  • Patent number: 9077978
    Abstract: This invention relates to capturing an image of a subject as a three-dimensional image using a single image-capturing apparatus. The image-capturing apparatus includes a first polarization means, a lens system, and an image-capturing device array having a second polarization means. The first polarization means includes first and second regions arranged along a first direction, and the second polarization means includes multiple third and fourth regions arranged alternately along a second direction. First region transmission light having passed the first region passes the third region and reaches the image-capturing device, and second region transmission light having passed the second region passes the fourth region and reaches the image-capturing device. Thus, an image is captured to obtain a three-dimensional image in which a distance between a barycenter BC1 of the first region and a barycenter BC2 of the second region is a base line length of parallax between two eyes.

  • Publication number: 20140062882
    Abstract: The present technique relates to a display control device, a method, and a program that can improve user's operability of a free-cursor type user interface. An imaging unit outputs an RGB image based on a pixel signal corresponding to a visible light among light input through a lens and an IR image based on a pixel signal corresponding to an infrared light among light input through the lens. An ROI set unit sets a movement area of an infrared light source in the IR image based on the RGB image, and a display control unit controls a cursor movement amount on a display unit according to movement of the infrared light source in the movement area. The present technique can be applied to a television set that monitors a viewing condition of a viewer, for example.
