摘要： A color display system providing reduced observer metameric failure for a set of target observers, comprising an image forming system having narrow-band primaries. A data processing system is used to implement a method for color correcting an input color image having input color values adapted for display on a reference display device having a plurality of input color primaries. A metamerism correction transform is applied to the input color image to determine an output color image having output color values in an output color space appropriate for display on the image forming system. The metamerism correction transform modifies colorimetry associated with the input colors to provide output color values such that an average observer metameric failure is reduced for a distribution of target observers.

摘要： A method for color correcting an input color image having input color values adapted for display on a reference display device having a plurality of input color primaries to account to provide reduced observer metemaric failure on a narrow-band display device. A metamerism correction transform is applied to the input color image to determine an output color image having output color values in an output color space appropriate for display on the narrow-band display device. The metamerism correction transform modifies colorimetry associated with the input colors to provide output color values such that an average observer metameric failure is reduced for a distribution of target observers.

摘要： Image data is transformed for display on a target display. A sigmoidal transfer function provides a free parameter controlling min-tone contrast. The transfer function may be dynamically adjusted to accommodate changing ambient lighting conditions. The transformation may be selected so as to automatically adapt image data for display on a target display in a way that substantially preserves creative intent embodied in the image data. The image data may be video data.

摘要： Signals are provided which allow colors in a wider color range than predetermined standards, which can be handled by apparatus according to such predetermined standards. A primary color converter converts first color signals having primary color points in a wider color range than the primary color points according to BT.709 into second color signals based on the primary colors according to BT.709. A photoelectric transducer converts the second color signals into third color signals according to photoelectric transducer characteristics defined in a numerical range wider than a range from 0 to 1.0 of color signals corresponding to a luminance signal and color difference signals according to BT.709. A color signal converter converts the third color signals into a luminance signal and color difference signals. A corrector incorporated in the color signal converter corrects the color difference signals into color difference signals.

摘要： An image sensor may have art array of image sensor pixels arranged in color filter unit cells each having one red image pixel that generates red image signals, one blue image pixel that generate blue image signals, and two clear image sensor pixels that generate white image signals. The image sensor may be coupled to processing circuitry that performs filtering operations on the red, blue, and white image signals to increase noise correlations in the image signals that reduce noise- amplification when applying a color correction matrix to the-image signals. The processing circuitry may extract a green image signal from the white image signal. The processing circuitry may compute a scaling value that includes a linear combination of the red, blue, white and green image signals. The scaling value may be applied to the red, blue, and green image signals to produce corrected, image signals having improved image quality.

摘要： An electronic device may have a camera module. The camera module may capture images. The electronic device may include image processing circuitry that color corrects the images. The image processing circuitry may desaturate the images globally and/or spatially based on global and/or spatial noise levels of the image. The image processing circuitry may desaturate the images substantially without changing the hue of the images. The image processing circuitry may generate a color correction matrix with constant hue in real time and may color correct images in real time as the images are captured by the camera module.
