摘要： PROBLEM TO BE SOLVED: To reduce the number of part items and power consumption and prevent the generation of heat and the lowering of service life of a light source. SOLUTION: A light source 6 for the back light of a display 5 is driven by a circuit part 8 and irradiates with the luminance proportional to the light receiving quantity of an optical sensor 9. A shading plate 11 is interlocked with a falling-type hologram combiner 2. When the hologram combiner 2 is put in a leveled state, the shading plate 11 is positioned between the optical sensor 9 and the light receiving aperture 10 to shut out the light from the external world and to act in such a way as to hinder the light from reaching the optical sensor 9. At the leveled time of the hologram combiner 2, the light receiving quantity of the optical sensor 9 is reduced by a large margin, so that the supply electric energy to the light source 6 is reduced by a large margin.

摘要： PROBLEM TO BE SOLVED: To provide an electrocardiographic detector capable of rationally suppressing various high frequency noises by a simple constitution.SOLUTION: In the signal supply parts 2 and 3 of an electrocardiographic sensor, an electrode conductor part 15 connected to the non-inverse input terminal (+) of an operational amplifier 22 and a parasitic conductor part 30 connected to the inverse input terminal (-) of the operational amplifier 22 becomes almost the same in potential in a voltage follower circuit 20 to guard the leakage current from the electrode conductor part 15 to the ground. Since the capacitor Cs connected to the inverse input terminal (-) and non-inverse input terminal (+) of the operational amplifier 22 in parallel is formed by the parasitic capacity produced between the electrode conductor part 15 and the parasitic conductor part 30, a high frequency signal of cut-off frequency or above is prevented from being outputted from a voltage follower circuit 20 by the impedance thereof. By this constitution, the same effect can be obtained without separately providing an exclusive low-pass filter.

摘要： PROBLEM TO BE SOLVED: To provide technologies on a method for accurately measuring the state of the biological activity such as the respiration rate and the heart rate from a captured image of the face of a subject by eliminating the influence of the transfer and the body motion of the subject.
SOLUTION: A specific area detection part 21 detects three-dimensional coordinates in a specific area of the face from the face image captured by an imaging device 1. A luminance acquisition part 22 calculates an average luminance of the specific area. A face direction/position detection part 23 detects the direction of the face of the subject and the position of the specific area as components of the body motion based on the three-dimensional coordinates at respective feature points constituting the specific area. A luminance correction part 24 regulates and corrects the average luminance of the specific area calculated by the luminance acquisition part 22 to the luminance corresponding to the frontal face based on the components of the body motion detected by the face direction/position detection part 23. In this way, the influence of the components of the body motion at the luminance in the specific area detected from the target face image to be processed is eliminated. A heart rate calculation part 26 calculates the heart rate of the subject from the time-series luminances corrected by the luminance correction part 24.

摘要： PROBLEM TO BE SOLVED: To provide an awakening degree calculation device capable of improving the detection accuracy of sleepiness.
SOLUTION: The awakening degree calculation device sets a circadian variation in each driver and executes weight function calculation processing in which a weight function for correcting an awakening degree estimated on the basis of a photographed image shows a correspondence relation between a time since a mounted vehicle starts traveling and a correction coefficient and a calculation is made so that influence on an awakening degree due to low reliability of a reference value may be reduced until a second regulated time passes and so that influence exercised on a corrected awakening degree from the weight coefficient may be always constant after the second regulated time passes (S110). Then, an estimation index and a reference value are set (S150), and an awakening degree is calculated according to the estimation index and the reference value (S160). A corrected awakening degree obtained by multiplying the calculated awakening degree by the correction coefficient at the present time is calculated (S170), and warning processing based on the corrected awakening degree is executed (S180).

摘要： PROBLEM TO BE SOLVED: To provide a sleepiness detection device for improving the detecting precision of sleepiness by reducing the erroneous recognition of the generation of sleepiness to be generated due to a downward look.
SOLUTION: This sleepiness detection device is configured to take a photographic image by a camera (S110), and to calculate the arousal of a driver based on the circumstances of the blink of the driver to be detected from the photographic image (S150). Furthermore, after an approximate curve showing the outline shape of the eyelid of the driver is calculated by a downward look detection processing, whether or not the driver is having a downward look is decided (S170). In sleepiness warning processing, when the decision of the downward look detection processing shows that the approximate curve is downward convex, it is decided that the driver is having a downward look, and the previously calculated arousal is corrected so that the deterioration of the arousal due to the downward look can be offset (S190), and the sleepiness of the driver is detected by using the corrected arousal (S200).

摘要： PROBLEM TO BE SOLVED: To provide a sleepiness detector accurately recognizing the shape of the eyelid of a driver and accurately detecting downward gaze.
SOLUTION: In the sleepiness detector, irradiation light is emitted from a light source arranged at a position for projecting a shadow formed at the boundary of a lower eyelid and an eyeball into the eyeball of the driver in a sitting state, and a photography image is photographed by a camera arranged at a position held between a gaze axis and a down axis above the arranging position of the light source 13, which is the position capable of photographing the shadow formed at the boundary of the lower eyelid and the eyeball of the driver (S110). On the basis of the photographed image, the awakeness of the driver is calculated (S150), an approximate curve indicating the contour shape of the lower eyelid of the driver is calculated, and then whether or not the driver has the downward gaze is judged (S170). When the driver has the downward gaze, the calculated awakeness is corrected (S190) so as to offset the decline of the awakeness due to the downward gaze, and the sleepiness of the driver is detected (S200) using the corrected awakeness thereafter.

摘要： PROBLEM TO BE SOLVED: To provide a sleep support device, a program, and a recording medium capable of supporting sleep as a whole, without using a large-scale device, such as sleep polygraph. SOLUTION: In step 110, a pulse wave is measured for one minute, and a fluctuation component at about 0.3 Hz of the pulse intervals is calculated and set to initial value of HF0 for the fluctuation component. In step 120, the pulse wave is measured sequentially at intervals of one minute, the fluctuation component HF at about 0.3 Hz of the pulse intervals is calculated from the measured pulse wave, and the ratio of the change to the initial value (or the rate of increase in the amount of activity of parasympathetic nerves) HF/HF0 is displayed on a user interface 9. In step 130, whether HF/HF0 is greater than a prescribed value is determined. In step 150, since the state is regarded as being suitable for going to bed, the device urges the user to go to bed, by displaying the state on the user interface 9. COPYRIGHT: (C)2006,JPO&NCIPI
