  • Patent number: 7965871
    Abstract: A moving-state determining device acquires a first overhead image from a bird's-eye image obtained at first image pickup timing and acquires a second overhead image, which can be regarded as the same road surface area as that of the first overhead image, for each of moving directions assumed for the moving body from a bird's-eye image obtained at second image pickup timing different from the first image pickup timing by a predetermined time period. The device compares a degree of similarity between the first overhead image and each of a plurality of second overhead images to acquire the second overhead image with the largest similarity degree as the same road surface area as that of the first overhead image. The device acquires the moving direction and a lateral displacement amount in the moving from a coordinate conversion condition based on which the second overhead image has been obtained.

  • Patent number: 7289645
    Abstract: A hand pattern switch device recognizes a hand pattern from an image of a hand in an image pickup zone and detects a hand motion. One of controlled objects is selected based on the recognized hand pattern and/or hand motion. In accordance with the selected object, a mode of detection of operation information based on hand motion is changed. In a moved distance detecting mode, a moved distance of the hand in the zone is detected as operation information, and in a stop time detecting mode, a stop time of the hand at a stop position to which the hand has been moved in the zone is detected as operation information. The image pickup zone is at a location which is located laterally to a steering wheel and to which a driver can extend his/her arm without changing a driving posture.
