A detection device includes a camera and a detector. The camera captures an image of a human face. The detector detects a position of a human eye based on the captured image output from the camera by template matching.

A 3D display device and the driving method for the 3D display device are provided. The 3D display device includes a liquid crystal display panel for monochrome display, and an electroluminescence display panel for color display disposed under the liquid crystal display panel; the electroluminescence display panel includes a plurality of regions arranged in a matrix, the plurality of regions form columns of bright regions and columns of dark regions, which are arranged alternately the liquid crystal display panel includes a plurality of first sub-pixels arranged in a matrix; each bright region of the electroluminescence display panel corresponds to at least two first sub-pixels adjacent in row direction of the liquid crystal display panel.

A viewpoint detector includes an imager that captures an image of an eye of a user and outputs the captured image, and a controller that detects a viewpoint of the user based on the captured image. The controller detects a position of the viewpoint from the captured image, and corrects the detected position of the viewpoint to a corrected viewpoint position with a conversion table.

An image display system includes a display, a barrier, a second mirror that has a changeable reflection angle for reflecting and projecting image light, a first controller that controls a change in the reflection angle, a camera that captures an image of a face of a driver, and a second controller that clips out a target area from a captured image output from the camera. The second controller shifts the target area as the first controller changes the reflection angle.

An auto-stereoscopic display device includes a display panel having an array of display pixels for producing a display; and a view forming unit having an array of view forming elements. Each view forming elements is configurable to focus the outputs of groups of the display pixels into views projected towards a user in different directions. The display device further includes a view deflecting unit to selectably change the directions in which the plurality of views is projected towards the user. The view deflecting unit includes at least one birefringent prism having a first refractive index for light having a first polarization direction and a second refractive index for light having a second polarization direction. The view deflecting unit further includes a polarization switch in registration with the birefringent prism for providing the birefringent prism with display light having the first or second polarization direction.

Provided are a three-dimensional (3D) rendering method and apparatus that detect eye coordinates of positions of eyes of a user from an image of the user, adjust the eye coordinates to correspond to virtual eye positions that reduce crosstalk caused by refraction of light; and perform 3D rendering of the eyes based on the adjusted eye coordinates.

An illumination unit of an embodiment of the present technology includes: an illumination optical system configured to generate illumination light; and a plurality of lenses configured to reduce a divergence angle of the illumination light. The illumination optical system includes: a light source (20) configured to apply light onto an end surface of one of a first substrate and a second substrate; and a light modulation layer (30) provided in a gap between the first substrate and the second substrate. The illumination optical system includes an electrode configured to generate an electric filed that generates, in the light modulation layer (30), a plurality of linear scattering regions (30B) in a three-dimensional mode, and to generate an electric field that generates, in the light modulation layer, a planar scattering region in a two-dimensional display mode. The lenses are arranged side by side in a direction in which the linear scattering regions extend, and are also arranged side by side in a direction intersecting with the direction in which the linear scattering regions extend.
