Problems solved by technology

However, for a high-definition interlaced video with a resolution of 1920*1080 and displaying 25 frames per second, the processing capacity per second during deinterlacing processing is 1920*1080*25, such a huge processing capacity requires extremely high hardware configuration , leading to higher costs, and it is difficult to guarantee good image quality during video playback

Abstract

The invention provides a line-by-line display terminal, a video displaying method and an image processing device. The video displaying method comprises the following steps that each frame image of an interlaced video of the input line-by-line display terminal is zoomed, wherein the initial resolution ratio of the interlaced video is larger than the screen resolution ratio of the line-by-line display terminal, and the zoomed interlaced video is conducted interlacing-removal processing and then displayed. The hardware configuration requirement needed when the line-by-line display terminal is conducted interlacing-removal processing can be lowered, and the cost is reduced, and the good quality of the video when being displayed is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of terminal display, and in particular relates to a progressive display terminal, a video playing method thereof, and an image processing device. Background technique [0002] When a progressive display terminal plays an interlaced video, de-interlacing processing (De Interlace, DI) is required to improve or eliminate the original aliasing phenomenon of the video. At present, the progressive display terminal first directly performs deinterlacing processing on each frame of the interlaced video, and then scales and displays each frame of the processed image sequentially in order of playing time. However, for a high-definition interlaced video with a resolution of 1920*1080 and displaying 25 frames per second, the processing capacity per second during deinterlacing processing is 1920*1080*25, such a huge processing capacity requires extremely high hardware configuration , leading to higher costs, and it is di...
