This paper presents an efficient color matching approach to address the photometric inconsistency problem that commonly exists in panoramic images. Color correction, as the first step, is to adjust the color and luminance of source images so that the differences between adjacent images can be minimized. Color blending is used after the color correction to further smooth the color transition between adjacent images. With the first image being selected as a basis image, the proposed approach can start the color matching and stitching process once the second image is captured. The proposed approach is simple and is very suitable for panoramic imaging on mobile devices. Experimental results demonstrate that the color transitions between neighboring images are smooth without visible seams and the color tone of the final image is kept as close as the basis image
