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 accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
These and other aspects of embodiments of the invention will be apparent with reference to the following description and attached drawings. In the description and drawings, particular embodiments of the invention have been disclosed in detail as being indicative of some of the ways in which the principles of the embodiments of the invention may be practiced, but it is understood that the scope of the embodiments of the invention is not limited correspondingly. On the contrary, the embodiments of the invention include all changes, modifications and equivalents coming within the spirit and terms of the claims appended hereto.
Referring to fig. 1, the image adjustment method according to the first embodiment of the present invention includes steps S11-S12.
Step S11, acquiring a current image in YUV format captured by the camera in real time, and acquiring a color mode selected by the user as a current color mode, where the color mode includes a corresponding relationship between at least a color to be adjusted and a target color, and the value of the Y component of the color to be adjusted is the same as the value of the target color.
The image adjusting method in the embodiment is applied to a terminal, and the terminal has a photographing function and is provided with a camera. The terminal is, for example, a mobile phone, a tablet computer, a wearable device, and the like, and is used for performing real-time image processing on an image captured by a camera.
In the prior art, colors are represented by various modes such as an RGB mode, an HSV mode, a YUV mode, and the like, and the color mode of an image shot by a camera is determined by the color coding mode of the camera. Different color modes correspond to different color components, such as RGB components or YUV components. In this embodiment, the format of an image taken by a camera is a YUV format, the YUV mode is divided into three components, "Y" represents brightness (Luma or Luma), that is, a gray value; "U" and "V" represent Chrominance (or Chroma) that is used to describe the color and saturation of an image for specifying the color of a pixel.
When a user takes a picture, the color in the picture can be changed according to the preference of the user, for example, the red color in the picture can be changed into pink, and the green color can be changed into yellow and blue, and the like. In specific implementation, a plurality of color modes can be prestored in the terminal, and each color mode comprises at least one corresponding relation between the color to be adjusted and the target color. The color to be adjusted is different from the target color only in the UV component, the Y component is the same, when the color is to be modified, the brightness value is unchanged, the finally presented image effect is changed from the color of the original image, and the image adjusting effect is natural and real. In each color mode, each color to be adjusted may correspond to a different target color, or a plurality of colors to be adjusted may correspond to the same target color, which is set according to actual conditions.
The plurality of color modes pre-stored in the terminal can present different effects, such as autumn mode, summer mode, color mode, etc. The autumn style is, for example, adjusting green in the image to yellow, and adjusting blue to gray; summer mode is to adjust yellow to green, gray to blue, etc., and may exhibit an out-of-season effect. The color mode, for example, is to adjust the gray, black and white colors to be bright colors, such as red, blue and green, respectively, so as to form a colorful effect. Images presented in the various color modes can be previewed on a display interface of the camera, and a user can select a favorite color mode according to the previewed effect.
It can be understood that the color mode in the terminal can be preset by the camera system, and can also be set and added by the user according to the user preference as a custom color mode.
It is understood that the step of obtaining the current color mode selected by the user may further include the following steps:
and acquiring the color mode with the maximum use frequency, and sending out a reminding message to prompt a user whether to take the color mode with the maximum use frequency as the current color mode.
And in the terminal, recording and storing the use frequency of each color mode in real time, and determining the color mode with the maximum use frequency. And when the confirmation information based on the prompt information is received, acquiring the color mode with the maximum use frequency as the current color mode. And then, a prompt can be sent according to the use habit of the user to suggest a proper color mode, so that the user experience is enhanced.
Step S12, determining a current color to be adjusted in the current image according to the current color mode, and adjusting the current color to be adjusted to a target color in the current color mode, so that the current image is adjusted to an image matching the current color mode.
And when a color mode selected by the user is acquired, taking the color mode as the current color mode, and adjusting the current image. In the above step, according to the color to be adjusted in the current color mode, the color same as the color to be adjusted is inquired in the current image as the current color to be adjusted. And replacing the current color to be adjusted with the target color in the current color mode.
