Technical Field

[0001] The present invention relates to the technical field of information processing, and particularly to a comparison reading method, an electronic device, and a computing storage medium. Background Art

[0002] At present, e-books have become a common reading mode, and major manufacturers have successively launched e-book readers, e-book reading applications, and so on. When reading a book, users often need to compare the context and read the content of several pages before or after the current page. In the related art, first, bookmarks need to be added to the pages to be compared, then turn to other pages for reading. After that, when the user wants to return to the compared page, the bookmark list needs to be called up first, and then the bookmark corresponding to the compared page is clicked. It can be seen that the related art requires users to perform cumbersome operations, and also cannot display two pages simultaneously for users to perform comparison reading, and cannot simulate the comparison reading effect when reading a paper book. Summary of the Invention

[0021] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present invention can be more thoroughly understood and the scope of the present invention can be fully conveyed to those skilled in the art.

[0022] Figure 1 Shows a flowchart of the comparison reading method provided by an embodiment of the present invention, as Figure 1 shown, the method includes the following steps:

[0023] Step S110, receive the comparison reading trigger operation performed by the user on the book, and obtain the comparison book content corresponding to the book.

[0024] The comparison reading trigger operation is used to switch to the comparison reading mode. The user can perform the comparison reading trigger operation within the book display area during the reading process. The comparison reading trigger operation can be a long - press operation, a double - click operation, a specific gesture operation, a touch operation on a specific button, a stylus trigger operation, etc. The present invention does not limit the specific form of the comparison reading trigger operation.

[0025] The comparison book content corresponding to the book is the book content that needs to be compared and is fixedly displayed. For example, it can be the book content pre - marked by the user, or the book content displayed in the book display area when the user performs the comparison reading trigger operation.

[0026] Step S120, fixedly display the comparison book content in the first - screen area of the screen.

[0027] In the comparison reading mode, the screen includes a first screen area and a second screen area. Among them, the first screen area is used to fixedly display the content of the comparison book, and the second screen area is used to display other book content except the content of the comparison book. The first screen area and the second screen area can be split-screen areas on the left and right, or split-screen areas on the top and bottom. The present invention does not limit this.

[0028] In an optional manner, comparison identification information is also displayed within the first screen area to inform the user that the book content presented within the first screen area is the fixed comparison book content.

[0029] Step S130: Receive a touch operation of the user within the second screen area of the screen, and display the target book content corresponding to the touch operation within the second screen area.

[0030] Among them, the second screen area is used to display other book content except the content of the comparison book, and the target book content corresponding to the touch operation belongs to this other book content. The user can perform a touch operation within the second screen area to switch the book content displayed in the second screen area, so that the user can freely view other book content except the content of the comparison book within the second screen area.

[0031] Among them, the touch operation can be a page-turning operation, a sliding operation, or a page-switching operation. For example, if the first screen area fixedly displays the first page of the book, then all other reading pages of the book except the first page are displayed through the second screen area. When the user performs a downward page-turning operation within the second screen area, the next page of the reading page currently displayed in the second screen area is switched for display; when the user performs an upward swipe operation within the second screen area, the subsequent book content of the currently displayed book content is revealed following the upward swipe operation; when the user performs a page-switching operation within the second screen area, for example, the user selects to switch to the last page of the first chapter through a table of contents list or a progress bar, then the last page of the first chapter is switched for display within the second screen area. It can be seen that the first screen area fixedly displays the book content that needs to be compared, and at the same time, the user can switch the book content displayed in the second screen area by performing an operation within the second screen area, restoring the comparison reading effect and experience when reading a paper book.

[0032] According to the comparison reading method provided by this embodiment, in response to the user performing a comparison reading trigger operation to switch to the comparison reading mode, the comparison book content is fixedly displayed within the first screen area, other book content except the comparison book content is displayed within the second screen area, and the user can switch the book content displayed in the second screen area by performing an operation within the second screen area, so that the user can freely view other book content of the book within the second screen area, realizing comparison reading without the user performing complex operations, and restoring the comparison reading effect where the comparison page is fixed and other pages can be freely viewed when reading a paper book.

