Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
An image processing method, an apparatus, a mobile terminal, and a computer-readable storage medium according to embodiments of the present invention are described below with reference to the accompanying drawings.
Fig. 1 is a flowchart of an image processing method according to an embodiment of the present invention. It should be noted that the image processing method according to the embodiment of the present invention can be applied to an image processing apparatus, and the apparatus can be configured on a mobile terminal.
As shown in fig. 1, the image processing method includes:
and S110, acquiring the to-be-processed image selected by the user.
In the embodiment of the invention, the user can upload the selected to-be-processed image through the mobile terminal, so that the mobile terminal acquires the to-be-processed image selected by the user. For example, any image can be extracted from a locally pre-stored image set as an image to be processed.
In the embodiment of the present invention, the mobile terminal includes, but is not limited to, a mobile phone, a tablet computer, and other hardware devices having various operating systems.
It should be noted that the operation of acquiring the to-be-processed image selected by the user may be to pre-select an image to be processed before processing the image, or may be to prompt the user to provide or upload an image to be processed after detecting that the user triggers the image processing operation.
And S120, generating a gray-scale image according to the image to be processed.
That is to say, after the mobile terminal acquires the to-be-processed image selected by the user, the gray scale adjustment can be performed on the to-be-processed image, so that a gray scale image is generated.
In the embodiment of the present invention, the grayscale image can be generated in the following two ways, which are specifically implemented as follows:
as a possible implementation manner, the saturation of each primary color in the image to be processed may be reduced to a preset value, so as to obtain a corresponding grayscale image. Wherein saturation may be used to describe the degree of similarity between a color and a standard color. As an example, the preset value may be 0.
For example, take "image to be processed 1" as an example, wherein the principle of displaying the image of "image to be processed 1" is: each pixel point is composed of three sub-pixels of R (red), G (green) and B (blue), and because human eyes have different sensitivities to R, G, B three primary colors, human eyes can recognize the colors of the three primary colors, the saturation of the three primary colors of the image to be processed 1 is reduced to a parameter with a preset value of zero, and a gray-scale image corresponding to the image to be processed 1 can be obtained.
As another possible implementation manner, configuration information of a user for a gray scale degree may be acquired, and then a corresponding saturation target value is determined according to the configuration information, and the saturation of each primary color in the image to be processed is reduced to the corresponding saturation target value, so as to obtain a gray scale image.
The configuration information can be understood as gradation of gray scale level.
For example, before generating a grayscale image according to an image to be processed, a first configuration interface may be provided to a user, where the first configuration interface includes a configuration control for a grayscale level, and the first configuration interface is configured to receive configuration information when the user configures the grayscale level through the configuration control.
That is to say, when a user adjusts the gray scale degree of an image to be processed through a configuration control provided by the mobile terminal, the mobile terminal may obtain the level information for the gray scale degree, then determine the corresponding saturation target value according to the level information for the gray scale degree, and reduce the saturation of each primary color in the image to be processed to the corresponding saturation target value, thereby obtaining a gray scale image.
For example, a user performs gray scale degree adjustment on the image to be processed 1 through a configuration control provided by the mobile terminal, for example, the gray scale degree adjustment may be divided into three levels, when it is determined that the user adjusts the gray scale degree of the image to be processed 1 to a first-level gray scale through the configuration control, the corresponding saturation target value may be determined to be-90 degrees according to the first-level gray scale, and then the saturation of each primary color in the image to be processed is reduced to-90 degrees, so as to obtain a gray scale image.
It should be noted that the configuration control of the gray scale degree can be understood as a progress bar for adjusting the gray scale degree, wherein the progress bar for adjusting the gray scale degree has a scale; the configuration information may be understood as gradation of gray scale level.
That is, after acquiring the to-be-processed image selected by the user, the mobile terminal may provide the user with a progress bar for gray scale degree adjustment, where the progress bar for gray scale degree adjustment has gradation scales therein.
In the embodiment of the invention, a user can select the grade scale through the progress bar or slide the length of the progress bar to realize the selection of the gray scale degree, so that the first configuration interface receives the information that the user selects the grade of the gray scale degree through the progress bar.
In an embodiment of the present invention, at any time after the mobile terminal acquires the to-be-processed image selected by the user, the mobile terminal may provide a configuration interface for the grayscale level to the user, and then may perform grayscale adjustment on the to-be-processed image to generate the grayscale image.

In the embodiment of the present invention, the mobile terminal may also randomly generate a single color map in advance, wherein the single color map is a pure color image.
Optionally, the color system tendency information of the user may be acquired, then the hue of the single color chart is adjusted according to the color system tendency information of the user to obtain a target single color chart, and then the gray-scale image and the target single color chart are mixed to obtain the effect chart. Wherein the blending process may refer to a blending mode in the picture processing.

Wherein the historical data of the user may include historical color information used by the user in image processing.
For example, the mobile terminal may provide an image processing application program for the user, and when the user uses the application program, the mobile terminal may obtain historical color information that is frequently used by the user during image processing before, and determine color system tendency information of the user according to the historical data, so that the mobile terminal obtains the color system tendency information of the user.

For another example, the mobile terminal may provide an image processing application program for the user, and when the user uses the application program, the mobile terminal may obtain the skin color system of the application program, determine the color system tendency information of the user according to the skin color of the application program, and further obtain the color system tendency information of the user.
