1. An electronic apparatus comprising:
a camera;
a memory in which a plurality of images captured through the camera and a parameter value of the camera are stored; and
a processor electrically connected to the camera and the memory and configured to:
identify, among a plurality of preset scene types, a scene type corresponding to each captured image of the plurality of captured images;
extract a feature point of each captured image of the plurality of captured images by applying one of different feature point extraction methods, which are respectively preset in association with the plurality of preset scene types, according to the identified scene type of each captured image, wherein feature points extracted by the different feature point extraction methods have different feature types;
obtain a calibration parameter value based on distortion information corresponding to a feature type, among the different feature types, of each extracted feature point;
obtain an integrated calibration parameter value based on the obtained calibration parameter value corresponding to the feature type; and
update the parameter value stored in the memory based on the integrated calibration parameter value.
