As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0054] Embodiment One

[0055] The first embodiment of the present application provides an electronic book editing method, which is applied to the scenario of text reading, i.e. the electronic book reading interface does not contain illustrations, tables and other parts except for text. Please refer to FIG. 1, which is a schematic diagram of an electronic book reading interface. Figure 1 An implementation flowchart of an electronic book editing method is shown in FIG. 2, which specifically includes steps S01 to S06.

[0056] In step S01, the historical electronic book screenshots of a user are acquired, wherein the historical electronic book screenshots at least contain characters arranged in a preset layout format.

[0057] Specifically, the historical electronic book screenshots are screenshots of layout modes that the user likes, which can be screenshots on a computer, screenshots on a mobile phone, screenshots on an electronic book reader, etc. The characters in the screenshots are mainly composed of text and symbols. It should be noted that the text includes common reading text such as Chinese and English.

[0058] The user can save the electronic book screenshot without knowing or remembering the layout parameters, and when reading the electronic book on another terminal, the layout parameters obtained by analyzing the electronic book screenshot can be imported into the terminal, so as to finally ensure the reading experience of the user.

[0059] In step S02, the target electronic book screenshot is matched from the historical electronic book screenshots according to the size of the current electronic book screenshot and the character information.

[0060] It should be noted that the size of the current electronic book screenshot and the character information including at least the text type are obtained. It can be understood that the resolution can be understood from the size of the current electronic book screenshot, and the screenshots with consistent resolution or within a certain deviation range can better meet the user's needs. In addition, the text type refers to common reading texts such as Chinese and English. It can be understood that Chinese and English have obvious differences in font, and can be matched separately.

[0061] It is determined whether there is a screenshot with the same size as the current electronic book screenshot in the historical electronic book screenshots.

[0062] If it is determined that there is a screenshot with the same size as the current electronic book screenshot in the historical electronic book screenshots, it is determined whether the text type in the screenshot with the same size as the current electronic book screenshot is consistent with the text type in the historical electronic book screenshots.

[0063] If it is determined that the text type in the screenshot with the same size as the current electronic book screenshot is consistent with the text type in the historical electronic book screenshots, the corresponding screenshot is determined as the target electronic book screenshot. For example, the screenshot with the same size and the text type of Chinese is determined as the target electronic book screenshot.

[0064] In step S03, the character region of the target electronic book screenshot is located, and at least two rows of characters in the target electronic book screenshot are extracted according to the character region.

[0065] In the embodiment of the application, a rectangular coordinate system of the target electronic book screenshot is established, and the pixel value of each pixel point in the screenshot is obtained. Specifically, the rectangular coordinate system can be established with the lower left corner of the target electronic book screenshot as the origin, and each pixel point as a coordinate point.

[0066] According to the preset pixel value range and the pixel value difference of adjacent pixel points, the coordinate positions of the first target pixel points representing characters are determined. It can be understood that in general cases, it is white background and black text, and the pixel points with black pixel values can be marked as first target pixel points. In addition, if it is not in the form of white background and black text, the first target pixel points can also be determined by the pixel value difference of adjacent pixel points, that is, when the pixel value difference of adjacent pixel points is greater than a threshold value.

[0067] According to the coordinate position of each first target pixel point, polar coordinate points in the horizontal axis direction and the vertical axis direction are determined, wherein the polar coordinate points at least include coordinate points in the up, down, left and right four directions;

[0068] According to the polar coordinate points, the character region is located, and at least two lines of characters in the character region are recognized and extracted. Specifically, according to the polar coordinate points, a rectangular frame is drawn, and the area of the rectangular frame is the character region. Since the characters in the character region are arranged in a certain regularity, for example, the line spacing can be determined according to the periodic interval of the first target pixel point in the vertical axis direction, and at least two lines of characters are extracted.

[0069] It should be noted that the extracted at least two lines of characters include punctuation marks, and the punctuation marks are at least a period.

[0070] In step S04, the at least two lines of characters extracted from the target electronic book screenshot are analyzed to determine the text layout information.

[0071] Specifically, according to the at least two lines of characters in the target electronic book screenshot, the number of characters in a line and the interval distance between two lines of characters are determined. It can be understood that the outline of a character is determined according to the pixel value difference of adjacent pixel points. Taking the first target pixel point representing the character as an example, when the pixel difference between the first target pixel point and the pixel point outside is greater than a threshold value, and the pixel difference between the first target pixel point and the pixel point inside is close to 0, the first target pixel point can be regarded as a pixel point on the outline. By counting the coordinate positions of all the pixel points on the outline, the periodic interval of the pixel points representing the outline in the horizontal axis direction can be determined, and the number of characters in a line and the interval distance between two lines of characters can be obtained.

