Based on the above intelligent terminal hardware structure and communication network system, various embodiments of the present application are provided.
For the convenience of understanding, a specific application scenario of the embodiment of the present application is first introduced. With the development of terminal technology, people pay more and more attention to the shooting effect of terminal equipment when selecting the terminal equipment, and the requirement on the image processing technology of the terminal equipment is higher and higher.
Taking the white balance processing technique of an image as an example, if the color temperature of a light source in a shooting scene is at a low/medium color temperature, more red gain compensation is performed, which may cause the shot image to be reddish. If the color temperature of the light source in the shooting scene is at a high color temperature, the blue gain compensation is more, which causes the shot image to be blue. That is, when the camera takes an image, the color temperature of the light source in the scene may be affected, which may cause a certain programmed deviation of the colors of the taken image. In order to make the color of the image shot by the camera consistent with the color of the scene received by human eyes, the white balance processing technology can perform white balance compensation on the image, namely, the deviation of the color of the image is corrected.
However, when the white balance processing technology performs white balance compensation, the white balance gain value is adjusted according to the proportion weight of each light source with different color temperature in the scene, and the processing cannot be completely performed according to the color distribution condition of the actual complex scene in the adjustment process, and the white balance processing process is fully automatic and cannot be adjusted correspondingly according to the preference of the user.
Based on this, an embodiment of the present application provides an image processing method, an intelligent terminal, and a storage medium, where a first image is obtained after a first image processing is performed on a captured image, a second image processing parameter is obtained if a processing effect of the first image does not achieve an expected effect, and then a second image processing is performed on the first image or a second region of the first image according to the second image processing parameter, so that a finally obtained target image achieves the expected effect, a user demand is met, and a user experience is improved.

It should be explained that the purpose of the white balance gain value is mainly to "restore a white object to white regardless of any light source", and compensate for the color cast phenomenon occurring when a picture is taken under a specific light source by enhancing the corresponding complementary color. Therefore, the white balance gain value can be understood as a complementary color parameter required to restore a white object in the photographed original image to white. Alternatively, the white balance compensation process may use an existing white balance compensation algorithm, such as a gray world algorithm, a perfect reflection algorithm, and the like, which is not described herein.

The terminal performs automatic white balance processing on the shot original image once to obtain a first image. The terminal detects image parameters of the first image, optionally white balance gain values of the first image. If the white balance gain value in the red channel of the first image is detected to exceed the preset threshold (which indicates that the first image is still reddish), the terminal generates a secondary processing instruction, and the secondary processing instruction is used for reducing the white balance gain value of the red channel of the first image. The terminal responds to the secondary processing instruction, and automatically selects an area with a smaller R value (which can be an area with the R value smaller than a preset threshold value) in the first image as the first area.
