Abstract
A progressive displaying terminal and a video playing method and an image processing apparatus thereof are provided. The video playing method includes: extracting an odd field and an even field of each frame of an interlaced video, where the interlaced video has an initial resolution higher than a screen resolution of a progressive displaying terminal, and scaling the odd field and the even field of each frame respectively and then playing the odd field and the even field of each frame. In this way, the present disclosure eliminates the need of de-interlacing when playing an interlaced video on a progressive displaying terminal, so the hardware configuration requirements and the cost are reduced and a good picture quality is ensured during playing of the video.
