摘要

随着网络音乐直播服务的发展，人们可以不去现场观看现场演出。然而，这样的现场音乐视频，尤其是那些由业余乐队成员录制的视频，缺乏存在感。因此，在之前的研究中，作者提出了一种通过对视频帧进行缩放来提高现场音乐视频的存在感的方法。它实现了增强存在感。然而，这也增加了观众的不适。这是因为缩放不是在音乐表演者身上进行的，而是在屏幕的中心进行的，这给观众带来了一种不自然的体验。因此，本文提出了一种新的放大方法，通过引入“主点”的概念，有效地突出了动作激烈的音乐表演者。通过实验的评价结果验证了所提出的方法提高了现场音乐视频的临场感，减轻了观众的不适感。

Improvement of Presence in Live Music Videos and Alleviation of Discomfort of Viewers by Zooming Operation

People can enjoy watching live performances without visiting live venues thanks to the development of live music streaming services on the Internet. However, such live music videos, especially those recorded by amateur band members, lack a sense of presence. Therefore, in the previous study, the authors proposed a method to improve the sense of presence in live music videos by performing zooming on the video frames. It achieved enhancing the sense of presence. However, it also increased the discomfort of the viewers. This is because the zooming was performed not on a music performer but in the center of the screen, resulting in an unnatural experience for the viewer. Therefore, in this paper, a new zooming method, which effectively emphasizes the music performer with intense movement, is proposed, introducing the concept of the “Main Spot”. The evaluation results through an experiment verified that the proposed method improved the sense of presence in live music videos and alleviated the discomfort of the viewers.
