Embodiment Construction

[0071] Hereinafter, an imaging device, a method of controlling the imaging device, an imaging system, and a method of controlling the imaging system according to each embodiment will be described with reference to the drawings.

[0072]

[0073] First, use figure 1 , the overall configuration of the imaging device 101 of the first embodiment will be described. figure 1 The imaging device 101 of the first embodiment shown is an imaging device capable of shooting in three modes: normal mode, night vision mode, and intermediate mode. The night vision mode is suitable for environments where there is almost no visible light, such as at night, and the intermediate mode is suitable for environments where there is a small amount of visible light.

[0074] Both the night vision mode and the intermediate mode are infrared light irradiation modes that shoot while irradiating infrared rays in an environment without visible light. The infrared light irradiation mode can be a night visi...

Abstract

The first irradiation control part (71) of the imaging device (101) controls the first infrared irradiator (9) capable of irradiating each infrared light of a plurality of wavelengths of infrared light to selectively irradiate the infrared rays of the plurality of wavelengths. Light. An imaging unit (3) of an imaging device (101) images a subject while being irradiated with infrared light by a first infrared irradiator (9). The synchronous signal transmitting part (76t) of the imaging device (101) transmits a synchronizing signal to the outside, and the synchronizing signal is used to make the second irradiation control part of the imaging device other than the imaging device (101) irradiate with the second infrared ray. The timing at which the infrared light is irradiated by the first infrared irradiator (9) is synchronized with the timing at which the first irradiation control unit (71) irradiates the infrared light through the first infrared irradiator (9).

Description

technical field [0001] The present invention relates to an imaging device, a control method of the imaging device, an imaging system, and a control method of the imaging system. Background technique [0002] Conventionally, in an environment where there is almost no visible light, such as at night, a method of irradiating the subject with infrared light with an infrared irradiating lamp and photographing the infrared light reflected from the subject has been used to photograph the subject. This method is an effective imaging method when a lamp for irradiating visible light cannot be used. [0003] However, the video obtained by photographing the subject by this imaging method is a black and white video. Objects are sometimes difficult to identify in black and white video. If it is possible to shoot color video even in an environment without visible light, it can improve the recognition of objects. For example, in order to improve the visibility of objects, it is desirable...
