  • Patent number: 10573215
    Abstract: The present invention teaches a signal processing method and a signal processing device for simplifying TCON. The method includes the steps of: receiving a low voltage differential signaling (LVDS) signal and decoding the LVDS signal to obtain TCON signal width, period, and look-up table. The LVDS signal includes a clock signal and five data signals. TCON parameters are encoded in the empty differential pairs in the first bits of the last two data signals within continuous cycles. The TCON parameters include TCON signal width, period, and look-up table. By the present invention, TCON obtains TCON parameters from LVDS in a same sequence as they are stored in prior art's EEPROM. TCON resource is as such saved, and an external EEPROM may be omitted for lower production cost, under identical operation condition.

  • Patent number: 10565772
    Abstract: A graphics processing unit (GPU) processes graphics data using a rendering space which is sub-divided into a plurality of tiles. The GPU comprises cost indication logic configured to obtain a cost indication for each of a plurality of sets of one or more tiles of the rendering space. The cost indication for a set of tile(s) is suggestive of a cost of processing the set of one or more tiles. The GPU controls a rendering complexity with which primitives are rendered in tiles based on the cost indication for those tiles. This allows tiles to be rendered in a manner that is suitable based on the complexity of the graphics data within the tiles. In turn, this allows the rendering to satisfy constraints such as timing constraints even when the complexity of different tiles may vary significantly within an image.

  • Patent number: 9396515
    Abstract: One embodiment sets forth a method for transforming 3-D images into 2-D rendered images using render target sample masks. A software application creates multiple render targets associated with a surface. For each render target, the software application also creates an associated render target sample mask configured to select one or more samples included in each pixel. Within the graphics pipeline, a pixel shader processes each pixel individually and outputs multiple render target-specific color values. For each render target, a ROP unit uses the associated render target sample mask to select covered samples included in the pixel. Subsequently, the ROP unit uses the render target-specific color value to update the selected samples in the render target, thereby achieving sample-level color granularity.

Lenticular lenses (20) are set so that lenticular lenses are inclined at a predetermined angle to vertical direction of liquid crystal panel. Observer observes linear observation region (21) indicated by dotted line through lenticular lenses from predetermined viewpoint. Pixels of liquid crystal panel are parallelograms. Straight line connecting lower right vertex of target pixel to lower left vertex of immediately right pixel is angularly coincide with the observation region. In this way, straight line connecting lower right vertex of target pixel to lower left vertex of immediately right pixel angularly coincides with the lenticular lenses. Consequently, brightness on a screen visible through lenticular lenses becomes constant irrespective of position of observer, which results in reduced moire.

  • Patent number: 9245471
    Abstract: A multi-primary-color liquid crystal display device (100) according to the present invention includes a liquid crystal display panel (10) with a pixel made up of red, green, blue and yellow subpixels (R, G, B, Ye) and a signal conversion circuit (20) which converts an input three-primary-color video signal into a four-color video signal. If the three-primary-color video signal supplied to the signal conversion circuit is indicated as (r, g, b) using the grayscale levels r, g and b (each of which is an integer of 0 through 255) of the three primary colors of red, green and blue and if the luminance of the color white displayed by the pixel in response to a three-primary-color video signal indicated as (255, 255, 255) is supposed to be 100%, the signal conversion circuit adjusts the level of the four-color video signal so that when a three-primary-color video signal indicated as (186, 0, 0) is input, the luminance of the color red displayed by the red subpixel becomes equal to or greater than 6.5%.

    Abstract: A method for rendering polygons with a bounding box and a graphics processor unit. The method includes generating a bounding rectangle, wherein each edge of the bounding rectangle is defined to a sub-pixel precision. At least one polygon within the bounding rectangle is cropped to the sub-pixel precision. The polygon is blended with a background color outside the bounding rectangle to anti-alias the polygon with the background color, wherein the blending is performed with the sub-pixel precision of the bounding rectangle.

  • Patent number: 9030610
    Abstract: High definition media content processing techniques are described in which enhanced media content rendering techniques may be performed to output high definition media content. In an implementation, luma keying may be provided to define clear pixels in a composite output using an optimum set of graphics processing instructions. In another implementation, techniques are described which may provide clear rectangles in a composite output of one or more video streams. Clear rectangles to appear in the composite output are configured by a media playback application. A texture is arrived at to represent a union of each of the clear rectangles and is applied to form the clear rectangles in the composite output. In another implementation, capture techniques are described in which an image to capture is resolved as strips to an intermediate texture and then from the texture to a capture buffer in system memory.

  • Patent number: 9019299
    Abstract: A filtering method and apparatus for anti-aliasing takes advantage of improved existing hardware by using as input the data stored in the multisampling anti-aliasing (MSAA) buffers after rendering. The standard hardware box-filter is then replaced with a more intelligent resolve implemented using shader programs. Embodiments find scene edges using existing samples generated by Graphics Processing Unit (GPU) hardware. Using samples from a footprint larger than a single pixel, a gradient is calculated matching the direction of an edge. A non-linear filter over contributing samples in the direction of the gradient gives the final result.

  • Patent number: 9020299
    Abstract: Hybrid image format techniques are described in which multiple resolution images are concatenated to a standard bitmap image to create a hybrid image file. The hybrid image file is created through combining a relatively low resolution image with the additional images in a multi-frame format having higher resolution. The hybrid image file may contain data detectable to signal that higher resolution images are available in the hybrid image file. A hybrid aware application may be configured to detect and output a higher resolution image from the hybrid image file based on detection of the data. A legacy application that is not configured to detect the data may be unaware of higher resolution images contained in the hybrid image file, and accordingly outputs the relatively low resolution image.

  • Patent number: 9007389
    Abstract: Embodiments of the present invention are directed towards increasing texture filtering performance for texel components represented by more than 8 bits. As the number of bits per component increases, the number of texels that are processed each clock cycle decreases since more bits need to be processed to produce each filtered result. A filtered result may be accumulated over two or more iterations, with each iteration producing a portion of the filtered result. When only a portion of the components for each texel are used, the unused texel components are not processed. Elimination of unnecessary texel processing for unused texel components may improve texture filtering performance.
