  • Publication number: 20100201783
    Abstract: Influences of physiological stereoscopic elements are removed by image processing using projection transformation. A horopter-plane image projection unit 311 is designed to project a non-stereo image supplied via a signal line 129 onto a cylindrical plane (horopter plane) including a horopter circle. The size of the horopter circle is specified using, for example, the radius as horopter circle information. Additionally, the relationship with two eyes is specified by the interocular distance. A display surface right-eye projection unit 316 is designed to project an image projected on the horopter plane onto a display surface for the right eye. A display surface left-eye projection unit 317 is designed to project the image projected on the horopter plane onto a display surface for the left eye. Therefore, retinal images that are identical to each other are supplied to the two eyes to remove influences of physiological stereoscopic elements, and stereoscopic depth is given.

  • Publication number: 20100149321
    Abstract: An image processing apparatus includes an input unit, a computing unit, a determining unit, and a 3D image processor. The input unit receives filter width information indicating the vertical size of each line constituting a polarizing filter, as well as position correction information indicating positional misalignment of the polarizing filter. The computing unit computes determination regions for each pixel on the basis of the information. The determination regions are used to determine whether individual pixels constituting a 3D image to be output are contained in a right-eye or a left-eye image region. On the basis of the determination regions, the determining unit determines whether each pixel is contained in a right-eye image region or a left-eye image region. The 3D image processor creates a 3D image from a right-eye image and a left-eye image according to pixel positions determined on the basis of determination results.

  • Publication number: 20100091183
    Abstract: A video conversion apparatus includes: a video format conversion unit configured to interpolate, in the case that video signals, which are made up of a luminance component and color difference components and of which the video format is the interlace format, have been supplied, the luminance component and color difference components of the video signals, thereby converting the video format of the video signals into the progressive format; and a color difference format conversion unit configured to interpolate the color difference components of the video signals obtained with the conversion by the video format conversion unit, thereby converting the color difference format of the video signals from a first color difference format to a second color difference format that includes more color difference components than the first color difference format.

  • Publication number: 20100074521
    Abstract: An image processing apparatus includes: means for extracting, for each pixel of an image, a high-frequency component as focus information from a brightness signal for a neighboring pixel; means for integrating, for each pixel, the focus information on the neighboring pixel; means for replacing the focus information on each pixel with a value obtained using the focus information on the neighboring pixel greater than the focus information on that pixel to generate dark area focus information; means for integrating the brightness signals of each pixel and the neighboring pixel to extract an illumination component; means for calculating a depth value of each pixel using a coefficient based on the illumination component; means for normalizing the depth value of each pixel; means for controlling the normalized depth value using a tone curve; means for detecting a saturation of each pixel; and means for controlling the controlled depth value using the saturation.

  • Publication number: 20090041362
    Abstract: An image processing apparatus includes: a correlation value computing section that computes a correlation value between pixels in a noted image and its preceding and following reference images; a break determining section that determines a break in identical images based on the correlation value between pixels; a successive occurrence counting section that cumulatively counts successive occurrences of identical images as a successive occurrence count, if the noted image is not determined as corresponding to a break; a pattern determining section that determines whether or not the successive occurrence count and a set count match, if the noted image is determined as corresponding to a break; a matching counting section that counts up a matching count if it is determined that the successive occurrence count and the set count match; and a pull-down pattern detecting section that detects a predetermined pull-down pattern if the matching count exceeds a predetermined count.
