  • Publication number: 20130249976
    Abstract: An image display panel includes: an image display unit including pixels arranged in horizontal and vertical directions, and displaying a composite image including different images; and an image separating unit facing the image display unit, and separating the composite image into the different images using light-transmitting portions transmitting light and light-shielding portions shielding the light. Each of the pixels includes sub-pixels each including a light emitting region, the sub-pixels have sizes different from sizes obtained by equally dividing the pixel, the light-transmitting portions are open in a diagonal direction, and each of boundary lines between the light-transmitting portions and the light-shielding portions is determined by moving parallel a continuous line that connects lines each connecting gravity centers of adjacent sub-pixels or adjacent light emitting regions in the sub-pixels, or to be a continuous line that connects lines each connecting midpoints of the gravity centers.

  • Patent number: 8531448
    Abstract: A deviation amount of a pictographic character portion of “G” is calculated based on a description of a file, and left eye-use display data (ABCDEF GIJK) and right eye-use display data (ABCDEG HIJKL) in a portion (b) in FIG. 3 are generated. A starting location of a description of “ABCDEFGHIJKL” is specified by an X coordinate and a Y coordinate described in the file. In addition, a process of alternately writing pixel data constituting the left eye-use display data (ABCDEF GIJK) and pixel data constituting the right eye-use display data (ABCDEG HIJKL) from a pixel data storing location of a VRAM corresponding to the coordinates (that is, one right eye-use pixel and one left eye-use pixel are alternately written one after another in a horizontal direction as a display image) is carried out.

  • Publication number: 20130229710
    Abstract: The present application relates to a display apparatus comprising: a display portion which displays a first image and a second image different from the first image to create a stereoscopic image; a separator which separates the first and second images from each other; and an adjuster which adjusts a shape of the separator. The separator includes a barrier portion which blocks image light emitted from the display portion. The barrier portion includes a contour portion which defines a shape of at least one opening that allows transmission of the image light. The contour portion includes a first contour and a second contour facing the first contour. The first and second contours define a continuous opening region inclined at a predetermined angle from a vertical line. At least one of the first and second contours forms protrusions which periodically protrude toward the opening region. Shapes of the protrusions are heterogeneous.

  • Patent number: 8526712
    Abstract: A three-dimensional sense adjusting unit displays three-dimensional images to a user. If a displayed reaches a limit of parallax, the user responds to the three-dimensional sense adjusting unit. According to acquired appropriate parallax information, a parallax control unit generates parallax images to realize the appropriate parallax in the subsequent stereo display. The control of parallaxes is realized by optimally setting camera parameters by going back to three-dimensional data. Functions to realize the appropriate parallax are made into and presented by a library.

  • Patent number: 8217991
    Abstract: A stereoscopic image processing method capable of preventing occurrence of undesirable cutout of image when a stereoscopic combined image is printed out is provided. A stereoscopic combined image can be created and recorded using a digital still camera 1. This stereoscopic combined image is a single image formed by arranging a plurality of view-point images. At first, left view-point image data and right view-point image data are stored in a memory by performing photographing twice. Then, the data of the two images are arranged laterally into a single image. Through this processing, original stereoscopic combined image data is created. Padding areas (dummy areas) are added to the original stereoscopic combined image data at the upper and lower sides thereof. Namely, a processed image containing the original stereoscopic combined image is created.
