Claim 12:
13. An electronic device comprising:
a display panel including a plurality of light sources, the display panel configured to drive first light sources among the plurality of light sources to display an object recognition window on a partial region of the display panel;
an object recognition sensor configured to continuously obtain a plurality of sequential image frames contemporaneously in a same environment based on reflected light received through the object recognition window while driving the first light sources;
a processor configured to obtain a plurality of first values by performing a spatial domain signal processing operation on the plurality of sequential image frames, obtain a plurality of second values by performing a frequency domain signal processing operation on the plurality of sequential image frames, obtain one of the plurality of sequential image frames as a first reference image for optical object recognition associated with a first object based on the plurality of the first values and the plurality of second values, the first reference image being an image that does not include the first object, obtain another one of the plurality of sequential image frames as a first object image for optical object recognition associated with the first object based on the plurality of first values and the plurality of, second values, the first object image being an image that includes the first object; and
a memory configured to store the first reference image.
