Electronic device and method for displaying image for iris recognition in electronic device

A method for displaying an image for iris recognition in an electronic device, the method comprising:

• selecting an image for representing eyes from a memory of the electronic device;
• activating an iris recognition function;
• in response to activating the iris recognition function, capturing an image using a camera;
• identifying an eye included in the image captured by the camera;
• identifying a first image corresponding to a first distance among a plurality of pre-stored images when a distance between the eye and the electronic device is the first distance;
• displaying the first image, the first image being different from the eye included in the image, when the distance between the electronic device and the eye included in the image captured by a camera is a first distance;
• identifying a second image corresponding to a second distance among the plurality of pre-stored images when the distance between the eye and the electronic device is the second distance;
• changing the first image into the second image obtained by differently processing at least one or more of a shape, clarity, transparency, brightness, color, or object size of the first image and displaying the second image associated with the first image when the distance between the electronic device and the eye is the second distance different from the first distance;
• and
• performing authentication using an iris image and the eye included in the image captured by the camera when the distance between the electronic device and the eye included in the image captured by the camera is a distance within an iris-recognizable range.

A non-transitory computer readable medium including a program that, when executed by at least one processor, is configured to cause the at least one processor to:

• select an image for representing eyes from a memory;
• activate an iris recognition function;
• in response to activating the iris recognition function, capture an image using a camera;
• identify an eye included in the image captured by the camera;
• identify a first image corresponding to a first distance among a plurality of pre-stored images when a distance between the eye and an electronic device is the first distance;
• display the first image, the first image being different from the eye included in the image, when the distance between the electronic device and the eye included in an image captured by a camera is a first distance in the electronic device;
• identify a second image corresponding to a second distance among the plurality of pre-stored images when the distance between the eye and the electronic device is the second distance;
• change the first image into the second image obtained by differently processing at least one or more of a shape, clarity, transparency, brightness, color, or object size of the first image and display the second image associated with the first image when the distance between the electronic device and the eye is the second distance different from the first distance;
• and
• perform authentication using an iris image and the eye included in the image captured by the camera when the distance between the electronic device and the eye included in the image captured by the camera is a distance within an iris-recognizable range.