In specific implementation, the color of each pixel point in the current image is obtained, and the color component of the pixel point with the same color to be adjusted in the current mode is correspondingly changed, so that the change of the image color can be realized, and the image matched with the current color mode can be obtained.
In the embodiment, the color in the image shot by the camera can be changed according to the color mode selected by the user, so that the changed image is only changed in color and is unchanged in brightness, the image after adjustment is natural and real, and the requirements of the user are met.
FIG. 2 shows an image adjustment method according to a second embodiment of the present invention, which includes steps S21-S26.
In step S21, the current image captured by the camera is acquired in real time.
Step S22, obtaining RGB values of at least one color to be adjusted selected by the user in the current image, and obtaining RGB increments for the color to be adjusted selected by the user.
In practical applications, the color mode pre-stored in the terminal may not be suitable for the current photo, or the user wants to modify the color of the photo according to his/her preference. In view of this, in this embodiment, the user may select one or more colors in the current image to modify.
Since the format of the current image is YUV format, the adjustment of color is performed by adjusting the U component and the V component of each pixel. For the user, it is not intuitive to adjust the color by adjusting the U component and the V component, and therefore, in this embodiment, the YUV format of the color to be adjusted selected by the user is converted into the RGB format.
The image in YUV format is converted into the image in RBG format, and the conversion can be performed according to the YUV and RGB conversion formula in the prior art. For example, by the following conversion formula:
Y＝0.257R+0.504G+0.098B+16；
V＝0.439R－0.368G－0.071B+128；
U＝－0.148R－0.291G+0.439B+128；
where RGB ranges from [0, 255], Y ranges from [16, 235], and UV ranges from [16, 239 ].
In specific implementation, a user opens a current image on a display interface of a camera application, selects a color of a position on the image, and a terminal acquires an RGB value of the color of the position through a color extraction tool, displays the RGB value and simultaneously displays a color value-added setting option. The color increment setting option is used for the user to modify the RGB values of the selected color, and the user can adjust the value of each color component up or down, that is, the color increment can be a positive value or a negative value. In the prior art, there are many tools for color extraction or color capture, and in this embodiment, colors can be extracted from the current image by any color extraction method.
And step S23, summing the RGB value and the RGB increment to obtain an RGB value of a new color, and converting the RGB value of the new color into a YUV format.
And summing the RGB value of the color to be adjusted selected by the user and the RGB added value of the color to be adjusted to obtain the RGB value of the new color. For example, the RGB value of red when the user selects in the current image is (255, 0, 0), the color increment set by the user is that the R and G increments are both 0, and the B increment is 255. The RGB value of the new color obtained after the summation calculation is (255, 0, 255), i.e. purple.
The adjustment of the color through the RGB value is more accurate and wider, and the current color to be adjusted can be adjusted to be any color.
As an example, in a specific implementation, the color to be adjusted selected by the user may also be displayed on a display interface in a color block, and a target color list is displayed on the display interface, where the target color list includes a plurality of preset target colors, and the user can more intuitively see the presentation effect of the color to be adjusted and the adjusted color selected by the user. For example, the color to be adjusted selected by the user is red, and one target color, such as purple, is selected from a preset target color list. The terminal acquires RGB values (255, 0, 255) of the target color selected by the user.
The color change in the RGB mode is very convenient, but the brightness of the adjusted image needs to be kept unchanged in the YUV mode. The color conversion from the RGB format to the YUV format can be performed by adopting a conversion formula of RGB and YUV in the prior art. For example, by the following conversion formula:
B＝1.164(Y－16)+2.018(U－128)；
G＝1.164(Y－16)－0.813(V－128)－0.391(U－128)；
R＝1.164(Y－16)+1.596(V－128)；
where RGB ranges from [0, 255], Y ranges from [16, 235], and UV ranges from [16, 239 ].
