An image processing method and an apparatus are provided. The image processing method includes acquiring first image data including a plurality of target pixels, acquiring synthesis information by which a relationship, between each of the plurality of target pixels included in the first image data and at least one background pixel included in different image data to be synthesized with the first image data, is determined, and synthesizing a target pixel of the first image data with the at least one background pixel of second image data, based on the synthesis information according to determination of the second image data. The second image data includes the different image data to be synthesized with the first image data.
