Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are for purposes of illustration and not limitation. It should be further noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings, not all of them.
It should be noted that, for the sake of brevity, this description does not exhaust all alternative embodiments, and it should be understood by those skilled in the art after reading this description that any combination of features may constitute an alternative embodiment as long as the features are not mutually inconsistent.
The following provides a detailed description of various embodiments of the invention.
Fig. 1 is a flowchart of an information interaction management method according to an embodiment of the present invention. As shown in fig. 1, the font display enhancement method for an ink screen includes:
step S101: and acquiring a display component in a frame to be displayed, and confirming a text component and a background component in the display component.
A frame is a minimum unit of a video frame in a video movie, and corresponds to each shot on a motion picture film. A frame is a still picture and successive frames form an animation, such as a video. Each frame is taken as a still image and the display of frames in rapid succession creates the illusion of motion. A high frame rate may result in a smoother, more realistic animation. The greater the number of frames per second, the smoother the displayed motion will be. The frame rate is the frequency at which bitmap images called units of frames appear continuously on the display, and is the number of frames of a picture transmitted in 1 second time. It is also understood that the graphics processor can refresh several times Per Second, typically measured in FPS (Frames Per Second).
Each image to be displayed in the electronic ink screen is a frame to be displayed. In practical applications, for example, a home page image of a mobile phone includes a wallpaper, a return button, an exit button, and various application software on the wallpaper. Each application software has corresponding graphic mark and name, and the homepage image includes text information of various weather forecasts and text boxes for user's search. In the embodiment of the present invention, wallpaper, a return button, an exit button, graphic signs and names of respective application software, and the like on the homepage image are taken as display components. The wallpaper is a background component, and the name of the application software is a text component. When the electronic equipment displays the application-related screen, the display content can be changed in response to the operation on the application, and the plurality of display components corresponding to the changed display content form the display content of the frame to be displayed. That is, a screen including various contents visually presented in the electronic device during application interaction, can be regarded as final display contents generated by adding a plurality of display components to a blank screen in a display hierarchical order. When the frame to be displayed is specifically displayed on the electronic ink screen, the color needs to be rendered into the black and white color, the contrast between different colors in the color is obvious, but after the color is converted into the black and white color, only the gray difference is displayed in the black and white color. Therefore, in the case of a font, the font and the background are hardly distinguishable from each other in black and white, and are difficult to recognize. When a display component in a frame to be displayed is acquired, a text component and a background component in the display component need to be screened out so as to process the text component and the background component.
Step S102: and obtaining the background color and the foreground color of the display area where the text component is located and the drawing parameters of the text component.
Generally, an image can be formed by overlaying several pictures, such as a background color picture, a text picture, other control pictures, and the like. That is, the text component is typically superimposed over the background component. Specifically, one image is composed of upper and lower layers of pictures, the lower layer is wallpaper as a background picture, and the upper layer is a text component. The upper and lower layers of pictures are different in color. The color displayed on the lower layer is called background color, and the color displayed on the upper layer is called foreground color. Generally, the text displayed in the electronic ink screen after being processed may generally be composed of parameters such as theme font, text size, font style, text color and font effect. Characters with different display effects can be obtained by processing various parameters of the characters. Based on this, the present embodiment refers to the parameters such as the theme font, the character size, the font style, the character color, and the font effect as the rendering parameters. The theme font is font types such as regular script, song script, black body, microsoft elegant black and the like. The text size refers to the size ratio of the text displayed in the image. The font refers to the description of the bold, slant and regular characters. The font effect means that the character has a mark such as underlining or double-lining. The background color and the foreground color of the display area where the text component is located and the drawing parameters of the text component are obtained, so that the subsequent text component can be conveniently processed.
Step S103: and generating an enhanced text component according to the background color, the foreground color and the drawing parameters.
The specific reason for the unclear display of the characters can be analyzed through the background color, the foreground color and the drawing parameters. For example, whether the overall color tends to black or white, the difference degree between the gray values of the background color and the foreground color, and the like, under the rendering of the third-party application software. In addition, the generated enhanced text component is the display text after enhanced display based on the text in the text component. Therefore, the rendering parameters of the displayed text should be the same as the rendering parameters of the original text, so that the overall shape of the displayed text and the original text can be the same. Based on this, in this embodiment, the characters that need to be enhanced are determined according to the background color, the foreground color, and the drawing parameter, and then the characters that need to be enhanced are processed to obtain enhanced texts, where these enhanced texts are the enhanced text components.
