摘要： Methods and data processing systems are disclosed for automatically calibrating display devices. In one embodiment, a data processing system includes a display device having a built-in image capturing device and a mirror system with at least one mirror that is operatively coupled to the image capturing device. The mirror system reflects one or more reference images in a first region of the display device and one or more references images in a second region of the display device to the image capturing device. The references images captured by the image capturing device allow a calibration of colors output from the display device. A reference image in the first region may be compared to different references images in the second region until a match is obtained. In another embodiment, an adjustable mirror system includes at least one adjustable mirror to allow adjustment of the mirror angle for the display calibration.

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 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 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： An automated RAW image processing method and system are disclosed. A computer receives a RAW image and metadata from a camera and interpolates an interpolated image from the RAW image so that the interpolated image is in a first color space. Predefined characterization matrices associated with the camera are obtained. Each of the characteristic matrices is associated with a different illuminant. A conversion matrix is interpolated from the characterization matrices and a white balance of the RAW image. The interpolated image is converted with the conversion matrix into a second color space. A resulting image in a rendered color space is produced from the converted image, and the resulting image is made available to an application program.

摘要： Successive frames or images of an input image that are presented to the output device are individually halftoned. A starting location within the input image for tiling one of one or more halftone techniques over the frame or image is determined. The starting location is then offset from the previously used starting location after a certain number of frames or images have been halftoned. Any halftoning technique may be used to halftone the frames or images. The halftoned frames or images are then viewed in a sequence in time.
