The utility model discloses a dustproof motor, which comprises a motor body and an electrostatic adsorption mechanism arranged on the motor body and used for adsorbing small particles in the motor body. The electrostatic adsorption mechanism comprises a conductive unit and a dust sticking unit covering the surface of the conductive unit. According to the utility model, through the synergistic effect of active electrostatic adsorption and passive dust-sticking fixation, the limitation of the traditional motor dust-proof technology is broken through, the POG imaging problem caused by the fact that small particles fall on a BG is avoided, and the imaging quality and the reliability of the camera module are remarkably improved.

This disclosure provides a power control method, an image processing method, an apparatus, an electronic device, and a medium, relating to the field of electronic device technology. The method is applied to an electronic device, which includes an image acquisition component and a Time-of-Flight (TOF) component. Specifically, the method includes: acquiring the distance between the image acquisition component and the object being acquired when the image acquisition component is in an on state; and adjusting the transmission power of the TOF component based on the distance. The power control method provided in this disclosure can adjust the transmission power of the TOF component according to the distance between the image acquisition component and the object being acquired. This eliminates the influence of reflected light from the TOF component on the image acquisition component when the distance is close.

This invention provides a sliding control light assembly for a car sun visor magnetic vanity mirror with stepless color temperature adjustment and brightness scaling. It includes a mirror panel, symmetrically arranged dual-sided backlight assemblies, corresponding PCB circuit boards, dual-color LED beads (warm and cool), two independent sliding adjustment modules, and a control and drive unit composed of an MCU main control chip and a constant current drive circuit. The backlight adopts a three-layer side-entry structure consisting of a light guide plate, a reflective film, and a diffuser film. The two sliding adjustment modules are located on opposite sides of the PCB, independently controlling color temperature and brightness respectively. A Hall sensor unit is integrated on each side of the PCB. The advantages of this invention are: dual-sided independent sliding control enables continuous stepless adjustment of color temperature and brightness across the entire range, without any level gaps; the side-entry thin backlight provides uniform light output, suitable for the limited installation space of sun visors; the Hall sensor enables magnetic opening and lighting, providing high reliability through non-contact triggering; the dual-channel constant current drive eliminates flicker, has a built-in parameter memory function, and is suitable for low-voltage automotive power supply environments.
