Embodiment 1

[0068] in such as Figure 2a In the scenario shown, when the user looks like Figure 2bWhen moving to the left as shown, the position of the user's gaze on the screen of the mobile terminal also moves to the left accordingly. When the gaze position is judged according to the gaze position information along Figure 2c When the direction of the middle arrow moves to the left edge of the screen display area, control the camera of the mobile terminal to turn left, so that the mobile terminal can capture the scene on the left side of the scene, and the viewfinder image displayed on the screen of the mobile terminal will also move accordingly. Such as Figure 2d The screen of the mobile terminal shown shows the left side of the scene. When the user looks like Figure 2e When moving upward as shown, the position of the user's gaze on the screen of the mobile terminal also moves upward accordingly. When the gaze position is judged according to the gaze position information along ...

Embodiment 2

[0074] Embodiment 2 Determine whether the gaze stays at the certain position or is staring at a certain position according to the gaze position information and gaze duration information. When the gaze stays at a certain position, it means that the user starts to pay attention to this position, and then controls the camera to fix the position. Focus so that the position can be clearly displayed in the image on the screen. When the user's gaze stays at the position for a longer time, it is considered that the user is looking at the position. At this time, the camera is controlled to zoom in on the position, which is convenient for the user Viewing the scene at this position more clearly does not require the user to perform manual focusing and zooming operations, which greatly facilitates the user.

Embodiment 3

[0078] Embodiment 3 Judging whether the gaze movement trajectory matches the preset trajectory model according to the gaze movement trajectory information, and controlling the camera to zoom in on the displayed image on the screen when the gaze movement trajectory matches the preset trajectory model. There is no need for users to perform manual zoom-in operations, which greatly facilitates users and increases the diversity and flexibility of human-computer interaction.

Abstract

The invention relates to a camera control method. The camera control method includes acquiring eyesight information of users; controlling picturing of cameras according to the eyesight information. Picturing images of the cameras can change as changes of the eyesight information of the users without changing picturing positions or manual operation of the users, the users are greatly facilitated, and nature and friendliness of man-machine interaction are improved. The invention further discloses a device used for implementing the camera control method.

Description

technical field [0001] The present disclosure relates to the technical field of mobile communication, and in particular to a method and device for controlling a camera. Background technique [0002] When mobile terminals such as smartphones and tablet computers take pictures, the user adjusts the shooting angle by changing the shooting position; zooming in or out by sliding the touch screen to realize the magnification or reduction of the viewfinder image. The above-mentioned methods all require the user to perform manual adjustment or operation. When the user's hands are occupied, the above-mentioned operation is difficult to realize, which causes inconvenience to the shooting with the mobile terminal. [0003] Moreover, the above-mentioned operation method has certain defects in the naturalness and friendliness of human interaction, lacks an interactive feeling integrated with user behavior, and requires the user to perform too many additional operations. Contents of the...
