Abstract: In one embodiment, the system may receive a target pixel value for a pixel of an image of a series of images. The system may determine an error-modified target pixel value based on the target pixel value and a first error value. The system may generate a quantized pixel value corresponding to the error-modified target pixel value for display by the pixel of the image. The system may determine an aggregated representation of quantized pixel values displayed by the pixel of the image and corresponding pixels of one or more preceding images of the series of images. The system may determine a second error value based on the aggregated representation of the quantized pixel values and the first error-modified target pixel value. The system may dither at least a portion of the second error value to at least a corresponding pixel of a next image in the series of images.

Abstract: In one embodiment, a computing system may receive a target image with a first number of bits per color. The system may access masks that each includes dots associated with a grayscale range. A subset of the dots associated with each of the masks may be associated with a subrange of the grayscale range. The dots within the subsets of dots associated with the masks may have different positions. The system may generate a number of images based on the target image and the masks. Each of the images may have a second number of bits per color smaller than the first number of bits per color. The system may display the images sequentially on a display for representing the target image.

Abstract: Adjusted overlaid images are generated in response to at least one color reference object or color reference point.

Abstract: A display device may have multiple light emitter arrays. Each array may include multiple light emitters that emit light of a color. One or more of the arrays may have a reduced spatial resolution compared to other arrays as the size of the light emitters in the arrays with the reduced resolution may be larger than other light emitters. The display device may include one or more waveguides that converge light emitted from light emitters of different colors to form an image by overlapping the light at a spatial region. The display device may include an image processing unit that applies an anti-aliasing filter to reduce any visual effect perceived by users due to the reduced resolution in one or more color channels. The anti-aliasing filter may include convolution kernels that convolve input color values of different colors and may combine the convolution result for output color values of a color.

Abstract: Disclosed herein are display systems and techniques for operating a display in a display system. An output image is formed by scanning a column of light emitters such that emitters in different rows of the column contribute to a same location in the output image. The emitters are driven using pulse-width modulation (PWM). PWM pulses are applied in synchronization with the scanning to cause emitters to emit light at an intensity corresponding to an illumination parameter. The driving includes generating, based on an illumination parameter, a PWM pulse by applying an analog signal in combination with applying a digital signal. The analog signal controls an amplitude of the PWM pulse. The digital signal controls a duration of the PWM pulse.

Abstract: A display device has an image processing unit that determines an error for a pixel location that is based on the difference between an input color dataset and an output color dataset. The error is fed back to the image processing unit to propagate and spread across other neighboring pixel locations. In generating the output color values, the most significant bits (MSBs) and the least significant bits (LSBs) may be treated separately. The display device may extract the MSBs from the input and generate a first output color sub-dataset that is related to the MSBs. The display device may determine the LSBs from a difference between the input color dataset and the output MSBs. The display device may process the LSBs to compensate, adjust, scale, and quantize the values. The MSBs and LSBs may be re-combined to determine an actual color value displayed at the pixel location to determine the error.

Abstract: A display device has an image processing unit that determines an error for a pixel location that is based on the difference between an input color dataset and an output color dataset. The error is fed back to the image processing unit to propagate and spread across other neighboring pixel locations. In generating the output color dataset, an error-modified dataset that includes the input dataset and the error may first be generated. The error-modified dataset is examined to ensure the color values fall within the display gamut. The color dataset is also quantized and dithered to make the output dataset having a bit depth that is compatible with what the light emitters can support. Lookup tables and transformation matrices may also be used to account for any potential color shifts of the light emitters due to different driving conditions such as driving currents.

Abstract: A system for rendering color images on an electro-optic display when the electro-optic display has a color gamut with a limited palette of primary colors, and/or the gamut is poorly structured (i.e., not a spheroid or obloid). The system uses an iterative process to identify the best color for a given pixel from a palette that is modified to diffuse the color error over the entire electro-optic display. The system additionally accounts for variations in color that are caused by cross-talk between nearby pixels.

Abstract: The disclosed computer-implemented method for performing dithering in non-linear space may include receiving, as an input, a non-linear sRGB-encoded data stream that includes pixel data that is to be displayed on a display screen. The disclosed method may next include generating a dithering mask for the non-linear sRGB-encoded data stream. Still further, the method may include dithering the non-linear sRGB-encoded data stream using the generated dithering mask according to a scalar dithering algorithm or a vector dithering algorithm. The method may also include linearizing the dithered non-linear sRGB-encoded data stream for display on the display screen, and may include providing the linearized RGB-encoded data stream to the display screen for display. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: This disclosure provides systems, methods, and apparatus for generating images on a display. A multi-primary display can include control logic that converts input image data into the multi-primary color space employed by the display by mapping the input pixel values into the XYZ color space according to a gamut mapping function and then decomposing the XYZ tristimulus values into color subfields associated with the display's primary colors. For example, such a process can be used to covert image frames encoded in an RGB color space into a RGBW color space. In some implementations, the control logic can adapt the gamut mapping and/or the decomposition processes based on a saturation level of the image being processed.
