1. An image acquisition system comprising:
- an image acquisition device having an image acquisition unit;
a commanding device configured as a member separate from the image acquisition device to transmit a command for controlling the image acquisition device to the image acquisition device so that the image acquisition device can perform an operation corresponding to the command; and
an ability switching unit configured to switch an ability to transmit/receive the command between the commanding device and the image acquisition device;
wherein the command includes one of a general command not containing authentication information and an authentication command containing the authentication information, the authentication information enabling the image acquisition device to authenticate the commanding device;
wherein the ability switching unit includes a command transmission/reception ability switching unit configured to reduce the command transmission/reception ability for the authentication command as compared with the command transmission/reception ability for the general command;
wherein the image acquisition device includes;
a command reception unit configured to receive the command transmitted from the commanding device;
an authentication information recognition unit configured to recognize the authentication information contained in the authentication command received by the command reception unit; and
a function limiting unit configured to limit a predetermined function of the image acquisition device based on the authentication information recognized by the authentication information recognition unit;
wherein the authentication information recognition unit of the image acquisition device further includes a command determination unit configured to determine a content of the authentication command received by the command reception unit;
wherein the image acquisition device further includes a mode setting unit configured to, in a case in which the content of the authentication command received by the command reception unit is an authentication mode switching command for limiting the function of the image acquisition device, set an authentication mode of the image acquisition device in accordance with the authentication mode switching command, andwherein the function limiting unit of the image acquisition device limits the function of the image acquisition device in accordance with the authentication mode set by the mode setting unit.

Abstract
An image acquisition system includes a camera as an image acquisition device and a commanding device configured as a member separate from the camera to transmit a command for controlling the camera to the camera so that the camera can perform the operation corresponding to the command. The ability to transmit/receive the command between the commanding device and the image acquisition device is switchable.

21. An image acquisition device authenticating method for carrying out authentication between an 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 for controlling the image acquisition device to the image acquisition device so that the image acquisition device can perform an operation corresponding to the command, the method comprising:
-
switching an ability for command transmission/reception between the commanding device and the image acquisition device; wherein the command includes one of a general command not containing authentication information and an authentication command containing the authentication information, the authentication information enabling the image acquisition device to authenticate the commanding device; wherein the switching comprises reducing the command transmission/reception ability for the authentication command as compared with the command transmission/reception ability for the general command; wherein in the image acquisition device, the method further comprises; receiving the command transmitted from the commanding device; recognizing the authentication information contained in the received authentication command; limiting a predetermined function of the image acquisition device based on the recognized authentication information; wherein the recognizing further comprises determining a content of the authentication command received by the command reception unit; wherein in a case in which the content of the received authentication command is an authentication mode switching command for limiting the function of the image acquisition device, the method further comprises setting an authentication mode of the image acquisition device in accordance with the authentication mode switching command, and wherein the limiting comprises limiting the function of the image acquisition device in accordance with the set authentication mode.
