Image processing method and device and nonvolatile computer readable storage medium

The invention relates to an image processing method and device and a nonvolatile computer readable storage medium, and relates to the technical field of image processing. The image processing method comprises the following steps: segmenting an image to be processed into a plurality of sub-images; dividing the plurality of sub-images into a plurality of sub-image sets; and performing histogram equalization processing on each sub-image set by using a histogram equalization method corresponding to each of the plurality of sub-image sets to obtain a histogram equalization result of the to-be-processed image. According to the technical scheme, the image processing cost can be reduced, and the image processing effect is improved. 本公开涉及一种图像处理方法、装置和非易失性计算机可读存储介质，涉及图像处理技术领域。该图像处理方法，包括：将待处理图像分割为多个子图像；将多个子图像，划分为多个子图像集合；利用与多个子图像集合中的每一个对应的直方图均衡方法，分别对每一个子图像集合进行直方图均衡处理，以获取待处理图像的直方图均衡结果。本公开的技术方案能够降低图像处理成本、提高图像处理效果。
