Embodiment Construction
[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.
[0028] At present, the adjustment of image brightness is limited to manual debugging by the user when taking pictures or post-processing after taking pictures. Manual debugging is prone to photo brightness being adjusted to be too bright or too dark, resulting in photo distortion. At the same time, it is difficult to quickly determine the appropriate brightness value through manual adjustment, and the efficiency of brightness adjustment is low. Embodiments of the present invention provide a technical solution cap...

The invention discloses an image processing method, device, terminal and computer-readable storage medium. The method includes: acquiring the ambient brightness value when the target image is acquired by the camera; judging whether the first brightness value of the target area in the target image exceeds a preset brightness interval; if the first brightness value of the target area exceeds the preset brightness interval, then according to Ambient Brightness Value adjusts the brightness value of the target area. In the image processing method provided by the embodiment of the present invention, first, when the target image is acquired by the camera, the ambient brightness value is acquired by the light sensor; then it is judged whether the first brightness value of the target area in the target image exceeds the preset brightness interval; when the target area When the first brightness value exceeds the preset brightness range, the brightness value of the target area is adjusted according to the ambient brightness value, so as to improve the accuracy of photo brightness adjustment and avoid photo brightness distortion.
Description
technical field [0001] Embodiments of the present invention relate to image brightness processing technologies, and in particular, to an image processing method, device, terminal, and computer-readable storage medium. Background technique [0002] With the development of smart phones, taking pictures has become an essential function of mobile phones. However, limited by the thickness and volume of the mobile phone, the aperture and focal length of the camera cannot be adjusted freely. As a result, photos in low-light environments or strong-light environments appear too dark or overexposed. [0003] Aiming at this problem, the prior art provides the user with a slider for adjusting the brightness when taking pictures, and the user can adjust the brightness according to his / her preference. However, users adjust the brightness according to their own preferences, which is prone to distortion problems such as high or low brightness of the photo. Contents of the invention [...
