The embodiment of the invention provides a pixel value correction method and device and electronic equipment. The pixel value correction method comprises the following steps: determining a current pixel unit in a target image area as a central pixel unit; determining the trend consistency of the gradient variation of the central pixel unit and the gradient variation of the neighborhood pixel units; determining the direction consistency of the pixel value fitting plane of the central pixel unit and the pixel value fitting plane of the neighborhood pixel unit; when the trend consistency indicates that the gradient changes are consistent and the direction consistency indicates that the fitting plane directions are consistent, marking the current pixel unit as an out-of-focus area belonging to the target image area, and updating the current pixel unit based on the next pixel unit of the target image area; and carrying out pixel value correction on the out-of-focus area. According to the scheme of the embodiment o
