Abstract: Embodiments of the present disclosure, provide a projection image anti jitter method and apparatus, and a projector. With the projection image anti jitter method, jitter data of a projection lens is captured; jitter characteristic information and offset data are acquired by calculation; and the projection image is adjusted based on the offset data.

Abstract: The present application relates to the technical field of digital projection and discloses a method and a system for adjusting projection dithering. The method includes follow steps: respectively setting a dithering parameter to at least two values within a preset value range, respectively acquiring projection images when the dithering parameter takes different values, calculating definition values of the projection images and obtaining a target dithering value according to the definition values of the projection images; and saving the target dithering value to an optical machine. In this way, the projection dither can be automatically adjusted to the optimal position according to the target dithering value, and the projection picture is more stable and clearer.