[0033] Figure 2 The flowchart of the comparison reading method provided by another embodiment of the present invention is shown. This method is used to switch to the comparison reading mode in the split-screen reading mode. As Figure 2 shown, the method includes the following steps:

[0034] Step S210, according to the resource file of the book, split-screen display the book content of the book through the first screen area and the second screen area of the screen.

[0035] In some large-screen devices (such as tablet computers, e-ink readers, foldable screen devices, etc.), a split-screen reading mode is usually provided. In the split-screen reading mode, the screen contains two book display areas, namely the first screen area and the second screen area. The first screen area and the second screen area display two consecutive book reading pages of the book at the same time.

[0036] The resource file of the book is an EPUB file. The EPUB file is typeset and rendered, and the book content of the book is split-screen displayed through the first screen area and the second screen area of the screen.

[0037] Step S220, receive the comparison reading trigger operation performed by the user in the first screen area, obtain the book content currently presented in the first screen area, and obtain the comparison book content.

[0038] Among them, a switching entry for the comparison reading mode is set in both the first screen area and the second screen area. The user can perform an operation in the first screen area or the second screen area to switch to the comparison reading mode.

[0039] When receiving the comparison reading trigger operation performed by the user in the first screen area, obtain the book content currently presented in the first screen area as the comparison book content. In the method of this embodiment, the resource file of the book is an EPUB file. The EPUB file has the advantages of high flexibility and easy calculation. Through the EPUB file, the book content presented in the first screen area can be quickly determined.

[0040] If the e-book application does not support dual-document opening, then execute step S230-step S240; if the e-book application supports dual-document opening, then execute step S250-step S260.

[0041] Among them, not supporting dual-document opening means that only one e-book display object can be processed, and supporting dual-document opening means that two e-book display objects can be processed simultaneously.

[0042] Step S230, generate a picture according to the comparison book content, and cover the picture on the upper layer of the first screen area.

[0043] To ensure that users can freely view the content of other books within the second screen area, it is necessary to keep the second screen area corresponding to an e-book display object. Since the e-book application only supports processing one e-book display object, it is not possible to rely on the e-book display object to display the comparison book content within the first screen area. In this embodiment, a picture is generated based on the comparison book content, and the picture is overlaid on the upper layer of the first screen area, and the comparison book content is fixedly displayed in the first screen area by covering the layer.

[0044] Specifically, take a screenshot of the first screen area, and the picture obtained by the screenshot is the picture containing the comparison book content, and cover this picture on the upper layer of the first screen area; alternatively, take a screenshot of the entire first screen area and the second screen area, and make the area corresponding to the second screen area in the screenshot obtained transparent, and cover the processed picture on the top layer of the screen. The screenshot method is simple and feasible, and can ensure the accuracy of the comparison book content.

[0045] Step S240: Receive the touch operation of the user within the second screen area of the screen, and perform typesetting and rendering on the e-book display object corresponding to the second screen area, so as to display the target book content corresponding to the touch operation within the second screen area.

[0046] Among them, the second screen area is used to display the content of other books except the comparison book content, and the user can perform touch operations within the second screen area to switch the book content displayed in the second screen area.

[0047] Specifically, when the book content is displayed in split screens, an e-book display object is established according to the EPUB file of the book, and the existing e-book display object is determined as the e-book display object corresponding to the second screen area. The e-book display object corresponds to the complete EPUB file of the book. Calculate the target book content corresponding to the touch operation according to the e-book display object corresponding to the second screen area, and perform typesetting and rendering on the second e-book display object, so that the target book content corresponding to the touch operation is displayed in the second screen area.

[0048] That is to say, if the e-book application does not support dual-document opening, only one e-book display object is processed in the comparison reading mode, and the comparison book content is overlaid on the upper layer of the first screen area in the form of a picture, and the content of other books except the comparison book content is displayed in the second screen area through this e-book display object.

[0049] Further, if a trigger operation for exiting the comparison reading is received from the user, clear the picture covering the upper layer of the first screen area, and display the book content of the book in a split-screen manner through the first screen area and the second screen area. The user can execute an operation in the first screen area or the second screen area to exit the comparison reading mode. In response to the trigger operation for exiting the comparison reading by the user, clear the picture covering the upper layer of the first screen area, and restore to the normal split-screen reading mode, and display the book in a split-screen manner in the first screen area and the second screen area according to the EPUB file of the book.

