  • Patent number: 8542278
    Abstract: A data thinning unit prepares thinned images by extracting only one component in raw data of each of a standard image and reference image, a block extracting unit extracts a search block and a template block for finding residual differences, a luminance difference comparing unit obtains a difference between the maximum value and the minimum value of luminance values of each block, and, when smaller than a threshold value, excludes this from a scope of acquisition of residual differences. The residual difference acquiring unit acquires residual differences from blocks which were not excluded, a block selecting unit selects a predetermined number of blocks having small residual differences, and a hand shake (blur or unintentional movement) acquiring unit finds a position of the template block at which the residual difference becomes the minimum, calculates a center value of all positions, and defines the same as the amount of hand shake.

  • Publication number: 20100253495
    Abstract: Every time a camera transmits a picked-up face image to an ECU, the ECU detects a face area from the transmitted face image, and corrects an exposure time so as to have brightness most appropriate to determine a facial direction and the condition of eyes at the detected face area. The corrected exposure time is notified to the camera, and the camera picks up an image of the face of a driver at the notified exposure time. Accordingly, the ECU analyzes a face image which is periodically picked up with the most appropriate brightness regardless of a change in an environment, and determines whether or not a driver is doing a hazardous driving.
