摘要:
This application provides an image processing method, including: adaptively determining at least one interpolation point based on feature information or dynamic metadata of a to-be-processed image, and determining the at least one interpolation point and a modified spline curve that passess through the at least one interpolation point, where the modified spline curve includes at least one of a linear spline curve or a cubic spline curve; and performing tone mapping on the to-be-processed image based on a modified tone mapping curve, where the modified tone mapping curve includes at least a part of an initial tone mapping curve and the modified spline curve. According to the method provided in this application, the tone mapping curve can be adaptively modified based on a scene requirement, so that images in various scenes can have a good display effect.
