Abstract: A method of motion detection using motion information of neighboring pixels, adaptive for determining whether a plurality of target pixels in a current field are moving pixels, is provided. First, it is determined whether a neighboring pixel in a previous field corresponding to the target pixel in the current field is the moving pixel. If the neighboring pixel in the previous field is the moving pixel, the target pixel is determined as the moving pixel and otherwise it is further determined whether the neighboring pixels around the target pixel in the current field are the moving pixels. If the neighboring pixels in the current field are the moving pixels, then the target pixel is determined as the moving pixel. Accordingly, the mistakenly judged static pixels can be found and modified to moving pixels, such that the accuracy of motion detection can be increased.

Abstract: A method for motion detection of a horizontal line is provided. First, a horizontal motion area of the horizontal line is detected according to differences between corresponding target scan lines in adjacent fields. Next, the horizontal line within a horizontal motion area in a current field and in a previous field are respectively detected. Then, the horizontal motion of the horizontal line is detected if the horizontal line is detected in both the current field and the previous field. Finally, pixels of the horizontal line in the current field are set as static pixels and data of the horizontal line is calculated through de-interlacing of corresponding horizontal lines in the previous field and in a next field if the horizontal motion of the horizontal line is detected. As a result, the flickers occurred in the generated field data can be removed and the quality of vision can be improved.

In the present method, when receiving video data encoded by a 4:2:2 sampling format, a plurality of filters having different weights are adaptively selected to convert the color components in the video data to a 4:4:4 sampling format based on the differences of luminance and color components among a target pixel and neighboring pixels thereof. Accordingly, the blurs occurred in an area with large color variation can be removed or reduced, such that the interpolated color components can be accepted by human eyes more easily.

In the present method, when receiving video data encoded by a 4:4:4 sampling format, color components of each set of neighboring pixels in the video data is down-sampled and a first difference of the color components between the video data before and after down-sampling in a down-sampling mode is calculated. Then, the color components of each pixel in the video data are truncated and a second difference of the color components between the video data before and after truncation in a truncation mode is calculated. The first difference and the second difference are compared and the down-sampling mode or the truncation mode that has a smaller difference is selected to compress the video data into a 4:2:2 sampling format.

First, a first threshold is given for determining whether the target pixels in the current scan line are moving pixels. Then, a number of moving pixels in a previous scan line of the current scan line is calculated and determined whether larger than a second threshold.

Abstract: 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.
