Abstract: A Personal Computer (PC) adjusts a color of an image received from a digital camera to produce an estimated reflectance spectrum and/or to convert the color to a new color space. First, an input compensation transform is generated, e.g. based on a Macbeth color chart in the image, to compensate for the sensitivity of the camera used to generate the image to different wavelengths of light and the illumination spectrum incident on an object of interest to which the image relates. In order to estimate the reflectance spectrum, a reflectance spectrum estimation transform is then generated by the PC. In order to convert the color of the image to the new color space, a color space conversion transform is generated by the PC. Both the reflectance spectrum estimation transform and the color space conversion transform are based on the input compensation transform and reference reflectance spectra stored in a reference reflectance spectra database.

The color correction table is stored in a color correction table storage section. The color correction execution section executes color correction along the color correction table so that the projector outputs a color with chroma no greater than the chroma limit.

Abstract: Embodiments of the present invention pixel processing system and method provide convenient and efficient processing of pixel information. In one embodiment, quotient-remainder information associated with barycentric coordinate information indicating the location of a pixel is received. In one exemplary implementation quotient-remainder information is associated with barycentric coordinate information through the relationship c divided by dcdx, where c is the barycentric coordinate for a particular edge and dcdx is the derivative of the barycentric coordinate in the screen horizontal direction. The relationship of a pixel with respect to a primitive edge is determined based upon the quotient-remainder information. For example, a positive quotient can indicate a pixel is inside a triangle and a negative quotient can indicate a pixel is outside a triangle. Pixel processing such as shading is performed in accordance with the relationship of the pixel to the primitive.

Abstract: Tuning sizes of cells of an interpolated lookup table may be performed based at least in part on an area specific behavior of a quality metric. A weighted input shaper curve may be determined to reduce interpolation errors in a multi-dimensional color lookup table. An initial input shaper curve may be applied to a color lookup table to create an interpolation result. The interpolation result may then be assessed for accuracy. The accuracy assessment may include comparing the interpolation result with a reference representation. An interpolation error may be calculated as the error between one or more intervals in a prospective color lookup table as compared to a reference representation. The weighted input shaper curve may be based at least in part on the calculated interpolation error.

Abstract: Systems and methods used for bilinear texture filtering may also be used to perform font filtering. Font data stored as a texture is read from memory in blocks that are coarsely aligned. Font alignment units may be used to provide a finely aligned region of the font data within a font filter footprint. The finely aligned region is then filtered using bilinear filtering to produce font coverage information representing a grayscale value for a pixel. Using existing bilinear filtering engines in conjunction with font alignment and sample units reduces the need for having a specific engine to perform each of the font filtering operations, possibly saving die area in a graphics system.

Abstract: This disclosure describes a graphics processing unit (GPU) pipeline that uses one or more shared arithmetic logic units (ALUs). In order to facilitate such sharing of ALUs, the stages of the disclosed GPU pipeline may be rearranged relative to conventional GPU pipelines. In addition, by rearranging the stages of the GPU pipeline, efficiencies may be achieved in the image processing. Unlike conventional GPU pipelines, for example, an attribute gradient setup stage can be located much later in the pipeline, and the attribute interpolator stage may immediately follow the attribute gradient setup stage. This allows sharing of an ALU by the attribute gradient setup and attribute interpolator stages. Several other techniques and features for the GPU pipeline are also described, which may improve performance and possibly achieve additional processing efficiencies.

The system involves a video driver, which may include commercially available hardware, such as a graphics accelerator card. The method involves identifying the edges of a tessellated image represented by compound shapes, redefining the triangles that have a side shared with one of the edges, and defining a new plurality of triangles, which are added to the redefined triangles.

Each rendering device computes a (2D) image in response to the objects assigned to it, including computing multiple overlapping images and using a graphics processor to blend those images into a resultant image.

This has the effect that the resultant images include transparency information sufficient to combine them using transparency blending.

