Title:
LIGHTING SYSTEM FOR IN-VEHICLE CAMERA
Document Type and Number:
WIPO Patent Application WO/2021/010201
Kind Code:
A1
Abstract:
Provided is a light system for an in-vehicle camera that can improve an image recognition rate by reducing overexposure and underexposure of an image and adjusting contrast when shooting is performed with the in-vehicle camera. The present invention comprises an irradiation lamp (5) that irradiates a shooting area of an in-vehicle camera (4) and a control unit (6) that controls the irradiation lamp (5). An object detection unit (11) of the control unit (6) extracts a defect region S such as the overexposure or the underexposure of an image (51) of the camera (4), simply performs image recognition processing on the defect region S, and detects an object (21) to be recognized. An irradiation lamp adjustment unit (12) of the control unit (6) adjusts, on the basis of the brightness of the detected object (21), the wavelength λ of the irradiation light of the irradiation lamp (5). When the adjusted irradiation lamp (5) is turned on, the shooting is performed by the camera (4).
