The embodiment of the disclosure provides a method, equipment and medium for drawing a mark line of an electronic book, which can enable a user to accurately and conveniently draw a mark line of a text of the electronic book through a stylus pen.

First, a method for drawing a mark line of an electronic book provided in an embodiment of the present disclosure is described with reference to fig. 1 to 7.

The method for drawing the mark line of the electronic book provided by the embodiment of the disclosure can be executed by an electronic device. The electronic device may include, but is not limited to, a mobile terminal such as a smart phone, a notebook computer, a PAD (PAD), an e-book reader, etc., and a stationary terminal such as a digital TV, a desktop computer, etc., among others.

Fig. 1 shows a flow chart of a method for drawing a mark line of an electronic book provided by an embodiment of the present disclosure.

As shown in fig. 1, the method for drawing a mark line of an electronic book may include the following steps.

S110, displaying a first reading page of the electronic book, wherein the first reading page comprises first electronic book texts.

In the disclosed embodiments, the electronic device may display a first reading page of the electronic book for a user to read a first electronic book text displayed within the first reading page.

That is, the first reading page may be a reading page of an electronic book currently displayed by the electronic device, and the first electronic book text may be electronic book text in the reading page of the electronic book currently displayed by the electronic device.

And S120, responding to the first handwriting stroke operation of the user on the first reading page, and determining a first pre-stroke line position of the first pre-stroke line drawn by the first handwriting stroke operation.

In the embodiment of the disclosure, during the process of displaying the first reading page of the electronic book and the first electronic book text, the electronic device may detect, in real time, a handwriting stroke line operation of a user on the reading page, when the user wants to mark some content in the first electronic book text, the first handwriting pen line operation may be performed on the first reading page, and after detecting the first handwriting pen line operation of the user on the first reading page, the electronic device may determine, in response to the first handwriting pen line operation, a first pre-drawing position of a first pre-drawing line drawn by the first handwriting pen line operation.

Alternatively, the first handwriting pen drawing operation may be an operation in which the user draws a trajectory on the first reading page with the handwriting pen. Accordingly, the first pre-scribed line is the trace that the user actually draws in the first reading page by the first stylus scribing operation.

Further, the first pre-drawing line position may include a point position of each point on the first pre-drawing line, where each point on the first pre-drawing line is a corresponding pixel point through which a trajectory actually drawn by the first stylus pen drawing operation passes, and therefore, the point position of each point is actually a pixel position of the corresponding pixel point.

Therefore, the electronic equipment can respond to the first handwriting pen drawing operation of the user on the first reading page, the pixel position of each pixel point through which the track actually drawn by the first handwriting pen drawing operation passes is obtained, the pixel position of each pixel point is used as the position of the corresponding point on the first pre-drawing line, the position of each point on the first pre-drawing line is obtained, and then the position of each point on the first pre-drawing line is used as the position of the first pre-drawing line.

Optionally, in order to accurately determine the first pre-drawing line position, the determining the first pre-drawing line position of the first pre-drawing line drawn by the first handwriting pen drawing operation in S120 may specifically include: calculating each moving position of the first handwriting stroke operation according to the initial position of the first handwriting stroke operation and each moving displacement information of the first handwriting stroke operation; the start position of the first handwriting stroke operation and each movement position of the first handwriting stroke operation are taken as a first pre-stroke position.

The initial position of the first handwriting stroke operation is the pen-down position of the first handwriting stroke operation.

Specifically, after the first handwriting pen drawing operation is dropped, if the handwriting pen remains in an un-lifted state and moves on the screen of the electronic device, that is, in the process of the user continuously inputting the first handwriting pen drawing operation, the electronic device may obtain the movement displacement information of the first handwriting pen drawing operation relative to the starting position in real time, so as to obtain each movement displacement information of the first handwriting pen drawing operation.

The information of each movement displacement of the first handwriting stroke operation comprises the actual movement direction, the actual movement length and the like of the first handwriting stroke operation, wherein the movement direction is any direction in the first reading interface.

