This disclosure provides micro-electro-mechanical scanning mirror control methods, control apparatuses, and systems. One example control method includes generating a control signal, where the control signal is used to control a micro-electro-mechanical scanning mirror to project, in a target scanning manner, lasers corresponding to pixels in a to-be-scanned image, to output a projected image of the to-be-scanned image. The target scanning manner includes a first scanning manner and a second scanning manner, and the first scanning manner and the second scanning manner have different initial locations in the to-be-scanned image. The control signal is sent to the micro-electro-mechanical scanning mirror. The to-be-scanned image is scanned in the first scanning manner and the second scanning manner, that is, from at least two different directions.
