Abstract
A color balancing apparatus for multiple image synthesis and a method therefore, in which an automatic white balance unit, with respect to each of a plurality of input images that are obtained by sequentially capturing adjacent scenes, is configured to compare a neutral color representing the input image with chromaticity of standard sources that are predefined, determine a standard source which is closest to the neutral color among the standard sources as a standard illuminant, and perform a white balance on the input image based on the standard illuminant, so that a natural wide-area synthesis image is generated by use of a light source estimation scheme considering multiple light sources, without complex computation of the conventional wide-area image synthesis, are provided.
