Camera device, imaging system, control method, and program

A method for controlling a camera device comprising an imaging unit that continuously acquires captured image data, a pan/tilt mechanism that adjusts an imaging direction of the imaging unit, a controller including circuitry that controls the pan/tilt mechanism, a camera-side tracking processing unit that analyzes the captured image data to acquire first target information indicating a position of a tracking target and outputs the first target information, a camera-side communication unit including circuitry that can communicate with a terminal device which operates the camera device and receives second target information from the terminal device, a communication monitoring unit that monitors a communication state with the terminal device, and the controller that corrects the first target information on the basis of the second target information, the method comprising:

• in a case in which both the first target information and the second target information are input, controlling the pan/tilt mechanism on the basis of the second target information;
• and
• in a case in which only one of the first target information and the second target information is input, controlling the pan/tilt mechanism on the basis of the only one input information of the first target information and the second target information,
• wherein the terminal device corrects the second target information on the basis of the first target information, and corrects the second target information in a case in which, after the communication state that is monitored changes to the disconnected state, the communication state changes to a reconnected state.

A camera device comprising:

• an imaging unit that continuously acquires captured image data;
• a pan/tilt mechanism that adjusts an imaging direction of the imaging unit;
• and
• a controller including circuitry that:
• controls the pan/tilt mechanism;
• and
• analyzes the captured image data to acquire first target information indicating a position of a tracking target and outputs the first target information;
• and
• a camera-side communication unit including circuitry that can communicate with a terminal device which operates the camera device and receives second target information from the terminal device;
• the controller further corrects the first target information on the basis of the second target information,
• wherein, in a case in which both the first target information and the second target information are input, the controller controls the pan/tilt mechanism on the basis of the second target information, and
• in a case in which only one of the first target information and the second target information is input, the controller controls the pan/tilt mechanism on the basis of the only one input information of the first target information and the second target information,
• wherein, on the basis of the first target information at a first time which is acquired by analyzing first captured image data acquired at the first time, the camera-side tracking processing unit analyzes second captured image data acquired at a second time after the first time to acquire the first target information at the second time, and
• in a case in which the first target information at the first time is corrected on the basis of the second target information, the camera-side tracking processing unit acquires the first target information at the second time on the basis of the corrected first target information at the first time.
