Claim 8:
9. A device for processing spectrum data, the device comprising:
a light source configured to irradiate light toward an object;
an image sensor configured to obtain spectrum response signals corresponding to channels of spectrum data of light, the spectrum data being obtained from the object by the image sensor; and
a processor configured to:
determine a set of bases corresponding to the obtained spectrum response signals;
perform, based on the determined set of bases, a change of basis on at least one basis included in the determined set of bases; and
generate, by using a pseudo inverse, reconstructed spectrum data from the spectrum response signals on which the change of basis has been performed,

wherein the processor is further configured to determine at least one basis having a singular value less than a threshold value among the bases corresponding to the obtained spectrum response signals, and replace the singular value of the determined at least one basis with a certain singular value.
