IMAGE ACQUISITION SYSTEM AND METHOD OF AUTHENTICATING IMAGE ACQUISITION DEVICE IN THE IMAGE ACQUISITION SYSTEM
First Claim
1. An image acquisition system comprising an image acquisition device having an image acquisition unit and a commanding device configured as a member separate from an image acquisition device proper to transmit a command for controlling the image acquisition device to the image acquisition device proper so that the image acquisition device can perform an operation corresponding to the command, the image acquisition device including:
- an authentication command receiving unit configured to receive an authentication command which is transmitted from the commanding device and contains authentication information used by the image acquisition device to authenticate the commanding device;
a general command receiving unit, arranged separately from the authentication command receiving unit, configured to receive a general command which is transmitted from the commanding device and not contains the authentication information;
an authentication command recognition unit configured to recognize the authentication command received by the authentication command receiving unit; and
a function limiting unit configured to limit a function of the image acquisition device based on the authentication command recognized by the authentication command recognition unit.

31. An authentication method for an image acquisition device, wherein authentication is carried out between the image acquisition device having an image acquisition unit and a commanding device configured as a member separate from the image acquisition device to transmit a command to the image acquisition device proper to control the image acquisition device in such a manner that the image acquisition device can perform an operation corresponding to the command, the method comprising, in the image acquisition device:
-
receiving an authentication command, which is transmitted from the commanding device and contains authentication information used by the image acquisition device to authenticate the commanding device, by an authentication command receiving unit configure to receive the authentication command, the authentication command receiving unit being separate from, a general command receiving unit configured to receive a general command which is transmitted from the commanding device and not contains the authentication information; recognizing the authentication command thus received; and limiting a function of the image acquisition device based on the authentication command thus recognized.
