Embodiment 1

[0019] figure 1 It shows the implementation process of the method for adjusting the screen light of the video call provided by Embodiment 1 of the present invention. For the convenience of description, only the parts related to the embodiment of the present invention are shown, and the details are as follows:

[0020] In step S101, the light sensitivity value of the imaging of the camera on the mobile terminal when the user makes a video call through the mobile terminal is acquired.

[0021] The embodiments of the present invention are applicable to mobile terminals, especially portable mobile terminals such as mobile phones and tablet computers, so as to facilitate users to use the mobile terminals to make video calls. In the embodiment of the present invention, the light sensitivity value represents the numerical value of the light intensity that the camera can perceive. When it is detected that the user uses the mobile terminal to make a video call, the light sensitivity va...

Embodiment 2

[0032] figure 2 The structure of the video call screen light adjustment device provided by the second embodiment of the present invention is shown. For the convenience of description, only the parts related to the embodiment of the present invention are shown, including:

[0033] The light sensitivity value acquisition unit 21 is configured to acquire the light sensitivity value of the camera imaging on the mobile terminal when the user makes a video call through the mobile terminal.

[0034] In the embodiment of the present invention, when it is detected that the user uses the mobile terminal to conduct a video call, the light sensitivity value acquisition unit acquires the light sensitivity value of the camera imaging on the mobile terminal, so as to detect in real time whether the picture of the video call is clear, so as to timely Get the light sensitivity value of the video image.

[0035] The first comparison unit 22 is configured to compare the light sensitivity value...

Embodiment 3

[0041] image 3 The structure of the video call screen light adjustment device provided by the third embodiment of the present invention is shown. For the convenience of description, only the parts related to the embodiment of the present invention are shown, including:

[0042] The first setting unit 31 is configured to acquire the standard video picture selected by the user, and set the standard light sensitivity value according to the light sensitivity value of the standard video picture.

[0043] In the embodiment of the present invention, before detecting the light sensitivity value of the video picture of the mobile terminal, the first setting unit sets the standard light sensitivity value of the video picture. Specifically, when setting the standard light sensitivity value, the standard video picture selected or specified by the user is received, that is, the video picture selected by the user can be used to evaluate the quality of the picture, the light sensitivity val...

Abstract

The invention applies to the technical field of a computer and provides an image light adjustment method and device for a video call. The method comprises the steps of obtaining an imaging photosensitive value of a camera on a mobile terminal when a user carries out the video call through the mobile terminal; comparing the photosensitive value with a preset standard photosensitive value; judging whether a difference value between the photosensitive value and the standard photosensitive value is in a preset range or not; and when the difference value between the photosensitive value and the standard photosensitive value is not in the preset range, controlling a light supplementary source to emit light with corresponding light intensity according to the difference value, thereby adjusting the image light of the video call. The image definition and stability when the video call is carried out through the mobile terminal are improved, and further the intelligence degree of the mobile terminal is improved.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a method and device for adjusting light in a picture of a video call. Background technique [0002] With the rapid development of science and technology, wireless communication technology is becoming more and more important to the development of the whole society, and more and more mobile terminals begin to have the function of video calling. Video calls have become an important way of contact in people's daily life. People often use mobile terminals to make video calls. However, when using mobile terminals to make video calls, the image of the video call is easily affected by the intensity of light. Even in the same light environment, Slightly changing the angle or orientation of the mobile terminal will greatly affect the effect of video imaging, for example, the picture becomes darker and the image is not clear. Contents of the invention [0003] The purpose o...