Step S104: and drawing the display component and the enhanced text component according to the display hierarchical relationship, generating an outline in the characters in the corresponding text component after the enhanced text component is drawn, wherein the gray value difference value between the outline and the corresponding background color is greater than a preset threshold value.
Generally, the rendering order of the background component and the text component in the display component is that the background component is at the bottom layer and the text component is at the top layer. After the enhanced text component is generated, in order to display the enhanced text component, the display component and the enhanced text component need to be drawn according to the upper and lower rendering relationship between the display component and the enhanced text component. Specifically, the background component may be used as a bottom layer for rendering, the text component may be used as a middle layer for rendering, and the enhanced text component may be used as an upper layer for rendering. The finally presented display hierarchical relation comprises an enhanced text component, a text component and a background component from top to bottom in sequence. The background component can also be used as a bottom layer for drawing, then the enhanced text component is used as a middle layer for drawing, and the text component is used as an upper layer for drawing. The display hierarchy that is finally presented is, from top to bottom, a text component, an enhanced text component, and a background component.
After the display component and the enhanced text component are drawn, because the background component, the display component and the enhanced text component are overlapped together, and the gray values of the background component, the display component and the enhanced text component are relatively close, there may be characters that are difficult to distinguish from the corresponding text component in the background component and the enhanced text component. Specifically, after the display component and the enhanced text component are drawn, the outline of the characters in the text component corresponding to the enhanced text component can be generated to enhance the character display, so that the overall outline of the characters can be displayed under the superposition of multiple layers of pictures. Specifically, in the process of generating the contour, the overall contour of the text is identified first, and then the gray value of the contour is adjusted to ensure that the gray value difference between the contour and the corresponding background color is greater than a preset threshold value, so as to realize enhanced display of the contour.
In a specific implementation process, step S103 may be implemented by step S1031 to step S1033, where step S1031 to step S1033 include:
step S1031: and confirming the corresponding gray difference according to the background color and the foreground color.
Step S1032: and determining the text component with the gray difference within the preset enhancement range as the component to be enhanced.
Step S1033: amplifying the font width of the component to be enhanced according to a preset standard to obtain the font width of the corresponding enhanced text component, taking the target contrast color as the drawing color of the corresponding enhanced text component, taking other drawing parameters in the component to be enhanced as the corresponding drawing parameters of the corresponding enhanced text component, and setting the gray difference between the target contrast color and the corresponding background color as a preset high-contrast reference value.
The gray value is a gray color that appears at different levels on a captured black-and-white photograph or a black-and-white image reproduced by a television receiver, because the colors and the brightnesses of the respective points in the scene are different. The logarithmic relationship between white and black is divided into several levels, i.e. grey levels. The gray levels typically range from 0 to 255, 255 for white and 0 for black. Black and white pictures are also called gray level images, and have wide application in the fields of medicine and image recognition. The display in the electronic ink screen is generally black and white, and the shade of the picture color presented by different gray values can be correspondingly different. Correspondingly, background and foreground colors of different gray values may appear differently gray. Therefore, the present embodiment can confirm the gray difference between the two gray values according to the gray value of the background color and the gray value of the foreground color. When the gray difference meets the preset enhancement range, the gray difference between the background color and the foreground color is smaller and is difficult to distinguish visually, so that the text component with the gray difference within the preset enhancement range can be determined as the component to be enhanced.
Before processing the component to be enhanced, a preset standard for correspondingly adjusting the component to be enhanced needs to be acquired. The preset criteria may include the width of the text that needs to be expanded. And then, amplifying the text width of the component to be enhanced according to a preset standard, and taking the amplified text as an enhanced text component. Specifically, in the drawing process, the entire width of the drawn text is expanded. It is to be understood that the text is shown in bold. As shown in fig. 2, the text "seven" of the enhanced text component 130 is significantly wider than the overall width of the text "seven" of the text component 120. Specifically, in order to make the overall shape of the text "seven" of the enhanced text component 130 the same as that of the text "seven" in the text component 120, it is necessary to set the corresponding drawing parameters of the corresponding enhanced text component 130 according to the other drawing parameters of the component to be enhanced. That is, the rendering parameters of the text in the text component 120, such as the subject font, the text size, the font style, the text color, and the font effect, are the same as the rendering parameters of the text in the enhanced text component 130. For example, the text "seven" in the text component 120 has a theme font of song font, a character size of four, a glyph of oblique, a color of black, no font effect. Then correspondingly, the theme font of the text "seven" in the enhanced text component 130 is sons font, the text size is four, the font is oblique, the color is black, and there is no font effect. In order to distinguish the color of the component to be enhanced from the background color, the gray difference between the target contrast color and the corresponding background color may be used as a preset high contrast reference value. That is, the grayscale difference of the contrast color of the enhanced text component 130 from the background color satisfies a certain high contrast reference value. Specifically, if the background color is black, the contrasting color of the enhanced text component 130 is white, and if the background color is white, the contrasting color of the enhanced text component 130 is black. As shown in fig. 2, the background color is white, and the text "seven" in the enhanced text component 130 is black. The display of the text "seven" in the enhanced text component 130 is made clearer in contrast to black and white.
