摘要： The present disclosure relates to a vibrating mirror adjustment apparatus, system and method, and a projector. The vibrating mirror adjustment apparatus includes: an image feature acquiring module, an image identifying module, a resolution extracting module, and a vibrating mirror control module. The vibrating mirror adjustment apparatus identifies the category of the projected image and the resolution information corresponding to the projected image based on the acquired information feature of the projected image, then identifies whether vibration of the vibrating mirror is used to improve a resolution of an image, and further automatically controls the on or off state of the vibrating mirror, such that an optimal projection display effect is achieved, and visual enjoyment of a user is greatly improved.

摘要： Embodiments of the present application relate to the technical field of projection, and in particular, relate to a projection method and a projection device. The projection method includes: acquiring a projection image and an environmental image when a screen picture is projected to a projection region, wherein the environmental image includes an image when a predetermined projection screen picture is projected to the projection region or an image when no screen picture is projected to the projection region; regulating an aperture based on the projection image and the environmental image, wherein the aperture is configured to control a light flux projected to the projection region. Therefore, by adjusting the light flux, impacts caused by the stray light may be mitigated, and a relationship between projection contrast and luminance may be better coordinated, such that the projection contrast and luminance are effectively balanced and hence projection quality is improved.
