    摘要: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for reducing artifacts in an image generated by a display device. In one aspect, data is written to a display and a position of display elements is maintained based on the application of a bias voltage pattern. The bias voltage pattern includes alternating polarities along one dimension in a pattern having a first frequency spectrum, and alternating polarities along a second dimension in a pattern having a second frequency spectrum that is different than the first frequency spectrum. At least one of the first and second frequency spectrums may include a plurality of frequency components.

    摘要: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for tuning the white point of a display device. In one aspect, a display device includes a set of display elements configured to output light and electronics configured to drive the display elements. Each display element can have an on-state where a reflective surface can be positioned at a distance from a partially reflective surface such that the display element can reflect incident light. Each distance can be dependent on a bias voltage. At least one of the bias voltages for the display elements can be non-zero in the on-state, and one or more of the bias voltages may be adjustable to control a white point of the display device. The electronics can be electrically connected to the display elements to provide the at least one non-zero bias voltage.

    摘要: This disclosure provides implementations of dither-aware image coding processes, devices, apparatus, and systems. In one aspect, a portion of received image data is selected. First spatial domain values in the selected portion of the image data are transformed to first transform domain coefficients. Second spatial domain values in a designated dither matrix are transformed to second transform domain coefficients. A ratio of each of the first transform domain coefficients to a respective second transform domain coefficient is determined. The first transform domain coefficients are selectively coded in accordance with the determined ratios to define coded first transform domain coefficients. A reverse transformation is performed to transform the coded first transform domain coefficients to third spatial domain values defining a coded portion of the image data. By way of example, transformations such as discreet cosine transforms or discreet wavelet transforms can be used.

    摘要: This disclosure provides techniques related to halftoning video images for display on an electronic device. The techniques include adaptively selecting, on a pixel-by-pixel basis, between a mask-based dithering (MBD) and an error diffusion (ED) halftoning technique. The ED technique may be selected for halftoning pixels of an input frame of data having either a temporal change rate metric (CRM) or a spatial CRM exceeding a respective threshold. Where both the temporal CRM and spatial CRM are less than the respective thresholds, halftoning may be performed by the technique that produces a halftone value closer to a comparison halftone value of a comparison frame. The comparison frame may be a preceding frame, or an immediately preceding frame.

    摘要: This disclosure provides methods, apparatus, and computer programs encoded on computer storage media for tone based halftoning of digital images. By exploiting knowledge of local image features and tone levels, the halftoning method may be adaptively switched between error-diffusion and mask-based dithering with reduced boundary artifacts. By further utilizing a smart quantization error clipping scheme, artifacts inherent to the method of error diffusion are also reduced. The method consistently generates higher quality halftone images for both still and video applications when compared to conventional methods.
