When performing image synthesis, in which a plurality of images having different color tones are combined, or when converting the contrast of an image, the prior art is such that a user must convert pixel levels manually. Consequently, it is required that the user have thorough knowledge of the constitution of the image data to undergo the level conversion and of image processing techniques in general. This means that the conversion cannot be performed by anyone in simple fashion. In accordance with the present invention, a conversion table is created automatically based upon the color distribution of first image data in such a manner that the color tone of second image data is made to approach that of the first image data, and the second image data resulting from a pixel level conversion by this conversion table is combined with the first image data, whereby there is obtained a natural composite image. In another aspect, an appropriate contrast conversion can be performed with ease by performing a pixel level conversion in accordance with a conversion table created based upon a pixel level distribution of image data.
