    摘要: Sub-pixel rendering with gamma adjustment allows the luminance of the sub-pixel arrangement to match the non-linear gamma response of the human eye's luminance channel. For each of a subset of input sampled data indicating a region of an input image, a gamma-adjusted data value is generated for each input image data value in the subset using a local average of at least two input image data values. A sub-pixel rendering operation uses the subset of gamma-adjusted data values and the subset of input image data values to produce an output data value for each sub-pixel element on the display panel. A plurality of output data values collectively indicates an output image. The gamma adjustment allows the sub-pixel rendering to operate independently of the actual gamma of a display device. The sub-pixel rendering techniques with gamma adjustment may improve image contrast in high spatial frequency portions of an image.

    摘要: A fixed cutter drill bit including a bit body having a plurality of primary blades extending radially from a bit center area, wherein the bit center area includes a partial connection between at least two of the plurality of primary blades. The fixed cutter drill bit further including at least one cutter disposed on at least one of the blades. Additionally, a method of designing a fixed cutter drill bit includes modeling the fixed cutter drill bit, the fixed cutter drill bit including a plurality of primary blades extending radially from a bit center area, wherein the plurality of primary blades includes a plurality of cutters. The method further including determining a center of an innermost cutter on each primary blade, creating a partial connection between the primary blades, and outputting the model of the fixed cutter drill bit.
