A display device displays video for a virtual image. The display device includes a video generation unit generates image light representing the video, a concave mirror has a reflective surface on which the image light is reflected, and a support mechanism adjusts a position of the concave mirror. The concave mirror has, in each position on the reflective surface, a first radius of curvature in the first direction and a second radius of curvature in a second direction. The first radius of curvature and the second radius of curvature individually change and have different rates of change. The reflective surface has a shape following a partial region on an outer surface of an ellipsoid. The ellipsoid has a radius along the first direction that is greater than a radius along the second direction and a radius along a third direction orthogonal to the first direction and the second direction.

The information presentation device has an image acquisition unit, a parameter deriving unit, an abnormality detection unit, and the presentation unit. The image acquisition unit acquires a first image which is captured by a first imaging device and a second image which is captured by a second imaging device. The parameter deriving unit derives parameters for deriving three-dimensional coordinates from the first image and the second image. The abnormality detection unit determines presence or absence of an abnormality in a relative positional relationship or a relative relationship of pose between the first imaging device and the second imaging device according to the derived parameters. In a case where an abnormality is determined, the presentation unit presents warning information including an instruction that there is an abnormality.

An apparatus for processing an image, containing the 3D positional information of an object, realizes highly user-friendly and entertaining functions. The object image is presented on a display panel. When the user specifies a point on the panel screen, a real size of the object at the specified point is obtained in accordance with the 3D positional information. Then, a scale image substantially representing the real size obtained is generated, combined with the object image and a synthesized image is presented. The user is allowed to freely change the direction or location of the scale image.

The invention provides a range finder capable of carrying out three-dimensional measurement stably for a long period of time. A light pattern is projected on a subject by using a light source array unit in which a plurality of light sources, such as LEDs, are arranged. Even when each LED has a small light quantity, a sufficiently large quantity of light can be projected on the subject by the entire light source array unit, and hence, the three-dimensional measurement can be stably carried out. Also, a plurality of light patterns can be generated by electrically controlling a light emitting state of each LED of the light source array unit.

A plurality of iris images of a person to be authenticated in which the positions of extraneous light reflection are respectively different are captured by using an image capturing device. Iris codes, that is, features for authentication, are respectively extracted from the plural iris images, and the plural iris codes thus extracted are respectively compared with a registered iris code, so as to generate a plurality of comparison results. The plural comparison results are integrated to obtain an ultimate comparison score, which is used for the authentication.

The position of an eye is detectable with high precision from a face image of a person taken under near infrared illumination or the like. After pre-processing, the face image is subjected to brightness correction to increase the contrast between the sclera portion and iris portion of the eye. Brightness gradient vectors are calculated for the brightness-corrected image, and matching is performed between a brightness gradient image generated using the calculated brightness gradient vectors and an eye template. Further, matching with a pupil template is performed to correct the eye center position. Final positions of both eyes are then determined.