Therefore, the electronic equipment can obtain the pixel position of each pixel point through which the track actually drawn by the first handwriting pen scribing operation passes based on the initial position of the first handwriting pen scribing operation and the movement displacement information of each first handwriting pen scribing operation, and take the pixel position of each pixel point as the point position of the corresponding point on the first pre-scribing line, so as to obtain the point position of each point on the first pre-scribing line, and further take the point position of each point on the first pre-scribing line as the first pre-scribing position.

In some embodiments of the present disclosure, as long as the electronic device displays the reading page of the electronic book and the electronic book text in the reading page, the handwriting stroke line operation of the user on the reading page is detected in real time.

In other embodiments of the present disclosure, in the process of displaying the first reading page of the electronic book and the first electronic book text, the electronic device may detect the handwriting stroke line operation of the user on the reading page in real time only in the case of the handwriting stroke line mode.

Specifically, during the process of displaying a first reading page of the electronic book and a first electronic book text, the electronic device may select a reading mode or a note mode. In the reading mode, the user can not carry out any handwritten notes and handwritten line drawing operations; in the note mode, the user may select a handwritten note mode or a handwritten line mode. In the handwriting note mode, a user can perform handwriting note operation; under the condition of the handwriting and line drawing mode, a user can click and select a pen icon displayed in the first reading page, so that the electronic equipment enters a handwriting and line drawing mode, and the user can perform handwriting and line drawing operation. If the user does not click on the pen icon displayed in the first reading page, the user may perform a finger scribe operation. Therefore, the phenomenon that the user makes wrong line drawing operation in the first reading page can be avoided, and the reading experience of the user is enhanced.

S130, responding to a first scribing determination operation of the user on the first reading page, and determining a first scribing type of the first scribing line according to the first scribing position.

In the embodiment of the disclosure, after detecting a first handwriting pen drawing operation of a user on a first reading page, the electronic device may detect a drawing determination operation of the user on the reading page in real time, after performing the first handwriting pen drawing operation on the first reading page, if the user considers that drawing is finished, the user may perform the first drawing determination operation on the first reading page, and after detecting the first drawing determination operation of the user on the first reading page, the electronic device may determine, in response to the first drawing determination operation, a first pre-drawing type to which a first pre-drawing line belongs according to a first pre-drawing position.

Optionally, the first scribing determination operation may be an operation for triggering the electronic device to scribe and label the text of the electronic book based on the first pre-scribed line.

In some embodiments, the first stroke determination operation may be a pen-up operation corresponding to the first handwriting stroke operation. That is, the user may continuously draw a continuous trace in the first reading page through the first handwriting stroke operation without lifting the pen, and if the electronic device detects that the user lifts the pen, it is determined that the first stroke determining operation is detected.

In still other embodiments, the first stroke determining operation may be a click operation of a stroke determining button displayed in the first reading page. That is, the user may continuously draw a continuous trajectory in the first reading page through the first handwriting stroke operation, and if the electronic device detects that the user clicks the stroke determining button, it is determined that the first stroke determining operation is detected.

The confirmation button may be displayed when the electronic device detects that the user lifts the pen, or may be fixedly displayed in the first reading page, which is not limited herein.

Alternatively, the first pre-scribed line type may be a straight line type or a curved line type. The straight-line type pre-scribed line can be a straight line in a strict sense and can also be a line similar to a straight line; the curve-type pre-scribed lines may be closed curves or unclosed curves.

Further, the electronic device may determine whether the first pre-scribed line is of a straight line type or a curved line type according to a position of the first pre-scribed line, that is, a point position of each point on the first pre-scribed line.

And S140, determining a first scribed text in the first e-book text according to the first pre-scribed position and the first pre-scribed type.

In the embodiment of the disclosure, after determining the first pre-drawing type to which the first pre-drawing line belongs, the electronic device may determine, according to the first pre-drawing position and the first pre-drawing type, a first drawing text to be marked by drawing in the first electronic book text. That is, the first scribed text is the e-book content that the user wants to label in the first e-book text by the first handwriting pen scribing operation.

Specifically, the electronic device may determine, according to a scribing text determination manner corresponding to the first pre-scribing type, a first scribing start character and a first scribing end character based on the first pre-scribing position, and use a first text segment containing the first scribing start character and the first scribing end character as the first scribing text.

And S150, displaying a first marking line below the first marking text.

In the embodiment of the disclosure, after determining the first ruled text to be ruled and marked, the electronic device may display a first marking line below the first ruled text.

