Abstract
A method and an apparatus for processing a video signal are provided. The method for processing a video signal includes: performing image processing of the video signal which contains no odd-even field information, and acquiring processed field image data; identifying and acquiring corresponding odd-even field information based on first field image data and second field image data continuous in time among the processed field image data; and performing deinterlace processing of the processed field image data based on the corresponding odd-even field information, thereby acquiring frame image data. In this way, the odd-even field information is identified from the image data in real time; the displaying effect of the video image will not be affected even though the fields are discarded, and the cost is low.
