IMAGE SWITCHING DEVICE AND IMAGE OUTPUTTING DEVICES

摘要

An image switching device for connecting a plurality of image outputting devices via a digital interface and capable of selecting image outputs sequentially,and image outputting devices. Cameras(101 to 104) are connected to a camera switching device(105) via an IEEE 1394 standard-based digital interface(114). Synchronizing timing signals transmitted in isochronous communication packets from the camera switching device(105) are synchronized with image signals on the camera(101 to 104)sides,each camera(101 to 104)transmits its image signals in synchronous communication packets based on image switching control data transmitted in asynchronous communication packets or isochronous communication packets from a camera switching control unit(106),and the camera switching device(105) selectively receives image data transmitted from a desired camera based on image switching control data.