Wherein the first marking line may be a marking line that the user wants to draw under the first lined text by the first handwriting pen-drawing operation. The marking lines can play a role in marking lines.

When the mark line is displayed, the mark line can be drawn by adopting the same refreshing mode as that of the display electronic book. If the electronic device is an ink screen device, a gray level refreshing mode can be adopted to ensure the overall display effect. Because the specific position of the marking line is determined at the moment, the local gray level refreshing mode can be directly utilized to draw in the local area, and the gray line is drawn to be used as the marking line, so that the marking line determining operation of the user can be responded quickly, and the interaction experience of the user can be improved.

In the embodiment of the disclosure, when a first reading page of an electronic book is displayed, after a first handwriting stroke operation of a user on the first reading page is received, a first pre-drawing position of a first pre-drawing line drawn by the first handwriting stroke operation is determined, after the first stroke determination operation of the user on the first reading page is received, a first pre-drawing line type to which the first pre-drawing line belongs is determined according to the first pre-drawing position, and then according to the first pre-drawing position and the first pre-drawing line type, a first stroke text is determined in the first electronic book text displayed on the first reading page, so that a first mark line is displayed below the first stroke text. Therefore, in the embodiment of the disclosure, the marking text which the user wants to mark can be accurately judged through the pre-marking position and the pre-marking type of the pre-marking line drawn by the handwriting pen, so that the user can draw the marking line conveniently and accurately through the handwriting pen, and the interaction experience of the user is improved.

In another embodiment of the present disclosure, in order to enable the handwriting stroke operation of the user to be fed back in time, the interaction experience of the user is further improved. The electronic equipment can display the track actually drawn in the first reading page by the handwriting stroke line operation when the user performs the handwriting stroke line operation.

In some embodiments of the present disclosure, after determining a first pre-drawing position of a first pre-drawing line drawn by a first handwriting stroke operation, the method for drawing a marker line of an electronic book may further include: a first pre-scribed line is displayed within the first reading page according to the first pre-scribed line position.

Specifically, the electronic device may determine, after detecting a first handwriting stroke operation on the first reading page by the user, a first pre-stroke position of a first pre-stroke line drawn by the first handwriting stroke operation in response to the first handwriting stroke operation, and display, after determining the first pre-stroke position of the first pre-stroke line, a trajectory actually drawn in the first reading page, that is, the first pre-stroke line, in the first reading page according to the first pre-stroke position.

Since the first pre-drawing position is actually the pixel position of each pixel point through which the trajectory actually drawn by the first handwriting pen drawing operation passes, the first pre-drawing can be directly displayed based on these pixel positions.

When displaying the pre-scribed line, the pre-scribed line may be drawn in a fast-swipe mode in order to more quickly respond to interaction with the user. If the electronic device is an ink screen device, the pre-scribing line can be locally and quickly brushed by adopting a second-order refreshing mode such as a DU (digital channel) mode, namely the electronic device can control the time schedule controller to control the pixel point through which the trace actually drawn by the first handwriting pen scribing operation passes to change, and specifically can control black and white ink particles to move, so that the black pre-scribing line is drawn, and the speed of drawing the pre-scribing line is greatly accelerated. At this time, the display of other areas is not affected, and the effect of the user in reading the electronic book is not affected.

For example, the user may draw an arbitrary straight line or curved line in the first reading page through the first handwriting stroke operation, and the electronic device may control the timing controller to draw the pre-stroke line corresponding to the line in the fast-brush mode.

Further, S150 may specifically include: the first pre-scribed line is replaced with displaying a first marker line under the first scribed text.

Specifically, in the case where the first pre-scribed line is displayed, after detecting the first scribe line determination operation, the electronic device may cancel displaying the first pre-scribed line and then display the first mark line under the first scribe line text in response to the first scribe line determination operation to replace the first pre-scribed line with the first mark line.

In some embodiments, the first reading page may include a first text layer and a first handwritten layer overlaid over the first text layer. The first text layer may be a text layer in the first reading page for displaying a first e-book text, and the first handwriting layer may be a handwriting layer in the first reading page for displaying a trace actually drawn by a first handwriting pen drawing operation.

