AI Technical Summary
Technical Problem
In existing technologies, ultra-high resolution videos, due to reduced resolution during playback, cannot effectively preserve details such as teaching equipment, resulting in a waste of resources.
Method used
By identifying key areas of the high-resolution input image, it determines whether the low-resolution output image retains details, and if necessary, overlays the sub-images that retain details onto the output image to form a clear video image.
Benefits of technology
Details such as teaching equipment can still be preserved in videos with reduced resolution, making full use of the value of high-resolution video capture equipment.

Abstract
本发明公开了一种视频图像帧处理方法、装置、设备及存储介质。其中，该方法包括以下步骤：针对当前输入视频的全幅图像，以及按预设分辨率由所述全幅图像缩小而成的第一输出图像，获取第一区域、第一识别结果和第二区域；根据所述第一识别结果判断所述第二区域内的内容是否清晰；在满足触发条件时，在全幅图像中对内容为不清晰的第二区域所对应的第一区域进行裁剪，得到第一子图像，将所述第一子图像叠加到所述第一输出图像中，形成第二输出图像，输出所述第二输出图像。通过本发明，观众可以在降低了分辨率的视频中观看到利用高分辨率视频采集设备采集到的细节，克服了分辨率后的视频无法展示高分辨率采集设备采集到的细节的缺陷。