[0050] In an alternative manner, if the e-book application does not support dual-document opening, the comparison reading effect can also be achieved through the following method. Specifically:

[0051] Before receiving the touch operation of the user in the second screen area of the screen, the comparison book content can be fixedly displayed in the first screen area by not refreshing the page.

[0052] After receiving the touch operation of the user in the second screen area of the screen, re-layout the e-book display object so as to layout the comparison book content and the target book content corresponding to the touch operation as adjacent reading pages; render and display the reading page containing the comparison book content obtained by re-layout in the first screen area; then the specific implementation of displaying the target book content corresponding to the touch operation in the second screen area is: render and display the reading page containing the target book content corresponding to the touch operation obtained by re-layout in the second screen area.

[0053] In this method, in the comparison reading mode, the split-screen display process of an e-book display object is still maintained through the first screen area and the second screen area. It's just that every time the user performs an operation such as turning a page in the second screen area, the book will be re-layout. Specifically, calculate the target book content to be displayed in the second screen area according to the EPUB file of the book, re-layout the comparison book content and the target book content to be displayed as two adjacent reading pages, and perform split-screen display on these two consecutive reading pages. Render and display the reading page containing the comparison book content in the first screen area, and render and display the reading page containing the target book content to be displayed in the second screen area, so as to ensure that the comparison book content is always displayed in the first screen area, and the book content displayed in the second screen area can be switched according to the user's operation, restoring the comparison reading effect of fixed comparison pages and arbitrary viewing of other pages when reading a paper book.

[0054] Step S250, layout and render the e-book display object corresponding to the first screen area, so that the comparison book content is fixedly displayed in the first screen area.

[0055] If the e - book application supports dual - opening of documents, determine the existing e - book display object as the e - book display object corresponding to the first - screen area. This existing e - book display object is the one established based on the EPUB file of the book in the previous split - screen reading mode. Perform typesetting and rendering on the e - book display object corresponding to the first - screen area so that the content of the comparison book is fixedly displayed within the first - screen area.

[0056] Step S260: Establish an e - book display object corresponding to the second - screen area according to the resource file of the book. Receive the touch operation of the user within the second - screen area of the screen, and perform typesetting and rendering on the e - book display object corresponding to the second - screen area to display the target book content corresponding to the touch operation within the second - screen area.

[0057] Establish another e - book display object corresponding to the second - screen area according to the EPUB file of the book. Calculate the target book content corresponding to the touch operation based on the e - book display object corresponding to the second - screen area, and perform typesetting and rendering on the second e - book display object so that the target book content corresponding to the touch operation is displayed in the second - screen area.

[0058] It can be seen that if the e - book application supports dual - opening of documents, then both the first - screen area and the second - screen area correspond to an e - book display object. The e - book display objects in both areas are determined according to the complete EPUB file of the book, and there is only a difference in the content rendered and displayed. The touch operation performed in the second - screen area will not affect the e - book display object corresponding to the first - screen area. Therefore, the content of the comparison book can always be fixedly displayed within the first - screen area, and the user can switch the displayed book content by performing touch operations within the second - screen area.

[0059] Further, if a trigger operation to exit the comparison reading is received, restore to the normal split - screen reading mode, and perform split - screen display of the book content through the first - screen area and the second - screen area, and display two consecutive reading pages of the book within the first - screen area and the second - screen area.

[0060] Figure 5b Shows the interface schematic diagram of the comparison reading mode in the embodiment of the present invention, as Figure 5b As shown, in the comparison reading mode, the screen includes a left split - screen area 52 and a right split - screen area 53. In the split - screen reading mode, assume that the user performs a comparison reading trigger operation within the left split - screen area. Then, fix the comparison book content currently presented within the left split - screen area, and present other book content except the comparison book content within the right split - screen area. The user can perform page - turning operations, sliding operations, page - switching operations, etc. within the right split - screen area to enable the right split - screen area to switch and display the corresponding book content.

