摘要： A method of reducing mosquito noise in a digital image. As mosquito noise is often most plainly visible in the "background" of an image (e.g., the sky or some other backdrop to objects within an image), the luminance value of the background of the image is first determined. Then, the luminances of the pixels of the image are compared against this "background luminance" to determine which should be considered as part of this background. The luminances of these background pixels are then averaged so as to smooth out the representation of the background, and reduce mosquito noise.

摘要： A method and system is provided for reducing mosquito noise in a digital image. The method and system receives an input luminance value for a first pixel in the digital image, and determines whether the first pixel is in relative close proximity to an object appearing in the digital image, based on a comparison of the variation between the input luminance value for the first pixel and luminance values of a first plurality of neighboring pixels. If the first pixel is in relative close proximity to an object, the method performs an average filtering of the input luminance value for the first pixel, based on the luminance values of a second plurality of neighboring pixels, to provide a filtered luminance value for the first pixel.

摘要： Systems and methods of processing pixel information associated with video image deinterlacing are disclosed. In one exemplary implementation, the method may include performing an edge adaptive interpolation process on a present field so as to determine whether an edge passes through a pixel, wherein the edge adaptive interpolation process provides edge data including a first intensity estimate for the pixel, receiving motion data associated with motion compensation processing, including an estimated motion vector for at least one pixel proximate to the pixel in at least one reference field, determining a second intensity estimate for the pixel as a function of the edge data and the motion data, and performing an intensity- calculation procedure, wherein an interpolated intensity of the pixel is calculated as a function of the first intensity estimate and the second intensity estimate.

摘要： A method and system for frame insertion in a digital display system is provided. The method is adapted for use with a liquid crystal display (LCD) type display and is effective to substantially reduce motion blur. The LCD display receives a sequence of digitized input frames at a first frequency. The method generates a sequence of output frames that include the digitized input frames interspersed with a plurality of modified frames. Each of the modified frames is substantially similar to a preceding digitized input frame, but has a reduced luminance. The modified frames may be generated by multiplying a preceding digitized input frame by a reduced luminance factor. The reduced luminance factor may be determined as a fixed value or as a function of an average pixel level of a preceding frame.
