Abstract:
1. A method for identifying state of macro block of de-interlacing computing, adapted to an image processing apparatus, the method comprising: dividing a video frame into a plurality of regions, wherein each of the region comprises a plurality of macro blocks; providing a basic threshold corresponding to each of the regions according to a position of each of the regions in the video frame; identifying a first macro block to be one of a first type macro block and a second type macro block according to the basic threshold corresponding to one of the regions where the first macro block of the macro blocks locates, wherein the first type macro block is a dynamic macro block and the second type macro block is a static macro block; performing a corresponding de-interlacing computing step on the first macro block according to a result that the first macro block is identified as the first type macro block or the second type macro block; presetting a preset threshold, wherein the preset threshold is used to preliminarily determine the first macro block to be the first type macro block or the second type macro block: obtaining a threshold adjusting parameter corresponding to the preset threshold; and adjusting the basic threshold corresponding to one of the regions where the first macro block locates by using the threshold adjusting parameter.
