Exposure Period. Expressed in terms of a continuous variable, such as the time equipment is operating, or as a function of a discrete variable, such as the number of demands (also called cycles in some tests) imposed on a piece of equipment.
Imaging device, imaging control method, and imaging control program
While deterioration of image quality accompanying an irradiation period is suppressed, deterioration of image quality accompanying a shortage of exposure time is suppressed to be lower. A photographing apparatus includes a first camera and a second camera having sensitivity to infrared light, a first light projector and a second light projector that respectively irradiate infrared light to photographing ranges of the first camera and the second camera, and a control device that controls the cameras and the light projectors. An irradiation range of infrared light based on the first light projector partially overlaps an irradiation range of infrared light based on the second light projector. A photographing image of the first camera is an image having a higher priority than a photographing image of the second camera. The control device controls so that a first irradiation / exposure period in the first light projector and the first camera and a second irradiation / exposure period in the second light projector and the second camera do not overlap in a unit photographing period, and the first irradiation / exposure period in the unit photographing period is changed according to a value of a dynamic range in the photographing image of the first camera.
