  • Patent number: 11115563
    Abstract: A method and apparatus obtains a source image having a plurality of source color gamut pixels in a source color gamut. The method and apparatus converts the plurality of source color gamut pixels to a plurality of corresponding target color gamut pixels using non-linear interpolation of a plurality of output pixel values from a reduced 3-D look-up table (LUT) for a target color gamut. The method and apparatus provides, for display, the plurality of target color gamut pixels (e.g., one or more pixels) on a target color gamut display.

  • Patent number: 11100889
    Abstract: Systems, apparatuses, and methods for reducing three dimensional (3D) lookup table (LUT) interpolation error while minimizing on-chip storage are disclosed. A processor generates a plurality of mappings from a first gamut to a second gamut at locations interspersed throughout a 3D representation of the pixel component space. For example, in one implementation, the processor calculates mappings for 17×17×17 vertices within the 3D representation. Other implementations can include other numbers of vertices. Rather than increasing the number of vertices to reduce interpolation error, the processor calculates mappings for centroids of the sub-cubes defined by the vertices within the 3D representation of the first gamut. This results in a smaller increase to the LUT size as compared to increasing the number of vertices. The centroid mappings are used for performing tetrahedral interpolation to map source pixels in the first gamut into the second gamut with a reduced amount of interpolation error.

  • Publication number: 20210201852
    Abstract: A system includes a display monitor compatible with a video specification having a reference EOTF while exhibiting an actual EOTF that deviates from the reference EOFT. The system further includes a video source subsystem operable to determine an approximated EOTF representative of the actual EOTF based on user input received from a display of at least one test pattern to the user via the display monitor. The at least one test pattern is intended to elicit input from the user based on a visual inspection of the at least one test pattern by the user. The video source subsystem further is to convert color values of each video image of a stream of images to corresponding non-linear codewords based on the approximated EOTF, and transmit the codewords to the display monitor for display as display images representative of the video images.

  • Publication number: 20210056635
    Abstract: The disclosed embodiments relate to automated generation of objective data for use in computing a forward interest rate for a future time period subsequent to a current date, as well as post validation thereof. Periodic sample sets of the prices of actual completed trades between anonymized parties of each of a set of interest rate futures contracts having consecutive expiration months which collectively include the selected future time period are obtained from an anonymized electronic trading system. The prices of current best offers to buy/sell each of those contracts are also randomly obtained. Each sample set, along with the randomly selected prices, is then processed to identify a subset thereof which are consistent with a relationship between the underlying interest rate of the set of contracts and time period covered thereby.

  • Publication number: 20200410748
    Abstract: In some examples, an apparatus obtains source layer pixels, such as those of a content image and first destination layer pixels, such as those of a destination image. The first destination layer pixels have associated alpha values. The apparatus obtains information that indicates a first blending color format for the alpha values. The first blending color format is different from a first destination layer color format for the first destination layer pixels and an output color format for a display. The apparatus converts the source and/or first destination layer pixels to the first blending color format. The apparatus generates first alpha blended pixels based on alpha blending the source layer pixels with the first destination layer pixels using the associated alpha values. The apparatus provides, for display on the display, the first alpha blended pixels.

  • Patent number: 10460889
    Abstract: A lockout device is presented to maintain an on/off switch lever of a disconnect box in a preferred position. A grasp portion of the lockout device that is in an unlocked position may be inserted in the on/off switch lever of the disconnect outlet box preventing the on/off switch lever from being moved from an off position to an on position, or vise versa. Once the grasp hook is inserted in the on/off switch lever, the lockout device can be moved to a locked position and secured with one or more padlocks to prevent the lockout device from being removed. A middle portion of the lockout device may be made of varying lengths to allow easy access to on/off switch levers of disconnect boxes located overhead, below the user's feet or in confined spaces without the requirement for ladders or other special access equipment.

  • Publication number: 20170084397
    Abstract: A method for forming a high aspect ratio sintered powder anode with low warpage, an anode made thereby and a cathode comprising the anode are provided. The method comprises placing a multiplicity of anode precursors on a forming substrate in a common plane wherein no more than 10% of the anode precursors are out of the common plane. A second substrate is then placed over the forming substrate with the anode precursors between the forming substrate and the second substrate thereby forming a sandwiched assembly. The sandwiched assembly is heated to a sintering temperature of the anode precursors thereby forming the sintered powder anodes. The and sintered powder anodes are removed from between the forming substrate and the second substrate.
