1. An electronic device comprising:
an image sensor including a plurality of pixel groups respectively corresponding to a plurality of exposure values; and
a controller configured to:
select a reference scale image having a minimum exposure value and a target scale image having an exposure value different from the minimum exposure value, among a plurality of scale images that are obtained based on the plurality of pixel groups, and
output an output image obtained using a motion map indicating a positional change of an object that is commonly included in the reference scale image and the target scale image,
wherein the controller comprises a motion value calculator configured to obtain the motion map that includes a motion value that is calculated based on a distance between a first area included in the reference scale image and a second area included in the target scale image, each of the first area and the second area indicates the object, and
wherein the motion value calculator calculates a value that is proportional to the distance as the motion value when the distance exceeds a minimum reference value and is equal to or less than a maximum reference value.
