Problems solved by technology

[0003] However, in the first noise reduction process, other areas in the picture except the bright area and dark area have been successfully denoised. After denoising the picture again, the other areas mentioned above will lose clarity due to multiple noise reductions. becomes lower, thereby reducing the overall sharpness of the picture

Embodiment 1

[0068] An embodiment of the present invention provides an image processing method, such as Figure 5 As shown, the method may include:

[0069] S101. When receiving an image processing instruction for a picture to be processed, convert the picture to be processed from the RGB domain to the YUV domain, and divide the picture to be processed into at least one color block in the domain to be processed.

[0070] A picture processing method provided by an embodiment of the present invention is applicable to a scenario where a terminal performs noise reduction on a picture.

[0071] In the embodiment of the present invention, when the user uses the terminal to take pictures, or when the user optimizes the pictures on the terminal, the user clicks the shooting button or the optimization button on the terminal interface. At this time, the terminal receives the picture processing instruction, and the terminal Obtain the image to be processed according to the image processing instructi...

Embodiment 2

[0100] An embodiment of the present invention provides an image processing method, such as Figure 8 As shown, the method may include:

[0101] S201. When receiving an image processing instruction for a picture to be processed, convert the picture to be processed from the RGB domain to the YUV domain, and divide the picture to be processed into at least one color block in the domain to be processed.

[0102] A picture processing method provided by an embodiment of the present invention is applicable to a scenario where a terminal performs noise reduction on a picture.

[0103] In the embodiment of the present invention, when the user uses the terminal to take pictures, or when the user optimizes the pictures on the terminal, the user clicks the shooting button or the optimization button on the terminal interface. At this time, the terminal receives the picture processing instruction, and the terminal Obtain the image to be processed according to the image processing instructi...

Embodiment 3

[0145] Figure 9 Schematic diagram 1 of the composition and structure of the terminal proposed for the embodiment of the present invention. In practical applications, based on the same inventive concept of Embodiment 1 and Embodiment 2, as follows Figure 9 As shown, the terminal 1 in the embodiment of the present invention includes: a processor 10 , a memory 11 and a communication bus 12 .

Abstract

The embodiment of the invention discloses a picture processing method, a terminal and a computer-readable storage medium, and can improve the definition of a picture. The method includes the steps ofwhen receiving a picture processing instruction on a to-be-processed picture, switching the to-be-processed picture from an RGB domain to a YUV domain, and dividing the to-be-processed picture into atleast one color lump in a to-be-processed domain; in the YUV domain, obtaining at least one brightness value corresponding to at least one color lump; when judging that a first color lump belongs toa to-be-processed color lump, according to the first brightness value corresponding to the first color lump, calculating a first weight value corresponding to the first color lump, wherein the first color lump is a color lump in at least one color lump, and the first brightness value is a brightness value corresponding to the first color lump in at least one brightness value; using the first weight value to conduct de-noise processing on the first color lump, and thus completing the processing process on the to-be-processed picture.

Description

technical field [0001] The present invention relates to the field of electronic applications, in particular to an image processing method, a terminal and a computer-readable storage medium. Background technique [0002] In recent years, with the rapid development of mobile terminals such as mobile phones, mobile terminals can not only realize basic communication functions such as calling, but also realize additional functions such as photo shooting, video viewing and instant messaging. When using mobile terminals to take pictures, In order to enhance the display effect of the captured pictures, the image noise reduction algorithm is used to reduce the noise in the pictures. However, if Figure 1a As shown, the RGB value of the white area should be 255, but after noise reduction, the R value becomes 245, as shown in Figure 1b As shown in , the black area shows color overlapping after zooming in. Therefore, in the image after noise reduction, there will be color difference ...
