    Abstract: It is expected to provide an image display apparatus and image display method that can reduce the risk that an image quality is undermined due to a halo phenomenon caused by the leak of light passing through a non-corresponding color filter from a LED. The image display apparatus can respectively control luminous efficiencies of plural color LEDs, i.e., R-LED (11a), G-LED (11b) and B-LED (11c) that emit light through a color filter to a displaying unit. The image display apparatus obtains luminous efficiencies for a frame of RGB image signal (S2), calculates a light leak amount and then detects whether the halo phenomenon may occur or not (S3-S5). When the halo phenomenon is considered to occur, the luminous efficiencies of LEDs (11a, 11b, 11c) included in the liquid crystal display apparatus are controlled to make the light from the LEDs (11a, 11b, 11c) become close to white light (S8).

  • Publication number: 20110169823
    Abstract: An apparatus generates three dimensional image data. Specifically, image data for a first image layer and image data for a second image layer is generated together with depth indication data for at least one of the first image layer and the second image layer. The two image layers may be used e.g. for dependent images, such as foreground and background images, or for independent images, such as initial and final images for a cross fade. A dependency indicator which is indicative of a dependency between the image layers is generated and included in the three dimensional data. A rendering device may receive the three dimensional data and generate images for a three dimensional representation based on the data. The three dimensional processing is adapted in dependence on the dependency indicator. For example, interlayer de-occlusion processing may only be performed if the dependency indicator is indicative of dependent image layers.

    Abstract: A subject is imaged at a predetermined time interval by a plurality of imaging units which obtains a plurality of images having a parallax of a subject viewed from different viewpoints by imaging the subject from different viewpoints. An evaluation value which includes at least one of a luminance and a high frequency component of the images obtained by the imaging units at the predetermined time interval is calculated. When the evaluation value has changed by an amount exceeding a predetermined threshold value, the distance information calculation and three-dimensional processing on the plurality of images and object are performed. Here, a relative position of the object with respect to the three-dimensional image in a three-dimensional space is changed based on the distance information such that overlapping of the object and the three-dimensional image on top of each other is prevented when the three-dimensional display is performed.

The virtual world representation includes models of objects that specify the locations of the objects within the virtual world, the geometries of the objects, the dimensions of the objects, the surface representation of the objects, and/or other relevant information. By developing the virtual world representation, a number of image processing effects may be applied such as generation of stereoscopic images, object insertion, object removal, object translation, and/or other object manipulation operations.

    Abstract: Developable surfaces are generated by interactively evolving curves on a 2D surface embedded in 3D space using an iterative process to produce a model for the construction of a stylized three dimensional sculpture. Each iteration includes tessellating loops formed by the curves on the surface and unfolding the resulting tessellated strips onto a 2D plane. Collisions between the unfolded tessellated strips in 2D and between the loops in 3D are resolved, and the rendered evolved curve in 3D and tessellated strips in 2D are displayed simultaneously during the evolution. A graphical user interface allows the curve network, tessellated strips, and curve evolution parameters to be modified by a user. 2D textures may be mapped to the unfolded tessellated strips, and a set of tool paths may be output for cutting a 2D material.

  • Publication number: 20110169829
    Abstract: The invention provides techniques for wrapping a two-dimensional texture conformally onto a surface of a three dimensional virtual object within an arbitrarily-shaped, user-defined region. The techniques provide minimum distortion and allow interactive manipulation of the mapped texture. The techniques feature an energy minimization scheme in which distances between points on the surface of the three-dimensional virtual object serve as set lengths for springs connecting points of a planar mesh. The planar mesh is adjusted to minimize spring energy, and then used to define a patch upon which a two-dimensional texture is superimposed. Points on the surface of the virtual object are then mapped to corresponding points of the texture. The invention also features a haptic/graphical user interface element that allows a user to interactively and intuitively adjust texture mapped within the arbitrary, user-defined region.