In a specific implementation process, step S104 may include:
step S1041: and drawing the background component, the enhanced text component and the text component in sequence according to the display hierarchical relation.
After the enhanced text component 130 is generated, the background component 110, the enhanced text component 130, and the text component 120 need to be redrawn, and the background component 110, the enhanced text component 130, and the text component 120 are overlaid one on top of the other. The superposition of different components is a hierarchical relationship. And superposing the components according to different hierarchical relationships, so that the finally presented display effect is different. Based on this, the present embodiment can draw components in order according to the display hierarchical relationship. It is to be appreciated that the background component 110 is the lowest layer of the plurality of levels regardless of how the hierarchical relationship of the enhanced text component 130 and the text component 120 is transformed. In order to embody the sense of hierarchy between the enhanced text component 130 and the text component 120 to further enhance the font display enhancement effect, the embodiment may draw the background component 110, the enhanced text component 130, and the text component 120 in sequence according to the display hierarchical relationship. The display effect after drawing is relatively clear, and as shown in fig. 5, the display effect can clearly display the outline of the text "seven". Of course, if the display enhanced text component 130 is superimposed over the text component 120, the text color can also be distinguished from the background color, as shown in FIG. 6. Since the overall width of the text "seven" in the enhanced text component 130 is greater than the width of the text "seven" in the text component 120, even if the enhanced text component 130 is drawn above the text component 120 at the level where the enhanced text component 130 is located, the text component 120 is occluded by the enhanced text component 130, and the text "seven" in the enhanced text component that is finally presented is relatively clear. Moreover, the embodiment also needs to adjust the contrast color of the enhanced text component 130 to adjust the gray difference between the enhanced text component 130 and the background color. If the background color is white, correspondingly, the text "seven" in the enhanced text component 130 is black. The display effect of the text "seven" in the enhanced text component 130 is made more noticeable in contrast to black and white. In the prior art, the original text is generally enlarged and bolded, or a new text is redrawn. However, enlarging, thickening, etc. the original text results in image distortion and unclear text display. And redrawing the new text to be overlaid on the original text without considering the gray difference between the contrast color and the background color of the new text. Therefore, the final character effect is not ideal, and the specific effect is shown in fig. 4. Obviously, the whole display effect after the font display enhancement is obviously clearer than that of the prior art, and the reading of the user is facilitated, so that the reading experience of the user is improved.
In a specific implementation process, step S103 may be implemented by step S1034 to step S1036, where the step S1034 to step S1036 include:
step S1034: and confirming the corresponding gray difference according to the background color and the foreground color.
Step S1035: and determining the text component with the gray difference within the preset enhancement range as the component to be enhanced.
Step S1036: amplifying the font width of the component to be enhanced according to a preset standard to be used as the font width of the corresponding enhanced text component, setting the font effect of the enhanced text component to be hollow, taking the target contrast color as the drawing color of the corresponding enhanced text component, taking other drawing parameters in the component to be enhanced as the corresponding drawing parameters of the corresponding enhanced text component, enabling the hollow part to be overlapped with the characters in the corresponding component to be enhanced, and enabling the gray difference between the target contrast color and the corresponding background color to be a preset high-contrast reference value.
It is understood that step S1034 is the same as the specific discussion regarding step S1031, and step S1035 is the same as the specific discussion regarding step S1032. Therefore, it is not described herein in detail.
