The present invention discloses a method, device, and system for multipoint video communication. The method includes: determining whether an image acquisition target exists in an image acquisition area within a current period; and if the image acquisition target is absent from the image acquisition area within the current period, skipping reporting image information of the image acquisition area within the current period to a multipoint control unit. The method, device, and system for multipoint video communication disclosed by the present invention can implement that an image acquisition target always exists in an image corresponding to the image information reported to the multipoint control unit, which avoids a waste of system resources caused by absence of an image acquisition target from an image corresponding to image information reported to the multipoint control unit, thereby saving the system resources, reducing load of the multipoint control unit, and improving overall performance of the system for multipoint video communication.
