1. An electronic device comprising:
a display panel including at least one light source;
an image sensor disposed to receive incident light incident thereon by reflection of light emitted through the at least one light source by an object external to the electronic device;
a first guide structure disposed between the display panel and the image sensor and configured to change a direction of the incident light incident through a fingerprint recognition region of the display panel;
a second guide structure disposed between the first guide structure and the image sensor and configured to change the direction of the incident light incident through the first guide structure; and
a processor operationally connected with the display panel and the image sensor,
wherein the processor is configured to:
obtain image information through the image sensor, based on at least a portion of the incident light incident through the first guide structure and the second guide structure,
wherein the fingerprint recognition region includes a plurality of sub-fingerprint recognition regions,
wherein the first guide structure includes a plurality of lenses arranged spaced apart from each other,
wherein a center of at least one lens among the plurality of lenses of the first guide structure is out of alignment with a center of at least one lens of the second guide structure in a direction from the display panel to the image sensor, and
wherein a center of at least one other lens among the plurality of lenses of the first guide structure is aligned with a center of at least one other lens of the second guide structure in the direction from the display panel to the image sensor.
