Title:
PROJECTION SYSTEM
Document Type and Number:
Japanese Patent JP2020086189
Kind Code:
A
Abstract:
To provide a system that improves a deviation of an application timing of a parameter in a plurality of projection devices.SOLUTION: A projection system comprises a plurality of projectors 100 that project images using a plurality of division frames generated from each of a plurality of frames. The projector 100 comprises: an image processing unit 109 that acquires an amount of statistics of the frame; a network IF108 that acquires an amount of statistics of the frame and information indicative of a frame number from other projection device; and a projection control unit 105 that projects the image on the basis of an object frame. The projection control unit 105 is configured to, when acquiring the amount of statistics of the frame preceding by predetermined pieces of frames from the object frame from other projector 100, determine a projection parameter from the amount of statistics corresponding to the frame preceding by predetermined pieces of frames, otherwise, determine the projection parameter used in projecting the image of the frame prior to the object frame as the projection parameter with respect to the object frame.SELECTED DRAWING: Figure 6
