| Summary: | 碩士 === 國立臺灣師範大學 === 圖文傳播學系 === 94 === Image synthesis technology plays an important role in digital content creation. In order to present the image with much higher quality, the developed technology is based on color temperature adjustment of the foreground and background images. This research includes two parts. First of all, the color temperature of the illuminant in the shooting environment is estimated. Several methods of color temperature estimation are derived, including the highlight estimation, gamut estimation, hue-segment color temperature loci estimation, and hue-non-segment color temperature loci estimation. Secondly, by the concept of changing illuminant color temperature of images, adjusting the color temperature of the images to be the same and synthesize them. The proposed method can avoid the problem of unnatural image synthesis. Our method is proved by the research to create natural image synthesis results.
