In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, shall fall within the protection scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Moreover, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Example 1
In accordance with an embodiment of the present invention, there is provided an embodiment of an image presentation method, it should be noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system such as a set of computer executable instructions, and that while a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than here.
In addition, it should be noted that an electronic device with a display screen may be used as the execution subject of this embodiment, where the electronic device may be, but is not limited to, a computer, a mobile phone, a tablet, an electronic whiteboard device, and the like.
Fig. 1 is a flowchart of an image presentation method according to an embodiment of the present invention, as shown in fig. 1, the method including the steps of:
step S102, obtaining an original image to be displayed in application and a preset texture image.
In step S102, the preset texture image is an image with a textured transparent effect, that is, the preset texture image contains the texture that the user needs to display in the original image, but the background is transparent color.
Optionally, the user may obtain the texture image from a local memory of the electronic device through the electronic device, or obtain the texture image through the internet. In the process of starting the application, the electronic device obtains an image (i.e., an original image) displayed after the application is started, and obtains a texture image preset by a user.
And step S104, overlapping the original image and the texture image to obtain an overlapped image.
Optionally, in step S104, the electronic device may employ an existing image overlay algorithm to overlay the original image and the texture image. It should be noted that, since the texture image is an image with a transparent effect, after the original image and the texture image are superimposed, the content (for example, characters, pictures, etc.) in the original image is not blocked.
And step S106, carrying out gray level adjustment on the superposed image to obtain a target image.
It should be noted that although the superposition of the original image and the texture image does not block the content (e.g., text, picture, etc.) in the original image, the gray value of the low gray portion in the original image is increased, for example, the text in the original image is black, and the color of the text in the superposed image obtained after the original image and the texture image are superposed becomes lighter, which affects the reading effect. In order to reduce the influence of the superposition of the original image and the texture image on the gray value of the low gray part in the original image, the electronic equipment also performs gray adjustment on the superposed image so as to enable the gray value of the low gray part in the adjusted image to be the same as that of the original image, thereby ensuring the reading experience of a user.
And step S108, displaying the target image.
After the target image is obtained through the image superimposition in step S104 and the gray scale adjustment in step S106, after the application is started, the electronic device can not only display the texture effect, but also ensure that the low gray scale portion in the original image can be displayed clearly.
Based on the solutions defined in steps S102 to S108, it can be known that, in the embodiment of the present invention, after an original image to be displayed and a preset texture image in an application are obtained by combining image superposition and image processing, a superposed image is obtained by superposing the original image and the texture image, a target image is obtained by performing gray scale adjustment on the superposed image, and the target image is displayed.
It is easy to note that in the above process, the image obtained by superimposing the original image and the texture image is used as the image to be displayed by the application, and the process can make the image displayed by the application have the texture without modifying the display content. In addition, the process can be realized only by image superposition, so that the process does not need to set all the applications one by a user, and when the application runs, the current image of the application and the texture image are superposed. Finally, in order to minimize the difference between the display of the content of the superposed image and the display of the content of the original image, the method and the device also automatically adjust the gray level of the superposed image, so that the definition of the display of the image content can be ensured on the basis of texture of the adjusted target image, and the use experience of a user is improved.
Therefore, the scheme provided by the application achieves the purpose of texture display of the image in the application, so that the technical effect of simplifying the operation steps of the texture display of the image is achieved, and the technical problem that in the prior art, the original image needs to be modified when the texture display of the image in the application is carried out, and the operation is complicated is solved.
In an optional embodiment, after acquiring an original image to be displayed in an application and a preset texture image, the electronic device further performs scaling processing on the original image to obtain a scaled original image, and then performs color space conversion on the scaled original image to obtain a processed original image.
In order to increase the processing speed of image processing, the electronic device performs scaling processing on the original image after acquiring the original image and the texture image. In addition, in the above process, the original image is an image in RBG space, and the image needs to be converted into YUV space to be processed, so after the original image and the texture image are obtained, the electronic device needs to perform color space conversion on the original image, that is, the original image is converted from RBG space into YUV space, wherein the conversion between RBG space and YUV space can be implemented by using the following conversion formula:
Y＝0.299R+0.587G+0.114B
U＝-0.147R-0.289G+0.436B
V＝0.615R-0.515G-0.100B
R＝Y+1.14V
G＝Y-0.39U-0.58V
B＝Y+2.03U
in an optional embodiment, after the original image and the texture image are obtained, the electronic device superimposes the original image and the texture image, and then performs gray scale adjustment on the superimposed image, where the electronic device may perform gray scale adjustment by using preset data (i.e., in a first manner), and may also perform gray scale adjustment adaptively through the original image (i.e., in a second manner).
Optionally, in the first mode, the electronic device first obtains grayscale information corresponding to the texture image, and performs grayscale adjustment on the superimposed image according to the grayscale information to obtain the target image. In the process of adjusting the gray scale of the superposed image according to the gray scale information to obtain the target image, the electronic equipment determines data to be adjusted according to the gray scale information, then determines an image area of which the gray scale value is lower than a preset gray scale value in the superposed image, and finally adjusts the gray scale value of the image area according to the data to be adjusted to obtain the target image. In the process of adjusting the gray value of the image area according to the data to be adjusted to obtain the target image, the electronic device determines first gray data corresponding to the image area from the data to be adjusted, and sets the first gray data as the gray value of the image area to obtain the target image.
