1. An electronic device comprising:
a display to output an image;
a parallax optical element configured to provide light corresponding to the image to a plurality of viewpoints;
an input interface configured to receive an input to calibrate the parallax optical element from a user who observes a pattern image from a reference viewpoint among the plurality of viewpoints; and
a processor configured to:
output the pattern image generated by rendering a calibration pattern toward the reference viewpoint;
adjust at least one of a pitch parameter, a slanted angle parameter, and a position offset parameter of the parallax optical element based on the input; and
output the pattern image adjusted by re-rendering the calibration pattern based on an adjusted parameter,
wherein the processor is further configured to:
rotate a first calibration pattern corresponding to a first pattern image corresponding to the pitch parameter in a counterclockwise direction, based on a counterclockwise rotation control being detected by the input interface while the first pattern image is being provided; and
rotate the first calibration pattern corresponding to the first pattern image in a clockwise direction, based on a clockwise rotation control being detected by the input interface while the first pattern image is being provided.
