Summary:The invention discloses a noise estimation method, an image processing method and device, and a storage medium, and the noise estimation method comprises the steps: obtaining a mapping derivation result according to a mapping curve; obtaining an original estimation result, wherein the original estimation result is a noise estimation result of the original image; and obtaining a noise estimation result of the to-be-estimated image according to the mapping derivation result and the original estimation result. Noise estimation is carried out on the to-be-estimated image obtained after nonlinear mapping, hardware resources can be effectively saved, and the noise estimation result is obtained according to the mapping derivation result related to the mapping curve of nonlinear mapping and the original estimation result. Therefore, the noise estimation result is related to the non-linear mapping, the accuracy of the noise estimation result is higher, the effect of subsequent noise reduction processing can be effecti
