A method for processing an image and an electronic device therefor are provided. The electronic device includes an image sensor, a memory, and a processor. The processor is configured to obtain a raw image using the image sensor, identify recognition information about a plurality of sub-regions corresponding to a plurality of objects included in the raw image, based on image recognition using the raw image, generate a first image by performing a first calibration process on the raw image using a first parameter set associated with first recognition information corresponding to a first sub-region among the plurality of sub-regions, generate a second image by performing a second calibration process on the raw image using a second parameter set associated with second recognition information corresponding to a second sub-region among the plurality of sub-regions, and generate a third image by using a region of the first image corresponding to the first sub-region and a region of the second image corresponding to the second sub-region.
