For example, the present invention can use the characteristics of the wave width modulation mechanism to control the ON and OFF bandwidth of the exposure member 31 through different duty cycles during a fixed pulse wave period. Ratio, and achieve the effect of power saving. For example, a larger duty cycle means that the longer the exposure time of the exposure element 31 is, the more power it consumes. Therefore, the duty cycle can be reduced to save power consumption. On the other hand, by adjusting different pulse wave frequencies, the blinking speed of the exposure member 31 can be affected, and different interference effects can be generated.

According to a specific embodiment of the present invention, the blinking modes include a high-frequency blinking mode, an intermediate-frequency blinking mode and a low-frequency blinking mode, and a user can switch between the modes by using a physical button or a switch.

Specifically, if the power detection module 34 detects that the real-time power information of the power supply module 21 is greater than 80%, the exposure member 31 is set to the high-frequency flashing mode (as shown in FIG. 6), and the exposure effect is the highest at this time. If the real-time power information is between 50% and 80%, the interference signal module generating module 33 switches the exposure member 31 to the intermediate frequency flashing mode (as shown in Figure 5); If the real-time power information is lower than 50%, the exposure member 31 is adjusted to a low-frequency flicker mode (as shown in FIG. 4) to further save power consumption. However, the value of the real-time power information of the electronic device 1 corresponds to the high-frequency, intermediate-frequency, or low-frequency flicker mode of the exposure member 31, and can be set according to actual needs, and is not limited thereto. Alternatively, in other embodiments, a long light mode and more flashing mode segments of the exposure element 31 may be further added, so that the user can achieve a balance between exposure and power consumption according to actual needs.

According to the idea of the present case, by switching the exposure member 31 to operate in the high-frequency flicker mode, the intermediate-frequency flicker mode, and the low-frequency flicker mode according to the power of the electronic device 1, not only can the privacy be protected and the power consumption of the exposure member 31 can be saved. According to a specific example of the present invention, when the exposure member 31 is turned on and operating, the user can press the button 231 again to allow the activation module 32 to turn off the exposure member 31. At this time, the user can normally use the photographing device 10 for a video conference or Take a picture.
