Embodiment Construction

[0029] As shown in Figure 1, the present invention proposes a method for improving the display quality of high-definition video images by using image enlargement processing technology to upgrade high-definition video images of a certain resolution to higher-resolution high-definition video images, thereby improving the video effect The role of the work is as follows:

[0030] 1. Obtain original interlaced high-definition video data through high-definition video image acquisition equipment. In the present invention, the resolution is 1280×720i, the color format is YV12, and the high-definition video image with a frame rate of 25 / 30fps is an example;

[0031] 2. The top field and the bottom field of each frame of the original video data are image-enlarged (for example, enlarged by 1.5 times), and then merged into one frame, so that the image frame rate remains unchanged, so the available resolution is 1920× 1080i, color format is YV12, high-definition video image with a frame r...

Abstract

This invention provides a method for increasing display quality of high definition video image by image amplification and process including: 1, getting high definition video data of original interlaced scanning by a high definition video image collection device, 2, carrying out image amplification to the top and bottom fields of the frames of the data then merging them to one, in this way, the frame rate of images keeps unchanged and the resolution is increased, carrying out color space conversion to the amplified video image to strengthen color information of the image, and the converted video image is transmitted to a high definition video display device to be displayed harmlessly by HDMI interface synchronized by an accurate timer.

Description

technical field [0001] The invention relates to the technical field of video images, in particular to a method for improving the display quality of high-definition video images. The method aims to improve the display quality of high-definition video images by using video image processing technologies such as image enlargement. Background technique [0002] Digital video is divided into ordinary definition video, standard definition (referred to as SD) video and high definition (referred to as HD) video. Ordinary-definition video mainly corresponds to the resolution of the existing VCD; standard-definition video mainly corresponds to the resolution of the existing TV, and its image quality is at the studio level; and the resolution of high-definition video can reach 1920×1080p, which is the current common analog The definition of the TV screen is three times that of the DVD, and the picture effect makes the DVD eclipsed; in addition, the aspect ratio of the display screen of ...
