摘要： An apparatus and method for motion adaptive deinterlacing are provided. According to the method, a mean motion of a target pixel is obtained according to the target pixel and multiple neighboring pixels. A specific check area is obtained by setting the target pixel as a center and extending toward both sides of a first direction when the mean motion is higher than a first threshold value. The specific check area stops extending in reaching a pixel with a motion lower than a second threshold value. The second threshold value is lower than the first threshold value. The specific check area stops extending on a tail side of the first direction by reaching a first specific number of pixels from the target pixel. Combing of the specific check area is checked to determine a deinterlacing method for pixels within the specific check area.
