ABSTRACT:
According to the method of synthesizing a image from a plurality of images, each of the luminance I.sub.p1xy -I.sub.pNxy of each of the pixel p.sub.1xy -p.sub.Nxy positioned at the same coordinates (x,y) of N images P.sub.1 -P.sub.N are compared with each of the predetermined threshold luminance T.sub.1 -T.sub.N corresponding to images P.sub.1 -P.sub.N, wherein "N" is a natural number greater than 1. If the luminance I.sub.p1xy -I.sub.pNxy of the pixels p.sub.1xy -p.sub.Nxy are all greater than the corresponding threshold T.sub.1 -T.sub.N of corresponding image, the synthesized pixel p.sub.xy at the coordinate (x,y) of a synthesized image is determined by synthesizing the pixels p.sub.1xy -p.sub.Nxy with predetermined synthesis ratio for each of the images P.sub.1 -P.sub.N. If the condition described above is not satisfied, the synthesized pixel p.sub.xy at the coordinate (x,y) of the synthesized image is determined by synthesizing with arbitrary synthesis ratio only the pixels having luminance less than or equal to the corresponding threshold T.sub.1 -T.sub.N among the pixels p.sub.1xy -p.sub.Nxy. The procedure described above is performed with regard to all pixels in the region wherein images are to be synthesized.
