Abstract
Disclosed are a self-adaptive adjustment method and device of a projector, and a computer storage medium. The method includes: acquiring a luminance average value of a current picture, and calculating an absolute value of a difference between the luminance average value and a preset normal luminance average value; simultaneously adjusting the projection luminance and the image luminance if the absolute value is greater than or equal to a first preset threshold value; only continuously adjusting the projection luminance if the absolute value is greater than or equal to a second preset threshold value and less than the first preset threshold value; only adjusting the image luminance if the absolute value is greater than or equal to a third preset threshold value and less than the second preset threshold value; forbidding the luminance adjustment if the absolute value is less than the third preset threshold value.