At this time, the first e-book text is located in the first text layer, that is, the electronic device may display the first e-book text in the first reading page in the first text layer of the first reading page.

Further, other page contents of the first reading page may also be located in the same layer as the first ebook text, that is, other page contents of the first reading page may also be located in the first text layer, so that the user cannot operate other functions of the reading page in the handwriting stroke line mode. Or, other page contents of the first reading page may also be located on a layer different from the first ebook text, that is, other page contents of the first reading page may also be located in the first reading page layer above the first text layer, and at this time, the first reading page layer may also be covered above the first handwriting layer, so that the user may still operate other functions of the reading page in the handwriting stroke line mode.

Further, the first pre-scribed line may be located within the first handwritten pattern layer. That is, after detecting the first handwriting stroke operation of the user on the first reading page, the electronic device may display a first pre-drawing line, which is a trajectory actually drawn in the first reading page, in the first handwriting layer of the first reading page, so that the first pre-drawing line and the display of the first e-book text do not affect each other.

Further, replacing the first pre-scribed line with displaying the first marked line under the first scribed text may specifically include: canceling the display of the first pre-scribed line within the first handwritten pattern; a first marker line is displayed below the first lined text within the first text layer.

Specifically, in the case that the electronic device displays a first pre-scribed line in the first handwritten diagram, after detecting the first scribe line determination operation, the electronic device may determine, in response to the first scribe line determination operation, a first pre-scribed line type to which the first pre-scribed line belongs according to the first pre-scribed line position, and then determine a first scribed line text in the first electronic book text according to the first pre-scribed line position and the first pre-scribed line type, and after determining the first scribed line text, the electronic device may cancel displaying the first pre-scribed line in the first handwritten diagram and then display the first mark line below the first scribed line text in the first text diagram, so as to replace the first pre-scribed line with the first mark line.

In other embodiments, the first reading page may further include only the first reading page map layer, and at this time, the first ebook text, the other page contents of the first reading page, and the trace actually drawn by the first handwriting stroke operation are all located in the first reading page map layer.

Further, in the case that the electronic device displays the first pre-scribed line in the first reading page layer, after detecting the first scribing determining operation, the electronic device may determine, in response to the first scribing determining operation, a first pre-scribed line type to which the first pre-scribed line belongs according to the first pre-scribed line position, and then determine the first scribed line text in the first electronic book text according to the first pre-scribed line position and the first pre-scribed line type, and after determining the first scribed line text, the electronic device may cancel displaying the first pre-scribed line in the first reading page layer, and then display the first mark line below the first scribed line text in the first reading page layer, so as to replace the first pre-scribed line with the first mark line.

Therefore, the electronic equipment realizes the display of the track actually drawn by the handwriting pen line drawing operation in the first reading page in different page structures, so that the handwriting pen line drawing operation of a user can be fed back in time, the trace drawn by the handwriting pen can be visually felt on a screen, the error of line drawing and marking is avoided, and the interaction experience of the user is further improved.

In another embodiment of the present disclosure, in order to more accurately determine the first ruled text that the user needs to perform the ruling marking, it is now necessary to accurately determine the first pre-ruled line type to which the first pre-ruled line belongs, and further determine the first ruled text by different ruled text determination methods for different first pre-ruled lines.

First, a detailed description will be given of a specific method of determining the type of the first scribe line to which the first scribe line belongs.

In some embodiments, determining the first scribe line type to which the first scribe line belongs according to the first scribe line position in S130 may specifically include: detecting whether the first pre-scribing line has an inflection point or not according to the first pre-scribing line position; if the first pre-scribing line is detected to have an inflection point, determining that the type of the first pre-scribing line is a curve type; and if the first pre-scribed line is detected to have no inflection point, determining that the first pre-scribed line type is a straight line type.

Specifically, the electronic device may calculate whether an included angle between two straight lines connected by every three adjacent points is smaller than a preset angle threshold value based on the point positions of the points on the first pre-scribed line.

Optionally, for every three adjacent points, every two adjacent points in the drawing order may be connected into a straight line according to the drawing order to obtain two straight lines, then an included angle between the two straight lines is calculated based on the point position of each point, and then the included angle is compared with a preset angle threshold value to obtain a comparison result.

