Publication number: 20140062704Abstract: A drowsiness-estimating device capable of improving the precision of drowsiness estimation by eliminating the effect of individual differences. In the device, a recurrence required time-calculating part (103) calculates the recurrence required time, which is the time needed, after a detection time when an action is detected, for a drowsiness estimation parameter value acquired after the detection time to return to the value of the drowsiness estimation parameter acquired before the detection time. A drowsiness-estimating part (104) estimates the level of drowsiness of the drowsiness-estimation subject on the basis of the calculated recurrence required time. To be specific, the drowsiness-estimating part (104) maintains a drowsiness level-estimating table in which each of multiple time ranges is correlated with a possible drowsiness level, and specifies a possible drowsiness level that corresponds to the time range, among the multiple time ranges, with which the recurrence required time is associated.Type: ApplicationFiled: May 25, 2012Publication date: March 6, 2014Applicant: PANASONIC CORPORATIONInventors: Hiroyuki Kubotani, Hiroki Kitajima

Publication number: 20130142416Abstract: A detection device capable of reliably detecting an object to be detected. An intersection region pattern setting unit (106) sets a configuration pattern of a first intersection region pattern group in sequence for each unit image pair. Each intersection region pattern is defined by set image information which denotes locations and sizes of regions (where n is a natural number greater than 1) within respective unit images (e.g., unit image plane coordinates), as well as whether each region is set within either or both of a first unit image and a second unit image. A detection unit (108) detects the object to be detected, based on a total feature value relating to each configuration pattern of the first intersection region pattern group, computed by a feature value computation unit (107), and a strong identification apparatus configured from a plurality of weak identification apparatuses and stored in an identification apparatus storage unit (112).Type: ApplicationFiled: December 20, 2011Publication date: June 6, 2013Applicant: PANASONIC CORPORATIONInventors: Sotaro Tsukizawa, Hiroyuki Kubotani, Zhiheng Niu, Sugiri Pranata

Publication number: 20130044000Abstract: Provided are an awakened-state maintaining apparatus and an awakened-state maintaining method that maintain an awakened-state of a driver. In the awakened-state maintaining apparatus (100), a visual-stimulation control unit (107) calculates an initial displaying position that is in accordance with the product of initial setup time and detected vehicle speed. A displaying means displays on the initial displaying position a visual stimulation image pertaining to a visual-stimulation virtual object that will evoke an awakened-state, and also updates the visual stimulation image using a visual effect wherein the visual-stimulation virtual object is displayed so as to seemingly approach the vehicle at the detected speed, in accordance with the time elapsed since the visual stimulation image was first displayed.Type: ApplicationFiled: April 25, 2011Publication date: February 21, 2013Applicant: PANASONIC CORPORATIONInventors: Wataru Nakai, Hiroyuki Kubotani, Yoshinobu Uno

Patent number: 8085140Abstract: A traveling information providing device is provided in which a surrounding information corrector acquires surrounding information on the condition surrounding a vehicle equipped with the device. An object extractor extracts a safety confirmation object the safety of which must be confirmed by a driver from the surrounding information acquired by the surrounding information collector. A line-of-sight detector detects a line-of-sight direction of the driver. A visibility calculator receives the extracted safety confirmation object and the line-of-sight direction of the driver and calculates visibility in consideration of the driver's peripheral vision with respect to the safety confirmation object according to the distance or the angle from the driver's line-of-sight direction to the object. An information presenter presents safety confirmation to the driver depending on the calculated visibility.Type: GrantFiled: September 4, 2007Date of Patent: December 27, 2011Assignee: Panasonic CorporationInventors: Makoto Mochizuki, Hirofumi Nishimura, Hiroyuki Kubotani, Hisashi Kurokawa
