PROJECTION DEVICE, PROJECTION SYSTEM AND METHOD FOR ADJUSTING PROJECTION BRIGHTNESS OF PROJECTION SYSTEM

摘要

The present disclosure provides a projection device, a projection system and a method for adjusting projection brightness of the projection system. The method includes: projecting, by a projection unit of each projection device, an image on a projection plane corresponding to the projection unit separately; collecting, by a brightness collecting device, brightness information on the projection planes separately, and sending the brightness information to the projection device; receiving, by a processing unit, the brightness information, and obtaining an actual brightness value of projection of the projection device after processing the brightness information; determining whether the actual brightness value is within a preset brightness value range of the projection device; when the actual brightness value is not within the preset brightness value range; adjusting, by a brightness adjusting unit, the projection brightness of the projection device until the actual brightness value falls within the preset brightness value range.

主权项

1. A projection system, comprising at least one projection device, wherein each of the at least one projection device includes:
a projection unit, configured to project an image on a projection plane; a processing unit, configured to
receive brightness information,obtain an actual brightness value of projection of the projection device after processing the brightness information, anddetermine whether the actual brightness value is within a reference brightness value range; and a brightness adjusting unit, configured to control the projection unit to adjust projection brightness of the image on the projection plane so that the actual brightness value falls within the reference brightness value range.
