1. An electronic device, comprising:
a first camera configured to capture a first image;
a second camera configured to capture a second image; and
a processor configured to
calculate a first distance of a first face position from a first edge of the first image and a first face size of a first face in the first image, and
compare the first face size with a first predetermined size range corresponding to the first distance to identify whether the first face is an ineligible object,
wherein a number of pixels of the second camera is smaller than that of the first camera, and
when the first face size is within the first predetermined size range, the first face is an eligible object.
