LIGHT DISTRIBUTION CONTROL DEVICE, LIGHT PROJECTION SYSTEM, AND LIGHT DISTRIBUTION CONTROL METHOD

摘要

To provide a light distribution control device capable of determining whether light distribution control of visible light is performed correctly even when a visible light image partially has a dark region which is not irradiated with visible light, a light projection system, and a light distribution control method.SOLUTION: A light distribution control device 60 includes: an identification part 61 that obtains a position of a dark portion on the basis of an image including at least visible light among images obtained by imaging an imaging region including a specific subject by an imaging device 20 sensing both visible light and near infrared light, obtains a position of the specific subject included in an image including near infrared light on the basis of an image including at least near infrared light, and identifies a position of a dark portion in the specific subject on the basis of a corresponding relationship between the position of the dark portion and the position of the specific subject; and a determination part 62 that determines whether the position of the dark portion in the specific subject is appropriate on the basis of the identification result of the identification part 61.SELECTED DRAWING: Figure 1
