1. 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
