摘要： A video-rendering chip performs gain correction on received display input, based on a display temperature, to produce output values that are shown on the display. The video-rendering chip includes multipliers, a microprocessor, and a memory. The microprocessor receives a display temperature from a sensor, determines gain correction coefficients that correspond to the display temperature, and provides the correction coefficients to the multipliers. The multipliers then multiply the display input by the correction coefficients to produce the output values. The microprocessor may determine the correction coefficients utilizing a lookup table or a correction coefficient formula stored in the memory. The microprocessor may receive an updated display temperature periodically and may determine new correction coefficients that correspond to the updated display temperature. The microprocessor may receive updated display temperatures at fixed periods or at varying periods based on the previous display temperature.

摘要： 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.

摘要： A display and techniques for displaying information involve the use of pixel-generating elements that include a light conduit and multiple adjustable light absorbing filters. The light conduit allows light from a light source to pass from a first side to a second side of the pixel-generating element. A first adjustable light absorbing filter adjustably absorbs a first set of visible light wavelengths from light passing through the light conduit to produce a first filtered light. A second adjustable light absorbing filter adjustably absorbs a second, different set of visible light wavelengths from the first filtered light. Each adjustable light absorbing filter is adjustable to a substantially transparent state, and the pixel-generating element generates a viewable pixel having a color adjustable between substantially a color of the light source and a color of the light source as modified by one or both of the adjustable light absorbing filters.

摘要： A method for adjusting the characteristics of a display. The method for adjusting the characteristics of the display may include constructing color models as a function of a parameter such as temperature. Furthermore, the color model may be used to determine adjustment values to be applied to a display. The adjustment values may be organized in a table as a function of temperature and color values.

摘要： Methods and apparatuses for color correction of color device for various operating conditions. In at least one embodiment of the present invention, operating under a current condition, a color correction operation that is derived from color correction operations defined for other conditions is performed on the color data. In another embodiment, a device profile for managing colors for a color device operating under one condition is interpolated from the device profiles for the color device operating under other conditions (e.g., based on the input received from a user interface according to the perception of the user or based on the measurement of a sensor). The interpolation can be based on the input received from a user interface according to the perception of the user or it can be based on the measurement of a sensor or a set of sensors. Various operating conditions for a color device (e.g., a scanner, a camera, a video camera, a printer, a display device such as a CRT monitor or an LCD display panel, a television set, or others) include chromaticity and illumination of ambient light, background color for a display device, characteristics of print media for a printer, humidity, temperature, pressure and ink level for an ink jet printer, the age of a light source for a scanner, and others.