Before processing the component to be enhanced, a preset standard for correspondingly adjusting the component to be enhanced needs to be acquired. The preset criteria may include the width of the text that needs to be expanded. Then, the text width of the component to be enhanced is enlarged according to the preset standard, and the enlarged text is used as the enhanced text component 130. Specifically, in the drawing process, the entire width of the drawn text is expanded. It is understood that the text is shown bold. In addition, the font effect of the enhanced text component 130 in this embodiment is set to hollow. Specifically, the outline of the hole can be adapted to the text in the text component 120. As shown in fig. 3, the text "seven" in the enhanced text component 130 is significantly larger than the overall width of the text "seven" in the text component 120, and the text "seven" in the enhanced text component 130 is hollowed out. The outline of the hollow fits the text "seven" in the text component 120. That is, the text "seven" in the text component 120 may just fill the hollowed-out position of the text "seven" in the enhanced text component 130. Specifically, in order to make the overall shape of the text "seven" in the enhanced text component 130 the same as that of the text "seven" in the text component 120, it is necessary to set the corresponding drawing parameters of the corresponding enhanced text component 130 according to the other drawing parameters of the component to be enhanced. That is, the rendering parameters of the text in the text component 120, such as the subject font, the text size, the font style, the text color, and the font effect, are the same as the rendering parameters of the text in the enhanced text component 130. For example, the text "seven" in the text component 120 has a theme font of song font, a character size of four, a glyph of oblique, a color of black, no font effect. Correspondingly, the text "seven" in the enhanced text component 130 has a theme font of song font, a character size of four, a font of slant, a color of black, and a font effect of hollow. Obviously, the seven without font effect just fills the hollow seven. In order to distinguish the color of the component to be enhanced from the background color, the gray difference between the target contrast color and the corresponding background color can be used as a preset high contrast reference value. That is, the grayscale difference of the contrast color of the enhanced text component 130 from the background color satisfies a certain high contrast reference value. Specifically, if the background color is black, the contrasting color of the enhanced text component 130 is white, and if the background color is white, the contrasting color of the enhanced text component 130 is black. As shown in fig. 3, the background color is white, and the text "seven" in the enhanced text component 130 is black. The display of the text "seven" in the enhanced text component 130 is made clearer in comparison to black and white.
In a specific implementation process, step S104 may include:
step S1042: and sequentially drawing the background component, the text component and the enhanced text component according to the display hierarchical relation.
As in the above discussion about step S1041, in this embodiment, after the enhanced text component 130 is generated, the background component 110, the enhanced text component 130, and the text component 120 also need to be redrawn, and the background component 110, the enhanced text component 130, and the text component 120 are overlaid together. The overlapping relationship of different components is a hierarchical relationship. And the components are overlapped according to different hierarchical relations, so that the finally presented display effect is different. Based on this, the present embodiment can draw components in order according to the display hierarchical relationship. It is to be appreciated that the background component 110 is the lowest layer of the plurality of levels regardless of how the hierarchical relationship of the enhanced text component 130 and the text component 120 is transformed. Since the overall width of the text in the enhanced text component 130 is greater than the width of the text in the text component 120, the font effect in the enhanced text component 130 is hollowed out. That is, when the text component 120 and the enhanced text component 130 are superimposed, the text in the text component 120 just fills the hollow in the enhanced text component 130. Therefore, no matter whether the enhanced text component 130 is overlaid on top of the text component 120 or the text component 120 is overlaid on top of the enhanced text component 130, the text between the two will not be occluded from each other. That is, whatever rendering method is used, the rendering effect of the final presentation is that the text "seven" in the enhanced text component 130 and the text "seven" in the text component 120 can be displayed. Based on this, the present embodiment may sequentially draw the background component 110, the text component 120, and the enhanced text component 130 according to the display hierarchical relationship, and may also sequentially draw the background component 110, the enhanced text component 130, and the text component 120. The display effect of both rendering modes can clearly display the outline of the text "seven", specifically, as shown in fig. 5. If the background color is white, correspondingly, the text "seven" in the enhanced text component 130 is black. The display effect of the text "seven" in the enhanced text component 130 is made more noticeable in contrast to black and white.
In a specific implementation process, step S1031 or step S1034 may be implemented by steps S301 to S303, where steps S301 to S303 include:
step S301: and counting the gray value of the pixel point in the background color, and determining a first gray value corresponding to the background color according to the distribution state of the gray value in the gray interval.
Step S302: and determining a second gray value corresponding to the foreground color according to the drawing parameters.
