Specifically, when the anti-candid camera works normally, the camera shoots a preset area to obtain a scene image, and the shot scene image is transmitted to an Artificial Intelligence (AI) processor, wherein the preset area comprises an area opposite to a display screen for displaying data to be protected, and the preset area is an area capable of shooting the display screen; the AI processor carries out image recognition on the scene image, judges whether the scene image contains target image elements or not, generates a control instruction according to a judgment result, sends the control instruction to the display controller, and the display controller acquires a corresponding display image from the memory according to the control instruction so as to control the display screen to carry out picture display.

For example, if the determination result indicates that the scene image includes the target image element, the control instruction indicates to stop displaying the data to be protected, and a warning interface may be displayed, where the target image element represents key information of a shooting behavior, such as a shooting posture and a camera device. The target image element may include an image of a specific person, or may include an image of an image capture device (e.g., an image of a camera); for another example, if the determination result indicates that there is no determination result and the AI processor is initializing, the control instruction indicates to display an initialization interface; for another example, if the judgment result indicates that there is a fault, the control instruction indicates to display an equipment fault interface; the display controller controls the display screen to display according to the control instruction, can control the display screen to display the data to be protected, can also control the display screen to stop displaying the data to be protected, and can also control the display screen to display other interfaces.
