  • Patent number: 6996255
    Abstract: The method for measuring speed is performed by dividing the time sequence image data A into long and narrow frames (step 401). Next, the framed images and the time sequence image data B produced by the line scan camera B are correlated to obtain a moving time (step 402). Next, a moving time of each framed image and a corresponding moving distance are obtained to compute a moving speed (step 403). Next, scale of a specific shape pattern and the like is corrected using the moving speed obtained to match the scales in the two image sequences A and B to obtain a similarity degree (step 404). Next, a threshold value is applied to the similarity degree to recognize the specific shape pattern, thereby recognizing that the images are produced by a moving vehicle.

  • Patent number: 6256275
    Abstract: When a disc is driven at a low speed, the number of tracks crossed by a beam spot of an optical pickup (3) is determined as the number of crossing tracks corresponding to an amount of mass eccentricity of the disc. If this number of crossing tracks exceeds a first threshold value, the disc is rejected as a non-conforming disc. When the disc is driven at a high speed, the number of tracks crossed by the beam spot is determined, a value remaining by subtracting the number of crossing tracks at the low speed from the number of crossing tracks at the high speed is determined as an amount of vibration produced owing to a mass eccentricity of the disc. Thus, a disc drive which can make an extremely precise detection of a magnitude of vibration resulting from the mass eccentricity of the disc without using a sensor component for detecting the vibration can be provided.
