Image color gradation simplification method and device, equipment and storage medium

The invention discloses an image color gradation simplification method and device, equipment and a storage medium. The method comprises the following steps: determining at least two target color gradations from a color gradation sequence of original image data, wherein the color gradation sequence comprises all color gradations arranged according to the size; mixing every two adjacent target color gradations into a target false color gradation unit; and filling and covering the target false color gradation unit in the adjacent color gradation group formed by every two corresponding adjacent target color gradations in the original image data, obtaining the simplified color gradation image, and reserving the brightness color gradation hierarchical effect, wherein the color gradation transition of the simplified image is softer. 本发明公开了一种图像色阶简化方法及装置、设备、存储介质，方法包括：从原始图像数据的色阶数列中确定出至少两个目标色阶；其中，色阶数列包括按照大小排列的所有色阶；以每两个相邻的目标色阶混合成目标伪色阶单元；将目标伪色阶单元填充覆盖至原始图像数据中相应的每两个相邻目标色阶所构成的相邻色阶组内，获得简化色阶图像，可以保留亮度色阶层次效果，使简化后的图像色阶过度更柔和。
