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： 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.

摘要： PROBLEM TO BE SOLVED: To provide an improved image processing method and system.
SOLUTION: The improved method and system involves edge-adaptive interpolation. The method uses a "9×2" window to detect the edge direction with post-processing to remove any artifacts due to possible false edge direction detection. A hierarchical scheme may be employed to reduce the computation required. The method determines if there exists an edge along the current pixel. To improve the edge detection precision, and also to remove the possibility of false edge direction detection, a post-processing technique is applied to the edge direction signal. After the edge signal post-processing, the edge direction information is then passed to the edge adaptive interpolation block to perform interpolation along the edge direction detected. Still another post-processing technique may be applied to the edge adaptive interpolated signal to further remove the possible noise due to an incorrect edge direction detection.

摘要： PROBLEM TO BE SOLVED: To solve problems concerning aliasing and other image artifacts which occur when the conventional image processing method and its system are used. SOLUTION: The disclosed method for edge adaptive interpolation includes a step for determining whether an edge is extended after passing a pixel or not. In the case of passing, a group of directions corresponding to the edge and, then, a specified direction can be determined. The method also comprises a step for obtaining the value of a parameter (e.g., luminance) concerning the pixel. In general, these operations generation of jaggies in an image. Moreover, it is possible to prevent easy generation of dot defects in the image by performing an arbitrary post-processing. The disclosed system includes a computer readable medium provided with a code which comprises an instruction to conduct the method. COPYRIGHT: (C)2004,JPO