Further, if the included angle between two straight lines formed by connecting any group of three adjacent points is smaller than a preset angle threshold, determining that an inflection point exists in the first pre-scribing line, and otherwise, determining that the inflection point does not exist in the first pre-scribing line. If the electronic equipment detects that the first pre-scribing line has an inflection point, determining that the type of the first pre-scribing line is a curve type; if it is detected that the first pre-scribed line does not have an inflection point, it may be determined that the first pre-scribed line type is a straight line type.

In other embodiments, the determining, according to the first pre-scribe line position in S130, the first pre-scribe line type to which the first pre-scribe line belongs may specifically include: detecting whether the first pre-drawing line has an inflection point or not according to the movement displacement information of the first handwriting pen drawing operation; if the first pre-scribing line is detected to have an inflection point, determining that the type of the first pre-scribing line is a curve type; and if the first pre-scribing line is detected to have no inflection point, determining that the type of the first pre-scribing line is a straight line type.

Specifically, the electronic device may calculate whether a moving direction included angle between each two adjacent points is smaller than a preset angle threshold based on the moving direction in the moving displacement information.

Optionally, for each two adjacent points, a moving direction included angle between the two points may be calculated based on moving directions of the two points, and then the moving direction included angle is compared with a preset angle threshold value to obtain a comparison result.

Further, if the moving direction included angle between any two adjacent points in any group is smaller than a preset angle threshold, determining that an inflection point exists in the first pre-scribing line, otherwise, determining that the inflection point does not exist in the first pre-scribing line. If the electronic equipment detects that the first pre-scribing line has an inflection point, determining that the type of the first pre-scribing line is a curve type; if it is detected that the first pre-scribed line does not have an inflection point, it may be determined that the first pre-scribed line type is a straight line type.

Next, different ruled text determination methods for determining a first ruled text for different first pre-ruled types will be described in detail.

In some embodiments, S140 may specifically include: if the first pre-scribing type is a straight line type, determining a first scribing start character and a first scribing end character in the first electronic book text according to the first pre-scribing position; and taking a first text segment containing a first line starting character and a first line ending character as a first line text.

Specifically, if the first pre-scribed line type is a straight line type, the electronic device may determine, according to the first pre-scribed line position, a first line start character and a first line end character through which the first pre-scribed line passes in the first electronic book text, and then use a first text segment including the first line start character and the first line end character as the first line text.

If the first beginning and ending stroke words are in a text line, the first text segment includes the first beginning and ending stroke words and all words in the text line between the first beginning and ending stroke words.

If the first stroke start character and the first stroke end character are not in one text line, the first text segment comprises the first stroke start character, all characters which are positioned in the text line to which the first stroke start character belongs and are positioned behind the first stroke start character along the reading direction of the first reading page, all characters which are positioned in all text lines between the text line to which the first stroke start character belongs and the text line to which the second stroke start character belongs, the first stroke end character, and all characters which are positioned in the text line to which the first stroke end character belongs and are positioned in front of the first stroke end character along the reading direction of the first reading page.

Further, according to the first pre-scribing position, determining a first scribing start character and a first scribing end character in the first electronic book text may specifically include: determining first candidate characters corresponding to all end points of a first pre-scribed line in a first electronic book text according to the first pre-scribed line position; and determining a first line marking starting character and a first line marking ending character in each first candidate character according to the relative position relation between each first candidate character.

Specifically, the electronic device may determine, according to the first pre-drawing position, a pre-drawing start position and a pre-drawing end position of the first pre-drawing in the first reading page, then use, as first candidate texts, a text range to which the pre-drawing start position falls and a text range to which the pre-drawing end position falls, or use, as the first candidate texts, a first text passed through by the pre-drawing start position and a last text passed through by the pre-drawing end position, and then determine, according to a relative positional relationship between the first candidate texts, the first pre-drawing start text and the first pre-drawing end text in each first candidate text.

If the two first candidate characters are in one text line, the first candidate character at the front relative position in the reading direction is a first stroke start character, and the first candidate character at the back relative position in the reading direction is a first stroke end character.

If the two first candidate characters are not in one text line, the first candidate character with the first order of the text line is the first line-drawing starting character, and the first candidate character with the second order of the text line is the first line-drawing ending character.

