Vibrating mirror adjustment apparatus, system and method, and projector

A vibrating mirror adjustment system, comprising:

• a vibrating mirror adjustment apparatus, comprising:
• an image feature acquiring module, configured to acquire information feature of a projected image;
• an image identifying module, configured to identify a category of the projected image based on the information feature of the projected image;
• a resolution extracting module, configured to extract resolution information corresponding to the projected image based on the category of the projected image;
• an image comparing module, configured to acquire a comparison result between the resolution information of the projected image and a physical resolution of a projection display chip;
• and
• a vibrating mirror control module, configured to control an on or off state of the vibrating mirror based on the comparison result;
• and
• a vibrating mirror, a projection imaging lens, and the projection display chip, the vibrating mirror being disposed between the projection display chip and the projection imaging lens;
• wherein an on or off state of the vibrating mirror is controlled by the vibrating mirror control module;
• the projection display chip is configured to modulate an illumination light beam emitted by a projection illumination light source into an image light beam of a projected image;
• and
• the projection imaging lens is configured to amplify and shape the image light beam.
