Abstract: An authentication apparatus includes: an illumination device outputting light having a first polarization direction; a camera taking a first eyeball image, a second eyeball image, and a third eyeball image, of the user, which have a second polarization direction, a third polarization direction, a fourth polarization direction, respectively; and a control circuit. The control circuit (a) acquires cornea authentication information and iris authentication information, (b) generates an amplitude image, a phase image, and an average image, using the first eyeball image, the second eyeball image, and the third eyeball image, (c) authenticates a user ID corresponding to the average image, by referring to the iris authentication information, (d) authenticates a user ID corresponding to the amplitude image and the phase image, by referring to the cornea authentication information, and (e) determines a user ID corresponding to the user, using authentication results of the user ID in (c) and (d).

Abstract: A learning assistance device for a user to perform a learning task includes: a first concentration level estimator that estimates a first concentration level of the user, by analyzing information from an image capturing section that captures an image of a user; a second concentration level estimator that estimates a second concentration level of the user, by analyzing information which the user has actively input when performing a learning task; and a presentation switching section that switches between learning task content and between presentation schemes, based on at least one of the first concentration level or the second concentration level.

Abstract: An image synthesizing apparatus includes an illuminating device that outputs linearly polarized light having a first polarization direction and linearly polarized light having a second polarization direction, a camera that captures an image in a third polarization direction including a plurality of pixels and an image in a fourth polarization direction including a plurality of pixels, and a control circuit that synthesizes, on a pixel-by-pixel basis, the image in the third polarization direction and the image in the fourth polarization direction into an authentication image for iris authentication. The first, the second, the third and the fourth polarization directions are different from one another. The camera acquires the image in the third polarization direction using the linearly polarized light in the first polarization direction and acquires the image in the fourth polarization direction using the linearly polarized light in the second polarization direction.

Abstract: An embodiment of an image processing apparatus includes: an illuminating section which sequentially irradiates an object with a first and second illuminating light beams polarized in different directions. The section emits the polarized light beams sequentially so that the wavelength ranges of the light beams do not overlap with each other. The apparatus further includes: a polarization image sensor; a polarization mosaic processing section which obtains a first polarization image while the object is being irradiated with the first illuminating light beam and a second polarization image while the object is being irradiated with the second illuminating light beam; a depressed area detecting section which detects a depressed area on the surface of the object based on the polarization images; and an image forming section which forms an image representing the depressed area in an enhanced form.

Abstract: An image processing apparatus according to the present disclosure includes an illuminating section which sequentially irradiates an object with first and second illuminating light beams polarized in first and second directions. First and second polarization images are generated based on signals representing light transmitted through polarizers having the polarization transmission axis in respective directions that are parallel to, and intersect with, the first direction while the object is being irradiated with the first illuminating light beam, and third and fourth polarization images are generated based on signals representing light transmitted through polarizers having the polarization transmission axis in respective directions that are parallel to, and intersect with, the second direction while the object is being irradiated with the second illuminating light beam. A depressed object surface region is detected based on the first and second polarization images and/or the third and fourth polarization images.