Step S303: and confirming the corresponding gray difference according to the first gray value and the second gray value.
After the background color is rendered from color to black and white, black and white images with different gray scales are presented. The gray scale in the black-and-white image can be divided and the gray scale values of all the pixel points can be counted by analyzing the black-and-white image. The gray intervals in which the gray values corresponding to each pixel point are located are different, and the density of the pixel points in each gray interval can be obtained by counting the distribution state of the gray values of each pixel point in the gray intervals. And sequencing the density of the pixel points in each gray interval to determine the gray interval with the densest pixel points, and taking the closest gray value in the gray interval with the densest pixel points as a first gray value corresponding to the background color.
The foreground color refers to the color of the area where the text is located, and the drawing parameters of the text generally include a theme font, a character size, a font style, a character color, a font effect and the like. The gray values of the pixel points forming the text and the distribution condition of the pixel points can be determined according to the drawing parameters, and the second gray value corresponding to the foreground color can be determined by counting the gray values of all the pixel points in the foreground color.
And after the first gray value and the second gray value are confirmed, the gray difference between the background color and the foreground color can be obtained by making a difference between the first gray value and the second gray value.
In a specific implementation process, the method may further include:
step S105: and receiving a screenshot instruction.
Step S106: and responding to the screenshot instruction, and storing the image generated according to the display component corresponding to the current display frame, or storing the image generated according to the display component corresponding to the current display frame and the enhanced text component.
An image enhanced by font display is presented in the electronic ink screen, and the image is obtained by three levels of superposition display of the background component 110, the text component 120 and the enhanced text component 130, namely superposition of the display component and the enhanced text component 130. While performing font display enhancement processing to display a corresponding frame, all display components (including processed enhanced display components) corresponding to the frame may be buffered. In the process of displaying one frame of image, when a screenshot instruction is received, generating a picture according to the cached display component for storage. It is to be appreciated that the image saved at this time can be either the image generated by the original display component or the image generated by the display component and enhanced text component 130. The font in the original image needs to be subjected to display enhancement processing on the electronic ink screen so as to enable the image to be displayed clearly. However, in a common display screen, the display effect of the original image is clearer, and even if the font in the original image is not enhanced, the reading of the user is not affected. Therefore, in this embodiment, when the screenshot instruction is received, the image generated by the display component corresponding to the current display frame, that is, the original image that has not undergone the font display enhancement processing may be saved after the screenshot instruction is responded. If the saved original image needs to be displayed on other electronic ink screens, the font display enhancement method described in the above embodiment may be adopted again to process the original image. Of course, when the screenshot command is received, the image generated according to the display component and the enhanced text component corresponding to the current display frame may also be saved after the screenshot command is responded, that is, the font displays the enhanced image. The image is not only suitable for a common display screen, but also suitable for an electronic ink screen, and can be directly displayed on the electronic ink screen without additional processing.
Certainly, after a new frame is displayed, the display component corresponding to the buffer memory of the previous frame is correspondingly deleted, and the display component corresponding to the new frame is buffered, so that the data in the buffer memory area is prevented from continuously increasing, and meanwhile, the new frame can be ensured to complete the screenshot according to the description above.
In a specific implementation process, before step S101, the method further includes:
step S100: the activation of the display enhancement function is confirmed.
Some of the images displayed on the electronic ink screen may require font display enhancement processing to be clearly displayed, and some may be clearly displayed without additional processing. The display enhancement function may be set to automatically turn on for the convenience of the user's reading. Of course, the present embodiment may also set the display enhancement function to be manually turned on. However, whether the display enhancement function is set to be manually turned on or automatically turned on, it is necessary to confirm the turning on of the display enhancement function when font display enhancement processing is performed. Specifically, the font display function can be represented by a boolean variable. The boolean variable may include two logical state variables, including true and false values, respectively. If a boolean variable is used, the integer value 1 or 0 may be assigned depending on the truth of the variable value. To convert an integer variable into a boolean variable, if the integer value is 0, its boolean value is false; otherwise, if the integer value is not 0, then its boolean value is true. Boolean variables are typically used as flags at runtime, such as performing logic tests to change program flow. In this embodiment, a boolean variable representing the display enhancement function may be read, and when the value of the boolean variable is true, it is determined that the font display enhancement function is turned on, and when the value of the boolean variable is false, it is determined that the font display enhancement function is turned off.