Optionally, fig. 2 shows a schematic flow diagram of an optional image processing, as can be seen from fig. 2, in the first mode, after entering the paper image mode, the electronic device obtains the texture image from the local memory, calls preset GAMMA data (i.e., data to be adjusted), then uses the GAMMA data to perform gray level adjustment on the image obtained by superimposing the texture image and the original image, and finally, the electronic device outputs the adjusted image.
Specifically, a user first sets an image with a texture transparency effect as a texture image, and then debugs a set of GAMMA data (i.e., data to be adjusted) capable of reducing the gray level of the superimposed image increased compared with the original image according to the gray level difference between the superimposed image of the texture image and the original image. When the user selects the application to display with the paper image effect, the electronic equipment pops up the preset texture image as a menu and superposes the menu on the original image, and at the moment, the superposed image has a layer of paper texture. However, the image of the low gray part in the superimposed image (i.e. the image area with the gray value lower than the preset gray value) will turn white, for example, the gray value of the black font in the image is increased after the texture is superimposed again, thereby affecting the overall effect. At the moment, the electronic equipment calls a set of set GAMMA data (namely data to be adjusted) to reduce the dark field brightness, and the influence on the image of the low gray part is reduced as much as possible, so that the display content of the superposed image can achieve the paper image effect.
Optionally, fig. 3 shows a schematic flow diagram of an optional signal processing, as can be seen from fig. 3, the electronic device stores a designed texture image with a texture transparency effect in the Flash storage module, and when the user selects an application to display with a paper image effect, the electronic device starts a paper image output function, decompresses the transparent texture image with the paper image and outputs the decompressed texture image to the GPU video storage module, and then outputs the decompressed texture image. Meanwhile, the signal processing and outputting part acquires an original image (i.e., signal input in fig. 3), performs image scaling on the original image, performs color space conversion, and performs image processing, for example, processing of image brightness, contrast, GAMMA data, and the like, wherein the image processing and outputting part calls different image data according to whether the electronic device opens a paper image effect function. Finally, the electronic device outputs the image.
In an optional embodiment, in the second mode, the electronic device obtains a color value of the original image, and performs gray scale adjustment on the superimposed image according to the color value to obtain the target image. In the process of adjusting the gray level of the superposed image according to the color value to obtain the target image, the electronic equipment analyzes the color value to determine the gray level difference value between the superposed image and the original image, then determines the image area of which the gray level value is lower than the preset gray level value in the superposed image, and adjusts the gray level value of the image area according to the gray level difference value to obtain the target image. And the electronic equipment determines second gray data corresponding to the image area from the gray difference value in the process of adjusting the gray value of the image area according to the gray difference value to obtain the target image, and sets the second gray data as the gray value of the image area to obtain the target image.
Optionally, fig. 4 shows a schematic flow diagram of an optional image processing, as can be seen from fig. 4, in the second mode, after the electronic device enters the paper image mode, the electronic device obtains the texture image from the local memory, identifies the RGB values of the original image, then, after the texture image and the original image are superimposed, analyzes the difference between the grayscale value of the superimposed image and the grayscale value of the original image, adjusts the grayscale value of the superimposed image according to the difference, and finally, the electronic device outputs the adjusted image.
Specifically, a user firstly sets an image with a texture transparency effect as a texture image, when the user selects an application to display with a paper image effect, the electronic device identifies an RGB value of an original image, simultaneously pops the texture image as a menu to be superimposed on the original image, analyzes the RGB value of the superimposed image to confirm an increase value of the gray level of a low gray level region of the superimposed image relative to the gray level of the low gray level region of the original image, then adjusts the gray level of the low gray level region of the superimposed image to a corresponding gray level value in the original image, and enables the display content of the superimposed image to achieve the paper image effect without affecting the content in the low gray level region in the original image.
Optionally, fig. 5 shows a schematic flow diagram of an optional signal processing, as can be seen from fig. 5, the electronic device stores a designed texture image with a texture transparency effect in a Flash storage module, and when the user selects an application to display with a paper image effect, the electronic device starts a paper image output function, decompresses the transparent texture image with the paper image and outputs the decompressed texture image to a GPU video memory module, and then outputs the image. Meanwhile, the signal processing and output section acquires an original image (i.e., signal input in fig. 3), and performs image scaling and then color space conversion on the original image. Meanwhile, the electronic device analyzes RGB data of the original image and the superimposed image, calculates gray values of the RGB data of the superimposed image, and then performs image processing, such as processing of image brightness, contrast, GAMMA data, and the like, to adjust the gray values of the superimposed image so that the low gray area of the superimposed image is restored to the gray value of the low gray area corresponding to the original image. Finally, the electronic device outputs the image.
As can be seen from the above, according to the scheme provided by the application, display contents in applications do not need to be modified, and the display contents of all applications can be adjusted to the preset texture effect in a way of layer overlay and image processing, for example, the display contents of all applications are adjusted to the paper texture effect. In addition, the scheme provided by the application can adjust the input signals under any channel, such as HDMI, built-in PC or security desk, VGA and the like, without adjusting the content of the input signal source (namely, original image). Finally, the scheme provided by the application can design various texture superposition effects for the user to select, for example, effects such as white paper and rice paper, but not limited to the texture effects listed in the embodiment.
