The visible light camera 5 is connected to a lens 8, and includes a zoom motor 10 that performs a zoom operation of the lens 8 and a focus motor 11 that performs a focus operation, and outputs a visible light image to the video switching unit 7. A lens 9 is connected to the infrared camera 6, and a zoom motor 12 that performs a zoom operation of the lens 9 and a focus motor 13 that performs a focus operation are configured to output an infrared light image to the video switching unit 7.

  The main body unit 14 includes a CPU 15 having a clock function, a preset memory 16, a tilt control unit 17, a tilt motor 18, a pan control unit 19, a pan motor 20, and sensors (not shown) such as an encoder for detecting pan / tilt positions. Is done.

  The pedestal unit 12 includes a communication unit 22 and a video output unit 23.

  The pan head apparatus first receives an operation signal from the remote controller 9 through the communication unit 22. The CPU 15 interprets the received operation signal and performs an operation suitable for the operation signal. When the operation signal is a panning / tilting drive command, the pan motor 20 and the tilt motor 18 are driven by controlling the pan control unit 19 and the tilt control unit 17. If the control command is for various zoom / focus lenses, the zoom motor 10, the zoom motor 13, the focus motor 11, and the focus motor 13 are driven.

  The CPU 15 determines which of the visible light image and the infrared light image is output based on the conditions preset in the preset memory 16. The preset condition item is one of a pan position, a tilt position, a zoom position, a focus position, a time condition, or a combination thereof. These position conditions are set in a predetermined range. For example, if the movable range of the entire pan is 0 ° to 350 ° and the pan position condition is 170 °, the range is ± 10 °, and if the current pan position is 160 ° to 180 °, the condition is met.

  The image switching unit 22 outputs either a visible light image or an infrared light image to the image output unit 23 according to a command from the CPU 15.

  The video output unit 23 outputs the video signal from the video switching unit 22 to the video monitor 3.

  Next, the determination of which of the visible light image and the infrared light image is output based on the condition items preset in the preset memory 16 by the CPU 15 in this embodiment will be described with reference to the flowchart of FIG.

  In step S100, the CPU 15 determines whether there is a condition that is preset in the preset memory 16 and any one of the pan position, tilt position, zoom position, focus position, and time condition is applied. If there is, the process proceeds to step S101, and if not, the process proceeds to step S107.

  In step S101, if the pan position is in the condition item, it is determined whether the pan position is within the condition. If the condition or the pan position is not in the condition item, the process proceeds to step S102. If the condition is not satisfied, the process proceeds to step S107.

  In step S102, if the tilt position is in the condition item, it is determined whether the tilt position is within the condition. If the condition is not in the condition or the tilt position is not in the condition item, the process proceeds to step S103, and if not in the condition, the process proceeds to step S107.

  In step S103, if the zoom position is in the condition item, it is determined whether the zoom position is within the condition. If the condition is not within the condition or the zoom position is not in the condition item, the process proceeds to step S104. If the condition is not satisfied, the process proceeds to step S107.

  In step S104, if the focus position is in the condition item, it is determined whether the focus position is within the condition. If the condition is not in the condition or the focus position is not in the condition item, the process proceeds to step S105, and if not in the condition, the process proceeds to step S107.

  Subsequently, in step S105, if the time is in the condition item, it is determined whether the time is within the condition. If it is not within the condition or the time is not in the condition item, the process proceeds to step S106, and if not within the condition, the process proceeds to step S107.

  In step S106, in response to a command from the CPU 15, the video switching unit 22 outputs the infrared light video to the video output unit 23, and the process returns to step S100.

  In step S107, the video switching unit 22 outputs a visible light video to the video output unit 23 according to a command from the CPU 15, and the process returns to step S100.

  With the above configuration and operation, it is possible to provide a camera head device that can capture an optimal visible light image and infrared light image.
