ABSTRACT:
An image switching device for connecting to a plurality of image output devices via a digital interface having the capability of selecting image outputs sequentially of the image outputting devices. Cameras (101to104) 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 (101to104) sides, each camera (101to104) 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.
