1. A method, performed by an electronic device, the method comprising:
obtaining an image by a camera of the electronic device;
obtaining a first sharpening kernel for enhancing sharpness of the image, wherein the first sharpening kernel is data including a plurality of weights to be applied to pixels in the image, and the data is of a lower resolution than the image;
determining coordinates corresponding to first weights indicating representative values of the first sharpening kernel from among the plurality of weights in the first sharpening kernel, wherein the representative values are values indicating feature points of a shape of the first sharpening kernel;
generating a second sharpening kernel by selecting the first weights corresponding to the determined coordinates; and
obtaining a sharpened image by applying the second sharpening kernel to the image.
