Self-adaptive adjustment method and device of projector, and computer storage medium

A self-adaptive adjustment device of a projector, comprising:

• a computing module configured to acquire a luminance average value of a current picture when a user selects a luminance adjustment and calculate an absolute value of a difference between the luminance average value and a preset normal luminance average value;
• an adjusting module configured to:
• simultaneously adjust a projection luminance and an image luminance if the absolute value of the difference is greater than or equal to a first preset threshold value;
• continuously adjust the projection luminance if the absolute value of the difference is greater than or equal to a second preset threshold value and less than the first preset threshold value;
• adjust the image luminance if the absolute value of the difference is greater than or equal to a third preset threshold value and less than the second preset threshold value;
• and
• not adjust the luminance adjustment if the absolute value of the difference is less than the third preset threshold value;
• and
• a sending module configured to send self-adaptively-adjusted picture data to a projection module to perform projection.

A computer storage medium storing computer executable instructions that, when executed by an electronic device comprising a processor, cause the processor to:

• acquire a luminance average value of a current picture when a user selects luminance adjustment;
• calculate an absolute value of a difference between the luminance average value and a preset normal luminance average value;
• simultaneously adjust a projection luminance and an image luminance if the absolute value of the difference is greater than or equal to a first preset threshold value;
• adjust the projection luminance if the absolute value of the difference is greater than or equal to a second preset threshold value and less than the first preset threshold value;
• adjust the image luminance if the absolute value of the difference is greater than or equal to a third preset threshold value and less than the second preset threshold value;
• not adjust the projection luminance or the image luminance if the absolute value of the difference is less than the third preset threshold value;
• and
• send self-adaptively-adjusted picture data to a projection module to perform projection.