This will be explained below with reference to fig. 2 to 4.

FIG. 2 illustrates a schematic diagram of a handwriting stroke scenario provided by an embodiment of the present disclosure.

FIG. 6 illustrates a schematic diagram of yet another handwriting stroke scenario provided by an embodiment of the present disclosure.

As shown in fig. 6, the electronic device 601 may display a first reading page 602, a first ebook text may be displayed within the first reading page 602, a user may draw a first pre-scribed line 604 within the first reading page 602, the electronic device 601 may determine a first pre-scribed text 603 within two lines of text and display a first marker line 605 below the first scribed text 603 because the first pre-scribed line 604 is an enclosed curve and the first pre-scribed line 604 passes through the two lines of text.

In still other embodiments, when the electronic device determines, according to the first pre-drawing line position, the first candidate words corresponding to the endpoints of the first pre-drawing line in the text of the first electronic book, there may also be a case where the first candidate words are not detected, for example, the first pre-drawing line does not pass through any word or any line of text, at which time, the electronic device determines that there is no first drawing line word, and therefore, the first mark line is not displayed.

FIG. 7 illustrates a schematic diagram of yet another handwriting stroke scenario provided by an embodiment of the present disclosure.

As shown in fig. 7, the electronic device 701 may display a first reading page 702, a first ebook text may be displayed in the first reading page 702, and the user may draw a first pre-scribed line 703 in the first reading page 702, and therefore, the electronic device does not display any mark-up line because the first pre-scribed line 703 does not cross any text or any line of text.

It can be seen that, in the embodiment of the present disclosure, the first ruled line can be detected and the first mark line is displayed below the first ruled line on the premise that the first pre-ruled line passes through any one of the characters or any one of the lines of the characters, so as to further avoid the situation of false ruling.

In another embodiment of the present disclosure, since a first ruled text that a user needs to perform ruling and labeling may have ruled characters, in order to further improve the user experience, it is necessary to first detect whether the first ruled text has ruled characters, and then determine how to display the first mark line according to a detection result.

In some embodiments of the present disclosure, S150 may specifically include: and detecting whether the first lined text has lined characters.

The marked characters refer to characters marked by marking lines by a user.

Specifically, after determining the first ruled text, the electronic device may first identify whether a word in the first ruled text intersects with a word in the pre-stored historical ruled text, and specifically, may identify whether a word in the first ruled text is positioned at the same position as a word in the pre-stored historical ruled text, so as to detect whether a ruled word is present in the first ruled text. Further, if the intersection exists between the characters in the first lined text and the characters in the pre-stored historical lined text, namely the characters with the same positions as the characters in the pre-stored historical lined text exist in the first lined text, it is determined that the first lined text is detected to have the lined characters, and otherwise, it is determined that the first lined text is detected not to have the lined characters.

In some embodiments, if the electronic device detects that there is a scribed character in the first scribed text, the electronic device may determine an unpainted character in the first scribed text and additionally display a first marker line below the unpainted character in the first scribed text.

The underline characters refer to characters which are never marked by underline by a user.

Specifically, if the electronic device detects that the first ruled text has ruled characters, it may identify characters in the first ruled text that do not have an intersection with the prestored historical ruled text, specifically, it may identify characters in the first ruled text that are at different positions from the prestored historical ruled text, where the identified characters are non-ruled characters.

If the electronic equipment identifies the non-scribed character, a first marking line can be additionally displayed below the non-scribed character in the first scribed text, so that the first marking line and the marking line below the scribed character in the first scribed text form a marking line; and if the electronic equipment does not recognize the unmarked characters, adding no first marking line below the first marked text.

In other embodiments, the electronic device may further detect an un-scribed character in the first scribed text if it is detected that the first scribed text has the scribed character, and if the un-scribed character is detected, additionally display a first mark line below the un-scribed character in the first scribed text, otherwise, not newly add the first mark line below all characters in the first scribed text.

In still other embodiments, after detecting whether there is a scribed text in the first scribed text, the method for drawing a mark line of the electronic book may further include: and if the first marking line text is detected to have no marked characters, additionally displaying a first marking line below all the characters of the first marking line text.

Specifically, if the electronic device detects that the first lined text does not have the lined characters, the electronic device may directly increase and display the first mark line below all the characters of the first lined text.

