摘要： An apparatus for performing subpixel rendering of an RGBW display panel is provided. The apparatus receives an input gray level data to acquire a luminance value of each subpixel of a RGB pixel set including two RGB pixels adjacent to each other. The apparatus calculates a rendered luminance value of each subpixel of a display pixel set including two display pixels adjacent to each other according to the luminance values. The display pixel set of the RGBW display panel includes red, green, blue, and white subpixels. The rendered luminance value of the white subpixel of one of the display pixels is determined according to the saturation value of the corresponding RGB pixel and the luminance value of each subpixel of the corresponding RGB pixel. The apparatus acquires a gray level value of each white subpixel of the display pixel set according to the rendered luminance values.

摘要： Systems and methods for displaying super saturated color. Image data for display on a display or viewing device with a potential white luminance in a standard system with a maximum luminance is processed such that colors near the white point are reduced to a limited luminance. As the chroma of the displayed color is increased, a luminance attenuation is decreased. The scaling of the reduction is operable to be a linear function, a non-linear function, or any other function.

摘要： A system and method for converting raw frame data to a video file. Instead of converting all raw frame raw for each frame, embodiments create a mapping table and compare a mapping of the raw frame data for a current frame with a mapping of the raw frame data for a previous frame to determine if raw frame data changed from a previous frame to the current frame. Embodiments convert only the new raw frame data and update the mapping table with the new raw frame data, whereby the processing resources and time needed to convert raw frame data into a video file may be greatly reduced.

摘要： An object of the present invention is to reduce computation for color conversion processing on input RGB color signals with maintaining the hue of a picture expressed by the input RGB color signals. A color conversion processor of the present invention includes: a conversion unit that converts color data including multiple color components, which can be displayed in a first color gamut, to corresponding color data in a second color gamut, which is narrower than the first color gamut; a first color correction unit that corrects the converted color data by using a first color correction value; a first derivation unit that derives a first luminance correction value by multiplication using the first color correction value; and a first luminance correction unit that corrects the color data, corrected by the first color correction unit, by using the first luminance correction value.

摘要： Methods for piecewise-linear and piecewise-affine transformations for finger-angle and spatial measurement decoupling in user touch and gesture interfaces including those with multitouch capabilities are described. A calculation chain provides a first-order calculation of up to six touch parameters (left-right, front-back, downward pressure, roll angle, pitch angle, yaw angle) responsive in real-time to user touch on a touch-responsive sensor array. A piecewise-affine transformation is applied to these first-order calculations to produce parameter decoupling. The piecewise-affine transformation can be structured to depend only on current numerical values from the first-order calculation. Alternatively, the piecewise-affine transformation can be structured to additionally depend on the positive or negative direction of change over time of at least one numerical value from the first-order calculation, thereby providing a correction for hysteresis effects.

摘要： An electronic device has a display with a pixel array overlapping an array of temperature sensors. Control circuitry in the device may gather temperature measurements from the temperature sensor array. The control circuitry may apply a global offset to the temperature measurements and may apply a damping factor to the globally offset measurements to produce a two-dimensional temperature profile for the display. A look-up table or other data structure may be used to store information on pixel color correction gain values as a function of temperature. This temperature-gain information and temperature information from the two-dimensional temperature profile may be used by display circuitry in the device to display color-corrected images on the display.