[0061] According to the comparison reading method provided by this embodiment, in the split-screen reading mode, the book content of a book is displayed in split screens through a first screen area and a second screen area, and the first screen area and the second screen area display two consecutive reading pages of the book; moreover, implementation methods for comparison reading are provided in both cases where document dual-opening is supported and where document dual-opening is not supported; by adopting the method of this embodiment, it is possible to fixedly display the comparison book content within the first screen area, and moreover, the user can switch the book content displayed in the second screen area by performing operations within the second screen area, and can freely view other book content except the comparison book content within the second screen area, enabling comparison reading without the user having to perform complex operations, and moreover, restoring the comparison reading effect where the comparison page is fixed and other pages can be freely viewed when reading a paper book.

[0062] Figure 3 The flowchart of the comparison reading method provided by another embodiment of the present invention is shown. This method is used to switch to the comparison reading mode in the split-screen reading mode, and this method is applied to a scenario where the e-book application does not support document dual-opening, such as Figure 3 as shown, and this method includes the following steps:

[0063] Step S310, according to the resource file of the book, display the book content of the book in split screens through the first screen area and the second screen area of the screen.

[0064] Step S320, receive the comparison reading trigger operation performed by the user within the first screen area, perform a screenshot process on the first screen area, and cover the obtained screenshot on the upper layer of the first screen area.

[0065] By taking a screenshot of the first screen area, a picture containing the comparison book content is obtained, and the picture is covered on the upper layer of the first screen area, so as to fixedly display the comparison book content within the first screen area.

[0066] Step S330, receive the touch operation of the user within the second screen area of the screen, and perform typesetting and rendering on the e-book display object corresponding to the second screen area, so as to display the target book content corresponding to the touch operation within the second screen area.

[0067] The second screen area is used to display other book content except the comparison book content of the book, and moreover, the book content displayed in the second screen area switches following the touch operation of the user. The user can freely view other book content except the comparison book content of the book within the second screen area. The e-book display object corresponding to the second screen area is an e-book display object established according to the EPUB file of the book during split-screen display processing.

[0068] Step S340: Receive the first note writing operation of the user within the first screen area; determine the first book content corresponding to the first note writing operation according to the screen position information of the first note writing operation and the screen position information of the book content included in the picture; determine the first original offset information of the first book content in the book, and establish a mapping relationship between the note content written by the first note writing operation and the first original offset information.

[0069] In practical applications, users have the need to write notes, and the e-book application associates the note content written by the user with the book content so that the note content written for the book content can be reproduced later.

[0070] In this embodiment, a picture containing the compared book content is overlaid and displayed within the first screen area, and it is impossible to directly know which book content the notes are written for. Therefore, the position of the compared book content in the picture displayed on the screen is pre-recorded, and according to the screen position of the first note writing operation and the screen position of the compared book content included in the picture, the first book content targeted by the first note writing operation is determined. Then, according to the EPUB file of the book, the first original offset information of the first book content in the book (information indicating the specific position of the book content in the book, such as the fifth character position in the third chapter and the second section) is determined, and a mapping relationship between the written note content and the original offset information of the first book content is established. Thus, the note content written by the user in the first screen area in the comparison reading mode can be retained, and the note content written by the user in the comparison reading mode can be associated with the original book.

[0071] Furthermore, when receiving the first note writing operation of the user within the first screen area, the note content written by the first note writing operation is displayed in real time.

[0072] Step S350: Receive the second note writing operation of the user within the second screen area; determine the second book content corresponding to the second note writing operation and the second original offset information of the second book content in the book; establish a mapping relationship between the note content written by the second note writing operation and the second original offset information.

[0073] When the user writes note content within the second screen area, based on the position of the second note writing operation on the screen and the position of the target book content presented in the second screen area on the screen, determine the second book content targeted by the second note writing operation, and establish a mapping relationship between the note content written by the second note writing operation and the second original offset information of the second book content in its book. Similarly, determine the second original offset information of the second book content in the book according to the EPUB file of the book. Through the above method, it is possible to retain the note content written by the user for the book content presented in the second screen area in the comparison reading mode, and associate the note content written by the user in the comparison reading mode with the original book. Among them, since the second screen area is directly displayed according to the EPUB file of the book, it is convenient to quickly obtain the second book content targeted by the second note writing operation and its original offset information.

