Imaging device, imaging control method and imaging control program

Abstract

An imaging device 1 comprises: a first camera 12 and a second camera 22, each sensitive to invisible light; a first and a second irradiation unit 11, 21, configured to irradiate the imaging area of ​​the first and second cameras, respectively, with invisible light; and a control unit 40 configured to control the cameras and the irradiation units. An irradiation area of ​​invisible light by the first irradiation unit partially overlaps an irradiation area of ​​invisible light by the second irradiation unit. An image captured by the first camera has a higher capture priority than an image captured by the second camera.The control unit is configured to perform control such that in an imaging cycle, a first irradiation / exposure period by the first irradiation unit and the first camera and a second irradiation / exposure period by the second irradiation unit and the second camera do not overlap, and the first irradiation / exposure period in the imaging cycle is changed according to a value of a dynamic range in the image taken by the first camera.