Therefore, in the embodiment of the disclosure, the user can not repeatedly mark the same character, the marking of the user can be not influenced by the historical marking result, the marking of the user can be fused with the historical marking result, different requirements of the user can be met, and the user experience is further improved.

In yet another embodiment of the present disclosure, the user may also implement continuous marking of e-book text within multiple reading pages, as will be described below.

Optionally, the first reading page may be a non-first reading page when marking is performed continuously.

In the case that the first reading page is a non-first reading page when marking lines continuously, S110 may specifically include: and displaying the first reading page of the electronic book in response to a second line drawing determination operation of the second reading page of the electronic book by the user.

The second reading page may be a reading page that is adjacent to the first reading page in the display order, that is, a page previous to the first reading page.

Further, the second stroke determining operation may include that the second handwriting pen stroke operation of the second reading page by the user stays in the target display area of the second reading page for a first preset time length.

Alternatively, the second handwriting pen drawing operation may be an operation in which the user draws a trajectory on the second reading page with the handwriting pen. Accordingly, the trace actually drawn in the second reading page by the user through the second handwriting stroke operation is the second pre-stroke line.

The target display area of the second reading page may be any preset display area capable of triggering the electronic device to jump to the first reading page, for example, the target display area may be a lower right corner point area or a right side bar area of the second reading page, and the like, which is not limited herein.

The first preset time period may be any time period preset according to needs, and is not limited herein.

Therefore, when the user performs the second writing pen marking operation in the second reading page, if the user wants to trigger continuous marking in the next page of the second reading page, namely the first reading page, the user can keep the writing pen in an un-lifted state and move to the target display area, and then stay in place for the first preset time after moving to the target display area, at this time, the electronic device can detect the second marking determining operation of the user on the second reading page of the electronic book, and jump to display the first reading page from the second reading page in response to the second marking determining operation.

After the electronic equipment jumps from the second reading page to the display of the first reading page, the user can realize continuous marking operation across the second reading page and the first reading page through the first handwriting pen marking operation.

In these embodiments, optionally, the method for drawing a mark line of the electronic book may further include: and displaying a second marking line under a second ruled line text in the second reading page in response to a returning operation of the user to the second reading page, the second ruled line text being determined according to a second ruled line position and a second ruled line type of a second ruled line drawn by the second ruled line determining operation.

Although the electronic device may jump from the second reading page to the display of the first reading page in response to the second stroke determining operation after detecting the second stroke determining operation by the user on the second reading page of the electronic book, at this time, the electronic device may also determine a second stroke type to which the second stroke belongs in accordance with a second stroke position of the second stroke and determine a second stroke text in the second electronic book text in accordance with the second stroke position and the second stroke type and determine that a second mark line needs to be added to the second stroke text in response to the second stroke determining operation.

Further, when the user inputs the second handwriting stroke operation on the second reading page, the electronic device may further determine, in response to the second handwriting stroke operation on the second reading page by the user, a second pre-stroke position of the second pre-stroke line drawn by the second handwriting stroke operation.

Thus, at any time during the display of the first reading page by the electronic device, if the user wants to view the scribe mark results within the second reading page, the user can return to viewing, if any.

The return operation may be a click operation on a previous page return button, or a long press operation in a designated display area, which is not limited herein. Specifically, the designated display area may be any preset display area capable of triggering the electronic device to jump to the second reading page, for example, the designated display area may be an upper left corner point area or a left side sidebar area of the first reading page, which is not limited herein.

When the user wants to view the scribing annotation result in the second reading page, the user can input a return operation for returning to the second reading page for the first reading page, and after receiving the return operation, the electronic device can display the second marking line below the second scribing text in the second reading page.

In some examples, if the user has marked a line in the first reading page before returning to the second reading page, it is determined whether the last word of the second scribed text and the first word of the first scribed text are consecutive words in reading order, e.g., the electronic device determines whether the last word of the second scribed text is the last word of the second reading page and the first word of the first scribed text is the first word of the first reading page, if so, it determines whether the last word of the second reading page and the first word of the first reading page belong to an e-book text paragraph, and if so, it determines that the last word of the second scribed text and the first word of the first scribed text are consecutive words in reading order, and further uses the second mark line and the first mark line as a new mark line, and taking the second scribing text and the first scribing text as the new scribing text corresponding to the new marking line.

