Title:
IMAGING DEVICE, AND IMAGING DEVICE CONTROL METHOD
Document Type and Number:
Japanese Patent JP2020085996
Kind Code:
A
Abstract:
To provide an imaging device that can selectively use a photographing mode capable of photographing subjects on the basis of light of a specific wavelength region.SOLUTION: In an imaging device 1, a diaphragm blade 7d and diaphragm blade 7e are formed of a member transmitting only light of a wavelength region of 730nm to 840nm. When a night photographing mode is set, the imaging device 1 is configured to retreat an infra-red light cut filter 9 from an optical path, and open the diaphragm blade 7d and diaphragm blade 7e. On the other hand, when a distant view clear IR mode is set, the imaging device 1 is configured to retreat the infra-red cut filter 9 from the optical path, and completely close the diaphragm blade 7d and diaphragm blade 7e.SELECTED DRAWING: Figure 7
