Patent number: 8917282Abstract: Techniques for improving the performance of vector-based, fluid motion simulation techniques. The techniques may be implemented in procedural painting algorithms that employ a vector-based, fluid motion simulation technique to help achieve dynamic, serendipitous behaviors of painting at good interactive rates even on relatively low-powered devices. Instead of employing polygons in a procedural painting algorithm that are combinations of pigment and water, a technique may be employed in which the polygons are separated into pigment polygons and water polygons. The water polygons are not rendered; only the pigment polygons are rendered. To improve the performance of the wetness determination at vertices of the pigment polygons, a technique may be used that first rasterizes all of the water polygons into a buffer, which may be referred to as a wetness layer or wetmap; the wetness at a vertex is then determined by sampling this buffer or layer at the vertex's position.Type: GrantFiled: August 26, 2011Date of Patent: December 23, 2014Assignee: Adobe Systems IncorporatedInventors: Stephen J.

Patent number: 8866839Abstract: A signal adapting chromacity system to control that may include a signal conversion engine to receive a source signal designating a color of light defined by a two spatial plus luminance dimensional color space, such as the xxY color space. The signal conversion engine may convert the source signal to a three dimensional color space defined within a subset gamut of a full color gamut, such as an RGW, RBW, or GBW color space. The subset gamut may include a first color light, a second color light and a high efficacy light. The signal conversion engine may perform a conversion operation to convert the source signal to an output signal, using the output signal to drive light emitting diodes (LEDs). The conversion operation may be a matrix, angular or linear conversion operation.Type: GrantFiled: July 31, 2013Date of Patent: October 21, 2014Assignee: Lighting Science Group CorporationInventors: Fredric S.

Patent number: 8861850Abstract: Systems, methods, and computer readable media for performing color correction operations to address memory color artifacts in a manner suited for real-time operations. In general, techniques are disclosed for correcting memory color rendering artifacts in an image without performing color space conversions. In one implementations, hue-saturation-value (HSV) image correction values may be expressed solely in terms of an image's base red-green-blue (RGB) color space values. Once expressed in this manner, color correction may be applied to the image directly—without the need to convert the image's color space into and out of a working color space (e.g., an HSV color space). As no color space conversions are necessary, the disclosed techniques are well-suited to real-time operations.Type: GrantFiled: January 31, 2012Date of Patent: October 14, 2014Assignee: Apple Inc.Inventors: Serhan Uslubas, David Hayward

Patent number: 8860747Abstract: System and methods for gamut bounded saturation adaptive color enhancement are provided. Color enhancement incorporating gamut bounded saturation enhances colors of an pixel from a source color gamut such that the resulting color is within a target color gamut. This resulting color may, for example, take advantage of an expanded target color gamut of a display. Gamut bounded saturation may be implemented independently or in combination with RGB bounded saturation.Type: GrantFiled: September 3, 2013Date of Patent: October 14, 2014Assignee: Marvell World Trade Ltd.Inventors: Vasudev Bhaskaran, Sujith Srinivasan, Nikhil Balram

Patent number: 8860750Abstract: Devices and methods for dynamic dithering are provided. For example, an electronic device according to an embodiment may include image processing circuitry that operates on higher-bit-depth image data and a display panel that displays lower-bit-depth image data. To obtain the lower-bit-depth image data, the image processing circuitry may perform dynamic dithering on the higher-bit-depth image data. Such dynamic dithering may involve dithering frames of the higher-bit-depth image data based at least in part on respective rounding threshold values.Type: GrantFiled: March 8, 2011Date of Patent: October 14, 2014Assignee: Apple Inc.Inventors: Brijesh Tripathi, Michael Frank

Publication number: 20140300624Abstract: A solution is proposed that performs global histogramming of pre-regionally-enhanced pixel values accounting for inter-regional illumination contributions to verify that over-saturation of an image is prevented. According to an embodiment, pixel values that have been regionally enhanced—that is, with applied gains calculated for the respective regions—are further added to illumination values corresponding to the pixel values, with the resultant summed pixel values being histogrammed again to determine the amount of over-saturated pixels. An over-abundance of over-saturated pixels results in a calculation of a global modifier applied to each pixel to reduce the number of over-saturated pixels below an acceptable threshold.Type: ApplicationFiled: April 4, 2013Publication date: October 9, 2014Applicant: NVIDIA CorporationInventor: David WYATT
