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.

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.
