Method and device for amplifying video image

一种放大视频图像的方法及装置

Abstract

The invention relates to a method and device for amplifying a video image. The method comprises following steps of detecting a pressure value corresponding to a press operation when the press operation is received in the target display region of a display screen; generating a video window at a preset position of the display screen when the pressure value corresponding to the pressure operation is greater than a threshold value; amplifying the video image in the target display region to preset times; and displaying the amplified image in the video window. According to the technical scheme provided by the invention, the video window is generated at the preset position of the display screen, so that after the video image in the target display region is amplified to the preset times, the amplified image can be displayed in the video window. At this time, a user can watch the amplified video image of the target display region in the video window; the user can clearly watch the video image of the target display region in the video window; and therefore, the watching demand of the user is satisfied.
本发明是关于一种放大视频图像的方法及装置,该方法包括:在显示屏幕的目标显示区域接收到按压操作时,检测按压操作对应的压力值;在按压操作对应的压力值大于阈值时,在显示屏幕的预设位置上生成视频窗口;将目标显示区域内的视频图像放大至预设倍数后显示在视频窗口中。本发明提供的方案在显示屏幕的预设位置上生成视频窗口,以便于将目标显示区域内的视频图像放大至预设倍数后显示在视频窗口中。此时,用户便可以在视频窗口中观看放大后的目标显示区域内的视频图像,以使用户可以在视频窗口中看清目标显示区域内的视频图像,从而满足了用户的观影需求。
