Latest Patents

One of Okada's latest inventions is a bodily state detection apparatus. This apparatus includes a CCD camera, an infrared LED device, a pickup image memory, a pupil extraction circuit, and a bodily state judgment circuit. The CCD camera captures images of a predetermined area that includes the subject person's face. The infrared LED device illuminates the subject in a manner that aligns the optical axis of the camera with the direction of illumination. The pickup image memory temporarily stores the output data from the CCD camera. The pupil extraction circuit is responsible for extracting the subject person's pupil position from the captured images. Finally, the bodily state judgment circuit assesses the subject person's bodily state based on the results from the pupil extraction.

Another significant invention by Okada is a driver photographing apparatus. This device photographs images from reflections on the retinas of a driver in a vehicle, even in the presence of disturbance light, using advanced signal processing techniques. The apparatus consists of a light source that illuminates the driver with a first light beam along a designated optical path, and a sensor that captures a second light beam, which includes reflections from the driver and disturbance light. The light source and sensor are aligned along substantially the same axis. Additionally, the apparatus features a processing circuit that mitigates the effects of disturbance light on the driver's image, along with a detecting circuit that determines the driver's actions based on the captured image.