The method may be embodied as a computer program that controls the operation of a processor. Accordingly, processors, computers, and systems that render images of digital objects in accordance with the method are also disclosed.

Abstract: A multi-threaded graphics processor is configured to use to extrapolate low resolution mipmaps stored in physical memory to produce extrapolated texture values while high resolution nonresident mipmaps are retrieved from a high latency storage resource and converted into resident mipmaps.

Abstract: Techniques are described for processing computerized images with a graphics processing unit (GPU) using a unified vertex cache and shader register file. The techniques include creating a shared shader coupled to the GPU pipeline and a unified vertex cache and shader register file coupled to the shared shader to substantially eliminate data movement within the GPU pipeline. The GPU pipeline sends image geometry information based on an image geometry for an image to the shared shader. The shared shader performs vertex shading to generate vertex coordinates and attributes of vertices in the image. The shared shader then stores the vertex attributes in the unified vertex cache and shader register file, and sends only the vertex coordinates of the vertices back to the GPU pipeline. The GPU pipeline processes the image based on the vertex coordinates, and the shared shader processes the image based on the vertex attributes.

Abstract: A display color-correcting system is provided. Color response values are measured that go into the vertices of polyhedra in a cubic color output space of the display. A set of corresponding values for the display is built from intermediate values determined between the measured color response values. The intermediate values are determined by decomposition and interpolation of interpolation volumes in the cubic color output space. Each of the interpolation volumes is the combined volume of a selected polyhedron within the cubic color output space and a predetermined volume of space between the selected polyhedron and the next polyhedron within the cubic color output space. The set of corresponding values is converted into decoupled RGB adjustment values that specify the RGB signals independently for the display to produce corrected colors. The RGB adjustment values are saved into one or more look-up tables.

Abstract: A programmable system for dithering video data. The system is operable in at least two user-selectable modes which can include a small kernel mode and a large kernel mode. In some embodiments, the system is operable in at least one mode in which it applies two or more kernels (each from a different kernel sequence) to each block of video words. Each kernel sequence repeats after a programmable number of the blocks (e.g., a programmable number of frames containing the blocks) have been dithered. The period of repetition is preferably programmable independently for each kernel sequence. The system preferably includes a frame counter for each kernel sequence. Each counter generates an interrupt when the number of frames of data dithered by kernels of the sequence has reached a predetermined value. In response to the interrupt, software can change the kernel sequence being applied. Typically, the system performs both truncation and dithering on words of video data.

In a first example embodiment, a method for automatic upsampling of a demosaicked image includes several acts. First, a demosaicked image and an edge-orientation map that was created during the creation of the demosaicked image are received.

Next, an interpolation direction is determined for each pixel in which upsampling of the demosaicked image should be performed using the upsampled edge-orientation map. Finally, missing pixels in the upsampled image are estimated by performing interpolation along the interpolation direction using available pixels surrounding each missing pixel location.

Abstract: An improved attribute determination process allows the sharpness of a surface attribute function to be adjusted on a per-object, per-surface, per-texture, per-function, or other appropriate basis. A computer-based animator then can selectively adjust the sharpness or other attribute(s) of portions of a to-be-rendered image without significantly increasing the rendering time. For a selected texture, corresponding sampling regions will be shifted about the respective surface points projected in texture space. A multi-dimensional set of sub-regions can be generated for the shifted sampling region. Bounding boxes can be determined for each sub-region, the boxes occupying less area, such as in texture space, than a single bounding box for the original sampling region. The bounding boxes can be used for local attribute determinations (such as texture lookups) for each sub-region, with the local attributes being processed to determine an attribute for the respective surface point.

In AFP architecture systems, the input and output LUTs and profiles may each be incorporated in appropriate Color Conversion CMRs. The preferred size is determined as a reduced size that requires less computation to generate but does not cause loss of accuracy in conversion between the input and output color spaces.
