Problems solved by technology

[0003] Yet, when adopting mobile phone to play video in the prior art, mobile phone can only play video in full-screen fixed form, due to the restriction of the screen resolution of mobile phone, when causing high-resolution video to be played in low-resolution mobile phone, The video cannot be enlarged, so that some details in the high-resolution video cannot be displayed; when the low-resolution video is played on a high-resolution mobile phone, the video cannot be reduced, making the low-resolution video blurry
Therefore, when the mobile phone plays the video, the video screen is blurred

Embodiment 1

[0084] Such as figure 1 As shown, the embodiment of the present invention provides a flowchart of a video zooming method. The method is executed by a terminal, and the terminal has a touch screen function. The terminal may be a mobile phone, a tablet computer, or the like. The method includes the following steps:

[0085] Step 101, when the first video is displayed, the first operation is received, and the contact point is determined on the video layer according to the first operation;

[0086] Video is a series of still images displayed as a continuous picture through various technologies that use electrical signals to capture, record, process, store, transmit and reproduce. When continuous image changes exceed 24 frames per second, according to the principle of persistence of vision, the human eye cannot distinguish a single static image, so it appears to be a smooth and continuous visual effect.

[0087] The first operation is used to determine the contact point, which is...

Embodiment 2

[0173] Such as Figure 10 As shown, the embodiment of the present invention provides a video zooming device, including: a first determination module 1001, a second determination module 1002, a scaling module 1003, and a processing module 1004; the device has a touch screen function, and the device can be set on a terminal , the terminal can be a mobile phone, a tablet computer, and the like.

[0174] The first determination module 1001 is configured to receive the first operation when the first video is displayed, and determine the contact point according to the first operation on the superimposed playing video layer;

[0175] The first operation is used to determine the contact point, which is the center point of the area obtained when the user touches the display screen. This area can be an irregular area obtained by the user touching the terminal with a finger, or the terminal can be touched by a device such as a capacitive pen The obtained rule area. The first operation ...

Abstract

The invention discloses a method and a device for video zooming and relates to the field of communication network techniques. The method and the device for video zooming solve the problem that a high-resolution video cannot be zoomed in when the high-resolution video is played in low-resolution mobile communication equipment in the prior art, and also solve the problems that a low-resolution video cannot be zoomed out and the image of the video is obscure when the low-resolution video is played in high-resolution mobile communication equipment. When a first video is displayed, a first operation is received, and a contact point is determined according to the first operation; zooming multiples of the first video are determined according to a received second operation; the first video is zoomed according to the zooming multiples of the first video to obtain a second video; when a second size is greater than a first size, a third video is obtained and displayed according to the contact point, the first size and the second video; when the second size is not greater than the first size, the second video is displayed. The method and the device for video zooming, provided by the embodiment of the invention are applicable to zooming of played videos.

Description

technical field [0001] The present invention relates to the technical field of communication networks, in particular to a video scaling method and device. Background technique [0002] Today, with the rapid development of communication technology, people rely more and more on the use of mobile communication devices, for example, the mobile communication device may be a mobile phone. From the beginning, people used mobile phones to make calls and send and receive text messages, and now people can use mobile phones to surf the Internet to watch text messages and video playback. At present, when a mobile phone is used to play a video, usually the mobile phone opens the video to be played, and plays the video in a full-screen format. [0003] Yet, when adopting mobile phone to play video in the prior art, mobile phone can only play video in full-screen fixed form, due to the restriction of the screen resolution of mobile phone, when causing high-resolution video to be played in...
