The invention discloses a histogram processing and adjusting method, an image processing method, a storage medium and electronic equipment. The histogram processing method comprises the steps that K bins in a histogram are sequentially processed, 0 < = j < = K-1, and the processing of the jth bin comprises the steps that when the pixel number of the jth bin is larger than or equal to the limit value of the jth bin, the pixel number of the jth bin is adjusted to be equal to the limit value of the jth bin, and a first updating step is executed; and when the pixel number of the jth bin is smaller than the limit value of the jth bin, the pixel number of the jth bin is increased, the second updating step is executed, the increased pixel number is at least related to a lifting coefficient, and the lifting coefficient is the ratio of the total deletion amount and the total remaining amount updated after the (j-1) th bin is processed. 一种直方图处理、调整和图像处理方法、存储介质和电子设备。直方图的处理方法包括：依次处理直方图中的K个bin，其中，0≤j≤K-1，第j个bin的处理包括：当第j个bi
