Patent Images
1. An iris recognition device comprising:
- a first lens and a second lens configured to capture images for recognizing an iris of a user;
a first filter configured to filter an image input via the first lens, and output a first signal;
a second filter configured to filter an image input via the second lens, and output a second signal; and
an image sensor including a plurality of sub-pixel groups which each include a plurality of pixels and are configured to receive the first signal and the second signal and output first image data and second image data that respectively correspond to the first signal and the second signal,wherein the first image data is obtained by photographing eyes of the user, andwherein the second image data is obtained by photographing a face of the user.
