Claim 16:
17. A non-transitory computer-readable recording medium having recorded thereon a program for executing a method of processing spectrum data, the method including:
obtaining spectrum response signals corresponding to channels of spectrum data of light, the spectrum data being obtained from an object by an image sensor;
determining a set of bases corresponding to the obtained spectrum response signals;
performing, based on the determined set of bases, a change of basis on at least one basis included in the determined set of bases; and
generating, by using a pseudo inverse, reconstructed spectrum data from the spectrum response signals on which the change of basis has been performed,
wherein the performing the change of basis comprises:
determining at least one basis having a singular value, which is less than a threshold value, among the bases corresponding to the obtained spectrum response signals; and
replacing the singular value of the determined at least one basis with a certain singular value.
