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.
