Abstract: A multi-region imaging device (1000?, 2000) and method (9000?). The multi-region imaging device (1000?, 2000) comprises: a picture light projection plate (1100?, 2100?), wherein the picture light projection plate (1100?, 2100?) comprises a first region (1110?, 2110?) and a second region (1120?, 2120?) that do not overlap each other, the first region (1110?, 2110?) and the second region (1120?, 2120?) emit picture light for imaging; and an optical path compensation section (1200?, 2200?), wherein the optical path compensation section (1200?, 2200?) is arranged on a propagation path of the picture light emitted by the second region (1120?, 2120?), and the picture light emitted by the second region (1120?, 2120?) is transmitted by the optical path compensation section (1200?, 2200?) and optical path compensation is carried out thereon.

Abstract: The present disclosure provides a projection adjustment system and method, and a projection color adjustment system and method. The projection adjustment system comprises an illumination module, a projection module, and a variable diaphragm control module, wherein the illumination module casts light carrying imaging information, wherein the projection module obtains the light carrying the imaging information and then casts it outward to a projection plane, wherein the variable diaphragm control module comprises at least one variable diaphragm and a controller, and wherein each variable diaphragm adjusts at least one diaphragm aperture of the variable diaphragm under the control of the controller, and the light intensity of the light cast outward is adjusted by reducing or enlarging the diaphragm aperture.

Abstract: An optical lens assembly includes a lens unit and a holder. The lens unit includes at least a front lens and a rear lens, and the holder includes a positioning portion and a holding portion extended downwardly the positioning portion. The positioning portion and the holding portion are integrated with each other. The holding portion forms a light chamber for holding the lens unit therein, wherein the light chamber allows imaging lights to enter thereinto and pass through the lens unit. The positioning portion is sealed on the outer surface of the front lens along the outer periphery of the front lens.
