Abstract
The present disclosure relates to a method and an apparatus for recognizing an iris. The electronic device may include a camera configured to photograph the iris and a processor configured to perform iris recognition by using the photographed iris image, wherein the processor is further configured to determine a part of the iris image for the iris recognition has failed and re-perform the iris recognition for the determined part of the iris image.
Claims12
An apparatus for performing iris recognition, comprising:
- a camera module configured to photograph an iris image;
- and
- a processor configured to, in response to photographing the iris image:
- obtain an iris area of the photographed iris image;
- perform a first recognition process by comparing the iris area of the photographed iris image with a stored reference iris image, wherein:
- if the iris area of the photographed iris image matches the reference iris image, the processor is configured to output a recognition success message, and
- otherwise, if the first recognition process fails, the processor is configured to obtain a part of the iris area for which the first recognition process has failed in response to comparing each part of a plurality of parts the iris area with the stored reference iris image,
- perform a second recognition process by comparing the obtained part of the iris area with the reference iris image, and
- determine whether the iris recognition is successful based on the first recognition process and the second recognition process,
- wherein the obtained part of the iris area consists of remaining parts of the iris area other than a part of the iris area which matches the reference iris image in the first recognition process.

An operation method of an electronic device for performing iris recognition, the operation method comprising:
- obtaining a photographed iris image;
- obtaining an iris area of the photographed iris image;
- performing a first recognition process by comparing the iris area of the photographed iris image with a stored reference iris image, wherein:
- if the iris area of the photographed iris image matches the reference iris image, the method further comprises outputting a recognition success message, and
- otherwise, if the first recognition process fails, the method further comprises obtaining a part of the iris area for which the first recognition process has failed in response to comparing each part of a plurality of parts of the iris area with the stored reference iris image,
- performing a second recognition process by comparing the obtained part of the iris area with the reference iris image, and
- determining whether the iris recognition is successful based on the first recognition process and the second recognition process,
- wherein the obtained part of the iris area consists of remaining parts of the iris area other than a part of the iris area which matches the reference iris image in the first recognition process.