[0072] According to the length of the character region in the target electronic book screenshot, the number of characters in a line and the interval distance between two lines of characters, the pixel point region of a single character is determined. It should be noted that the pixel point region of a single character is not a rectangular region formed by the pixel points of a single character outline, but a blank target rectangular region when the character is to be input. The size of the blank target rectangular region is related to the font. After the character is input, the character is located at a predetermined position of the target rectangular region, for example, in the middle position of the target rectangular region when Chinese is input, or in the lower left corner position or the middle position of the target rectangular region when a period is input. It can be understood that different fonts have different period styles, which may be different relative positions or different outlines of the period. For example, when Chinese characters are mainly used, the recognition of the period can at least distinguish between Songti, Fanti, Black Body, Kaishu, and other fonts.

[0073] In each pixel point region, a target pixel point region with a period is searched, that is, a circular pixel point region is searched, and a second target pixel point corresponding to the period is obtained. According to the size of the target pixel point region and the distribution of the second target pixel point, a font is determined. Specifically, the length and width of the target pixel point region, that is, the length and width of the target rectangular region, are obtained. It should be noted that the length in the horizontal coordinate direction of the target rectangular region is regarded as the length, and the length in the vertical coordinate direction of the target rectangular region is regarded as the width, or the length in the horizontal coordinate direction of the target rectangular region is regarded as the width, and the length in the vertical coordinate direction of the target rectangular region is regarded as the length. The length-width ratio is calculated, and the corresponding first font is matched according to the length-width ratio. It can be understood that the size of the target rectangular region can reflect a part of the font type.

[0074] The coordinate position of the second target pixel point is obtained, and the coordinate position of the center point of the period is determined according to the coordinate position of the second target pixel point.

[0075] The distance from the center point coordinate position to the preset boundary of the target pixel point region is calculated. For example, the distance from the center point coordinate position to the left boundary of the target pixel point region and the distance from the center point coordinate position to the lower boundary of the target pixel point region are calculated respectively, and the distance ratio is calculated. According to the distance ratio, a second font is selected from the first font.

[0076] According to the coordinate position of the second target pixel point, the number of all pixel points in the period region, that is, the number of all pixel points in the circular region, is determined, and the number ratio of the number of the second target pixel point representing the period to the number of all pixel points in the period region is calculated. It can be understood that after analyzing the position of the period relative to the target pixel point region, the period may be thickened or thinned according to the different fonts. The change in the pixel points is finally reflected in the change in the number of pixel points. Therefore, according to the number ratio of the pixel points, the target font type is determined.

[0077] According to the number ratio, a third font is selected from the second font to determine the final font.

[0078] According to the size of the pixel point region of a single character, the number of characters in a line of characters, and the font, the font size is determined. When the size of the pixel point region of a single character, the number of characters in a line of characters, and the font are determined, the influence of the screenshot scaling on the font size can be excluded, and the real font size is determined.

[0079] In step S05, color layout information is determined according to the target electronic book screenshot.

[0080] The color of the character and the color of the background are extracted to determine the color layout information, specifically, the color can be determined according to the pixel value of the pixel point representing the character, and the pixel value of the remaining part is determined as the pixel value of the background color after the color of the character is determined.

[0081] In step S06, the current electronic book is laid out according to the text layout information and the color layout information to obtain a layout result, so as to complete the editing of the electronic book.

[0082] In conclusion, the electronic book editing method provided by the embodiment of the present application can obtain the historical electronic book screenshots of the user, and the historical electronic book screenshots at least contain characters arranged in a preset layout format; the target electronic book screenshot in the historical electronic book screenshots is matched according to the size and character information of the current electronic book screenshot; the character region in the target electronic book screenshot is located, and at least two rows of characters in the target electronic book screenshot are extracted according to the character region; the at least two rows of characters extracted from the target electronic book screenshot are analyzed to determine the text layout information; the color layout information is determined according to the target electronic book screenshot; and the current electronic book is laid out according to the text layout information and the color layout information to obtain a layout result, specifically, the user can make the currently read electronic book present a state meeting the requirements without remembering the layout parameters meeting the reading habits of the user, so as to improve the reading experience of the user.
