For example, the control microcomputer 14 controls the lighting unit 2 to turn on and off according to instructions from a host device such as a remote controller, a controller 9, or an external server (not shown).

Further, the control microcomputer 14 selects the control mode 2 when the power supply to the image pickup unit 3 is not cut off, and in accordance with this, controls the lighting of the illumination unit 2 in conjunction with the image pickup unit 3. For example, the control microcomputer 14 determines whether or not there is sufficient brightness from the image of the camera 33, and turns on the LED when there is not enough brightness.

Further, the control microcomputer 14 selects the control mode 3 when the power supply to the image pickup unit 3 is not cut off, and does not perform the on / off control of the illumination unit 2 according to this. For example, the control microcomputer 14 turns off the lighting unit 2.

Further, the control microcomputer 14 selects the control mode 4 when the power supply to the image pickup unit 3 is cut off, and controls the lighting unit 2 to turn on and off accordingly. For example, the control microcomputer 14 controls the lighting unit 2 to turn on and off according to instructions from a host device such as a remote controller, a controller 9, or an external server (not shown).

Further, the control microcomputer 14 selects the control mode 5 when the power supply to the camera 33 is cut off, and controls the lighting unit 2 to turn on and off accordingly. For example, the control microcomputer 14 estimates whether the surrounding camera 33 has sufficient brightness by using an illuminance sensor or the like, and turns on the LED when the surrounding camera 33 does not have sufficient brightness.

In this way, for example, when the above control mode 1 is selected, the camera 33 can be operated even when the lighting unit 2 is turned off in an environment where the surroundings are bright such as in the daytime. .. Further, when the above control mode 2 or 5 is selected, it is possible to turn on the illumination unit 2 when the surroundings are dark when shooting with the camera 33.
