Problems solved by technology

[0004] Because in the existing video call method, the video area can only be enlarged simply through partial enlargement, and the overall bandwidth for transmitting video data is fixed, so the enlargement of the video region through the partial enlargement will reduce the Zooms in on the sharpness of the image in the video area, thereby degrading the user experience

Abstract

The present invention relates to the technical field of communications, and specifically relates to a video call method and a videophone. For use in a video calling process of acquiring a video transmitted by an opposite terminal of a video call over an established video transmission channel, the method comprises: acquiring a request parameter of a first area requiring enhancement within a first image frame, the first area being a confirmed partial area in the first image frame of the video; transmitting the request parameter to the opposite terminal of the video call; receiving a second image frame of the video transmitted by the opposite terminal of the video call via the video transmission channel, the second image frame of the video being acquired by the opposite terminal of the video call via a camera on the basis of the request parameter; and displaying the second image frame of the video. Employment of the present invention allows for enhanced display of the video image under the scenario in which the overall bandwidth for video data transmission remains unchanged.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a video call method and a video phone. Background technique [0002] With the rapid development of multimedia technology and telephone business, a single voice media communication method can no longer meet people's needs for communication in the information age, and people are eager to improve communication methods. Studies have shown that audio-visual is the most important means for people to obtain information, and 50%-60% of effective communication information depends on face-to-face visual effects, and only 33%-38% rely on voice effects. Videophone is a kind of telephone terminal capable of video communication. It can use the telephone network to transmit images and voice signals of both parties in real time in two directions, achieving the effect of face-to-face communication and realizing people's dream of hearing their voices and seeing their people during a call. ,...
