Patent ID: 11928195
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G

Claim 6:
7. A method for recognizing an object in an electronic device, the method comprising:
obtaining at least one image using an image sensor;
recognizing an object in the at least one image;
calculating coordinates for transmission of directional beams having a first sequence based on the recognized object in the at least one image;
transmitting directional beams having the first sequence in at least one direction using the calculated coordinates, via an antenna array;
receiving reflected waves having a second sequence and reflected by the object, via the antenna array; and
recognizing a presence of the object based on the recognized object in the at least one image and amplitude patterns of the reflected waves corresponding to the object;
transmitting directional beams having the first sequence in the at least one send direction using the calculated coordinates via the antenna array for detecting liveness;
receiving reflected waves having the second sequence and reflected by the object via the antenna array; and
recognizing the liveness of the object based on the reflected waves for detecting the liveness,
wherein the recognizing of the liveness of the object comprises detecting micromovement of a specific portion of a face of a user.
