ABSTRACT:
A compound-eye imaging device comprises a flash control means for controlling a flash unit to alternatively emit two kinds of near-infrared lights having different wavelengths while multiple single-eye images are read using a rolling shutter; a single-eye image reading means for reading, from the single-eye images, a single-eye image (hereafter “pre-change single-eye image”) imaged under a first illumination condition before an illumination condition change by the flash control means, and a single-eye image (hereafter “post-change single-eye image”) imaged under a second illumination condition after the illumination condition change; and an eye position detecting means for detecting eye positions in the single-eye images based on a comparison between the read pre-change and post-change single-eye images. This imaging device can further comprise: a face extracting means for extracting a face area based on the detected eye positions; and a personal identification means for performing personal identification based on the extracted face area.
