Abstract
Provided is a method for processing an image. The method comprises: determining a target processing mode corresponding to a first image to be processed; determining, based on the target processing mode, image processing parameters corresponding to the first image; determining, based on the image processing parameters and an initial pixel value of a pixel in the first image, a target pixel value of the pixel point from pixel values corresponding to a plurality of alternative colors; and acquiring a second image by converting the initial pixel value of the pixel in the first image into the target pixel value.

A method for processing an image, comprising:
- determining a target processing mode corresponding to a first image to be processed;
- determining, based on the target processing mode, image processing parameters corresponding to the first image, wherein the image processing parameters further comprise a contrast enhancement ratio;
- performing, based on the contrast enhancement ratio, contrast enhancement processing on the first image;
- determining, based on the image processing parameters and an initial pixel value of a pixel in the first image, a target pixel value of the pixel from pixel values corresponding to a plurality of alternative colors;
- and
- acquiring a second image by converting the initial pixel value of the pixel in the first image into the target pixel value;
- wherein said performing, based on the contrast enhancement ratio, contrast enhancement processing on the first image comprises:
- transforming the first image from an RGB color space to an HSV color space;
- acquiring first brightness by determining a mean value of V components of pixels in the first image;
- performing, based on a gamma transformation parameter corresponding to the contrast enhancement ratio, gamma transformation on the V component of each of the pixels;
- acquiring second brightness by determining a mean value of the V components of the pixels after gamma transformation;
- acquiring the first image with an enhanced contrast in the HSV color space by keeping H components and S components of the pixels unchanged and adding a difference between the first brightness and the second brightness on the V components of the pixels after gamma transformation;
- and
- acquiring the first image with an enhanced contrast by transforming the first image with the enhanced contrast in the HSV color space to the RGB space.
