The invention discloses a projection control method applied to a projection controller, and the method comprises the steps: controlling a shooting module to shoot a projection plane image A comprisinga projection area, the projection plane image A not comprising a projection image; obtaining a color coordinate corresponding to a projection area in the projection plane picture A; adjusting the power supply configuration output by a projection module according to the color coordinates corresponding to the projection area in the projection surface picture A; and controlling the projection moduleto project the to-be-projected picture to the projection area according to the adjusted power supply configuration. By shooting a projection plane picture which does not comprise a projection pictureand obtaining a color coordinate corresponding to a projection area in the projection plane picture, and then adjusting the power supply configuration output by the projection module according to theobtained color coordinates, the display effect of the to-be-projected picture after being projected to the projection plane can be effectively improved, the projection picture abnormity caused by color mixing generated by the color of the projection plane is avoided, and the user experience is improved.