[0074] Further, when receiving the second note writing operation of the user within the second screen area, the note content written by the second note writing operation is displayed in real time.

[0075] Step S360, receive the trigger operation for the user to exit the comparison reading, clear the picture covering the upper layer of the first screen area, and display the book content of the book in a split screen manner through the first screen area and the second screen area according to the resource file of the book.

[0076] When receiving the trigger operation for the user to exit the comparison reading, clear the picture covering the first screen area, restore to the normal split screen reading mode, perform typesetting and rendering according to the EPUB file of the book, and display two consecutive book reading pages of the book through the first screen area and the second screen area.

[0077] Step S370, according to the original offset information of the book content in the book, superimpose and display the note content mapped by the original offset information on the book content.

[0078] In the normal split screen reading mode, it is necessary to superimpose and display the notes written in the previous comparison reading mode on the book content. If the original offset information of the book content to be displayed maps to note content, the note content is superimposed and displayed on the book content to be displayed.

[0079] According to the comparison reading method of this embodiment, an implementation method for writing notes in the comparison reading mode is provided. By determining the book content targeted by the note writing operation and establishing a mapping relationship between the note content and the original offset position information of the book content, it is possible to associate the note content written in the comparison reading mode with the original book, and the reproduction of the note content can be realized according to the established mapping relationship.

[0080] Figure 4The flowchart of the comparison reading method provided by another embodiment of the present invention is shown. This method is used to realize the switching to the comparison reading mode in the single-screen reading mode, as Figure 4 shown, the method includes the following steps:

[0081] Step S410, display the book content of the book in the single-screen reading area according to the resource file of the book.

[0082] Among them, in the single-screen reading mode, only one reading content display area, that is, the single-screen reading area, is included in the screen; the single-screen reading mode is further divided into a page-turning reading mode and a sliding reading mode. In the page-turning reading mode, each time the user performs a page-turning operation, the next page is switched for display; in the sliding reading mode, the content before or after the currently displayed content is displayed according to the user's sliding operation.

[0083] Step S420, receive the comparison reading trigger operation performed by the user in the single-screen reading area, obtain the book content currently presented in the single-screen reading area, and obtain the comparison book content.

[0084] During the reading process, the user performs a comparison reading trigger operation in the single-screen reading area, and determines the book content currently presented in the single-screen reading area as the comparison book content.

[0085] Step S430, divide the single-screen reading area to obtain a first screen area and a second screen area.

[0086] When switching to the comparison reading mode in the single-screen reading mode, divide the single-screen reading area to obtain a first screen area and a second screen area.

[0087] Figure 5a The interface schematic diagram in the single-screen reading mode in the embodiment of the present invention is shown. In the single-screen reading mode, each reading page of the book is displayed in the single-screen reading area 51. Figure 5b The interface schematic diagram in the comparison reading mode in the embodiment of the present invention is shown. When the user performs a comparison reading trigger operation in the single-screen reading area 51, the single-screen reading area 51 is divided into a left split-screen area 52 and a right split-screen area 53. Of course, the single-screen reading area can also be divided into an upper split-screen area and a lower split-screen area, and the present invention does not limit this.

[0088] Step S440, fixedly display the comparison book content in the first screen area of the screen.

[0089] Among them, if the e-book application does not support document dual opening, a picture containing the comparison book content is generated and overlaid on the upper layer of the first screen area. Optionally, take a screenshot of the single-screen reading area, and reduce the screenshot according to the size of the first screen area to obtain a picture containing the comparison book content.

[0090] Step S450: Receive a touch operation of the user within the second screen area of the screen, and display the target book content corresponding to the touch operation within the second screen area.

[0091] Step S460: Receive a trigger operation for the user to exit the comparison reading, and display the book content of the book through the single-screen reading area according to the resource file of the book.

[0092] The user can perform an operation within the first screen area or the second screen area to exit the comparison reading mode. In response to the trigger operation of the user to exit the comparison reading, it is restored to the single-screen reading mode, and according to the EPUB file of the book, each reading page of the book is displayed within the single-screen reading area.

[0093] According to the comparison reading method provided by this embodiment, an implementation method for switching from the single-screen reading mode to the comparison reading mode is provided.
