摘要： An image processing system in which, in order to easily analyze input images acquired by sensors, output image quality is improved so that is suitable for a user. It includes: a gradient calculation unit that calculates a desired gradient based on input images; an indication function calculation unit that calculates an indication function for the input images, the indication function defining a range that can be taken by an output image and pixel values of a reference image; a pixel value renewal unit that renews pixel values of one of the input images so as to approximate the desired gradient to produce a renewed image; and a pixel value constraint unit that updates pixel values of the renewed image so as to fall within the range that can be taken by the output image and to approximate the pixel values of the reference image, to thereby obtain the output image.

摘要： An authentication device includes an image acquisition unit, an identification unit, and an authentication unit. The image acquisition unit acquires an image of an eye of a subject. The identification unit identifies the colored pattern of a colored contact lens worn by the subject by comparing a reference image with the image of the eye. The authentication unit identifies the subject, using a feature in a region other than a colored region of the colored pattern in the iris region of the eye.

摘要： An image acquisition unit (2) acquires an image obtained by capturing at least eyes of a target person. An object specifying unit (4) specifies an object in a line-of-sight direction of the target person using the acquired image. An incident light amount calculation unit (6) calculates an incident light amount representing an amount of light incident on the eyes of the target person using the acquired image. A reference pupil size determination unit (8) determines a reference pupil size based on the calculated incident light amount. A pupil size calculation unit (10) calculates a pupil size of the target person using the acquired image. An interest determination unit (12) determines an interest of the target person in the object by comparing the determined reference pupil size with the calculated pupil size.
