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 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.

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.

摘要： Systems, methods and apparatus including computer programs encoded on computer storage media optimize display image quality under a variety of imaging environments. Dynamic frame streams such as those present in video applications may require a higher frame rate to adequately convey motion in the stream. A line multiplying image pipeline may be utilized for dynamic frames, which lowers the resolution of the displayed image. When dithering line multiplied images, a noise signal including asymmetrical high frequency components around zero frequency may be utilized. The display of static frames, such as photographs, may be achieved with acceptable image quality using a relatively lower display frame rate. Such a frame rate may enable the display of a high resolution image. A noise signal tailored for higher resolution, non line multiplied frames, such as a noise signal with symmetric high frequency components around zero frequency may be utilized for static frames.

摘要： This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for displaying high resolution images using an adaptive temporal dithering scheme on display devices having two or more color planes. The adaptive temporal dithering scheme includes identifying the dither visibility of an image to be displayed by the color planes and adaptively applying temporal dithering to the color plane having the highest dither visibility. In one aspect, temporal dithering can be adaptively applied between two different color planes on a frame-by-frame basis based at least partly on the dither visibility of the image content.

摘要： This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for performing color mapping in a display device. The display device (e.g., 40) can include a plurality of stored color mappings that are used to convert input digital color images into the display device's color space. Each of the stored color mappings can correspond to a distinct lighting environment.

For example, the display device (e.g., 40) may calculate an interpolated color mapping from two or more of the stored color mappings using interpolation weights that are based on the detected lighting conditions. The display device (e.g., 40) can then convert the input image using the composite color mapping, and display the image.
