20080204256 | Sleep warning apparatus - A sleep warning apparatus includes a stimulation generating portion, a reaction detecting portion, a warning determining portion, and a warning generating portion. The stimulation generating portion generates stimulation to a person before a warning is given to the person. The stimulation is used to take reaction of the person. The reaction detecting portion detects the reaction of the person to the stimulation when the stimulation generated by the stimulation generating portion is given to the person. The warning determining portion determines whether or not the warning is required to be given to the person depending on whether or not the reaction detecting portion detects the reaction of the person to the stimulation. The warning generating portion gives the warning to the person when the warning determining portion determines that the warning is required to be given to the person. | 08-28-2008 |
20080267600 | Face image capturing apparatus - A face image capturing apparatus includes a camera, an on-axis illuminator, an off-axis illuminator, an illumination control device, an image capturing control device, and a luminance calculation process device. The camera repeatedly captures an image of a face of an occupant of a vehicle. The illumination control device is configured to adjust an illumination condition of light applied to the face of the occupant. The image capturing control device is configured to control the camera 10 to capture the image of the face at an image capturing timing that is synchronized with a timing for adjusting the illumination condition. The luminance calculation process device is configured to perform a luminance calculation process by using a bright pupil face image, a dark pupil face image, and an ambient light face image. | 10-30-2008 |
20080303915 | Face image capture apparatus - A face image capture apparatus for a vehicle repeatedly performs an output of a difference image to an image ECU. When the number of times of outputs reaches a predetermined number of times, a bright face image from which an influence of disturbance light is not removed is outputted to the image ECU. Thereby, the image ECU can determine an environment (daytime, nighttime, etc.) outside the vehicle based on the bright face image outputted in addition to the difference image. | 12-11-2008 |
20090097701 | Sleepiness level determination device for driver - A sleepiness level determination device includes: a detector processing a face image of an user and for detecting an eye image of the user based on the face image; a characteristic value calculating unit calculating a characteristic value regarding the eye based on the eye image; a sleepiness level determining unit determining a sleepiness level based on the characteristic value; and a reliability calculating unit calculating reliability of the sleepiness level based on the characteristic value. | 04-16-2009 |
20100090839 | DRIVER MANAGEMENT APPARATUS AND TRAVEL MANAGEMENT SYSTEM - In a driver management apparatus for managing the driver of a vehicle, a state estimating means ( | 04-15-2010 |
20120188355 | FACE IMAGING SYSTEM AND METHOD FOR CONTROLLING THE FACE IMAGING SYSTEM - A projection unit projects light to a predetermined projection region in which a user's face is supposed to be located. An imaging unit images a region including the projection region projected with light from the projection unit. A proximity detection unit detects that the user's face approaches the projection unit. A first projection control unit causes the projection unit to stop or dim projection of light when the proximity detection unit detects the approach of the user's face. | 07-26-2012 |
20130120574 | STATE MONITOR APPARATUS - In a state monitor process, it is determined whether a stop state, which requires a stop of a function of a state monitor apparatus, takes place based on detection signals from sensors, namely, it is determined whether an installed position of the state monitor apparatus is displaced from a fixing position or prespecified position. When the installed position of the state monitor apparatus is not displaced from the fixing position, it is determined that the stop state does not take place, permitting a light emitter to irradiate a defined irradiated area with near-infrared lights to capture an image of a driver. When the installed position of the state monitor apparatus is displaced from the fixing position, it is determined that the stop state takes place, executing a restriction process including a reduction process to reduce an emission of the near-infrared lights and a warning output process. | 05-16-2013 |
