Problems solved by technology
[0003] However, this type of video call application needs to transmit continuous video and audio data in real time, the amount of data to be transmitted is quite large, and relatively large network bandwidth will be occupied
Once the network bandwidth at the place where the caller is located is insufficient, it will cause the delay of the displayed video image or the degradation of the picture quality, etc., which is impossible for video call applications that have high requirements for display and call quality.

Embodiment Construction
[0039] The present invention applies the direct operation method of touching the screen to the selection and editing of the region of interest of the user in the video image, and quickly determines the region of interest according to the gestures operated by the user on the touch screen, and aims at Appropriate compression methods are applied to the region of interest and the region of non-interest respectively, so as to effectively reduce the overall data volume of the video image without affecting the content of the video image watched by the user.
[0040] figure 1 It is a flow chart showing a method for adjusting video image compression using gestures according to an embodiment of the present invention. Please refer to figure 1 , the method of this embodiment is applicable to an electronic device including a touch screen, such as a mobile phone, a personal digital assistant, a tablet computer, a notebook computer, a desktop computer, etc. , to compress the video image di...

The invention relates to a method for adjusting video image compression through a gesture. The method is suitable for compressing video images displayed by an electronic device which is provided with a touch screen. The method is that the video images are displayed on the touch screen,then, the touch screen is used for detecting a first touch operation executed by a user on the video images and determining an interest area and an non-interest area according to the first touch operation, and then, compression modes of the interest area and the non-interest area are adjusted and the touch screen is used for compressing the video images in the interest area and the non-interest area.
Description
technical field [0001] The invention relates to an image compression method, in particular to a method for adjusting video image compression using gestures. Background technique [0002] With the advancement of network communication technology, people today can conduct video conferences with multiple people through a web camera connected to a computer, or conduct video calls with others through a camera lens on a mobile phone. This face-to-face The communication method not only greatly shortens the distance between people, but also reduces the communication barriers that may exist in traditional voice conversations. [0003] However, the application of this type of video call needs to transmit continuous video and audio data in real time, the amount of data to be transmitted is quite large, and relatively large network bandwidth will be occupied. Once the network bandwidth at the place where the caller is located is insufficient, it will cause the delay of the displayed vid...
