An image processing apparatus includes circuitry configured to: acquire a plurality of pieces of image data; determine, for each of the plurality of pieces of image data, a first representative color indicating a feature of a color representative of the image data, based on pixel values of the image data; calculate, based on the determined first representative color of the plurality of pieces of image data, a second representative color indicating a feature of a color representative of the plurality of pieces of image data; calculate, based on the first representative color and the second representative color of image data to be corrected, a correction parameter for color correction of the image data to be corrected among the plurality of pieces of image data; and perform the color correction on the image data to be corrected using the calculated correction parameter.
