Abstract
A driver monitoring apparatus includes: a driver monitoring camera configured to obtain an image of a user while adjusting an irradiation range of irradiated light; and a driver state sensor configured to request the driver monitoring camera to adjust the irradiation range depending on an operation mode. The driver monitoring apparatus is capable of improving reliability in monitoring a driver state by controlling an irradiation range and intensity of lighting depending on an operation mode and an external environment at the time of monitoring the driver state to irradiate light to only a region of interest.
Claims9
A driver monitoring apparatus comprising:
- a driver monitoring camera configured to obtain an image of a user while adjusting an irradiation range of irradiated light;
- and
- a driver state sensor configured to request the driver monitoring camera to adjust the irradiation range to be either a face region or an eye region depending on whether an operation mode of the driver monitoring apparatus is either a face tracking mode or an eye tracking mode,
- wherein, when a light reflecting point is detected in the obtained image of the user at a time of irradiating light to the eye region, the driver monitoring camera decreases the irradiation range to a predetermined ratio based on position information of a pupil.
