  • Patent number: 9977986
    Abstract: A method of vehicle monitoring includes: obtaining a frame of an image before exposure; outputting a luminance value of each partition of the image, accumulation number of pixels lower than a first set threshold, accumulation number of pixels higher than a second set threshold, to generate an evaluation data; generating eigenvalues of a plurality of illuminance evaluation areas based on the evaluation data and the preset illuminance evaluation area distribution table; estimating the illuminance of an environment of a vehicle according to the eigenvalues of the plurality of illuminance evaluation areas and differentiation characteristics between normal illuminance and low illuminance; switching the region of interest of a current exposing image based on the estimating results, generating a weight table based on the content of the current exposing image and the switched region of interest, controlling the exposing of the region of interest based on the weight table.

  • Patent number: 9124764
    Abstract: The present invention discloses a method, a device, and a system for adjusting image display and belongs to the field of videoconferencing technologies. The method includes: receiving an image of a second conference site and an environmental parameter of the second conference site that are sent by a presence terminal of the second conference site; converting the image of the second conference site according to a pre-stored environmental parameter of a first conference site and the environmental parameter of the second conference site to obtain an image for display, wherein a conference site environmental parameter of the image for display is consistent with the environmental parameter of the first conference site; and displaying the image for display.
