Mobile terminal and method for partially amplifying far-end images in video call thereof

Abstract

The invention discloses a mobile terminal and a method for partially amplifying images in a video call thereof. The method comprises the following steps: determining a display area to be amplified in an image play area in a display screen in accordance with a user instruction; and amplifying the far-end images in the display area to be amplified to the amplified display area in accordance with the set amplified display area so as to cover the original picture play. The method for partially amplifying the videophone far-end images can maximally reduce image fault caused in the amplification process, and overcomes the difficulty that some partial details of the far-end images can not be watched clearly on a cell phone because of the limited display screen area of the existing videophone terminal in the current market. The mobile terminal users using the invention can timely capture some image information concerned by the users in the display screen by the videophone, thereby not only enriching functions of the cell phone, but also promoting videophone experiences of the users.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a mobile terminal and a method for zooming in on a remote image in a video call thereof. Background technique [0002] As 3G videophones gradually enter the lives of ordinary consumers, people can use videophones to communicate with voice and images conveniently. Users can see each other's expressions and the scene they are in, which facilitates better communication. [0003] The videophone of the mobile terminal adopts the 3G H.324M protocol stack specified by the 3GPP and is implemented through the CS circuit domain. When the user chooses to answer the videophone, the 3G H.324M protocol stack will be started, and the protocol stack will negotiate the videophone service through the H.245 message, confirm the logical channel, codec information, etc. After the videophone is established successfully, set the parameters according to the negotiation results, configure the cam...

Problems solved by technology

[0004] At present, due to the limitation of the volume of the mobile terminal, the display screen area of ​​the existing videophone mobile terminal on the market is limited. When watching a videophone or other video on a small-area display screen, sometimes it is impossible to see some parts of the image clearly. Local details, such as text information and information prompts displayed in the image, so a mobile terminal that can partially zoom in on the screen played by the mobile terminal is needed, so that users can capture certain information displayed on the screen that they care about in time , which can not only enrich the functions of the videophone, but also enhance the user experience
