1. A method of processing an image by an electronic device, the method comprising:
obtaining a plurality of circular images via at least one fisheye lens;
obtaining fisheye information including lens shading compensation information, wherein the lens shading compensation information includes coefficients of a polynomial function for each of RGB colors of the plurality of circular images and a number of the coefficients; and
transmitting the obtained plurality of circular images and the lens shading compensation information toward another electronic device,
wherein the polynomial function represents relation between lens shading compensation values for the plurality of circular images and a distance from a center of an image of the plurality of circular images,
wherein the polynomial function is w=Σi=1Npi-1·ri-1, where w is a lens shading compensation value for one of the RGB colors, N is the number of the coefficients, pi-1 is a coefficient and r is the distance from the center of the image, and
wherein compensating the plurality of circular images is performed in the another electronic device by using the lens shading compensation values.