Otherwise, if the last word of the second scribed text is not the last word in the second reading page, or if the first word in the first scribed text is not the first word in the first reading page, or if the last word in the second reading page and the first word in the first reading page do not belong to an e-book text paragraph, determining that the last word of the second scribed text and the first word in the first scribed text are not words in a reading sequence, and further taking the second marked line and the first marked line as two separate additional marked lines, and taking the second scribed text and the first scribed text as the additional marked text corresponding to the corresponding additional marked lines respectively.

Optionally, after the electronic device determines a second pre-scribe position of a second pre-scribe line drawn by a second handwriting pen-scribing operation, the second pre-scribe line may also be displayed according to the second pre-scribe position within the second reading page.

It should be noted that the method for determining the second pre-drawing position, the second pre-drawing type and the second drawing text and the method for displaying the second pre-drawing and the second marking line are similar to the method for determining the first pre-drawing position, the first pre-drawing type and the first drawing text and the method for displaying the first pre-drawing and the first marking line, and are not described herein again.

Therefore, the electronic equipment can provide a continuous marking and line drawing function for a user, the frequency of the user triggering the electronic equipment to enter a handwriting stroke line mode is reduced, the common marking of the user on continuous electronic book texts which are not in a reading page can be realized, and the user experience is improved.

In the case that the first reading page is a non-first reading page when marking is performed continuously, after S110, the method for drawing the mark line of the electronic book may further include: and timing the display time of the first reading page.

Specifically, after the electronic device jumps from the second reading page to the first reading page, the electronic device does not wait for the first handwriting pen line drawing operation of the user all the time, that is, the electronic device is not always in a continuous line drawing and marking state, and therefore, after the electronic device jumps from the second reading page to the display of the first reading page, the electronic device can also time the display duration of the first reading page.

Further, in response to the first handwriting stroke operation by the user on the first reading page, determining a first pre-stroke position of the first pre-stroke drawn by the first handwriting stroke operation may specifically include: and under the condition that the display duration is less than a second preset duration, responding to the first handwriting pen drawing operation, and determining a first pre-drawing position.

The second preset time period may be any time period preset according to needs, and is not limited herein.

If the display duration of the first reading page is less than the second preset duration, it indicates that the electronic device is in a continuous marking state, and may wait for a first handwriting pen marking operation of a user, at this time, if the user inputs the first handwriting pen marking operation, the electronic device may determine a first pre-marking position in response to the first handwriting pen marking operation, and implement subsequent marking.

If the display duration of the first reading page is greater than or equal to the second preset duration, it is indicated that the electronic device is no longer in the state of continuous marking, the electronic device no longer waits for the first handwriting pen marking operation of the user, and at this time, if the user inputs the first handwriting pen marking operation, the electronic device does not respond to the first handwriting pen marking operation and does not realize subsequent marking.

Therefore, after the first reading page is displayed, the electronic equipment can analyze the continuous marking and marking requirements of the user based on the display duration of the first reading page, and then automatically quit the continuous marking and marking state under the condition that the user is determined not to have the continuous marking and marking requirements any more, so that the user experience is further improved.

In yet another embodiment of the present disclosure, the electronic device further supports storage of the marking-out results for the user, as will be described in detail below.

In an embodiment of the present disclosure, the method for drawing a mark line of an electronic book may further include: and storing the new mark line of the electronic book and the new marking text corresponding to the new mark line.

Specifically, after the electronic device obtains a new mark line and a new marking text corresponding to the new mark line each time, the obtained new mark line and the new marking text corresponding to the new mark line can be automatically stored, and the stored new marking text corresponding to the new mark line becomes the pre-stored historical marking text.

The electronic device may store the new mark line and the new scribing text corresponding to the new mark line locally, or store the new mark line and the new scribing text corresponding to the new mark line in the cloud server, which is not limited herein.

Therefore, the electronic equipment can store the newly added marking line obtained by marking the line by the user each time and the newly added marking text corresponding to the newly added marking line for the user to check in the future or provide a basis for avoiding the user to repeatedly mark the marked character.
