    摘要: This disclosure provides systems, methods and apparatus including computer programs encoded on computer storage media for producing line multiplied images with better visual appearance. In one aspect, before lines of the image are multiplied, they are dithered with a noise signal that increases faster with higher frequency along the multiplied dimension of the image data than along the non multiplied dimension of the image. This results in a line multiplied image was improved image quality.

    摘要: A device for acquiring color images using a color filter array. The color filter array includes a pattern of red array elements, green array elements, and blue array elements. The red array elements and green array elements occur in the color filter array more frequently than the blue array elements. This multiplicity of red, green, and blue color filters adheres closely to known human visual system (HVS) chrominance and luminance responses. Also, the pattern has periodicity in the diagonal directions and is relatively immune to Moire artifacts that arise due to interference between periodic sampling patterns of the CFA and periodic features in imaged scenes.

    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 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.
