  • Patent number: 10043304
    Abstract: Three dimensional image data is provided which includes data representing a first image which specifically may be a background image. A mixed image which is a combination of the first image and a second image which specifically may be a foreground image, a transparency map related to the mixed image comprising transparency values for pixels of the mixed image and a depth indication map for the mixed image comprising depth indication values for pixels of the mixed image. The use of a mixed image may allow three dimensional processing while at the same time allowing 2D backwards compatibility. Image quality around image objects may be improved by modifying transparency values in response to depth indication values and/or depth indication values in response to transparency values. Specifically, an improved alignment of transitions of depth indication values and transparency values may provide improved three dimensional foreground image object edge data.

  • Patent number: 8624964
    Abstract: A method and apparatus for rendering of image data for a multi-view display, such as image data for a lenticular auto-stereoscopic display, is disclosed. The method comprises the steps of receiving an image signal representing a first image, the first image comprising 3D image data, and spatially filtering the first image signal to provide a second image signal. The second image signal represents a second image, the spatial filtering being, e.g., a low-pass filter, a high-pass filter or a combination of a low-pass and a high-pass filter. A strength of the spatial filter is determined by a reference depth of the first image and a depth of an image element of the first image. The second image is sampled to a plurality of sub-images, each sub-image being associated with a view direction of the image.

  • Patent number: 8599313
    Abstract: A device and method for rendering content that includes analyzing previous and/or subsequent temporal portions of a content signal to determine elements that are positionally related to elements of a current portion of the content signal. The current portion of the content signal is rendered on a primary rendering device, such as a television, while the elements that are positionally related to elements of a current portion of the content signal are concurrently rendered on a secondary rendering device. In one embodiment, the elements that are rendered on the secondary rendering device may be rendered at a lower resolution and/or lower frame rate than the rendered current portion of the content signal. In one embodiment, at least one of previous and subsequent temporal portions of a content signal may be analyzed at a lower resolution than the content signal.

  • Patent number: 8325220
    Abstract: 2D image data are converted into 3D image data. The image is divided, on the basis of focusing characteristics, into two or more regions, it is determined to which region an edge separating two regions belongs. The regions are depth ordered in accordance with the rule that the rule that a region comprising an edge is closer to the viewer than an adjacent region and to the regions 3-D depth information is assigned in accordance with the established depth order of the regions. Preferably to each of the regions a depth is assigned in dependence on an average or median focusing characteristic of the region.

  • Patent number: 8289272
    Abstract: A display control system (11) comprises an input (12) for receiving an image to be displayed by means of a backlight (2) and a transmissive panel (3). A backlight controller (5) provides different colors or luminances for causing the backlight (2) to sequentially apply the different colors or luminances to the transmissive panel (3) in time-sequential sub-fields of the image. A transmissive panel controller (6) provides transmittivities for causing the transmissive panel (3) to sequentially apply the transmittivities to the transmissive panel in the time-sequential sub-fields of the image for displaying the image. The transmissive panel controller (6) selects a transmittivity based on a predetermined amount of off-axis gamma distortion of the transmissive panel.

  • Patent number: 8059133
    Abstract: A graphics pipeline (20) for rendering graphics receives texture data (22) and vertex data (23). The texture data (22) define rectangular texture maps (24), which are axis-aligned in texture space. The vertex data (23) describe output quadrilaterals (25) in screen space. A rasterizer (27) rasterizes the input rectangle (24) by determining which texels are inside the input rectangle (24). A mapper (28) maps the texels inside the input rectangle (24) onto the output quadrilaterals (25). The mapping is performed by calculating screen space output coordinates from the texture space grid coordinates of the texels. For the calculation an equation is used comprising at least one linear combination of the texture space grid coordinates of the texels inside the input rectangles (24) and at least one product of real powers of the texture space grid coordinates of the texels inside the input rectangles (24).

The image forming means has a planar array of light emissive display pixels arranged in rows and columns for producing a display, the display pixels being spatially defined by an opaque matrix. The image forming means may, for example, be a LCD display panel. The view forming module is configurable to function as a plurality of view forming elements arranged in the width direction of the display device, each view forming element focusing the light output from an adjacent group of the display pixels into a plurality of views for projection towards a user in respective different directions. The view forming module may, for example, be an array of lenticular lenses.
