1. An imaging system comprising:

  • a moving body;

    an imaging unit that is provided in the moving body;

    a captured data transmission unit that transmits captured data obtained by an imaging operation of the imaging unit;

    a captured data receiving unit that receives the captured data transmitted from the captured data transmission unit;

    a pan/tilt operation unit that instructs the imaging unit to perform at least one of a pan operation or a tilt operation;

    an imaging operation unit that is connected to the imaging unit so as to communicate with the imaging unit and transmits an imaging control signal for operating the imaging unit to the imaging unit;

    a display unit that displays a captured image indicated by the captured data received by the captured data receiving unit on a display screen;

    a coordinate designation unit that designates designation coordinates which are coordinates of a movement target and movement destination coordinates which are coordinates of a movement destination of the movement target in the image displayed on the display screen of the display unit in a case in which an angle of view of the imaging unit is adjusted;

    an angle-of-view adjustment operation unit that calculates pan/tilt operation parameters applied to the pan/tilt operation unit, using the designation coordinates and the movement destination coordinates;

    an angle-of-view adjustment period calculation unit that calculates an angle-of-view adjustment period which is a period from the designation of the designation coordinates to the adjustment of the angle of view of the imaging unit;

    a movement state calculation unit that calculates motion parameters indicating a moving direction and a movement distance in a case in which the imaging unit is moved by the movement of the moving body for the angle-of-view adjustment period from the captured data obtained by the imaging operation of the imaging unit;

    a pan/tilt operation parameter correction unit that corrects the pan/tilt operation parameters calculated by the angle-of-view adjustment operation unit on the basis of the motion parameters calculated by the movement state calculation unit and the angle-of-view adjustment period calculated by the angle-of-view adjustment period calculation unit in a case in which the angle of view of the imaging unit is adjusted; and

    a pan/tilt operation command unit that transmits a signal corresponding to the pan/tilt operation parameters to the pan/tilt operation unit, using communication, and transmits a signal corresponding to the pan/tilt operation parameters corrected by the pan/tilt operation parameter correction unit to the pan/tilt operation unit.
