Image processing method and device, image sensor and electronic equipment

The invention discloses an image processing method and device, an image sensor and electronic equipment. The image processing method comprises the following steps: acquiring a Bayer picture; determining green pixels in the Bayer picture, obtaining an n * n pixel matrix with the green pixels as center point pixels, and n being an odd number equal to or larger than 5; obtaining a first average value of green pixels in the n * n pixel matrix in the same channel as the central point pixel, and a second average value of green pixels in the n * n pixel matrix in the different channel from the central point pixel; and compensating the central point pixel according to the first average value and the second average value. According to the image processing method provided by the embodiment of the invention, the green pixel at the central point can be compensated according to the average value of the green pixels of the two channels, so that the difference of the green pixels on the Bayer picture is effectively balanced
