Audio and video recording device for foreign language teaching

Abstract

The invention discloses a recording and video recording device for foreign language teaching. According to the invention, the local video content is integrated and processed to the lower part or one side of the overall video content; Therefore, the whole video content and the local video content can be placed in the same display screen, the contents which are mainly explained by teachers and the global content can be displayed together, a video learner can learn more visually, and self-learning is clearer. During video recording, important capture can be carried out on contents explained by teachers, the capture mode is simple and reliable, targeted video recording can be automatically carried out on teaching contents, and the effect of automatic audio and video recording is achieved; Teachers' explanation contents are convenient to detect, and coarse tuning and fine tuning are adopted, so that the angle of the camera can be accurately and quickly adjusted, and the video recording effect is ensured.

Description

technical field [0001] The invention relates to the technical field of recording for foreign language teaching, in particular to a recording and video recording device for foreign language teaching. Background technique [0002] At present, for foreign language teaching, there are more and more applications of video teaching. Video teaching has many advantages, especially for some self-learners, its cost is low and time is free. The current video teaching is generally to upload the teacher's video. However, although the current teacher's teaching video is generally a combination of audio and video, although the continuous development of high-definition camera technology can basically meet the requirements, but for some key vocabulary , words or key sentences, when explaining, the current camera is generally a distant view, which makes it difficult to clearly and zoom in on some key words, words or sentences, especially the positions that the teacher focuses on when explainin...

Problems solved by technology

The current video teaching is generally to upload the teacher's video. However, although the current teacher's teaching video is generally a combination of audio and video, although the continuous development of high-definition camera technology can basically meet the requirements, but for some key vocabulary , words or key sentences, when explaining, the current camera is generally a distant view, which makes it difficult to clearly and zoom in on some key words, words or sentences, especially the positions that the teacher focuses on when explaining. It is difficult to record all-round video with long-range photography, and if the camera is zoomed in, it will cause the overall view to be invisible. For video learning, it will lose sight of the other and affect the understanding of the entire context
