1. An apparatus for obtaining a motion adaptive high dynamic range image, the apparatus comprising: a motion calculation unit configured to: receive a first image and a second image that are taken using different exposure times; and calculate a motion degree of the second image by comparing the first image with the second image; a first compensation unit configured to compensate the second image for global motion; a second compensation unit configured to compensate the second image for local motion; an image synthesizing unit configured to: receive images output from the first compensation unit or the second compensation unit; and synthesize the received images; a single image selection unit configured to select at least one of the first image, the second image, and an auto-exposure image; and a control unit configured to, based on the calculated motion degree, allow the first and second images to be provided to the image synthesizing unit via at least one of the first compensation unit and the second compensation unit or to the single image selection unit, wherein: in response to the motion degree being global and lying within a permissible range of compensation, the control unit is further configured to allow the first and second images to be input into the image synthesizing unit via the first compensation unit; in response to the motion degree being local and lying within the permissible range of compensation, the control unit is further configured to allow the first and second image to be input into the image synthesizing unit via the second compensation unit; in response to the motion degree being composite and lying within the permissible range of compensation, the control unit is further configured to allow the first and second images to be input into the image synthesizing unit via the first and second compensation units; and in response to the motion degree lying outside the permissible range of compensation, the control unit is further configured to allow the first and second images to be input into the single image selection unit, and wherein the global motion compensation is performed through an image stabilizer.
