Imaging system

An imaging system comprising:

• an imaging device which photoelectrically reads fluorescence or chemiluminescence emitted from an object to image the object;
• a plurality of terminal devices which output control information for controlling the imaging device to the imaging device;
• and
• an authorization unit which gives the respective terminal devices an authority to specify controllable functions of the imaging device,
• wherein the authorization unit switches between
• a first state where the respective terminal devices are given a first authority to exclusively occupy a part of functions of the imaging device and to bring the part of functions into a controllable state;
• and
• a second state where one terminal device among the plurality of terminal devices is given a second authority to exclusively occupy and control the part of functions and to release the occupation, and the terminal devices other than one terminal device are given a third authority with the restriction of the control of the part of functions.
