Embodiment 1

[0029] This embodiment describes a scene where both parties in a video call display the other party's big picture, such as figure 1 As shown, it includes the following steps: S8, the sending end shoots a higher-resolution image; S10, performs layered processing on the image, and divides it into a background layer and a key presentation layer; S12, generates and transmits a relatively low-resolution background layer and key presentation layer images, and synthesize and display them at the receiving end; S14, gradually clarify the key presentation layer, and generate and display higher-resolution key presentation layer images at the receiving end; S16, relatively Freeze motion display and use picture-in-picture for low-resolution thumbnails.

[0030] like figure 2 As shown, wherein in step S14, the gradual clearing process for the key presentation layer includes the following steps: S142, dividing the untransmitted pixels in the key presentation layer into multiple frames, eac...

Embodiment 2

[0033] like Figure 4 As shown, the difference between the present embodiment and the first embodiment is that one of the two parties in the video call transmits the picture drawn or the written text on the electronic whiteboard to the other party. It includes the following steps: S6, the sending end selects the drawing board mode; S10, performs hierarchical processing on the image, and divides it into a background layer and a key presentation layer; S12', for the background layer, transmits the template number, and for the key presentation layer, generates and Transmit the image with lower resolution, call out the background template according to the template number at the receiving end, and synthesize and display it with the received image of the key presentation layer with lower resolution; S14, gradually clear the key presentation layer, and The receiving end generates and displays a higher-resolution key presentation layer image; S16', performs secondary layering on the k...

Abstract

The invention relates to an image displaying method in video calling. The method comprises the following steps: carrying out layered processing on an image to generate a background layer and a focused presentation layer based on division; transmitting an image with a lower resolution ratio or only transmitting a template serial number for the background layer and generating and transmitting an image with a lower resolution ratio for the focused presentation layer; carrying out combined displaying on the received low-resolution ratio background layer image and the received low-resolution ratio focused presentation layer image at a receiving terminal, or invoking a background template according to the template serial number at a receiving terminal and carrying out combined displaying on the background template and the received low-resolution ratio focused presentation layer image; and carrying out gradual clarified processing on the focused presentation layer image, and generating and displaying a high-resolution ratio focused presentation layer image at the receiving terminal. According to the invention, on the basis of layered distinguished treatment and processing, an image flow in the video call can be reduced to a proper extent without influencing enjoying of concerned portion watching by the user.

Description

technical field [0001] The invention relates to an image display method in a video call. Background technique [0002] With the popularization of 3G, 4G and even higher-speed wireless networks, video calls have increasingly become one of the common functions of mobile phones, and are expected to become the killer application of mobile phones in the 4G era. [0003] However, wireless video calling also has certain disadvantages. First, although the bandwidth of 3G and 4G is getting wider and wider, the billing model based on data traffic makes video calls expensive; second, the network is not always unimpeded. When the signal is poor or there are many users, Often results in poor video call image quality, thereby deteriorating user experience. Contents of the invention [0004] The purpose of the present invention is to solve the problem of poor video call image quality in the prior art under the condition of insufficient traffic and bandwidth, to provide an image display...