It is understood that the above mentioned conversion formula between RGB and YUV is only a formula used in a domain and threshold, and any conversion formula in the prior art can be used in practical application, and is not limited herein.
Step S24, extracting the value of the Y component in the current color to be adjusted and the values of the U component and the V component of the new color, taking the extracted values of the Y component, the U component and the V component as the component values of the target color and establishing a corresponding relationship with the color to be adjusted selected by the user to obtain the current color mode.
The YUV components of the color to be adjusted selected by the user have values of (y1, u1, v1), and the YUV components of the new color have values of (y2, u2, v 2). The UV component is used to distinguish colors, Y represents brightness, and the brightness is maintained unchanged after the color to be adjusted is color-adjusted, the Y component of the new color needs to be consistent with the Y component of the color to be adjusted selected by the user. Therefore, the (y1, u2, v2) value is used as the component value of the target color to establish the corresponding relation with the color to be adjusted selected by the user, and the current color mode can be obtained.
Further, the obtained current color mode can be stored in the terminal so as to be directly called when used next time.
Step S25, determining a color in the current image that is the same as the YUV component value of the color to be adjusted in the current color mode, to obtain the current color to be adjusted.
Step S26, modifying the value of Y, U, V component of each pixel point corresponding to the current color to be adjusted to be the same as the value of YUV component of the target color in the current color mode.
In the step S21, the user selects a color to be adjusted from the current image, determines a corresponding target color according to the steps S22 to S24, and associates the color to be adjusted selected by the user with the determined target color to serve as the current color mode. Specifically, when image adjustment is performed, each pixel point in the current image is traversed, a color which is the same as the YUV component value (y1, u1, v1) of the color to be adjusted selected by the user is determined, and the color to be adjusted is taken as the current color to be adjusted. And re-coloring the pixel point corresponding to the current color to be adjusted in the current image to make the pixel point same as the YUV component values (y1, u2 and v2) of the target color in the current color mode, thereby realizing the adjustment of the current image.
Compared with the first embodiment, in the present embodiment, the user can obtain the current color mode based on the current captured image, and adjust one or more colors of the captured image in a targeted manner.
Further, the user may add a color mode to the terminal, please refer to fig. 3, which is an image adjusting method according to a third embodiment of the present invention, and based on the first embodiment or the second embodiment, the method further includes steps S31 to S32:
step S31, acquiring at least one color to be adjusted selected by a user in a color setting mode of the camera, and acquiring a target color corresponding to the color to be adjusted selected by the user;
and step S32, storing the color to be adjusted selected by the user and the corresponding target color as a color mode.
In specific implementation, a color list to be debugged is presented in a color setting mode of the camera, a plurality of first color graphs are displayed in the color list to be debugged, a user can select at least one first color in the color list as a color to be adjusted, and a corresponding target color is added to the selected color.
In particular, after the user selects the first color icon in the color list, a target color list is popped up, and the target color list is in the form of a plurality of second color icons. At this time, the color list to be debugged may be in a hidden state or may be displayed in a reduced manner on the display interface. The user makes a selection of the second color in the list of target colors. And respectively taking the current first color selected by the user and the current second color selected by the user as the color to be adjusted and the target color, and establishing a corresponding relation. After a corresponding relation is established, the display interface hides the target color list, a user can continuously select a first color from the color list to be adjusted as a color to be adjusted, after one first color is selected, the target color list is displayed, and the user can continuously select a second color as a target color. And analogizing in sequence, establishing corresponding relations between all first colors selected by the user in the color list to be debugged and second colors selected in the target color list, and storing the first colors as a color mode. The user can use the custom color mode when taking a picture.
In this embodiment, the color to be debugged and the target color can be selected from the color list to be debugged and the target color list, the corresponding target colors can be set for a plurality of colors to be debugged, and the colors can be stored as a color mode, which is very intuitive and convenient. The user can set the color mode according to own hobby, and is convenient and practical.
