、その合成ページ画像からページ跨ぎ画像を抽出する。また、制御部４１は、第２の表示制御手段として、ページ進行方向属性が右から左のページ進行方向を示す場合には、現在ページのページ画像の左下の表示領域から次ページのページ画像の右上の表示領域に向かってページ跨ぎ画像の表示領域を順次移動させ、ページ進行方向属性が左から右のページ進行方向を示す場合には、現在ページのページ画像の右下の表示領域から次ページのページ画像の左上の表示領域に向かってページ跨ぎ画像の表示領域を順次移動させる。 As described above, the control unit 41 causes the display unit 43 to display the partial image of the display area corresponding to the screen size of the display unit 43 in the page image of the current page among the page images of a plurality of pages. Each time a screen feed instruction is input by the operation unit 42 from the first display region to the last display region of the current page, the display region is sequentially advanced, and a partial image of the display region is displayed on the display unit 43. It functions as the first display control means. When the control unit 41 receives an input of a screen feed instruction by the operation unit 42 in a state where the partial image of the last display area in the page image of the current page is displayed on the display unit 43, the page image of the current page Second display control for causing the display unit 43 to display a partial image of the first display area in the page image of the next page after the page straddling image straddling the boundary between the page image of the next page and the page image of the next page is displayed. Functions as a means. Further, the control unit 41 temporarily stores, in the storage unit 45, a combined page image configured by adjoining the page image of the current page and the page image of the next page as the second display control unit, and combines the combined page image. A page-stretching image is extracted from the page image. Further, as the second display control means, the control unit 41, when the page progress direction attribute indicates the page progress direction from right to left, the page image of the next page from the display area at the lower left of the page image of the current page. If the page straddling image display area is moved sequentially toward the upper right display area and the page progress direction attribute indicates the page progress direction from left to right, the next page starts from the lower right display area of the page image of the current page. The display area of the page straddling image is sequentially moved toward the upper left display area of the page image.

However, the present invention includes a case where an electronic book is acquired from a recording medium such as a memory card.
　また、制御部４１は、複数ページのページ進行方向を示すページ進行方向属性を取得するページ進行方向属性取得手段として機能する。 Further, the control unit 41 functions as a page progress direction attribute acquisition unit that acquires a page progress direction attribute indicating the page progress direction of a plurality of pages.
　また、操作部４２は、表示部４３に表示させた部分画像を次に進める画面送り指示（単に「送り指示」ということもある）の入力を受け付ける指示入力手段として機能する。 Also, the operation unit 42 functions as an instruction input unit that receives an input of a screen advance instruction (sometimes simply referred to as “forward instruction”) for proceeding with a partial image displayed on the display unit 43.
　＜画面戻り指示とページ跨ぎエフェクト＞
　以上では、画面送り指示により現在ページのページ画像の最後の表示領域から次ページのページ画像の最初の表示領域に向かってページ跨ぎを行う表示制御を例に説明したが、更に、画面戻り指示（単に「戻り指示」ということもある）により現在ページのページ画像の最初の表示領域から前ページのページ画像の最後の表示領域に向かってページ跨ぎするようにしてもよい。 <Screen return instructions and page-to-page effects>
In the above, the display control in which the page straddling from the last display area of the page image of the current page to the first display area of the page image of the next page is described as an example by the screen advance instruction. The page may be straddled from the first display area of the page image of the current page toward the last display area of the page image of the previous page.
　例えば、操作部４２によって、部分画像の表示領域を戻す画面戻り指示の入力を受けつける。制御部４１は、現在ページのページ画像のうち最初の表示領域の部分画像を表示部４３に表示させた状態で、操作部４２が画面戻り指示の入力を受け付けた場合、現在ページのページ画像と前ページのページ画像との境界を跨いだページ跨ぎ画像を表示部４３に表示させる。 For example, the input of the screen return instruction for returning the display area of the partial image is received by the operation unit 42. When the operation unit 42 receives an input of a screen return instruction with the display unit 43 displaying a partial image of the first display area of the page image of the current page, the control unit 41 The page straddling image straddling the boundary with the page image of the previous page is displayed on the display unit 43.
　この場合、制御部４１は、ページ進行方向属性が右から左のページ進行方向を示す場合には、現在ページのページ画像の右上の表示領域から前ページのページ画像の左下の表示領域に向かってページ跨ぎ画像の表示領域を順次移動させ、ページ進行方向属性が左から右のページ進行方向を示す場合には、現在ページのページ画像の左上の表示領域から前ページのページ画像の右下の表示領域に向かってページ跨ぎ画像の表示領域を順次移動させる。 In this case, when the page progress direction attribute indicates the page progress direction from right to left, the control unit 41 moves from the upper right display area of the page image of the current page toward the lower left display area of the page image of the previous page. When the page spanning image display area is moved sequentially and the page progress direction attribute indicates the page progress direction from left to right, the display from the upper left display area of the page image of the current page to the lower right display of the page image of the previous page The display area of the page-spanning image is sequentially moved toward the area.
　＜画面送りのバリエーション＞
　図７及び図８には、表示部４３の表示画面のサイズに応じて表示領域を移動させる場合を示したが、このような場合に本発明は限定されない。つまり、図７及び図８に示した例では、表示部４３の表示画面に対応するサイズの表示領域に複数のコマ（例えば２つのコマ）が入っている場合には、画面送り指示が入力されると、表示領域を２コマ分進めているが、必ず１コマごとに表示領域を進めるようにしてもよい。また、画面送り指示が入力されると、吹出し１つごとに表示領域を進めるようにしてもよい。 <Screen feed variations>
