Problems solved by technology

[0004] However, the network speed of the mobile cellular network will be unstable due to the change of the terminal location and the fluctuation of the surrounding signal; the bandwidth used by the video chat will drop due to downloading data or watching online video on the wireless network
When the network speed is lower than a certain threshold, the image data acquired by the camera cannot be sent to the receiving end in real time, resulting in incoherent video images received and output by the receiving end

Embodiment 1

[0024] figure 1 It is a flowchart of an image processing method for video chatting provided by Embodiment 1 of the present invention. This embodiment is applicable to video chatting on smart terminals, such as smart phones, smart watches, and tablet computers. The method can be implemented by In the video chat, it is executed as an intelligent terminal at the sending end, which specifically includes the following steps:

[0025] Step 110, acquire video chat image data in real time, where the image data consists of at least one frame.

[0026] When performing real-time acquisition, the terminal's own or external camera can be used to acquire image data. The image data of the video chat is the image data acquired by the camera from the start of the video chat to the end of the video chat. In order to ensure the continuity of the video chat picture, a preset number of frames can be obtained per second, for example, 25 frames per second. The size of each frame increases as the ...

Embodiment 2

[0038] The embodiment of the present invention also provides an image processing method for video chatting. As a further description of the method shown in Embodiment 1, before step 120, before performing sketch processing on the current frame according to the preset sketch parameters, the method also includes: include:

[0039] The preset sketch parameters are determined according to the current network speed, and the lower the current network speed is, the higher the preset sketch parameters are.

[0040] The current network speed is the absolute value of the current network speed. Each preset sketch parameter corresponds to a network speed range. The interval lengths of the network speed intervals corresponding to different preset sketch parameters may be the same or different. A corresponding relationship between preset sketch parameters and network speed is given below, as shown in Table 2, the value of the preset sketch parameters is an integer of 1-10.

Embodiment 3

[0069] The embodiment of the present invention also provides an image processing device for video chatting, which is used to implement the above method, and the device is applied to the sending end, such as Figure 4 As shown, the device shown includes:

[0070] An acquisition unit 41, configured to acquire image data of the video chat in real time, the image data consisting of at least one frame;

[0071] A sketch processing unit 42, configured to perform sketch processing on the current frame picture acquired by the acquisition unit 41 according to preset sketch parameters, to obtain a sketch image corresponding to the current frame picture, the preset sketch parameters and the current frame picture The degree of simplification of the lines in the sketch corresponding to the frame is proportional to;

[0072] The sending unit 43 is configured to send the sketch corresponding to the current frame obtained by the sketch processing unit 42 to the receiving end.

Abstract

The invention discloses an image processing method and an image processing device for a video chat, wherein the method comprises the steps as follows: obtaining image data of the video chat in real time, wherein the image data is composed of at least one frame; sketching the current frame according to a preset sketch parameter to obtain a sketch corresponding to the current frame, wherein the preset sketch parameter is in direct proportion to the line simplified degree in the sketch corresponding to the current frame; and transmitting the sketch corresponding to the current frame to a receiving end. The method and the device of the invention can be used for obtaining the sketch corresponding to the frame through sketching the frame. Because the number of the sketch is less than that of the frame, the network speed needed by transmitting the sketch to the receiving end is lower than the network speed needed by transmitting the frame. The method and the device of the invention can be used for timely transmitting the sketch with small data size to the receiving end under the network speed through adjusting the preset sketch parameter to control the data size of the sketch so that the receiving end can receive and output coherent sketch.

Description

technical field [0001] Embodiments of the present invention relate to image processing technologies, and in particular, to an image processing method and device for video chatting. Background technique [0002] With the continuous development of smart terminals (such as smart phones, smart watches, tablet computers, etc.), existing smart terminals can provide video chat functions. [0003] During video chatting, the intelligent terminal as the sender obtains image data through the front camera, and simultaneously obtains audio data synchronized with the image data through an audio input device such as a microphone; : The second generation mobile communication technology, 2G network or the third generation mobile communication technology, 3G network) or wireless network (such as wireless fidelity Wi-Fi) is sent to the receiving end to realize the real-time video chat function. [0004] However, the network speed of the mobile cellular network will be unstable due to the chan...
