Embodiment 1
[0051] see figure 1 , this embodiment provides a method for optimizing and editing an image, and the process of the method is specifically as follows:
[0052] 101: Perform curve adjustment on the image to be optimized to obtain a curve-corrected image;
[0053] 102: Perform HSV conversion on each point corresponding to the obtained curve-corrected image to obtain converted values of color H, purity S, and lightness V;
[0054] 103: After weighting the obtained S value, RGB conversion is performed on H, V and the weighted S value to obtain a saturation-corrected image.
[0055] Among them, HSV represents the color model, H represents the color, S represents the purity, and V represents the lightness.
[0056] Furthermore, after performing curve adjustment and saturation correction on the image to be optimized, the method provided in this embodiment also combines contrast correction, so as to further improve the display quality of the image. This embodiment does not specif...
Embodiment 2
[0072] This embodiment provides an image optimization editing method, the method combines curve adjustment, saturation correction and contrast correction, while improving the color of the image to be optimized, it also improves the exposure quality of the image, making the color of the image more vivid, and Does not disrupt the tone of the image. Among them, there are many ways to combine curve adjustment, saturation correction, and contrast correction. Using the method as an example, the image optimization editing method provided in this embodiment will be described in detail. see figure 2 , the method flow is as follows:
[0073] 201: Perform contrast correction on the image to be optimized to obtain a contrast-corrected image;
[0074] For this step, taking the correction of a 24-bit bitmap as an example, the 24-bit image is a dot matrix with RGB channels. Each point on the image has three values of R, G, and B, which respectively represent the values of the red co...
Embodiment 3
[0189] see image 3 , the present embodiment provides a device for image optimization editing, the device includes:
[0190] A curve adjustment module 301, configured to perform curve adjustment on the image to be optimized to obtain a curve-corrected image;
[0191] The first conversion module 302 is configured to perform HSV conversion on each point corresponding to the curve correction image to obtain converted values of color H, purity S and lightness V;
[0192] The second conversion module 303 is configured to perform RGB conversion on H, V and the weighted S value after weighting the obtained S value to obtain a saturation-corrected image.
[0193] see Figure 4 , the device also includes:
[0194] The first contrast correction module 304 is configured to perform contrast correction on the image to be optimized to obtain a contrast correction image before the curve adjustment module performs curve adjustment on the image to be optimized;
[0195]Correspondingly, t...
