Patent ID: 11908227
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. An optical object recognition method comprising:
driving first light sources among a plurality of light sources included in a display panel, the first light sources being disposed to correspond to an object recognition window which is a partial region of the display panel;
obtaining a contemporaneous plurality of sequential image frames based on reflected light received by an object recognition sensor through the object recognition window while driving the first light sources;
obtaining a plurality of first values by performing a spatial domain signal processing operation on the plurality of sequential image frames;
obtaining a plurality of second values by performing a frequency domain signal processing operation on the plurality of sequential image frames;
obtaining 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 first values and the plurality of second values; and
storing the first reference image; and
obtaining 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,
wherein the first reference image is an image that does not include the first object,
wherein the first object image is an image that includes the first object.
