摘要： An apparatus and a method for motion adaptive de-interlacing with chroma up-sampling error remover are provided. Wherein, a motion detector determines moving pixels and static pixels in a target scan line. A first CUE remover and a second CUE remover remove the CUE of the target scan line in the previous field and the CUE of the adjacent scan lines in the current field, respectively. A de-interlace unit de-interlaces the adjacent scan lines to obtain a de-interlaced second scan line. A selector selects output data of the first CUE remover or the de-interlace unit as data of the target scan line according to a result of motion detection of the motion detector. A merging unit merges the adjacent scan line output by the second CUE remover and the target scan line output by the selector to output two scan lines of an output field.

摘要： A method of image processing and a device thereof are provided in the present invention. First, an image having a plurality of regions is received, wherein each region comprises a plurality of pixels. A contrast process is performed on each region and a respective local curve of each region is analyzed, wherein the local curve is a corresponding relation between the gray-level values of the pixels in each region before and after the contrast process. Next, the gray-level value of one of the pixels in a boundary between one of the regions and the neighboring region is adjusted according to the respective local curves of the one of the regions and the neighboring region. The local contrast process towards to each region is performed for enhancing the image. Therefore, not only can the features be obvious, but the non-uniform area in the boundary between the regions also can be smoothed.

摘要： A direction-adaptive image upsampling system and method using double interpolation is disclosed. Each of double interpolation (DI) units with different interpolation functions receives an input image and generates a corresponding double-interpolated image and an associated double-interpolated difference. A decision unit receives the double-interpolated differences from the DI units for deciding the DI unit that has an optimal interpolation around a pixel under process. An adaptive selector selects the double-interpolated image associated with the DI unit having the optimal interpolation as an output image.
