An image processing apparatus includes a correcting unit and a pasting unit. The correcting unit corrects a dynamic range of a second image in accordance with pixel information of a region. The second image is pasted on a first image serving as a destination for pasting. The region is in the first image and is to be in contact with the second image. The pasting unit pastes the second image on the first image after the correction of the dynamic range. The second image has pixel information. The pixel information is corrected in such a manner that a boundary with the first image is inconspicuously viewed.
