Abstract:
1. A camera control system comprising: a plurality of camera apparatus each including at least a camera unit; camera control units being coupled to said plurality of camera apparatus by cables, respectively, including a memory unit storing setting values of the camera control unit and of an associated camera apparatus, a signal adjuster adjusting video and voice signals fetched from the camera apparatus with the setting value and outputting the adjusted video and voice signals, a video encoder for digitizing an image from the adjusted video signal, a character generator converting the setting value into a predetermined character, a mixer outputting the adjusted video signal overlapped with characters from the character generator, a CPU controlling the camera apparatus with the setting value remotely, an operation unit comprised of switches for user operation, a camera setting condition acquiring unit transmitting a command to the camera apparatus and reading the setting value set in the camera apparatus via a camera I/F, a camera setting unit supplying a setting value to the camera apparatus via the camera I/F, and a power supply feeding electric power to the camera apparatus; at least one base station including a database for storing the setting values concerning at least video quality of said plurality of camera apparatus and corresponding said camera control units and a chromatic correction value, together with images picked up by the camera apparatus and digitized by the video encoder; and a transmission network path for connecting the respective camera control units to said base station, whereby on the basis of the user operation, one of the camera control units transmits a command to said database for downloading an arbitrary setting value, modifies setting values of said corresponding camera control unit with said downloaded arbitrary setting value and outputs a video signal overlapped with characters so that user knows an image and the modified setting value set to the camera control unit, a setting value registered by one of the camera control units in the database is down loaded in response to a request from another camera control unit.
