    摘要: YCbCr image data may be dithered and converted into RGB data shown on a 8-bit or other bit display. Dither methods and image processors are provided which generate the banding artifact free image data during this process. Some methods and image processors may applying a stronger dither having a same mean with a larger variance to the image data before it is converted to RGB data. Others methods and image processors may calculate a quantization or encoding error and diffuse the calculated error among one or more neighboring pixel blocks.

    摘要: A display controller may include an RGB Interface module and a display port module, which may both use a target-master interface, in which the data receiving module pops pixels from the data sourcing module, and generates the HSync, VSync, and VBI timing signals. A dither module may be instantiated between the RGB interface module and display port module to perform dithering. The dither module may use a source-master interface, in which data signals and data valid signals are issued by the data sourcing module. In order to avoid having to use a large storage capacity FIFO with the dither module, a control unit may issue interface signals to the RGB Interface module and display port module, and clock-gate the dither module, to allow the data signals and data valid signals to properly interface with the RBG interface module and display port module, and provide data flow from the RGB interface module to the dither module to the display port module.

    摘要: A system improves the subjective impression of a digitized image displayed with a low amplitude resolution. The system digitizes an analog video signal with a first amplitude resolution. Before the amplitude resolution of the video signal is reduced to a second, lower amplitude resolution, the system adds a digital noise signal to the digital video signal. The maximum amplitude of the added digital noise signal is about equal to or smaller than the amplitude corresponding to the least significant bit of the second resolution.

    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: An image processing apparatus, an image transmission apparatus, a display, an image processing method and an image transmission method, capable of suppressing tone or gray-level distortion before and after dithering as well as reducing and then increasing the number of bit-planes of an image. An image processing apparatus comprises a first image processor for performing multi-level dithering based on a two-dimensional dither matrix to reduce the bit-plane number of a raster image as an original image, a memory for storing image data of the raster image whose bit-plane number has been reduced by the first image processor, and a second image processor for performing bit addition for the image data read out from the memory to increase the bit-plane number thereof. The first image processor applies to the multi-level dithering the sum of threshold values generated by a threshold generator and offset values generated by an offset generator for minimizing the difference between the signal value of the original image and the average of all the dither values of the raster image whose bit-plane number has been increased. A threshold matrix is obtained by changing matrix values of the two-dimensional dither matrix corresponding to matrix values of an offset matrix not being “0” (zero) to values other than their original values, respectively.
