Embodiment 1

[0034] refer to figure 1 , which shows a flow chart of the video image adjustment method in Embodiment 1 of the present invention, which may specifically include the following steps:

[0035] Step 101, acquire first video data collected by a camera of the first mobile terminal, and play the first video data in a first window of the first mobile terminal.

[0036] In a specific implementation, the embodiment of the present invention can be applied in a mobile terminal with a camera, for example, a mobile phone, a tablet computer, a personal digital assistant, a wearable device (such as glasses, a mobile phone, etc.) and the like. The camera is a piece of hardware on the mobile terminal. It can be configured on the front of the mobile terminal (also known as the front camera) or on the back of the mobile terminal (also known as the rear camera). In addition, the number of cameras can be a single , may also be two or more, and so on, which is not limited in this embodiment of th...

Abstract

The invention provides a video image adjustment method, a mobile terminal and a computer readable memory medium and relates to the technical field of video image processing. The method comprises the steps of obtaining first video data collected by a camera of a first mobile terminal; receiving second video data sent by a second mobile terminal; judging whether a first deviation angle parameter ofa first face image in the first video data matches a second deviation angle parameter of a second face image in the second video data or not; and adjusting and playing a second face image of the second video data if the parameters do not match. According to the embodiment of the invention, no matter an opposite end rotates the mobile terminal or rotates a face, an image can be adjusted only by obtaining the two deviation angle parameters through the mobile terminal, a visual angle of the face image displayed in an window and the visual angle of a video user are guaranteed to be uniform, and the experience effect of the user is improved.

Description

technical field [0001] The present invention relates to the technical field of video image processing, in particular to a video image adjustment method and a mobile terminal. Background technique [0002] With the convenience of using the Internet, video calls occupy a large proportion of social communication. Many people like to use video calls with relatives in different places during their breaks. Compared with ordinary calls, video calls shorten the distance between the two parties and increase the sensory experience. However, with the increase of working hours, many people like to make video calls when they are resting at night. When changing the position of the mobile phone or adjusting the posture during the video process, the display position captured by the camera will change, and it is likely that the faces of both parties will appear. The position of the user falls down, making the face in the image inconsistent with the perspective of the video user. It is neces...
